Abstract

The Research has been carried out on the making of silica gel from rice husk ash with strong and weak acid reagents using variations in the amount of silicate ash as much as 50, 100, 200 and 300 grams by using hydrochloric acid, nitric acid, acetic acid and citric acid as solvents. This study aims to obtain the effect of the type acid and variations in the amount silicate on the characteristics of silica gel products and as a method of applying adsorption to H2O. The silica gel test resulted from the yield test, water content, ash content, I2 adsorption power, application of adsorption power to H2O and the best product test using FTIR. The more amount of silicate used will affect the quality of silica gel obtained from the results of testing and calculations, optimal result silica gel obtained with amount of silicate ash is 50 grams. The higher amount of silicate ash used, the results obtained will increase. Optimal results obtained from silica gel in hydrochloric acid with the amount of silicate ash 50 grams, where the yield is 17.86%, water content is 4%, ash content is 11% and I2 adsorption power is 1218.24 mg/g. The application of H2O adsorption power is obtained the more amount of silicate used, the higher H2O absorption results. Optimal results obtained from silica gel in hydrochloric acid with the amount of silicate ash 50 grams, where the adsorption power of H2O is 9.6 mL/g. And finally, the best product test using FTIR is hydrochloric acid and nitric acid.

Abstract

Biodegradable foam made from starch is an alternative packaging to replace styrofoam, but foam made from starch is very fragile, sensitive to water. Additional treatment is required to increase strength, flexibility and resistance to water for commercial application. The addition of rice straw cellulose as a filler to improve the properties of the resulting biofoam. Rice straw that has been fermented using MA-11 is then washed and sieved using a 100 mesh sieve to produce cellulose. The process of making biodegradable foam uses the extrusion method. The variables used were the ratio of cassava starch and rice straw, namely 40:60, 45:55, 50:50, 55:45, 60:40 % w/w with variations in cooking time, namely 30 minutes, 40 minutes, 50 minutes, 60 minutes, 70 minutes. The results of biodegradable foam testing from cassava starch and rice straw obtained values of tensile strength, compressive strength, water absorption, and biodegradability. The tensile strength and compressive strength tests for all biofoam samples did not meet SNI standards. The results of the water absorption test that met the SNI standards were sample 45:55 minutes 30 with a value of 26.72%, and the results of the biodegradation test met the SNI standards, namely the sample 60:40 in 30 minutes with a value of 82.27% with a biodegradation time of 7 day.

Abstract

A study was done to determine the effect of activator type on the properties of activated carbon generated from sugarcane bagasse. The goal of this research is to examine the effect of activator type and activation period on the quality of activated carbon derived from sugarcane bagasse. This study's procedure began with the manufacture of activated carbon from sugarcane bagasse. The dried sugarcane bagasse was heated until it produced charcoal. In 150 cc of each activator solution, 10 g of charcoal were dissolved. It was then heated and left for the set activation time treatment. Three experiments on the properties of activated carbon were performed, namely moisture content, ash content, and iodine adsorption capacity (I2) for activation times of 6 hours, 9 hours, 12 hours, 15 hours, and 18 hours. According to the findings of this study, the kind of activator had little effect on the moisture and ash content of activated carbon, but it had a considerable effect on the iodine adsorption capacity of activated carbon. Furthermore, the activation duration influences the moisture level, ash content, and iodine adsorption capacity of activated carbon. The moisture material, ash content, and iodine adsorption ability (I2 ) of activated carbon (AC) from sugarcane bagasse satisfied the criteria of the Indonesian National Standard (SNI) in this study. Bilimbi (Averrhoa bilimbi L.) was the most effective activator in this investigation, with an engagement time of 6 hours.

Abstract

The use of of cellulose from wood is growing every year in Indonesia. Continuous environmental harm results from this. In this study, paper was made using bacterial cellulose activator, tapioca flour, and coconut water as basic materials to make it more environmentally friendly. In this study, the impact of bacterial cellulose mass and tapioca flour mass on the final paper was examined. The amounts of 100, 125, 150, 175, and 200 g of bacterial cellulose and 5, 10, 15, 20, and 25 g of tapioca flour were the variables employed in this study. Additionally, the finished paper is tested for gramage, tensile strength, water content, functional group (FTIR), and a SEM test. According to the grammage test results, combinations of 100 g of bacterial cellulose and 25 g of tapioca flour had a higher grammage value than the others, 75 g/m2. The mass variation of 100 g bacterial cellulose with a mass of 25 g tapioca flour had the highest value in the tensile strength test, with a value of 0.808803 Mpa. In contrast, the mass variation of 100 g bacterial cellulose with a mass of 25 g tapioca flour had the greatest value in the water content test with a value of 5.91%.
