Abstract

Natural rubber is one of the agricultural products in exceptionally high demand for industrial materials. In Indonesia, rubber is a major plantation crop grown all across the country. This research seeks to use the LCA technique, but its primary objective is to examine the consequences of the crumb rubber industry. Using sulfuric acid causes the emission of roughly 11,94705 kg equivalent of the gas sulfur dioxide into the environment. In contrast, using isoprene as a base material causes the emission of approximately 1090 kg equivalent to the gas carbon dioxide. Coal-derived energy accounts for up to 719,748 MJ, or 199,930 kWh, and is the critical focus in the quest for alternative energies. Because the macerator, creeper, hammer mill, and drying machine take 199.93-kWh of electricity to operate.

Abstract

This study investigated the implementation of solar panels in the Dumai Islamic Centre (DIC) Mosque, located in Dumai City, Riau Province, to reduce carbon emissions. The study presents an overview of the significance of solar energy utilization and its potential benefits in the context of mosque buildings. This research was aimed to assess the criteria for selecting the appropriate solar panel type, determine the power output and PV area required for the DIC Mosque, and estimate the carbon emissions reduction resulting from installing solar panels. The study employed a quantitative research design and utilizes the Analytic Hierarchy Process (AHP) to select the most suitable solar panel type. The results reveal that polycrystalline solar panels are the optimal choice based on efficiency, power peak, operation and maintenance, and price criteria. Installing solar panels on the DIC Mosque's roof, positioned at an optimal height, ensures maximum sunlight exposure and energy generation efficiency. Calculations demonstrate a significant reduction in carbon emissions post-installation. The carbon emissions reduction potential is estimated at 57.693 kg CO2 eq per day or 21,057.95 tons CO2 eq per year. This highlights the positive environmental impact of solar energy implementation in the DIC Mosque.
