The increase in the number of washing industries each year parallels the increase in waste production. Without previous treatment, the created laundry waste will be disposed of straight into the environment, causing environmental damage. Laundry waste is characterized by high concentrations of BOD, COD, and LAS, which contribute to environmental damage. This study's objective is to treat laundry waste by adsorption using shell waste. Observed variables included powder size (50, 100, 150, and 200 mesh) and contact time (30, 60, 90 and 120 minutes). The filtrate was tested to determine the concentrations of BOD, COD, and LAS. The obtained results indicate that the optimal adsorbent size is 150 mesh, which can lower BOD levels by 80%, LAS levels by 38.85%, and COD levels by 67.34 %. The optimal period for decreasing COD and BOD levels is 90 minutes, which can reduce BOD levels by 80 percent and COD levels by 74.5 percent, and 120 minutes, which can cut LAS levels by 35.67 percent. The appropriate LAS adsorption isotherm is the Freundlich isotherm with R2 of 0.95023. The use of eggshell waste as an adsorbent demonstrates the significance of environmentally friendly waste treatment technology to laundry waste treatment.

Aluminum Alloy 5052 (AA 5052) is a metal that can be used as a biopolar plate in proton exchange membrane fuel cell (PEMFC), because it has the advantages of being resistant to corrosion, high conductivity, easy shape and light weight. PEMFC produces electrical energy and the rest of the process in the form of hot water and steam. In a bipolar plate PEMFC environment corrosion can easily occur due to an acidic environment and high operating temperature around 40°C-80°C. For this reason, a treatment is needed to strengthen the corrosion-resistant properties of AA 5052. The coating of the material can be done using the technique of electrophoretic deposition (EPD) using green inhibitor to reduce the corrosion rate. The electrochemical method was carried out to see how much influence temperature had on the corrosion rate of AA 5052. In this study, d-galactose green inhibitor with a concentration of 0.5 g, EPD time of 20 minutes was used, in a PEMFC environmental simulation in 0.5 M H2SO4 sulfuric acid medium, with test temperatures of 25°C (room temperature), 40°C, 60°C, and 80°C. From the results of the analysis using the electrochemical method, there was an effect of temperature on the corrosion rate of AA 5052 without an inhibitor layer of 0.3610 mmpy at room temperature and increased at 80°C 3.9527 mmpy. While AA 5052 which was coated with a d-galactose inhibitor, had a corrosion rate of 0.1678 mmpy at room temperature and continued to increase at a temperature of 80°C 3.7745 mmpy. Inhibitor efficiency was 53.51% at room temperature and decreased with increasing temperature to 4.5% at 80°C.
