Saya sudah lebih dari 8 tahun bekerja di bidang automation, control & instrumentation, dan sering bertemu dengan data center atau bangunan industri yang secara teknis “high tech” tapi operasionalnya masih sangat manual: tidak ada CMMS, maintenance sering reaktif, tidak ada pencatatan parameter kritikal secara real-time, banyak damper yang masih harus diset manual, tanpa servo atau motorized actuation. Ini bukan cerita ekstrem—ini situasi banyak di Indonesia.

Masalahnya: tanpa pondasi yang benar, otomatisasi tingkat tinggi (PID kompleks, AI, predictive control) susah dijalankan dan hasilnya bisa mengecewakan atau bahkan kurang impactful. Artikel ini membahas bagaimana secara pragmatis kita bisa bergerak dari “manual” ke “data-driven” dalam kondisi yang belum ideal, tanpa memaksakan teknologi canggih, sambil tetap menghasilkan efisiensi nyata.

Masalah Utama di Lapangan

1. Tidak ada CMMS / plan maintenance formal

Banyak aset tidak tercatat secara sistematis: kapan terakhir diperiksa, kapan filter diganti, kapan pompa diservis. Maintenance sering muncul setelah kegagalan atau keluhan.

2. Damper manual

Fresh air damper, return air damper, balancing damper masih manual tanpa actuator; sering terlupakan karena akses susah, atau setting yang tidak tepat lalu dibiarkan begitu saja.

3. Parameter kritikal tidak terekam real-time

Temperatur supply/return, ΔP filter, CO₂ di ruang padat, flow fan/chiller kadang hanya dicek manual, tidak ada histori data.

4. Minimnya analisa akar masalah / Pareto

Keluhan “ruangan panas”, alarm “temp high” sering hanya diatasi sementara, tanpa root cause analysis.

5. Takut biaya retrofit

Investasi actuator/sensor dianggap mahal, ROI tidak terlihat jelas, takut cepat rusak atau sulit perawatannya.

Peran PLC, HMI, dan BMS

• PLC (Programmable Logic Controller) dapat menjadi pengendali dasar untuk fan, pompa, atau damper. Bahkan sebelum ada BMS penuh, PLC bisa diprogram untuk logika sederhana (ON/OFF, jadwal, step control).
• HMI (Human Machine Interface) penting untuk operator agar parameter kritikal (temperatur supply/return, posisi damper, ΔP filter) terlihat jelas. Dengan begitu operator bisa mengambil keputusan cepat tanpa menunggu laporan manual.
• BMS (Building Management System) berfungsi sebagai integrator yang mengumpulkan data dari PLC/sensor, menampilkan dashboard, alarm, dan laporan historis. Jika BMS penuh belum ada, mini-BMS berbasis gateway + SCADA sederhana bisa menjadi jembatan.

Langkah Bertahap (Roadmap Praktis)

Tahap   | Aktivitas Utama                                | Output                      | Estimasi

———————————————————————————————–

T0      | Inventarisasi aset kritikal, tentukan parameter      | List aset + baseline energi | 1–2 minggu

T1      | Pasang sensor dasar, mulai CMMS/spreadsheet    | Histori data + tiket CMMS   | 2–4 minggu

T2      | Retrofit actuator, VFD, kontrol open-loop                | Damper otomatis, fan variatif| 1–2 bulan

T3      | Analisa Pareto & RCA dengan data                            | Akar masalah teridentifikasi| 1 bulan

T4      | Optimasi lanjut (closed loop/AI)                                  | Feedback loop, ROI lebih jelas| 2–3 bulan

Cara Efisiensi Tanpa PID / AI

• Retrofit actuator penting (fresh air/return damper motorized).
• Pasang VFD di fan/pump untuk kontrol kecepatan sederhana.
• Buat jadwal & lookup table (misalnya damper buka/tutup berdasarkan jam).
• Cleaning & perawatan (filter, coil, damper) untuk efisiensi airflow.
• Logging parameter kunci (T supply/return, ΔP filter, kWh panel) setiap 5–15 menit.

Continuous Improvement (Kaizen)

• Gunakan siklus PDCA (Plan-Do-Check-Act).
• Review data mingguan (kWh, ΔP filter, keluhan suhu).
• Lakukan Pareto analysis bulanan dari CMMS untuk tentukan akar masalah terbesar.
• Libatkan tim maintenance dan operator untuk ide perbaikan kecil (contoh: penjadwalan filter cleaning, optimasi setpoint malam).
• Dokumentasikan setiap perubahan → evaluasi → standar baru jika terbukti efektif.

Contoh Kasus

Satu data center kecil dengan AHU + chiller + damper manual.

• Sebelum retrofit: fresh air damper tetap terbuka penuh malam hari, padahal tidak ada orang. Beban chiller meningkat 10–15%.
• Sesudah retrofit motorized damper: malam hari damper dikurangi, beban cooling turun, tagihan listrik turun beberapa juta per bulan.
• Tambah sensor ΔP filter: filter kotor terdeteksi lebih awal → fan tidak boros → saving 5–10%.

Tantangan & Cara Mengatasinya

• Biaya retrofit tinggi → mulai dari titik kritikal (highest ROI).
• SDM terbatas → training sederhana, dokumentasi, libatkan teknisi sejak awal.
• Sensor rusak/kalibrasi → pilih sensor standar, buat jadwal PM kalibrasi.
• Takut gangguan operasional → retrofit di jam low risk, mulai dari satu unit, siapkan rollback plan.

