Prototype Media Sosial Pertanian di Indonesia untuk Perangkat Bergerak Berbasis Android

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

Kemampuan Pemangsaan Menochilus Sexmaculatus F. (Coleoptera: Coccinellidae) Terhadap Rhopalosiphum Maidis Fitch (Homoptera: Aphididae)

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

Keanekaragaman Serangga Hama Dan Musuh Alami Pada Lahan Pertanaman Kedelai Di Kecamatan Balong-Ponorogo

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
