Adsorpsi Methylene Blue Oleh Arang Kayu Bakau (Rhizophora Mucronata) Diaktivasi Dengan Larutan Pemutih

---

ABSTRACT
The rapid development of industry has contributed greatly to economic growth, but has also had a negative impact on the environment, especially in the form of water pollution due to industrial wastewater. One of the common pollutants is methylene blue dye, which is widely used in the textile industry. This substance is toxic, difficult to degrade, and can cause disruption to aquatic ecosystems and health impacts such as irritation, genetic mutations, and reproductive disorders. Therefore, an effective wastewater treatment method is needed, one of which is through the adsorption process using natural adsorbents. This study aims to examine the potential of activated mangrove charcoal (Rhizophora mucronata) as an adsorbent in the adsorption process of methylene blue dye and to determine the maximum conditions for the resulting adsorption capacity. Mangrove charcoal was activated using bleach solution (Proclin) for 24 hours, with particle size passing through 20 mesh sieve. The results of the test of the characteristics of activated mangrove charcoal and non-activated mangrove charcoal were in accordance with the provisions of SNI with the activated charcoal value having a water content of 5.16% and an ash content of 2.14%. While charcoal without activation had a water content of 5.87% and an ash content of 4.00%. The adsorption process was carried out with variations in adsorbent mass of 1.0; 1.5; and 2.0 grams, and a contact time of 1 to 5 hours. The results showed that the maximum adsorption capacity of activated charcoal was achieved at 0.364 mg/g, at an adsorbent mass of 1 gram and a contact time of 2 hours. This study shows the potential of activated mangrove charcoal as an alternative adsorbent in handling liquid waste containing methylene blue dye.