Kesimpulan

Untuk bangunan “low-tech”, kunci awal bukan AI atau kontrol PID kompleks, tapi fondasi: CMMS, data historis, actuator penting, kontrol sederhana, dan RCA. Dengan tambahan PLC dan HMI, operator bisa lebih cepat memantau parameter. BMS dapat menjadi integrator untuk memantau dan mengontrol banyak aset sekaligus. Dengan langkah kecil dan konsisten:

• Energi kipas/AC bisa turun 10–20%.
• Downtime berkurang.
• Umur aset lebih panjang.
• ROI lebih jelas untuk investasi otomasi lanjutan.
• Continuous improvement (Kaizen) menjaga agar efisiensi meningkat terus-menerus.

The post Dari Manual ke Data-Driven: Membangun Fondasi Otomasi HVAC & Pemeliharaan di Data Center dan Bangunan “Low-Tech” appeared first on Nusantara Academy.

Beyond reliability, energy efficiency is another pressing issue. According to the International Energy Agency (IEA, 2023), global data center energy consumption could account for up to 4% of the world’s electricity by 2030 if not properly managed.

The post Data Center Power Quality, Reliability, & Efficiency: Why Is It a Vital Issue? appeared first on Nusantara Academy.

The rapid growth of digital infrastructure in Indonesia has fueled the rising demand for efficient, reliable, and sustainable data centers. One of the most critical aspects of data center management is the cooling system. Cooling is no longer seen merely as keeping equipment cold, but rather as a comprehensive strategy to ensure service reliability, reduce energy consumption, and support environmental sustainability.

The podcast “Do Data Centers Really Need to Be Extremely Cold and Precise? It’s Just a Myth—Find Out the Facts Here” produced by the Nusantara Data Center Academy discusses the paradigm shift in data center cooling, debunks outdated myths, and provides strategic guidance for operators and businesses in Indonesia. This episode is hosted by Sari Oktaviani with two prominent figures in the data center cooling industry:

• Herlin Haryani, President of ASHRAE Indonesia Chapter, who shares insights on technical innovations, real-time monitoring, and energy-efficient cooling strategies.
• Indri Priscillia, Managing Director of PT Tools Air Teknologi Indonesia, who discusses customization, personnel certification, and the importance of local content (TKDN) in data center operations.

Outdated Myths of Data Center Cooling

A long-standing misconception is the belief that data centers must always be maintained at extremely cold conditions. This view originated from an era when servers could only operate within a narrow temperature range, where even a slight increase could cause disruption.

However, according to Herlin Herlianika, advancements in modern server technology have expanded these standards. Servers today can operate optimally within 19–27°C. This means data centers no longer need to maintain ultra-low temperatures, but instead ensure conditions remain within the tolerance range of the equipment. In other words, cooling should be focused on the machines, not on human comfort in the server room.

From Precision Cooling to Energy Efficiency

Precision cooling was once the top priority, as legacy IT equipment could only function within strict ranges of temperature and humidity. With greater flexibility today, the focus has shifted toward energy efficiency.

According to Indri Prisilia, humidity levels that were once tightly maintained at 40–50% can now be extended up to 60% without affecting server performance. What was once seen as the absolute need for precision cooling has now become secondary to efficiency.

This shift also applies to cooling load management. For instance, once the average room temperature is achieved, fans no longer need to run at full capacity. Reducing unnecessary fan startups—which consume significant energy—can save substantial energy when multiplied across multiple racks with dozens of servers.

Energy Efficiency as the Key Priority

Today, cooling is a major strategy for reducing energy consumption, not merely for maintaining stable temperatures. Given that cooling systems can account for up to 40% of a data center’s total energy use, optimization has a direct impact on reducing operational costs and meeting sustainability goals.

Herlin emphasized that adopting energy efficiency aligns with global trends in green data center management. Indonesia, which is experiencing surging data center demand, must seize this momentum by implementing energy-efficient cooling strategies early on.

Multi-Stakeholder Collaboration

The paradigm shift in cooling also impacts human resource requirements.

According to Indri, in the past, an engineer only needed mechanical skills such as welding, valve replacement, or component repair. Today, engineers must also understand software logic, control systems, and automation to optimize cooling efficiency.

A hybrid skill set—combining mechanical expertise with software logic—has become indispensable. The greatest challenge lies in retaining experienced talent, as the industry faces high turnover rates with engineers often moving to competitors.

Data Center Trends and Prospects in Indonesia

Digital consumption among Indonesians—from children to seniors—is rising through social media, e-commerce, and online entertainment. This drives exponential growth in data center demand.

According to Herlin, Indonesia holds enormous potential to become one of Southeast Asia’s leading data center hubs. However, this success relies heavily on the readiness of local talent, so that the industry does not remain dependent on foreign expertise.

Source: Cleantech Group, Revolutionizing Data Center Cooling: Immersion Technologies at the Forefront

Immersion cooling is an increasingly relevant innovation to address Indonesia’s soaring data center needs. This technology immerses servers directly into a special dielectric fluid that absorbs heat with exceptional efficiency. Compared to conventional air-based cooling, immersion cooling provides higher energy efficiency, reduces space requirements, and extends equipment lifespan.

This technology reflects the future direction of Indonesia’s data centers, where operators must not only achieve efficiency but also sustainability, while being ready to adopt innovative solutions aligned with global trends.

Strategic Recommendations for Operators and Businesses

Key strategic takeaways from the discussion include:

• Focus on servers, not rooms – Cooling should target machines, not human comfort.
• Prioritize energy efficiency – Emphasize power consumption, not just precise temperature.
• Participate in certifications and associations – Such as ASHRAE, for updated standards and technology transfer.
• Engage professional consultants – Ensure cooling design matches the specific needs of each data center.
• Invest in human capital – Develop engineers with hybrid competencies in both mechanical and software logic.

Conclusion

The paradigm shift in data center cooling shows that maintaining ultra-low, precise temperatures is no longer the primary priority. The focus has moved toward energy efficiency, flexible ranges of temperature and humidity, and the development of human resources with more holistic skills.

Cross-sector collaboration between associations, government, technology providers, and educational institutions is crucial to building a resilient data center ecosystem in Indonesia.

