Refining process in Palm Oil Industry produced Spent Bleaching Earth (SBE) as a by products, this waste is included in the category 2 Hazardous Waste(B3) waste group with an oil content 20-30%. This oil content is feared to have easy potential to flammable. One of methods that used to reduce this oil content is solvent extraction with N-Hexane in accordance with DeOBE as a results around + 3% of the SBE volume, then DeOBE provides an alternative treatment like solidification and reactivation. This SBE waste has economic potential based from the entry of SBE in the category of vegetable oil, oil and fat with HS code 84792 export commodities. The current condition of SBE management is carried out in the simplest way by providing SBE waste to third parties that have landfilling B3 waste permits, thus the B3 waste management business has not been carried out much. Scenarios are arranged to see optimal alternatives in SBE waste management consisting of extraction, solifidication, reuse, and stockpiling on 3rd parties, the methods that used in this decision making is Process Network Analysis (ANP) this method is widely used In complex problems with several criteria, (using multicriteria) by using experts as respondent respondents. The criteria included in this analysis are Environment, Technical, Economic and Institutional, from which the agreed criteria will be elaborated with several subcriteria which are also made as control elements. Responding to represent representatives who have links with the SBE directly or indirectly from private groups, sending, academics, and the government. ANP is denied by Super Decision Power version 2.8 so that the optimum value in scenario 2 is extracted and Solidified - Financing to third parties (50:50), besides that according to the dominant criteria is environment (0.5311) and safety (0.2559 ) Dependence-Driving Power Analysis (DDPA) also combines to see the nature of the sub-criteria in each criterion so that the resulting subcategory dominant depends on the clusters of linkages with strong dependency and driving power and 3 subcriteria in the independent cluster with weak dependency values and driving power the strong one.
