Natural rubber latex waste usually throw away to be unused materials and caused environment issue. One of the ways to handle this environment issue by using natural rubber latex waste as oil adsorbent. Natural rubber latex waste also had oleophilic and hydrophobic properties that are suitable to being used as oil adsorbent. In this research, researchers found out adsorption capacity of natural rubber latex waste to oil and oil from water, also the characteristics of it’s adsorption with Langmuir and Freundlich isoterm adsorption model. The adsorption characteristics of lubricant oil from water with natural rubber latex waste more fitted well with Langmuir isotherm equation model and the maximum adsorption ability of lubricant oil from water with natural rubber latex waste also significantly increased with the contact time till reached the equilibrium. The results of this study concluded that natural rubber latex waste had a great adsorption capacity and suitabled for being used as oil adsorbent.

The use of waste of natural rubber latex with banana sheats powder filler to serve as a more useful product that is used as adsorbent of oil. The process begins with drying the adsorbent manufacture banana and polished up to 100 mesh size. Then the banana powder mixed with waste latex with variations of 10 and 20% (w / w). The analysis of the ability of the adsorbent adsorption isotherms using the Langmuir equation and Freundlich isotherm equation. Research carried out by the batch process and the use of lubricating oil as the adsorbate. The results obtained showed the addition of banana powder as filler waste adsorbent adsorption of latex increases the ability of the oil adsorbent. The conclusion of the analysis showed an increase in the number of characteristics adsroben banana powder can enhance the adsorption of adsorbent.
