Abstract

The Kambang River is a river in Jambi City that passes through densely populated residential areas and shopping centers, making it vulnerable to pollution from both point and non-point sources. This study aims to model the water quality of the Kambang River using QUAL2Kw software on the Biochemical Oxygen Demand (BOD) and Ammonia as nitrogen (NH3-N) parameters in response to increasing discharge and pollutant levels from point sources. Sampling was conducted using grab sampling at nine points representing the upstream, midstream, and downstream segments. The test results were compared with the river water quality standards and similar waters, Class II, Appendix VI of Government Regulation No. 22 of 2021 concerning the Implementation of Environmental Protection and Management. River hydraulic data (discharge, width, depth, flow velocity, and riverbed slope) were used as input data in the QUAL2Kw worksheet. Data calibration was performed using trial and error, then data validation using the Root Mean Square Percentage Error (RMSPE) method. The results of water quality testing showed that the BOD and NH3-N parameters at all sampling points did not meet the established quality standards. The BOD test value ranged from 7.10 to 16.20 mg/L with a quality standard of 3.00 mg/L, and the NH3-N test results ranged from 3.03 to 14.13 mg/L with a quality standard of 0.20 mg/L. The model validation results using the RSMPE method for discharge parameters were 3.21%, BOD 3.88%, and NH3-N 0.46%, meeting the criteria of

Abstract

Cans of soft drinks are a source of waste in Indonesia, as this inorganic waste cannot be decomposed rapidly and naturally. Aluminum takes about 400 years to decompose in the soil. A large amount of aluminum contained in the cans can be reused as goods or raw materials to produce hydrogen gas. Hydrogen is considered an environmentally friendly fuel regarding its very low emissions and high energy value. The hydrogen gas production process involves a reaction between aluminum metal and a catalyst. In this case, the use of a strong base catalyst such as KOH has been shown to produce more hydrogen. This experiment aims to utilize the cans as a material to produce hydrogen gas. This experimental process was carried out by reacting aluminum metal powder sourced from used drinking cans with varying aluminum masses of 3, 4, 5 and 6 g with water and KOH catalysts of 2, 3 and 4 M in a fixed bed reactor, with a process for 20 minutes at a temperature of 50 °C. The results of the reactions were analyzed using a Gas Detector Analyzer. This study shows that 6 g of aluminum catalyzed with 4 M KOH results in 66% Hydrogen gas, and 3 g of aluminum catalyzed with 2 M KOH results in 20% Hydrogen gas. This proves that increasing the amount of mass and concentration in the process increases the resulting volume of hydrogen gas.

Abstract

Heavy metals are dangerous environmental pollutants known to produce toxic effects on various organ systems in humans and other living organisms. Lead (Pb) is one of the common heavy metals found as a contaminant in the environment, capable of causing a range of negative impacts. This experiment was conducted to analyze the ability of a composite made from TiO2 and activated carbon derived from durian peel to absorb Pb ions present in laboratory waste. Additionally, this experiment also focused on calculating the adsorption kinetics. The activated carbon, weighing 25 grams, was activated with KOH using various solvent concentrations of 2, 3, and 4 M. The activated carbon was then added to 100 ml of titanium dioxide solution, and the mixture was dripped into an STTP-ethanol solution. The sample was stirred for varying durations of 10, 20, 30, and 40 minutes. The sample was filtered and then analyzed using AAS. The optimal time found in this study was 40 minutes, with an adsorption efficiency of 95.45% and an adsorption capacity of 4.2000 mg/g. The adsorption of Pb metal followed the Langmuir isotherm model.

Abstract

Glycerol is a byproduct of the biodiesel transesterification reaction that has a low purity level, also known as crude glycerol. Approximately 10-20% by weight of glycerol is produced as a byproduct of each biodiesel transesterification reaction. Crude glycerol contains many impurities, which has led to its suboptimal management. To reduce waste generated from the biodiesel transesterification reaction, further purification is necessary to produce high-purity glycerol with significant market value that can be used in various industries. Therefore, researchers aim to utilize natural zeolite from Malang as an adsorbent in the purification of crude glycerol. This study is conducted to understand the impact of chemical and physical activation on Malang natural zeolite in enhancing its characteristics as an adsorbent and to determine the optimal conditions (residence time and adsorbent weight) for achieving the highest purity glycerol through the adsorption process. The natural zeolite from Malang was prepared by activation with H2SO4 and calcined with 3 hours at 500°C. This was followed by an adsorption method using an adsorption column with varying residence times (30, 45, 60, 75, and 90 minutes) and adsorbent weights (20g, 40g, and 60g). The chemical and physical activation of Malang natural zeolite successfully enhanced its adsorption capacity by increasing the active pore size (0.97 μm – 4.42 μm) and reducing impurity ions, as well as raising the Si/Al ratio to 4.503. The optimal glycerol purity achieved was 86.33% with adsorbent weight of 60 grams and a residence time of 60 minutes.
