In aviation engineering, Aviation Safety must be an extreme concern for the government as a regulator / facilitator, each component of the Airport sub-system in conducting its operations must still prioritize flight safety and safety. In this case the supporting components and the utilization of AI technology are felt to be very necessary in order to complete the needs will Fulfill Flight Safety by utilizing robots as a medium. In general, robots can be defined as a mechanical device that is able to do human work or behave like humans. One of the human jobs that can be done by robots is fire fighting activities. In this study, researchers designed a Fire Extinguisher Robot to find and extinguish fire. The design of this robot uses an ultrasonic sensor HC-SR04 as a parameter for the robot's path when there are objects around and a fire sensor module as a detector for the presence of fire this robot uses MG995 servo that is useful as a controller hose from the water pump. The circuit in this robot has important components, the Arduino microcontroller functions as the brain of the robot and the L298P Motor Shield Driver functions as a DC motor drive module. If the robot detects a fire while walking, the robot will stop and extinguish the fire using water and candles are used as a fire simulation when a fire is happening.

A electrical motor unbalance a sure thing for power distribution. Especially on the low voltage network side, a higher the load imbalance will be the higher the current arising in the neutral carrier. The current flowing in the neutral conductor will be the loss of electrical power on the network. Therefore, in the distribution of electric power load imbalance must be minimized in order to achieve optimal channeling efficiency. At this research was conducted at the work area of PLN (Persero) district Sibolga, by taking sample 3 substation distribution. Data retrieval is done at two times ie at peak load time and beyond peak load time. From the calculation data obtained shows the magnitude of power losses due to unbalance of the load on the three substations ranging from 0.05% ∼ 4.38%.

A charge controller is needed not only to improve the efficiency of the caddy cars but also to protect the storage batteries. The main function of a charge controller in Candy Cars is to charge the battery without permitting overcharge and deep discharge as an alternative power source. The study aimed to study and monitor a device that will obtain a controlled power supply. The results of the study obtained the design of voltage pulse generator has yielded a significant result, namely the maximum voltage V max pulse battery is approximately 3.08 % and the current on a step up/down module is 12.5 %
