Kebijakan Antisipatif Pengembangan Mekanisasi Pertanian

Pertumbuhan dan perkembangan mekanisasi pertanian diulas secara komprehensif sebagai bahan untuk melakukan analisis kebijakan pengembangan mekanisasi pertanian di Indonesia. Isu utama yang dibahas adalah fenomena pertumbuhan, praktek bantuan alsintan, dan masukan bagi kebijakan antisipatif pengembangan mekanisasi pertanian di Indonesia. Pertumbuhan mekanisasi pertanian memiliki korelasi timbal Balik dan signifikan terhadap kemajuan intensifikasi USAhatani, atau perbaikan mutu intensifikasi. Selama kurun waktu lebih dari dua dasa warsa (1990-2010), banyak pembelajaran kualitatif perkembangan mekanisasi pertanian yang bermanfaat, yaitu: (a) kekayaan sumberdaya; (b) keragaman teknologi, (c) keberadaan kelembagaan; dan (d) pranata sosial budaya, yang keempatnya memperkaya proses pertumbuhan mekanisasi pertanian. Fakta kuantitatif yang juga penting adalah pemilahan wilayah pengembangan mekanisasi menjadi empat kuadran, yang masing-masing mencirikan kontribusi tenaga per satuan luas (hp/ha), produktivitas dan nilai IP pertanaman padi. Pembelajaran kualitatif dan pemilahan wilayah mekanisasi pertanian dapat dijadikan dasar bagi pengambil kebijakan untuk melakukan revitalisasi bantuan alat dan mesin pertanian serta memberikan pendampingan pasca bantuan, sehingga dapat mempercepat proses adopsi alat dan mesin pertanian

Pengembangan Konsep Sistem Operasi dan Pemeliharaan (O&p) Daerah Irigasi Multiguna dengan Membangun Komitmen untuk Berbuat Konsensus Antar Pelaku : sebuah Kasus di Jawa Timur

On May 2006, the Government of Republic Indonesia launched the Government Rule (GR) no 20/2006 on irrigation. This GR replaced the previous GR no 77/2001 in the same issue. The changing of GR means also changing of implementation policy. Some constraints problems occurred and came up to hamper policy implementation in the field. Most of them mainly related to the changing of institution structure. The paper aims to discuss how local government and Gadjah Mada University try to solve the problems by developing a concept of solution. In this connection a discussion forum among stakeholder was set up. In the forum, university as a neutral scientific institution does as facilitator. The concept was tried to be implemented in two multipurpose irrigation schemes i.e. Bondoyudo and Siman, respectively in the multi year's basis. Those two schemes had several problems in irrigation management; one of them was conflict among users. In the first year some commitments and consensuses had already achieved by all stakeholders and would be implemented in the following years

Kesesuaian Hubungan antara Jenis Pompa, Sumber Air, dan Tanaman yang Dialiri

The research was conducted at Belawa, Wajo, South Sulawesi during dry season 011994/1995. Furrow irrigation system was used on the research. Axial type pumps were used to lilt water from creek at depths of 2 m, whereas centrifugal type pumps lifted water from the shallow well groundwater at depths of 15 m. Both type of pumps were used to irrigate soybean and maize crops with the total area for each plot of 500 m2. Maize and soybean were irrigated using furrow. Axial pump diameters and engine powers during the research were the following: 4" (6 HP), 6" (8 HP), and 8" (10 HP) respectively; while 2" (4 HP), 3" (5 HP), 4" (10 HP) for centrifugal pump. Objective of the research was to optimize benefit income from pump operations based on type of pump, irrigation type, source of water, land preparation, type of crop (s), irrigation efficiency, and yield. Results of the research shows that optimum performance among the centrifugal pump was achieved by pump diameter of 4" with optimum discharge 11.8 1/s, furrow length of 110 m, and cost of water Rp. 85.555, /season. Centrifugal pump type is suitable for soybean crop irrigation. Optimum benefit for axial type pump was obtained by PS-1 with the discharge of 35 Vs, length of furrow 180, cost of water Rp. 40.650,-/season, and suitable for maize irrigatio
