Abstract

Groundwater often contains iron (Fe), which can cause a metallic taste, yellow color, iron bacteria growth, and turbidity. One method used to reduce iron content in water is the use of activated carbon. However, activated carbon has disadvantages such as long separation times and requires filtration equipment that can filter activated carbon. This study aims to produce magnetic activated carbon from cassava peel composite with magnetite to be used in reducing iron concentration in water. The methods used in this study included carbonization, activation with 2.5% KOH activator, activated carbon and magnetite composite with a 2:1 ratio, FTIR analysis, quality analysis through water content, ash, and iodine adsorption capacity tests in accordance with SNI 06-3730-1995 standards, surface area analysis using a BET instrument, and Fe adsorption application with varying times. The results showed that magnetite activated carbon was successfully synthesized, as confirmed by FTIR analysis, which indicated the presence of Fe-O bonds in the activated carbon and its ability to be attracted to a magnetic field. The adsorption effectiveness of magnetic activated carbon reached 77.38% with a contact time of 30 minutes. The quality test results of magnetic activated carbon did not meet the SNI 06-3730-1995 standard, with an iodine adsorption capacity of 620 mg/g. This study provides an overview of magnetic activated carbon composites  from cassava peel, which have advantages in the separation process between adsorbent and adsorbate after adsorption. Research on the optimization of the manufacturing process for magnetic activated carbon that meets SNI standards is urgently needed.

Abstract

This study aimed to formulate a room freshener gel from seaweed (Eucheuma sp) with variations in acetic acid soaking concentrations (0%, 5%, and 10%) and to evaluate its physical characteristics. The seaweed-based gel was produced through soaking, heating, and molding processes combined with gelatin, isopropyl alcohol, and essential oils (lemon, sweet orange, and lily). Quality testing covered moisture content, viscosity, gel strength, and organoleptic properties. Results showed that the soaking treatment significantly affected gel quality. The unsoaked sample had the highest moisture content (24.08%), exceeding the SNI limit of 23.22%, while the 5% and 10% soaking treatments met the standard with moisture contents of 17.43% and 19.64%, respectively. Viscosity values ranged from 62,237 to 73,111 μm/pascal, all within the ideal range for semi-solid gels. Gel strength values of 85.859, 291.45, and 615.77 g/cm² for the three treatments all exceeded the minimum standard of ≥45 g/cm². Organoleptic evaluation by 20 panelists showed that the 5% acetic acid soaking treatment produced the best scores for aroma (3.70) and texture (4.25), meeting the SNI 01-2346-2006 acceptance threshold. This treatment is recommended as the optimal formulation for seaweed-based room freshener gel.
