Abstract

Bawang merah (Allium cepa var ascalonium L.) merupakan tanaman hortikultura yang banyak dibudidayakan oleh masyarakat Indonesia. Pemanfaatan lahan suboptimal sebagai lahan budidaya bawang merah bertujuan untuk meningkatkan area luasan panen dan produktivitas bawang merah yang mengalami fluktuasi hingga penurunan pada tahun 2022. Alternatif lahan suboptimal untuk budidaya bawang merah adalah pemanfaatan lahan kering dengan kondisi lengas lapang sebagai faktor pembatas utama. Upaya yang dapat dilakukan guna meningkatkan produktivitas lahan kering yaitu dengan pemanfaatan varietas unggul tahan kekeringan. Penelitian ini bertujuan untuk mengetahui pengaruh cekaman lengas tanah, jenis varietas, dan hubungan antara cekaman lengas tanah dengan jenis varietas terhadap pertumbuhan dan hasil bawang merah. Percobaan dilakukan dengan metode Rancangan Acak Lengkap (RAL) dua faktor yaitu kadar lengas tanah dan jenis varietas. Kadar lengas tanah terdiri dari 100% (L1); 75% (L2); and 50% (L3), sedangkan varietas bawang merah terdiri dari varietas Sanren (V1); varietas Lokananta (V2); dan varietas Maserati (V3). Varietas Maserati menunjukkan tinggi tanaman tertinggi yaitu 39,2 cm dengan jumlah daun yaitu 5,9 helai. Kadar lengas tanah 75% kapasitas lapang pada varietas Maserati memberikan jumlah daun terbanyak yaitu 8,33 helai. Produktivitas varietas Sanren sebesar 0,189 t ha-1, varietas Lokananta sebesar 0,2 t ha-1, dan varietas Maserati sebesar 0,222 t ha-1.

Abstract

Kedelai (Glycine max L.) merupakan komoditas strategis penghasil protein nabati, namun produktivitasnya sering terhambat oleh defisiensi nitrogen. Penelitian ini bertujuan mengevaluasi pengaruh pemberian Rhizobium sp. terhadap pertumbuhan dan produktivitas kedelai varietas Dering. Percobaan menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan tiga perlakuan dosis Rhizobium (0 mg, 5 mg, dan 10 mg per tanaman) dan lima ulangan. Hasil menunjukkan bahwa dosis 5 mg meningkatkan tinggi tanaman secara signifikan (81,28 cm), sedangkan dosis 10 mg meningkatkan jumlah daun (23,8 helai), cabang (2,8 cabang), dan polong (38 polong per tanaman). Analisis statistik (ANOVA pada taraf signifikansi 5%) mengonfirmasi perbedaan nyata antar perlakuan. Simbiosis Rhizobium-kedelai efektif mendukung fiksasi nitrogen dan mengurangi ketergantungan pada pupuk anorganik. Dosis 10 mg direkomendasikan untuk produktivitas optimal.

Abstract

Kemiri Village, Panti District, Jember Regency is one of the rice-producing villages but faces the problem of scarcity of subsidized fertilizers and ineffective management of agricultural waste. This needs to be overcome with simple but effective handling. This community service activity aims to empower farmers through the production of Local Microorganisms (MOL) and Plant Growth Promoting Rhizobacteria (PGPR) to increase rice productivity while supporting the potential of livestock in the village. The target partner in this activity is the Sidodadi farmer group consisting of 30 farmers. The implementation method includes training in making MOL and PGPR, applying PGPR to rice plants, and making silage as animal feed. The results of the activity show that the activities carried out related to the use of PGPR can help increase rice growth, improve yields, and reduce dependence on chemical fertilizers. In addition, making silage successfully processes green fodder into quality feed that supports food security for livestock in the village. In the future, this activity is expected to strengthen the sustainability of agricultural and livestock practices in Kemiri Village and improve the economy of farmers.

