Abstract

EFFECTS OF CHITOSAN COATING ON THE PHYSICAL, MECHANICAL AND ANTIMICROBIAL PROPERTIES OF FOOD PACKAGING PAPER. The coating process on food packaging paper is carried out to improve the food safety and health aspect from dangerous substance migration from food packaging into food. Chitosan has attracted interest in packaging, especially in food packaging as edible films and coatings. A paper from oil palm empty fruit bunches (OPEFB) pulp was coated with chitosan using different pulp weight (1, 1.5, 2 g) and chitosan content (0.25, 0.50, 0.75, 1 g) as parameters. The effect of chitosan as coating material on physical, mechanical, and antimicrobial properties was studied. The results showed that the density and grammage values of the paper increased after coating due to the increasing of chitosan content. The mechanical properties of the coated paper, such as tensile strength, tensile modulus and elongation, improved in line with the increase of chitosan content and pulp weight. The addition of chitosan on paper imparts antimicrobial properties against Gram-positive bacteria (Staphylococcus aureus) and Gram- negative bacteria (Escherichia coli).

Abstract

The common food container product was made from plastic such as polypropylene, polystyrene, etc which has slowed to degrade hence affected to the environmental pollution and health disorder. Therefore, environmentally friendly food container composite is developed from sustainable resources such as sorghum bagasse and citric acid. The effects of sorghum species, sorghum particles and citric acid content on the composite properties were investigated. Local species of sorghum was used as raw material such as Super 2 in the manufacturing of food packaging.  The size and moisture content of the particles were passthrough on 40 mesh and 10%, respectively. The content of the particle was variated such as 10, 15, and 20% wt. Furthermore, citric acid was used as a binder with difference content such as 10, 20, and 30% wt.  Those raw materials were mixed with tapioca starch, polyvinyl alcohol (PVA), and glutaraldehyde. The mixing material was hot pressed at 180 ℃ for 15 minutes. The composite dimension was 12 cm x 10 cm x 3 mm. The physical and mechanical properties of the composite were carried out. Considering the properties of the composite, sorghum bagasse and citric acid are suitable as raw material of food container composite.

Abstract

Industrial residues that are not optimally utilized are removed by burning, landfilling, or dumping, which can threaten the environment and health. In fact, part of this agro-industrial waste still has content that has the potential to become raw material for value-added other industries. Dates by-product as residue of the fiber-rich fruit industry have the potential to be a source of nanocellulose. This study aims to obtain nanofibril cellulose (CNF) isolates from dates by-product via citric acid hydrolysis, and investigate the effect of acid concentration on the unknown dates by-product CNF isolate characteristics. Pretreatment such as delignification and bleaching is needed to obtain cellulose isolate with high purity. Furthermore, acid hydrolysis, centrifugation, and sonication are performed to obtain CNF. CNF isolates are characterized by the analysis of particle size distribution, morphology, and crystallinity. Analysis of functional groups and lignocellulose content test confirm that lignin and hemicellulose are degraded during isolation. The particle size distribution measurement shows that the greater the acid concentration, the smaller the CNF size and the better the size uniformity. The morphology of the CNF obtained is net-like fibers. The degree of crystallinity shown decreases with increasing acid concentration. This study revealed that different citric acid concentrations can result in different characteristics of CNF isolates.

Abstract

An analysis of consumer preferences to find out the characteristics of handicraft paper from betel nut fiber desired is necessary for this innovation. This study aimed to determine the attributes of handicraft paper that are most necessary for consumers. This study was conducted by using Conjoint method. Fifty respondents completed structured questionnaires in some cities in Indonesia. The attribute mix used in this study was physical and organoleptic. The physical attribute mix was tensile strength, grammage, thickness, and stiffness while the organoleptic was color, fiber appearance, and surface texture. There were 16 combinations of stimuli formed with simplification using orthogonal arrays. The result shows consumers like tensile strength of 20-<30 kN/m2, grammage of ≥500 g/m2, thickness of 1,6-3 mm, stiffness of ≥15 mN.m, dark brown color, the appearance of fiber was visible, and had rough surface texture. The results of the correlation analysis showed that there was a strong correlation between the results of preference stimuli and actual responses. The handicraft paper produced had the same characteristics as the consumer preference, except the tensile strength with thevalue ranged from 10-<20 kN/m2. The results also showed that fiber appearance had the highest relative importance value to be prioritized.

Abstract

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

Abstract

Salt as a source of important minerals is much needed by society and industry. In the salt-making process, salt must go through a drying phase. Salt drying at the Badan Riset Nasional (BRIN)’s workshop that uses wood pellet as the fuel is considered not optimal because of waste in waiting and processing time. Other alternative fuels are needed to maximize the salt production process, one of which is using used lubricating oil. Utilizing used lubricating oil as fuel for the salt drying process requires the conversion of burner or stove. This research aims to design a stove fueled by used lubricant oil for drying industrial salt. French method is used to design the stove. The stove that has been built iwas compared with wood pellet stove in terms of waiting time to reach the desired salt drying temperature, fuel operational costs, and capacity of the salt produced. The ST-44 steel oil stove with a diameter of 17 cm and a height of 13 cm could reach the drying temperature 15 minutes faster than a wood pellet stove without the need of supervising the feeding process. Daily operational costs for fuel consumption using used lubricating oil were also more economical with 25% more dry salt produced than using a wood pellet stove.
