Abstract

This research aims to determine the survey location and symptoms of F. oxysporum wilt on melon plants, how to take samples of plants with symptoms of F. oxysporum wilt, isolate the F. oxysporum fungus in the laboratory, inoculate F. oxysporum fungal spores onto melon plants, incubation period and percentage disease attacks after inoculation of F. oxysporum fungal spores, melon fruit weight and net pattern of melon fruit. This research was carried out at Greenhouse Lahan Indonesia (LI), Maguwoharjo Village, Depok District, Sleman Regency, Yogyakarta Special Region. The research was conducted from April to June 2023. The research used descriptive and quantitative methods to study, describe, explain and describe the objects studied. The research sample plants were 26 plants, namely 5 plants as controls, 21 plants were inoculated with F. oxysporum fungal spores. Location of survey for Fusarium oxysporum wilt symptoms in the Plataran Greenhouse, Selomartani Village, Kalasan District, Sleman Regency, DI Yogyakarta. The survey results showed that there were melon plants that had symptoms of F. oxysporum wilt. The percentage of melon plants affected is 40% of the total plant population. Sampling of melon plant stems with symptoms of F. oxysporum wilting was taken 20 cm from the soil surface and cut to a length of 10 cm. Take 2 plants that experience symptoms of F. oxysporum wilt. Isolation of F. oxysporum fungus using PDA media in a petri dish. Fungal colonies and macroconidia were found which are characteristic of F. oxysporum fungal spores which are shaped like a crescent moon. Inoculation of fungal spores on melon plant stems can cause healthy plants to become sick. On the 10th day there were 2 or 9% of plants showing symptoms of F. oxysporum wilting. There were differences in the weight and net pattern of melon fruit on control plants compared to test plants.

Abstract

Basal stem rot caused by the fungus Ganoderma boninense is the major threat to oil palm plantations in Indonesia, especially for second generation. Handling oil palm residues during the replanting process greatly determines the fungal attack. This research aims to reveal how handling oil palm trunks affects G. boninense attacks on second generation oil palm plantations. The treatments studied were felled trunk and felled-chipped trunk, each represented by two blocks (five years old of oil palm) with a density of 143 trees/hectare. The results of the study showed that second generation oil palms had a very high prevalence of basal stem rot disease, even though there were differences in the incidence and severity of the disease. Chipping of felled trunk residues can slow the development of the disease. Management of palm residues has a major influence on the onset of this disease in replanted oil palms.

Abstract

Abstract:  The aloe vera plants cultivated by the Sumber Rejeki Women Farmers Group are currently in poor condition, characterized by yellowing leaves. This indicates a significant nutrient deficiency. However, the group members lack the skills to produce organic fertilizer. To address this, community service initiatives are needed to provide training on the production and application of Liquid Organic Fertilizer (LOF) using locally available materials, specifically goat manure and aloe vera leaf scraps. The primary objective of this program is to empower the members with the practical knowledge to create and apply this organic fertilizer to restore the health of their aloe vera crops. employed methods such as socialization, construction of fermentation barrels, hands-on training, evaluation, and mentoring. The training significantly improved participants' understanding, with overall comprehension of liquid organic fertilizer (increasing by 47%, knowledge of production methods rising by 41%, awareness of benefits growing by 29%, and familiarity with materials increasing by 50%. The resulting liquid organic fertilizer had an average composition of 0.56% organic carbon, 0.03% total nitrogen, 0.02% P₂O₅, 0.07% K₂O, and a C/N ratio of 18.86. Aloe vera plants fertilized with this liquid organic fertilizer exhibited greener fronds, a higher number of fronds, longer fronds, and an average frond weight of 300-400 grams.Abstrak: Tanaman lidah buaya milik KWT Sumber Rejeki mengalami penurunan kualitas yang ditandai dengan pelepah berwarna kekuningan. Kondisi ini menunjukkan kurangnya nutrisi, namun para anggota belum memiliki keterampilan untuk memproduksi pupuk secara mandiri. Oleh karena itu perlu dilakukan pelatihan pembuatan Pupuk Organik Cair (POC) dengan memanfaatkan bahan-bahan lokal yang tersedia yaitu kotoran kambing dan sisa-sisa pelepah lidah buaya. Tujuan pengabdian masyarakat ini adalah memberikan pelatihan pembuatan pupuk organik cair berbahan baku kotoran kambing dan sisa-sisa pelepah lidah buaya serta aplikasinya pada tanaman lidah buaya. Metode yang dilakukan meliputi sosialisasi, pembuatan tong fermentasi serta pelatihan dan praktek pembuatan pupuk organik cair serta evaluasi kegiatan dan pendampingan. Tingkat pemahaman peserta pelatihan POC terdapat kenaikan 47%, dengan tingkat pemahanan sangat paham 18% dan cukup paham 82%. Pengetahuan peserta mengenai cara pembuatan POC meningkat sebesar 41%  dengan tingkat pemahanam 9% sangat paham dan 91% cukup paham. Pemahaman mengenai manfaat POC mengalami peningkatan 29% (tadinya  71% menjadi 100% peserta). Pemahaman mengenai bahan-bahan yang digunakan untuk membuat POC meningkat sebesar 50%. POC yang dihasilkan mempunyai rata-rata kadar C-organik 0,56%, kadar N total 0,03%, kadar P2O5 0,02%, kadar K2O 0,07% dan rasio C/N sebesar 18,86. Tanaman lidah buaya yang dipupuk dengan POC akan memiliki warna pelepah yang hijau, jumlah pelepah lebih banyak, pelepahnya lebih panjang dan berat pelepah sekitar 300-400 gram
