Abstract

The Army Aviation Operations Task is carried out in remote areas that still have minimal airport services, the process related to refueling for aviation helicopters is an obstacle to the implementation of the main tasks of aviation. So a tool is needed to make the process more effective. In this study, a method is used to obtain data for quantitative research to prove the hypothesis. The method is known as the Development Life Cycle Waterfall Diagram and experimental research. Currently still using a hand pump, therefore a portable tool is needed and uses an electric pump. specifically for fuel controlled by Arduino and an Android application as an input for a filling command and can store filling data. In this case, the tool system uses supporting components, namely batteries, Bluetooth hc 05, 5v relays, and flow sensors. With the research of portable pump tools, the process can be more efficient than hand pumps. When refueling a helicopter, simply by inputting the filling value from the Android application, the filling is running and the filling data is stored in the Android file.

Abstract

Servo motors are essential actuator components in the modern mechatronics ecosystem that demands angular positioning precision with minimal error rates. In the control system development phase, direct testing on hardware is often at risk of mechanical damage due to programming errors or current surges. This study aims to conduct an in-depth analysis of the response characteristics of servo motors through a digital simulation approach as a preventive and validative step. The research method applied was a software-based laboratory experiment using the Proteus 8 Professional with an Arduino Uno microcontroller as the central control unit. The main focus of this test lies in the evaluation of the accuracy of the motor angular movement against the pulse width modulation (PWM) provided through the Servo standard library. Data is collected through Virtual Terminal observations and position indicators on virtual servo components. The results show that the Proteus simulation is able to represent the dynamics of angular motion linearly with a 100% accuracy rate to theoretically entered work cycle parameters. The study concludes that the use of virtual modeling is not only effective in minimizing the risk of physical failure.

Abstract

Studi ini menyelidiki bagaimana kapasitor kopling (C1, C3) dan kapasitor bypass (C2) mempengaruhi titik kerja, penguatan mid-band, dan respons frekuensi penguat BJT konfigurasi common-emitter transistor BC547. Perhitungan teoritis, simulasi Proteus, dan pengukuran laboratorium digunakan dalam prosedur ini. Semua ini dilakukan pada VCC = 15 V dan Vin = 10 mV (peak). Hasil utama termasuk penguatan mid-band Av sebesar 11,3 kali (21,0 dB), frekuensi cut-off bawah F1 sebesar 90 Hz (pengukuran laboratorium), F2 sebesar 1 kHz, dan F3 sebesar 450 kHz (pengukuran laboratorium). Toleransi komponen, kapasitansi parasitik transistor, dan ESR kapasitor menjelaskan perbedaan antara eksperimen, simulasi, dan teori. Hasil menunjukkan bahwa kapasitor kopling memainkan peran dominan pada F1 dan C2 dalam meningkatkan Av tanpa mengganggu kestabilan bias DC.
