Abstract

Abstrak. Lahan kering di Indonesia cukup potensial untuk dikembangkan sebagai lahan pertanian ditinjau dari segi luasan. Luas lahan kering di Indonesia mencapai lebih dari 140 juta ha. Lahan kering adalah lahan yang hanya mengandalkan air hujan sebagai sarana pemenuhan kebutuhan airnya. Ketidak pastian iklim di daerah ini, dengan adanya perubahan iklim, merupakan salah satu kendala dalam sistem produksi pertaniannya. Oleh karena itu penggunaan air secara efisien merupakan perhatian utama dalam usaha pertanian di lahan kering. Irigasi suplemen merupakan salah satu teknologi yang memfasilitasi pemenuhan kebutuhaan air sesuai kebutuhan tanaman dengan tingkat efisiensi penggunaan air yang berbeda tergantung jenis teknologi yang digunakan. Makalah ini bertujuan untuk mengemukakan tentang prospek implementasi teknologi irigasi suplemen untuk adaptasi perubahan iklim di lahan kering berdasarkan: 1) Prinsip dasar irigasi di lahan kering, 2) Potensi sumberdaya air di lahan kering, 3) Alternatif teknologi irigasi suplemen di lahan kering dan 4) Strategi implementasi teknik irigasi suplemen untuk usahatani di lahan kering.Abstract. Upland is the land that only depend on the rainfall as the main water source to fullfill its water needs. Unpredictable climate in this area, even with climate change appereance, is one of the problem/constraint in its agriculture production. So that, water use efficiency should become the main concern on farming system practise in upland. Suplemental irrigation is one of technology that facilitate to fullfill water needs as well as crop water requirement with different water use efficiency level, depend on the kind of technology that be used. This paper was aim to inform about the implementation prospect of suplemental irrigation technology for adaptation of climate change in upland base on: 1) Principle of irrigation in upland, 2) Potential water source in upland, 3) Alternatives of suplemental irrigation technology in upland and 4) Strategy of suplemental irrigation technology implementation for farming system in upland.

Abstract

Abstrak. Biochar merupakan material baru yang diteliti secara intensif dalam waktu sepuluh tahun terakhir di berbagai penjuru dunia. Hal ini dipicu oleh fakta bahwa tanah-tanah Terra Preta di wilayah Amazon, Amerika Selatan, dikenal sangat subur karena mengandung arang yang dibentuk dari pembakaran minim oksigen (pirolisis) ribuan tahun yang lalu. Dalam kondisi kemajuan teknologi seperti sekarang ini para peneliti mencoba untuk meniru dalam memperoleh material serupa yang kemudian dikenal secara luas dengan istilah biochar dan menguji manfaatnya terutama untuk perbaikan kondisi tanah agar menghasilkan pertumbuhan dan produksi tanaman yang lebih baik, sekaligus mampu menjadi penghambat lepasnya karbon ke atmosfir (carbon sequestering). Sebagai sebuah topik riset yang baru tentu saja dapat dipahami bahwa hal tersebut menimbulkan pro- dan kontra, khususnya yang menyangkut manfaat positif secara luas. Pihak yang pro mendasarkannya pada banyak bukti tentang manfaat aplikasi biochar terhadap pertumbuhan dan produksi tanaman seperti halnya juga terhadap sifat-sifat tanah. Sebaliknya yang kontra menekankan terbatasnya data yang tersedia sejauh ini dan adanya ketidak-konsistenan hasil yang dilaporkan. Ulasan berikut ini mencoba untuk melihat dari dua sudut tersebut untuk memberikan gambaran yang sebenarnya bagi para calon peminat riset dan/atau pengguna biochar untuk kepentingan perbaikan kesehatan dan produktivitas tanah. Pada akhir diskusi disampaikan perlunya persyaratan mutu biochar untuk memperoleh hasil yang dapat diperbandingkan.Abstract. Biochar is a new material researched intensively within the last ten years in various parts of the world. This is fuelled by the fact that the lands of Terra Preta in the Amazon region of South America is known to be very fertile because it contains charcoal that was formed from the minimum oxygen combustion (pyrolysis) at times thousands of years ago. Under the conditions of technological advances like nowadays, researchers tried to replicate it in obtaining similar material which was then widely known by the term biochar and test its usefulness mainly to improved soil conditions in order to generate growth and better crop production and the same time capable of being a barrier to the release of carbon into the atmosphere (carbon sequestering). As a new research topic, it is understandable that it raises pros and cons, especially on its benefits. The pro-side emphasized on the proven beneficial application of biochar to improve growth and yield of crops as well as on soil properties. Others, rised the controversy focused on the limited data reported and somewhat inconsistency on the results. The following review is trying to look at it from the two angles to give the real picture for the prospective applicants of biochar such as researchers and users of biochar for the benefit of improving health and productivity of the soil. At the end of the discussion it is given the necessity for quality standard of biochar to obtain comparable results.

