The Center for Mineral, Coal, and Geothermal Resources (PSDMBP) of the Geological Agency participated in the series of activities at the Fourteenth Annual ITB International Geothermal Workshop (14th IIGW 2025), which took place from 30 June to 1 July 2025. The workshop was held at the Multipurpose Hall, Center for Research and Community Services (CRCS), 3rd Floor, Bandung Institute of Technology (ITB). 

IIGW is an annual international forum that serves as a platform for knowledge exchange and collaboration in the field of geothermal energy. The event originated from the initiative to revitalize the development of geothermal energy in Indonesia following the World Geothermal Congress (WGC) in Bali in 2010 and the annual meeting of the Indonesian Geothermal Association in Lampung in 2011. Since its inaugural event in 2012 in Bandung, the IIGW has consistently adopted the format of international workshops and congresses such as the Geothermal Resources Council (GRC), the Stanford Geothermal Workshop, and the New Zealand Geothermal Workshop. 

In its fourteenth edition, the event featured plenary & technical sessions as well as a limited exhibition. PSDMBP had the opportunity to occupy one of the exhibition booths during the 14th IIGW series. At the exhibition, PSDMBP showcased data and information derived from geothermal resource potential investigations across Indonesia. The displayed materials covered both indirect utilization potential (for geothermal power generation) and direct utilization (Geothermal Direct Utilization/GDU) for non-electrical purposes such as agriculture, tourism, and industry. This participation is part of PSDMBP’s ongoing efforts to enhance public and stakeholder understanding of the wealth of Indonesia’s geothermal resources and their sustainable development potential. 

During the 14th IIGW, representatives of PSDMBP’s Geothermal Working Team also served as speakers in one of the technical presentation sessions. In this session, Husin Setia Nugraha, representing PSDMBP, delivered a presentation entitled “GDU Potential Management in Indonesia.” He explained that under Law No. 21 of 2014, geothermal energy may be directly utilized for sectors such as tourism, agribusiness, and industry, as well as indirectly for power generation. According to him, geothermal utilization plays a significant role in supporting national energy security and independence, optimizing renewable resources, and reducing greenhouse gas (GHG) emissions.

Husin further emphasized that GDU contributes to the achievement of 8 out of 17 Sustainable Development Goals (SDGs), including SDG 7 (Affordable and Clean Energy), SDG 9 (Industry, Innovation, and Infrastructure), and SDG 13 (Climate Action). Currently, Indonesia ranks second in the world for indirect geothermal utilization but remains at the 74th position for direct utilization, with only 2.3 MWt. Based on 2024 data, the national GDU potential is recorded at 230 MWt, derived from 971 surface manifestations across 201 out of 362 prospect sites. Meanwhile, actual heat extraction reaches 8 MWt from two main locations: Leles (Cianjur Regency) and Cisolok–Cisukarame (Sukabumi Regency). 

Moreover, Husin elaborated on the GDU Potential Management Concept, the Technical Guidelines for GDU Potential and Heat Extraction Calculation, and the Technical Guidelines for GDU Reserve Feasibility Study. He underlined the importance of a comprehensive regulatory framework, institutional capacity strengthening, and the development of systematic technical guidelines as the foundation for sustainable, inclusive, and socially and environmentally beneficial direct geothermal utilization. This aligns with the theme of the 14th IIGW: “Harmonizing Geothermal Energy: Bridging Power Production and Direct Utilization to Empower Communities.” 

Di Ajang Internasional IIGW ke-14, PSDMBP Mendorong Pemanfaatan Langsung Panas Bumi 

Pusat Sumber Daya Mineral, Batubara, dan Panas Bumi (PSDMBP), Badan Geologi berpartisipasi dalam rangkaian kegiatan The Fourteenth Annual ITB International Geothermal Workshop (14th IIGW 2025) yang berlangsung pada tanggal 30 Juni – 1 Juli 2025. Kegiatan tersebut diselenggarakan di Multipurpose Hall, Center for Research and Community Services (CRCS), Lantai 3, Institut Teknologi Bandung (ITB). 

