Abstract

Biohydrogel has gathered great interest in the pharmaceuticals field. This natural polymers were biodegradable, non-toxic, biocompatible, and its specific ability to response environment change can be considered for the controlled released matric of bioactive compound. In this study, the biohydrogel was synthesized by graft-copolymerization of acrylic acid onto carboxymethyl starch (CMS) and chitosan. The objective of this research was to determine the effect of CMS-chitosan ratio on the biohydrogel characteristic. The acrylic acid was grafted on to the backbone (3:1) using cerric ammonium nitrate as the inisiator.A standarded curcumin was applied to test the binding potency of matrix. A higher CMS ratio in the polymer mixture (4:1) revealed the highest swelling power (16.9 w/w) and percentage of curcumin absorption (17.34%). All samples have pH-responsive swelling properties, with the swelling trend was observed in the order of distilled water >HCl solution > phosphate buffer solution. FTIR spectra and SEM micrographs has confirmed the graft-copolymerization of PAA/CMSCs biohydrogel by describing the appearance of peak around 1600 cm-1and the morphology of granular structure, respectively. The graft-copolymerization of acrylic acid onto the two anionic natural polymer by cerric ammonium nitrate as the initiator has resulted a pH-dependent swelling biohydrogel, and it has the ability to deliver curcumin in stomach-targeted system.

Abstract

Introducing unmodified organically clay/Na-montmorillonite (Na-MMT) was applied into plasticized poly(lactic acid) PLA to produce film composites by direct casting. Film composite structure, the crystallinity degree and form, and thermal properties were carried out using X-ray diffraction and differential scanning calorimetry. The effect of Na- MMT to the tortuous path and the crystallinity degree in the plasticized film composites were calculated in oxygen barrier properties. Chromatogram film composites resulted in an intercalated structure that showed peak diffraction angle shift at about 0.2o. Then, a peak diffraction pattern was indicated in α-form crystal structure. Plasticized PLA has a crystallinity degree at 34%, and the addition of Na-MMT increased to 52%. Glass transition temperature improved from 53 °C to 57 °C, and melting temperature remained stable at 167 °C. Filling Na-MMT into plasticized PLA caused to enhance a tortuous path about 28% and improved the oxygen permeability to 80%. As a result, the addition of Na- MMT of 3% into plasticized PLA during film composite preparation using the mixing method resulted in balancing properties related to the crystallinity degree, thermal properties, and oxygen barrier properties.

Abstract

The complex supply chain system for the sugar agroindustry supply chain involves many actors, resulting in the asymmetry of information data. It still leads to a lack of data transparency. In the past, data traceability could not be made efficient at every stage, so the record data transaction was not real-time, less accurate, and inefficient coordination between actors. Blockchain is one of the technologies in the 4.0 era as a distributed ledger technology. It can be transparency, traceability, security, immutability, and decentralization. This study aims to design a white sugar agroindustry system based on blockchain technology using the SDLC waterfall stage public. Ethereum is a proof-of-work convention based on the Ropsten test-net on the Metamask wallet. The sugar supply chain system that has been successfully developed allows consumers to track the purchased sugar products based on the transaction hash code sent by the seller. The data listed is the location of the plantation, the quantity (quintal) and quality of sugarcane (percentage), and the purchase price. A web-based blockchain application could be used as a model by national sugar factories to help them make enough sugar food for themselves.

Abstract

The fermentation of the coffee fruit processing into coffee beans leaves the fermented coffee pulp which still contains polyphenol secondary metabolites. This study aimed to analyze the total flavonoid content (TFC) and total phenolic content (TPC) of fermented robusta coffee pulp (Coffea canephora L.) by using indigenous Actinomycetes. The ability of fermented extracts to inhibit free radical DPPH (2,2-diphenyl-1-picrylhydrazyl) also were done. In this study, coffee cherries were fermented in the solid-state fermentation cultivation (SSF) using isolates HJ4.5b, P2b(b).3 and P2b(b).18 which in previous studies were reported to have cellulolytic and xylanolytic activities. Determination of molecular identification base on 16S rRNA gen showed the isolates HJ4.5b and P2b(b).3 have similarities to the genus Streptomycetes, while P2b(b).18 has a homologous base arrangement with a rare actinomycetes genus Micromonospora. Fermentation using P2b(b).3 on the 9th day of fermentation indicated the highest percentage increase in TFC (295.54%) with IC50 18.41 µl/ml and having an antioxidant activity index (AAI) value of 2.14 which was included in the very strong antioxidant activity category.

Abstract

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

Abstract

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 by  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, Streptomyces sp. S2, sugarcane bagasse

Abstract

The small and medium industries based on superior commodities potentially developed in Kampar Regency, as of its second-largest share contribution of GDP after the agriculture sector. The problem faced in developing small and medium industries is the diverse and varied nature of these enterprises, both in terms of quantity and scope, which leads to unfocused management of potential commodities and types of businesses. A technopark is one of the alternative strategies to develop small and medium industries based on superior commodities. Determining superior commodities is an initial step in developing small and medium industries through technoparks. The purpose of this study is to identify the superior commodities that will be developed in small and medium industries through technoparks in Kampar Regency, Riau Province. Data collection techniques were conducted through literature studies and expert interviews, using purposive sampling. The determination of commodities was done through LQ and SSA. The data used were horticultural crop production from 2017-2021. The study results indicate that pineapples are a superior commodity due to their extensive distribution in five sub-districts, boasting the largest harvest areas, abundant raw materials, and regional potential with LQ >1 and SSA > 0. The development of small and medium industries based on pineapple as a superior commodity through technopark can create economic value in the Kampar Regency.
