The distribution of benefits among supply chain actors is complex and full of challenges because various factors, including uncertainty, influence it. This study aims to solve the problem of profit distribution to produce a fair profit distribution among supply chain actors by incorporating elements of uncertainty, risk, and value-added. The model of fair profit distribution is made using the cooperative game theory approach with fuzzy Shapley values, which incorporates the elements of uncertainty in profit, risk, and added value. The fair profit distribution between supply chain actors is validated in the sago agro-industry supply chain in the Meranti Islands Regency. The risks of each supply chain actor were obtained using the fuzzy analytical hierarchy process technique, with risk values of 0.52, 0.23, 0.2, and 0.29 for farmers, traders, wet starch agro-industries, and dry starch agro-industries, respectively. While the value-added ratio of each supply chain actor is 12%, 35.92%, 13.9%, and 15.1%, respectively, as obtained by the Hayami method. The model validation results show that the fair profit distribution to farmers is 17.77%, to traders it is 29.69%, to the wet starch agro-industry it is 9.91%, and to the dry starch agro-industry it is 42.63% of the total supply chain profits. This result is more proportional than the current profit distribution, which is respectively 10.03%, 15.29%, 1.7%, and 72.98%. These results are considered fairer and more proportional because they take into account the uncertainty of the benefits, risks, and added value of each actor in the sago agro-industry supply chain. Keywords: fair profit distribution, fuzzy Shapley value, sago agro-industry, supply chain, uncertainty

Streptomyces genera plays an important role in lignocellulose degradation. Many research found that Streptomyces have cellulolytic and ligninolytic enzymes that are sufficient to degrade lignocellulosic materials. However, a minimum lignocellulosic material condition that can efficiently be degraded by sp. has Streptomyces not been fully understood. In this research, three pretreatment conditions (physical, alkaline-hydrothermal, and hydrogen-peroxide chemical treatments) of sugarcane bagasse were used as lignocellulosic material to be further degraded by Streptomyces sp. S2. Lignocellulose component measurement concluded that raw (physically treated only) bagasse was not efficiently degraded byÂ Streptomyces sp S2. Hydrogen-peroxide was effective in reducing both syringic and guaiacyl lignin. Meanwhile, alkaline-hydrothermal pretreatment was very effective in lowering syringic lignin. This study suggests that hydrogen-peroxide pretreatment can be used in any type of lignocellulosic material, which can be further degraded by Streptomyces sp. S2. On the other hand, alkaline hydrothermal pretreatment is best suited to degrade lignocellulosic material with a high percentage of syringic lignin. Key words: Alkaline-hydrothermal treatment, Hydrogen peroxide treatment, lignocellulose,Â Streptomyces sp.Â S2, sugarcane bagasse

Sago palm frond is the upper part of the sago palm trunk and is not utilized during sago harvesting. Sago palm frond contains low non-cellulose components; thus, it is the potential to be used as the production of cellulose hydrolysate. The result contains cello-oligosaccharides and cellobiose which can be utilized as a prebiotic that is beneficial to the human digestion system. The cellulolytic enzyme is used as a catalyst to produce intermediate hydrolysate. therefore, it requires a certain hydrolysis process. This research investigated the characteristics of sago palm frond and the extraction of its cellulose, and its application as a substrate for cellulose hydrolysis. The results showed that the upper half frond contains a higher crude fiber (35% wet basis) and cellulose components (37% wet basis) than the bottom one. Up to 72 hours the hydrolysis produced cello-oligosaccharides and cellobiose with a degree of polymerization of 7.9 and a dextrose equivalent of 12.6.

Corn has the potential to be converted into flour, but its hard endosperm causies it to have a coarse particle size, and consequently, corn flour has high crude fiber, low protein, and high moisture. To overcome these problems, the milling of corn grain can be done by steeping it in water. The steeping process causes spontaneous growth of microbes, such as lactid acid bacteria and cellulolytic bacteria. The use of lactid acid bacteria and cellulolytic bacteria in the steeping process can soften the horny endosperm, which can enable corn grits to be ground into fine flours and which can improve the chemical properties of flour passed through an 80-mesh sieve. This study aimed to obtain isolates of indigenous lactid acid bacteria and cellulolytic bacteria from the corn steeping process, and to apply them as a starter in the steeping process of corn grits to improve the fine flour yield, and the chemical properties of flour passed through an 80-mesh sieve. Isolate E2213BAL was the lactid acid bacteria selected as the highest optical density at the logarithmic phase, while isolate B2121SLT was the cellulolytic bacteria with the highest enzyme activity (4.67 mU/ml). The results showed that the use of bacteria starter and fermentation time can decrease pH, increase total acid in the fermentation liquid, decrease the crude fiber, maintain protein, and decrease the moisture of corn flour passed through an 80-mesh sieve.

