Study of Environmental Impact Improvement for Shrimp Feed Production Companies

Abstract

The fishing sector in Indonesia plays an important role in driving the national economy. Shrimp exports have increased from 162,256 tons in 2015 to 239,227 tons in 2020. Shrimp farming relies on proper management of shrimp feed. Inadequate feed management can result in organic waste build-up, harming shrimp growth, survival, and production efficiency. This research identifies the potential environmental impacts of a shrimp feed production process unit based on the gate-to-gate approach, with shrimp feed as its main product. Environmental impact identification is conducted using the Life Cycle Assessment (LCA) method using Microsoft Excel as tools. The LCA stages consist of goal and scope definition, life cycle inventory (LCI), life cycle impact assessment (LCIA), and data interpretation. The method used is ReCiPe 2016 (H) midpoint impact assessment. Based on the results of the LCA study analysis, an environmental impact reduction scenario analysis is performed using an environmental program. The environmental impact assessment using LCA indicates that in the production process of 1 ton of shrimp feed, the most dominant environmental impacts are global warming potential (228,127 kgCO2eq), and freshwater eutrophication (0,000175 kgPeq). In the production process of shrimp feed, the largest contribution to the environmental impact comes from the Boiler unit and Wastewater Treatment Plant (WWTP). Then, Analysed efforts to deal with environmental impacts on the shrimp feed production process uses the Analytical Hierarchy Process (AHP) method.
