Harmonics causes an increase in the current flowing in the neutral wire due to the use of unbalanced non-linear loads. THDi simulation was conducted in this study using MATLAB Simulink software and calculating power losses. Based on the measurement results it is known that THDi transformer one exceeds the standards set by IEEE 519-2014. THDi simulation results in the existing conditions show the percentage of phase R of 17.27%, S phase of 16.40%, phase T of 16.24% with a current flowing on a neutral wire of 19.64 A. Based on the results of simulations with earth resistance 11? shows the percentage of THDi in the R phase 15.69%, S phase 14.70%, T phase 9.83% and the current flowing on the neutral wire is 1.013 A. When the earth resistance is changed to 8? THDi in the R phase by 15.62%, the phase S 14.67%, T phase 9.81% with current flowing on neutral wire 1,297 A. While the earth resistance is reduced to 4? THIn the R phase 13.57%, S phase 14.51%, T phase 9.80% and the current flowing on the neutral wire is 2,518 A. The power losses in the one-time transformer when the existing conditions are 8,796 kW, while the earth resistance 11? is 6,079 kW, while the ground resistance 8? is 6,032 kW, and when 4? is 5,880 kW.

The selection of lightning rods in the Nusa Dua Highland housing estate aims to secure the housing area from lightning strikes, because the housing has not been protected by lightning rods and earthing system components which are very difficult because they have rocky soil types. The average number of lightning strikes per year with a density value of 31 per km2 and population density, land use for houses and buildings have a very high level of vulnerability, so lightning rods are needed to secure the Nusa Dua Highland residential area. Lightning rods to be used are conventional lightning rods or Evo Franklin (E.F). The selection of the type of lightning rod is done by analyzing technical and economical. The results achieved in this study are the type of lightning rod suitable for housing Nusa Dua Highland is the E.F lightning rod with an earthing system. Because from technical analysis, 1 E.F lightning rod is able to protect the entire residential area with 37,994 m2 of protection area from the 22,444 m2 housing area, while 1 conventional lightning rod is only able to protect 1 house from a total of 147 housing units. In terms of economical cost of installing E.F lightning rods is much cheaper at a cost of Rp. 104,450,000. Conventional lightning rods cost Rp. 14,390,000 for 1 housing unit and to protect the entire housing using conventional lightning rods needed 147 lightning rods at a cost of Rp. 2,115,390,000.

Garbage is often a problem, especially in big cities. The average amount of waste in Indonesiais 64 million tons / year, while the number of landfills in Indonesia is around 400 with a landfill capacitythat can accommodate 233 kg / day. Not to mention the unpleasant odor and dirty city views causediscomfort. This is where a solution is needed by leading to the use of technology in an effort tocreate a clean environment by reducing the level of waste accumulation and reducing waste litteredwith the Internet of Things technology. This tool is able to monitor the height of waste and gas contentvia the web. The internet system uses the MCU Node module with energy supply from solar cells.Working voltage of the control system is 5V, a stepdown module is needed to reduce the batteryvoltage from 12V to 5V. Detection of the height of waste using a PING sensor and to determine thelevels of methane gas using the sensor MQ-135. From testing at Student Center LT 4, it was foundthat the garbage accumulated on Saturday by 60 cm with 126 PPM methane gas levels that indicatedunhealthy. This monitoring system can last up to 7 days because it uses solar cells, but this canexperience changes due to the intensity of the sun.

The scientist of Nikola Tesla creat the Teslacoil which will become the forerunner of wireless electricity distribution that can turn on lights bymeans of air. The purpose of this study to determine the effect of distance on voltage, current,power, electromagnetic induction emitted and the flux of light. The method of analysis usescalculations, tests and measurements obtained from primary data. In general, the data used inthis thesis are the input voltage 5 V and current 1 A, the voltage result by the high voltagegenerator was 400 kV, the number of secondary windings was 1400 coils, the number ofprimary turns was 10 coils, the pipe diameter was 3.81 cm. The diameter of the torus was 8 cm,the distance of the spark gap was 1 cm, the lamps used were TL 8 W, 5 W, LED 5 W andincandescent lamp 5 W, the test used variations in the distance of 1 cm, 3 cm, 5 cm, 7 cm, 9 cmand 11 cm from transmitter to load.From all the tests carried out with distance variations to voltage, elektromagneticinduction and flux, it was found that distance greatly with TL 8 W affected the voltage was 0.2 V,electromagnetic induction was 22859,2 x 10-7 Tesla and light flux emitted by the lamp was 4.8 x10-4 Lumen. If the radius or distance of the transmitter was got closer, the value could receiveget bigger and the farther the value could get smaller.
