Judul	:	PEMANFAATAN BIOMASSA KULIT BATANG JAMBU BIJI (Psidium guajava L.) UNTUK ADSORPSI LOGAM BES
Abstrak	:	Guava’s bark contains tannin compound that can be used as an adsorbent. The purpose of this study was to determine the optimum conditions of the adsorption of iron bythe bark and its maximum absorption capacity. The study was conducted by mass variation of bark for iron metal adsorption. The measurement of iron concentration which was not absorbed by the bark was conducted by Atomic Absorption Spectrophotometer. The results showed that the adsorbentm as sof 2.5 grams can  absorb1.93mg/g with percent absorbance of 48.34%, and the maximum absorption capacity of iron  lost at 4.98mg/g.
