Evaluation study of electrical energy usage using prayer models on post payment for electric customers household

This study aims to find solutions for saving electricity consumption in households. This electricity consumption savings need to be done because it is seen from the supply side management, the availability and limitations of natural resources, especially for fossil materials that are widely used in power plants, are decreasing in number, not to mention the issue of potential CO2 emissions polluting the environment due to activities at this power station. Whereas seen from the demand side management, the savings in electricity consumption will reduce electricity expenditure for the consumer community, especially household customers. The method of research is carried out with a survey in the field. Respondents were divided into two groups, namely the experimental group from prepaid electricity customers and control groups from postpaid electricity customers. By applying the same load to the control group with the experimental group, then the level of accuracy is measured. Samples taken randomly. From the data generated in the analysis of whether there are significant differences in the experimental group can bring changes in electricity consumption in the control group. Furthermore, from the results of data analysis can be used to draw conclusions. This is where there will be benefits to be gained, namely a new concept of how to use electricity that is economical. and this concept is ready to be implemented in the community, through a community service program, which is certainly very useful for stakeholders and published through international seminars and made as a supplementary textbook for electrical power installation courses.
