Abstract

Soil fertility problems in Wai Ela Negeri Lima are caused by 1) natural factors such as geology, soil, topography, and land uses; 2) land management system, such as shifting cultivation and deforestation; and (3) land degradation due to a natural disaster such as the fast flood in Wai Ela watershed. The objectives of the study were 1) to study soil chemical and physical characteristics of Wai Ela watershed; 2) to determine the soil fertility status of Wai Ela watershed; and 3) to provide some recommendations to improve the soil fertility. Soil properties used in determining soil fertility status included CEC, BS, C-organic, available P2O5, N-total, pH, soil depth, soil textures, and soil permeability rates. The soil fertility status was determined by using PPT’s criteria. Data preparation and analysis were conducted by using Geographic Information System. The study results showed that the soil fertility status of Wai Ela watershed ranged from the low-class 217.74ha (14.50%) to medium class 899.56 ha (60.21%) and high-class 303.35ha (20.31%). The recommended soil fertility status improvements in Wai Ela include balanced-fertilization management, increasing soil organic matter by applying manure and compost at soil tillage stage, neutralizing the soil pH and applying irrigation water management. Keywords: chemical and physical aspects, Negeri Lima, soil fertility, Wai Ela Watershed ABSTRAK Masalah kesuburan tanah di DAS Wai Ela Negeri Lima disebabkan oleh: 1) faktor alami yaitu geologi, jenis tanah, topografi dan penggunaan lahan; 2) pola pemanfaatan lahan, yaitu perladangan berpindah dan penebangan hutan; dan 3) degradasi lahan akibat bencana alam berupa banjir bandang di danau Wai Ela. Penelitian ini bertujuan untuk: 1) Mengkaji data kimia dan fisika tanah di DAS Wai Ela; 2) Menetapkan status kesuburan tanah di DAS Wai Ela; dan 3) Menentukan arahan perbaikan kesuburan. Sifat kimia tanah yang berpengaruh terhadap penetapan status kesuburan tanah adalah KTK, KB, C-organik, P2O5 tersedia, N total dan pH tanah. Sifat fisika tanah seperti kedalaman tanah, tekstur dan laju permeabilitas tanah. Penentuan status kesuburan tanah ditetapkan berdasarkan kriteria penentuan tingkat kesuburan tanah PPT (1983) dan kriteria kombinasi kesuburan fisika tanah (Sitorus, 1985). Tahap persiapan sampai pengolahan data status kesuburan tanah adalah berbasis SIG. Hasil penelitian menunjukkan bahwa status kesuburan tanah total pada lokasi penelitian yaitu kelas rendah 216,74 ha (14,50%), kelas sedang 899,56 ha (60,21%) sampai kelas tinggi 303,35 ha (20,31%). Arahan perbaikan kesuburan tanah di DAS Wai Ela adalah manajemen pemupukan berimbang, penambahan bahan organik (pupuk kandang, pupuk hijau) pada tahapan pengolahan tanah, manajemen pH tanah yang sesuai dan pengaturan air irigasi yang tepat. Kata kunci: aspek kimia dan fisik, DAS Wai Ela, kesuburan tanah, Negeri Lima

Abstract

Most of the paddy rice farmers have not provided an appropriate response to the innovation of environmentally friendly rice management, because the ability or capacity owned by farmers has not been able to support the production of environmentally friendly and sustainable farming products. The capacity of farmers to manage environmentally friendly paddy rice is closely related to individual behavior towards technological innovations that are applied and disseminated. This study aims to determine the productivity of paddy rice with an environmentally friendly management approach. The research was conducted in Merauke Regency, Papua Province, from July to November 2018 during the gadu planting season (MT II). The design used was a factorial Randomized Block Design (RBD) with 4 child factors, each variety used was Bawor 9, Black Madras, M70, Sertani 8. The results showed that the treatment of four varieties differed on plant height, number of tillers , panicle length, weight 1000 Grains, harvest grain weight, grain dry grain weight, empty grain amount, rice grain amount and heavy stover. Keywords: Management, Paddy rice, Environmental friendly Sebagian besar petani padi sawah belum memberikan respon yang tepat atas inovasi pengelolaan sawah yang ramah lingkungan, karena kemampuan atau kapasitas yang dimiliki petani belum mampu mendukung dalam menghasilkan produk-produk usahatani yang ramah lingkungan dan berkelanjutan. Kapasitas petani dalam mengelola padi sawah ramah lingkungan berhubungan erat dengan perilaku individu terhadap inovasi teknologi yang diterapkan dan didesiminasikan. Penelitian ini bertujuan untuk mengetahui produktivitas padi sawah dengan pendekatan pengelolaan ramah lingkungan.

