Abstrak

Penelitian ini bertujuan untuk memanfaatkan limbah pabrik CPO menjadi arang aktif sebagai adsorben metilen biru. Eksperimen diawali dengan proses karbonisasi dan dilanjutkan aktivasi arang aktif secara fisika (AAF) dan kimia (AAK). Arang aktif hasil aktivasi dikarakterisasi dengan Scanning Electron Microscope (SEM) untuk mengetahui morfologi permukaan, spektrofotometri IR untuk mengetahui gugus fungsi, dan analisis luas permukaan menggunakan alat penganalisis luas permukaan dengan metode BET (Brunaeur-Emmet-Teller) untuk menghitung luas permukaan. Uji adsorpsi arang aktif terhadap metilen biru dilakukan dengan metode batch, meliputi penentuan pH, waktu kontak dan konsentrasi optimum. Adsorpsi metilen biru pada AAF, AAK optimum pada pH 11 dengan waktu kontak masing-masing 60 dan 90 menit.. Isoterm adsorpsi metilen biru AAK dan AAF cenderung mengikuti model isoterm Freundlich (interaksi fisika) dengan R2 = 0,999, dengan kapasitas adsorpsi masing-masing ion sebesar 20,620 ; 22,424 mg/g. Kata Kunci : CPO, arang aktif, metilen biru, kapasitas adsorpsi abstract This research studies purposed is to made the utilization of CPO (Crude Palm Oil) from the industrial factory waste into an activated charcoal as an adsorbent of blue methylene. The experiment was started with the carbonization and continued with activating of the charcoal by physically and chemically. The activated charcoal which resulted from the activating process was characterized by Scanning Electron Microscope (SEM) to determine the surface morphology, spectrophotometric IR was used to knowed about its functional groups, and the surjace area analytion tool with BET methode. The adsorption tests of the activated charcoal in adsorbing blue methylene were performed by the batch method including the determination of a pH, contact time and optimum concentration. The blue methylene adsorption on the physically and chemically activated charcoal is optimum value at a pH 11 with a contact time of 60 and 90 minutes. The blue methylene adsorption on the physically and chemically activated charcoal isotherm leads to followed Freundlich’s isotherm model (physical interaction) with R2 value = 0,999 and the adsorption capacity of each other ion was 20,620 ; 22.425 mg/g Key word: CPO, activated charcoal, blue methylene, adsorption capacity
