This study sets out to investigate the effects of ENR on the oil resistance property of nitrile rubber, NBR composites used for safety footwear application. Blends of NBR/ENR i.e. 100/0, 90/10, 80/20, 70/30, 60/40 and 50/50 were prepared and tested for their oil resistance property and other physical properties such as hardness, tensile properties and abrasion loss. Results showed that varying the amount of ENR did not significantly affect the hardness and tensile properties of the composites. Nonetheless, it was found that ENR content highly influences the abrasion loss of the composites in which the abrasion resistance decreased with further addition of ENR contents. Despite the increase in oil swelling of the composites with increasing ENR content, the oil swelling values are considered low (< 5% volume change), indicating superior oil resistance property of the composites. These results confirm the possibility of ENR as a sustainable material for the production of eco-friendly composites with high oil resistance property for the footwear industry.

Currently, environmental monitoring has become even more critical as human population increase, with the increasing strains on the environment. The unwanted synthetic compounds that presence from grey water in natural water was lead a toxic effect on ecosystems thus may lead to changes in biodiversity. This paper aims to discuss the studies of characterization in the environmental water sample from greywater which were laundry wastewater and car wash wastewater in the area surrounding Batu Pahat, Johor, Malaysia. The samples were directly brought to the laboratory for analysis and the content of grey water quality was characterized by using physicochemical analyses including pH, conductivity, suspended solids, chemical oxygen demand (COD), anionic surfactants (AS), oil and grease, sulfate, chloride, nitrate, and nitrite. All parameters were tested according to the standard method (APHA 2012). The result of this studies showed that the concentrations of AS by using methylene blue active substances (MBAS) were higher in laundry wastewater compared to car wash wastewater which was maximum at 105.0 mg/L. While the COD for car wash wastewater was maximum at 531.1 mg/L which was higher than laundry wastewater. Some of the characterizations indicated high values for many parameters and there is the need for specific treatment prior to discharge to before it has been directly discharged to the drainage.

These antibiotics have now been banned from use due to their carcinogenic properties; therefore there is an urgent need to remove or degrade NFs from contaminated areas. Aspergillus tamarii isolate TN-7 isolated from antibiotic overexposed soil shows an ability to degrade the NFs antibiotics. After 5 days of incubating of Aspergillus tamarii isolate TN-7 with 500 µg/mL NF, the residual of the NF concentration was determined by High-Performance Liquid Chromatography-diode array detector (HPLC-DAD). Solid phase extraction was performed to clean-up the fermentation broth prior to HPLC-DAD analysis. Antimicrobial of the NFs residues showed a decreased in the percentage of inhibition that FTD, FZD and NFZ were reduced to to 85.71 %, 75.86 % and 70.97 % after 96 hours of incubation. Quantification using HPLC-DAD showed, after 96 hours of incubation, Aspergillus tamarii isolate TN-7 reduced furaltadone, furazolidone and nitrofurazone to 86.73 %, 37.49 % and 29.17 % respectively. This finding shows that Aspergillus tamarii isolate TN-7 has the potential to be used as a bioremediation tool in removing NF antibiotics from the contaminated areas.

Therefore, this study has investigated the optimization of biodegradation of PS using isolated strain Bacillus aryabhattai as an alternative solution to the biodegradation of recalcitrant plastic. The effect of pH and temperature as independent variables were studied at three levels each (pH: 6, 7.5 and 9, temperature: 25 °C, 35 °C and 45 °C) under the designation by three level-factorial and analysed using response surface methodology (RSM) by Design Expert Version 10.0. The biodegradation activity of Bacillus aryabhattai was quantified using simple colorimetric method. Bacillus aryabhattai was inoculated on the dye PS-film and incubated under designed conditions. As a result of biodegradation, the entrapped methylene blue dye was released and measured photometrically. Optimum conditions for the highest reading of blue dye absorbance were obtained at pH 9 and temperature of 25ºC with the desirability of 75.9%. This study provides significant information on the biodegradation activity of Bacillus aryabhattai for future research that can be applied in waste management.

A. sessilis red was preserved using two different methods; freeze drying and superheated steam drying, followed by extraction with 70% ethanol using conventional extraction and ultrasonic-assisted extraction. Drying in the superheated steam oven displayed shorter drying period of 1 hour compared to freeze drying (several days). Combination of superheated steam drying and ultrasonic-assisted extraction showed the highest extraction yields (12.99%). Results showed that superheated steam drying and ultrasonic-assisted extraction displayed an increase in the total phenolic content. In terms of antioxidant capacity, A. sessilis extracts obtained from superheated steam drying has higher radical scavenging activity (72.39% - 76.70%) than those freeze-dried (60.68% - 65.33%). Meanwhile, ultrasonic-assisted extraction had negatively impacted the radical scavenging activity of the extracts due to the formation of free radicals that are related to acoustic cavitation. As for ferric reducing antioxidant power, both superheated steam drying and ultrasonic assisted extraction yielded extracts with greater capacity. Present result shows that the combination of superheated steam drying and ultrasonic-assisted extraction enhanced total phenolic content by 60% and improved antioxidant activity based on ferric reducing antioxidant power assay ","PeriodicalId":40905,"journal":{"name":"EMITTER-International Journal of Engineering Technology","volume":"135 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2019-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79550833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Natural colorants especially from plants have the advantage of being friendly towards the environment as the extraction, processing and dyeing procedures are considered green and safe. However, most natural dyes have poor colourfastness and needed mordants to improve their dyeability. In this study, the addition of Entada spiralis was utilized as a surface modifier to improve dyeability on 100% silk fabrics using extracts from red cabbage. The plant serves as a surface-active agent to reduce the surface tension of the fabrics. The surfactant is also a natural resource and therefore is not harmful to the environment. The Entada spiralis was extracted through boiling for 30 minutes on a hot plate before treating the extracts on the fabrics. During dyeing, lime was used as the mordant simultaneously with dyeing. The dyed fabrics were evaluated for colorfastness to washing, rubbing/crocking and perspiration using the Gray Scale Standard. In addition, the dyed fabrics were also measured for their colour strength, colour coordinates and % reflectance. The results showed that dyed fabrics with Entada spiralis have darker shades in comparisons with the untreated fabric.
