ALTERNATIVE UTILIZATION OF TOBACCO LEAF WASTE USING THE ANP METHOD AT THE REDRIYING BOJONEGORO COOPERATIVE

Abstract

The Bojonegoro Redriying Employee Cooperative (Kareb) is one of the tobacco drying places/services in East Java under the auspices of the cooperative. The tobacco sticks (ste,) operated by KAREB are not grown and piled up in the storage warehouse. Each tobacco drying process in 1 year produces 8,665,409 stems, while there is no additional cost for stem storage. This research uses the ANP method because there are 3 alternatives chosen in this research, namely briquettes, compost and bioplastics. ANP is a structured problem-solving method and there is a dependence on the relationship between its elements, the ANP method was chosen because the proposals to be applied have interrelated criteria, ANP involves hierarchical relationships but does not require a standard structure. The priority of each cluster in the model is in the 3 alternatives, namely briquettes with a value of 0.73868, then from the 6 sub-criteria, the highest value is in waste utilization, which is 0.66140, then from the 3 highest value criteria, namely the economic aspect with a value of 0.68261. Charcoal briquettes can function as an alternative fuel to replace the use of oil and gas fuel in industry and households, these briquettes are a source of renewable energy produced from biomass, namely plants or plants that are abundant in the environment. The ecological aspect because seeing the opportunity for waste if processed can be useful into a product with high selling value, from an economic point of view, the community's ability to process agricultural waste into charcoal briquettes as a source of renewable energy can be an additional source of income. The briquette production is the first step of authoring all biomass is put into a jobong container and burned, then the charcoal powder filled in the jobong is stretched and separated between charcoal and dirt, followed by the addition of adhesive and printer adhesive material used is tapioca flour.
