Abstract

Indonesia's need for electrical energy is also increasing along with increasing industrial activity. One of the power generating units that plays a vital role in Indonesia is the PLTU. PT. Bhimasena Power Indonesia is a PLTU company located in Batang, Central Java. The main fuel for electrical energy in PLTUs is coal. The transportation is carried out using trucks. However, due to limited parking space and a long unloader system, there are queues for truck transportation. Manufacturing Cycle Effectiveness calculations were carried out to determine the effectiveness value of the unloader system and then elimination of non-value added activities was carried out. It was found that the effectiveness percentage which was previously 51.6% became 55.3% after elimination, it could optimize the effectiveness value of the ash loading system at PT Bhimasena Power Indonesia.. Keywords: PLTU, Manufacturing Cycle effectiveness, Unloader.

Abstract

Every customer or consumer has different wants and needs, but the way they behave to fulfill these needs remains the same, namely they want to maximize their satisfaction by purchasing the goods or services they need. By looking at consumer purchasing patterns, sellers can find out customer purchasing behavior patterns. This pattern can help sellers in developing sales strategies. The aim of this research is to analyze the purchasing patterns of Indomaret Student Army consumers by applying the Association Rule - Market Basket Analysis (AR-MBA) method. This shopping cart analysis helps find out how the goods or services purchased by customers relate to each other. The results obtained from the Rapidminer software show that there are 6 combinations of purchasing patterns from department 1 mineral water, department 4 snacks, department 11 bread, and department 23 biscuits.
