The application of the 'Jarwo Super' component to increase the cropping index of rice fields in the special capital region of Jakarta-Indonesia

Abstract

Jakarta, the nation's capital of Indonesia, has 414 hectares of rice fields. The fields generally owned by developers that are not been used/idle land. In general, the existing cropping index of the land is only 1-2 which has potential to be improved. The main of this research was to obtain a model of agricultural technology innovation package to increase rice productivity and field cropping index in Jakarta throught the application component of' Jajar Legowo (Jarwo) Super' technology. The observation data consisted of primary and secondary data on the characteristics of cropping patterns for a year. The data were processed using descriptive and economic analysis was tested based on the Revenue Cost Ratio (R/C). The results of research showed that the application package or component of Jarwo Super technology showed an increase in the planting index by 0.3-0.8 and also an increase in productivity ranging from 5 t/ha to more than 7 t/ha. Based on the R/C analysis, the application of component of Jarwo Super's technology package increases the cropping index from 1.83 to 2.32. It means that the introduced cultivation technology can improve farm efficiency every planting season and increase farmer income every year.
