Abstract

Environmental pollution relates to exposure to pollutants that disrupt the natural environment and can affect living things in the environment. One of the most dominant pollutants in the mining business is heavy metals such as mercury (Hg) which is classified as a hazardous toxic material. The purpose of this study was to measure the levels of mercury (Hg) contained in samples of Ongkag Mopusi River water in South Tanoyan village using AAS. Based on the results of research on Ongkag Mopusi river water samples in South Tanoyan Village using Atomic Absorption Spectrophhotometer (AAS), the lowest Hg exposure was obtained at point B3 of 0.00002 ppm and the largest at 0.0001 ppm. from these results it is concluded that Ongkag Mopusi river water in South Tanoyan Village is still in accordance with the quality standards set by Government Regulation No. 82 of 2001 concerning Water Quality Management and Pollution Control, where the allowable mercury threshold for category I water is 0.001 mg/L.

Abstract

Liquid smoke has been widely applied in various fields. Several studies have developed methods, tools and materials for making liquid smoke. This research aims to design a tool for making liquid smoke using a simple pyrolysis method on a laboratory scale. The goal is that this tool can be used by students for practicums to further increase students' insight and skills regarding liquid smoke. The stages of this research start from literature study, technology design, tool fabrication and testing as well as the evaluation stage. The results obtained in this research are that a liquid smoke pyrolysis device has been successfully made with a capacity of 6 kg. Based on the test results, grade 3 liquid smoke was produced.

Abstract

Daluga (Cyrtosperma merkusii) starch processing yields waste with 70% of its total weight consist of organic biomass materials that can be utilized as advanced composite biomass materials, a potential base for reinforcing materials. Processing the Daluga waste (debris) requires stages of pretreatment and activations to eliminate inhibiting agents within the hydrolisis process (fermentation process). The purpose of this research is to understand the effects of biological pretreatments using the Effective Microorganism (EM4) bacterial consortium towards the chemical properties of Daluga debris. The chemical compositions of debris Daluga before and after each treatment were determined by NDF and Van Soest method for observing the cellulose, hemicellulose, lignin, fiber, ash content, crude protein, silicate and crude fat. These parameters were analysed following the methods outlined in the Indonesian National Standard (SNI 01-2891-1992) and while protein and carbohydrate content was measured with the Dumas combustion method. Results indicated that lignin concentration after delignification process decreased considerably to 1.80 ± 0.07% although lignin content of these Daluga debris initially wasn’t so high to begin with 4.11 ± 0.02%. Herewith, hemicellulose also decreased giving an appearance for the increase and exposure of cellulose. Thus, providing a clear path to further processing the cellulose to advance cellulosic materials such as cellulose nano crystals (CNC).
