Abstract

Energy consumption will continue to increase in the coming years. While the national energy reserves will be depleted if no new energy reserves are found. One of the renewable energy that has great potential in Indonesia is biomass. The biomass can be processed into biobriquette, which is a fuel with a high level of heat value. The skin of peanut is one of the household industrial waste that has energy value. The skin of peanut contains a lot of cellulose, so it can be used as briquette fuel. In this study, the independent variables used were carbonization temperatures, ranging from 3000C, 3500C, 4000C, 4500C, 5000C, 5500C. While the fixed variable is carbonization time for 5 minutes, and the composition used is 90 grams of charcoal and 10 grams of adhesive starch solution. From the research, briquettes have optimum quality with carbonization temperature of 450 0C with heating value of 6795 cal / gr, moisture content of 7.28%, ash content of 8.21%, levels of flying substances 19.12%, and carbon content solid 65.39%.

Abstract

Tofu industrial activities in Indonesia are dominated by small-scale businesses with limited capital and production which is still done with simple technology. Tofu liquid waste contains a lot of organic and inorganic compounds that can disrupt the microbial life in water and pollute the environment,so that it needs treatment before being discharged directly into water. Phytoremediation is one alternative method of wastewater treatment processes by using plants or microorganisms as hyperacumulator. This study aims to determine the length of the absorption process of kiambang (salvinamolesta) and determine the influence of the weight of kiambang (salvinamolesta) in reducing the levels of COD and TSS in tofu’s wastewater. Waste treatment usesbucket as media with volume 5 L that is filled by liquid waste out with composition 1: 5 (tofu’s wastewater : water) and volume 3 L. Variables in this research areweight of kiambang(100 g, 250 g and 500 g) and absorption’s time (2 days, 4 days, 6 days and 8 days). The results showed that the best length of time of absorption is about 8days to decrease level of COD and TSS, with a percentage degradation of COD TSS 87.10% and 98.46%. And the best weight of kiambang to decrease levels of COD and TSS is about 250 g.

Abstract

The purpose of this research is to determine the effectiveness of activated carbon from bagasse with activator subtances HCl and CaCl2 in reducing the parameters of COD and TSS and increasing the DO and PH parameters in the tofu processing waste. The optimum conditions in reducing the COD and TSS parameters and increasing the DO and PH parameters in the tofu processing waste are 12 hours of circulation time with a fixed bed reactor. The results of the study with the use of 0.3 M HCl activator has a better ability than 0.2 M CaCl in reducing COD and TSS values and increasing DO and PH values.The results ofusing activator substances HCL 0.3 M has a better ability than 0.2 M CaCl in reducing COD and TSS values and increasing DO and PH values. The decrease in COD value from 123.7 mg / L to 41.6 mg / L or 66.37%, a decrease in TSS value from 335 mg / L to 103.8 mg / L or 69.1%, an increase in DO value from 1.86 mg / L to 7.6 mg / L or 75.52%, and the increase in pH value from 3.53 to 4.66.
