This research is aimed to decrease of sulfur level from jengkol bean by giving some treatments. This research used eksplorative design with 4 treatments and 3 replications. Treatments were consist of boiling jengkol in ash solution, boiling jengkol in whiting solution, boiling jengkol in water and aging jengkol in soil. Result of this research obtained that differences of treatments on jengkol resulting different effect toward water content, ash content, sulfur content and pH. The most drastic decrease of sulfur is to use whiting and followed by the use of kitchen ash, boiling in water and aging in the soil. Keywords: Jengkol bean, Some treatment and Sulfur
