The communal salt farmer ventures grouping strategy in Sumenep District using the P-Median method to minimize transport distance in food supply chain network.

Abstract

Advance research has successfully shown that the farmers grouping in the supply chain network can reduce the total distance of commodity transport. The purpose of this study is to group the communal salt farmer ventures (KUGAR) in Sumenep District to minimize the total transport distance of salt commodities in the food supply chain network. Location coordinates and salt production capacity of each communal salt ventures are required to be able to calculate the total transport distance. Site survey was conducted for each communal salt ventures to mark locations on the Google map and record production capacity. Using the Google map API the distance data between communal salt ventures is collected and built distance matrix from one origin venture to another destination venture. The communal salt ventures grouping is done by the P-Median method. The experiment was conducted with an alternative of 2 groups, 3 groups, 4 groups. Total minimum transport distances as low as 127.82 km are achieved with 4 groupings. The first group was centered at Asapok Angin venture in the village of Pragaan Laok, the sub-district of Pragaan with 13 ventures member. The second group was centered at Mekar Jaya venture in Karanganyar village, Kalianget sub-district with 41 ventures member. The third group was centered at Usaha Bersama VII venture in the village of Gersik Putih, Gapura sub-district with 16 ventures member. The fourth group was centered at Persada Indah VII venture in the village of Kertasada, the Kalianget sub-district with 20 ventures member.
