ABSTRACT Induction motor is a type of electric machine that is widely used because it has high reliability and low price. Given its vital role, a good protection system is needed so that it can protect the motor when disturbances such as overcurrent, overvoltage, undervoltage and underfrequency occur which can cause damage to the induction motor. The method used in this study is an experimenta…
ABSTRAK The cultivation of fish seeds is widely practiced by Indonesian people as a livelihood. The farmers usually manually feed the fish by scattering feed in each pond of uncertain size. Not only does this consume time, but manual fish feeding also lacks a regular schedule, resulting in inefficiency. IBased on this problem, the researcher proposed an automatic fish feeder dispenser tool bas…
ABSTRAK In the operation of an electric power system one of the most important issues is stability. The imbalance between the mechanical input power and the electrical load power in the system causes the generator rotor speed (system frequency) and voltage to deviate from normal conditions so that it will disrupt the stability of the system. In this research a simulation of SMIB without PSS wa…

ABSTRACT A DC-AC converter (inverter) is one of the electronic devices used to convert DC voltage (direct current) to AC voltage (alternating current). The output of the DC-AC converter can be an AC voltage with sine wave, square wave, and quasi-square wave forms. The DC-AC converter really functions as a backup power provider, providing emergency power when the power goes out. In addition, in…
Motorcycles are vehicles that we commonly encounter in this modern era. Riding a motorbike at high speed is an act of violation as indicated in the Government Regulation through the Minister of Transportation (Menhub) Number 111 of 2015 concerning the setting of speed limits. Driving at high speed also poses a high risk of accidents. In the Riau University campus area there are still frequent c…
