In this journal, an analysis is carried out on the use of livestock manure for use as a biogas power plant in Bali Province. The purpose of this analysis is to find out how much potential electrical energy can be obtained from livestock manure to be developed into a biogas power plant in Bali Province. 8 types of livestock are used as analysis material including cattle, buffalo, goats, horses, sheep, pigs, chickens, and ducks. Livestock population data in Bali Province from 2013 to 2017 listed in the Livestock and Animal Health Statistics book obtained from the Directorate General of Animal Husbandry and Health (Ministry of Agriculture), is used as the base year of analysis to obtain the average value of the population level of each types of farm animals. The analysis of the total potential of electrical energy is done by calculating the total mass of manure per day, the percentage of dry matter content of each type of manure as well as the biogas that can be produced from each type of livestock according to the standards of the Ministry of Agriculture. The total potential of electrical energy can be obtained from the total amount of biogas produced, where 1 m3 of biogas can be converted into electrical energy of 4,7 kWh. Based on the results of the analysis conducted, the total biogas that can be produced is 246.130,81 m3 of biogas, or if it is converted into electrical energy equivalent to 1.156.814,81 kWh/day or around 1,16 GWh/day from the average total population livestock in Bali Province are 19.183.779 livestock.

Beroperasinya PLTS pada penyulang Bangli menyebabkan perubahan performa pada penyulang Bangli terutama pada susut energi dan keandalan penyulang tersebut. Analisis dilakukan dengan load flow simulation pada software ETAP dengan dua kondisi, yaitu penyulang Bangli tanpa dan dengan PLTS untuk mendapatkan hasil susut daya yang selanjutnya digunakan untuk menghitung susut energi. Analisis keandalan dilakukan untuk mendapatkan parameter SAIFI dan SAIDI. Dengan beroperasinya PLTS, nilai susut energi turun sebesar 31,4% dan keandalan penyulang Bangli menghasilkan nilai SAIFI sebesar 9 kali/2 tahun tanpa PLTS dan 4 kali/tahun dengan PLTS, serta nilai SAIDI sebesar 13,9225 jam/tahun tanpa PLTS dan 11,7963 jam/tahun dengan PLTS.

Solar Power Generation System (PLTS) is a power generation system that utilizes sunlight as a renewable energy source and a rooftop as a place for solar panels. This paper presents the results of a study of the potential of a rooftop-based solar power plant in the city of Denpasar by taking a location on the roof of the SD Negeri 5 Pedungan Diponegoro No. 60 Denpasar road using PLTS objects that have been installed. The study was carried out with the help of Heliospoce software. Based on the study, information was obtained that the potential of solar energy was 1912.8 kWh / m2 / year or an average of 5.2 kWh / m2 / day in the city of Denpasar. Sunlight that can produce electricity starts at 07.00 -18.30 WITA. The installed energy potential of PLTS is 3214.6 kWh with an angle corresponding to the roof angle of 30.96o. The result of the potential energy produced will be greater if the installation of PV uses the optimal angle (15o) that is equal to 3407kWh.

PLTS is a power plant that converts sunlight energy into electricity using photovoltaictechnology. Solar panels play an important role in PLTS, because solar panels capture solar radiationthen convert it into electrical energy. The development of solar panel technology is the key to supportthe development of PLTS. This article reviews about the development of solar panels in Indonesia asan important component to support the development of national solar power plants towards a capacityof 6500 MW by 2025. The review will be carried out on various aspects of solar panels including thenational solar panel industry, solar panels available in the domestic market, and the availability ofvarious panels. Data is obtained from the national panel industry, the PLTS project, the PLTS userassociation, the national EPC, the Ministry of Energy and Mineral Resources, and the national solarpanel vendor. The survey result shows there are 241 panels, both local and foreign production. Panelcapacities vary from 5 Watt to 500 Watt and panel voltages are available from 12 Volt, 24 Volt and 48Volt. Based on the survey, it is also obtained the average of Rp/Wp is Rp.18,853/Wp and the averageof W/m2 is 159,46 W/m2. Increasing solar panel production can be done by providing incentives tosolar panel producers in the form of product purchase guarantees and incentives to develop newfactories. Information regarding the current status of solar panels in Indonesia is expected to be aquick reference for people or institutions that need it, and can be used as an introduction to researchand application of PLTS in Indonesia.

The utilization of renewable energy can be a solution to support the supply of electricalenergy, one of which is the use of solar energy with rooftop solar panels. In this study, the roofof the Graha Sewaka Dharma Building was used as a location for the design of rooftop solarpower plants to be able to help with electrical energy needs and support government programsin developing the use of solar energy. The total roof area of Graha Sewaka Dharma Building is1,616.37 m2. This design uses a battery-free On-grid PLTS system using a Solaria PowerXT-400R-PM solar module with a capacity of 400 Wp and a Ginlong Solis S5-GC36K-LV inverterwith a capacity of 36 kW. This design will calculate the capacity of solar modules that can beinstalled and the electrical energy produced with the limitation of the roof area and load profile inthe Graha Sewaka Dharma Building. Based on the results of the study, the capacity of therooftop PLTS installed in the Graha Sewaka Dharma Building is 188.8 kWp with a total of 472solar module units and 6 inverter units. The energy output produced per year (energy yield) is306,2 MWh/year. The investment feasibility study using the methods Net Present Value,Profitability Index, and Discounted Payback Period shows that this design investment isfeasible. Further research is recommended to study the impact of reducing carbon emissions onthe use of the PV grid.

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.

In general the average rice harvest in Indonesia is three times in one year with a rice age of 115-120 days. Subak is an organization owned by farmers in Bali that specifically regulates traditional rice field irrigation systems. Subak Semaagung every year there is a shortage of water on agricultural land. Subak area of approximately 55 hectares consisting of six groups of farmers called "tempek". Agricultural water supplied to each tempek interchangeably because the water supply is very limited, so any tempek can only grow rice once in 2 years. The situation is very difficult for farmers to maintain their own rice fields with a limited water supply, so that the fields in the Subak has been largely abandoned. Previously, the Ministry of Agriculture has provided assistance in the form of diesel-powered irrigation pump system, but the diesel-powered water pumping systems are only used for 1 year because it requires a very complicated way of operational and fuel costs are enormous. This research will be designed water pump system Solar Power Plant (PLTS) for more effective than previous diesel pump. From the discussion and analysis has been done that with an area of 300 m2 can be mounted solar panels monokristaline 52.14 kW with a maximum capacity of solar modules totaling 158 units, inverter 33 kW two units, and Submersible pumps SP 60-9 two units. So that the result of the calculation of water that can be lifted inthe dry season every day is 1.275.000/liters/day. With a total investment cost of solar power water pumps Subak Semaagung ????????1.168.137.010.
