Abstract

Managing end-of-life tyres (ELTs) has become an urgent global issue because tyres are difficult to decompose naturally and take more than 50 years to break down. In the Jabodetabek (Jakarta, Bogor, Depok, Tangerang, Bekasi) area, ELT generation is estimated at 2.5–3 million units annually, with the most significant contributions from Karawang (1,000 units per month) and Bogor (820 units per month). Bias-ply used tires, which contain up to 70% rubber, have significant potential for recycling into raw materials for new tires through reclaimed rubber technology, aligning with the principles of a circular economy. This study aims to map the supply chain ecosystem of ELTs, identify key stakeholders, and optimise material flow to support the development of the rubber industry from reclaimed materials. The study employs a qualitative descriptive method. The number of research locations was determined using the Solvin method with an error rate of 25%. Observations were performed at 15 specific tire shops, two truck tire shops, three fleets, and three used tire collectors in the Jabodetabek and West Java areas. The findings indicate that the total estimated number of ELTs collected in Jabodetabek from tire stores, truck tires, fleets, and collectors reaches 2,860 monthly units. The main challenges in ELT management include limited storage facilities, low awareness of the economic value of waste, and a predominantly conventional management system. The study also reveals that only 20% of ELTs are utilised optimally, highlighting a significant untapped potential.  Keywords: used tires, reclaimed rubber, supply chain, circular economy

Abstract

Carrageenan, a natural sulfated polysaccharide extracted from red seaweed, has gained significant attention in the development of drug delivery systems, particularly as a capsule-forming material. With its biodegradable, biocompatible, and gel-forming properties, carrageenan offers great potential as a plant-based alternative to animal-derived gelatin. This review evaluates the potential of carrageenan, especially iota-carrageenan, in the production of soft capsules as a gelatin substitute, and compares the characteristics of carrageenan-based hard and soft capsules. Soft capsules are generally formulated with iota-carrageenan and plasticizers such as glycerol to achieve optimal flexibility, while hard capsules utilize kappa-carrageenan due to its stronger gel texture. Structural modifications, including depolymerization and polymer blending, have been reported to improve viscosity, elasticity, and disintegration time of carrageenan capsules. Nevertheless, limitations remain, such as high viscosity and slower disintegration compared to gelatin-based capsules. Therefore, formulation optimization and advanced extraction techniques are essential to enhance carrageenan capsule performance. Future research should emphasize cost-effective and high-purity extraction methods, engineered depolymerization processes, and the modification of kappa-carrageenan to exhibit iota-like flexibility. These strategies are expected to advance the feasibility of tropical seaweed-derived carrageenan as a sustainable and halal-compliant material for pharmaceutical capsule applications.

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

Nonionic surfactants have been used extensively in various industrial applications such as cleaning, personal care, crop protection, paint and coating, textile finishing, emulsion stabilization, food and leather processing. In this study, we have studied the adsorption of three nonionic surfactants of alkyl polyglycoside, namely commercial APG from Cognis and APG produced from glucose as well as APG synthesized from sago starch, at fluidfluid interfaces. The variation of surface and interfacial tension with the concentration of surfactant in the bulk was studied, and the data were fitted using a surface equation of state derived from the Langmuir isotherm. The agreement between ?(c) data and Langmuir isotherm model was very good.Keywords: adsorption, air/water interface, interfacial tension, surface tension

Abstract

Today's modern supply chain represents a complex and real-time, organization, resource, activity, information, and data source that is involved in the distribution of products and services ranging from upstream to downstream of the supply chain. In the past 4.0 supply chain technology was not just a linear business function, but as the center of the main process of ecosystems that are in a blind spot chained by value. With information as a foundation in the decision-making process so that information can create integrated and efficiently coordinated supply chains. So that it can show continuity from planning to production, inventory, quality, and price control in each chain. An inefficient distribution that results in mistrust among stakeholders, because it has an impact on the decline and loss of value chain in quality and quantity. Integrity problems from the data collected were found in this study. These findings include the identification of various stakeholders, including farmers, importers to customers, and regulators, as well as their needs, which will be described through the use case, and BPMN. The results obtained are that the main actors (stakeholders) of the system are divided into farmers, importers, processing factories, headquarters, hauling services, and markets (customers) in the distribution of product information flow systems. Suggests tracking and tracing based on real-time data flow of product information coming from each actor in the sugar supply chain that is equipped with an accurate data distribution information support system.

Abstract

Streptomyces 234P-16 and SKK1-8 are xylanase-producing bacteria. Corncob xylan were extracted using acidified method. Crude enzymes (produced by centrifuging the culture) were used to hydrolyze xylan from 2 varieties of corncob. Crude extract activity was measured by using DNS (Dinitrosalisilic Acid) method. Xylanase from strain 234P-16 has the highest activity if cultivated in 1% Hawaii xylan, whereas strain SKK1-8 on 1.5% Bisma xylan. SKK1-8 xylanase can hydrolize corncob xylan (1% Hawaii or 1.5% Bisma xylan) within 4 hours and produce xylooligosacharide with polymerization degree of 4.76 and 6.37, respectively. Key words: Xylanase, Xylooligosacharide, Streptomyces.

Abstract

The use of cellulose degrading enzyme (cellulases) for hydrolysis of lignocellulosic material is a part of bioethanol production process.  In this experiment,  delignified corncob,  its cellulose fraction and alpha cellulose were used as substrates to produce fermentable sugar by using three local isolates of celluloytic bacteria (C5-1, C4-4, C11-1 and Cmix ; mixed cultures of three isolates), and Saccharomyces cereviseae to produce ethanol. The results showed that all isolates of cellulolytic bacteria can grow on cellulose fraction better than on  delignified corncob, and alpha cellulose.  The highest hydrolytic activity produced from cellulose fraction was by isolate C4-4, which liberated 3.50 g/l of total sugar.  Ethanol can be produced by mixed culture of bacteria and yeast, but because of competitive growth, the fermentation only produced 0.39-0.47 g/l of ethanol. Keywords:  Celluloses, delignified corncob

Abstract

The objective of this study was to determine the effect of nanopropolis on DMBA-induced mammary tumors in rats. After the first tumor appearance, twenty-eight rats were divided into seven groups. Groups 1, 2, and 3 served as recipients of nanopropolis treatments at dosages of 8, 32, and 56 μg/mL, respectively. Group 4 received propolis at 233 μg/mL, Group 5 served as the treatment control, Group 6 received DMBA only, and Group 7 served as the normal control. The effects of nanopropolis at 32 μg/mL and propolis at 233 μg/mL were similar in reducing tumor size, healing wounds caused by the tumor, and eliminating cancer cells. Furthermore, the study suggested a relationship between particle size of the absorbent material and its effectiveness. Overall, nanopropolis was very effective in treating mammary gland tumors and breast cancer even at small concentrations.
