Abstract

Currently, 80% of conventional energy is used to meet the needs of industry and the general public. Using new, renewable energy from the sun is an effort to mitigate climate change by reducing greenhouse gases (GHG). Al-Jihad Boarding School, an Islamic educational institution with around 1,200 students, is one of the biggest consumers of conventional energy. This study aims to plan photovoltaic solar cells, calculate the amount of power that can be generated, calculate the amount of GHG emission reduction from photovoltaic solar cells and the costs required for installation at Al-Jihad Islamic Boarding School. The planning results were analyzed by adjusting the selection of a 12 KVA inverter, 44 polycrystalline photovoltaic solar cells, and other complementary materials such as cables, MCBs and supports. The amount of power generated from photovoltaic solar cells at the Al-Jihad Islamic Boarding School in Surabaya is 12 kWh. Climate change mitigation efforts by reducing GHG emissions through solar cell photovoltaic planning at the Al-Jihad Islamic Boarding School in Surabaya can reduce CO2 greenhouse gases by 1,200.5 kg, NH4 30.013 kg, and N2O 0.019 kg. The cost required for the installation of photovoltaic solar cells is Rp. 209,850,400.

Abstract

Introduction: The presence of microplastics in the environment increases the diversity of types of pollutants in waters, including clean water sources on the surface and underground. Karst areas have unique hydrological characteristics, with cracks and fissures between the rocks that can be potential routes for the transport and accumulation of microplastics in underground river flows. In this study, we want to know the distribution and abundance of microplastics in underground rivers in the karst area of South Malang, Indonesia. Methods: Samples were collected purposively from underground river of Lowo, Banyu and Sengik. Microplastics were prepared using a diluted solvent of 30% H2SO4 and 30% H2O2. The sediment sample was dried and then filtered twice using 300-mesh size nylon filters until microplastic particles accumulated. Results and Discussion: Microplastics were detected in all water samples, with an average abundance ranging from 1.8 to 2.3 particles per liter. Fibers were the dominant microplastic type, followed by fragments and films, while the color distribution includes blue, white, red, yellow, black, green, pink, and brown. Conclusion: Microplastic contamination has been found in underground river flows in the karst area of South Malang, Indonesia. Karst soil, traditionally viewed as a natural filter, is not impervious to plastic pollution. This suggests significantly higher surface contamination than previously assumed. Therefore, reducing surface pollution is essential to safeguard the precious quality of underground aquifers and protect public health above.

Abstract

The increasing volume of waste generation in Bungurasih Village, Sidoarjo Regency, has created an urgent need for adequate waste management facilities. The existing Temporary Waste Storage (TPS) is suboptimal, equipped only with four simple transport carts and an incinerator lacking an emission control system. This study aims to evaluate the current condition of the TPS, analyze waste composition, density, and generation rate, and redesign the facility into a Reduce, Reuse, Recycle Waste Processing Site (TPS3R). The research employed a literature review and qualitative descriptive approach, supported by primary data collection through eight consecutive days of sampling. The results indicate that the average waste density reaches 428.84 kg/m³, with a daily waste generation of 6,359.70 kg. The redesign includes the construction of a TPS3R on an area of 809 m², consisting of sorting zones, organic waste processing, composting, storage, and supporting facilities. The estimated total cost for the TPS3R construction is IDR 1,769,480,000. This result is expected to serve as a planning reference for community-based integrated waste management systems in rural areas.
