Abstract

Palembang Jumputan Fabric, or commonly called Rainbow Fabric, one of the crafts produced with the jumputan technique, (Tie and Dye) is a technique of dyeing fabric by dipping it in colored ink, by adding silk and satin materials with a natural mixture of coloring method of natural and chemical origins. There have been many studies regarding the treatment of jumputan fabric wastewater using adsorbents, but this method has a weakness. Similarly, it allows the adsorbent to be left behind in the jumputan fabric wastewater. The purpose of this research is to treat the liquid waste of jumputan fabric with polysulfone membrane to reduce dry stuff . The membrane will be made using DMAc solvent and a PEG 400 additive with a composition of 18% polysulfone; 62% Dmac; and 20% PEG. The liquid waste of jumputan cloth will be purified with polysulfone membrane by ultrafiltration.

Abstract

Heavy metals can cause environmental pollution and affect human health. Cu and Zn are often found in the environment. One method to reduce Cu and Zn is to use the adsorption method. Adsorption has become a competitive method in the field of wastewater. Adsorption kinetics is one of the main factors that must be understood before the application of any adsorbent. In each adsorption process, linear or non-linear analysis of the kinetics was applied. A fit index (correlation coefficient or sum of squares) was applied to access the best model. The purpose of this study was to determine the adsorption equation model, to obtain the adsorption kinetics of Cu and Zn metals using a silica membrane. The methodology used is silica extraction by precipitation method and then the process of making PVA and PEG membranes as adhesives and solvents. For the analysis of metal concentrations of Cu and Zn, Atomic Absorption Spectrophotometry (AAS) was used, while for membrane morphology analysis, a Scanning Electron Microscope (SEM) was used. From the process of applying silica membrane to palm oil liquid waste, the results of Pseudo Order 1 absorption kinetics for Cu metal (artificial solution) with k value of artificial Cu metal (4M) 0.0596, and k value of artificial Cu metal (8M) 0.0022, while the Pseudo Order 1 absorption kinetics for Zn metal with a k value of Zn metal (4M) 0.0077, and a k value of Zn metal (8M) 0.0109.

Abstract

Rice husk ash (RHA) produced from combustion at high temperatures has the main composition of silica (SiO2) which makes ASP as a potential catalyst support in the triglyceride transesterification process to increase the activity of CaO catalyst. CaO is one of the most popular types of heterogeneous catalysts because it is easily found in nature such as egg shells. Because CaO has drawbacks such as low reaction rate, easy reaction with air, and leaching, which reduces its catalytic activity and reduces biodiesel yield, for this reason, it is necessary to insert alkali metals such as K from KOH and rice husk ash as support. This study aims to obtain heterogeneous CaO/KOH/ASP catalysts with high catalytic activity, determine the optimal ratio of CaO/KOH/ASP catalysts and determine its characterization based on the yield and quality of biodiesel produced and produce biodiesel that meets SNI. In this research, the catalyst manufacture was carried out using the wet impregnation method, where the mass of CaO:ASP with varying masses (0:10, 2.5:7.5; 5:5; and 7.5:2.5) was immersed in a KOH solution which was also varied. concentrations are 25%, 30%, and 35%. The catalyst was then calcined to be activated and tested in the manufacture of biodiesel. In this study, a catalyst with high catalytic activity was obtained with the optimum ratio at CaO:ASP 2.5:7.5 and KOH 25%, where the biodiesel yield obtained was 94.62% with a density of 0.876 gr/ml, viscosity 3.75 cSt, flash point 151.10C, cetane number 66.99 and methyl ester content of 96.21%. The quality of biodiesel produced has complied with SNI.
