    Meskipun terkenal sebagai negara agraris, kebutuhan pokok masyarakat Indonesia masih tergantung pada negara asing. Produksi pertanian Indonesia tidak mengalami peningkatan, bahkan cenderung menurun. Salah satu penyebabnya adalah kurangnya pengetahuan petani dan tidak adanya komunikasi atas kebijakan yang telah dibuat pemerintah kepada penggerak pertanian. Penelitian ini bertujuan untuk merancang aplikasi media sosial bidang pertanian di Indonesia yang disebut dengan ASMI (Agriculture Social Media Indonesia). Perancangan prototype menggunakan metode Mobile Development Life Cycle (MDLC) dengan tahapan identifikasi, perancangan, pembangunan, prototype, pengujian,dan perawatan. Hasil penelitian menunjukkan prototype ASMI dapat digunakan untuk melengkapi kebutuhan informasi dan komunikasi bidang pertanian. Prototype ASMI dapat digunakan oleh masyarakat, petani, pemerintah, pemerhati pertanian, peneliti, dosen, dan pakar sebagai media komunikasi bidang pertanian

    The objective of this research was to study the functional response of M. sexmaculatus. The hypothesis of this study was that age of predator and the numbers of prey will effect predation rate. To test this hypothesis, a set of prey (first and fourth instar and adult R. maidis) was separately placed together with first and fourth instar larval and adult female of M. sexmaculatus at different densities. The length of the exposure of the hosts were respectively 13, 14 and 2 hours for 1st instar larval predator, 4th instar larval predator and adult predators. In addition a combination of 1st and 4th instar nymph of R. maidis were exposed to adult M. sexmaculatus for 24 hours. The result of this study showed that the ability to predation of young and adult M. exmaculatus was type II, indicating that M. sexmaculatus can be categorized as effective biological control agent. Adults of M. sexmaculatus are better predators than the larval stages. Based on non linear regression analysis, the maximum numbers of preys consumed by adult females of M. sexmaculatus was 300 individuals of various stages of R. maidis per 24 hours

    In nature many different types of prey encountered, but information concerning the ability of predators to preys on the prey is still less The goals of this research was to knew functional response i.e. the relationship between ability of individual M. sexmaculatus to eat prey (R. maidis) on differential population density. The hypothesis of The study was the more availability of prey (R. maidis) and the older of predator stages M. sexmaculatus), then predation ability would growing up. The research method is to place directly larvae (first instar and fourth instar) and adult female M. sexmaculatus predator was on its prey, R. maidis, in a variety of population densities with first instar nymphs, the fourth and adult The result of this study shown that the ability to predation of young and adult of M. sexmaculatus was Type II to R. maidis, so it was categorized as effective biological control agent. Ability to predation of adults stages of M. semaculatus is better than young stages. Based on analysis of non linear regression, to the maximum predation of female adults of M. sexmaculatus was 300 various stage of R. maidis per 24 hours. . KEY WORDS: Functional response, M. sexmaculatus and R. Maidis

    The study aims to determine the presence of pests and natural enemies on soybean plants and to study the effect of insecticides on the diversity. Methods for observation of insects was done by using different type of traps i.e. yellow pan trap, pitfall trap, light trap, sweeping net and direct observation (visual). The presence of pests and natural enemies of soybean plants on plots without insecticide was lower than on the plots that was treated with insecticide. Composition of the population of pests found in soybean plots that were not treated with insecticide were dominated by Aphis sp. followed by Phaedonia inclusa, Riptortus linearis, Nezara viridula and Ophiomyia phaseoli. Composition of the population of natural enemies (predators) found in soybean cropps that were not treated with insecticide was family Coccinellidae followed by Syrphidae, Chrysopidae, Mantidae and Oxyopidae. The highest composition of natural enemies (parasites) found in treated and untreated soybean plots were family Braconidae then followed by family Ichneumonidae

    ABSTRAKCabai merah (Capsicum annuum L) salah satu hasil pertanian yang penting dan banyak dibudidayakan di Indonesia. Produktivitas cabai di Indonesia saat ini masih tergolong rendah. Selain itu, permasalahan yang dihadapi adalah mutu cabai kurang baik. Faktor-faktor yang menyebabkan rendahnya produktivitas cabai Indonesia antara lain penggunaan benih yang kurang bermutu, teknik budidaya yang belum efisien dan penanaman kultivar cabai yang tidak tahan terhadap hama serta penyakit. Rendahnya produksi pada tanaman cabai menunjukkan bahwa kurangnya pupuk atau zat pengatur tumbuh pada tanaman cabai. Pemberian bakteri dapat meningkatkan pertumbuhan dan produksi tanaman. Bakteri yang dapat memacu pertumbuhan dan produksi tanaman memiliki peran sebagai Plant Growth Promoting Rhizobacteria (PGPR), ialah kelompok mikroorganisme tanah.yang menguntungkan. PGPR merupakan golongan bakteri yang hidup dan berkembang dengan baik pada tanah yang kaya akan bahan organik. Tujuan dari penelitian ini adalah untuk mengetahui dari masing-masing bentuk formula yang berbahan aktif agensia hayati Pseudomonad fluorescent isolat 122 dalam meningkatkan pertumbuhan dan produksi tanaman cabai dilapang dan untuk mengetahui dosis dari masing-masing bentuk formula yang efektif dalam meningkatkan pertumbuhan dan produksi tanaman cabai dilapang. Penelitian ini disusun berdasarkan rancangan acak kelompok (RAK) dengan dua factor yakni formula dan dosis. terdapat 9 kombinasi perlakuan yang diulang sebanyak 3 kali dan masing-masing ulangan terdiri dari 10 sampel. Pada penelitian yang telah dilakukan dapat diambil kesimpulan bahwa perlakuan formula serbuk dosis 10 g jika diaplikasikan di skala lapang paling efektif dalam pertumbuhan dan produksi tanaman cabai. Faktor serbuk dan dosis pada fase vegetatif tidak menunjukkan adanya interaksi, tetapi pada fase generatif menunjukkan adanya interaksi pada kedua faktor.Kata kunci : Pseudomonad fluorescent, PGPR dan Tanaman Cabai MerahABSTRACTRed chili peppers (Capsicum annuum L) one of the agricultural products that are important and widely cultivated in Indonesia. Productivity chili in Indonesia is still relatively low. In addition, the problems faced are less good quality chili. Factors that lead to low productivity of Indonesian chili, among others, the use of poor seed quality, yet efficient cultivation techniques and planting chilli cultivars that are not resistant to pests and diseases. The low production in pepper showed that the lack of fertilizers or growth regulators in pepper. Giving bacteria can promote the growth and crop production. Bacteria that can spur the growth and production of crops have a role as PlantGrowth Promoting Rhizobacteria (PGPR), is a group tanah.yang beneficial microorganisms. PGPR is a group of bacteria that live and thrive in soil that is rich in organic matter. The purpose of this study was to find out from each masingbentuk formulas that contain active biological agents isolates of fluorescent pseudomonads 122 growth and production of pepper plants dilapang and to determine the dose of each form of formula effective in enhancing the growth and production of pepper plants dilapang. This study is based on randomized complete block design (RAK) with two factors namely formula and dosage. There are nine combination treatment was repeated 3 times and each replicate consisted of 10 samples. In the research that has been done can be concluded that the treatment dose of 10 g of the powder formulation when applied in the most effective field scale in the growth and production of pepper plants.
