Increasing value in robusta coffee processing through biogas utilization: An indonesia case study

Abstract

Robusta coffee is a leading commodity in Indonesia that accounts for 86% of total coffee exports in Indonesia. In addition, the issue of energy scarcity and the push for implementing a sustainable industrial system pose new challenges for Indonesia’s coffee industry to transform into a bio-industrial agricultural system. Starting from these issues, this study aims to assess the added value and impact on business profits from robusta coffee processing using biogas and LPG. The study was conducted in a bioindustrial farming system centre based on coffee and dairy cattle integration in Boyolali District, Central Java, Indonesia, from December 2023 to February 2024. The Hayami method was used in analyzing value-added. The analysis findings show that value-added and profit in the biogas-fueled industry have higher values than those in the LPG-fueled industry. Support is needed to develop biogas as an alternative energy and knowledge and training in processing waste as raw material for biogas. It is hoped that this research can improve the welfare of farmers and business actors, help implement sustainable agriculture, and become a model for other regions that want to create bioenergy using local resources.
