    Agriculture Conservation for Extreme Agricultural Practices to Minimize Runoff Harvesting at Gumuk Micro Catchment, Boyolali Regency, Central Java
    (Balai penelitian Agroklimat dan Hidrologi, 2013-06-01) Sosiawan, Hendri
    Most of the farmer in Gumuk Village, Boyolali Regency famous for the cultivation of high value crops such as vegetables, tobacco, rose and fennel. The cultivated land situated at an altitute about 15400 m above see level which the dominant step slopes to reach more than 45 % of Merapi Mountain as well as the upper part of upstream of Kali Pusur watershed. The common agricultural practicesof local farmer is traditional as well as parallel to the slope planting, low dosage of dung, compost and cemical fertilizer, and only a few farmers who grow roses and the fennel as a vegetative terrace. The consequences are high risk of erosion, land slide, sediment yield and runoff harvesting. The phenomenon will indirectly affect the hydrologic variability such as flash floods in the rainy season, sedimentation of the reservoirs and irrigation networks and declining on the recharge rate of aquifers that constitute the main water resource during dry season in the downstream area which is largely a food crop production center of Klaten regency

    BUDIDAYA PADI PADA LAHAN RAWA PANTAI TERDAMPAK SALINITAS
    (Balittra, 2021) Anisa, Wahida; Sosiawan, Hendri; Susilawati, Ani; Balai Penelitian Pertanian Lahan Rawa
    Tanah salin adalah tanah-tanah yang mempunyai nilai ESP (Exchangeable Sodium Percentage) 15 % atau lebih atau mempunyai SAR (Sodium Adsorption Ratio) 13 atau lebih dan seringkali mempunyai pH 8,5 atau lebih (Soil Survey Staff 2014). Tanah salin ini di jumpai di daerah rawa pasang surut yang berbatasan dengan garis pantai. Suasana salin akibat pengaruh air asin/air laut menyebabkan terbentuknya tanah pirit pada tanah mineral atau tanah gambut yang relatif tidak matang atau suasana tawar. Masalah salinitas terjadi ketika jumlah garam terlarut dalam tanah cukup tinggi. Penimbunan garam di daerah perakaran mempengaruhi terhadap kemampuan tanaman untuk menyerap air. Garam mempengaruhi pertumbuhan tanaman umumnya melalui: (a) keracunan yang diakibatkan penyerapan unsur penyusun garam secara berlebihan, seperti sodium, (b) penurunan penyerapan air, dikenal sebagai cekaman air dan (c) penurunan dalam penyerapan unsur-unsur penting bagi tanaman khususnya potasium. Gejala awal munculnya kerusakan tanaman oleh salinitas adalah: (a) warna daun yang menjadi lebih gelap daripada warna normal yang hijau-kebiruan, (b) ukuran daun yang lebih kecil dan (c) batang dengan jarak tangkai daun yang lebih pendek. Jika permasalahannya menjadi lebih parah, daun akan menjadi kuning (klorosis) dan tepi daun mati mengering terkena “burning” (terbakar, menjadi kecoklatan). Menurut FAO (2005) bahwa kisaran nilai salinitas (EC) tanah pada budidaya padi dan tingkat kehilangan hasil adalah: (1) EC < 4 dS/m, maka perkiraan kehilangan hasil tanaman < 10%, (2) EC > 4 dS/m, maka perkiraan kehilangan hasil tanaman 10-20%, (3) EC > 6 dS/m, maka perkiraan kehilangan hasil tanaman 20-50%, (4) EC > 10 dS/m, maka perkiraan kehilangan hasil tanaman > 50%.

    FOOD SMART VILAGE "Managing Land And Water Resources For Better Livelihoods Through Agriculture Development"
    (Balai penelitian Agroklimat dan Hidrologi, 2013-09-01) Sosiawan, Hendri
    Driest climate upland area in Indonesia such as part of South Sulawesi, East and West Nusa Tenggara where low yields, may become even less-suited for agriculture as a result of water scarcity and land degradation. These conditions become more severe during the climate change that occurring more rapidly than anticipated and the increase in extreme weather events threatens more disruptive effects to agriculture.

