A large current will result in a voltage drop on the line so that it can interfere with other equipment connected to the line. For large-power motors, especially 3-phase induction motors, it will require a large starting current along with a large-power motor, so with motor power above 30 HP and above it is not recommended to start the motor directly without using the starting method. Some of the most commonly used starting methods are Direct on line (DOL), Star-Delta, Auto-transformer, Primary Resistance, Secondary Resistance, Inverter, and SoftStarter. Where the most widely used in the field is the DOL method, but this method still produces a large starting current. If it continues, it will shorten the life of the motor itself. This paper discusses the comparison between starting on softstarter and inverter on starting current. The results of the analysis of the starting current on the softstarter starting is 741A which is achieved in 9 seconds and the maximum torque produced by a 3-phase induction motor is 368.7 Nm.

In general, to detect the presence of heat possessed by an object that is by measuring the temperature of the object. Measurement of the amount of heat of reaction absorbed or released in a chemical reaction by experiment is called calorimetry. While the tool used to measure the amount of heat or calorific value released is a calorimeter. There are two types of calorimeters, namely bomb calorimeters and solution calorimeters. Bomb calorimeter serves as a tool to measure the number of calories or the calorific value of fuels such as bio ethanol and pertalite. The bomb calorimeter was then developed in a simple manner while still showing the function of the device. The stages carried out are defining, designing and developing using the admei 2560 micro controller. The research was carried out at the machine testing laboratory, Universitas Harapan Medan.

Saving electrical energy is an action to reduce the amount of electrical energy use. This study aims to create a control device for saving electricity consumption. Saving electricity consumption does not mean not using electrical energy for something that is not useful, however, energy savings can be achieved by using energy efficiently where the same benefits are obtained by using less energy. This study uses a design method or is designed to be smart electricity using sensors. ultrasonic with arduino uno, where this tool controls daily use in case of forgetting so that no energy is wasted (waste of electricity) or more practical in controlling electrical equipment. Based on the results of tool testing and data analysis carried out, it was concluded that the working system of this tool succeeded in controlling the use of electronic equipment by detecting the presence of an object / human with the help of an ultrasonic sensor with a horizontal area range.
