This study aims to design the storage of personal with a dual security system based on Arduino microcontroller to minimize the occurrence of theft crimes without using violence. This research was conducted using engineering research methods. The results of this study are the first key is opened using...

Carbon monoxide (CO) gas in the cabin of a vehicle affects the health of passengers and can even cause death. This is caused by poor ventilation so that the exhaust that leaks into the car and is slowly inhaled by the person in the car. Carbon monoxide is an odorless, colorless, tasteless and non-irritating...

The purpose of this study is to apply load cell sensors on gallon size detectors for Internet of Things-based refill depots that can fill water into gallons and record the number of gallons that have been filled into the database which then the records can be accessed through the internet in realtime....

Interdigitated metal–semiconductor–metal (MSM) photodetectors based on InAlAs/InGaAs materials have attracted much attention for applications in high-speed optical-fiber communication systems which need efficient light detection in the 1.3-1.55 µm range [1]. The performance of thin-film inverted MSM...

The problem of this research is to generate electrical energy in the power plant which is located far from the load center, so it requires a transmission line in order to be distributed to the public. The purpose of this research is to find out the ratio on the primary (20,000Volt) and secondary (400Volt)...

X-Ray Plane is a tool that works using X-ray radiation for fluoroscopy and radiographic purposes. This beam is emitted from the tube directed at the body part and will be captured by the film, so that an image of the illuminated part of the body will be formed. X-rays are produced in a vacuum glass tube...

The growth of communication users, especially data packets, is increasing while telecommunication network facilities is not yet maximized to accommodate more and more users, especially suburban and rural areas whose population spread is uneven. So that there is a solution with the implementation of LTE900...

Indonesia is located in an equatorial region with an abundance of solar energy, with an average solar radiation intensity of 4.8 kWh/m2 per day. It can be used to build solar power plants. This research aims to estimate and plan the efficiency of a solar farm so that the power produced in the faculty...

Case-based reasoning is a new approach that can be used to diagnose disease in addition to using expert systems or other approaches, which are part of artificial intelligence. Case-based reasoning can diagnose diseases based on visible or perceived clinical symptoms. This study tries to build case-based...

The use of electricity has become a major need for all people. The amount of electrical energy consumption by each consumer is measured using an electrical device, namely a kWh meter. Manually recording the meter by PLN officers to the customer’s house is certainly not efficient because it requires more...

The increase in air pollution in Indonesia is a serious problem. Health problems due to air pollution can cause damage to the lungs or cause eye irritation. One of the harmful gases contained in exhaust emissions is carbon monoxide (CO). This study aims to design a system capable of detecting and monitoring...

The experimental electronically controlled plasma power system is presented, with an estimated heat output ranging from 8 to 50 kW, and an electrical output ranging from 5 to 35 kW. The installation is based on the physical principles of ion and plasma fluxes compaction with discrete changes in the control...

Management of the amount of water in daily life is very necessary in human life. As the amount water used is increased will impact the bill of payment. This research focus on how to manage the water flow by a series of instalation relate to Internet of thing (IoT). The objective is to control the valve...
