In the 2020 fiscal year, the Ministry of Energy and Mineral Resources of the Republic ofIndonesia provided PLTS On-Grid grants to the Province of Bali as many as 10 PLTS locationsin Denpasar City. One of them is in the Regional Development Planning Agency (BAPPEDA) ofBali Province with an installed capacity of 25 kWp which is connected to the PLN network.BAPPEDA Bali is an example of the NRE Development Program and the Regional Medium-Term Development (RPJMD) that supports the PV mini-grid sector. This research wasconducted to determine the performance of the PLTS electrical system and to simulate theresults of PLTS production using Helioscope software so that it can compare the simulationresults of 2 scenarios with real conditions to determine the level of effectiveness in savingelectricity bills and the factors that influence the results of PLTS energy production. The resultsshowed that the potential for electrical energy generated for a year from the simulation ofScenario 1 and Scenario 2 was 38.90MWh and 39.07MWh. It is known that the real energyproduction from July to December 2021 is 18,083 kWh with the simulation results of scenario 1and scenario 2 from July to December 2021 which are 19,810 kWh and 20,015 kWh. Thedifference between real energy production and the simulation results in scenario 1 and scenario2 is 1,727kWh with a percentage of 8.72%, and 1,931kWh with a percentage of 9.65%. Thepercentage of savings obtained for 6 months in 2021 compared to 6 months in 2020 is 56.42%with a saving value of Rp. 18,783,953.

Technological developments in the field of electronics to date have made the humanmindset advanced in the application of electronic equipment. One example of its development isremote control of electrical equipment. Many people use these developments as a means offacilitating life activities in solving problems that occur. The use of the internet in life can beused as an example in the use of technological developments. The internet is one of thecommunication media that has many benefits in increasing effectiveness, work efficiency, andmonitoring. The internet can be used as a transmission medium for control and monitoringsystems. With the internet, one can control electrical equipment and monitor the condition of thehouse. The concept originated from the Internet of Things or IoT. IoT is a concept where alltools and services in the system are connected to each other using internet media. Based onthese problems, a smart home system was created that functions as control of electricalequipment, smoke detection, monitoring of temperature and humidity in the room. Themonitoring and control system is integrated with Android applications and based on the Internetof Things.

Four Season Jimbaran Hotel is one of the hotels in Bali using a cooling system which isusually called the water chiller. The electrical energy consumption in Four Season Hotel is oneof the factors that increase the use of electrical energy in which the star delta system is stillused to switch on the pump. Along with the electricity rate which keeps increasing every year,the electrical energy consumption in Four Season Hotel can increase the operational cost. It isconcluded that one of the largest electrical energy consumptions is water chiller pump. Chillerpump is a pump used for pushing water flow towards chiller condenser and Air Handling Unit(AHU) when the water chiller system is still active. Starters of the chiller pump used in FourSeason Jimbaran Hotel are inverter and star delta. The method used in conducting research was calculation of the electrical energy requirement and cost in two pumps set by star delta atan initial frequency of 50Hz in water chiller pump 160 TR, compared with inverter system withthe decrease of frequency by 5Hz (45Hz) in water chiller pump 230 TR. Monitoring wasperformed by analyzing the consumption of electrical energy (kWh), temperature (°C), andhumidity (%) in every pump set by every system. In these two pumps, energy consumption(kWh) and cost were compared in daily, weekly, and monthly needs. From the result ofresearch, in inverter system, the frequency reduction by 5Hz in water chiller pump 230 TR cansave electrical energy of 117,120 kWh and the cost of IDR 130,471,680 in the next five years.The comparison analysis of operation of the chiller pump supplied with star delta (fixed speeddrive) with an inverter (variable speed drive) has a difference energy consumption of 117,120kWh in both systems and the difference cost is Rp. 130,471,680.00 in next 5 years.

The single phase to ground fault on the 150 kV transmission line GIS Pesanggaran –Nusa Dua Substation has a high fault impedance so that the distance relay as anauxiliary safety device cannot detect the disturbance. Directional Ground Relay (DGR)was chosen as an auxiliary protection relay to secure the system from single phase toground faults. Installation of auxiliary protection relays requires planning and relaysetting steps to obtain Iset, TMS and trip time. The calculations that have been carriedout get the results of DGR setting with a pickup current range of 0.0522 – 0.0722 A.DGR will work after 2.297 seconds if the differential relay as the main protection relaydoes not work or fails and the distance relay as a backup protection does not succeed insecuring a single phase fault to ground as well.

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.
