Abstract

Salah satu wilayah pertanian aktif di Kabupaten Bangkalan adalah Desa Pandanan. Tingginya potensi degradasi lahan di Desa Pandanan menjadikan upaya mitigasi degradasi lahan harus segera dilakukan. Salah satu upaya yang dapat dilakukan adalah melalui pengabdian kepada masyarakat (abmas) oleh tim dari Institut Teknologi Sepuluh Nopember dan Badan Riset Inovasi Nasional terkait optimasi kesuburan lahan pertanian. Kegiatan abmas yang dilakukan berfokus pada tiga tahap utama yakni: (1) Sosialisasi/penyuluhan terkait pentingnya optimasi kesuburan lahan pertanian berbasis data (satelit dan validasi lapangan), (2) penyuluhan/sosialisasi terkait penggunaan pupuk organik berbahan dasar limbah peternakan lokal Desa Pandanan, dan (3) pelatihan serta pendampingan pembuatan pupuk organik. Hasil sosialisasi dan pelatihan menunjukkan bahwa kelompok tani Harapan Jaya 1, Desa Pandanan mampu mengolah limbah peternakan setempat menjadi pupuk organik, dengan adanya kegiatan ini diharapkan dapat meningkatkan pengetahuan, keterampilan, kemandirian petani dan masyarakat terhadap input pertanian, sehingga dapat mengoptimalkan kesuburan tanah seiring waktu dengan mengurangi penggunaan pupuk kimia yang memiliki potensi mencemari lingkungan khususnya lahan pertanian. Kedepan secara bertahap diharapakan dapat meningkatkan produktivitas lahan pertanian dan ekonomi yang berdampak pada kesejahteraan masyarakat khususnya para petani Desa Pandanan Kabupaten Bangkalan.

Abstract

Kegiatan pengabdian masyarakat yang dilakukan di Desa Bendosari, Blitar ini bertujuan untuk meningkatkan efisiensi dan kualitas produksi pakan ternak melalui teknologi modern. Tantangan utama yang dihadapi adalah penyumbatan mesin pencacah pakan ternak dan kesesuaian media tanam untuk perkecambahan Indigofera. Solusi yang diterapkan mencakup pengembangan mesin pencacah dan pelet pakan ternak, analisis media tanam optimal untuk Indigofera skala laboratorium, dan pelatihan penggunaan mesin serta budidaya Indigofera. Tujuan kegiatan ini adalah untuk meningkatkan efisiensi produksi pakan dan keterampilan petani dalam menggunakan teknologi baru, serta menentukan media tanam terbaik untuk Indigofera. Mitra yang terlibat dalam kegiatan ini adalah Kelompok Tani Ben Giat Tani sebagai pengguna teknologi dan peneliti dari BRIN yang berkontribusi dalam penelitian media tanam dan uji tanah. Pelatihan dan modul operasional disediakan untuk meningkatkan keterampilan petani. Kegiatan ini mendukung Tujuan Pembangunan Berkelanjutan (SDGs) dengan meningkatkan produksi pangan (SDGs 2), pekerjaan layak dan pertumbuhan ekonomi (SDGs 8), inovasi industri (SDGs 9), konsumsi dan produksi yang bertanggung jawab (SDGs 12), serta konservasi ekosistem darat (SDGs 15).

Abstract

Rice field is issued as a source of greenhouses gases (GHGs) emissions especially methane (CH4) and nitrous oxide (N2O). Rice cultural approach could mitigate GHGs emissions i.e. through rice planting systems and nematicide application. The field experiment was conducted in rainfed rice field at Pati District, Central Java to determine effect of planting systems and nematicide application on emissions of methane and nitrous oxide from rainfed rice field. The six treatments were arranged in a randomized block design with three replicates, namely transplanted rice (TR) without applying nematicide, TR + neem cake, TR + carbofuran, direct seeded rice (DSR) without applying nematicide, DSR + neem cake, DSR + carbofuran. Parameters observed were methane flux, nitrous oxide flux, organic C content in rhizosphere, soil pH, soil redox potential surrounding rhizosphere of Ciherang variety. Methane emission under transplanted rice system was generally higher than direct seeded rice system.  The treatment of DSR + neem cake resulted lowest methane emission (71 kg CH4 ha-1 season-1). The TR system emitted N2O lower significantly than the DSR system. Application of nematicide inhibitor materials decreased more effectively N2O emission. The DSR system increased significantly grain yield and N uptake, while application of nematicide materials didn’t increase grain yield but increased significantly N uptake.

Abstract

Nitrogen fertilizer use in rainfed rice fields is generally less efficient, only part of N is taken up by plants for their gowth and other N is lost and fixed by soil particles. Nitrogen loss in the form of nitrous oxide can reduce N fertilizer use efficiency and contribute to the increase of atmospheric greenhouse gases emission. The field experiment was conducted to determine the residual effect of N fertilizer on nitrous oxide (N2O) flux and yield of some cowpea varieties (Vigna unguiculata) in rainfed rice fields. The experiment was arranged in a factorial randomized block design with three replicates. The first factor was three cowpea varieties (KT 9, KT 6, KT 3), while the second factor was four levels of residual inorganic N fertilizer (0, 90, 135, 180 kg N ha-1). The variables measured were N2O fluxes, grain yield, biomass weight, total N content in soil before planting cowpea, available N in soil after harvesting cowpea. Residual N fertilizer increased significantly N2O emission from cowpea cropping. Nitrous oxide emission from plots grown with cowpea variety of KT 9, KT 6, and KT 3 ranged 0.42-0.69, 0.30-2.64, and 0.09-2.19 kg N2O ha-1, respectively. N losses from soil grown with KT 9 was lower than those in plots grown with other varieties. Residual effect of N fertilizer increased available N in soil as much as 11.6-82.3% (KT 9), 7.6-30.6 % (KT 6), and 9.6-67.9% (KT 3), recpectively. Residual effect of N fertilizer increased significantly grain yield of KT 9, KT 6, and KT 3 varieties as much as 45.7-111.8%, 79.8-89.3%, and 6.9-25.4%, respectively.
