Used lubricants are one of the hazardous waste which regulated in Government Regulations on the limits of lead contained, so it is necessary to do research in reducing the lead contained. The purpose of this study is to obtain the effect of adding adsorbents to reduce lead content on used lubricants, taken from ship waste. Then regenerated by adsorption using zeolite. 200 mL of used lubricant samples that have been physically and chemically identified in the adsorption process using an adsorbent concentration variable 7.5%; 13.25% ; 14.25%; 15.75%; 17.5% (b/b) with stirring speed of 150 rpm, and contact time for 60 minutes. In the research data, a regression test was performed and a regression equation was produced with y being the lead content and x number of zeoilt, y = 0.0077x2 - 0.371x + 6.3818, which the best results were obtained at the adsorbent number 26.5 grams (concentration 13.25 %), lead decline reached 83%. The ANOVA test results obtained F count value of 13.42, this value is greater than F Table for level of 0.05 is 4.92, it was concluded that there was a correlation between the concentration of the adsorbent and the decrease in lead content.
