Abstract

Tofu wastewater effluent contained high value of BOD, COD, and suspended solids which needed treatment before disposed to environment. The research aims to study the adsorption of BOD and COD in tofu wastewater using chemically impregnated carbon derived from coffee husks (Coffea Arabica L.). The Arabica coffee husk carbon (ACHC) activated with ZnCl2 0.1 N and CaCl2 0.1N for 3 hours. Carbon characterization compared with Indonesian standard of SNI No.06-3730-1995, and the surface area was examined by Fourier transform infrared spectroscopy (FTIR). The results showed that the moisture and ash content characteristics has met the Indonesian standard, but the iodine adsorption capacity was decreased with longer activation time. The highest iodine adsorption recorded at 888.37 mg/gr adsorbent using ZnCl2 0.1 N at 1 h activated time. The BOD and COD removal efficiency were 88% and 25%, for ACHC with ZnCl2 0.1N; Meanwhile carbon with CaCl2 0.1N has a removal efficiency 66% and 24% for BOD and COD, respectively. In conclusion, the variation of chemical activators and the longer contacted time gave significant effect on the removal of pH, BOD and COD from tofu wastewater. To obtain optimum COD adsorption efficiency in wastewater treatment, other factors such as the impregnation ratio, the activators concentration, the mixing time, and its combination method were needed further investigation.

Abstract

The development of lithium batteries is one type of research that continues to be developed. Recently, lithium batteries have become the most widely used source of electrical energy as raw materials for the manufacture of lithium batteries. This study aims to compare the synthesis with Co precipitation and sol-gel methods as electrodes in lithium batteries. Nanosized particles were characterized for characterization using (X-ray fluorescence (XRF) and scanning electron microscopy-energy dispersive X-ray (XRD) and (SEM) -EDS). Based on the XRF characterization test, the results showed that the chemical composition of Magnetite Fe3O4 contained in the iron sands of the Syiah Kuala beach showed material purities of 87.10%, 86.73%, and 81.42% (Magnetite Separation). This shows that the synthesis of Fe3O4 using the sol-gel method yields results with better material purity than the coprecipitation method. The results of the SEM-EDS characterization test observations were based on particle analysis and the distribution observed on the surface morphology of the particles, where the sol-gel method provided precise results for the synthesis of Fe3O4 magnetite nanoparticles. The results of the characterization test based on the EDS analysis based on the EDS test obtained the amount of Fe3O4 of 70.00%, this indicates that the composition of iron provides a high value compared to other components contained in it

Measurement of river water quality due to pollution. The Alas Singkil watershed covers eight rivers in Subulussalam City which combine to form rivers. The purpose of the study was to analyze the level of water pollution of the Alas-Singkil River Basin (WS) with the test parameters of Total suspended Solid (TSS), pH, oxygen content and metal content. The results showed that the temperature of the Alas Singkil watershed showed a range between 27.4 – 29.1 °C. Temperature can affect photosynthesis in the Alas Singkil river area either directly or indirectly. The TDS test results showed a value of 23.9 mg/L - 97.5 mg/L which was still below the quality standard. The highest location for TDS is at the point of the Lae Kombih River (AP2) and the lowest value is at the location of the Lae Soraya River (AP1). The test results show that the value is still below the quality standard of 1000 mg/L. TSS test results between 4 -36 mg/L. The concentration of TSS in all locations does not exceed the quality standard set by the Government of Indonesia Regulation No. 22 of 2021 concerning the Implementation of Environmental Protection and Management for Water Class II. The pH test results are more stable and are in a narrow range of 6.82-8.86 pH because it is influenced by the buffer capacity, namely the presence of river flow sedimentation. The test results for the levels of metals: copper (CU), Lead (Pb), Cadmium (Cd) and Zinc (Zn) in the Alas Singkil Watershed (DAS) showed that they were still within the threshold with the Laboratory test results below the quality standard, namely 0, 0008 b , 0.0001 b , 0.0004 b and 0.0001 b (Not detected because it is below the Minimum Detection Limit for Test Equipment).Keywords: Surface water, watershed, quality, river water pollution, monitoring and control.

Abstract

This study aims to evaluate the effectiveness of phytoremediation using plants in reducing chromium (Cr) levels and modifying pH in batik wastewater. The research was conducted using three experimental tanks: Control Tank (without plants), Tank 1 (with 8 plants) and Tank 2 (with 16 plants). The results showed that in the control tank the pH fluctuated and reached 8.1 on the 9th day, while in tank 1 and tank 2 the pH was more controlled with peak values of 7.9 and 8.2 respectively. The most significant reduction in chromium levels occurred in tank 2, with treatment efficacy reaching 70% on day 9, compared to 45% in tank 1 and 10.5% in the control tank. These results indicate that phytoremediation with more plants can significantly improve the treatment efficiency of batik wastewater, making it a potential and environmentally friendly method for industrial wastewater treatment. The phytoremediation method was carried out by observing variations in the number of plants using 3 reactor tanks. The first tank was a control tank, the second tank (BR2) contained 8 plants and the third tank (BR3) contained 16 plants. Samples were taken on days 3, 6 and 9. The results showed that the highest effectiveness in reducing total chromium (Cr) levels occurred in the third tank (BR3) on day 9, with a reduction of 70%.
