Abstract

Proses pengisian galon di minum depot air menggunakan pompa air yang dilakukan oleh operator secara manual dengan menekan tombol on atau off. Ketika proses pengisian galon sedang berlangsung, operator selalu memperhatikan kondisi air di dalam galon apakah air sudah terisi penuh atau belum. Operator akan menghabiskan lebih banyak waktu mengamati galon sampai terisi penuh atau hampir penuh, kemudian sakelar di  OFF kan. Ketika tombol OFF diaktifkan, maka sangat mungkin air akan tumpah karena motor pompa belum sepenuhnya berhenti karena masih ada air yang dipompakan oleh motor. Penelitian ini bertujuan untuk mengontrol putaran motor pompa air ketika mengisi galon. Motor pompa bekerja secara otomatis dengan metoda PID, mengisi galon sesuai dengan set point yang diinginkan. Pengujian telah dilakukan pada galon volume 5 liter, 10 liter dan 19 liter. Hasil uji ketelitian sistem mengisi galon galon kapasitas 5 liter 99,40%, galon 10 liter 99,779%  dan 99,865% untuk galon 19 liter.

Abstract

In designing the quadcopter, the main focus is stability and balance. Thus, in the more specific implementation, for example for aerial photography, a quadcopter can also be used as a load carrier. To be able to balance the quadcopter equipped with an orientation sensor on the controller, the orientation sensor includes a gyroscope sensor, accelerometer, and magnetometer. For this reason, it is necessary to have an autonomous stabilizer mechanism that can make the quadcopter stay in a stable and balanced condition even with the additional load. Furthermore, in this research, we will discuss how to determine the PID set points for quadcopter balance that can be tested on loads with different fulcrums. The test is limited to the condition of the quadcopter being hovered for pitch and roll angles. Based on the testing results, it can be concluded that there is a stability response in the Quadcopter. It can be seen from the RMS value obtained that it is by the steady-state tolerance of 2% -5% of the setpoint. Then, the Quadcopter can carry the maximum load with different fulcrums; 950g for fulcrum in the middle of the quadcopter, 580g for the load is placed 6 cm from the middle of the quadcopter, and 310g  if the load is placed on one motor.

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

Body’s height and mass measurement usually are measured with a different instrument without a knowledge to know the ideal body mass index (BMI). Ideal BMI is related to our health condition especially for people who do exercise. Usually people just guess the BMI from a visual condition that sometime give a false measurement. This paper proposes a device that can measured ideal BMI based on Brocha method based on microcontroller. The body’s height will be measured using ultrasonic sensor while the body’s mass will be measured with a load cell. The results show that the proposed device can predict the BMI well. The height measurement has a successful rate of 80%.
