Abstract

Kejajar District is the center of potato farming in Wonosobo Regency, where the area has a larger harvest area and higher potato production yield than other sub-districts. This study aims to determine the level of coordination and collaboration between marketing institutions so that potato products can be distributed optimally. If one chain is disturbed, it will affect the other chains. This research was conducted by purposive sampling, and the research location is the most productive potato area in Wonosobo. The study started in May and ended in June 2022. The number of respondents in the study was 52 people, consisting of 4 wholesalers, 3 middlemen/shippers, 15 retailers, and 30 farmers. The results showed that the four wholesalers had overall control over the sales of potatoes in the Kejajar District. This condition illustrates that the potato market at the farmer level tends to have a strongly oligopsony market structure. Wholesalers have considerable capital power, so they can control middlemen. The marketing margin shows that marketing channel one provides a high price share to farmers of 46.15%, and the farmer share analysis received by farmers as potato producers in Kejajar District can be said to be efficient because the selling price received by farmers is more than 40% of the price at the consumer level.

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.
