Analisis Efisiensi Teknis USAhatani Padi Sawah Irigasi di Kabupaten Seram Bagian Barat

The Analyzes of Technical Efficiency on Rice Farming in West Seram District. The study has been done on technical irrigated land in the district of West Seram (SBB), Maluku Province. This study aims to analyze the factors affecting rice production and the level of technical efficiency and the factors affecting technical efficiency on irrigated land. Method of Maximum Likelihood Estimation (MLE) is used to estimate the parameters of the stochastic frontier production function in the form of Cobb-Douglash and linear regression with OLS method to estimate the determinants of technical efficiency. The results showed that there are three independent variables that significantly positive affect the output are Urea, NPK pelangi, and labor. Average level of technical efficiency 0.869 (range 0.684 to 0.967), by applying appropriate skills and cultivation techniques in the most efficient farmers average farmer will be able to save the cost of 10.16%. Factors area and transplanting system has positive significant effect on the level of technical efficiency of rice farming

Kajian Pengelolaan Hara Spesifik Lokasi Padi Sawah Irigasi di Kabupaten Buru

Assessment on Site-Specific Nutrient Management of Irrigated Rice in Buru Region. Recommended dose of package fertilize which is widely applied by administrative boundaries or district is less appropriate with principles of site-specific nutrient management (SSNM). Fertilizer recommendations should be based on soil fertility status (SFS) and plant responses to fertilization in a specific yield target. Analysis spatial data are available online with Geographic Information Systems (GIS) can be used in a rapid, inexpensive and relatively accurate to help map SFS and fertilizer recommendations. The purpose of this study was to determine the dose and N, P and K fertilizer recommendation maps for paddy on each SFS mapping unit in Waeapo Plains, Buru. Omission plot trials were conducted at 12 locations. Mapping fertilizer recommendations were made by spatial analysis using software Krigging Interpolator of ArcView GIS. The results showed that the target of sustainable rice yield ranged from 6.40 to 6.75 t paddy/ha. The need for fertilizer N, P and K on lowest SFS is 120.20 kg N/ha, 13.03 kg P/ha and 58.12 kg K/ha. While at low SFS is 136.53 kg N/ha, 13.46 kg P/ha and 58.97 kg K/ha. The areas were divided into five fertilizer recommendations based on SFS and target sustainable yield rice namely SR-I 14,830.02 ha area; SR-II covering 4,722.42 ha; R-I covering 3,763.67 ha, R-II covering 1,022.11 ha and R-III with an area 1510.60 ha. Analysis of satellite imagery with GIS can be used to map the SFS and site-specific fertilizer recommendations in a rapid, inexpensive and accurate

Land Suitability and Proposed Land Utilization of Selaru Island, West Southeast Moluccas Regency for Development Food Crops

The study was conducted in Selaru Island, West Southeast Moluccas Regency in an area of   32,217 ha. The research objective was to determine the land suitability and proposed land utilization of Selaru Island for development of food crops. The results showed that Selaru Island has a rather suitable (S2) and marginally suitable (S3) for six crops (upland rice, corn, peanuts, mungbeans, sweet potato, and caladium) covering an area of   19,330 ha and not suitable permanent (N2) for the six crops covering an area of   3,905 ha, while the area of   8,982 ha partly classified accordingly (S3) to plant upland rice and calladium and partially classified as not suitable (N1 and N2) for corn, peanuts, mungbeans, and sweet potatoes. The main limiting factor to the primary land use for food crops in Selaru Island, West Southeast Moluccas Regency among others are the temperatures (the average annual temperature is high), rooting medium (soil solum is shallow), nutrient retention (soil pH is rather alkaline to alkaline), erosion hazard level is moderate, and terrain (wave, rocks on the surface of the soil, and rock outcrop).The proposed land utilization of Selaru Island for food crops based on land suitability classes are (1) food crops of upland-1 with the main commodities of corn, mungbeans, uwi/kumbili and caladium an area of   5,299 ha, (2) food crops of upland-2 with the main commodities of upland rice, uwi/kumbili and caladium an area of   8,982 ha, and (3) food crops of upland-3 with the main commodities peanuts and mungbean an area of   14,031 ha. Development of food crops in Selaru Island need to consider the priority scale factor, the level of compliance, and social culture of the local community

Kajian Pemberian Pupuk Npk pada Beberapa Varietas Unggul Padi Sawah di Seram Utara

The assessment was conducted to 4 newly pre-eminent varieties of rice that aimed at knowing t performance of growth and potential yields on lowland rice irrigation at North Seram. The treatment w conducted on a 4—ha of farmer\u27s land by involving 8 cooperator farmers and 7 non cooperator farmers as comparison. The dosage of fertilizer used by cooperator farmers consists of 300 kg NPK Pelangi and 11 kg Urea/ha. The research was done from June 2006 until October 2006. The results indicate that the fo varieties of pre-eminent that were assessed, they are Fatmawati, Way Apo Buru, Gilirang and Ciherang I using NPK Pelangi, gives a higher average results of the growth and yields. The average yield of grains obtained was 6.44 ton — 8.20 ton GKP / ha which was higher 21 - 54% compared to the average yield grain obtained from farmers outside the assessment (non cooperator farmers) which was 5.30 ton GKP/ h The NPK Pelangi Fertilizer can be used to replace the single fertilizer in case the scarcity of fertiliz occurs since it provides high enough yields. From the four varieties assessed, for further development rice in North Seram it is recommended to employ Ciherang and Way Apo Buru varieties. Key words: NPK Fertilizer, pre-eminent variety newly, lowland rice, North Seram Telah dilakukan kajian terhadap 4 varietas unggul baru padi sawah yang bertujuan untuk mengetahui keragaz pertumbuhan dan potensi hasilnya pada lahan sawah irigasi di Seram Utara. Kajian dilakukan pada lahan milik petal seluas 4 ha dengan melibatkan 8 petani kooperator, dan sebagai pembanding adalah 7 petani non kooperator. Takan pupuk yang digunakan petani kooperator adalah 300 kg NPK Pelangi dan 100 kg urea/ha. Kajian berlangsung da bulan Juni sampai Oktober 2006. Hasil kajian menunjukkan bahwa keempat varietas unggul yang dikaji, yail Fatmawati, Way Apo Buru, Gilirang dan Ciherang dengan menggunakan pupuk NPK Pelangi, rata-rata memberik pertumbuhan dan hasil yang cukup tinggi. Rata-rata hasil ubinan yang diperoleh 6,44 ton — 8,20 ton GKP/ha, leb tinggi sekitar 21 — 54% dibandingkan dengan hasil gabah yang diperoleh petani di luar kajian (petani non kooperator yaitu 5,30 ton GKP/ha. Pupuk NPK Pelangi dapat digunakan sebagai pengganti pupuk tunggal jika terjadi kelangkaz pupuk karena dapat memberikan hasil yang cukup tinggi. Dari keempat varietas yang dikaji, untuk pengembangz lebih lanjut di wilayah Seram Utara disarankan menggunakan Ciherang dan Way Apo Buru
