Controlling a differential drive robot balancing system is a challenging task since it is highly unstable, non-linear and under-actuated system. This paper proposes a PID controller algorithm to balance a differential drive robot at upright position. The system model derived using Lagrangian method is discussed. The resulting mathematical model of the proposed closed-loop system was simulated. To verify the system performances, the real time experiments have been conducted. An Arduino Uno and an MPU6050 were used as the main controller and the main sensor, respectively. The PID parameters were manually tuned until the desired performance was achieved. From the simulation and the real time experiment results, the proposed method has demonstrated its capability to stabilize robot at upright position.

In every Unmanned Aerial Vehicle (UAV) task, the power supply used is limited. UAVs are often forced to land when the battery runs out before the mission is completed. The gliding controller is proposed in this paper so that Fixed Wing Aircraft (FWA) can fly with minimal power and can adjust direction, altitude, zero pitch and zero roll stability. The FWA uses a Barometric Pressure Measure (BMP) 180 sensor at the tip of the wing to detect the difference in pressure experienced by both wings, therefore, the direction of the wind can be determined. The information of the wind direction was then used to maintain the desired altitude of the FWA. The Proportional Integral Derivative (PID) control algorithm was implemented to stabilize the FWA altitude to keep cruising or flying in a flat position. Real-time experiments using FWA have been conducted. It can be observed that the FWA was able to air with automatic glider mode for almost 2 minutes. Tests carried out include altitude data, roll and pitch movement from BMP180 sensor readings, the glidding performance has been observed with respect to the altitude, roll and pitch errors. It was measured that the altitude, the roll and the pitch errors were 1.74%, 0.23% and 0.34%, respectively.

The first-ever Covid-19 virus Pandemic was found in Wuhan, China in December 2019. This virus has become a pandemic and become the cause of death for many people. This Virus spreads rapidly and that's why it becomes every country's concern. The Covid-19 Virus can be detected by a method called PCR Swab Test. The Swab and PCR method can't be separated from defining a suspect result of Covid-19. Even more, Swab tests and PCR have become an important requirement for traveling. But the Test is so costly and takes a long time to get the result where it becomes a new problem. Hence, there is a device called Poltekad Electronic Detector that can detect a suspect of Covid-19 based on Body Temperature, Blood Pressure, Heartbeat, and Oxygen level on blood. All these parameters will be used by a smart system to draw a conclusion and showing it on a Web Server. This research using some of the methods used in sensor calibration thus makes the output of the device is corresponding to the Health Equipment Standard. According to the result of this research, the device could read a parameter and then draw a conclusion about the suspect and also send the data to the Web Server so the data can be accessed from a PC or a Smartphone. The result from the Web Server can be printed in PDF Format.

Indonesia is an archipelagic country with 17,504 islands, geographically Indonesia is located between the continents of Asia and Australia and the two Pacific and Indian Oceans. In support of maintaining the sovereignty of the Republic of Indonesia, especially the land dimension, equipment is needed to support the main tasks. The majority of the equipment used requires electrical energy in its use. Meanwhile, in carrying out their duties, while maintaining sovereignty in border areas, the geography is in the form of tropical forests with minimal fields of electrical energy as an energy supply. Therefore, researchers develop a source of electrical energy by utilizing footsteps, which is a solution for recharging electrical energy. In developing the tool, the method used is fast charging. The mini generator located on the shoe is expected to be a solution for recharging as a supply of electrical energy for equipment to support basic tasks. Capacitor Bank is used to stabilize the input voltage of the mini generator so that recharging becomes more stable and charging faster.

Teknologi canggih dirancang dengan tujuan mampu memberikan manfaat yang positif bagi manusia di berbagai aspek, contonya dibidang militer. Produk-produk yang dibuat untuk keperluan militer harus memilki standar yang tinggi. Merubah proses manual menjadi otomatis (sistem otomasi) pada proses produksi, maka timbulnya kesalahan kerja dapat diminimalisir. Sistem otomasi umumnya merupakan sistem kendali yang berurutan (sequential) sehingga kecil kemungkinan terjadi error. Anggota militer harus mampu menguasai sistem otomasi tersebut. Tujuannya agar dapat memonitoring sehingga proses produksi dapat dipastikan berjalan sesuai dengan yang diharapkan. Melalui kegiatan pelatihan dan pendampingan kendali sequential, diharapkan 15 bintara mahasiswa memperoleh gambaran tentang alur atau proses pembuatan alat militer. Penerapan metode analisa kasus dan simulasi mampu menarik minat sehingga proses belajar dapat berjalan secara efektif dan efisien. Trainer otomasi mampu bekerja sesuai dengan ilustrasi yang diberikan membuat bintara mahasiswa menjadi lebih kreatif dan memicu untuk dapat meciptakan teknologi baru. Untuk menghasilkan teknologi baru perlu didukung dengan fasilias yang lebih memadai.