With the potential for significant growth in demand, energy-efficient cooling strategies, strong collaboration, and the readiness of local talent will determine Indonesia’s success in building a sustainable and globally competitive digital infrastructure.

The post Myths, Trends, and Cooling Strategies for Data Centers: From Precision to Energy Efficiency appeared first on Nusantara Academy.

With the rapid growth of digital infrastructure in Indonesia, the demand for efficient and reliable data centers is increasingly urgent. One critical aspect that determines the performance and sustainability of data center operations is its cooling system.

In the Nusantara Data Center Academy podcast, experts discuss various challenges and innovations in data center cooling in Indonesia, ranging from managing high power density, implementing energy-efficient cooling technologies, to the role of certification and local regulations.

The podcast “3 Factors That Can Optimize Your Data Center PUE”, produced by Nusantara Data Center Academy, discusses the key factors that influence Power Usage Effectiveness (PUE) in data centers, focusing on strategies to balance performance, efficiency, and sustainability. The episode is hosted by Sari Oktaviani and features two main experts:

• Herlin Haryani, President of ASHRAE Indonesia Chapter, who shares insights on technical innovations, real-time monitoring, and energy-efficient cooling strategies.
• Indri Priscillia, Managing Director of PT Tools Air Teknologi Indonesia, who discusses customization, personnel certification, and the importance of local content (TKDN) in data center operations.

During the episode, they explore challenges such as increasing power density, cooling in Indonesia’s tropical climate, and how certified teams and smart designs help achieve low PUE values (<1.5).

Cooling Challenges in Indonesia

One major issue is the increasing server power density, which can reach 20–30 kW per rack. The higher the density, the greater the heat load that the cooling system must handle. In Indonesia, air-based “free cooling” methods are rarely applicable due to the tropical climate, making energy efficiency and system precision extremely important.

Source: Johra (2022), Overview of COP for conventional vapour-compression heat pumps in buildings, Aalborg University.

The comparison chart shows how PUE (Power Usage Effectiveness) varies between data centers in tropical and temperate climates:

• Red line: Data centers in tropical climates, such as Indonesia, where PUE tends to be higher due to hotter outdoor temperatures, requiring more mechanical cooling.
• Blue line: Data centers in temperate climates, which generally have lower PUE because cooler outdoor temperatures allow cooling systems to operate more efficiently.

Importance of Customization and Flexibility

Cooling system providers emphasize customization and flexibility in design. From the initial design stage, raw data from consultants (such as airflow parameters, fan positions, and room dimensions) is sent to the R&D department to create general drawings and technical data. These designs are then reviewed with data center operators to ensure compatibility with specific needs. This flexibility allows data centers to manage high heat loads with maximum efficiency.

Advanced Cooling Technologies

Key innovations discussed include oil-less compressors with a Coefficient of Performance (COP) of 16–18, much higher than the commonly used average COP of 12–13. A higher COP means lower energy consumption for the same cooling output.

Source: Boyd Corporation (2023), Energy Consumption in Data Centers: Air versus Liquid Cooling.

The chart illustrates cooling system efficiency based on COP. The lower line represents standard systems with COP 12–13, which are less energy-efficient, while the upper line represents advanced systems with COP 16–18, which are more efficient and consume less energy for the same cooling output.

Additionally, integrating renewable energy and good building insulation plays a major role in reducing cooling load. These technologies help achieve energy efficiency goals and support the sustainability of data centers in Indonesia.

Role of Certified Personnel

The post Maximizing PUE Efficiency: Data Center Cooling Strategies in Indonesia appeared first on Nusantara Academy.

Cooling is a key factor in maintaining server performance and reliability. In Indonesia, the tropical climate demands continuous cooling throughout the year, unlike subtropical countries that can leverage free cooling during winter.

Server power density has sharply increased from 5–10 kW per rack to 20–30 kW, which also raises cooling demands. Efficient cooling not only maintains server performance but also prevents potential damage and data loss.

The Role of ASHRAE and Global Standards

Herlin Haryani explained that ASHRAE is a global professional association that sets standards for refrigeration and ventilation. ASHRAE conducts research and establishes design standards for refrigeration, heating, and ventilation, widely used by data center designers and consultants. These standards are applied in data center designs worldwide, including in Indonesia, to ensure cooling systems meet safety and energy efficiency criteria.

Meanwhile, Indri Priscillia highlighted the rapid growth of data centers in Indonesia driven by digital transformation, AI, e-commerce, and financial transactions, which further increases data storage needs.

Energy Consumption Composition in Data Centers

Approximately 45% of data center energy is used for cooling, while 35% goes to servers & storage, and 20% to other infrastructure.

This emphasizes that cooling systems are a critical component in efforts to improve energy efficiency and reduce carbon emissions.

Precision Cooling and Energy Efficiency

Precision cooling is a method that maintains server temperatures within a specific range to meet service level agreements (SLA). This technology is now more flexible because modern servers can operate optimally up to 27°C, compared to the previous 18–19°C requirement. This flexibility allows energy and emission reductions without compromising performance.

Cooling Technology Innovations

Some key innovations adopted to enhance efficiency and sustainability include:

• Liquid Cooling: Directly cools server components, more efficient than cooling the entire room air.
• Evaporative Cooling: Uses the evaporation process to lower temperatures with less energy.
• Direct Cooling: Focuses on specific areas rather than the entire room to reduce cooling capacity.

These strategies emphasize protecting servers rather than the room, allowing lower cooling capacity and more energy-efficient operation.

Certified Human Resources and Optimal Operations

The success of a cooling system depends not only on technology but also on certified personnel. Installation or operation by non-certified staff can reduce performance, even in advanced systems.

