LINEAR PROGRAMMING MODEL IN EFFORTS TO ALLOCATE LOCAL RESOURCES TO ACHIEVE OPTIMAL INTEGRATED FARMING RESULTS

Abstract

Climate change in the area of \u200b\u200bEast Selemadeg Subdistrict has been felt since the last ten years, causing cropping patterns and the management cycle of farming to become unstable. The availability of water on agricultural land is a crisis, even a few years before farmers could not harvest because they could not grow crops. The code makes this agricultural area rainfed. The shift in the planting season and harvest time is felt by farmers in Megati Village, Selemadeg District, Tabanan Regency, this is caused by the availability of water that is very low in the dry season. even almost none, in the rainy season the availability of water is abundant but quickly lost due to the condition of agricultural land that is unable to hold water for a long time. The aim of the study was to determine the cropping patterns and types of plants that are appropriate for cultivation in rainfed rice fields. The method used is the optimization of linear programming on cropping patterns of rice, corn and girlfriend water flowers to produce a cropping pattern model with maximum profit. Analysis of water availability, the best planting schedule for the Suka Mandiri Village Farmers Group in Selemadeg Timur District, Tabanan Regency, is November for Planting Pattern I (PT I) and February for Planting Pattern II (PT II) with cropping patterns: Rice; Rice-Rice; Corn-impatien basamina; paddy- impatiens balsamina. Based on the optimization analysis, from the recommended cropping pattern, which gives the maximum benefit is rice with impatiens balsamina.
