Abstract

Growth in electric energy demand, domination of use of fossil fuels, and waste problems are fundamental to this research. The purpose of this research is to find out the electrical energy potential of the Putri Cempo Landfill waste, Surakarta. The potential of electrical energy is designed for waste power plant (WPP). Penetration of WPP as a Distributed Generation (DG) to the 20 kV electrical distribution network is analyzed to determine its effect on the growth of demand for electricity, power flow, and the index of the (SAIFI and SAIDI). This research applies the technology Sanitary Landfill to produce landfill gas (LFG) as the primary energy of WPP. In calculating the growth predictions of electricity usage in the industrial, household, public, and commercial sectors from 2017 to 2025 in APJ Surakarta, the DKL Method 3.01 is applied. ETAP 12.6 was applied to analyze the power flow in the form of power losses and voltage losses and the Section method to calculate the reliability index (SAIFI, SAIDI) before and after penetration of WPP in PLR 01 and GDO 04 of Manahan Substation, Surakarta. The results showed that Trash from 5 Regencies and Cities, WPP was able to generate a maximum power of 10.1 MW. During peak load, WPP is able to reduce electricity demand of Substation for 0.920% in 2019, 0.879% in 2020, 0.838% in 2021, 0.799% in 2022, 0.760% in 2023, 0.723% in 2024, and 0.686% in 2025. The drop voltage at the tip of the feeder (No Substation Transformer BSP01005) has improved 29.4%, power losses have improved 25%, SAIFI has improved 61.36%, and SAIDI has improved 29%, after WPP penetration.

Abstract

The lamp is the main construction facility in the company that serves as a support for the activities of the economic system and mobility in the company. An analysis of the difference between the use of LED lights with HPS lamps at PT. Bukit Asam Tbk. reference is used to recommend the use of appropriate (technical) lighting equipment for industrial areas and to obtain better cumulative costs and energy savings for the company in the future. In this study using the lamp replacement method with the same lumen level comparison. The goal is that later the level of lighting produced is the same for each lamp. From the results of this study it was found that the technical use of 70W, 150W, 250W and 400W HPS lamps has an efficacy level of 84 to 123 lm / W. Whereas the 80W, 200W, 300W, 450W LED lamps are 90 lm / W and the results of the cumulative value or the total cost of operating and maintenance costs for 15 years between HPS lamps versus the LED lights that occur is that in HPS lamps the total cost incurred amounting to 20,604,230,235 rupiahs while for LED lamps it is 27,787,386,324 rupiahs which can be seen that the use of more economical lighting is HPS lamps.
