Diversification and Optimization of Integrated-Farming on Dry Land in Musi Village, Gerokgak District, Buleleng Regency

Abstrak

The objectives of the research were (1) to analyze the gross margin of integrated-farming (2) to analyze whether farming diversification in dry land integrated farming was optimal. The sample of the research used a census sampling technique. This sampling technique uses all members of SIMANTRI 001 as a sample with a group of 20 people. The actual income analysis used is farming analysis through gross margin calculation. Optimization analysis and maximum revenue are analyzed using the linear programming (LP) method which was completed with the assist of BPLX88 software (Eastern software product, inc. 1984). The results showed that based on the results of gross margin analysis, with an average dry land area of ??0.497 ha, the actual income for maize MT-1,  maize MT-2, peanuts and cattle was Rp. 696,326,650 per year. Based on the results of linear programming analysis seen from the primal problem solution, it shows that the first maize (PJG1), second maize(PJG2), peanuts (PKT) and cattle (PSAPI) are cultivated on a basic or profitable basis. This shows that the ??0.497 ha of land that has been used by the sample farmers contributed to obtaining the maximum income of Rp. 697,333,800 per year. Furthermore, in the dual problem solution, all land constraints per branch of farming with a land area of ??9.95 ha for each plant have been used up. This shows that the land constraints of MT-1 maize, MT-2 maize, and peanuts are binding used up without any residue (slack). However, some of the constraints are not binding, this can be seen in the stock of labor in January-December which has not been used up. Based on the optimization analysis through the linear programming method with the assist of BLPXX8, it was carried out optimally, this was proven by the maximum income of Rp.697,334,000 means that there is an increase in income of Rp. 1,007,350 (0.14%), from the actual income during the research of Rp. 696,326,650. To increase farm income, considering that there are still workers left in farming activities, farmers are advised not to hire labor in their farming.