Abstract

Abstark. Lahan kering merupakan lahan yang dapat digunakan untuk pengembangan pertanian masih  sangat luas. Diperlukan optimalisasi pertanian lahan kering agar dapat meningkatkan produksi pertanian menuju target jangka panjang menjadi lumbung pangan dunia. Kendala utama pada lahan kering beriklim kering adalah ketersediaan air yang terbatas, sehingga perlu optimalisasi penggunaan air dari sumber air yang tersedia, baik air permukaan (air sungai, embung/danau) maupun air tanah dalam, yaitu melalui irigasi hemat air. Irigasi hemat air dapat meningkatkan layaran irigasi, berarti dapat meningkatkan indeks pertanaman atau meningkatkan luas tanam sehingga produksi pertanian meningkat. Permasalahan irigasi hemat air dalam pengembangannya adalah dari sisi manajemen atau pengelolaannya, mulai dari pemeliharaan bangunan infrastruktur air dan sumber air sampai masalah pemanfaatan dan pendistribusian air. Teknologi irigasi hemat air yang diterapkan prinsipnya berdasarkan kebutuhan air minimum dalam tanah. Irigasi diberikan sesuai dengan kebutuhan minimum air tanaman yaitu lebih rendah dari kebutuhan yang biasa diberikan. Adanya masalah dalam pengembangan irigasi hemat air terkait sumber air yang melintasi wilayah berbeda memerlukan solusi yang tepat. Demikian juga dalam pemeliharaan bangunan infrastruktur air dan sumber air memerlukan perhatian bersama. Oleh karena itu, diperlukan peningkatan atau membentuk kelembagaan petani baru yang mengurus pengelolaan air irigasi untuk mengatur penggunaan air irigasi, memelihara infrastruktur air dan memelihara sumber air serta mengurangi bahkan menghindari konflik perebutan penggunaan air pada saat air untuk tanaman diperlukan dan jumlah air terbatas dengan menerapkan conflict management.

Abstract

Rice soils derived from alluvial deposite were spread almost in all Indonesian archipelago, due to the fact that the parent materials were resulted from sedimentation processes after erosion or weathering either in the upper course of river or the higher place, from the far or short distance. Generally the more distance of sediment material from the source of erosion or weathering, the more variation in the properties, and the closer of sediment material from the source of erosion or weathering, the more homogeny of the sediment material properties. The content and kind of weatherable mineral which were act as important source of nutrient inthe rice soils were influenced by parent materials. Among the parent materials, the sediment from intermediate to basic volcanic materials was the best supplier of nutrients. The most constrain in the alluvial rice soils are acidity and the nutrient content or source of nutrients. A balanced fertilizing based on soil testing is the best way to manage alluvial rice soils. For the area which is already had P and K nutrient status map at 1:50,000 scale, the fertilizing recommendation of primer macro nutrients could be refered to the map, while for the area that do not has a P and K nutrient status, the soil testing analyses should be done. Return straw to the ricefield is strongly recommended, because returned straw could be thrifty application of fertilizer, especially kalium (K).

