Kemampuan Adsorpsi Arang Tandan Kosong Kelapa Sawit (Elaeis Guineensis Jacq.) Teraktivasi Zncl2 Sebagai Adsorben Escherichia Coli Dalam Larutan

---

Oil palm empty fruit bunch charcoal (Elaeis guineensis Jacq.) is a potential raw material that can be utilized as an adsorbent for Escherichia coli (E. coli). The cellulose content in the empty fruit bunch charcoal acts as a carbon source in the
E. coli adsorption process, whose efficiency can be enhanced through an activation process using ZnCl₂ as an activating agent. The addition of ZnCl2 activator can open pores on the adsorbent surface. This study aims to investigate the adsorption capability of ZnCl₂-activated empty fruit bunch charcoal in removing E. coli. Batch adsorption method was used in this study with variation of adsorbent dose (0.25; 0.50; 1.00; 1.50; and 2.00 g) and variation of contact time (60, 90, 120, and 150 minutes). The charcoal was produced through carbonization at 300°C for 120 minutes, then ground and sieved to obtain particles passing through a 50 < x < 100 mesh sieve. The charcoal was then activated using zinc chloride (ZnCl₂) at a concentration of 1.5 M. The activated empty fruit bunch charcoal was characterized according to SNI 06-3730-1995 through methylene blue adsorption testing. Surface area, pore volume, and pore radius were analyzed using a Surface Area Analyzer with the BET method. Surface morphology was examined using SEM instrument. Measurement of the number of E. coli cells was carried out based on the turbidimetric method which is expressed in Optical Density (OD) using a UV-Vis Spectrophotometer. The characterization results showed that the methylene blue adsorption capacity of the activated charcoal was 1.7014 mg/g. Based on the BET analysis, the surface area of the activated charcoal was 0.391 m²/g, with a pore radius of 2.0303 nm and a pore volume of 0.001 cc/g. The best E. coli adsorption conditions were obtained at an adsorbent dose of 1.00 g and a contact time of 60 minutes with an average adsorbed E. coli cell count of 3.40 × 108 cells/mL or an
E. coli adsorption efficiency of 60.66%.
