<![CDATA[The limited availability of natural resources and the impact on the environment that regularly using fossil-based electricity become the basis for the government to develop renewable energy. One of the potential uses of renewable energy in Indonesia is a rooftop solar power plant which in its design does not require a large area of land and space for the placement of solar modules. This research designing rooftop solar power plants with an on-grid system on the Udayana University Rusunawa building with the capacity scenario of 20 kWp, 15 kWp, and 10 kWp using HelioScope. Based on the results of rooftop solar power plants production can be seen the potential cost savings of electricity bills each year. Based on the results of the design for rooftop solar power plants scenario, the number of solar modules obtained is 40 pieces, 30 pieces and 20 pieces with potential savings in electricity bill costs of Rp. 33.391.515, Rp. 28.933.478 and Rp. 23.269.285 per year.]]>

<![CDATA[Lake Batur has the potential to build a floating solar power plant to improve voltage drop disturbances. The author uses three scenarios using power flow analysis and transient analysis for each scenario in Kintamani. Scenario 1 with a floating solar power plant capacity of 10 MW has a positive impact by increasing the busbar voltage value but there are reverse power conditions that can disrupt the power system at the Payangan Substation. Scenario 2 with a floating PLTS capacity of 1.2 MW has a positive impact by increasing the voltage value and does not cause reverse power at Payangan Substation. Scenario 3 with a floating PLTS capacity of 3 MW has a positive impact by being able to increase the voltage value and does not result in reverse power at Payangan GI. When the floating solar power plant loses power production, it causes a decrease in voltage value, then the system stabilizes again.]]>

<![CDATA[Water is a fundamental necessity for agricultural land and can be obtained from various sources depending on its geographical location. The Keliki Village Farmers Group in Subak Malikoda faces the challenge of drought, leading to a shortage of water supply during the dry season. In this research, the Solar Irrigation Pump (SIP) is designed with a solar tracker system to pump groundwater with the aim of enhancing irrigation water supply for Subak Malikoda during the dry season. The design of the solar-powered irrigation pump system consists of an 18.5 kW submersible pump coupled with a 23.1 kWp PV system using 60 monocrystalline solar modules equipped with a solar tracker and utilizing a 30 kW inverter. Based on the conducted analysis, the PVSyst results show that the SIP without a solar tracker can operate for 6,067 hours with an average water discharge of 274.9 m3/day, based on the received global effective irradiation of 1765.1 kWh/m2 in one year. However, with the use of the solar tracker system, the pump can operate for 6,933 hours with a water discharge of 305.2 m3/day and global effective irradiation of 1963.8 kWh/m2 in one year. The results of the analysis conclude that the SIP with a solar tracker system is capable of operating optimally and meeting the water discharge requirements of Subak Malikoda. This positions the solar tracker system as an effective solution in enhancing the water supply for Subak Malikoda during the dry season.]]>

<![CDATA[Potential of renewable energy is essential to support Bali Clean Energy, one of the energy that can be exploited is Solar energy. However, by 2023 the potential has been exploited only 1,48 percent. One of the reasons why Solar Plant construction in Bali is slow is because it is difficult to find land large enough to build Solar Plant on a large scale. However, solution to overcome land constraint is to utilize the water body through floating Solar Plant application. In the Project, the Floating Solar Plant Sidan Dam utilized body of the Water Dam and work pictures from the Planing of the Sidan Dam, with such data being used to determine the Floating solar Plant System in Sidan Dam. The design results showed that floating Solar Plant in Sidan Dam has a potential capacity of 1.45 MWp with a total of 2640 units solar panel and uses 12 units of inverters of 1.100 kW capacity. The energy production produced by the floating Solar Plant in a year was 2.564.007 kWh.]]>

<![CDATA[Using sustainable energy as a source of electrical energy is a safe way to increase ecosystem energy. One of them is the utilization of photovoltaic directed energy by upgrading the PLTS on top of the structure as a mechanism for introducing photovoltaic modules. The study finalized the plan to install PLTS on the roof of the I Gusti Ngurah Rai Airport parking lot as a source of electrical energy to reduce PLN electricity bills. The I Gusti Ngurah Rai Airport Parking Roof Solar Power Plant uses a battery-free on gridsystem with 600 units of 555Wp monocrystalline solar-based modules and four 100kW inverter units. The solar power plant to be built on the car park of Terminal I Gusti Ngurah Rai will have a capacity of 333kWp and will produce 604.929kWh of energy annually. The required speculation cost is Rp 3.004.620.000 and payback period for 6 years.]]>

<![CDATA[Electric vehicles use electrical energy as a substitute for fossil energy. Like gasoline vehicles that require gasoline filling facilities, electric vehicles also require electric energy charging facilities or commonly referred to as charging stations. One of the utilizations of solar power plant can be used for charging electrical energy at the charging station. In this study, a Power Supply Design was carried out for Charging Station for Two-Wheeled Electric Vehicles with Solar Power Plant System on grid in Widya Sabha Building Parking Lot, Udayana University. With the calculation of the energy needed in the Power Supply, the solar power plant design and manufacturing costs can be made. The design of this charging station can accommodate 10 electric motorbikes with solar power plant that can provide energy for 2 electric motorbikes per day for 9 hours of work alternately. By using 11.450 Wp solar panels arranged in series and 1 inverter with a capacity of 4.6 kW, this design produces 8.229 MWh per year. The total initial investment in this design based on market prices in Indonesia is IDR 99.213.000. Based on the investment feasibility, it shows that the investment in this design is feasible to implement.]]>

<![CDATA[The province of Bali has a solar energy potential of 1,254 MW but has only utilized 3.7 MWp up to the year 2020. One of the factors contributing to the slow development of PV in Bali is the need for large land areas for the construction of large-scale PV system. One solution to address the limited land availability for large-scale PV is by utilizing bodies of water through the implementation of floating PV. Lake Batur is the largest lake in Bali and has the potential to serve as a location for floating PV. This research aims to determine the technical potential of floating PV and design a system for floating PV in Lake Batur. With reference to the Lake Batur utilization plan and regulations for the use of floating PV, Lake Batur has a technical potential for floating PV of 76.44 MWp. The design of floating PV in Lake Batur is created with three scenarios. All three scenarios for floating PV show performance ratios within the range of 75-85%. The floating PV system also demonstrates an improvement in performance when compared to ground-mounted PV systems.]]>

<![CDATA[To accelerate the increase in the use of New Renewable Energy (EBT) in Bali Province in accordance with the General Regional Energy Plan (RUED), the Bali Provincial Government issued Bali Governor Circular Letter (SE) Number 5 of 2022. One of the applications of this letter is investment planning and analysis installation of a Solar Power Plant (PLTS) at the Abianseka II drilled well in Batuan Kaler Village, Gianyar. The Abianseka II drilled well is equipped with 4 pumps which on average consume 25,093.33 kWh of electricity per month. Based on the survey, the land available at the Abianseka II drilled well is sufficient for the installation of Ground Mounted PLTS covering an area of 478.5 m2. Therefore, it was decided to use 83 Jinko Solar JKM610N-78HL4-V 610 Wp modules with a total capacity of 50.6 kWp, as well as 1 LivoLtek 60 kW inverter and PLTS are capable of producing annual energy of 82,783 MWh, and have a performance ratio of 82.3%.]]>
