Personal Care and Cosmetic Products (PCCPs) as a mixture of chemical compounds used in various hair, nail, body, and dental care products, among others, are utilized to enhance appearance and have become a necessity for people from various backgrounds. One commonly found and almost always used product is bath soap. Bath soap is significantly used in people's lives and also becomes a source of wastewater generated from this activity. Bath soap functions as an exfoliant and minimizes skin damage and irritation using microplastics and microbeads in its cleansing activity, resulting in the release of microplastics into water bodies from this activity. These microplastic pollutants endanger aquatic animal health and degrade water quality, potentially having broader environmental impacts. According to previous research, conventional methods are insufficient to effectively treat these pollutants, creating an urgent need for effective and low-cost wastewater treatment technologies to adequately treat PCCPs. Additionally, research indicates that the mass and contact time of adsorbents influence removal efficiency in studies involving other types of adsorbents, prompting this study to experiment with treating microplastics and other pollutants in PCCP wastewater. This study aims to determine the adsorption effectiveness using activated carbon as a treatment method for wastewater resulting from the use of Personal Care Cosmetic Products (PCCPs) for body care, and to identify the optimal time and mass of activated carbon adsorbent for treating wastewater from PCCPs. The study uses secondary data related to the body care products being studied and primary data from laboratory tests characterizing pollutants and microplastics in wastewater before and after adsorption treatment. Adsorption is carried out using variations in adsorbent mass (5, 10, 15 grams) and optimal adsorbent contact time (30, 60, 90, 120 minutes). Based on the research, the optimal mass of activated carbon adsorbent is 5 grams, with an optimal contact time of 90 minutes. Using optimal conditions, the activated carbon adsorbent for pollutants and microplastics in wastewater results in removal efficiencies for pollutants in PCCP wastewater from bath soap as follows: Total P 22.4%; Orthophosphate 51.65%; Ammonia 81.28%; Total Nitrogen 92.4%; COD 95.97%; BOD 27.25%; TSS -36.76%; TDS - 19.52%; Microplastics 62.6%.
