The sensors used in the manufacture of this tool use IR sensors and Ulteasonic sensors. The IR sensor functions to detect existing objects, in this study the object used is the hand. Ultrasonic sens…
ABSTRACT Formalin is very dangerous for human health for we have to know whether a food contains formalin which is generally used to preserve food. For that we need a formaldehyde detector in food that uses an Arduino Uno as a control. The use of this project makes it easy to detect formaldehyde content without having to carry out laboratory tests. This tool uses the HCHO sensor as a device fo…
ABSTRACT Every country is racing in developing renewable energy potential with the natural resources they have, this is because renewable energy can be a sustainable and environmentally friendly energy supply. The Vortex turbine is one of the hydropower generator turbines which has the potential as a source of renewable energy even on a small scale. The working principle of the vortex turbine …
ABSTRACT Turbine vortex is one of the picohydro power plant water turbines. There have been various studies conducted on turbines vortex, but the efficiency obtained by each researcher has a different value. So the real efficiency of the turbine vortex can not be determined. Therefore the turbine design is carried out vortex to get real efficiency. The design is carried out based on the result…
ABSTRACT The application of power generation technology using solar cells to utilize the potential of solar energy is the right solution in reducing dependence on energy from PLN. In a solar energy generation system there are objects that need to be monitored, namely solar cells, solar charge controllers, and inverters. The design of this monitoring system consists of a voltage divider circuit…
ABSTRACT Breast cancer is one of the most terrifying types of cancer for women worldwide, including in Indonesia. Detecting the early symptoms of cancer as soon as possible is a preventive measure to reduce the mortality rate of the disease. One technology that can be used to detect objects, specifically in the field of medical diagnosis, is the micro-wave imaging system using Ultrawideban…
