ANALISA FAKTOR PENINGKATAN KONSUMSI ENERGI DENGAN PENERAPAN THEORY OF CONSTRAINT DI PT SEMEN PADANG

Abstract

PT. Semen Padang is one of the manufacturing industry companies in Indonesia engaged in cement production. The high cost of energy consumption of PT semen Padang. Thus, pt Semen Padang products will be more difficult to compete in the market share, because the main price of production of PT Semen Padang by 50% is the cost for energy consumption. This research aims to identify, find the root cause of the problem and provide alternative solutions with the theory of constraint method. To find the cause of the high cost of energy consumption in PT Semen Padang and provide solutions to the problem. Initially in this method is to set the goal with intermediate objective tree which the goal is to lower the energy per ton of the product, after that enter into the current reality tree with output obtained 3 causes of problems namely policy buy spare parts cheaper, No improvement on leakage / false water, Wrong production policy. In evaporating cloud there are 3injections namely the manufacture of spare parts in workshop PT Semen Padang, making a leak schedule, producing at optimal capacity, after which in the future reality tree describes the occurrence of each injection in the future, then finally on the presquite tree describes the requirements for each action to be taken. Entry to the benefit cost ratio is obtained as a result that the injection that provides the greatest profit is produced at optimal capacity with BCR worth 8 with a benefit value of Rp. 663,019,000,000 and an investment value of Rp. 82,836,740,978, therefore the investment is worth doing because it is worth more than 1.