Abstract

Abstrak. Pestisida memegang peranan penting dalam mempertahankan hasil tanaman tinggi. Namun penggunaannya yang tidak tepat menimbulkan dampak negatif terhadap lingkungan. Akumulasinya di dalam tanah, air, dan produk pertanian yang melebihi kadar batas maksimum residu akan menurunkan kualitas lingkungan dan kesehatan manusia. Salah satu upaya mitigasi residu pestisida adalah ameliorasi dengan menggunakan arang aktif yang bahannya dapat berasal dari limbah pertanian. Arang aktif efektif menurunkan residu pestisida dalam tanah dan produk pertanian, baik pestisida organoklorin, organofosfat, ataupun karbamat. Pemberian arang aktif dari tempurung kelapa dan tongkol jagung baik dengan atau tanpa diperkaya mikroba konsorsia efektif menurunkan kadar residu lindan dan aldrin di tanaman sawi.Abstract. Pesticide plays an important role in maintaining high crop yields. However, its inappropriate use affects negative impact on the environment. Its accumulation in soil, water, and agricultural products that exceed the maximum residue limit will reduce environmental quality and human health. Amelioration using activated charcoal is one of efforts to mitigate pesticide residues. Activated charcoal materials can be derived from agricultural wastes. Activated charcoal effectively reduces pesticide residues in soil and agricultural products, either organochlorine pesticides, organophosphates, or carbamates. Application of activated charcoal from coconut shell and corn cob with or without enrichment with microbial consortia effectively reduce the levels of lindane and aldrin residues in vegetable plants such as mustard.

Abstract

In West Nusa Tenggara Province, natural pasture is one of important forage sources for cattle feed. Due to its agroclimate condition, carrying capacity of the native pasture is usually low. Wider variation has been observed between wet and dry seasons, and it has significant effects to cattle population. Based on the issue, a medium term of land management by introducing of silvopasture combined with legume trees, high yielding varieties of grasses, and fast growing leguminous shrubs, has been done during 1995/96-1998/99 period. The aim of the research was to increase carrying capacity of the natural pasture based on the improvement of microclimate condition, soil properties, and carrying capacity. The experiment used split-plot design with three replications. Implementation of silvopasture in the form of wind breaker (WB) and non wind breaker (NWB) are as main plot, carrying capacity estimation (grazing and cut systems) as sub plot, while introducing high yielding varieties of grasses and fast growing legume as sub-sub plot. Observation during four years showed that silvopasture could improve microclimate conditions indicated by decreasing of air temperature from 27.9-40.0oC into 22.0-38.9oC, increasing of air humidity from 62.6-93.6% into 77.1-89.1% and decreasing of saturation steam pressure deficit from 3.4-26.3 into 0.5-14.8. Soil organic matter increased almost 200% on the 3rd year and soil nitrogen increased almost 300% on the 4th year of experiment. Silvopasture system (wind breaker treatment) could increase carrying capacity grass land that varied from 1.16 to 1.75 animal unit (AU) of cattle/ha/year, while carrying capacity of non wind breaker varied from 1.10 to 1.37 animal unit (AU) of cattle/ha/year.

Abstract

Available water resources and its quality in Indonesia have been deteriorated as an impact of climate change (and/or) environmental degradation. This could affect on farming processes particularly and agricultural development in general. Virtual available surface water gives a figure that available water decreased temporally and spatially. For instance, in Java island with cover 65% of total population only has 4.5% of the total available water in the country. Agriculture is the biggest use of water (about70%), but it will be difficult for farmers to accomplish water requirements. Other users such as domestic (about 6%), industry (about7%), and municipal (about 4%) are also the major users of water in the country, which may raise a conflict among the users in covering the needs. Current mechanisms to cope climate change in water resources management has been executed through adaptation and mitigation measures for supporting farming system. Integrated water resources management plays critical role in coping climate change. This includes prioritizing water requirements, water harvesting, water conservation, appropriate water allocation, and pollution control. For sustainable farming system development, mitigation strategy should also be included in themechanism covering practices of intermittent irrigation to over come high rate of methane emission. Combining water management and tolerance crops to drought and submergence conditions is very valuable in implementing the mechanisms.

