T The industrial development in Indonesia has developed well recently. The effect of the development are good sides and bad sides. The good sides of the development is social welfare increasing of the Indonesian people, the bad sides of the development is environmental pollution. One of the industrial that developed well is Automotive industrial (car assembly) which produce wastes in solids, liquid and gases. Generally, automotive industrial wastewater consists of heavy metals that is very dangerous such as, Nickel (Ni), Chromium (Cr), Zinc (Zn), Lead (Pb), Cadmium (Cd) and Cooper (Cu). Those heavy metals is very dangerous for creatures because of it’s persistential in the environment and it’s bioaccumulation ability in aquatic organism. The concentration of ex-battery solidwastes is increasing year to year. The batteries has produced in Indonesia is almost approximately three billion per year which the production capacity is 15 percent by domestic and 85 percent by nondomestic. Based on that total production the wastes zinc carbon batteries can reach 30 percen. With the battery average weight is 50 grams, so the ex-baaery solid wastes in Indonesia is going to be dump will reach 6,750 ton per year. The ex-battery solidwastes was classified into a dangerous ones, cause it contains dangerous’metals such as Mercury, Cadmium, Manganese, and Chromium, where the metals can be a small pollutant that is very dangerous although they have minimum concentration in environment. Cause of that reason to do the experiments to reuse ex-battery solidwastes become a new media that can be used in sorption process of activated carbon removing the heavy metals in automotive industrial wastewater.Adsorpsion is a process of the molecules gathering from external and internal part to the surface of solids cause of the power of the atoms on the surface of activated carbon. There are two ways of adsorption process, they are physics and chemist. Adsorption isotherm which generally used is Freundlich isotherm and Langmuir isothemi. The activated carbon, based on its form, classified into powdered and granular. Based on the type, classified into the gas sorption and the liquid sorption. Based on its pores distribution, classified into macropores, trantitionpores and micropores.Based on the research, it can be found out that the metals concentration of Zn, Ni and Pb is over the naximum concentration has been decided by government by Keputusan Gubemur DKI Jakarta No.582 Tahun 1995. More the volume and the concentration of the activation liquid, it makes the sorption of activated carbon will get higher. The powdered activated carbon from ex-battery solidwastes is more effective than the granular ones. The NaOH activation is more effective than the HCI activation. The activated carbon from ex-battery solidwastes is most effective to remove the metals especially Zinc (Zn) with removal efficiency almost 98 percent for the powdered activated carbon. The average removal efficiency for Nickel (Ni) almost 30 percent and it is same for Lead(Pb).
