Abstract

The PLTS installed at the Mechanical Engineering Laboratory, Faculty of Engineering, UKI Jakarta is an On-Grid PLTS that plays a significant role in the development of technology and research in the fields of mechanical engineering and energy. The 2 HP waste shredder, used to recycle waste into reusable materials, is part of the efforts towards sustainability and efficient waste management. To support the operation of the waste shredder and reduce electricity costs, the laboratory has installed an On-Grid PLTS with a capacity of 3540 Wp. Based on power measurement data under no-load and load conditions with the 2 HP waste shredder, there was an energy export of 8 kWh and an energy import of 1 kWh over 11 hours. The power factor under no-load conditions was good, ranging from 0.96 to 1, which meets the standards set by PLN. However, the power factor when using the 2 HP waste shredder load ranged from 0.1 to 0.72, which does not meet PLN standards. The low power factor is due to the inductive load effect of the single-phase induction motor, such as that of the 2 HP waste shredder.

Abstract

The photovoltaic (PV) system installed at Trans Studio Mall Cibubur operates as an on-grid system designed to lower electricity expenses. It boasts a total capacity of 1507 kWp and has the potential to produce approximately 1,502,240 kWh annually. Between January and March 2024, the system achieved an energy saving of 406,560 kWh, out of an annual usage of 5,626,400 kWp recorded from September to November 2023. This led to a reduction in electricity costs amounting to IDR 421,106,125 for the same timeframe. The economic assessment indicates an initial investment of IDR 12,272,187,620 for the PV system, with yearly operating and maintenance (O&M) costs of IDR 92,581,876. Financial calculations reveal a positive Net Present Value (NPV) of IDR 5,125,472,158 and a Discounted Payback Period (DPP) of approximately 13 years and 7 months. The Break-Even Point (BEP) is anticipated in the 8.6th year, confirming that the project is a sound investment. Post-breakeven, the revenue generated from the PV system will convert into net profit, affirming the system’s economic viability. Keywords : PLTS, On-Grid, engineering economics

Abstract

Electricity is a vital necessity in modern life, but the increasing demand for energy presents significant challenges, especially due to the depletion of natural resources like petroleum in Indonesia. Renewable Energy (RE), particularly solar energy, offers a sustainable solution. Solar Power Plants (PLTS) harness solar energy, an unlimited resource, which has great potential in Indonesia. However, the adoption of PLTS is still hindered by high initial investment costs. This study compares the cost-effectiveness and operational efficiency between Off-grid PLTS, Generators, and PLN electricity at PT. Kipra Sarana Duta Agung. The results show that while the initial investment for PLTS is higher, its operational costs are very low because it requires no fuel or routine maintenance, making it the most economical and environmentally friendly option in the long term. Off-grid PLTS also offers energy independence by storing backup energy in batteries. In contrast, Generators require diesel fuel costs and regular maintenance, while PLN electricity requires ongoing monthly payments. The study concludes that Off-grid PLTS is a more efficient and sustainable energy solution with a payback period of six years. Additionally, Off-grid PLTS aligns with government policies promoting RE as a long-term solution to the depletion of fossil fuels and rising energy costs.

Abstract

ABSTRACT Fossil energy, which is the main source of electricity generation in many countries, makes a major contribution to air pollution and greenhouse gas emissions. Volioh photo solar energy panels (PV) offer an environmentally friendly solution, by utilizing abundant and unlimited solar energy. On-grid PV systems connect solar power plants to the power grid, enabling distributed energy production and efficient utilization of renewable resources. This research The use of on-grid PV-based solar energy is expected to be an important step in creating a more sustainable, efficient and environmentally friendly energy system. The results of the research show that when measuring PV without load, the PV voltage increases as the light intensity received by the PV increases, but the PV voltage experiences saturation starting from the light intensity of 164 lux. In the PV test under load the voltage is almost constant around (226.2 to 237.6) votl with changes in load current around (4.94 to 6.76) A Keywords: Solar Power Plant (PLTS). On-grid, Renewable Energy, Photovoltaic (PV) Solar Panels.