Isolation of Cellulolytic Bacteria and Characterization of the Enzyme. Four of cellulolitic bacteria isolates had been characterized. The determination of cellulase activity was conducted at the highest production time, using crude enzymes with the modification of Miller methods (1959) on pure cellulose substrates such as CMC (Carboxymethyl cellulose), Avicel and Filter paper Whatman No. 1 as well as agriculture waste such as rice straw, corn cob and banana peel. Cellulase from C4-4, C5-1, C5-3 and C11-1 showed optimum activity at pH 5, 70°C, pH 3.5, 90°C, pH 5, 80°C and pH 8, 70°C, respectively. Avicel is a appropriate substrate for C4-4 cellulase whereas CMC for the other three. C11-1 cellulase has the highest cellulase enzyme activity on rice straw substrate whereas C4-4 cellulase on banana peel substrates. C5-1 and C5-3 cellulase have relatively low cellulase activities in degrading substrates of agriculture waste. However, isolates of C5-1 and C5-3 have high cellulase activities on banana peel substrates.

Background: Lactic Acid Bacteria (LAB) starter is an instant LAB culture that has been prepared to initiate lactic acid production in the fermentation process. The manufacture of BAL starter requires alternative media as a substitute for MRS media which costs a lot when used for industrial production. To protect cells, an encapsulant matrix is needed which functions to provide insulation for bacterial cells against the drying process which can damage cells and a good media is needed and is capable of being an encapsulation matrix in the manufacture of dry LAB starter. Lactobacillus plantarum NHC6 bacteria is a lactic acid bacteria that has the potential to be developed. Method: making encapsulation matrix using rice bran. The bran media consisted of 10% (w/v) rice bran added with 5% (w/v) glucose and 1% (w/v) ammonium sulfate. As much as 10% (w/v) of L. plantarum NHC6 culture which was in the late log phase was inoculated in bran media. The liquid starter was then incubated again for 14 hours at 37°C. After that, the drying process was carried out using a spray dryer at an inlet temperature of 170°C. Result: The number of live cells in the bran starter decreased after the spray drying process. Starter storage at 28°C and 4°C has a significantly different effect. Conclusion: Rice bran matrix is capable of being an encapsulating agent and is able to protect L. plantarum NHC6 cells from high temperatures during the spray drying method in the manufacture of dry starter.

Controlled/slow-release fertilizers (CSRF) continue to be developed because of the need to increase agricultural productivity and reduce the economic, social, and environmental impacts of conventional fertilizers leaching into nature. Additionally, the use of biodegradable polymers as CSRF materials continues to be a priority in CSRF development. Therefore, this review synthesizes the current research on lignin- and polysaccharide-based CSRFs and emphasize their compatibility and performance in agricultural applications. Lignin, an abundant and renewable biopolymer, was evaluated for its effectiveness as a slow-release agent in CSRF. Studies have demonstrated the potential of lignin to improve nutrient release profiles and environmental sustainability when used alone or in combination with other polymers. Polysaccharides, which are known for their biocompatibility and biodegradability, have also been explored. The incorporation of lignin into polysaccharide-based CSRFs has been highlighted, particularly in starch, cellulose, chitosan, and sodium alginate matrices. These composites offer improved mechanical properties, controlled nutrient release, and enhanced soil water retention. The challenges and future directions regarding lignin- and polysaccharide-based CSRF are also reviewed. These findings underscore the importance of developing sustainable fertilizer technologies to meet future food demands while mitigating environmental impacts. Keywords: controlled/slow-rele ase fertilizer, composite matrix, lignin, polysaccharide, urea
