Identification of Potato Supply Chain Network Design To Increase Farmer’s Income : Studi cases in Kejajar Village, Wonosobo, Central Java

The problem in this research is the supply chain network. This research was aimed to know 1) How was the picture of the current potato supply chain in Kejajar Village, Wonosobo, 2) How was the value chain for the potato commodity, 3) the benefits obtained at each link in the value added that have been given to the potato commodity and 4) the design of a potato supply chain that could provide value added so that it can be profitable for farmers. This research was carried out in Kejajar village, Wonosobo, Central Java. This type of research was descriptive quantitative where the method used in selecting respondents was the snow ball sampling method. The data processing method used descriptive analysis method SCM, Value Chain method, Value Added method, and simulation of chain design using SCM software. The results showed that there were four marketing channels in the potato supply chain in Kejajar, namely channel I farmer-collector-local wholesale market-retail, channel II farmer-collector-local wholesale market-wholesale market outside the province, channel III farmer-collectorwholesale market outside the province, channel IV farmer-local wholesale market-retail. The result of quantitative analysis showed that the highest income was obtained by farmers, but it needed to be underlined that they took the longest time to obtain this income due to the harvest process. Whereas the second largest income was obtained by collectors who got within three days. Value Added analysis using the Hayami method shows that collectors get the biggest profit from selling potatoes to p. local parent that is equal to 89%. The new supply chain design was implemented using powersim by cutting one of the supply chain actors, namely collectors and replacing it with agricultural cooperatives, where with this simulation it can be seen that farmers' income has increased 30%.
