Supply chain green productivity improvement for sugar industry

Abstract

The sugar industry has a vital role in meeting domestic demands; therefore, it is crucial to increase productivity and supply chain efficiency. Productivity improvement should not only focus on economic efficiency but also the environmental impact called the principle of green productivity. This paper aimed to discuss the potential implementation of green productivity improvement activities and determine the level of green productivity that has been achieved in the supply chain of the sugar industry. The analysis began with supply chain configuration analysis, analysis of seven waste sources with Green Value Stream Mapping (GVSM), and inference of the green productivity level with Fuzzy rule-based. The results of the supply chain analysis show that two activities required to be analyzed for productivity, namely the sugarcane cultivation and the sugar milling processing division. The green productivity index in the current state of plantation supply chain activity was 0.90 and processing was 0.61. Green productivity improvement with good housekeeping and efficiency resulted in a GPI of 1.81 for plantation supply chain activities and 2.30 for processing. The fuzzy inference shows an increase in green productivity in the supply chain processing activities from a bad label to normal.
