Abstract

The Silverleaf whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae), is a destructive insect pest of important greenhouse and field crops. Several studies have shown the effectiveness of Beauveria bassiana in controlling Silverleaf whitefly.. However, a major challenge lies in the rapid evaporation of water in greenhouse crop models. Therefore, this study aimed to evaluate the effectiveness of B. bassiana against the whitefly and test its compatibility with various vegetable oils as carrier media. This research at the Agrotechnology Laboratory, Faculty of Agriculture, University of Jember, used pure isolates of B. bassiana for mass production until conidia reached 2.5 x 107 per gram. We employed a Completely Randomized Design (CRD) with factors of vegetable oil (Corn Oil, Vegetable Oil, Soybean Oil) and concentration (5%, 10%, 15%) using Ultra Low Volume (ULV) formulations. The results revealed that the addition of vegetable oils enhanced the effectiveness of B. bassiana in controlling Silverleaf whitefly, with corn oil having the most significant impact due to its high carbohydrate content that supported B. bassiana viability. Additionally, the concentration of B. bassiana formulation also influenced the rate of whitefly mortality (mycocity), with a 15% concentration yielding the best results. Whitefly nymphs infected with B. bassiana exhibited slowed activity and reduced appetite. Adding vegetable oil facilitated the formation of a protective biofilm around conidia, shielding them from UV radiation, increasing conidia viability, and supporting field application. The infection process by B. bassiana required 6 days to achieve 100% mortality. This research suggests that B. bassiana can be an effective alternative for controlling Silverleaf whiteflies, especially when used with plant-based oils as a carrier medium. This approach may help reduce reliance on chemical pesticides and address issues related to Silverleaf whitefly resistance to insecticides.

Abstract

Oyster mushroom (Pleurotus ostreatus) is a popular mushroom in Indonesia, with several factors affecting its yield, including seed quality, cultivation methods, and environmental conditions. The choice of planting media is crucial, as it must provide essential nutrients. Common media include straw and coffee husks, with the addition of liquid organic fertilizer (LOF) enhancing productivity. Maja fruit is particularly beneficial due to its NPK content, supporting mushroom growth. This research, conducted from February to May 2024 in Klungkung Village, Jember Regency, employed a completely randomized design (CRD) with three replications. The study tested media compositions—100% sawdust (M1), 75% sawdust and 25% straw (M2), and 75% sawdust and 25% coffee husk (M3)—alongside varying LOF concentrations: no LOF (P0), 75 ml/liter (P1), 150 ml/liter (P2), and 225 ml/liter (P3). Results indicated that the interaction between LOF concentration and media composition significantly affected the total number and weight of fruiting bodies. The best combination was P1M2 (75 ml LOF/liter with 75% sawdust + 25% straw). Media composition significantly influenced the number and weight of fruiting bodies, with M3 (75% sawdust + 25% coffee skin) recommended as the optimal choice. LOF concentration notably impacted total fruit body weight, while other parameters showed no significant differences.

Abstract

Desa Wonoasri memiliki potensi dalam pengembangan program kampung Iklim (ProKlim) yang salah satunya pada aspek pemanfaatan pekarangan masyarakat. Oleh karena itu kegiatan pengabdian ini bertujuan untuk mengembangkan Desa ProKlim melalui pemanfaatan pekarangan berkelanjutan di Desa binaan Wonoasri, Kecamatan Tempurejo, Kabupaten Jember. Metode pendekatan yang digunakan adalah pendekatan personal dan kelompok melalui sosialisasi dan studi banding, Focus Group Discussion (FGD), dan pendampingan serta demonstrasi. Tolok ukur keberhasilan pengembangan Proklim adalah respon positif Masyarakat dan perangkat desa terhadap keseluruhan kegiatan yang akan dilakukan. Hasil dari kegiatan pengabdian ini adalah respon positif dari masyarakat terhadap ProKlim yang cukup tinggi dengan keterlibatan 35 masyarakat yang mewakili berbagai kalangan (anak muda, ibu-ibu PKK, bapak-bapak, LMDHK, perangkat desa) dan diskusi interaktif selama kegiatan. Selain itu tiga kolam ikan lele model terpal berkerangka besi diameter 3m dengan masing-masing 1000 bibit ikan lele telah direalisasikan. Demikian juga halnya dengan realisasi 6 rangka besi vertikultur tanaman sayuran yang meliputi tomat, terong, dan pakcoi. Aktivitas diversifikasi produk mangga juga sudah dilaksanakan yaitu memberikan teori dan praktik dalam diversifikasi olahan buah mangga menjadi sirup, puding, kue bolu, dan manisan. Kesimpulan dari kegiatan pengabdian ini yaitu pengembangan ProKlim di Desa Wonoasri berhasil dilakukan berdasarkan respon positif masyarakat, realisasi kolam ikan dan vertikultur, dan diversifikasi produk buah mangga. Selanjutnya program ini juga mendapat dukungan sepenuhnya dari Kepala Desa Wonoasri yang akan melanjutkan program Desa ProKlim.

