Coffee is one of the main commodities of Indonesian plantation crops. During 2012-2016 South Sumatera Province is the largest coffee producer with a contribution 28.80%. Beside as coffee producer, South Sumatera Province has a coal mining potential as much as 38,5% from the national total supply (22.240,4 million ton). The development of coal industry causes coffee land conversion. The purpose of the study is to analyze the factors that determine the farmerâ€™s decision to sell their cropland to coal mining investor. The research was conducted in Lahat Regency, South Sumatera Province on February-March 2018. The sampling method used simple random sampling, with a total sample of 52 respondents. The research showed that land aggregates, total farmerâ€™s income, number of families and age of coffee plant significantly influence farmerâ€™s decision. Land conversion is a natural phenomenon that could not be prevented, but it could be controlled with restricting the license of coal mining, space arrangement (RTRW) and provide incentives to farmers as a form of support from the Government.

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.

The path finding optimization is the most widely discussed issues in the informatics scope. This was related to the increased needs of the transportation, distribution and industry. The method for solving search problems for the shortest path can be done using two methods, namely the conventional method and the heuristic method. The conventional method uses a mathematical approach that is easy to understand, but the search results require a relatively long time. In order for search time to be faster, a heuristic approach is needed, although it requires more parameters. A-star algorithm is a heuristic route search method that is very effective in finding the shortest route. In this study a web-based application was developed by integrating the A-star algorithm to find the location of rare plants in the conservation area. As for determining the distance between the coordinates of the plant using haversine formula. This application is very important because of the large number of plants and the limited guidance of researchers in finding the location of rare plants in conservation areas. The guide is presented in the form of an easy-to-understand graph accompanied by information about the plants sought.

Penggunaan lahan yang berbasiskan DAS menuntut pengelolaan sumber daya alam yang ada di dalam DAS tersebut harus optimal. Pengoptimalan penggunaan lahan ini bertujuan untuk memaksimalkan atau meningkatkan fungsi sosial ekonomi dan fungsi konservasi DAS atau menurunkan besaran erosi dengan memperhitungkan kendala keterbatasan sumber daya, sehingga menghasilkan DAS yang memiliki nilai ekonomis tingggi namun kelestarian ekosistem DAS tetap terjaga. Optimalisasi penggunaan lahan dengan metode Linear Programming-Simplex menggunakan Ms. Excel. Fungsi tujuan yang dirumuskan adalah untuk mendapatkan kombinasi optimal dari beberapa penggunaan lahan dengan nilai erosi yang sekecil mungkin. Sementara fungsi kendala dirumuskan berdasarkan pada hambatan-hambatan yang membatasi dalam alokasi penggunaan lahan yang didasarkan pada asumsi yaitu erosi yang diperbolehkan, luas masing-masing penggunaan lahan, arah pemanfaatan lahan, dan produksi tanaman pangan. Berdasarkan hasil dan analisis optimalisasi penggunaan lahan dengan kendala dan asumsi, maka diperoleh erosi total minimum sebesar 2.229.022 ton/tahun dengan alokasi penggunaan lahan yang optimal adalah 9.505 ha (hutan lahan kering primer), 9.505 ha (hutan lahan kering sekunder), 12.142 ha (hutan tanaman industri), 1.392 ha (perkebunan campuran), 16.062 ha (sawah), dan 1.269 ha (semak dan belukar).

Bambara groundnut (Vigna subterranea (L.) Verdc) is a potential commodity to be developed in Indonesia, however, the production is done only once a year, therefore, it needs proper seed storage. The aim of this research was to study seed deterioration patterns of four bambara groundnut landraces stored in packages with different permeability in an open storage system for up to 6 months. This experiment was conducted from November 2015 to July 2016 at Seed Technology Laboratory, Department of Agronomy and Horticulture, IPB. Stages of experiment as follow: calculation of packaging permeability, seed storage, preparation and fitting data to regression equation.The packaging used in the study is aluminum foil, pp plastic and plastic sacks which have measured its permeability. The result showed that the seed deterioration of four bambara groundnut landraces in three packaging permeability has common sigmoidpattern with equation model: y = a / {1 + exp ((x + b) / c)}. The seed deterioration pattern based on SG and EC variables with the faster rate of decline occurred in Sumedang landrace packed in plastic sack (permeability = 1.4681 g/day m2 mm/Hg), thus having a shorter storability. The slower rate of decline occurred in Gresik landrace packed in aluminum foil (permeability = 0.098 g/day m2 mm/Hg), this means that it has a longer storability.

Nutrient management strategies effectively and efficientlyis an additional effort to improvethe results obtaained by farmers and related to environmental sustainability. The use of N fertilizer, which is an essential nutrient for rice plants, needs to know the optimum dosage according to plant needs and soil fertility. The research objective is to determine the optimum N dose to get the maximum rice yield in irrigated paddy fields. The study was conducted in Matoangin, Bantimurung District, Maros, South Sulawesi, for two planting seasons, from January to August 2014. The first planting season lasted from January to April 2014 (rainy season), and the second planting season from May to August 2014 ( dry season). The experiment were used in a randomized block design with three replications. The dosage of N fertilizer consists of six levels, namely (N0) without fertilizer; (N1) 33.75 kg N / ha equivalent to 75 kg Urea / ha; (N2) 67.50 kg N / ha equivalent to 150 kg Urea / ha; (N3) 101, 25 kg N / ha equivalent to 225 kg Urea / ha; (N4) 135 kg N / ha equivalent to 300 kg Urea / ha, and farmer dose (N5) 168.75 kg N / ha equivalent to 375 kg Urea / ha. The results showed plant height, panicle length, number of filled grain and yields of Inpari-4 rice at the study site were influenced by N fertilization. Research in the rainy and dry season showed fertilization N increased growth and yield of rice by following a quadratic pattern, and dosage the optimum N fertilizer is different in each season. The optimum N fertilizer requirements to obtain the maximum results in the rainy season (6.78 t / ha) is 129 kg N / ha equivalent of 282 kg of urea / ha, while in the dry season takes 131.57 kg N / ha equivalent of 286 kg urea / ha to get maximum yield (7.15 t / ha). The dosage of fertilizer is more efficient compared to that applied by farmers, namely> 300 kg urea / ha (equivalent to 135 kg N / ha).
