Optimization Model for Halal Gelatin Supply Chain with Carbon Emissions

Gelatin’s supply chain encompasses multiple actors before arriving at the end destination. However, costs related to distribution and carbon emissions along the supply chain could be high and motivates the exploration of efficient management solutions. This paper presents a mixed-integer linear programming model for a halal gelatin supply chain and multi-echelon problem. The echelons consist of multiple marine fisheries, multi-aquaculture, fish, and aquaculture processing plants, a halal gelatin plant, and customers. The purpose of this research is to maximize the total profit. The model considers carbon emissions resulting from production and transportation processes. A study case in East Java, Indonesia, is demonstrated to verify the proposed model. The results showed that the total profit and carbon emission produced were IDR S96,395,593,934 and 64,015.34 kg.CO2-eq, respectively.