Abstract

Soybeans is one of important food sources in Indonesia mainly as protein resources. The needs of soybeans which increasing and lower number of cultivation land causes soybeans import. Soybeans productivity improvement could be done by agroforestry system. Mindi and sentang are a fast growing species which famously cultivated at this time. One of benefit gained from agroforestry system is providing sources of organic material. Planting combination between mindi and sentang with soybeans could give organic material such as from mindi leaves and sentang leaves. This research aimed to examine the response of soybeans growth to the additional of leaves. The experimental design used was Complete Random Design (CRD) with single factor and seven treatments (control, dry whole, dry chopped, dry powder, wet whole, wet chopped, and wet powder. This research shows that the addition of sentang leaves does not impact to the diameter and height growth. The additional of mindi leaves give not significantly different to the growth of soybeans diameter, total dry mass, and total wet mass. The additional of sentang leaves give effect to the growth of number of leave, total wet mass, total dry mass and total pud mass. The additional of mindi leaves give significant impact to the height, number of leaves, and pot mass. The treatment give best impact to total pud mas was sentang dry leave chopped and mindi dry leave whole.Key words: Agroforestry, Azadirachta excelsa, Glycine max, Melia azedarach

Abstract

Saat ini kendala utama dalam budidaya kakao yaitu terkait penyakit busuk buah kakao yang disebabkan oleh jamur patogen Phytophthora palmivora masih belum terselesaikan. Hal ini disebabkan kondisi perkebunan kakao yang lembab menyebabkan patogen lebih cepat berkembang dan meluas dalam waktu singkat. Hal tersebut ditambah dengan seresah kulit buah kakao yang menjadi sumber inoculum penyebaran patogen. Sejauh ini petani melakukan pengendalian dengan bantuan fungisida kimia sintetik yang mahal dan tidak ramah lingkungan. Alternatif pengendalian yang murah dan ramah lingkungan yaitu dengan memanfaatkan jamur saprofit isolat lokal dari kulit buah kakao yang dapat berperan sebagai agens hayati. Penelitian dilakukan pengujian interaksi dan dominasi sesama jamur saprofit. Tujuannya adalah untuk mengetahui kemampuan berkompetisi dan hubungan antara jamur saprofit satu dengan jamur saprofit lainnya. Berdasarkan hasil penelitian bahwa jamur saprofit diduga memiliki hubungan interaksi kompetisi, mikoparasit dan antibiosis. Sedangkan hasil dominasi terendah hingga tertinggi yaitu Trichoderma sp. 3, Aspergillus sp., Trichoderma sp. 2, Trichoderma sp. 1, Rhizopus sp., Fusidium sp., Penicillium sp., dan Candida sp. Jamur saprofit dari seresah kulit buah kakao memiliki potensi dalam mengendalikan Phytophthora palmivora.

Abstract

Lembaga Masyarakat Desa Hutan Konservasi (LMDHK) Wonomulyo merupakan kelompok masyarakat yang fokus pada kegiatan konservasi di Taman Nasional Meru Betiri (TNMB). Dalam upaya peningkatan skill dan kompetensi kegiatan konservasi tersebut, maka tim pengabdian Universitas Jember melakukan kegiatan pengabdian kepada LMDHK Wonomulyo dengan tema penguatan “Citizen Science” dalam menginisiasi pembentukan ekowisata “birdwatching”. Kegiatan ini dilakukan pada bulan Juli-September 2023 dengan beberapa kegiatan yang meliputi sosialisasi kegiatan, peningkatan pemahaman, dan implementasi lapang. Berdasarkan kegiatan pengabdian yang telah dilakukan, pengurus LMDHK telah mendapatkan skill pengamatan burung berdasarkan morfologi, identifikasi menggunakan buku panduan, dan rekapitulasi data. Keragaman jenis burung yang ditemukan di zona rehabilitasi Resort Wonoasri TNMB memiliki potensi sebagai pengembangan paket wisata “birdwatching”.
