Abstract

Kemampuan Indonesia dalam memenuhi kebutuhan beras nasional sangat penting. Akan tetapi, usaha pemenuhan kebutuhan beras ini tidak selamanya berjalan dengan lancar karena terganggunya produktivitas padi. Salah satu penyebab turunnya produktivitas padi di Indonesia karena adanya serangan serangga hama. Beberapa kendala yang menyebabkan gagalnya petani dalam mengendalikan serangga hama karena petani masih belum melakukan identifikasi serangga hama dan gejala serangan dengan baik. Penelitian yang dilaksanakan akhir tahun 2012 ini yang berlokasi di Lahan Persawahan Padi Dataran Tinggi Desa Sukawening, Kecamatan Ciwidey, Kabupaten Bandung, Jawa Barat bertujuan meng inventarisasi dan mendapatkan nilai keragaman jenis serangga hama pada tanaman padi. Penangkapan serangga hama yang dilakukan dengan menggunakan perangkap kuning, perangkap jaring dan perangkap cahaya. Hasil penangkapan serangga diidentifikasi di laboratorium. Indeks keragaman serangga dianalisis dengan menggunakan perhitungan Shannon- Weinner. Serangga hama yang dominan diperoleh pada fase vegetative yaitu Scirpophaga incertulas, Thaia oryzivora, dan Orselia oryzae. Serangga hama minor diperoleh yaitu Dicladispa armigera, Leptispa pygmaea, dan Melanitis ledaismene. Serangga hama yang dominan diperoleh pada fase generative yaitu Leptocorisa acuta, Scirpophaga incertulas, dan Thaiaoryzivora. Serangga hama minor diperoleh yaitu Nilaparvata lugens, Sogatella furcifera, dan Cofana spectra. Indeks keragaman serangga hama yang diperoleh pada ketiga lahan percobaan ada diantara sedang hingga tinggi.Pada fase vegetatif indeks keragaman tertinggi sebesar 4,74 pada pengamatan ke 6 dan terendah pada pengamatan ke 1 sebesar 2,22. Pada fase generatif indeks keragaman tertinggi pada pengamatan ke 9 sebesar 4,86 dan terendah pada pengamatan ke 12 sebesar 1,37.   Kata kunci :indeks keragaman, serangga hama, padi, Kabupaten Bandung.

Abstract

Ciplukan merupakan tanaman dari daerah subtropis yang mulai dibudidayakan di Indonesia karena memiliki banyak manfaat di bidang kesehatan. Kendala dalam budidaya ciplukan yaitu adanya gangguan serangga hama. Predator dan parasitoid merupakan komponen biotik penting dalam pengendalian serangga hama ciplukan secara alami di lapangan, oleh karena itu informasi keberadaan dan keragaman predator dan parasitoid pada pertanaman ciplukan perlu diketahui. Penelitian ini dilakukan untuk memelajari keragaman arthropoda predator dan parasitoid serangga hama pada lahan ciplukan (Physalis peruviana L.) di Desa Kadakajaya, Kecamatan Tanjungsari, Kabupaten Sumedang, Jawa Barat. Pengambilan sampel dilakukan menggunakan yellow sticky trap dan pitfall trap sebanyak enam kali dalam kurun waktu dua bulan. Saat pengambilan sampel, tanaman ciplukan berada pada fase generatif, yaitu sudah berbuah dan sudah beberapa kali dipanen. Pengambilan sampel dilakukan pada lahan berukuran 30 x 10 meter pada ketinggian 1013 meter di atas permukaan laut. Arthropoda yang tertangkap selama sampling terdiri dari 13 ordo dan 70 famili yang dapat berperan sebagai predator, parasitoid, dan netral, dengan jumlah individu sebanyak 7131. Berdasarkan data tersebut, diperoleh Indeks Keragaman yang termasuk kategori sedang, Indeks Kemerataan tinggi (>0,6) dan tidak ada arthropoda yang mendominasi dengan hasil Indeks Dominansi <1, yang berarti tidak ada populasi arthropoda dalam satu famili yang mendominasi di lokasi survey. Hasil perhitungan indeks keragaman, kemerataan, dan dominansi ini menunjukkan kondisi lingkungan yang stabil. Beberapa predator dan parasitoid yang banyak ditemukan berasal dari ordo Diptera, Hymenoptera, Coleoptera, dan Hemiptera. Selain arhtropoda yang berperan sebagai predator dan parasitoid, ditemukan pula arthropoda yang berperan sebagai polinator, dekomposer, dan makanan alternatif bagi predator, yaitu dari ordo Entomobryomorpha, Poduromorpha, Coleoptera, Diptera, dan Isopoda.

