Abstract

Rice (Oryza sativa L.) is a vital food crop in Indonesia's economy. It is grown in both irrigated and rainfed rice fields. However, rainfed rice fields have low nutrient content, requiring significant fertilization. To reduce reliance on chemical fertilizers, agricultural technological advancements are necessary, including the use of endophytic bacteria. The research aimed to assess the impact of an endophytic bacterial consortium on rice rooting and yield under various nitrogen and phosphorus doses in suboptimal rainfed land. The study was conducted in Demangan Village, Sambi District, Boyolali Regency, from March 2023 to June 2023, using a factorial Complete Group Design. The research consisted of two factors , each repeated three times. The first factor was nitrogen fertilizer, with four levels: no urea, 100 kg/ha urea, 200 kg/ha urea, and 300 kg/ha urea. The second factor iwas phosphorus fertilizer, with four levels,: no phosphorus, 80 kg/ha phosphorus, 160 kg/ha phosphorus, and 240 kg/ha phosphorus. The observed parameters included fresh root weight, dry root weight, root volume, root length, root diameter, root surface area, weight of 1000 grains, grain weight per plant, and grain weight per plot. The results revealed no significant effects of nitrogen, doses, phosphorus doses, or interactions between nitrogen and phosphorus doses on any of the observed parameters. In conclusion, the application of an endophytic bacterial consortium can reduce the need for nitrogen and phosphorus fertilizers in rainfed rice fields.

Abstract

Penelitian ini bertujuan untuk mengoptimalkan teknik perbanyakan bibit pisang Cavendish (Musa spp.) secara in vitro melalui kombinasi mutasi induksi menggunakan radiasi sinar gamma dan modifikasi media dengan penambahan pupuk daun. Penelitian dilakukan dengan rancangan acak lengkap (RAL) menggunakan dua faktor: dosis radiasi sinar gamma (0 Gy, 10 Gy, 20 Gy, 30 Gy, dan 40 Gy) dan jenis media (MS, MS + Pupuk Daun, dan Pupuk Daun). Hasil penelitian menunjukkan bahwa jumlah tunas yang dihasilkan berkisar antara 1 hingga 2 tunas per eksplan, tanpa perbedaan nyata antara berbagai dosis radiasi dan jenis media. Dosis radiasi 20 Gy terbukti optimal untuk pertumbuhan tunas, menghasilkan tinggi tunas tertinggi (8,15 cm), sementara dosis 40 Gy menghambat pertumbuhan akibat kerusakan DNA. Media MS dan MS + Pupuk Daun lebih mendukung pembentukan akar dibandingkan media Pupuk Daun saja. Dalam proses aklimatisasi, Media MS menunjukkan persentase keberhasilan yang sangat tinggi (100%) pada hampir semua perlakuan, termasuk paparan radiasi hingga 40 Gy, sedangkan media Pupuk Daun kurang efektif, terutama pada paparan radiasi tinggi. Secara keseluruhan, Media MS direkomendasikan sebagai media terbaik untuk mendukung pertumbuhan dan aklimatisasi bibit pisang Cavendish, sementara dosis radiasi 20 Gy terbukti optimal untuk mendorong pertumbuhan tunas.

Abstract

Bacteria play a role in processing agricultural waste into compost. Rice and corn straw waste has potential as organic fertilizer. This research aims to compare the effectiveness of decomposer bacteria in the composting process. The research was carried out in Bowan, Klaten, February-June 2023, using a completely randomized factorial design consisting of 8 treatments and 4 replications. The first factor is the type of bacteria consisting of no bacteria, cellulotic+rhizomonas, cellulotic+BRS, rhizomonas+subtilis, subtilis, while the second factor is the type of composting media, namely straw and corn. Observations include water hold capacity, time, weight and compost water content. The results of the research show that the type of bacteria influences the water hold capacity, time and weight of the compost. In the composting process, corn waste is more effective than straw. The interaction of the type of bacteria and composting media influences the water holding capacity, time and weight of the compost. In conclusion, subtilis bacteria play an important role in accelerating composting, increasing efficiency through the correct interaction of bacteria and waste. Corn waste is superior to straw in producing high quality compost.
