Evaluation of Biodiesel B30 Consumption Among Traditional Fishermen in Coastal Areas: a Case Study of Central Java’s North Coast

Abstract

This study evaluates the acceptance of traditional fishermen toward the use of B30 biodiesel as a marine fuel in the coastal area of Tegal, Central Java. B30 biodiesel, a blend of 30% biodiesel and 70% diesel, is promoted as a renewable energy-based alternative fuel that aims to reduce emissions and support sustainable development. The B30 biodiesel available in the study area is a subsidised fuel intended for specific types of fishing vessels, namely those with a capacity of less than 30 gross tonnage. A quantitative approach was employed through laboratory analysis of three fuel samples and a perception survey among fishermen regarding the technical and administrative aspects of fuel distribution using a Likert scale method. Field observations of the subsidised fuel refuelling process were also conducted to assess the biodiesel B30 distribution system. The laboratory results showed that the fuel generally met national standards, although some samples exhibited low cetane numbers. On the other hand, fishermen's perceptions indicated a low level of trust in the fuel's quality and efficiency, particularly regarding engine performance and maintenance requirements. Many fishermen also expressed concerns about complex administrative procedures and called for quality assurance from fuel suppliers. These findings underscore the importance of enhancing distribution systems, streamlining regulations, and highlighting the benefits of biodiesel to foster trust and promote the adoption of B30 biodiesel among fishing communities, thereby supporting a clean energy transition in coastal regions that benefits local communities.
