Abstract

Diabetes mellitus and gastric infections can be detected through bad breath bad breath (halitosis). Halitosis is a condition where the smell of bad breath occurs when a person exhales (usually smells when talking). This study aims to create an oral health identification and classification system (halitosis). TGS-2602 gas sensor will detect gas levels in the mouth of the patient, and send data in the form of an analog signal to the ATmega 328 microcontroller. By programming the data read on the Raspberry Pi, the data from the microcontroller is stored in a file and then the data is processed using the Fast Fourier Transform method. (FFT) so that the desired data pattern is obtained. The data pattern of the Fast Fourier Transform (FFT) output will be used as input data on the Learning Vector Quantization (LVQ) neural network method. System testing is done to people with halitosis and not halitosis bad breath. The results showed that the percentage success rate of sensor responses to mild halitosis samples was 25%, moderate halitosis samples were 50%, acute Halitosis samples were 50% and non-halitosis samples were 100%.

Abstract

In this study, the total dissolved solid (TDS) in water was made using conductivity sensor which the sensor works by using the principle of conductance that is the ability of the solution in delivering the electric current, so the more content of solute contained in the water the greater also the value of its conductance. The measurement results of the sensor will be compared with the next setpoint value will be used to turn on the booster pump which will do the filtering process in order to decrease the TDS water content by using RO membrane. The performance of sensor readings when first used is boosted by the time at which the system takes 3 minutes to reach a stable state, while for the whole system is influenced by the volume of water that will decrease its TDS level. The test results are presented in the form of graph of change of TDS water content over time, the difference of time required to decrease the TDS level by 15 ppm for 1 liter of water for 6 minutes, 2 liter of water for 10 minutes and for 3 liters of water for 16 minutes.

Abstract

The development of computer technology in Indonesia is currently growing rapidly. In line with this the development of the Potato Seed Center (BBI) of potatoes was also developing, as was the case at the Kerinci Regency mother's seed plant. Processing of potato hatchery and hatchery development reports has not been computerized because it still uses Microsoft Excel, causing some problems including making reports on the development of potato hatcheries and searching for data takes quite a long time. This led to a weak processing of hatchery data processing systems and the development of reports on the development of Kerinci Regency potato seeding. Seeing the above problems, a potato seeding information system at the Central Seed Agency (BBI) was made using a C # programming language that had used a database and used Crytal Report to assist in the development of a report on the development of potato seedlings in the potato seed plant in Kerinci district.

Abstract

Mobile Robot is one robot that much used to help out man. Micromouse mobile robot is one robot that made to can find the route shortest in a maze. Flood fill algorithm is one way to find the route shortest by doing maze mapping, where the robot will compare the value of each cell and moving toward the smallest cell. In the research, the micromouse mobile robot was designed using Ultrasonic PING sensor to detect obstacles and Arduino Uno that will control the movement of DC motor. The robot will search a route shortest based on maze mapping that it has passed. The robot was tested on three mazes, where each maze was tested 10 times and obtained success level on the first maze of 80%, the second maze of 70% and the third maze of 70%.

Abstract

In this study, a monitoring system was generated to send data about temperature, humidity, and ammonia gas from a dairy cow cage. This system also provides notifications and recommendation to the owner to carry out certain actions based on data obtained from the dairy cow cage. This system consists of three main components, namely the web server monitoring devices and an application on mobile device. Furthermore, monitoring devices consist of a microcontroller, DHT22 sensor, MQ-135, and ESP266. The microcontroller sends data to the web server and the device moves continuously to notify the state of the dairy cage. From the test results, it is known that the system can send data correctly to mobile devices and web servers. Notification of abnormal conditions is given in an average of 39 seconds.