Certification programs, from ASHRAE or local institutions, are key to maintaining:

• Energy efficiency
• System performance
• Infrastructure longevity

Regulatory and Sustainability Challenges

There are currently no specific regulations governing data center cooling efficiency in Indonesia. However, collaboration between associations and the government—including the Ministry of Energy and Mineral Resources (ESDM)—is underway to establish:

• Energy intensity limits per square meter
• Sustainability standards for cooling systems

These steps are crucial to ensure the industry’s growth aligns with green technology principles, energy efficiency, and environmental friendliness.

Conclusion

This podcast provides deep insights into the complexities of data center cooling in Indonesia:

• Cooling is critical for server performance and reliability.
• The tropical climate demands continuous cooling and innovative strategies.
• Modern precision cooling allows energy efficiency and emission reduction.
• Innovations like liquid, evaporative, and direct cooling reduce cooling capacity.
• Certified personnel and proper operations support system optimization.
• Regulations and government collaboration are needed for long-term sustainability.

By combining advanced technology, certified personnel, and proper regulations, Indonesia can build reliable, efficient, and environmentally friendly data centers to support sustainable digital growth.

The post Data Center Cooling in Indonesia: Addressing Tropical Climate Challenges and Innovative Technology appeared first on Nusantara Academy.

The podcast “Standards, Challenges, and Opportunities in Optimizing Green Data Centers in Indonesia,” produced by Nusantara Data Center Academy, discusses the steps toward establishing a national Green Data Center standard. The episode is hosted by Sari Oktaviani and features two prominent figures:

• Hendra Surya Kusuma – Co-founder and Chairperson of ID Pro (Indonesia Data Center Provider Organization), Country Director of Faset Indonesia, and CEO of Data Sinergi Utama Jaya, the first Tier 3 certified data center in Indonesia.
• Gatot Prawiro – Chairperson of the Industry Working Group of Mas Key and Chief Business Development Officer of Max Power Group, with over 36 years of experience in the energy sector.

The Pillars of Green Data Centers in Indonesia

Since 2019, BSN (National Standardization Agency), Kominfo, and industry stakeholders have issued SNI 8799, the first national standard for Green Data Centers. This standard focuses on four main pillars:

1. Energy and carbon emission management, which covers how energy consumption is monitored and reduced.
2. Energy efficiency, involving people, processes, and technology to reduce electricity usage.
3. Water efficiency, through guidelines for careful and measured water use.
4. Environmental impact, an often overlooked but critical aspect for long term sustainability.

Hendra emphasized that although this standard already exists, the majority of data centers in Indonesia still rely on electricity from coal fired power plants because it is considered the cheapest option.

Industry and Regulatory Collaboration

Standardization efforts cannot stand alone. Collaboration between ID Pro, Maskey, Kominfo, and BSN continues to develop a certification scheme known as Gerindasan with three levels: Basic, Natural, and Advanced.

Currently, many data center providers in Indonesia still refer to international standards such as Green Mark Singapore or Tier Classification. However, these standards focus more on mechanical, electrical, and cooling infrastructure. Meanwhile, the aspects of energy consumption and environmental impact, which are crucial to Indonesia’s context, have not been fully accommodated.

Technological Innovations Already Applied

Several industry players have begun adopting environmentally friendly technologies, including:

• A 35 hectare solar farm combined with biomass, producing around 40 MW of clean energy.
• Gas engines with absorption chillers for more efficient cooling.
• Direct cooling in server racks and trials of liquid immersion cooling for processors.
• Machine learning and predictive analytics to automatically shut down unused equipment.

These innovations help reduce Power Usage Effectiveness (PUE) and lower the carbon footprint. However, technical challenges such as permits for gas engine installation and limited space remain obstacles.

Challenges in Adopting Green Data Centers

Although the technology is available, the implementation of Green Data Centers still faces several challenges. Among them are:

• The absence of fiscal incentives such as those provided in the United States or Johor Bahru, Malaysia.
• High electricity costs, which can account for up to 76 % of total operating expenses.
• Dependence on PLN, whose electricity supply is still dominated by coal, limiting access to renewable energy.
• Import taxes and complex regulations for high tech equipment.
• Operators’ main focus on uptime and reliability, while energy management has not yet become a priority.

Without government support in the form of incentives, many operators will struggle to fully adopt green technologies.

Renewable Energy and the Future

Technically, data centers can achieve 100 % reliance on renewable energy. Several options that have already been tested include:

• Large scale solar farms combined with biomass.
• Mini hydro plants with capacities ranging from 750 kW to 35 MW.
• Cogeneration systems capable of achieving up to 95 percent efficiency.
• Small Modular Nuclear Reactors (SMRs) capable of generating 10 to 20 MW of stable electricity for six years without refueling.

These technologies have the potential to become part of Indonesia’s future energy mix, although cost and regulatory challenges must still be addressed.

The Long Road to Green Data Centers

Hendra emphasized that data centers are the backbone of Indonesia’s digital economy. Without clear national standards, the risks of inefficiency and fragmentation will only increase.

Gatot added that the government must be present not only as a regulator but also as a partner. Mechanisms of reward and punishment, fiscal incentives, and stronger regulations are needed so that the industry will not hesitate to invest in green solutions.

Conclusion: Time to Get Serious about Green Standards

Data centers are the backbone of our digital economy. Without clear green standards, the risks of inefficiency and environmental impact will only grow.

The podcast highlights several key recommendations:

1. The government needs to strengthen regulations, including revising PP 82/2012 and PP 71/2019.
2. Provide fiscal incentives such as tax holidays or tax credits.
3. Encourage the implementation of reward and punishment mechanisms for adopting green standards.
4. Enhance collaboration between government, industry, and data center associations.

Green Data Centers are not only about energy efficiency but also about the sustainable future of Indonesia’s digital economy. With regulatory support and innovation, Indonesia has the potential to become a leader in Green Data Centers in Southeast Asia.

