Abstract

The Oxygen Analyzer is a tool for measuring the oxygen content in a gas exhaust system. The Oxygen analyzer is used in various fields including the fields of industry and health. In the health sector, the Oxygen Analyzer is used to measure oxygen content in Continuous Positive Airway Pressure (CPAP), anesthetic machines, ventilator machines, or oxygen cylinders. In this study the researchers made an Oxygen Analyzer that can read oxygen levels 21% 100% with a reading range per digit. This study uses an oxygen sensor that serves to detect oxygen levels which is set with an Arduino Uno microcontroller. The testing is carried out directly on a ventilator as a comparison tool. The method of data analysis in this study uses descriptive analysis. In this study the tool created was able to detect the value of oxygen levels in the range of 21% - 100% with an average error of 0.01%.

Abstract

In this era, practical, effectiveness and safety in activities are the necessities and demands of life where almost all people make it a priority in their lives. Effectiveness in activities will be obtained by the availability of technology that supports it all. Various efforts have been made by humans to make neat clothes so as to create a clean impression and support various activities, an example of the results of human efforts that are widely used to overcome this is by using an iron. In addition, the majority of the equipment still requires manual operation. Apart from the practical side, but does not eliminate the safety side. So here the author is interested in conducting research on the practicality of use which is later expected to make the use of irons more efficient, practical and safe. The measured parameter is how the DS18B20 temperature sensor functions as a temperature response receiver that sends a signal to the temperature sensor module which will activate or deactivate the iron through a smartphone. The results of this study that the device is able to send a signal to the smartphone and if the temperature produced by the iron exceeds the maximum limit a warning sign will appear on the smartphone, and the user can operate the iron online and remotely using a smartphone. The speed of response received by the tool is also to be forwarded to the iron or smartphone is also in accordance with needs.

Abstract

Indonesia is an endemic area for the spread of one of the most popular ornamental fish, namely the largest betta fish in the world. In exploring their hobbies such as raising ornamental fish such as betta fish, efficient and automatic tools are more needed by betta fish farmers in aquariums today, when they have no free time or are drained by other work. This study aims to be a more automatic and efficient tool for everyone to feed fish, provide lighting, and drain aquarium water automatically, so that owners of ornamental fish do not have to worry about what ornamental fish need in the aquarium. The feeding system, in this case uses an Arduino-based control that controls the servo motor as an open and close system as the exit of fish feed into the aquarium. Aquarium lighting system, in this system uses a light sensor type LDR (Light Dependent Resistor). Automatic aquarium drain system, controlled by Arduino with water pump output. In the research, the LDR sensor will give a signal to the relay and give output to the 220 V lamp, that is, if the light intensity is below 028.7 Lux, which is above half past 6 pm and will turn off the 220 volt lamp if the light intensity is above 203.4 Lux, which is above 6 am. The servo motor will operate twice a day for feeding according to the betta fish feed needs, which is 2 times a day. The water pump will work every 4 days to drain the water automatically according to the turbidity of the water based on the time and number of betta fish in the aquarium.