    Improving Irrigated Agriculture Through Integrated Water Resources Management In Klaten Regency: An Organizational Approach
    (Balai penelitian Agroklimat dan Hidrologi, 2013-03-31) Sosiawan, Hendri
    In developing countries as Indonesia, competition in water use for agriculture, industry and domestic purposes is increasingly tight often result in conflict. The unplanned population dynamic, population growth and settlement shift exacerbates the problems with increasing demand for industrial and domestic uses. Unfortunately, without the availability of appropriate data on supply and demand water allocation are increasing in the other sectors at the expense of agriculture. This condition will lead to conflict among water users. Farmers that produce food for all people in the country are very often become the losersin many negotiation among the stakeholders. The water supply is decreasing and more unpredictable due to decreasing the water retention capacity because of watershed degradation, and becoming less predictable because of climate change. While the demand are increasing because of population growth and developing economy and aggravated by urbanization to the urban areas downstreams. Klaten Regency is one of rice center production in Indonesia as a typical case of water sharing problem not only among the stake holder but also among farmer water users as well. The curiousity among the stake holder was triggered by the several water regional situation factors i.e. no rainfall and weak river flows during the dry season, disorganization of former collective management system, degradation of irrigation network, illegal water intake, lack of canal maintenance ets. The multi user of water resources and its spatial distribution of Klaten Regency. The decreasing water availability problems for rice field particulary in downstream area have caused the third growing season can not be implemented if there is no provision of supplementary irrigation from groundwater. Given that the issue of disputes between water users in the Klaten Regency become more frequent and more complex, CIRAD and IAHRI propose and take the initiative to develop a participatory approach intended for all stakeholders on the agreement a step towards the Integrated Water Resources Manamegent.

    Modern Irrigation To Support The Large Scale Agriculture Development
    (Balai penelitian Agroklimat dan Hidrologi, 2012-08-01) Sosiawan, Hendri
    Large scale agricultural development for food crops will only be successful if supported by best fit agricultural practices, including the application of modern irrigation.. Irrigation is the artificial application of water to the land or soil. It is used to assist in the growing of agricultural crops, maintenance of landscapes, and revegetation of disturbed soils in dry areas and during periods of inadequate rainfall. To reach targeted production a long the year, the water supply using the modern mechanized irrigation system is a must. The modern irrigation must supply water at rates, in quantities and at times needed to meet farm irrigation requirements and schedule. The most popular of the modern irrigation systems to support water supply at farm irrigation namelly Sprinkle Irrigation, Center Pivot Irrigation and Lateral Move Irrigator system.

    Panen Air Menuai Kesejahteraan Petani
    (IAARD Press, 2018) Sulaiman, Andi Amran; Setiawan, Budi Indra; Sosiawan, Hendri; Kartiwa, Budi; Torang, Syamsir; Aquino, Foyya; Saputro, Septian Dwi Fauzi
    Air merupakan satu komponen kunci dalam produksi pertanian. Air berperan dalam melarutkan hara dan oksigen kemudian membawanya ke sekitar perakaran. Pada lahan kering, ketersediaan air sering kali menjadi masalah utama. Buku ini membahas secara komprehensif tentang konsep panen air (water harvesting) dan penyalurannya ke lahan-lahan pertanian. Pemerintah berperan besar dalam penyediaan air ini, seperti ditunjukkan oleh program pengembangan empat juta hektare lahan kering. Buku ini juga membahas secara tuntas aneka infrastruktur air, seperti embung, long storage, dam parit, dan bangunan air lainnya, lengkap dengan desain fisik, manfaat, dan anggarannya. Aplikasi konsep panen air telah dicontohkan di beberapa tempat yang menunjukkan bagaimana perbaikan dan pembuatan infrastruktur air dapat mendongkrak pendapatan petani. Selain infrastruktur air, buku ini juga membahas bagian penting dalam distribusi air panen, serta aneka teknik irigasi mulai dari irigasi tetes, irigasi berselang, hingga irigasi curah dengan big gun sprinkle. Semua hal tersebut membuat buku ini layak menjadi rujukan utama bagi mahasiswa, pengambil kebijakan, investor, hingga masyarakat umum tentang bagaimana memanen air dan menyalurkannya ke lahan pertanian untuk mendongkrak produksi pertanian dan kesejahteraan para petaninya.
