Abstract
This study uses a goal programming approach for the dual purpose of planning the production of rice-corn-soybean intercropping in the Border Area of Sanggau Regency. In this study, seven objectives were formulated, (1) maximizing the income of rice-corn-soybean intercropping in a year, (2) minimizing farming costs, (3) minimizing labor, (4) maximizing urea fertilizer, (5) maximizing NPK fertilizer, (6) maximizing manure and (7) minimizing land area. The study was conducted in September-December 2019. The study used a survey method. The data collection method used purposive sampling. Respondents were farmers who plant intercropping rice-corn-soybean. The numbers of respondent was 30 people, data collection by random sampling. The method of data analysis was using income analysis, R/C, and Multi-Goal Programming. The results showed that optimization can be achieved with a yearly income goal of IDR 85,566,600; farm costs IDR 31,249,250, the labor of 6,024 people, use of urea fertilizer as much as 400 kg, use of NPK fertilizer as much as 1,500 kg, use of manure as much as 3,000 kg, and land area 6,140 ha. Optimization is achieved when farmers cultivate intercropping rice-corn with an area of 1.99 ha and intercropping with soybean with an area of 0.95 ha.
Highlights
The threat of global food security is influenced by the increase in human population and the decrease in harvested area
The research is directed at farmers who grow rice, corn and soybeans based on information from the Field Agricultural Extension Officer, Sekayam District
The geographic position of Sekayam sub-district is located at North Latitude (LU): 0 "49'10.05 and East Longitude (BT): 110" 25'31.65. (Fig.1).The area of Sekayam subdistrict is around 841.01 km2 or 84,101 ha
Summary
The threat of global food security is influenced by the increase in human population and the decrease in harvested area. Modernization of traditional systems with production-oriented and production-oriented planting practices and economics as a food security strategy for future generations [1]. Food self-sufficiency in rice, corn, soybeans for the Indonesian state must be achieved in the few years. Commodities of rice, corn and soybeans as food and animal feed commodities. Corn commodity is needed by the animal feed industry. Soybean commodities are needed to meet the home industry of making tofu, tempeh, soy sauce, milk and so on. Fulfillment of food needs is still vulnerable, this condition occurs because it is still imported. The target of corn production is to increase to 23.16
