Abstract

Solar Rooftop PV is one solution in reducing CO2 emissions and the increasing consumption of electrical energy. Based on PP No.79 of 2014, Indonesia is committed to utilizing 23% of the total renewable energy of the total by 2025. In the General National Energy Plan (RUEN), in 2025 Indonesia targets the capacity of electrical energy from new and renewable energy of 45 GW of which solar power of 6.5 GW (14%). In this research, we will discuss the design of Solar Rooftop PV in the Udayana University Library building. Based on the helioscope simulation results, at a real angle of 20.6o and 20.3o solar modules that can be installed as many as 84 units with a power capacity of 28.1 kWp while at an optimum angle of 14.66o, as many as 66 solar modules can be installed with power capacity of 22.1 kWp. Based on the results of the HOMER simulation, the configuration between the real angle PV mini-grid and the grid is able to produce energy of 83,253 kWh/year with an emission reduction of 41.764%, while the configuration of the Solar Rooftop PV with the optimum installation angle with the grid is able to produce energy of 79.775 kWh/year with a reduction in emissions of 34.527%. From the results of the HOMER simulation, an economic analysis was carried out with an energy selling price of Rp. 900/kWh. The two Solar Rooftop PV designs are worth investing in where the Solar Rooftop PV design with a real installation angle of 20.6o and 20.3o is able to return the initial investment costs in the 17th year while the Solar Rooftop PV design with an optimum installation angle of 14.66o able to return the investment cost in the 20th year.

Abstract

The availability of renewable energy in various sectors certainly needs to be improved, one of which is Solar Power Plant or PV. The province of Bali has a Solar Power Plant (PV) development target of 108 MW by 2025. The Solar Power Plant target has been stated in the RUEN (National Energy General Plan) policy. Efforts made by the Province of Bali to support and to realize the RUEN target are in the Bali Governor Regulation (Pergub) No. 45 of 2019 concerning "Clean Energy Bali". One of the areas in Bali that can be developed as a PV development is Nusa Dua area. In this area, the integration of conventional grid systems and renewable energy (PV Rooftop) can be carried out. In this journal, the author proposes several scenarios that are expected to be considered in planning the integration of a 20 kV grid system with renewable energy power plants. Some of these ideas are the integration of 25%, 50%, and 100% of PLTS capacity in meeting electrical energy needs. The purpose of the scenario is to find out the direction of the flow supplied by the PV, and to know whether the grid will remain stable or not if disturbance occurs.

Abstract

Indonesia have potential sunshine over year, it makes indoensia has a large source of renewable energy. However, renewable energy usage is very low. One of the renewable energy is solar power plants (PLTS). Medan City is one of the highly populated cities and it makes Medan city very limited land to build PLTS, and the solution is to build rooftop PLTS. Therefore, this research discusses the planning of PLTS on the roof of the Manna Helvetai Indonesian Methodist Church Building. The design of this PLTS is simulated using the Helioscope simulator. Solar modules are installed as many as 35 pieces and have 1 inverter with a capacity of 20 kW and produce potential energy of 15.8 kWp. Based on the results of the rooftop solar power plant design and the results of the calculation of electrical energy production, it can be analyzed that the economic development of rooftop solar power plants is considered feasible because it meets the criteria of Net Present Value (NPV) greater than zero, namely Rp 44,638,904 and Benefit-Cost Ratio (B-CR) greater than one, namely 1.19 and Discounted Payback Period (DPP) which is reached at the life of the solar power plant.

Abstract

The road is a public facility that is quite important for the community in connecting access between regions. Public street lighting (PJU) is part of the road's complementary infrastructure which can be installed on the right or left of the road section or in the middle (on the road divider). LED is a type of lamp that is often used in PJU throughout Indonesia. In this study, solar trees are designed as a source of environmentally friendly electrical energy which will be added ongrid to the public street lighting system (PJU). This study aims to analyze the selection of the type of lamp, the capacity used and the design to be used on the Ngurah Rai Bypass Road. The location chosen from the planned Solar Tree installation is the Ngurah Rai Bypass Road for street lighting. This is intended as an application for the utilization of renewable energy, and to find out what percentage of savings is generated. The results of the tests in this study produce calculations based on the kWh meter on the Ngurah Rai Bypass Road using a solar panel of the Mono Full Screen type DHM-54X10/FS 390~420W with a maximum power of 420 watts, resulting in: First, the solar tree uses four panels with a maximum power of 1680 watts. second, the design of solar tree poles that are adequate to the conditions on the Ngurah Rai Bypass Road, namely the "Tedung" and "Kayon" shapes which will contain four panels on each pole. Third, the savings obtained from using this Solar Tree are 18.69%.

Abstract

Renewable energy must be developed considering the depletion of fossil fuel reserves and the instability of fossil fuel prices. The development and implementation of environmentally friendly renewable energy sources needs serious attention. IESR's calculations in 2019 said that the potential for Micro hydro power plants (PLTMH) in Bali reached 15 MW. This research was conducted due to the presence of sufficient head and water flow as a potential to be PLTMH on the Yeh Dikis river. The purpose of this study is to identify the potential for electrical power that can be generated at the research location on the Yeh Dikis River, Banjar Lebah, Tabanan Regency, and determine the type of turbine to be used. The method used in this research is observation and literature study. The results of measurements and calculations performed, the available discharge potential is 0.381 m3/s and head fall is 8.2 m. The crossflow turbine is a viable option for implementing in the design of this PLTMH system on the Yeh Dikis river. The potential power that can be generated with a turbine efficiency of 0.75 and an assumption of a generator efficiency of 0.9 is 15.516 kW.