The post Indonesia’s Path to Green Data Centers: Standards, Challenges, and Opportunities appeared first on Nusantara Academy.

Indonesia’s data center industry stands at a critical crossroads. On one side, the demand for digital services is skyrocketing, fueled by nationwide digital transformation, the rapid expansion of cloud adoption, the rise of artificial intelligence (AI), and the upcoming 5G rollout. On the other side, the massive energy consumption required to power this growth poses significant sustainability and environmental challenges.

This was the central theme of the Clean Energy Podcast, part of the Indonesia Conference (IC) 2023, organized by the Indonesian Society for Energy Conservation and Efficiency. The episode, hosted by Serep Oktaviani, featured a deep discussion on the standardization and transition toward Green Data Centers with two industry leaders:

• Hendra Surya Kusuma – Co-founder and Chairperson of ID Pro (Indonesia Data Center Provider Organization), Country Director of Faset Indonesia, and CEO of Data Sinergi Utama Jaya, the first Tier 3 certified data center in Indonesia.
• Gatot Prawiro – Chairperson of the Industry Working Group of Mas Key and Chief Business Development Officer of Max Power Group, with over 36 years of experience in the energy sector.

ID Pro: Strengthening Indonesia’s Data Center Foundation

ID Pro was established in June 2016 to address three major challenges in the Indonesian data center industry:

1. Negative international campaigns suggesting Indonesia lacked qualified data centers, discouraging the hosting of critical applications locally.
2. Unverified certification claims by providers without independent audits, creating market distrust.
3. Government misclassification of simple server rooms as professional data centers.

Through partnerships with Kominfo (Ministry of Communication and Informatics) and BSN (National Standardization Agency), ID Pro played a key role in the creation of SNI 8799, the Indonesian National Standard for data centers. This standard was later referenced in Presidential Regulation No. 95/2018 on Electronic-Based Government Systems (SPBE).

ID Pro’s growth has been significant:

• 2016: 6 members with ~32 MW capacity.
• 2023: over 260 MW capacity, projected to reach 300 MW soon.

The association is now working on a Green Data Center White Paper, which could evolve into a new national standard.

Mas Key: Efficiency as the “First Fuel”

Meanwhile, Mas Key plays an important role in driving energy efficiency across industries. According to Gatot Prawiro, the guiding principle is simple: “Efficiency is the first fuel.” Every kilowatt saved is as valuable as a kilowatt produced.

Mas Key’s initiatives focus on:

• Greening data centers, especially optimizing power and cooling systems.
• Industrial energy audits to identify and eliminate inefficiencies.
• Energy reuse, such as converting exhaust heat into steam for paper production, or turning waste heat into cooling energy.

Gatot emphasized that sustainability is not a cost burden but a business opportunity. As he put it: “Green is green.”

Energy Consumption Trends and Future Projections 

Indonesia’s current data center capacity is estimated at:

• 260 MW from ID Pro members.
• ~330 MW including global players like Amazon, Microsoft, and Google.

However, projections from industry experts and PLN (Indonesia’s state electricity company) suggest demand could surge to 1.7 GW (1700 MW) within 5–7 years.

Key drivers include:

1. AI and Machine Learning – which can consume up to 25,000 watts per rack, far higher than the traditional average of ~2,200 watts.
2. 5G deployment in 2025 – expected to accelerate data generation and cloud adoption.

This rapid growth highlights the urgency of adopting green strategies before energy demand becomes unsustainable.

Defining a Green Data Center

According to Hendra Surya Kusuma, a Green Data Center goes beyond efficiency alone. It requires balancing operational effectiveness with environmental responsibility, measured across four dimensions:

1. Energy Supply – the carbon footprint of electricity sources.
2. Energy Efficiency – optimized Power Usage Effectiveness (PUE).
3. Water Utilization Effectiveness – efficient management of water resources.
4. Environmental Impact – broader ecological consequences beyond energy and water.

He pointed to Singapore as a cautionary example, where data centers already consume 5% of national electricity capacity, forcing the government to restrict new developments until greener solutions are found.

Practical Green Strategies for Data Centers

Both experts highlighted practical steps already being explored in Indonesia:

• Targeted cooling (zone cooling) instead of cooling entire rooms.
• Allowing higher ambient temperatures in server rooms to reduce cooling demand.
• IoT-based energy monitoring, enabling transparency and real-time data.
• Purchasing green energy certificates from PLN, a growing trend among large operators.

Still, many data centers built before 2016 lack smart monitoring systems, relying on manual measurements. Awareness of carbon emissions also remains low, despite the government’s plans to introduce a carbon tax.

Industry Progress and Global Client Demands

Within ID Pro, almost all members are now engaged in sustainability discussions. Focus areas include:

• IoT and machine learning dashboards for integrated monitoring of electrical, mechanical, and cooling systems.
• Automation to reduce downtime, since 78% of outages are human-related.
• Meeting international client requirements, especially from Europe and North America, where “green compliance” is often mandatory in Requests for Proposals (RFPs).

Yet, full adoption of Green Data Center standards is still evolving. Many providers rely partly on green energy certificates to satisfy client expectations.

Energy Accounting: A New Paradigm

Gatot introduced the concept of energy accounting, comparable to financial accounting but focused on energy use. While new for many operators, it offers several benefits:

• Identifying inefficiencies and cost-saving opportunities.
• Supporting internal corporate policies.
• Providing regulators with accurate data to craft realistic policies.

Currently, most Indonesian data centers still rely heavily on coal-based power, underlining the urgent need for regulatory frameworks that enable a transition toward renewable energy.

Conclusion: The Long Road to Green Data Centers

The discussion made clear that Indonesia has the capacity for digital growth but must urgently address sustainability challenges.

