Abstract

The study aims to determine the effect of applying for intercropping food crops (rice, corn, and soybeans = jagole) on the cropping index and income of urban farming community activists. This study was conducted by comparing the use of six models of growing food crops, namely three kinds of monoculture model of jagole, upland rice-soybean, sweet corn-soybean, and sweet corn-upland rice polyculture/ “Turiman”. Observational data includes data on land characteristics, annual cropping patterns in related locations, and input-output data of the test models. Corn and soybeans are harvested young. Data were processed using descriptive analysis and the economic feasibility analysis of the tested technology was based on the R/C ratio. Based on data, it is known that there is potential to increase the cropping index of dry or limited land in the Jakarta area, from 1-2 to 2-3 a year by optimizing planting through intercropping systems/ food crop Turiman. such as corn-upland rice-soybean. The results of the analysis showed that the soybean monoculture technology model, with yields of young soybeans, gave a higher profit (R/C 2.58), compared to the other models, namely sweet corn monoculture, upland rice monoculture, upland rice-sweet corn polyculture, soybean-sweet corn polyculture, soybean-upland rice polyculture, and (R/C respectively: 0.24, 0.54, 0.17, 1.25, and 1.71).