Abstract

Upland rice-based cropping pattern is a form of multiple cropping including intercropping, sequential planting, and relay planting where upland rice as a base crop can be preceded and/or rotated with other food crops as a secondary crop. The research was aimed to provide recommendations for upland rice-based cropping pattern technology in dryland agroecosystems in Maluku that would be able to increase land productivity > 1.00 (MCI = Multiple Cropping Index > 100%) compared to existing cropping patterns. The study used a Randomized Block Design (RCBD) with four treatments and repeated five times (farmers as replications). Four treatments for upland rice-based planting pattern technology assemblies, namely: 1) Pattern-A (Farmer A Pattern); 2) Pattern-B (Farmer B Planting Pattern B); 3) Pattern C (Farmer Improvement Cropping Pattern); and 4) Pattern D (Introduced Plant Pattern). The results showed that upland rice was planted double (multiple cropping) through intercropping and/or sequential cropping, namely Improved Cropping Patterns (Pattern C = Upland Rice + Corn - Peanuts) and Introducing Cropping Patterns (Pattern D = Upland Rice + Corn/Cassava - Green Beans - Peanuts) can increase land productivity with a double-cropping index 1.35 - 1.80 (IPG = 135% - 180%) compared to upland rice grown in monoculture (Farming Patterns). Multiple cropping (Upland Rice + Corn/Cassava - Green Beans - Peanuts) can be recommended as Upland Rice-Based Planting Technology Package on dry land in Maluku, because it can increase land productivity> 1.00 with an MCI (Multiple Cropping Index) of 180%. Keywords: dry land, performance, upland rice ABSTRAK Pola Tanam berbasis padi gogo merupakan bentuk pola bertanam ganda meliputi tumpangsari, tumpang gilir (runtun) dan tanaman sisipan dimana padi gogo sebagai komoditi pokok (base crop) yang bisa didahului dan atau digilir dengan tanaman pangan lainnya sebagai komoditi ikutan (secondary crop). Tujuan dari penelitian ini adalah untuk mendapatan rekomendasi paket teknologi pola tanam berbasis padi gogo pada agroekosistem lahan kering di Maluku yang mampu meningkatan produktivitas lahan > 1.00 (IPG = Indeks Pertanaman Ganda >100 %) dibandingkan dengan pola tanam petani eksisting. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan empat macam perlakuan dan diulang lima kali (petani sebagai ulangan). Empat perlakukan rakitan teknologi pola tanam berbasis padi gogo, yaitu: 1) Pola-A (Pola Tanam Petani A); 2) Pola-B (Pola Tanam Petani B); 3) Pola C (Pola Tanam Petani Perbaikan); dan 4) Pola D (Pola Tanaman Introduksi). Hasil penelitian menunjukkan bahwa padi gogo ditanam secara ganda (multiple cropping) melalui tumpangsari dan atau tumpanggilir, yaitu Pola Tanam Petani Perbaikan (Pola C = Padi Gogo + Jagung - Kacang Tanah) dan Pola Tanam Introduksi (Pola D = Padi Gogo + Jagung/Ubikayu - Kacang Hijau - Kacang Tanah) dapat meningkatkan produktivitas lahan 1.35 – 1.80 (IPG = 135% - 180%) dibandingkan jika padi gogo ditanam secara monokultur (Pola Tanam Petani). Pola bertanam ganda (Padi Gogo+Jagung/Ubikayu - Kacang Hijau - Kacang Tanah) dapat direkomendasikan sebagai Paket Teknologi Pola Tanam Berbasis Padi Gogo pada lahan kering di Maluku, karena dapat meningkatkan produktivitas lahan >1.00 dengan nilai IPG (Indeks Pertanaman Ganda) 180%.

