Abstract

PLTS adalah suatu teknologi pembangkit yang mengkonversikan foton dari matahari menjadi energi listrik. Faktor penting yang mempengaruhi besarnya foton yang diterima oleh sel surya adalah kebersihan modul surya. Studi pengaruh kebersihan modul surya terhadap unjuk kerja PLTS dilakukan di Denpasar pada bulan Januari sampai Maret, menggunakan dua modul surya yang indentik 14,1 Wp. Modul pertama dibersihkan secara berkala sedangkan modul kedua tidak dibersihkan. Dari studi ini, modul surya dibersihkan menghasilkan daya tertinggi 13,63 Watt. Sedangkan modul surya tidak dibersihkan menghasilkan daya tertinggi sebesar 13,45 Watt, terjadi penurunan sebesar 5,48%. Dari studi ini didapat hasil output dari modul surya yang dibersihkan lebih besar dibandingkan modul surya tidak dibersihkan. Penurunan yang relatif kecil disebabkan oleh pembersihan permukaan modul oleh hujan yang sering terjadi, sehingga secara tidak langsung air hujan membersihkan permukaan modul dari kotoran.

Abstract

The Indonesian National Energy Policy stipulates that renewable energy must contribute 23% of total energy consumption by 2025 and increase to 31% by 2050. Among many resources of the country, biomass is a renewable energy source whit the potential is estimated at 32,654 MW. This article reviews the biomass and electricity generation implementation in Indonesia to get insights on the development of the biomass for power generation of the country. Currently, the biomass electricity generation technology that has been applied in Indonesia includes direct combustion as fuel for coal power plants or co-firing, converted into refuse-derived fuel, gasification, sanitary landfills, and incinerators. From 2011 to 2019, the installed capacity of biomass power plants reached 1857.5 MW or 33.78% of the target of 5500 MW in 2025. The biomass power plants are located in North Sumatra, Jambi, Gorontalo, Riau, West Nusa Tenggara, Papua, Bangka Belitung, North Sulawesi, South Sumatra, East Java, and Jakarta. Considering the high 2025 electricity from biomass target, it is necessary to develop a more intensive biomass power plants because of its large potential, available technology, and its benefits to increase the electrification ratio especially for providing electricity for people in areas not yet covered by the utility network, realizing national energy security, and reducing the use of fossil-based fuels.

Abstract

The central government policy through RUEN targets Bali to use 108 MWp of solar energy by 2025. Bali as a small island of highly developed tourism destinations in Indonesia is considered to have the opportunity to exploit this potential. This research tries to review how the development of PV system in Bali through literature study and field observation. The results of this study indicate that the development of total PV system installed capacity in Bali to date has reached 3.71 MWp or 3.44% of the RUEN target. Based on data managed by the development of PV system in Bali in the last 14 years it increased an average of 265.18 kWp or 7.14% annually. Until now the highest PV system capacity in Bali is in Karangasem Regency which has an installed PV system capacity of 1,106 kWp or 29.79% of the total capacity in Bali. While the lowest capacity is in Jembrana Regency with an installed capacity of 10 kWp or 0.27%. PVsystem in Bali is used in a variety of applications, the largest capacity used for utilities is 58.64%, while the lowest is used for water pumps by 0.55%. Based on the type of PV system, Bali is dominated by an on-grid PV system with an installed capacity of 3,225 kWp or 87%, while the lowest is a hybrid PV system with a capacity of 224 kWp or 6% of the total capacity in Bali.