Key takeaways include:

• Rapid growth: from 32 MW in 2016 to 260 MW+ in 2023.
• Energy risk: projected demand of 1.7 GW within 5–7 years.
• Green standards: a new national framework is essential beyond SNI 8799.
• Practical solutions: targeted cooling, IoT monitoring, and green energy certificates.
• Collaboration: industry-government partnership is the only way to accelerate adoption.

With clear standards, regulatory support, and industry-wide adoption of green technologies, Indonesia has the potential to become a regional leader in sustainable data center development—driving digital transformation while safeguarding environmental sustainability.

The post Indonesia’s Journey Toward Green Data Centers: Balancing Digital Growth and Sustainability appeared first on Nusantara Academy.

Indonesia’s banking industry is undergoing a rapid digital transformation. This shift is evident not only in the widespread use of mobile banking and the surge of electronic transactions but also in the growing reliance on data centers as the backbone of financial operations. Without secure, reliable, and sustainable data centers, modern banking services would be highly vulnerable to disruption.

A recent discussion on “Data Center Security and Sustainability in Indonesian Banking” highlighted several pressing issues: physical security and site selection, cybersecurity challenges, and the urgent shortage of skilled professionals in this field.

1. Ideal Locations and Physical Security

As an archipelago prone to natural disasters such as earthquakes, floods, and urban fire hazards, Indonesia faces a dilemma in choosing safe yet practical locations for banking data centers.

• Jakarta and its surroundings remain the preferred location due to stronger infrastructure—stable electricity supply, extensive network connectivity, and better communication systems. However, Jakarta carries a significant earthquake risk and high infrastructure centralization, which could lead to systemic disruption in case of a large-scale disaster.
• Kalimantan is safer from earthquakes but still lacks sufficient infrastructure, making it less suitable for data center deployment at this stage.

Most banks build and own their own earthquake-resistant facilities. These are typically low-rise buildings, designed with resilience as the top priority.

For example, BCA operates two data centers within 30 km of each other in Jakarta, plus a disaster recovery site in Surabaya. This design ensures operational continuity even if one center fails. The ultimate commitment is to maintain 24/7 transaction availability, ensuring zero disruption to customers.

2. Business Continuity Planning

In banking, even a few seconds of downtime can translate into significant financial and reputational losses. This makes business continuity planning (BCP) a top priority.

While much of Indonesia’s financial infrastructure—such as Bank Indonesia and other major institutions—is centralized in Jakarta, banks still aim to separate data center sites as far apart as possible to reduce systemic risks.

Continuity planning includes more than just site distance. It also involves backup systems, disaster recovery procedures, and rapid activation protocols to safeguard core services and customer trust.

3. Cybersecurity: The Invisible Enemy

Beyond physical risks, banks face increasingly sophisticated cyber threats. Securing digital infrastructure requires a multi-layered approach—covering data center design, access control, employee devices, and external vendors.

Top Three Cyber Threats:

1. Ransomware – Attackers encrypt data and demand ransom for release.
2. Data Theft – Information is stolen without destroying systems, often with long-term implications.
3. Denial of Service (DoS) Attacks – Overwhelming systems with traffic, rendering services inaccessible.

Additional Threats:

• Phishing emails, which surged during the COVID-19 pandemic.
• Internal virus outbreaks spreading through local networks.
• Leaks from vendors or careless employee behavior on personal devices.

Key Protection Strategies:

• Early warning systems to detect suspicious keywords in communications.
• Regular review of access and data usage policies.
• Staff awareness programs on data confidentiality.
• Deployment of encryption, anti-virus software, and multi-factor authentication.
• Independent security audits and penetration testing to identify vulnerabilities objectively.

Currently, cooperation with government agencies and law enforcement is mostly reactive, initiated only after fraud or crime occurs. The industry must move toward proactive partnerships to prevent attacks before they materialize.

4. Talent Shortage: The Human Resource Challenge

Technology is only as strong as the people who manage it. One of Indonesia’s most critical challenges lies in the severe shortage of qualified data center professionals.

Unlike software development or other IT disciplines, data center management lacks formal academic programs in local universities. Most professionals acquire expertise on the job rather than through structured education.

Yet, data center engineers need a rare combination of skills:

• Electrical engineering (power supply, UPS, generators).
• Mechanical systems (cooling, fire suppression).
• IT and networking (servers, security, storage).
• Business acumen (understanding how downtime directly translates into financial losses).

Large banks like BCA offer internal training, but the focus is often on networking and business rather than core data center competencies.

Given that Indonesia’s data center market is projected to grow by 11.4% annually, this talent gap will only widen. Without targeted investment in education and training, Indonesia risks overreliance on foreign expertise.

Needed Solutions:

• Developing formal university curricula for data center engineering.
• Establishing local training centers with Bahasa Indonesia-based modules.
• Industry–government–academia collaboration to build a local talent pipeline.
• Raising awareness that data center engineering is a promising career, not just a behind-the-scenes job.

5. Future Directions: Security and Talent as Strategic Investments

The discussion concluded with several forward-looking recommendations emphasizing that data centers are not just technological assets but also strategic drivers of business and national economic resilience.

Key Priorities for the Future:

1. Integrating security at the design stage of systems and applications, not as an afterthought.
2. Strengthening infrastructure coordination, especially electricity and telecommunications, to prevent disruptions during major government projects.
3. Expanding and professionalizing data center teams to keep pace with rising data volumes and transaction complexity.
4. Comprehensive disaster recovery planning that addresses both physical risks and cyber threats.
5. Long-term investment in talent development, including education, training, and certification.

 

Conclusion

Data centers are the digital heartbeat of Indonesia’s banking industry. Their reliability and security determine not only customer trust but also the overall stability of the financial system.

Yet, challenges remain. Jakarta’s earthquake risks, increasingly complex cyberattacks, and a lack of skilled professionals present serious vulnerabilities. Solving these issues will require investment in both infrastructure and human capital.