Abstract

Abstrak. Ultisol merupakan salah satu tanah tua, terdapat horizon argilik/iluviasi yang padat, mengalami pencucian intensif, tanah lapisan atas tipis, kesuburan rendah, dan tanah banyak mengalami degradasi. Sejalan permasalahan tersebut, upaya rahabilitasi tanah Ultisol terdegradasi di kawasan megabiodiversity seperti halnya di Indonesia dapat diupayakan dengan pemberdayaan sumberdaya hayati tanah. Fauna tanah yang mampu membuat liang di dalam tanah dapat mengurangi erosi dan pencucian hara, mikroba pelarut P dapat meningkatkan ketersediaan P tanah, mikroba penambat N2-bebas dapat meningkatkan ketersediaan hara N tanaman, dan pengkayaan populasi organisme tanah lainnya untuk meningkatkan daur hara dan konservasi C-organik tanah. Untuk mewujudkan peranan organisme tanah tersebut perlu diikuti pemberian bahan organik ataupun pupuk sebagai sumber hara dan energi, serta pengendalian jenis dan jumlah populasi organisme tanah yang memiliki peranan penting dalam memperbaiki kesuburan tanah sesuai dengan target perbaikan yang diharapkan.Abstract. Ultisol is one of the highly weathered soils, with solid agrillic or illuvial horizon, intensive leaching, a thin top layer, low fertility, and a lot of soil degradation. Along these problems, attempts to rehabilitate degraded Ultisols in megabiodiversity areas like Indonesia could be performed by empowering soil biological resources. Soil fauna having ability to create soil pores could reduce erosion and nutrient leaching, microbes have ability to dissolved P and P-availability, microbes able to fix N2 from atmosphere to increase soil nutrient, and the enrichment of populations of other soil organisms to improve nutrient cycling and soil C-organic preservation. To achieve the role of soil microorganisms, it is necessary to apply organic matter as sources of nutrients and energy, controlling the type and number of populations of soil organisms which have an important role in improving soil fertility according to the expected targets.

Abstract

Abstrak. Lahan pertanian menyumbangkan emisi gas rumah kaca (GRK) melalui beberapa proses. Skala global dan nasional, perhitungan besaran emisi GRK telah banyak dilakukan, baik dalam bentuk studi ilmiah maupun laporan nasional terkait status dan emisi di suatu negara. Inventarisasi GRK dalam skala kawasan, mencakup pengumpulan serta pembangunan data aktivitas, penentuan sasaran penurunan emisi pada penyumbang emisi utama serta membandingkan hasil perhitungan metode IPCC 2006 dan metode modifikasinya. Sumber emisi GRK utama berdasarkan jenis gas di dua kabupaten adalah gas CH4 (pengelolaan lahan sawah, fermentasi enterik dan pengelolaan kotoran ternak) yaitu sebesar > 50% (dalam CO2e). Total emisi GRK Kabupaten Grobogan dan Tanjung Jabung Timur dari tahun 2006-2011 dengan menggunakan metode IPCC 2006 adalah sebesar 678-758 Gg CO2e dan 543-659Gg CO2e, sedangkan dengan menggunakan metode IPCC 2006 modifikasi adalah sebesar 670-744 Gg CO2e dan 540-658 Gg CO2e. Emisi ini diperkirakan akan terus meningkat mencapai angka 898 Gg CO2e dan 820 Gg CO2e di tahun 2020 jika tidak ada aksi mitigasi. Total emisi di kedua provinsi dengan menggunakan metode IPCC 2006 asli dan modifikasinya hanya berbeda sebesar 1%. Modifikasi metode yang dilakukan pada perhitungan emisi N2O langsung dari tanah sawah irigasi bisa digunakan karena lebih mudah dan sederhana dalam pengumpulan data aktivitas dan perhitungannya.Abstract. Agricultural land contributes to greenhouse gas(GHG) emissions through several processes. In global and national scale, GHG emissions have been presented in scientific studies and national reports. Regional inventory mostly gathered and generate activity data, define mitigation action to main emission contributors and to compare original and modified IPCC 2006 Guidelines. CH4 emissions (rice cultivation, enteric fermentation and manure management) was the main contributor to overall GHG emissionsin the two districts with the amount of > 50% (in CO2e). Overall Grobogan and East Tanjung Jabung GHG emissions from years 2006-2011 using IPCC 2006 was 678-758 Gg CO2e and 543-659 Gg CO2e respectively and overall GHG emissions using modified IPCC 2006 was 670-744 Gg CO2e and 540-658 Gg CO2e. This emission in Grobogan and East Tanjung Jabung were expected to continue rising and reach the figure of 898 Gg CO2e and 820 Gg CO2e in 2020 if no mitigation actions implemented.The result of IPCC 2006 and it?s modification method was only 1% different in overall GHG emission in two region. The modification method to direct N2O emission from irrigated rice could be used because it?s simpler and easier both in gathering activity data and the calculation itself.
