Abstract

PT. LIL is one of the companies engaged in the business of managing palm oil into Crude Palm Oil (CPO) and palm kernel oil or Palm Kernel Oil (PKO). The method used in this research is the Simplex Method which is one of the methods in the Linear Program that helps in solving a problem with more than two variables. The purpose of this study is to determine the optimal profit, type and number of products to be produced and to determine the value of sensitivity to the optimum solution achieved. Based on the results of research conducted, it can be concluded that the optimal benefits obtained by PT. LIL is Rp. 11,038.7 per kg by producing Crude Palm Oil (CPO) as much as 1.0776 kg and kernels as much as 0.9224 kg. If there is a change in the objective function coefficient for the base variable, the gain for the CPO and kernel remains optimal if it is greater than 0. If there is a change in the right side of the boundary, an optimal percentage ofcontent is oil loss CPO1.45% and kernel is 0.24%, moisture CPO 0.25% and 6.36% kernel, dirty 0.05% CPO and 6.7% kernel and FFA (Free Fatty Acid) CPO content 0%.

Abstract

In Indonesia there are many companies that are engaged in tire retreading or reuse of unused used tires. One of the problems in the retread business in Indonesia is that the tire production target is often not fulfilled and the lack of available tires is used as the main raw material for retreading due to the long process of sending tires from consumers to companies. The purpose of this study is to determine the optimal needs of resources, determine the priority of achievement and determine the value of sensitivity to the optimum solution achieved. The method used in this study is the Goal Programming Method, because it is suitable for problems that have many goals because through its deviation, the method can automatically capture information about the relative achievement of the goals to be achieved. Based on the results of research that has been done, it can be concluded that the maximum income earned by the company is IDR 474,426,000 or an increase of 36% from the limit set by the company. In addition, it can also be concluded that the sensitivity range for the boundary quantity value is the distance at which the shadow price remains valid. If it increases above the upper limit of sensitivity (increases) or decreases below the lower limit (decreases), the value of the shadow price will change.
