Electrical energy is one of the essential energies for the world due to the fast growth of the world population and houses. In Indonesia, 95 % of the energy used in the household in 2017 is electrical energy. Therefore, reducing the use of electricity in the household is crucial. In the past decades, customers have carried out several approaches to reduce the use of their electricity. One of the widely used methodologies is the EMS. However, the PDCA model has not been implemented in electricity consumption. Subsequently, this study applies such an approach focusing more on the planning stage and is implemented in Ternate City, North Maluku, Indonesia. The C4.5 algorithm is applied at the planning stage to form a rule in predicting household electricity consumption. Moreover, the system performance is tested using the confusion matrix. The data of electricity consumption is collected and the data is treated with a varying amount depending on the number of the training data applied. The results of the system performance test by applying the confusion matrix are 76.22, 90.3, and 74.4 % for the highest accuracy value, precision, recall, respectively with the number of rules formed by 14. HIGHLIGHTS The need for electrical energy in Indonesia continues to increase, especially the use of household electricity To reduce the consumption of electrical energy, a plan-do-check-act model is used. The research focuses on the plan stage by applying the C4.5 algorithm The highest system accuracy is 73.33 % with 14 rules formed GRAPHICAL ABSTRACT
