Industrial development in Indonesia may adversely affect such environmental pollution. Among the various industries, electroplating industry has an important role because it produces small volumes of waste but highly toxic for environment due to the presence of heavy metal such as Cr (VI) and Cu (II). Biosorption can be the best alternative technologies in the heavy metal adsorption. Mahogany (Swietenia mahagoni) is widely available in Indonesia and thrives in Java. Mahogany has been used for many purposes but mahogany fruit shell is unemployed. One of method to increase the economic value of mahogany fruit shell is structured as biosorbent to remove metal ion. Biosorbent used in this study consists of three types of process: biosorbent without treatment (BWT), biosorbent treatment condensation polymerization (BTCP), and biosorbent treatment immobilization with silica gel (BTSG). Size of the biosorbent, biosorbent dose, contact time, and initial concentration are known to have effect on heavy metals absorption efficiency. Type of biosorbent with the best performance for real industrial apllication in sequence is BTSG, BTCP, and BWT with adsorption efficiency respectively 94%, 92%, and 46%. For industrial applications biosorben types of BWT is considered the most economically viable.
