Abstract

Pembangkit listrik energi terbarukan (ET) dapat mengurangi penggunaan pembangkit listrik berbahan bakar fossil yang merusak lingkungan terkait dengan emisi CO2. Photovoltaic (PV) adalah suatu alat yang dapat mengubah energi surya (foton) menjadi listrik arus searah yang merupakan salah satu komponen dalam Pusat Listrik Tenaga Surya (PLTS). Karakteristik tekno ekonomi PV sangat mempengaruhi Levelized Cost of Energy (LCOE) dari PLTS. Penelitian ini bertujuan untuk menganalisis perkembangan teknologi PV dan pemanfaatannya di Indonesia. Metode tinjauan Pustaka yang komprehensif dilakukan dalam penelitian ini. Dari hasil diskusi dan pembahasan disimpulkan bahwa teknologi PV jenis monokristalin memiliki tren pemakaian yang relatif tinggi karena effisiensi/kinerja relatif tinggi, kemudahan fabrikasi, sifat ramah lingkungan, & kehandalan terhadap kondisi lingkungan yang ekstrim (umur operasional lama). Potensi energi surya terbesar di Indonesia terdapat di sekitar wilayah Nusa Tenggara Timur dengan nilai direct normal irradiation sebesar 5 kWh/m2. PLTS berpotensi untuk dibangun di luar Jawa Bali Sumatera mengacu pada tingginya LCOE setempat sehingga nilai feed in tariff yang digunakan dalam kontrak jual beli listrik dapat bersaing dengan nilai LCOE PLTS.

Abstract

Lapangan panas bumi Jailolo terletak di wilayah Halmahera, Maluku Utara. Lapangan panas bumi ini direncanakan untuk dikembangkan sebagai pemenuhan kebutuhan energy listrik di wilayah Indonesia Timur. Sebelum dilakukan pengembangan lapangan panas bumi maka perlu dilakukan perhitungan potensi cadangan panas bumi. Dalam perhitungan potensi cadangan panas bumi menggunakan metode volumetric dan metode monte carlo yang merujuk pada SNI No. 13-6169-1999, karena lapangan panas bumi Jailolo belum ada sumur eksplorasi dan belum adanya data produksi sumur. Parameter yang digunakan dalam perhitungan diperoleh dari data hasil kegiatan survei pendahuluan dan geotermometer berupa data ketebalan, luas serta temperatur reservoir. Sedangkan parameter lainnya yang belum diperoleh dari kegiatan survei pendahuluan didasarkan pada SNI No. 13-6482-2000. Hasil perhitungan potensi cadangan terduga panas bumi menggunakan metode volumetrik dengan luas area prospek sekitar 6 km², ketebalan reservoir sekiar 1500 m dari permukaan, dan temperatur reservoir 200 – 220 °C diperoleh sebesar 98.38 MWe, sedangkan hasil perhitungan metode monte carlo diperoleh potensi cadangan terduga sebesar P10 = 14.88 MW, P50 = 29.44 MW dan P90 = 50.26 MW. Potensi Panas Bumi Geothermal WKP Jailolo berpotensi untuk dikembangkan dengan kapasitas 10 MW, dengan dimulai pemboran sumur eksplorasi di area Upflow Manjanga. Pembangkitan yang layak adalah dengan harga listrik USD 13.5 cent/Kwh, IRR >11%, NPV positive, Pay Out Time pada tahun ke 11 – 12 setelah produksi, dan Profitability Indeks sudah (lebih dari satu). Harga listrik tersebut masih dibawah USD 15.90 cent/kWh, BPP Regional

Abstract

Indonesia is a blessed country with abundant renewable resources and the potential to manufacture up to 419 GWh of clean electricity for its people. The government plays a crucial role in shaping and nurturing the proper environment to support RE adoption and transition toward a sustainable economy. Various tools and dimensions are available to observe the government's role in accelerating RE adoption. However, studies show that the metrics used to examine Indonesia’s government regarding RE adoption are lacking. This provides an opportunity to improve the metrics by referring to countries worldwide that show success in the particular research field. The current study aims to address the challenge by presenting a literature review of studies on the government's role in RE adoption and extracting insight to develop improved metrics for examining Indonesia’s government's role in RE adoption. Furthermore, we use data mining to visualize the research map of the current topic to provide an understanding of which areas are underexplored. Thus, future studies can refer to the results to contribute further to the literature.

Abstract

Silica deposit powder from geothermal waste often becomes material waste that difficult to utilize and re-use. The characterization of silica deposit powder has a significant part in understanding its structure, composition, and potential application. Using silica as a filler system in additive manufacturing is one of the processes that can utilize silica deposit powder. This material has the potential to be used to create prototype product with stereolithography resin for 3D printing. The present study discusses the ability to mix specimens of silica (size 600 microns) and resin with a composition ratio of 1:100. The turbidity test revealed that the specimen mixed in the resin contents showing after 30- and 40-minutes examination from spectrophotometer. In the hardness test, by adding filler materials, it is shown that the filler decreased the hardness more than 46%. This research also successfully examines the most effective particle sizes to the length of time required for the mixing and curing processes in order to obtain the most optimal results.
