Abstract

While having relatively high fishery production, the southern region of Central Java continues to produce poor and uneven interregional trade flows, reflecting persistent inefficiencies in market integration and spatial connectivity. This quantitative study examines the determinants of interregional trade flows of leading fishery commodities using an extended Gravity Model. Secondary data were obtained from Statistics Indonesia, the Ministry of Marine Affairs and Fisheries, and the Regional Development Planning Agency of Central Java, covering the period of 2018–2024. To explain trade volume between origin and destination regions, the model includes economic mass (Gross Regional Domestic Product), geographical distance, infrastructure quality, interregional price differentials, and market centrality. The findings demonstrate that statistically, the economic size of both the origin and destination regions has a positive and significant effect on trade flows. Distance and price differences, on the other hand, are statistically insignificant, suggesting that spatial separation and short-term price arbitrage are becoming less important. Infrastructure quality shows a positive but insignificant effect, indicating a supportive yet limited role. Meanwhile, market centrality exerts a profound and substantial impact on trade patterns. Theoretically, this study extends the Gravity Model by demonstrating that institutional market concentration outweighs traditional spatial frictions in regional fishery trade.

Abstract

Background. BUMDes Banjarwaru Sejahtera is a business owned and managed by the people of Banjarwaru Village, Cilacap Regency. Some of the businesses that have been managed by BUMDes Banjarwaru Sejahtera include renting molen machines and making handicrafts such as broom handles and woven bamboo household crafts which produce an abundance of wood waste left over from the production process. So far, this wood waste has been sold to tofu craftsmen as fuel for the tofu production process. Purpose. People can use wood waste as added value by processing wood waste into handicrafts that have high economic value so that they can improve the welfare of the people of Banjarwaru village. Through this community service activity, training will be held on the use of wood waste chopping machines so that processed wood waste can be made into handicrafts such as particle boards or other handicrafts. Method. The method used is a lecture method where the community service team who are lecturers at the Cilacap State Polytechnic provide training on the use of wood waste chopping machines to members of BUMDes Banjarwaru Sejahtera and several wood craftsmen in Banjarwaru village. Results. The results of this community service activity have had a positive impact on business development at BUMDes Banjarwaru Sejahtera. Conclusion. Through this community service activity, it can be concluded that this activity has had a positive impact on the business development of BUMDes Banjarwaru Sejahtera. Apart from this, training in the use of wood waste chopping machines can also increase the competence of wood craftsmen in Banjarwaru village so they can produce more varied crafts made from wood waste.
