Abstract

ZA fertilizer waste (Ammonium sulfate) is waste generated from the industrial process of producing ZA fertilizer. The waste contains very high calcium and has the potential to be used as a raw material in the manufacture of Precipitated Calcium Carbonate (PCC). PCC with certain qualities can be developed in the field of advanced materials, with size modification into nanoparticles. One method to produce nanoparticles is using the coprecipitation method, with the help of a polymer solution. This study aims to produce Nano-PCC by finding the best conditions of CaCl2: Ethylene Glycol mole ratio and stirring speed. Nano-PCC is synthesized by reacting fertilizer waste with HCl to form a CaCl2 solution. Then, the solution is mixed with ethylene glycol to prevent particle agglomeration so that the size obtained will be smaller. The mixture is then reacted with Na2CO3 to form precipitated calcium carbonate (PCC). In this study, the variables were the mole ratio of CaCl2: ethylene glycol (1:12, 1:14, 1:18, 1:20) and stirring speed (350, 500, 650, 800, and 950 rpm). Based on PSA analysis, the Nano-PCC obtained at the smallest CaCl2: ethylene glycol ratio 1:12, stirring speed 950 rpm was 51.83 nm. Based on Scherrer’s calculations with XRD, the particle size obtained was 48.25 nm. SEM analysis showed that the crystals formed were dominated by vaterite crystals, with a size range of 55.71-607.79 nm.

Abstract

The degradation of azo is a challenge for environmentalists. Catalytic decomposition of azo dyes by ZnO heterogeneous photocatalysis and the influence of operating parameters such as light intensity, temperature, amount of ZnO catalyst, solution pH and amount of pollutants. It has been observed that ZnO catalysts is quite capable of removing azo dyes in the presence of sunlight. We can use the same catalyst over and over, and it works well every time. We recovered 99% clear water within a few hours of exposure to sunlight.

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

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

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.

Abstract

Bio briquette is a briquette based on agricultural waste because it is deliberately made from biomass charcoal. The utilization of agricultural waste such as mushroom planting media to be processed as bio briquette requires a very cheap cost. Bio briquettes that are processed properly and correctly, will produce high-quality briquettes. The purpose of this study was to produce a biobriquette from baglog mushroom waste and to determine the characteristics of the biobriquette. The research material used consisted of 400 grams of mushroom baglog waste and 40 grams of starch as adhesive. The briquette dough is then printed cylindrical. The printed briquettes are then heated at 80°C for 5 hours to reduce the moisture content. The result of smoke test is the smoke will stop in 17 seconds with the color of the smoke is white. The Combustion of speed test, the results obtained are 0,0019 gram/second with an initial sample weight of 2, 4 grams and burning for 20 minutes 35 seconds with a final sample weight of 0,387 grams. The result of ash content is 0.16%. This result is in accordance with the SNI issued by our government. SNI of ash content is max 8 %.

Abstract

Plastic food packaging has become a part of human daily life. The management of plastic waste is a matter of concern due to its potential which is difficult to decompose. This condition causes all producers to have a responsibility not only during the manufacturing process but until the end of the life of their products. This expanded responsibility is called EPR (Extended Producer Responsibility). Therefore the resulting packaging design becomes a breakthrough in this matter. This research attempts to apply the Kansei Engineering method to capture customers' emotional needs from consumers in compiling plastic packaging design parameters. The research method in this paper uses the Kansei Engineering method, namely by collecting Kansei words from respondents at random, then the Kansei words are reduced. The reduced Kansei word will be synthesized to produce quality attributes that are able to meet the customer's emotional needs. The Kansei words obtained from the survey results are 55 words. Packaging quality attributes that have met the customer's emotional needs include protection, refillable, recyclable, biodegradable, food safety, additional function, attractiveness, conformity, ergonomic, user friendly, and content declaration (on the packaging label).
