Abstract

Pengolahan air limbah dari bengkel kendaraan bermotor merupakan tantangan lingkungan yang signifikan karena tingginya kandungan bahan organik, termasuk Total Organic Carbon (TOC). Salah satu solusi yang inovatif dan efisien adalah penggunaan metode elektrokoagulasi. Penelitian ini bertujuan untuk mendesain alat elektrokoagulasi yang portabel dan menentukan waktu yang efisien untuk penurunan parameter TOC. Dalam penelitian ini, elektroda aluminium digunakan untuk menginduksi reaksi elektrokimia, menghasilkan ion logam yang mampu mengadsorpsi dan mengendapkan kontaminan dalam air limbah bengkel.Eksperimen dilakukan dengan variasi waktu proses elektrokoagulasi, yaitu 3 jam dan 5 jam, untuk mengukur efisiensi penurunan TOC. Hasil uji laboratorium menunjukkan bahwa proses elektrokoagulasi selama 3 jam berhasil menurunkan kadar TOC sebesar 55,7%, sementara proses selama 5 jam mencapai efisiensi 86,4%. Proses ini efektif dalam mencapai standar baku mutu yang ditetapkan untuk TOC, yaitu 110 ppm.Keunggulan elektrokoagulasi terletak pada efisiensi yang tinggi, biaya operasi yang lebih rendah, serta tidak memerlukan penambahan bahan kimia, sehingga menjadi solusi yang potensial untuk pengolahan air limbah dari bengkel. Penelitian ini memberikan kontribusi dalam bentuk desain inovatif yang dapat diaplikasikan pada skala kecil, khususnya bagi bengkel kendaraan bermotor yang membutuhkan teknologi pengolahan air limbah yang efektif dan ekonomis.

Abstract

Some studies say the pollution level in the waters oil industry in Dumai City, Riau. The level of pollution that occurs will affect the abundance of macrozoobenthos. This research aims to know the concentration of oil and heavy metals in sediments in the waters around the area of the Dumai City oil industry, knowing the effect of oil on the abundance of macrozoobenthos. This research method includes placement of research stations, observation and sampling, TSS sample analysis method, concentration oil in sediment samples, heavy metal concentrations of Pb, Cd, and Cu at sediment samples, macrozoobenthos abundance Analysis, and data analysis. Results research average concentration of oil in sediments in water areas The oil industry of Dumai City, Riau, has passed the threshold that has been set determined by the Department of Water Resources Quality Assurance/Quality Control Program That is > 1000 ppm, so it can be said that station 1 up to 9 are polluted and harmful to organisms that live on the bottom those waters relationship of oil concentration, heavy metals (Pb, Cd, and Cu) moderate to weak.

Abstract

This research was conducted in March 2022 in the Coastal Waters of Dumai City. Thisstudy aims to analyze the amount of organic matter and the abundance of macrozoobenthosand the relationship between the amount of organic matter and the abundance ofmacrozoobenthos. The method used is a survey method consisting of 10 stations with 2replications at each station. And 1 station is a control station located on the north coast ofNorth Rupat District, Bengkalis Regency. Sediment sampling was carried out in the field andthen taken to the Marine Chemistry Laboratory, Riau University for analysis of organic matterand macrozoobenthos analysis. Based on a simple linear regression test, the relationshipbetween the amount of organic matter and the abundance of macrozoobenthos obtained acorrelation value (r) = -0. 4637 with the mathematical equation y = -4.884x + 98.896. The testresults show a weak and inverse relationship between the amount of organic matter and theabundance of macrozoobenthos. This means that with the increase in the amount of organicmatter, the abundance of macrozoobenthos in the coastal waters of Dumai City will decrease.The value of the coefficient of determination (R2) is 0.2146. This figure shows that the effectof organic matter on the abundance of macrozoobenthos is small, namely 21.46%.

Abstract

The treatment of wastewater from automotive workshops presents a significant environmental challenge due to the high levels of organic materials, including Total Organic Carbon (TOC). One innovative and efficient solution is the use of electrocoagulation methods. This study aims to design a portable electrocoagulation device and determine an efficient time for reducing TOC levels. In this research, aluminum electrodes are used to induce electrochemical reactions, generating metal ions that can adsorb and precipitate contaminants in workshop wastewater. Experiments were conducted with different electrocoagulation process durations, specifically 3 hours and 5 hours, to measure TOC reduction efficiency. Laboratory test results indicate that electrocoagulation for 3 hours reduced TOC levels by 55.7%, while the 5-hour process achieved an efficiency of 86.4%. This process effectively meets the standard quality threshold for TOC, which is 110 ppm. The advantages of electrocoagulation lie in its high efficiency, lower operational costs, and the absence of the need for additional chemicals, making it a promising solution for wastewater treatment in workshops. This research contributes through an innovative design that can be applied on a small scale, particularly for automotive workshops that need an effective and economical wastewater treatment technology. Keywords: Electrocoagulation, Efficiency, Workshop Wastewater Treatment, Total Organic Carbon (TOC