Abstract

Declining soil fertility caused by the continuous use of chemical fertilizers has encouraged the development of sustainable and environmentally friendly nutrient management strategies. Compost tea, a liquid extract derived from mature compost, has gained attention due to its potential to supply readily available nutrients and beneficial microorganisms. This study aimed to evaluate the compost tea production process and assess the effects of aerated compost tea (ACT) and non-aerated compost tea (NACT) at different application concentrations on the early growth of maize (Zea mays L.). The experiment was conducted under controlled conditions in November 2025 using maize as the test plant. Compost tea was prepared by extracting mature compost in water at a ratio of 1:5, with aeration applied for ACT and without aeration for NACT over a three-day fermentation period. Treatments consisted of ACT and NACT applied at concentrations of 30 ml and 60 ml, along with a control. Plant growth parameters, including plant height and root length, were observed during the early growth phase (2–7 days after planting). The results showed that compost tea application significantly affected maize growth during the early growth stage (P < 0.05). Aerated compost tea generally produced better growth responses than non-aerated compost tea, particularly at lower concentrations. The ACT treatment at 30 ml resulted in the highest plant height and root length, while higher concentrations, especially NACT at 60 ml, tended to suppress plant growth. These findings indicate that compost tea primarily functions as an early growth stimulant and that excessive application may reduce its effectiveness. In conclusion, aerated compost tea at low concentrations is more effective in promoting early maize growth than non-aerated compost tea. Proper optimization of compost tea concentration and application strategy is essential to maximize its benefits within sustainable agricultural systems.

Abstract

Abstrak: Permasalahan utama peternak sapi di Desa Mayangan adalah ketergantungan pada jerami padi segar bernutrisi rendah (protein 3,8%) dan biaya pakan konsentrat tinggi. Program ini bertujuan meningkatkan kapasitas peternak memproduksi pakan fermentasi, mengurangi biaya pakan, dan mendorong kemandirian teknologi. Keterampilan yang ditingkatkan mencakup hardskill (pengoperasian mesin Straw Baller, pengepresan, pengemasan kedap udara, fermentasi anaerob) dan softskill (kerja sama, problem solving, pengelolaan sumber daya pakan). Kegiatan berupa penyuluhan, pelatihan, dan praktik pembuatan pakan fermentasi diikuti 27 peternak Kelompok Tani Muneng Makmur 2. Evaluasi melalui observasi dan angket 10 pertanyaan menilai pengetahuan, keterampilan teknis, dan kesiapan adopsi teknologi. Indikator keberhasilan meliputi penguasaan teknik ≥80%, penurunan volume jerami ≥40%, dan peningkatan kepadatan penyimpanan ≥1,5 kali. Hasil menunjukkan keterampilan meningkat 85%, volume jerami berkurang 41–59%, kepadatan penyimpanan naik 1,7–2,4 kali, serta potensi peningkatan palatabilitas dan pertumbuhan bobot harian sapi.Abstract: The main challenge for cattle farmers in Mayangan Village is their reliance on low-nutrient fresh rice straw (3.8% crude protein) and the high cost of commercial concentrate feed. This program aimed to enhance farmers’ capacity in producing fermented feed, reduce feed costs, and promote technological self-reliance. Skills targeted included hardskills (operation of the Straw Baller machine, pressing, airtight packaging, anaerobic fermentation) and softskills (teamwork, problem solving, and feed resource management). Activities comprised lectures, training, and hands-on practice in fermented feed production involving 27 farmers from the Muneng Makmur 2 Farmers Group. Evaluation was conducted through field observation and a 10-question questionnaire assessing knowledge, technical skills, and readiness for technology adoption. Success indicators included ≥80% mastery of techniques, ≥40% reduction in straw volume, and ≥1.5-fold increase in storage density. Results showed an 85% skill improvement, 41–59% volume reduction, 1.7–2.4× storage density increase, and potential improvement in feed palatability and daily weight gain.
