Adsorption of methyl violet and methylene blue has been done on using bamboo leaf ash. This researchaims to study the characterization adsorbent by FT-IR spectrophotometry and adsorption with the parametersinteraction time and pH. The concentration of the dye was determined quantitively by UV-Visspectrophotometer. FT-IR spectogram of bamboo leaf ash show that typical fingerprint in IR spectrogram ofaf asdeobent with Si-O and Al-O groups. The adsorption results showed that optimum methyl violet adsorptionat 12 minutes and pH 11 with adsorption capacity of 22.8738 mg/g and adsorption of optimum methylene blueat contact time of 8 minutes and pH 11 with adsorption capacity of 17.9989 mg/g
