ABSTRACT In general, toilets in Indonesia still use a manual system. Especially on the lighting system and toilet indicators are in use. Turning on the lights using a switch that you forgot to turn off has an impact on wasting electrical energy. Then it often happens that toilet users do not know the toilet is being used or not. This problem requires a solution or solution by updating the toile…
ABSTRACT The Solar Power Plant (PLTS) during the day will charge the battery and supply the load up to a maximum battery voltage of 12,73 Volt-13,8 Volt based on the state of charge standard batteries. ATS is used to transfer connections between PLTS and PLN energy sources. In this study where ATS is controlled by Zelio Logic Smart Relay, the use of Zelio Logic Smart Relay is intended to repla…
ABSTRACT The design simulation was carried out using optisystem software for Free Space Optics (FSO) analysis using the fso-mimo technique in rainy and windy weather in Pekanbaru city. Free Space Optic (FSO) communication is one of the fastest growing wireless optical technologies. One of the impacts of using the atmosphere as a propagation medium is a large attenuation. The atmospheric co…
ABSTRACT Lightning is one of the main sources that cause failure in the transmission overhead line system where the transmission system experiences overvoltage. Lightning can strike a phase line if the ground wire fails to protect it and causes the phase line to overvoltage. A direct strike on the transmission phase wire results in shielding failure while a strike on the ground wire or tow…
ABSTRACT Geographically, Indonesia is located on the equator which has two seasons, namely the rain season and the dry season. In the dry season, the sun's heat is needed for various needs, one of these is to drying wet clothes. The drying process cannot be monitored directly. Therefore, an automatic clothesline system was designed. This design uses Arduino Uno as a microcontroller. Light …
ABSTRAC Monitoring network devices is very important to find out problems or troubles that occur in a network, such as the accesspoint used in the PT. Citra Karimun Mandiri. If an unwanted problem occurs, the technician cannot immediately take immediate corrective action, so it takes a long time to analyze and resolve the problem that occurs for smooth and normal Internet access. In previ…
ABSTRACT Computer networks have two data transmission media, namely wired and wireless. National Housing Griya Nusantara Pekanbaru is housing that has wireless network (wifi) facilities. Wifi networks are very vulnerable to attack threats, because the communication that occurs is open. A good security system is needed to be able to maintain the security of user data in order to avoid attacks b…
ABSTRACT Cancer is one of the leading causes of death in the world. Breast cancer is the abnormal growth of body tissue cells that turn into malignant cells. The best way to treat cancer is to know the symptoms early so that it can minimize the spread of cell damage to other body cells. One of the applications of Ultra Wide Band technology that is currently being developed is used to detec…
