"Sesuai dengan Tujuan Pembangunan Berkelanjutan nomor tujuh yang dicanangkan oleh Perserikatan Bangsa-bangsa bahwa pengentasan kemiskinan dan kebodohan dapat dilakukan dengan memastikan kualitas akses pada energi yang dapat diandalkan, berkelanjutan, dan modern untuk semua. Namun, kualitas akses listrik di Indonesia masih tidak merata antara satu daerah dengan yang lainnya. Sistem perdagangan energi secara peer-to-peer dengan menggunakan teknologi blockchain merupakan sebuah inovasi alternatif dalam menyediakan akses terhadap energi berkelanjutan. Untuk itu, prototipe di bangun pada Kecamatan Gumelar, Jawa Tengah. Tujuan penelitian ini adalah untuk menganalisis persepsi stakeholders, menganalisis potensi dampak ekonomi, mengevaluasi potensi pengurangan emisi CO2 dan menyusun strategi kebijakan berkelanjutan dari penerapan inovasi tersebut diatas. Penelitian ini melibatkan beberapa metode analisis antara lain matriks SWOT, IFE/EFE, QSPM dan analisis kelayakan finansial. Hasil menunjukkan bahwa inovasi bisa tumbuh dan berkembang dengan memenuhi berbagai syarat yang ada, layak secara finansial, mengurangi emisi CO2 secara signifikan. Dua belas prioritas strategi kebijakan berkelanjutan telah disusun untuk membantu peningkatan pemerataan kualitas akses listrik di Indonesia.

In accordance with Sustainable Development Goal number seven proclaimed by the United Nations, eradicating poverty and ignorance can be done by ensuring quality access to reliable, sustainable and modern energy for all. However, the quality of electricity access in Indonesia is still uneven between one region and another. A peer-to-peer energy trading system using blockchain technology is an alternative innovation in providing access to sustainable energy. For this reason, a prototype was built in Gumelar District, Central Java. The aim of this research is to analyze stakeholders’ perceptions, evaluate the potential economic impact, analyze the potential for reducing CO2 emissions and develop sustainable policy strategies from implementing the innovations mentioned above. This research involves several analysis methods, including the SWOT matrix, IFE/EFE, QSPM and financial feasibility analysis. The results show that innovation can grow and develop by fulfilling various existing requirements, is financially feasible, and reduces CO2 emissions significantly. Twelve sustainable policy strategy priorities have been developed to help increase equitable quality access to electricity in Indonesia."

"Drawing on political science, economics, philosophy, theology, social anthropology, history, management studies, law, and other subject areas, In Search of Good Energy Policy brings together leading academics from across the social sciences and humanities to offer an innovative look at why science and technology, and the type of quantification they champion, cannot alone meet the needs of energy policy making in the future. Featuring world-class researchers from the University of Cambridge and other leading universities around the world, this innovative book presents an interdisciplinary dialogue in which scientists and practitioners reach across institutional divides to offer their perspectives on the relevance of multi-disciplinary research for 'real world' application. This work should be read by anyone interested in understanding how multidisciplinary research and collaboration is essential to crafting good energy policy."

ABSTRACTInterdisciplinary in its approach and global in its perspective, Energy Systems and Sustainability: Power for a Sustainable Future, Second Edition, provides a contemporary exploration of the economic, social, environmental, and policy issues raised by current systems of energy use. Emphasizing the important issue of sustainability, it analyzes the historical evolution of the world's energy systems, the principles underlying their use, and their present status and future prospects. Beginning with a survey of basic energy concepts, the book describes the magnitude and patterns of human energy needs at various levels. It moves on to an overview of the fossil and nuclear-fuelled energy that, together with hydroelectric power and traditional biofuels, supply most of the world's commercial energy needs. Sections on economics describe the basic methods through which the monetary costs of energy are calculated, also considering the "external" costs of energy production. Finally, the book looks at the sustainability issues associated with both fossil- and nuclear-fuel use--and considers the technological advancements and social developments that might solve these problems. Providing a truly interdisciplinary approach, Energy Systems and Sustainability: Power for a Sustainable Future, Second Edition, is ideal for undergraduate engineering students and undergraduates studying policy making.

"Penelitian berfokus pada analisis penerapan double stage absorption system untuk meningkatkan kinerja Pembangkit Listrik Tenaga Panas Bumi Kamojang Unit V. Panas yang diambil berasal dari abandoned well sekitar Kamojang yang masih memiliki tekanan 400 kPa. Terdapat beberapa analisis yang dilakukan yaitu analisis exergy pada kondisi operasi, optimasi efisiensi exergy, optimasi biaya dan optimasi multi objektif. Perhitungan dilakukan dengan program Matlab, dan optimasi optimtool. Tekanan operasi saat ini menghasilkan efisiensi exergy 44.93. Optimasi single objektif sistem gabungan menghasilkan efisiensi exergy sebesar 52.66 , biaya 3558400. Optimasi single objektif biaya menghasilkan exergy 51.55 dengan biaya 2514000 dan Optimasi objektif menghasilkan efisiensi 48.64 dengan biaya 2913700 dengan parameter optimum tekanan scrubber 782.64 kPa, beda temperatur air pendingin 3.12°C, temperatur evaporator 7.6°C, temperatur desorber 120.08°C, temperatur condenser 44.9°C, temperatur absorber 43.79°C.
