Indonesia's strong economic growth is expected to continue, thus increasing electricity consumption to reach 491 Tera Watt hours (TWh) in 2030. Significant electricity savings can be obtained by increasing the electrical energy efficiency of homes. The aim of this study is to design a household electrical control system (KENDIL) by using the RLC circuit to reduce the flow in order to achieve more efficient home electricity distribution. The Data collection was carried out at Wisma Kertonegaran as a residential house consisting of 50 rooms. After using KENDIL, The PLN electricity bills per month was decreased from Rp. 176,601.82 / kwh to Rp. 107,294.85 / kwh. It can save electricity bill costs by 60%. This device is an application of electronic skills courses.

Physical experiments have a very important role in the development of science. Due to achieve that, it could be started by increasing the creativity of educators in innovating with the methods, models and learning media used. Research has been conducted with the aim of making a two phase phase inverter media to induce the human body and determine its input and output power. Method in this research was experiment. Tools and materials used include 3 Volts of inverter circuit, powerbank and finger lights. Data collection techniques by determining input and output power. Data were analyzed by using Chi-Square. The results obtained in the form of a two phase inverter experiments. Average input power (3.00 ± 0.005) Watt, output power after induction (2,250 ± 0.005) Watt and Efficiency (9.16 ± 0.005). It appeares that there is an increase in output power up to 3 times of input power. This increase in output power can be enlarged as desired by adding windings to the transformer.
