Abstract

Poly(lactic acid) (PLA) is a promising candidate as a renewable resource for plastic production. The use of PLA as a plastic material helps alleviate issues associated with waste. In the production of Polylactic Acid (PLA), by-products such as water are generated, and the Lewis acid catalyst used in PLA production is susceptible to rapid decomposition and deactivation by water. This research aims to optimize PLA polymerization using a water-resistant catalyst, Al(DS)3, to achieve an optimum PLA molecular weight.The synthesized PLA is then analyzed using viscometry to determine its molecular weight. Optimization is carried out using the Response Surface Methodology (RSM) with a Central Composite Design (CCD) matrix. The molecular weight of the synthesized PLA is measured through viscometry, and the data is input into Minitab to obtain the optimum point. This optimum point is further validated by calculating the error value from the optimization results. The optimized PLA results in a molecular weight of 10.313 g/mol with an error value of 4.47% at a catalyst concentration of 0.15% and an operating temperature of 180 °C.

Abstract

This research aim is to determine the performance of coconut fiber-based cellulose aerogel impregnated with zinc oxide for wound dressing applications. Cellulose is an alternative material in aerogel synthesis. Cellulose aerogel is the latest third generation in aerogel research which has attracted much attention due to its good prospects, especially in terms of environmental friendliness and price effectiveness. The synthesis of cellulose aerogel begins with the cellulose purification stage through delignification and bleaching, followed by the addition of NaOH-urea solution, freeze drying and the final stage is impregnation with zinc oxide. Zinc oxide (ZnO) has nontoxic, safe and biocompatible properties and functions as an antibacterial agent. The cellulose/ZnO aerogel formed was subjected to performance tests including analysis of porosity, water absorption capacity, water vapor permeability and antibacterial tests. Based on research that has been carried out, it was found that coconut fiber-based cellulose aerogel impregnated with ZnO has a good potential as a wound dressing application. The porosity of the resulting cellulose aerogel can reach above 90% with high water absorption capacity and has a water vapor permeability which increases with increasing cellulose concentration. Antibacterial tests show that the cellulose/ZnO aerogel has good antimicrobial characteristics.

Abstract

This study aims to measure the liquid-liquid equilibrium of the ternary system of propionic acid + H2O + 1-pentanol and propionic acid + H2O + 1-hexanol at temperatures of 303.15 and 323.15 K at atmospheric pressure. The primary equipment used in this study is an equilibrium cell with a heating jacket. The experiment lasted for 24 hours with time weighting, which included 4 hours of stirring using a magnetic stirrer. The remaining 20 hours were allotted for the solution to settle until perfect equilibrium occurred. Gas Chromatography with an FID-type detector was used to analyse the experimental results for composition. Other variables were tested by conducting experiments and the results were plotted on a ternary diagram with 8 tie lines for each system. The ternary diagram indicates that both systems adhere to the Treybal type I. The NRTL and UNIQUAC equations were used to correlate the research data from each system, resulting in a Root Mean Square Deviation (RMSD) of 3.20% of the equilibrium composition for each system.

Abstract

The oxygen delignification of cassava stem waste (Manihot esculenta crantz) kraft pulps were studied under vary conditions. Kappa number and viscosity are two important parameters for the quality of resulting pulp, which are influenced by some operation conditions. Therefore, it is important to observe and examine the Kappa number and viscosity beforehand. The aim of this study was to obtain a prediction of the Kappa number and viscosity for various conditions and to obtain the excellent condition for producing qualified pulp. The prediction was carried out by governing kinetic model of oxygen delignification reaction from experiment data. Based on analysis of prediction, the optimum condition was reached at pressure of 2 bar, alkali charge of 2%, temperature of 80 oC, and reaction time of 53 minutes with pulp viscosity of 878.73 ml/g. In addition, the experimental data matched well to the prediction data obtained from kinetic model.

Abstract

Indonesia is one of the countries that produces porang tubers in the world The biggest benefit of cultivating porang plants is to obtain the tubers. The harvested porang tubers can be sliced or chipped and then dried. Porang slices or chips can then be processed into konjac flour or konyaku. From konjac flour, glucomannan can be obtained. The aim of this research is to make jelly candy from porang flour which will be purified first by an extraction process using ethanol. The research method used was to extract 70 g of porang flour using foodgrade ethanol with a concentration of 50% as much as 560 ml by stirring on a hotplate at 30 ℃, stirring speed of 600 rpm and stirring time ( 30 minutes, 60 minutes, 90 minutes) which will then be filtered to obtain porang flour precipitate then in the oven for 12 hours with a temperature of 90 ℃. From the research results, it was found that the best glucomannan content was at a stirring speed of 600 rpm for 60 minutes, namely 81,52 %. Then, the best results of glucomannan flour were applied by being used as an ingredient for making jelly candy added to carrageenan.
