Abstract

Abstract. Hidayati YA, Nurachma S, Badruzzaman DZ, Marlina ET, Harlia E. 2021. Utilization of sheep dung and rice straw with indigenous microbial agent to optimize vermicompost production and quality. Biodiversitas 22: 5445-5451. Sheep dung is a useful by product that can be potentially processed into more useful products with minimal pollution. Vermicomposting is a waste processing method that produces Solid Organic Fertilizer and worm biomass as the raw materials for drugs and cosmetics. This research aimed to utilize the role of indigenous fungi and bacteria to determine the influence of C/N ratio from sheep dung and rice straw mixture on vermicompost quality (N, P, K, Ca, Mg). This experimental research was conducted in a Completely Randomized Design with three treatments (T1: C/N ratio of 25; T2: C/N ratio 30; T3: C/N ratio 35) and six replicates for each treatment. Data so obtained were analyzed with ANOVA and Duncan's Multiple Range Test. The results showed that C/N ratio had a noticeable influence on vermicompost quality. C/N ratio 30 produced the highest vermicompost quality (N: 1.11 ± 023381%; P: 0.56 ± 0.010328 %; K: 0.51 ± 0.021369 %; Ca: 0.33 ± 0.0248 %; Mg: 0.14 ± 0.0228%).

The Effect of Sheep Dung on the Growth of Odot Grass (Pennisetum purpureum cv. Mott)

“…Another thing that is thought not to affect the treatment of sheep dung in each treatment is that sheep dung has a hard texture, so it will increase the time it takes for decomposition by microbes in the soil. The process of composting sheep dung is carried out by microbes that use organic materials as an energy source (Hidayati et al, 2021). Metabolic processes greatly influence plant height in the plant body itself.…”

Pengaruh Nisbah C/N dalam Vermicomposting Campuran Ekskreta Ayam Petelur dan Serasah Dedaunan terhadap Perubahan Suhu, Jumlah Total Bakteri, dan Koliform

“…Wilayah kampus Unpad memiliki lahan terbuka hijau dengan tanaman peneduh yang cukup dominan sehingga menghasilkan serasah dedaunan yang melimpah, serasah dedaunan yang dihasilkan ± 1,2 ton/ hari dan belum diolah secara baik melainkan serasah dedaunan tersebut berakhir di al., 2020;Hidayati et al, 2021). Nisbah C/N yang optimal akan mempengaruhi vermicomposting, vermicomposting meningkatkan keragaman dan aktivitas mikroba, serta menghasilkan vermikompos yang kaya akan unsur hara yang dapat meningkatkan pertumbuhan tanaman (Shrihari, 2015).…”
