Scoliosis is a spinal deformity characterized by an abnormal curvature, typically shaped like the letter C or S. The exact cause of scoliosis is unknown, but the majority of cases (75-85%) are idiopathic scoliosis. Therefore, the aim of this research is to design an intelligent posture system using Internet of Things (IoT) technology for individuals with scoliosis. The "skoming" system uses fle…
The distribution of electrical power systems cannot be optimally utilized by consumers due to power losses occurring as a result of technical and non-technical disturbances. The causes of power losses in distribution lines are the resistance content in the conductors or the condition of the network itself, such as the increasing length of the network. Distribution networks are more susceptible …

The lecture attendance system is an important component in academic administration management to ensure student attendance. In this research, we developed a lecture attendance system using RFID (Radio Frequency Identification) sensors to increase efficiency and accuracy in recording attendance. This system consists of several main components, namely an RFID module, microcontroller, RTC (Real-Ti…
In the process of distributing electrical energy there are often disturbances caused by internal disturbances and external disturbances. External disturbances that often occur are lightning strikes. This disturbance can cause overvoltage, to anticipate the risk of transformer damage caused by grounding system failure. So a good grounding system is created. In electric power systems, grounding r…
Electric bicycles are now widely favored by the public. As an alternative vehicle that utilizes electric energy, the use of electric bicycles is very practical and does not produce emissions. The electric energy stored in the battery is converted into kinetic energy by the electric motor. The purpose of this study is to design a speed controller for the bicycle's drive motor using the Pulse Wid…
It is undeniable that the role of electrical energy is very important in people's lives in the current era of globalization. Therefore, to keep up with the rapid increase in electricity demand, it must be followed by improvements in the quality and reliability of the electrical energy produced. One that plays an important role in the distribution of electrical power is the transformer. In order…
The problem that arises from the use of PV is that the Output power often does not reach the actual maximum power, especially in conditions of low solar radiation. Solar panels have their own optimal operating point called MPP. The characteristics of this MPP will change depending on sunlight and temperature. MPPT is used to make the solar cell operation point work at the MPP point. In this stu…
The government's main policy direction regarding national energy is energy conservation to increase the efficiency of energy use and utilization (demand side) and energy diversification to increase the share of new energy and renewable energy in the national energy structure (supply side). This process includes an energy audit, which is a method for calculating the energy consumption level of a…
High-voltage plasma generation is a type of voltage that is widely utilized in environmentally friendly technology. High-voltage plasma can be designed using a flyback transformer full bridge inverter topology using MOSFET as a switching device. The MOSFET is controlled by an IC TL494 control circuit connected to a 15-volt DC voltage source. The high-voltage side of the flyback transformer is c…
One of the technological developments in the transportation sector that can be found is the parking service system. Currently, parking in a mall still uses parking attendants who only control each vehicle that enters and also do not pay attention to the capacity of the parking area. So driver errors often occur due to lack of information on parking capacity in a parking area. The solution to th…
The ever-increasing need for electrical energy has encouraged energy providers such as PT PLN (Persero) to offer prepaid kWh electricity services, providing flexibility for users in managing energy usage. However, the current electricity token Input system is still manual and limited by distance. This research aims to find a solution by designing an IoT-based Keypad pressing device that can be …
Traffic lights is a traffic control tool at intersections and are useful for regulating smooth traffic at intersections to avoid traffic jams. Current traffic lights still have a weakness, namely the fixed duration of the light timing at each intersection. This weakness is what causes traffic jams that often occur at road intersections. Congestion also occurs at certain hours, for example when …
