Abstract: One of the major sources of water pollution is oil spills or oily waste waters and removing this pollution is a global concern. Nowadays natural sorbents are applied as single solution for oil spills since this technique is effective, rapid and cost saving for cleaning these pollutions and reduce environmental effects. Adsorption is promising choice of treatment for its simplicity, effectiveness, and feasibility when appropriate sorbent is used. The used of bagasse as adsorbent especially when structural component of bagasse which is made up of carbon material is suitable as adsorbent and the fact that, adsorbent bagasse further reduce solid waste disposal and hence reducing one source of environmental pollution. In this paper, raw sugarcane bagasse and taro leaves in different particle sizes was used for the sorption of layer of crude oil from lubricating oil get from motorcycle workshop. Mineral fluid lubricants are based on mineral oils. Mineral oils (petroleum derived) are product of refining crude oil. There are three types of mineral oil such as paraffinic, naphtenic and aromatic. In this experiment, we are use paraffinic oil. Paraffinic oil are used for manufacturing engine oils, industrial lubricants and as processing oils in rubber, textile and paper industries. The adsorption process is on going, found that organic waste such as taro stem and sugarcane bagasse can adsorb lubricating oil waste quickly by using a reagent, N-BromoSuccinimide (NBS) as an additive for adsorption. The result showed that máximum adsorption capacity of raw sugarcane bagasse for dry system was about 40% to 50% and for taro stem was about 30% to 45% depends on their mass, size and time taken. In this study, it can be concluded that using taro stem and sugarcane bagasse with NBS probably can remove the oily layer in drainage system.