Abstract

Effectiveness of Nano Chitosan and Nano Silica to Suppress the Growth of Fusarium oxysporum, the Cause of Twisting Disease on Shallot Shallot twisting disease caused by Fusarium oxysporum f.sp. cepae is one of the major diseases on shallot. Alternative fungicides such as nano-sized chitosan and silica can be applied as environmentally friendly control methods. The objectives of this study were to evaluate the ability of a single or mixture of nano chitosan and nano silica to inhibit the in vitro growth of F. oxysporum and reduce the development of twisting disease on shallot plants, as well as to determine their effective concentrations. The in vitro test was arranged in a completely randomized design, while the in vivo test was arranged in a randomized complete block design with 10 treatments and three replications. The treatments were application of single nano chitosan at 50 ppm, 100 ppm, 200 ppm, single nano silica at 50 ppm, 100 ppm, 200 ppm, mixture of nano chitosan 50 ppm + nano silica 50 ppm, mixture of nano chitosan 100 ppm + nano silica 100 ppm, control, and 200 ppm of fungicide mancozeb 80%. The results showed that all treatments, compared to control, were able to suppress the in vitro growth of F. oxysporum colonies, as well as the disease development on shallot plants. Application of single nano chitosan at 100 ppm, and the mixture of nano chitosan at 100 ppm + nano silica 100 ppm caused the highest inhibition of the colony growth of F. oxysporum, which were 85.2% and 81.3% respectively, comparable to the application of mankozeb (83.5%). The mixture of nano chitosan at 100 ppm + nano silica 100 ppm was effective in suppressing the development of shallot twisting disease on shallot plants. The suppression was 56.3%, comparable to mankozeb which was 50.5%.

Abstract

Taro is an important agricultural commodity with considerable prospects for international market competition. However, its cultivation faces several challenges, particularly pathogen infections that can lead to substantial yield losses. Conducting a disease inventory in taro plants is essential for effective disease management and serves as a preliminary step in developing resistant taro varieties. This study aimed to document diseases affecting 38 accessions of taro plants. The research was conducted from August to October 2021 at the Ciparanje Jatinangor Experimental Field and the Phytopathology Laboratory within the Department of Plant Pests and Diseases at the Faculty of Agriculture, Universitas Padjadjaran, located in Sumedang Regency. The methodology employed both qualitative and quantitative descriptive approaches. Data collection involved observing the incidence and severity of diseases, as well as identifying the pathogens responsible for the diseases. A total of 292 taro plants were examined during this study. The diseases identified included brown leaf spot (Cladosporium colocasiae), shot hole (Phoma sp.), orange leaf spot (Neojohnstonia colocasiae), white leaf spot (putative Pseudocercospora colocasiae), and leaf blight (Phytophthora colocasiae), along with other symptoms suspected to be caused by root pathogens and viruses.The most prevalent disease observed at the experimental site was brown spot disease, while leaf blight was identified as the most damaging. The incidence of leaf spot and leaf blight reached 100% across nearly all accessions of taro planted at the research site, with the highest severity of disease recorded at 49.65%.

Abstract

The present community service was aimed to socialize techniques for preparing citrus planting materials in the ecotourism activist community at Pajagan Village, Cisitu District, Sumedang Regency. The socialization was attended by 30 people who were a combination of academics, representatives of Pajagan village-owned enterprise (Bumdes), and ecotourism activists whose daily professions are farmers in the Cipicung farmer group, Pajagan. To produce citrus planting material, grafting is a prerequisite vegetative propagation technique for obtaining standardized tangerine planting material. Grafted seedlings are more recommended than seed originated seedling, because of flower quickly, resistant to damping off, pests and diseases. Grafting is performed to connect the upper stem/scion of a tangerine cv. Siam Madu with superior fruit characteristics and the lower stem/rootstock of a sour rough lemon (Citrus jambhiri). It is hoped that this outreach activity can grow public interest and knowledge in producing planting material independently in the future.
