Abstract

Purpose:This study aims to analyze Indonesia’s energy transition by modeling the integration of solar PV and Battery Energy Storage Systems (BESS) while assessing the role of Indonesia–South Korea cooperation in enhancing technological adoption, investment, and energy diplomacy.Methodology:This research employs a multidisciplinary approach combining quantitative mathematical modeling of solar PV–BESS integration with qualitative analysis of Indonesia–South Korea cooperation through international political economy and energy diplomacy frameworks.Findings:The study finds that integrating solar PV with Battery Energy Storage Systems (BESS) could significantly enhance Indonesia’s grid reliability. Mathematical modeling shows that PV–BESS integration improves grid reliability and reduces coal reliance. reduce coal dependency, while Indonesia–South Korea cooperation provides technological, financial, and diplomatic leverage to accelerate the renewable energy transition.Implication:The findings imply that Indonesia should expand rooftop and utility-scale solar PV with BESS to secure the electricity supply, while hybrid systems can cut fuel costs in remote areas. Collaboration with South Korea can further accelerate deployment through technology transfer and local battery production.

Abstract

The growth of laundry businesses has led to an increase in the volume of wastewater containing detergents, organic matter, suspended solids, and phosphates, posing a potential environmental pollution risk if discharged without treatment. This study aimed to analyze the effects of varying the thickness of filtration media—composed of silica sand, bagasse, and activated carbon—and varying operational times on the reduction of pH, COD, TSS, and phosphate levels in laundry wastewater. A PVC-based gravity-flow (down-flow) filtration reactor was operated using three media composition variations: activated carbon-dominant (P1), bagasse-dominant (P2), and silica sand-dominant (P3), with operational times of 30, 60, and 90 minutes. The results indicated that variation P1 achieved the highest COD reduction efficiency (36.98%), while variation P3 yielded the greatest TSS reduction (98.18%). The pH levels of all effluents met the quality standards established by East Java Governor Regulation No. 52 of 2014. However, COD levels failed to meet the threshold across all treatments, and phosphate levels increased due to leaching from the bagasse media. Multiple linear regression analysis revealed that filtration media thickness significantly influenced effluent pH and TSS, whereas operational time did not have a significant partial effect on any of the parameters. As this filtration system could not simultaneously meet all quality standards, further treatment is required to enhance its effectiveness.
