Chokato is name of a cocoa processing plant in Payakumbuh, West Sumatra. It is a small scale industry that produced some kinds of processed cocoa products. Although the plant has been in production more than two years, but have not been able to achieved the maximum capacity and unknown amount of each type of product that could be reach the optimal profit. This research aimed to determined the optimal production quantity of each product to maximized the total profit, to found out maximum level of production capacity and its utilization level. The method used to was Linear Programming (LP) There were eight scenario models that tested with various production target for each product.The computation was done by Lingo 10.0 where the results indicated six models produced a feasible solution. Next, the model solutions must be adjusted due to some products were interdependent namely pure powder, 3in1 powder, and butter. Model-1 gives a maximum profit of Rp. 23.982.375 per month by producing pure powder 110,5 kgs, butter 59,5 kgs, candy-chocolate 7,6 kgs and scrubs 268,1 kgs. Total maximum capacity of plant that could be reached at optimal profit was 445,7 kg per month. On average models indicated that utilization level of two machines were above 80% and 10 machines were below 10%. Production capacity of the plant could be increased by improving capacity of machines that have high utilization level.
