Polycrystalline photovoltaic panels are a tool for converting photon energy from sunlight into electrical energy. Installing photovoltaic panels outdoors can cause dust to accumulate on the dust surface. Experimental studies were carried out by sprinkling 3 grams of sand and brick dust measuring less than 425 µm. Based on the results of measurements and analyzes that have been carried out, the…
An induction heater or what can be called also an induction heater is a device or circuit that is capable of producing heat and heating objects with an induction system. The principle of heating due to the presence of eddy currents generated by the magnetic flux originating from the coil that is energized by alternating electric current. This induction heater has been widely used in all fields,…
The discussion of the peak current of lightning strikes is very important for research. Prevention of threats that can be caused by very high lightning strikes is an important thing to research. The peak current of lightning strikes is the main parameter in studying and understanding the characteristics of lightning and the impact on human life and safety. This research was conducted using a Pa…
ICT (Information Communication Technology) has become an integral part of improving the quality of higher education. ICT can be utilized to improve in the learning and teaching process, researching, college management, and library services. Advancement of technology in this field has also made significant progress in various regions such as America, Europe, and Australia, and even have reached …
Currently, security systems can be implemented for surveillance in rooms that are only accessible to authorized or relevant personnel. However, the methods applied in Closed-Circuit Television (CCTV)-based security systems still cannot detect and recognize faces from a sufficient distance and have not been directly implemented. Therefore, this research aims to develop a room security system tha…
The 20 kV distribution system often experiences short circuits disruptions due to external factors, which necessitate reliable operation of protective relays to respond appropriately. Based on monthly recorded data, short circuit disruptions have occurred in the Bali and Papua feeders at the Keramasan Main Substation. To identify the causes of these disruptions, the author conducted an analysis…
One of the important components in the distribution of electric power is the electrical conductor. The ability to conduct electricity to conduct electric power is greatly influenced by the quality of the conductor and its resistance. The resistance of the conducting wire can be influenced by environmental conditions with varying temperatures. Temperature is the level of heat in an object and on…
Currently, home security systems are widely used as an effort to protect against crime. Security system needs to be equipped with the ability to detect body temperature to reduce the spread of COVID-19. Temperature screening is generally used a thermometer gun. However, the use of thermometer guns is limited and cannot be combined with security systems. So, in this study developed a smart lock …
Body temperature is a symptom that can be used to indicate someone suffered from COVID-19 when his temperature exceeds the normal temperature. To ease the separation of groups of health people from those who are above normal temperature, face recognition can be used to recognize someone contactless. Thermal image of face can be used as an approach to not only perform face recognition, but also …