If addressed with urgency, Indonesia can not only safeguard its banking ecosystem but also position itself as a competitive hub in the regional data center industry.

Careers in data center management may be underrecognized today, but the future demand is undeniable. As digital transformation accelerates, banks, government, and academia must collaborate to cultivate the next generation of Indonesian data center talent—ensuring the security, sustainability, and competitiveness of digital banking services for years to come.

The post Data Centers in Indonesian Banking: Security, Sustainability, and Talent Readiness appeared first on Nusantara Academy.

Indonesia’s banking industry has undergone a profound transformation over the past few decades. What once relied heavily on in-person interactions with tellers at branch offices has now shifted to digital-first services. Today, customers can transfer funds, pay bills, invest, or even apply for loans directly from their smartphones. This major shift would not be possible without data centers, the core infrastructure enabling modern financial services.

A recent episode of the Nusantara Data Center Academy podcast highlighted this topic in detail. Hosted by Oktaviani, the discussion featured two industry veterans: Hermawan Tendean, Commissioner of i4t and former Senior Executive President of IT at Bank BCA, and Billy Guan, Vice President of IT Service Operation at Bank Permata. Together, they unpacked the evolution of data centers in Indonesian banking, the regulatory landscape, strategic decision-making, and the future of banking technology.

From Small Rooms to Nationwide Infrastructure

In the late 1980s, Indonesian banks began transitioning from manual systems to computer-based operations. At that time, data centers were nothing more than small rooms equipped with basic cooling and a handful of servers, used primarily for internal processes such as customer transaction recording and account management.

Over the years, however, as digital banking services grew, the demand for larger capacity and higher reliability became unavoidable. Leading banks now operate multi-data center architectures, often in an active-active configuration, where one data center can seamlessly take over if another experiences disruption. This ensures high availability, providing uninterrupted digital banking services and meeting customer expectations for 24/7 reliability.

This evolution represents more than just technological advancement—it reflects the growing need for speed, convenience, and trust in the financial sector.

Operational Stability, Security, and Regulatory Compliance

For banks, data centers are not just technical facilities; they are the operational heart of the institution. Even the smallest disruption can affect millions of customers.

Experts highlight three critical pillars:

1. Operational stability – Modern data centers must feature redundant infrastructure, fire protection systems, and reliable backup power to ensure zero downtime.
2. Data security – Both physical security (restricted access, 24/7 monitoring) and cybersecurity are essential to protect against internal breaches and external attacks.
3. Regulatory compliance – Indonesian regulators mandate strict oversight, requiring banks to report data center details annually, enforce data lifecycle management (including secure disposal), and maintain privacy safeguards for customer information.

In this context, innovation in banking IT must always be balanced with compliance and protection, ensuring that customer trust remains uncompromised.

Geographic Concentration and Its Risks

Due to infrastructure realities, most banking data centers in Indonesia are concentrated in Jakarta and Bali, where stable electricity, telecommunications, and logistics are more readily available.

While this concentration is practical, it also introduces major risks:

• Disaster vulnerability – Jakarta is prone to flooding and earthquakes. A large-scale disruption could have nationwide financial impacts.
• Unequal data distribution – With Indonesia’s vast geography, a Jakarta-centric model creates challenges in ensuring accessibility and resiliency for customers across the archipelago.

Geographic diversification of data centers, including in Sumatra and Sulawesi, will be essential to reduce systemic risk and strengthen resilience at the national level.

Build or Colocate? A Strategic Dilemma

One of the most significant decisions banks must make is whether to build their own data centers or use third-party colocation services.

• Building in-house allows banks full control, greater flexibility, and stronger security. However, it demands significant capital investment and operational expertise.
• Colocation offers lower upfront costs and faster deployment, but it may limit operational agility and raise concerns about data security.

The choice is not purely financial; it reflects a bank’s long-term vision for technology adoption, risk management, and customer service.

Sustainability and Energy Efficiency

Data centers are among the most energy-intensive infrastructures globally, making sustainability a rising priority in banking operations.

Indonesian banks are taking steps to address this challenge through:

• Cooling optimization to reduce excessive power consumption.
• Collaboration with PLN, the state electricity provider, to ensure reliable and high-quality power supply.
• Regular infrastructure upgrades to modern, energy-efficient systems that align with global carbon-reduction targets.

Sustainability efforts serve not only to manage operational costs but also to position banks as responsible contributors to environmental goals.

Disaster Preparedness and Business Continuity

As a disaster-prone nation, Indonesia faces risks such as earthquakes, tsunamis, and volcanic eruptions. For banks, this makes business continuity planning and disaster recovery strategies non-negotiable.

• Redundant systems and geographically diverse facilities must be in place to guarantee uninterrupted services.
• Regulators require banks to conduct regular stress tests and scenario drills to ensure preparedness during emergencies.

These measures highlight the strategic importance of resilience, as banking operations are directly tied to national economic stability.

Emerging Trends Shaping the Future

Looking forward, Indonesian banks are beginning to embrace new technological models for their data centers, including:

• Cloud integration for greater scalability and agility.
• Automation to improve operational efficiency and reduce human error.
• Hybrid data center models, combining physical infrastructure with cloud-based solutions.
• Advanced cybersecurity systems to defend against increasingly sophisticated threats.

These innovations will help banks remain competitive, enhance customer experience, and align with both regulatory and market demands.

Conclusion: Data Centers as the Foundation of Banking’s Digital Era

The journey of data centers in Indonesia’s banking sector mirrors the nation’s broader digital transformation. From modest computer rooms with limited functions, they have grown into highly sophisticated, secure, and resilient infrastructures that keep the country’s financial system running 24/7.

