ABSTRACT
Test of activated carbon adsorption ability of banana stem waste
(Musa paradisiaca L) on toluen has been carried out. Scanning Electron
Microscopy (SEM) was used to characterize activated carbon to show the
morphological differences in activated carbon after activation and before
toluen adsorption using a UV spectrophotometer with variations in the
time of adsorption and concentration. The optimum toluen adsorption time
obtained on the adsorbent weight of 0.4 gram, the concentration of toluene 40 ppm was 45 minutes, then the absorbed toluene concentration was 61,75%. the adsorption capacity was 1,5438 mg/L and the optimum toluene concentration at 1 grams, 60 minutes adsorption time was 40 ppm. The concentration of toluene absorbed was 73,875%. Then the adsorption capacity was 0.07388 mg/L.

ABSTRAK
Uji kemampuan adsorpsi karbon aktif dari limbah batang pisang
(Musa paradisiaca L) terhadap toluen telah dilakukan. Pada karakterisasi
karbon aktif digunakan alat Scanning Electron Microscopy (SEM) untuk
menunjukkan adanya perbedaan morfologi karbon aktif setelah diaktivasi dan
sebelum diaktivasi sedangkan adsorpsi toluen menggunakan alat
spektrofotometer UV dengan variasi waktu adsorpsi dan konsentrasi.
Didapatkan waktu adsorpsi toluen optimum pada berat adsorben 0,4 gram,
konsentrasi toluen 40 ppm adalah 45 menit maka konsentrasi toluen yang terserap sebesar 61,75% dengan kapasitas adsorpsi sebesar 1,5438 mg/L dan konsentrasi toluen optimum pada 1 gram, waktu adsorpsi 60 menit konsentrasi 40 ppm, konsentrasi toluen yang terserap sebesar 73,875% dengan kapsitas adsorpsi sebesar 0,7388 mg/L.
