Summary The application of edible films can be an alternative solution for maintaining the quality post‐harvest horticultural commodities. This study aimed to determine effect adding a stabiliser, cellulose nanocrystals (CNCs), on functional characteristics citrus peel pectin and limonene essential oil (LEO)‐based coatings. A formulation comprising (0.5%), CNC (0.075%) LEO (0.5%) was prepared. morphology (nanometre scale) nanorods with pointed ends both sides, revealed atomic force...
In Indonesia, solid rubber is the most common form of natural (NR) intermediates because it easy to store and transport. However, hydrogenation, a process aimed at improving quality NR by addressing its vulnerability environmental factors due presence carbon double bonds, typically carried out under relatively mild conditions using latex material. This study explores biphasic hydrogenation approach dissolved in solvent hydrogen source (hydrazine hydrate peroxide) mixed water. The choice...
Summary Fruit loss frequently occurs due to physical and microbial deterioration. This study aimed develop an emulsified coating formulation based on pectin (BP)/cellulose nanofibre (CNF)/(peppermint essential oil) PEO using the Pickering technique with appropriate level of CNF as a stabiliser its effect grape quality during storage. The incorporation 0.4% PEO‐stabilised various 0.1%–0.325% into 0.5% BP edible coatings was developed. A 0.175% concentration found be for stabilising emulsion...
Abstract Microplastics have become a serious threat to the aquatic environment, water treatment facilities, and riverside residents because they are persistent. generally come from plastic waste produced by human industrial activities that enter rivers. In this study, Cisadane River was studied for microplastic presence. Sampling conducted at 11 points along upstream (Muria Jaya) downstream (Teluk Naga). Samples were taken using 200-mesh plankton net then analyzed digital microscope...
The differences in the curing characteristics and physical properties of natural rubber samples using clay modified as fillers were studied. After was with dodecylamine, milling process conducted at a temperature 65–70
Abstract The process of making traditional salt generally uses sea water sources. marine environment is currently a global concern due to the presence microplastic contamination. Meanwhile, microplastics were also identified in table salt. In this work, sampling was carried out on areas Takalar Lama - South Sulawesi and Woha West Nusa Tenggara which are famous for making. Samples taken starting from as source, saturated coarse identification microdebris using filtering drying method....
Abstract Microplastic is widely discussed and has become growing attention because of its negative impact on the environment well-being living organisms. Some international studies have found microplastics in some foods beverages, such as honey, beer, table salt, drinking water. However, there are few accurate analytical techniques for identifying analysing microplastics, especially beverages foods. This preliminary study investigates that might contaminate bottled water, their physical...
Abstract Modern Fish Market of Muara Baru is one the largest fish markets in Jakarta, which sells various seafood, including fish, shellfish, crustaceans, and others. Previous studies have revealed microdebris contamination mollusks, particularly filter-feeders. However, it has not been widely studied at predator level cephalopods. We aim to investigate two commercial species cephalopod, i.e. Loliolus sumatrensis Sepia recurvirostra , from market. The digestive tract cephalopod was taken...
In biodegradable polymer nanocomposite, the important factors to determine its properties are polymer, materials and nano filler. case of filler organo layer silicate (OLS) interlayer gallery also plays an role. This research is intended study effect surfactants OLS by sonication. Glycerol monostearate (GMS) gum rosin (GR) were used increase or intercalation temperature stability as it provides advantage for ease exfoliation process. The relationship between surfactant was examined X-ray...
Degradable plastic is a topic that continues to be discussed, especially for disposable applications. Blending starch with commercial plastics such as Linear Low Density Polyethylene was the alternative developed. The degradation mechanism of biopolymer may occur microorganisms and also through exposure sunlight or Ultra Violet light. In this work, test on Linier Polyethylene-starch-clay nanocomposite film conducted Xenon Arc. Nanocomposite samples were prepared from masterbatch clay 10% wt...
Starch blending with linear low-density polyethylene (LLDPE) is one of the plastic packaging materials alternative used for solving waste problem that difficult to degrade.Polymeric will change when exposed weather releases heat, chemistry, and light.It can be a trigger factor in degradation process.Xenon Arc accelerated simulation test way find out resistance weather.This study aimed explain effect xenon arc light on LLDPE-starch-clay composite.In this work photodegradation tests using...
In order to improve the mechanical properties of natural rubber so it can be used as raw material for industrial component, is required add filler and coupling agent rubber. previous study, carbon black obtained from sonofication process 3 5 hours was added (filled) thermal rubber-carbon black, where improvement influenced by period which subsequently composite.In this various composites have been synthesized using thin pale crepe (TPC) matrix, strengthened N 660, sonoficated addition 2 phr...
Abstract Microdebris contamination of marine organism has become a major concern. As detritivore, Tripneustes gratilla also the opportunity to be contaminated. This study aims determine microdebris in T. , including form and size microdebris. research was conducted at three islands, i.e. Barrang Lompo, Badi, Kondong Bali. Ten individuals were collected from each island. The digestive tract spesies taken, then H2O2 added dissolve organic matter. Flotation carried out by adding NaCl. observed...
Incorporating multi wall carbon nanotube (MWCNT) into the polymer can improve electrical properties of nanocomposites. The effects MWCNT on and rheological polypropylene/MWCNT (PP/MWCNT) nanocomposites are investigated. were prepared using melt mixing technique at chamber temperature 180°C rotor rotation 100 rpm for 10 minutes. Addition increases surface conductivity up to 10−7 S. percolation threshold is found occur 1.3 wt% content. Viscosity increased with addition MWCNT. PP/MWCNT 1.4 Well...
Abstract Bivalves can accumulate various particles, including micro debris. Unfortunately, no study has been recorded the marine debris on consumed bivalves. We aimed to investigate in Perna viridis, Andara granosa , and Marcia hiantina from major fish market at Jakarta Makassar. Ten individual tissues for each species were taken added with H 2 O a concentration of 50% then solution was placed thermoshaker 60°C accelerate dissolution process. Concentrated NaCl flotation process extracted...
Biodegradable polymer using inexpensive renewable resources such as starch produced poor mechanical, barrier properties and transparency of product, these were the important parameter for packaging material. This research intended to study effect glycerol monostearate (GMS) treated organo layer silicate (OLS) in biodegradable masterbatch eliminate inferior properties. Focus was morphological structure clay nanocomposite. nanocomposite prepared Haake Rheomix Polydrive at a temperature 100 °C...
