Abstract
The amount of palm oil waste that has not been utilized optimally, such as Oil Palm Empty Bunches (OPEFB). OPEFB waste can be used as a raw material for partition boards to replace ceramics, by processing OPEFB into fibre and adding resin adhesive to the partition board moulding process. The process of making partition boards requires an economic analysis that is calculated from the cost of using raw materials, tools, labor, operational costs, and margins to get the value and selling price in the community. ceramic partition board with a size of 40 cm x 40 cm with a thickness of 5 mm where this size is adjusted to the ceramics used by the community. economic analysis is calculated from the capital for 1 month or 24 working days with the cost of raw materials Rp. 68,811,200, labor wages Rp. 7,200,000, Overhead Rp. 3,893,000, and the use of tools is Rp. 48,900,000 where the total cost of tools in 1 month of work is Rp. 815,000 whose use is calculated for 5 years of use, while the results are 6,912 pcs/month, from the capital price issued the price of the partition board is Rp. 84,000/box which in 1 box contains 6 pcs. The price of ceramic partition boards obtained is 84,000/box which is still stated as standard in sales with the selling price of ceramics in the community Rp. 55,000 - Rp. 120,000.
