Faktor-faktor yang Berpengaruh Terhadap Indeks Pertanaman di Beberapa Agroekosistem

Abstract

Increasing the planting index is a strategic policy and program to increase the efficiency of available land use because it is almost impossible to extend land by opening new fields. Seeing the various potentials and constraints that exist in increasing the crop index, it is necessary to examine the factors that influence the application of the crop index increase in various agroecosystems. The purpose of this study is to determine the factors that influence the increase in cropping index in 3 agroecosystems, namely dry land, rainfed lowland and swamps. This activity was carried out in 5 provinces including the provinces of Banten, West Java, DI Yogyakarta, East Nusa Tenggara and South Sumatra from August to December 2018. The site selection was done purposively based on agroecosystems. The collected data is then tabulated and analyzed using quantitative and qualitative approaches then interpreted descriptively and analyzed with multiple linear regression analysis. The fixed variable (Y) is the crop index and the independent variable (x) is labor, water availability, agroecosystem, pilot, availability of capital, water source, assistance, and extension media. From the multiple linear regression analysis, the results show that the factors that have a significant effect on the application of an increase in cropping index are agroecosystems, water availability, water sources, assistance and labor. Therefore, to improve the application of an increase in cropping index in dryland agroecosystems, rainfed lowland and wetland need to be concerned and optimalized.
