Abstract

Lalat buah merupakan hama yang banyak menimbulkan kerusakan secara kualitatif dan kuantitatif dengan tingkat kerusakan yang mencapai 100%, bahkan serangga ini mampu menentukan arah kebijakan ekspor maupun impor komoditi hortikultura. Lalat buah merupakan spesies hama yang penyebarannya sangat luas, bukan hanya di daerah tropis, serangga ini juga banyak menyerang komoditi pertanian di daerah sub tropis. Sekarang ini lalat buah merupakan hama yang menjadi perhatian dunia di dalam kegiatan ekspor impor buah-buahan yang dilakukan oleh suatu negara. Oleh karena itu, penelitian ini dilakukan untuk mengidentifikasi spesies lalat buah yang tersebar di Pulau Timor, Provinsi Nusa Tenggara Timur. Penelitian ini dilakukan dengan metode survey untuk mendapatkan informasi mengenai spesies lalat buah, jumlah, dan lokasi ditemukannya spesies lalat buah di Pulau Timor. Pengambilan spesimen dilakukan di lokasi pertanian di Kabupaten Kupang, Kabupaten Timor Tengah Selatan, Kabupaten Timor Tengah Utara, Kabupaten Belu dan Kabupaten Malaka untuk memperoleh spesimen yang dikumpulkan dengan menggunakan perangkap berferomon Metyl eugenoal. Pengambilan spesimen lalat buah dilakukan dengan interval waktu dua minggu sekali selama dua bulan untuk mengetahui spesies lalat buah di lokasi tersebut beserta jumlah setiap spesiesnya. Hasil penelitian menunjukkan bahwa terdapat enam spesies lalat buah di Pulau Timor, yaitu: Bactrocera albistrigata, Bactrocera carambolae, Bactrocera dorsalis, Bactrocera umbrosa, Zeugodacus caudata dan Zeugodacus Cucurbitae.

Abstract

This study aimed to detect the presence of key insect pests on corn in Muruona Village, Ile Ape Sub District, Lembata District in East Nusa Tenggara. This research was conducted from November 2020 to January 2021 on farmer's land in the region. This study used a survey method with direct observation techniques on corn plants, and sampling was carried out using sweep nets and sticky traps. The data collected included types of key insect pests, symptoms of damage, population, and intensity of damage to corn by important insect pests. The results showed three key insect pests on corn plantation in the study area: Locusta migratoria, Ostrinia furnacalis, and Helicoverpa armigera. This key pests were detected in corn from the early vegetative to the generative period. The symptoms of damage on corn caused by Locusta migratoria, Ostrinia furnacalis, and Helicoverpa armigera occurred six days after planting (DAP), 28 DAP, and 56 DAP, respectively. Symptoms of damage to corn plants caused by Locusta migratoria are tears in the leaves resembling serrations on the edges of the leaves, both young and old. Symptoms of damage to corn plants caused by Ostrinia furnacalis are grinding holes on the stems so that the stems so that the stem become damaged and then break. Grinding marks on the cobs and dirt and grinding powder characterize symptoms of damage to corn plants caused by Helicoverpa armigera. Populations of the key insect pests Locusta migratoria, Ostrinia furnacalis, and Helicoverpa armigera were very small, with 4, 3 and 1 insect, respectively. Moreover, for the highest intensity of damage to corn plants was caused by Ostrinia furnacalis, but it was categorized as light damage intensity because it was > 0 % ≤ 25%.

Abstract

This research was carried out in Golo Bore Village, Ndoso District, West Manggarai Regency and took place from June to July 2023. The aim of this research was to determine the population of golden snails in baits and traps and the types of golden snails found in each treatment. This research method uses an experimental method with direct experiments in the field. This experiment used two treatments and five replications consisting of taro leaf bait (UDT) and water channel traps in the form of trenches (JSA). Observations were made at the age of the plants 21 days after planting. 28 days after planting and 35 days after planting. The research results in the bait treatment using taro leaves averaged 12 individuals and in the water channel trap treatment in the form of ditches 16.4 individuals. From this research, the gold snails found in the taro leaf bait (UDT) and water channel trap (JSA) treatments were the Pomacea canaliculata type with two different shell variations, namely striped and plain patterns.

Abstract

Produktivitas sayuran di Desa Baumata Kabupaten Kupang relatif rendah akibat rendahnya kesuburan tanah. Upaya peningkatan kesuburan tanah melalui aplikasi pupuk anorganik terkendala oleh efisiensi pemupukan anorganik yang rendah dan seringnya terjadi kelangkaan pupuk di pasaran. Menyikapi kondisi tersebut, aplikasi pupuk organik seperti bokashi plus dan eco-enzym dapat menjadi alternatif untuk memenuhi kebutuhan pupuk di tingkat petani. Untuk itu, petani perlu dibekali dengan pengetahuan dan keterampilan tentang pembuatan dan aplikasi bokashi plus dan eco-enzym. Program Pengabdian pada Masyarakat (PPM) ini digagas oleh kelompok dosen Program Studi Agroteknologi, Fakultas Pertanian, Universitas Nusa Cendana, dengan tujuan: (1) meningkatkan kemandirian mitra dalam memenuhi kebutuhan pupuk dengan memanfaatkan limbah organik; dan (2) meningkatkan keterampilan mitra dalam mengolah bahan organik menjadi bokashi plus dan eco-enzym. Sasaran program PPM ini adalah 10 anggota kelompok tani Manekan di Desa Baumata, Kecamatan Taebenu, Kabupaten Kupang. Metode pendekatan yang digunakan dalam program ini adalah transfer informasi dan alih teknologi, melalui: (1) kegiatan pelatihan pengolahan bahan organik menjadi bokashi plus dan eco-enzym dan; (2) demplot aplikasi bokashi plus dan eco-enzym pada budidaya sayuran. Pelaksanaan Program PPM ini berjalan sesuai target yang ditetapkan dengan tingkat partisipasi anggota kelompok mitra sebesar 100%. Setelah mengikuti program PPM ini, seluruh anggota kelompok mitra mampu membuat bokashi plus dan eco-enzym secara mandiri dan berminat untuk menerapkannya pada usaha tani sayuran yang digelutinya saat ini.

Abstract

Entomopathogen fungi are fungi that become pathogens in insects. This fungus lives, grows, and develops by taking nutrients from the host it is infected with so that the host is disrupted in its metabolism and will then die. This research aims to identify entomopathogen fungi from horticultural plants in Boentuka Village, Batu Putih District, South Central Timor. This research has been carried out from July to October 2022. Sampling of dead insects or infected with entomopathogenic fungi and soil was carried out in Boentuka Village while isolation and identification of entomopathogen fungi were carried out in the Microbiology laboratory, Faculty of Agriculture, Universitas Nusa Cendana. This research uses a purposive sampling method by taking samples based on observations of insects infected with entomopathogen fungi, which are then stored in sample bottles. In addition, soil samples from the site of the entomopathogen fungi attack were also taken and taken to the laboratory, with Tenebrio molitor larvae being used as bait to catch the entomopathogen fungi. The fungi that grew on the larvae and samples of the insects was then isolated and identified. The parameters of observation are the characteristics of isolates that grow macroscopically and microscopicly. The results of the research obtained four isolates of entomopathogen fungi Aspergillus flavus, Aspergillus niger, Beauvaria bassiana, and Fusarium sp. In the future, this isolate will be tested for its ability as a biological agent for pest control in vitro and in vivo.
