Abstract

Cocoa has been developed in various regions in Indonesia. In developing cocoa farming, farmers still face the problem of low productivity, efficiency and quality of seeds. This is partly due to not using the right fertilizer. This study aims to analyze the effect of NPK Lodrin fertilizer use on the efficiency and income of cocoa farming in Gorontalo. The study was conducted in several Gorontalo cocoa production centers, namely in Gorontalo District and Pohuwato District in 2016. Data collection was conducted by survey method with questionnaires or structured questionnaires for 59 cocoa farmers. Respondents were farmers who used Lodrin NPK fertilizer and farmers who did not use Lodrin NPK fertilizer. The selection of respondents was carried out by stratified random sampling technique. The farming efficiency analysis method uses the Cobb-Douglas stochastic frontier production function model. Financial farming analysis was carried out to determine the level of cocoa farming income with the use of Lodrin NPK fertilizer. The results showed that the use of Lodrin NPK fertilizer significantly affected the increase in production, efficiency and income of cocoa farming in Gorontalo. The average level of farm efficiency both technical, allocative and economic efficiency of cocoa farmers using Lodrin NPK fertilizer is higher when compared to farmers who do not use Lodrin NPK fertilizer. The factors that influence the inefficiency of cocoa farming are farmer education and institutional factors, namely the frequency of counseling, participation in farmer groups, access to credit and technology assistance. The use of Lodrin NPK fertilizer increases the income of cocoa farming, as evidenced by the value of the R / C ratio and the value of return for higher production factors of farmers who use Lodrin NPK fertilizer.

Abstract

Watershed (DAS) is a complex ecosystem, where land quality is largely determined by land use activities. This illustrates the importance of analytical procedure, especially where the context in which the spatial pattern of land use in the future can be designed based on the risk of degradation in large areas. Data and information are necessary to be used as reference in designing a planning scheme related to land use. Geographic Information Systems (GIS) is a system that has the ability to analyze problems and their spatial and non-spatial combinations (queries) in order to provide solutions to spatial problems. Sustainable farming is an integral part of sustainable development, a farming system which preserves water resources, land resources, and plant resources in acceptable and suitable ways economically, socially, and environmentally. The research aimed to identify and classify critical land by spatial analysis. Based on identification of land, there were 12 individual units in the study area. Based on the spatial analysis, critical land classification was divided into not critical area of 1,818 ha (28.7.%), Potentially Critical 2,596 ha (41.06%), Moderately critical 1,631 ha (25.08%), Critical 226 ha (3.57 %). Most of the land in sub-basin Langge was a hilly area of 1180.6 ha (63.8%) with a slope of 12-25%; 25-40% and above 40%. Alternative farm management in this area was a conservation farm by mechanical conservation techniques (terraces) or vegetative with cultivation techniques hallway, living fences, grass strips and agroforestry.