The road ahead will require banks to balance innovation with compliance, centralization with diversification, and efficiency with sustainability. By investing in robust disaster recovery, embracing emerging technologies, and strengthening operational security, Indonesian banks can ensure they remain resilient in the face of technological, environmental, and geopolitical challenges.

As emphasized in the Nusantara Data Center Academy podcast, the future of banking will be defined not only by digital services but also by the strength, adaptability, and resilience of the data centers that power them.

The post Data Centers: The Backbone of Indonesia’s Banking Digital Transformation appeared first on Nusantara Academy.

In today’s interconnected world, data centers are the backbone of digital infrastructure. They hold highly sensitive information that must be protected not only through technical measures, but also by meeting legal and regulatory expectations. For data center professionals in Indonesia, “security” is not just firewalls and surveillance cameras. It is also laws, standards, and audits that force consistency, discipline, and proof. Aligning with Indonesia’s regulatory requirements and globally recognized certifications turns good practice into verifiable, repeatable controls that withstand both attacks and scrutiny.

Indonesia’s rapid digital transformation, from e-commerce and fintech to cloud adoption and digital banking, has positioned data centers as critical enablers of trust. However, this rapid growth also makes them prime targets for cyber threats. The government has responded with stricter regulations designed to ensure that sensitive data is properly safeguarded and that providers are accountable. In this landscape, compliance and certifications are not simply formalities; they are critical differentiators.

Recent global incidents underscore the stakes. High-profile data breaches, such as the Equifax breach in the U.S. or the Singtel cyberattack in Singapore, have shown how failures in compliance and inadequate security controls can lead to regulatory fines, lawsuits, and loss of public trust. For Indonesia’s growing digital economy, these examples serve as reminders of why aligning with both national regulations and international standards is vital.

Legal Compliance: The Foundation of Trust

Compliance is no longer optional; it is a legal necessity in Indonesia and beyond. For instance, Law No. 27 of 2022 on Personal Data Protection (PDP Law) requires organizations, including data centers, to implement robust safeguards for personal data and to report breaches within strict timelines. The PDP Law introduced GDPR-style obligations for controllers and processors, including the requirement to notify the regulator and affected data subjects within 72 hours of a breach being identified. Non-compliance can result in administrative sanctions and fines.

Further, Government Regulation No. 71 of 2019 on Electronic Systems and Transactions (PP 71/2019) requires Electronic System Providers (ESPs) to register, maintain audit trails, establish incident response procedures, and report serious incidents to law enforcement and the relevant ministry. Complementing this, BSSN Regulation No. 8 of 2020 sets baseline cybersecurity requirements, guiding how ESPs design policies, safeguards, and monitoring systems.

Meeting these standards often requires advanced monitoring solutions such as Security Information and Event Management (SIEM), which enable rapid detection and reporting of breaches and incidents within the mandated 72-hour window. This suggests that operating or hosting critical digital infrastructure in Indonesia requires both legal compliance and recognized security certifications to demonstrate to regulators, customers, and partners that their controls are both effective and trustworthy.

Certifications as Evidence of Security Excellence

Certifications can help elevate cybersecurity from compliance to a position of leadership. ISO/IEC 27001:2022 provides a structured Information Security Management System (ISMS), focusing on confidentiality, integrity, and availability of data; it is widely adopted across industries. For data centers, ISO/IEC 27001:2022 compliance ensures essential security processes are in place and gives clients assurance of strong cybersecurity practices.

Beyond ISO 27001, other certifications also play key roles. SOC 2 assures the effectiveness of controls, PCI DSS is essential for handling payment data, and Uptime Institute’s Tier certifications confirm the resilience and reliability of infrastructure. Together, these frameworks provide a multi-layered approach to demonstrating operational maturity.

Benefits Beyond Compliance

Certifications bring broader advantages, such as demonstrating a clear commitment to security, enhancing brand reputation, and strengthening stakeholder trust; boosting competitiveness, as ISO/IEC 27001:2022 certified organizations can win deals faster and attract larger clients with reduced friction; and building internal operational efficiency, strengthening security culture, and improving incident prevention.

These benefits extend beyond audits. Many enterprises now require their partners and service providers to maintain certifications as a condition of doing business. In this way, certifications become strategic assets that open doors to new opportunities.

Industry Trends in Indonesia

The Indonesian data center market is expanding rapidly, with global players investing heavily in it. These operators consistently highlight their compliance with both national regulations and international certifications as part of their value proposition. For customers, certifications serve as a shorthand for trustworthiness, helping them make informed choices in a competitive landscape.

There is also a shift from ‘checkbox compliance’ to continuous assurance. Instead of viewing compliance as a one-time exercise, forward-looking organizations are adopting ongoing monitoring and auditing practices. This shift reflects a broader trend in cybersecurity: resilience is not a destination, but a continuous journey.

Synergy of Compliance and Certification

Legal compliance and certifications work hand-in-hand. Research shows organizations integrating ISO/IEC 27001:2022 with the PDP Law can create robust frameworks that satisfy both regulatory and international best-practice standards. While the PDP Law demands specific legal requirements (e.g., consent, breach notification), ISO/IEC 27001:2022 supports those through systematic risk management and continuous improvement.

Building Talent for a Secure Ecosystem

Another important aspect of compliance and certifications is the demand they create for skilled professionals. Data centers increasingly require compliance officers, auditors, and ISMS managers who understand both regulatory obligations and technical frameworks. This demand contributes to talent capacity building in Indonesia’s digital infrastructure sector and opens opportunities for professionals looking to specialize in cybersecurity and compliance.

Conclusion

Compliance provides a baseline for legal and regulatory safety. Certifications such as ISO/IEC 27001:2022 build on that baseline, turning it into a strategic advantage that demonstrates resilience and builds trust. When combined, they empower data centers to lead in cybersecurity while aligning with regulations. For Indonesia’s growing digital economy, this synergy ensures that critical infrastructure remains both secure and trustworthy.
