Background and Aim: Irradiated chitosan can be used as a matrix for slow-release urea (SRU) production. This study aimed to (1) determine the optimal formulation of irradiated chitosan matrix for controlling nitrogen release and (2) evaluate the characteristics of SRU in vitro fermentation based on irradiated chitosan as a feed supplement. Materials and Methods: In the first phase of the investigation, four chitosan-based SRU formulations with varying amounts of acrylamide (3 and 5 g) and gamma irradiation (5 and 10 kGy) were evaluated. Scanning electron microscopy, Fourier transform mid-infrared spectroscopy, and ammonia release characteristics were used to observe morphological, functional group, and ammonia release characteristics. In the second phase of research, the most effective SRU formulation was utilized as a supplement to ruminant rations based on rice straw, sorghum straw, and alfalfa. Gas production, rumen fermentation characteristics, and methane gas production were observed in vitro. Results: On the basis of surface image analysis, the four SRU formulas generate a similar appearance. Compared with untreated urea, the SRU3 formula reduced the percentage of ammonia emission by 12.85%–27.64% after 24 h of incubation (p = 0.05), as determined by the first phase study. SRU3 became the basis for the second testing phase. The addition of SRU3 did not affect the optimal gas production in vitro. SRU3 treatment produced less gas than Optigen® treatment (p = 0.05). With regard to rumen fermentation and digestibility, Optigen® yielded better results than SRU3 (p = 0.05). However, the treatment with SRU3 resulted in reduced methane production compared to that in the control (p = 0.05). Conclusion: Irradiated chitosan as an SRU matrix may control the release of ammonia in the rumen medium. The SRU3 formulation is the most effective. The addition of SRU to rice straw-based rations reduces methane production without affecting in vitro digestibility. Keywords: fermentation characteristics, irradiated chitosan, ruminant, slow-release urea.

“…Proses fementasi pakan di dalam rumen dipengaruhi oleh nilai pH rumen. Pada kondisi pH rumen normal akan mendorong interaksi optimal antara bakteri selulotik, fungi, dan protozoa (Wahyono et al, 2014). Oleh karena itu, pengujian nilai pH juga penting untuk menilai keberhasilan fermentasi pakan di dalam rumen.…”

ABSTRAK Penelitian ini bertujuan untuk mengkaji nilai kecernaan bahan kering (KcBK), nilai kecernaan bahan organik (KcBO), dan nilai pH rumen yang diuji secara in vitro dalam fermentasi anaerob kulit singkong dengan biostarter Mikroorganisme Lokal (MOL) dari media pertumbuhan yang berbeda. Penelitian ini menggunakan rancangan acak lengkap dengan 4 perlakuan dan 5 ulangan meliputi P0 (1 kg kulit singkong + 1% EM4 + 3% molases), P1 (1 kg kulit singkong + 1% MOL1 + 3% molases), P2 (1 kg kulit singkong + 1% MOL2 + 3% molases), P3 (1 kg kulit singkong + 1% MOL3 + 3% molases). Data dianalisis menggunakan analylis of variance (ANOVA). Fermentasi anaerob kulit singkong dengan penambahan berbagai biostarter MOL memberikan hasil yang berbeda tidak nyata (P>0,05) terhadap nilai KcBK, nilai KcBO dan nilai pH cairan rumen secara in vitro. Nilai rerata pada P0, P1, P2, dan P3 masing-masing untuk KcBK adalah 60,38%; 59,43%; 54,94%; 54,41%; untuk KcBO adalah 64,03%; 63,23%; 58,78%; 58,69%; dan untuk pH cairan rumen adalah 6,71; 6,62; 6,58; 6,63. Hasil penelitian menyimpulkan bahwa penggunakan berbagai biostarter MOL dapat digunakan untuk menggantikan biostarter komersil EM4 dalam proses fermentasi kulit singkong. Kata kunci: fermentasi kulit singkong, MOL ABSTRACT The study aims to identify the Digestibility of Dry Matter (KcBK), Organic Matter Digestibility (KcBO) values, and rumen pH values tested in vitro in anaerobic fermentation of cassava peels with Indigenous Microorganisms (MOL) biostarter from different growth media. This study used a completely randomized design with 4 treatments and 5 replications including P0 (1 kg of cassava peel + 1% EM4 + 3% molasses), P1 (1 kg of cassava peel + 1% IMO1 + 3% molasses), P2 (1 kg of cassava peel + 1% IMO2 + 3% molasses), P3 (1 kg of cassava peel + 1% IMO3 + 3% molasses). The data were analyzed using analysis of variance (ANOVA). Anaerobic fermentation of cassava peels with the addition of various IMO biostarters gave not significantly different results (P>0.05) on KcBK values, KcBO values, and rumen fluid pH values in vitro. The average scores at P0, P1, P2, and P3 for KcBK were 60.38%; 59.43%; 54.94%; 54.41%; for KcBO were 64.03%; 63.23%; 58.78%; 58.69%; and for rumen fluid pH were 6.71; 6.62; 6.58; 6,63. The results of the study concluded that the use of various IMO biostarters can be used to replace the commercial EM4 biostarter in the cassava peel fermentation process.

Sorghum is a multifunctional crop as a source of food, feed, and alternative energy. Plant breeding using the radiation mutation technique was applied to improve the characteristics of sorghum according to its purpose. This study evaluated the agronomic and fiber characteristics of selected sorghum mutant lines. Eight sorghum mutant lines were observed in this study (GHP-2, GHP-3, GHP-4, GHP-5, GHP-7, G-5, P-341, and P36.M10). Pahat and Bioguma sorghum varieties were used as control. Compared to eight selected mutant lines, Bioguma variety was the tallest plant. Except for P-341, all selected mutant sorghum lines produced lower plant biomass than Bioguma. The highest sugar content was produced by G-5 and P-36.M10. There are no significant differences in seed production per panicle. The lowest fiber fractions in the leaf and stem were produced by GHP-3 and G-5 mutant lines, respectively. Based on our findings, the P-341 sorghum mutant line can be used as forage sorghum because it produces high biomass and relatively low fiber content. The G-5 mutant line can be projected as an alternative energy source due to its high stem sugar content. Keywords: agronomy, fiber, mutant, sorghum
