Abstract

Agar is polysaccharide extracted from the seaweed Gracilaria sp. It is commonly used for food, medical, pharmaceutical and biotechnology industries. The red seaweed Gracilaria verrucosa is the most common material used for the extraction of agar, processed into sheet and powder. A total of 7169 tons solid waste is produced from the agar industry in Indonesia which can further result in 4301.4 tons per year of cellulose. However, solid wastes from agar seaweed processing industry have not been managed and used optimally, and therefore seaweed solid wastes can be used as one of alternative source of cellulose and cellulolytic bacteria. In this research, we reported the isolation of cellulose-producing bacteria from seaweed processing industry wastes using specific media 1 % LIA (Limbah Industri Agar, waste of seaweed processing industry). Sequencing and subsequent phylogenetic analysis of the 16S rRNA genes amplified from the obtained 7 isolates identified them as Serratia marcescens, Chryseobacterium indovlogenes, Bacillus pumilus, Bacillus cereus, Strenatrophomonas maltophila, and Pseudomonas aeruginosa.

Abstract

The bioactive components of malacca (Emblica officinalis), which consist of phenolic, alkaloids, phytosterols, organic acids, and vitamins, are valuable for human health. The yield and quality of the bioactive components in the extract highly depend on the extraction technique, so it is essential to know the development of research on extraction techniques of the bioactive components of malacca fruit. In addition, the bioactive components in the extract have limitations in their application due to their stability, solubility, absorption, and bioavailability properties. Currently, nanoencapsulation technology has been applied to extracts of bioactive components to improve their properties. This review aims to provide comprehensive information about extraction techniques to obtain bioactive components of malacca fruit and presents the technique and purpose of the nanoencapsulation of malacca fruit extract. In addition to conventional techniques, several modern extraction techniques such as microwave-assisted extraction (MAE), ultrasound (UAE), pulsed electric field (PEF), and supercritical fluid (SFE) have been used to extract bioactive components of malacca fruit. Modern extraction techniques can produce extracts of bioactive components with higher yields than conventional techniques. The application of nanoencapsulation technology to malacca fruit extract consists of nanoliposomes and nanoparticles can increase permeability, antioxidant activity, antidiabetic and anti-inflammatory properties of malacca fruit extract.

Abstract

This study was conducted to evaluate the performance of Curcuma zanthorrhiza crude extract after encapsulated in nanocrystalline starch, and to investigate the effect of the ratio of nanocrystalline starches and maltodextrin; and the effect of concentration of temulawak extract on nanocapsule characteristics, as well as encapsulation effect on the stability of antioxidant activity. Preparation of nanocrystalline starch was conducted by using lintnerization and ethanol precipitation of cassava and sago starches. Nanocrystalline starch and maltodextrin were used as matrices with the ratio varied from 25:75, 50:50, and 75:25. The mixture of temulawak extract and matrices were homogenized and spray dried. Nanocapsules characteristics included the efficiency of encapsulation and drug loading, and antioxidant activity test were investigated. Nanocrystalline cassava and sago starches were potentially modified starch that can be used as the matrix for its low solubility and digestibility. It showed that the ratio of nanocrystalline starch, maltodextrin, and concentration of temulawak extract significantly influenced the nanocapsule characteristics. The best encapsulation condition obtained for nanocrystalline matrix from cassava starch with the ratio of nanocrystalline starch: maltodextrin 25:75 (%w/w) and 10% concentration of the temulawak extract, while for sago are 75:25 (%w/w) and 10% concentration of temulawak extract. Nanocrystalline matrix from cassava starch revealed higher encapsulation efficiency and antioxidant activity. The use of high temperatures during spray drying affected by the slight decline of antioxidant activity of encapsulated temulawak extract. Encapsulation of temulawak extract by using nanocrystalline starch and maltodextrin could retain and protect its antioxidant activity.

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.
