Abstract

The purpose of this study was to determine whether chinese water chestnut (Eleocharis dulcis) could be used as activated charcoal as a peat water biofilter and to determine the effect of carbonization time on the quality of activated charcoal from chinese water chestnut (Eleocharis dulcis). The experimental method used in this study was a single factor Completely Randomized Design (CRD) with 6 treatments, namely differences in carbonization time (30 minutes, 1 hour, 1.5 hours, 2 hours), factory charcoal (positive control) and no treatment. (negative control). The results showed that activated charcoal of chinese water chestnut (Eleocharis dulcis) can be used as a biofilter of peat water and carbonization of 2 hours (A5) is thought to be the most optimal time for the quality of activated charcoal of chinese water chestnut (Eleocharis dulcis) which is indicated by the parameters of ash content of 0.367% and iodine absorption. 1910.126 mg/g.

Abstract

The purpose of this study was to determine the effect of water lily activated charcoal as a biofilter in tofu wastewater treatment and to determine the effective dose of water lily activated charcoal as a biofilter in tofu wastewater treatment. The results showed that water lily activated charcoal can be used to improve the quality of tofu liquid waste; thus, it can improve the quality of tofu liquid waste which can be seen from the parameters of TSS (Total Suspended Solid). The treatment dose of 2 g of activated charcoal (A3) is the best dose to improve the quality of tofu liquid waste and has complied with the 2014 LH regulation concerning the quality standards of wastewater for the tofu industry, namely the parameters of TSS. The existence of this research can be a reference for further similar research by utilizing organic matter as an alternative in tofu wastewater treatment.

Abstract

The depletion of fossil fuels and the increase in greenhouse gas emissions have sparked public concern. Along with the problems occurred, the need for energy continues to increase, while energy source reserves are decreasing. This research was conducted with an aim to determine the effect of the addition of Ni-Fe/NZA catalyst on bio-oil yield from the pyrolysis process of sugarcane bagasse waste. Chemical analysis was carried out using GC-MS instrument and physical analysis was carried out using a pycnometer, viscometer, pH meter, and bomb calorimeter. The results showed that the bio-oil produced had better quality as evidenced by a series of chemical and physical analysis, so bio-oil can be used as a renewable alternative fuel with dominant compounds in the form of furfural and acetic acid. The highest bio-oil yield was obtained at 1% catalyst weight percentage and at the temperature of 400℃ of 48.1%. The density of bio-oil had a range of 0.93-1.01 gr/mL, bio-oil viscosity ranged from 25.75-30.01 cP and Bio-oil pH ranged from 2.62-3.27. The fastest first drop of bio-oil was obtained at 105℃. The calorific value had a range of 20.26-27.05 MJ/kg. It can then be concluded that Ni-Fe/NZA has great potential as a catalyst in the pyrolysis process and improves the quality of bio-oil produced in the development of sustainable technology.
