Abstract

Satrio Utomo SME is a batik small and medium enterprise located in Kedunggudel, Sukoharjo, which was established in 2010. This business specializes in producing two types of batik, written batik and stamped batik. Both production processes utilize Remazol as the raw material for synthetic dyes. Notably, while written batik exclusively employs 100% Remazol dye, stamped batik incorporates recycled Remazol dye. This study aims to calculate, analyze, and offer recommendations for enhancing eco-efficiency in the utilization of Remazole dye by employing the Life Cycle Assessment method with SimaPro 9.3 software to evaluate the environmental impact of both batik production methods. The results indicate that the eco- efficiency index for written batik stands at 1.03, whereas stamped batik boasts an index of 1.07, signifying superior eco-efficiency. This underscores the greater environmental impact of written batik, while stamped batik demonstrates a more favorable balance between economic and ecological considerations. The study proposes an enhancement strategy: increasing the production of stamped batik employing recycled Remazol dye due to its higher net value. For written batik, the recommendation involves transitioning from synthetic dyes to natural dyes, known for their environmental friendliness and ability to yield classic batik results.
