Comparative Study of The Life Cycle Assessment Model for Agricultural Solid Waste Management: Case Studies in East Ungaran and West Ungaran Districts, Semarang

Abstract

Abstract The increase in population affects the production of available food; this also increases agricultural activities and the waste produced. Improper agricultural waste management harms the environment, so a good agricultural waste management strategy is needed. The areas that are the object of study are East Ungaran and West Ungaran Districts, Semarang Regency. This area has great potential in the agricultural sector. This plan aims to analyze the existing conditions, volume, and mass balance of agricultural waste and their environmental impact using the life cycle assessment (LCA) and material flow analysis (MFA) methods to determine the appropriate strategy for managing agricultural solid waste. It is planned to manage agricultural solid waste using two alternative solutions, which are then compared using the LCA method using the SimaPro application and the Analytical Hierarchy Process (AHP) method involving two experts in the agricultural sector. Based on the analysis, processing agricultural solid waste as bokashi fertilizer and silage livestock feed is the most suitable method and is of interest to farmers.