IIGW merupakan forum internasional tahunan yang menjadi ajang pertukaran pengetahuan dan kolaborasi dalam bidang energi panas bumi. Kegiatan ini bermula dari semangat untuk menghidupkan kembali pengembangan panas bumi di Indonesia pasca World Geothermal Congress (WGC) di Bali pada 2010 dan pertemuan tahunan Asosiasi Panas Bumi Indonesia di Lampung pada 2011. Sejak diselenggarakan pertama kali pada 2012 di Bandung, IIGW konsisten mengadopsi format workshop dan kongres internasional seperti Geothermal Resources Council (GRC), Stanford Geothermal Workshop, dan New Zealand Geothermal Workshop. 

Pada penyelenggaraan ke-14 ini, rangkaian acara mencakup sesi pleno dan teknis (Plenary & Technical Sessions) serta Limited Exhibition. PSDMBP mendapat kesempatan untuk mengisi salah satu booth pameran pada rangkaian acara 14th IIGW ini. Dalam pameran tersebut, PSDMBP menampilkan data dan informasi hasil penyelidikan potensi sumber daya panas bumi di Indonesia. Materi yang dipublikasikan meliputi potensi pemanfaatan tidak langsung (untuk pembangkit listrik tenaga panas bumi/PLTP) maupun pemanfaatan langsung (Geothermal Direct Utilization/GDU) untuk keperluan non-listrik seperti pertanian, pariwisata, dan industri. Partisipasi ini merupakan bagian dari upaya PSDMBP untuk meningkatkan pemahaman publik dan pemangku kepentingan terhadap kekayaan sumber daya panas bumi nasional serta potensi pengembangannya secara berkelanjutan. 

Dalam acara 14th IIGW ini, perwakilan PSDMBP dari Tim Kerja Panas Bumi juga menjadi narasumber pada sesi pemaparan. Dalam sesi ini, Husin Setia Nugraha, perwakilan dari PSDMBP, menyampaikan presentasi berjudul “GDU Potential Management in Indonesia”. Beliau menjelaskan bahwa berdasarkan Undang-Undang Nomor 21 Tahun 2014, energi panas bumi dapat dimanfaatkan secara langsung untuk sektor-sektor seperti pariwisata, agribisnis, dan industri, maupun secara tidak langsung untuk pembangkitan listrik. Pemanfaatan panas bumi ini menurutnya, berperan penting dalam mendukung ketahanan dan kemandirian energi nasional, optimalisasi sumber daya terbarukan, dan pengurangan emisi gas rumah kaca (GRK). 

Husin juga menegaskan bahwa GDU berkontribusi terhadap pencapaian 8 dari 17 Tujuan Pembangunan Berkelanjutan (SDGs), antara lain SDG 7 (Energi Bersih dan Terjangkau), SDG 9 (Infrastruktur dan Inovasi), serta SDG 13 (Aksi Iklim). Saat ini, Indonesia menempati peringkat ke-2 dunia dalam pemanfaatan tidak langsung panas bumi, namun masih berada di posisi ke-74 dalam pemanfaatan langsung (2,3 MWt). Berdasarkan data tahun 2024, potensi GDU nasional tercatat sebesar 230 MWt dari 971 manifestasi permukaan di 201 dari 362 lokasi prospek. Sementara itu, ekstraksi panas aktual mencapai 8 MWt dari dua lokasi utama: Leles (Kabupaten Cianjur) dan Cisolok–Cisukarame (Kabupaten Sukabumi). 

Lebih lanjut, Husin memaparkan Konsep Manajemen Potensi GDU, Pedoman Teknis Perhitungan Potensi dan Ekstraksi Panas GDU, serta Pedoman Teknis Studi Kelayakan Cadangan GDU. Ia menekankan pentingnya kerangka regulasi yang komprehensif, penguatan kapasitas kelembagaan, dan penyusunan pedoman teknis yang sistematis sebagai fondasi bagi pengembangan pemanfaatan langsung panas bumi yang berkelanjutan, inklusif, serta berorientasi pada manfaat sosial dan lingkungan. Hal ini sesuai dengan tema IIGW ke-14: “Harmonizing Geothermal Energy: Bridging Power Production and Direct Utilization to Empower Communities.”
