ABSTRACT Fuse has an important role in protecting electronic devices from overcurrent disturbances. One of electronic device that uses a fuse as a means of protection is the AVR. The AVR on the Koto Gasib 25 MW PLTMG can be damaged due to the failure of the fuse to protect against short circuit fault currents from the feeder. The damage that occurred to the AVR due to the failure of the fuse in…
ABSTRACT In recent time, the use of renewable energy as a resource for electronic devices continues to increase. The process of extracting energy from the environment to produce electricity is called energy harvesting. This energy can be obtained from various sources in the environment, such as heat energy, mechanical energy, and radiant energy. Among the available environmental energy sources…
ABSTRACT Three-phase induction motors can experience an unbalanced stator impedance state in each phase. It is necessary to test the effect of these conditions on the performance, stator current, rotational speed, and efficiency of the induction motor. The research method used is to determine the fixed parameters of voltage (V), frequency (Hz), and power (W). Testing of a three-phase induction…
ABSTRACT An induction machine can be operated as a generator or as a motor so that it can be called an induction generator. In a three-phase induction generator with a single-phase output, the loading that occurs greatly affects the value of the output voltage and efficiency. The characteristics of the generator are largely determined by the parameters in the induction generator. The research …
ABSTRACT The need for energy availability is increasing with the increase in population and increased energy consumption by society due to the use of a variety of equipment to support comfort in life. In the processing of fresh fruit tandan (TBS) palm coconut oil that produces palm oil produces output in the form of solid and liquid waste. POME processing with covered lagoon technology is a wa…
ABSTRACT In the current development of technology, such as the advancement of smartphones used by people of all ages, fine motor skills refer to the movements of the body's muscles that are influenced through practice and learning. Therefore, games that involve simultaneous arranging and thinking, coupled with auditory stimuli like puzzle-solving and music, can enhance the development of child…
ABSTRACT The telecommunications sector has been continuously developing and expanding each year, making it an indispensable part of everyday operations. Radio Over Fiber (ROF) is a combination of a radio network and an optical fiber cable system that provides a solution for high-speed data transmission with broad coverage, high bit rate, and large bandwidth. Hybrid modulation techniques can be…
ABSTRACT Riau Province has minimal natural disasters, but annual natural disasters are forest fires, floods and COVID-19. Forest fire was carried out to speed up the land clearing process and save costs, but the impact after the forest fire occurred was reduced animal habitat, air pollution, increased heat, increased disease and huge losses for the province of Riau. The floods occurred in Riau…
ABSTRACT The business opportunity for coconut shell charcoal briquettes in Indonesia is very large. Utilization of coconut fruit is oriented towards fruit flesh to be used as copra, oil and coconut milk for household needs, while by-products such as coconut shells have not been utilized much. Modifications were made to the blade, namely changing the distance between the fixed blade and the mov…
ABSTRACT A racing camshaft grinding machine is a machine for modifying a standard camshaft into a racing camshaft. This final project aims to make a racing camshaft grinding machine so that the work on making the camshaft becomes easier because the machine grinds the camshaft according to that desire. The method used is starting from field surveys, ideas, literature studies, manufacture, assem…

ABSTRACT Pyrolysis is a process of thermo chemical decomposition of solid materials into solid, liquid and gaseous forms through endothermic reactions. Therefore, the design of a pyrolysis reactor is very important so that the pyrolysis temperature can be reached so that products that can be used are formed, including charcoal, bio-oil, and flamable gas. The life of modern humans depends on th…

ABSTRACT The rapid development of the oil palm plantation industry is currently causing more and more waste to be formed, one of which is palm oil frond waste. Palm fronds have a carbon content of 81.25% which is quite high so that they can be used as activated carbon as an adsorbent which is useful for anticipating or minimizing Cu2+ ion pollution in the environment. This study aims to study …

ABSTRAK A tool for measuring and storing 3-phase induction motor current data that is useful to help the public know where the damage to the induction motor has the smallest percentage of damage to the 3-phase induction motor rotor so that it can be monitored so that further damage does not occur. This tool is equipped with Arduino Uno as a control center to process current sensor data which i…
ABSTRACT This fish feeding tool is very useful to help the community in raising fish, this tool can provide fish feed automatically. This tool is equipped with Arduino Uno as a control center to process proximity sensor data as a feed detector and RTC as a time setting that will be displayed on the 16×4 LCD as time information and feed availability. If it has entered the predetermined feed sc…
ABSTRACT The temperature of the human body can easily change according to the surrounding temperature. Indonesia's tropical climate and global warming are also other factors that make the weather unpredictable. To overcome this problem, a tool is needed to help stabilize the temperature in the human body. One of these auxiliary tools is a fan, but the fans that are widely used today are still …
