Komponen Usahatani Pendukung Penerapan Peningkatan Indeks Pertanaman pada Beberapa Agroekosistem

Abstract

Increasing the cropping index is a strategic policy and program to increase the efficiency of available land use. Referring to the potential and constraints of cropping index improvement, it is necessary to review the supporting components that affect cropping index implementation improvement in some agroecosystems. The purpose of this study was to aims to analyze the components of farming that support the implementation of increased cropping index in upland, rainfed lowland, and swampy land. This activity was carried out in five provinces namely 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 were tabulated and analyzed using quantitative and qualitative approaches then interpreted descriptively and analyzed with multiple linear regression analysis. The dependent variable (Y) is the cropping index and the independent variables (x i ) are labor, water availability, demons tration plot capital availability, water resources, supervisory, and extension media. The results of the combined linear regression analysis showed that water availability and supervisory were the supporting components that have a significant effect on every agroecosystem. Meanwhile, water, capital and labour availability were variables that have a significant effect on the implementation of increased cropping index in upland agroecosystems. The dissemination media has a significant effect only on rainfed lowland, while the capital availability and water sources were supporting components that have a significant effect at swampy land.

Pola Tanam Padi untuk Produktivitas Tinggi dan Indeks Pertanaman yang Optimal di Lahan Rawa Pasang Surut

“…Dukungan inovasi dan teknologi untuk peningkatkan produktivitas padi di lahan rawa dapat dilakukan melalui peningkatan indeks pertanaman (IP) (Adri et al, 2013;Purnamayani et al, 2021). Umumnya petani di lahan rawa hanya sekali tanam dalam setahun (IP 100) dan hanya sekitar 10% areal yang sudah menerapkan tanam dua kali dalam setahun (Haryono, 2013).…”