Abstract

Herbivorous insects and plants have a very complex interaction relationship, where plants play an important role in shaping the behavior and development of herbivorous insects. Nutrients contained in plants in the form of secondary compounds also determine whether or not plants were selected by insects. The objective of the research was to study the preferences of Henosepilachna sparsa herbivorous insects on several cultivated plants. The study was conducted in October 2013 at the Toxicology Laboratory, Department of Plant Protection, Faculty of Agriculture, Bogor Agricultural University. The steps of the experiments were: a) Extracting plant materials such as takokak, eggplant, tomatoes, and broccoli using hexane and methanol solvents; and b) imago H. sparsa preference of plant was takokak plant extract with methanol solvent, takokak plant material with Hexane solvent, tomato plant with Methanol solvent, tomato plant material with Hexane solvent, eggplant plant material with Methanol solvent, eggplant material with Hexane solvent, broccoli with Methanol solvent), broccoli plant material with Hexane solvent was carried out using a three-branched olfactometer (Y form). Imago H. sparsa of plant extract was taken from around the taro plant in Bogor. The results of the study show that the imago H. sparsa insect preference test for extraction of test plants using hexane solvents was better than methanol solvents. Extraction of eggplant plants with hexane solvents has the highest retention value (Rf) of 0.751 cm with the assumption that the higher the Rf value, the more metabolites are detected. Keywords: allelochemics, attractants, broccoli, eggplant, repellent, tomatoes, takokak ABSTRAK Serangga herbivora dan tanaman memiliki hubungan interaksi yang sangat kompleks, dimana tanaman mempunyai peran yang penting dalam membentuk perilaku dan perkembangan serangga herbivora. Nutrisi yang dikandung tanaman berupa senyawa sekunder juga menentukan dipilih atau tidak dipilih suatu tanaman oleh serangga. Penelitian bertujuan untuk mempelajari preferensi serangga herbivora Henosepilachna sparsa pada beberapa tanaman budidaya. Penelitian dilaksanakan pada bulan Oktober 2013 di Laboratorium Toksikologi, Departemen Proteksi Tanaman Fakultas Pertanian, Institut Pertanian Bogor. Tahapan penelitian meliputi: a) Ekstraksi bahan-bahan tanaman seperti takokak, terung, tomat, dan brokoli dengan menggunakan pelarut heksana dan metanol; dan b) Preferensi imago H. Sparsa terhadap ekstrak bahan tanaman takokak dengan pelarut Metanol, bahan tanaman takokak dengan pelarut Heksana, bahan tanaman tomat dengan pelarut Metanol, bahan tanaman tomat dengan pelarut Heksana, bahan tanaman terung dengan pelarut Metanol, bahan tanaman terung dengan pelarut Heksana, bahan tanaman brokoli dengan pelarut Metanol, bahan tanaman brokoli dengan pelarut Heksana dilakukan menggunakan olfaktometer yang bercabang tiga (bentuk Y). Imago H. sparsa diambil dari sekitar pertanaman talas di Bogor. Hasil penelitian menunjukkan bahwa uji preferensi serangga imago H. sparsa terhadap ekstraks tanaman uji menggunakan pelarut heksana lebih baik dari pelarut metanol. Ekstraksi tanaman terung dengan pelarut heksana memiliki nilai retensi tertinggi (Rf) 0,751 cm dengan dugaan bahwa semakin tinggi nilai Rf maka semakin banyak senyawa metabolit yang terdeteksi.
