EFFECT OF TIME VARIATION ON XYLENE USING ACTIVE CARBON FROM WASTE OF BANANA STEM (Musa paradisiaca L)

Test of activated carbon adsorption ability of banana stem waste (Musa paradisiaca L) on xylene has been carried out. In the characterization of activated carbon Scanning Electron Microscopy (SEM) was used to show the morphological differences in activated carbon after activation and before activation while xylene adsorption using a UV spectrophotometer with variations in the time of adsorption. The optimum xylene adsorption time was obtained on the weight of 0.4 gram adsorbent, the concentration of xylene 40 ppm was 45 minutes, the adsorption capacity was 1.772 mg/g.Uji kemampuan adsorpsi karbon aktif limbah batang pisang (Musa paradisiaca L) pada xylena telah dilakukan. Dalam karakterisasi karbon aktif Scanning Electron Microscopy (SEM) digunakan untuk menunjukkan perbedaan morfologi dalam karbon aktif setelah aktivasi dan sebelum aktivasi lalu adsorpsi xylena menggunakan spektrofotometer UV dengan variasi waktu adsorpsi. Waktu adsorpsi xilena optimum diperoleh pada berat adsorben 0,4 gram, konsentrasi xilena 40 ppm adalah 45 menit, kapasitas adsorpsi 1,772 mg / g
