Coconut shell is one of the abundant agricultural solid wastes in Aceh Province. Meanwhile, a solid waste of coal fly ash is a by-product from PLTU Nagan Raya. Both coconut shell and coal fly ash have a great potential to be utilized as adsorbent. The aim of study is to prepare and characterize the adsorbent made from combination of coconut shell activated charcoal and coal fly ash. The prepared adsorbent was characterized using Scanning Electron Microscopy (SEM) to study the morphological structure, Fourier Transform Infra-Red Spectrophotometer (FTIR) to detect the functional group and X-Ray Diffraction (XRD) to determine the crystalline structure. Performance of adsorbent was carried out by adsorption process of methylene blue solution on adsorbent. The characterization results showed that all four types of the prepared adsorbents met the requirements of water content quality and iodine adsorption according to SNI 06-3730-1995 concerning to activated charcoal. It was obtained that adsorbent with the best performance was coconut shell activated charcoal (without addition coal fly ash) having the adsorption capacity to methylene blue of 45.36 mg/g on adsorption contact time of 140 minutes.
