Abstract

process in water helps reduce solid content in water. The coagulant destabilizes water pollutants and helps flocs formation with the coagulation process. This paper studies the performance of chitosan bio-coagulant produced from Corbula faba Hinds shells. The velocity gradient and the Camp number of solids removal were also evaluated. The velocity and period of rapid mixing varied from 110 to 150 rpm, and the velocity gradient (G) was 181.2 to 288.5 s-1. The mixing period also ranged from 1 to 5 minutes. The highest TSS and TDS removal resulted in 140 rpm or 260.2 s-1 and 4 minutes of mixing. The residual TSS and TDS decreased with the increase of Camp Number until reaching a point and increased again afterward.

Abstract

The aim of this research was to analyze the chemical characteristics of Velva products from the mixture of bananas and blueberries with the addition of CMC. This study used a two-factorial completely randomized design with the first factor being the proportion of bananas and blueberries (40:60, 50:50 and 60:40). The second factor was concentration of CMC (0.1, 0.3 and 0.5%). Chemical analysis in this research included total acid, vitamin C, antioxidant activity, crude fiber content, protein, and fat. The data were analyzed by ANOVA using SPSS version 26 with Duncan Multiple Range Test at 5 % probability level. The best results based on the best chemical characteristics were obtained in the treatment of banana and blueberry proportions of (40:60) and CMC concentration of (0.5%) which had characteristics 0.613% total acid, 7.627 mg/100g vitamin C, 42.893% antioxidant activity, 4.450% crude fiber, 3.657% protein and 0.127% fat.

Abstract

Coriander is one of the natural antioxidant sources that can be used as chelating agent of heavy metals, such as lead (Pb) due to the presence of its phenolic compounds. However, the coriander has only been used as one of the spices on some dishes, and the other potential benefits have not been widely explored. Therefore, the processing of coriander leaves into a ready-to-drink (RTD) powdered beverage would be one of the ways to utilize the coriander. The objective of this study was to analyze the effect of drying temperature and maltodextrin concentration on product quality of powder drink. This study applied a complete randomized design of factorial pattern with two factors. The first factor was the drying temperature of 40oC, 50oC, and 60oC, while the second factor was the addition of maltodextrin as filler with the concentration of 5%, 10%, and 15%. The optimum treatment was observed at drying temperature of 40oC with maltodextrin concentration of 15%, yielding powder drink with water content of 4.19%; solubility of 89.92%; total phenol of 131.93 mg TAE/g; primary antioxidant activity of 47.05%; secondary antioxidant activity of 79.30%; and Pb reduction ability of 95.36%.

Abstract

Hydroxyapatite is a calcium phosphate compound that is the main inorganic component of bones and teeth. Hydroxyapatite has a main role in the medical world because of its identical chemical properties and structure to human bone. Kupang shells have a high CaCO3 content of 95-99% by weight. So this concurrence, the mussel shells are to be used as good as an ingredient for making Hydroxyapatite. The variables used in this research are Temperature of the Furnace and Phosphoric Acid Concentration, which were 700ºC, 750 ºC, 800 ºC, 850 ºC, 900 ºC and Phosphate Acid Concentrations 0.4M, 0.6M, 0.8M, 1M, and 1.2M. The product results were tested with XRD analysis to determine the crystal structure contained in the product and the level of Hydroxyapatite in the product. The best research results in this study at a temperature of 900ºC at a concentration of 1.2M phosphoric acid with a Hydroxyapatite content of 100% with lattice parameters an (Aº)=b (Aº) = 9..422, c (Aº)=6.8835, and gamma = 120º.

Abstract

Herein, we reported the synthesis and corrosion inhibition studies of poly (N-tert- amylacrylamide-co- N-phenyl acrylamide) copolymers. The copolymers are synthesized by free radical polymerization using NTA and NPAM monomers . The synthesized copolymers are subjected to corrosion inhibition behavior by EIS and PDP methods. Both the methods showed same results of 85.0 percentage of inhibition.

Abstract

Fe3O4 Nanocomposite Hydrogels were prepared by free radical polymerization using N-tert-amyl acrylamide , Acrylamide and Sodium acrylate monomers at 60OC. Fe3O4 NPs was intercalated via in situ method. The synthesized nanocomposite Hydrogels conformed by FT-IR spectroscopy. Surface morphology of the nanocomposite hydrogels indicated the ferrate nanoparticles are intercalated uniformly throughout the polymer matrix. The XRD pattern of the hydrogel showed the presence of nanoparticles in the matrix with certain crystallinity nature. UV-visible absorption studies reveal the catalytic activity of Methylene Blue dye molecules in the aqueous medium by the Nanocomposite hydrogels.
