Solar light is an environmentally friendly renewable energy. According to RUEN, BaliProvince has a fairly large potential for solar light utilization, namely 1,254 MW with a target forPLTS development in 2025 of 8.62% or 108.2 MW of its total potential. Therefore, this researchfocuses on the utilization of PLTS Rooftop on-grid as an energy supply at Kori NuansaJimbaran's residence which explains the specifications of the installed PLTS materials andcomponents, as well as the design of the PLTSinstallation in Rooftop terms of technical termsaccording to the requirements of PT. PLN (Persero). The method used is literature review,observation, data collection, data analysis and conclusions. The results showed that the totaldaily load calculation was 26,151 W/day and the total daily energy that could be generated fromthe calculation was 14.58 kWh/day with the measurement results at the research location of13.4 kWh/day where there was a difference of 1.18 kWh caused by due to losses in the system.When viewed from the total daily load the PLTS system has not met the needs, but functionallythe PLTS system is intended for daytime loads so that the needs are appropriate. Optimalinclination angle of 14.66calculation results areº however on measurementsusing a protractortool obtained18º this because the angle of inclination of the solar panels follows the direction ofthe slope of the roof. The installed PLTS design has met the standards of the Minister of Energyand Mineral Resources No. 49 of 2018 and has received an Operational Worthiness Certificate(SLO) from PT. PLN (Persero).

Increasing energy demand with limited resources is an obstacle in supplying demand for electrical energy sources at this time. The solution to this problem becomes essential due to the planning of excessive energy supply, as well as planning that does not meet the energy demand will cause new problems on the side of energy production. Therefore accurate energy consumption forecasting is very important. In this study, the projected use of energy in the processing industry sector in Bali uses LEAP software using a database from 2015 to 2018. The use of fuels in the processing industry in Bali according to modeling results will continue to increase until 2050. This increase due to an increase in population resulting in increased demand for processing industry products so that the production of processing industries has increased which directly increases fuel consumption. This increase in production is also due to increased purchasing power, this is shown from the increase in per capita GRDP of Bali province which has increased until 2050. GRDP of the processing industry according to modeling results has increased until 2050 this is in accordance with the energy needs of the processing industry , where an increase in the production of the processing industry will also result in an increase in the GRDP of the processing industry

This article discusses the design and simulation of the performance of a 1 kWp rooftopsolar power plant using a Helisocope. The input data required by the Helioscope is PLTS technicalspecifications such as solar panel technology, inverter type, number and type of modules selectedand land area. The location data required by the PLTS system includes the coordinates, the type ofroof of the building, the environment around the PLTS and meteorological data. The 1 kWp PLTS roofsystem designed at the location that the author uses uses 7 pcs Canadian Solar 195 Wp panels, 1pcs 1 kW AEC inverter, installed on the roof of the building facing north, and connected to the PLNnetwork via a net meter. This 1 kWp rooftop PLTS is capable of producing an average daily averageof 5,48 kWh, 41,07 kWh weekly, 164,29 kWh monthly, and annual 1971,5 kWh. Energy productionvaries by an average of 8% per month with the minimum production in January of 135,1 kWh and thehighest in July of 184,5 kWh. The designed 1 kWp PLTS roof produces a performance ratio of 73,6%with the irradiation received in a year reaching 1859,2 kWh/m2. The initial investment required to builda 1 kwp PLTS roof is IDR. 20.000.000.

Solar Power Plant (PLTS) is a renewable energy that converts sunlight into electricity.However, the construction of PLTS requires a large area of land so that for urban areas it is noteasy to get the required land. One of solution to this problem is to use the roof of the parkingbuilding as a rooftop solar power plant, the energy produced by the rooftop solar power plantcan be exported to the network because generally the energy demand for parking buildings isnot much. This paper discusses PLTS on the roof of parking buildings that have been built allover the world. The results of a review were obtained as many as 40 PLTS on the roof of theparking building which were built from 2010 to 2022 with a total capacity of 207,49 MW. ThisPLTS parking facility was built in the form of PLTS on the roof of the parking building, carportand parking canopy. Institutions that have built PLTS above their parking facilities includeairports, banks, malls, governments, water companies, recycling companies, pharmaceuticalcompanies, financial companies, car companies, hospitals, schools, stadiums and universities.

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.
