How to Mitigate The Production Risks on Coastal Red Chilli Farming in Kulon Progo Regency
Get PDFThe southern part of the Special Province of Yogyakarta consists of a coastline spanning over 113 km, under the administrations of Bantul, Gunung Kidul and Kulon Progo regencies, that can become an asset and resource of an important economy. Cabe Merah (red chilli) is one of the commodities that show high numbers of productivity in Kulon Progo Regency. Activities of red chilli farming on the coastal land of this regency have been growing, especially since the establishment of commodity auction market to help farmers sell their harvests. The study was conducted to (1) find out the size of production in red chilli agribusiness on coastal land, (2) to analyze the risk levels of production faced by the farmers, and (3) how to mitigate the production risks on coastal red chilli farming. There were 40 participating farmers from Banaran Village, Galur Sub-district, Kulon Progo Regency. The location was intentionally chosen by using multistage area sampling method. The data used were collected from the production and income of three growing seasons. Data analyses were performed using production risk and The House of Risk methods. Based on the variance coefficient, the production risks level was at 0,03 with the production lower limit of 9.596 Kg/Ha, which showed a low level of risk. The various risk mitigation strategies have been performed by the farmers to lessen the risks that can causes losses in the process of coastal red chilli productions

Contribution of Agricultural Sector Towards Regional Income Inequality of Sumatera Economic Corridor
Get PDFFinding of previous studies shows that Sumatera Economic Corridor is categorized as the highest income inequality. The Indonesian goverment enacts MP3EI (Master Plan for the Acceleration and Expansion of Indonesia Economic Development) program to promote equitable development where each economic corridor owns strategic economic sector. The objective of this study is to analyze the contribution of agricultural sector on income inequality in Sumatera Economic Corridor (SEC) using a weighted coefficient of variation. We use secondary time series data of Gross Regional Domestic Product (GRDP), number of population, and per capita income of a time range between 2002 and 2013. Data analysis shows that agricultural sector has the least contribution on income inequality. Consequently, goverment policy should be focusing on the development of agricultural sector in Sumatera Economic Corrido

Get PDFThis research aims to study the result of proper glyphosate and paraquat application and tillage system as weed controller and to get the proper herbicide application timing and soil tillage system for increased growth and yield of tobacco. The research was conducted in Pakel Village, Sumberpucung District, Malang Regency in July-October 2014. Method used in the research was Split-Plot design with 2 levels of tillage system as main plot and 6 levels of application herbicide timing as sub-plot with 3 replications. Glyphosate application before planting increased growth factor of tobacco i.e. number of leaves, plant height, and leaf area. Glyphosate application before tillage and planting increased yield factor of tobacco i.e. fresh weight of roots and stems, fresh weight of leaves, dry weight of chopped tobacco, and nicotine content
Profitability and Farmers Conservation Efforts on Sustainable Potato Farming in Wonosobo Regency
Get PDFIt takes into account in potato farming sustainability, since it was recognised as a holticultural commodity for farmers’ subsistence in Wonosobo Regency. For the reason that farming land was being degraded by errossion, the potato productivity apparently continued to decline. Potato farming sustainability can be deliberated from economic (profitability) and environmental (conservation efforts) points of view in order to remain profitable in a long term sustainable environment. This study is aimed to (1) to analyse the profitability of potato farming; (2) to analyse farmers’ effort on soil conservation and factors which affected sustainability of potato farming. The method used in this study was basic descriptive analysis. The study site was in Kejajar District, Wonosobo Regency, subsequently 50 random farmers as respondences was obtained. Gross Margin, Return on Invested Capital, and Operating Ratio were used to measure the profitability of potato farming. Conservation Activity Index (CAI) was used to measure farmers’ effort on soil conservation, while paired liner regression model with Ordinary Least Square (OLS) method was used to understand the factors which affected the conservation efforts of test sites. The study results revealed that the potato farming was profitable. Farmers conservation efforts mostly was in average category (74%), and only view in high category (16%) and low category (10%). Factors affected the farmers conservation efforts i.e. land area, potato products, potato price, the off-farm income, number of family members, farmers ages, and village dummy
Seleksi Varietas Partisipatif Terhadap Galur-Galur Elit Padi Gogo di Lahan Petani
Get PDFSalah satu indikator keberhasilan program pemuliaan adalah diadopsinya varietas unggul oleh petani. Meskipun pemulia memiliki kemampuan untuk memilih varietas-varietas terbaik, selera petani terhadap varietas unggul dapat berbeda dan sangat beragam antar daerah. Program seleksi varietas partisipatif (participatory varietal selection=PVS) dikembangkan untuk meningkatkan efisiensi seleksi yang dilakukan pemulia dengan melibatkan petani sebagai pengguna akhir produk pemuliaan dalam proses seleksi. Dua kegiatan seleksi varietas partisipatif dilakukan pada musim hujan 2012-2013 di dua sentra padi gogo yakni Cianjur (Jawa Barat) dan Kebumen (Jawa Tengah). Sepuluh galur harapan padi gogo dan empat varietas unggul pembanding digunakan dalam kegiatan PVS. Masing-masing galur atau varietas ditanam oleh seorang petani kooperator dengan luas tanam 2000 m2 sampai 2500 m2. Budidaya padi dilakukan oleh petani berdasarkan paket rekomendasi dari peneliti. Seleksi dilakukan pada saat menjelang panen dengan melibatkan sebanyak 20 sampai 22 orang petani di masing-masing lokasi. Hasil PVS menunjukkan keragaman preferensi petani di dalam dan antar daerah. Hasil penelitian ini mengindikasikan adanya kesesuaian antar nilai preferensi varietas hasil seleksi petani dengan nilai penerimaan fenotipe oleh pemulia. Namun demikian tidak semua genotipe dengan nilai preferensi yang tinggi menghasilkan gabah yang tinggi, mengindikasikan bahwa komponen hasil bukan satu-satunya penentu preferensi petani dalam mengadopsi varietas unggul. Dampak dari pelaksanaan PVS terhadap adopsi varietas unggul, peningkatan keragaman genetik di lapang dan sarana penyebaran benih informal didiskusikan dalam tulisan ini
Proline Activity and Growth of Oil Palm affected by Aluminium Toxicity and Silica as Ameliorant
Get PDFThe research aims to investigate the effects of silica (Si) as an ameliorant on the proline compound concentration and the growth response of oil palm exposed to aluminum toxicity. The research was arranged in a complete randomized block design with 8 blocks as replications. The first factor was Al toxicity which consisted of two levels as without and with Al toxicity. Al toxicity treatment was applied by giving 300 ppm of Al concentrate along with watering activity regularly. The second factor was the application of silica which consisted of four levels as 0, 32, 64 g/plant. Proline and growth activities of leaf area, plant height, number of leaves, and dry weight were observed in the research. The data subjected to analysis of variance (ANOVA) at 5% test level. If the result of ANOVA showed significant differences among treatments, then the data would have been analyzed by Duncan’s Multiple Range Test (DMRT) at 5% test level. The results of the research provide information that Al toxicity increases proline compound in the plant tissues and decreases leaf area, plant height, number of leaves, and dry weight of Oil Palm. Applying Si at the level of 64 g/plant could increase proline concentrate and dry weight of oil palm exposed to A1 toxicity. Proline compound in the plant tissues did not have any correlation with the growth of oil palm. Thus, this case indicated that proline was a product and not a plant tolerant mechanism of Al toxicity
