Abstract

Terjadinya perubahan iklim yang ekstrem di Indonesia saat ini berdampak pada kenaikan suhu udara secara mendadak, hal ini dapat disebabkan karena tingkat polusi udara yang tinggi. Tingkat polusi udara yang tinggi disebabkan oleh penggunaan energi fosil secara terus menerus sebagai sumber energi utama, mulai dari pembangkit listrik bertenaga fosil hingga banyaknya kendaraan konvensional yang masih digunakan. Pembangkit listrik tenaga angin (PLTB) mampu menjadi solusi permasalahan penggunaan energi fosil. Angin dapat memutar generator turbin untuk menghasilkan energi listrik. Kecepatan angin yang melewati turbin sangat berdampak terhadap besarnya energi yang dihasilkan.  Kecepatan angin yang tidak stabil akan mempengaruhi proses pembacaan data output karena proses pengukuran output turbin angin masih menggunakan pengukuran manual (analog). Sehingga dalam proses pembacaan data output menjadi terganggu dan hasil yang didapat belum akurat. Tujuan dari penelitian ini adalah melakukan analisa monitoring terhadap energi yang dihasilkan dari suatu pembangkit listrik tenaga angin berbasis Internet of Things (IoT) menggunakan prototype yang telah dibuat. Prototype yang telah dibuat menggunakan Sensor INA 219 sebagai pengukur energi dari turbin dan NodeMCU sebagai pengontrol serta pengirim data yang dihasilkan sensor ke software Blynk. Dari hasil pengujian alat monitoring PLTB, diperoleh nilai tegangan yang dihasilkan turbin cukup stabil yaitu antara 0.86 V hingga 0.87 V dengan daya terbesar yang dihasilkan selama pengujian adalah 6370,93 mW. Perbedaan jarak turbin dengan kipas angin memberikan pengaruh yang signifikan terhadap besarnya nilai arus yang dihasilkan. Nilai arus yang dihasilkan selama pengujian yaitu 0,1 mA hingga 7,3 mA. Perubahan nilai tegangan tidak mempengaruhi kondisi LED.

Abstract

This article describes the design and implementation of behavior-based robotic (BBR) algorithm on a wheeled mobile robot (WMR) Pioneer P3-DX in a maze exploration mission using V-REP simulator. This robot must trace and search for targets placed randomly on a labyrinth. After successfully meeting the objective, robot runs back to home position using the nearest path. Robot navigation system applies BBR algorithm to reach the target using behavior modules which work simultaneously to obtain the desired robot’s trajectory. The most fundamental behavior which is highly affordable to build on the robot system is a wall-following behavior. To make the robot could follow the wall in a safe, smooth and responsive condition, proportional-integral-derivative (PID) controller is applied. PID controller runs by utilizing the reading of sixteen proximity sensors carried on Pioneer P3-DX robot toward the expected wall distance while the robot is exploring the labyrinth. To ensure the designed system works properly, several tests were conducted, including BBR test and PID controller test. BBR test shows that the system can choose the shortest track when returning to home position. The PID controller test produces robot movement with maximum deviation and settling time for about 0.013 m and 30 seconds, respectively.

Abstract

Movement systems of a mobile robot in an industry generally use the concept of differential drive or ackerman steering. However, both methods tend to have low mobility. This paper proposes an industrial mobile robot design with a holonomic concept using mecanum wheels to maneuver in all directions with better mobility. As a commonly used robot in the industrial field, an arm manipulator is combined with a mobile robot. The mobile robot and arm manipulator's mechanical design is made using software inventor and utilizing acrylic as its base material. The electronic design of the robot is created using Eagle software. After the robot manufacturing is complete, then a user interface is made using the processing IDE. Several robot tests are conducted to ensure that the designed robot runs appropriately. From the functional test results, parts of the robot can run well. The smallest error obtained is 5 cm for the robot heading test, and the most significant error is 20 cm. The testing of a servo motor, which is the arm manipulator's primary actuator, showed the highest error of only 2 degrees. Besides, the gripper of the arm manipulator can also hold objects properly.

Abstract

The goal of this project is to measure the speed of an object as it passes through the sensor being utilized. The tool that will be developed as a result of this project has already been designed in software simulation to ensure that it will work as intended. This device uses two infrared sensors as input signals to be processed in accordance with orders.I will be connected to an Arduino Uno through a middle whiteboard as a communication hub between various parts. The parameter used in this tool is the movement of the object going through the infrared sensor because that is what is measured when an object goes through the sensor in this tool. The input data will be processed and then shown on the programmed I2C 16x2 LCD to show the output signal that results from processing the input signal. Making this tool will allow users to minimize unintended incidents and control their speed while driving.

Abstract

Bicopter is an unmanned aerial vehicle (UAV) with the advantage of saving energy consumption. However, the unique two rotors design presents a challenge in designing a controller that achieves good stability, fast settling time, and the ability to overcome oscillations simultaneously. This article proposes a new control method for bicopter that uses a genetic algorithm optimization approach in the linear quadratic (LQ-GA) control method. The GA is used to search for the best weighting matrix parameters, Q and R, in the Linear Quadratic (LQ) control scheme. The proposed control method was tested on a balancing bicopter test platform with an input in the form of difference in pulse width modulation (PWM) signals for both rotors and an output in the form of roll angle. The control system was evaluated based on the stability of the transient response and the generated control signal. The results of the tests showed that the proposed LQ-GA control method has better stability, faster settling time, and smaller overshoot than the existing PI and standard LQ control methods. Therefore, the proposed LQ-GA control method is the most suitable for use in a balancing bicopter system with a non-zero setpoint.

Abstract

Brushless DC (BLDC) motor is a three-phase motor that cannot work directly with DC current but requires electronic commutation to replace the brush function in DC motor. This paper aims to implement BLDC motor driver integration based on bootstrap circuit using Autodesk Eagle. The driver board consist of bootstrap circuit based on IR2110, MOSFETs, three voltage regulator, ESP32 microcontroller and ACS712 current sensor connection, logic level converter, and BLDC hall effect signal sensor conditioning. The research proposes bootstrap capacitor calculation based on charging/discharging capacitor principle and the minimum motor speed rotation. The implemented driver has 14x10 cm dimension tested to drive 24V/135W/6000rpm sensored BLDC motor using six steps commutation with pulse width modulation (PWM) inserted programmatically in ESP 32 to drive the high side MOSFET of the driver without AND gate circuit. The effect of pwm frequency and dutycycle variation to the speed and current of the motor is investigated. The results showed that the driver with both 12 V and 24 V voltage source and 68 μF bootstrap capacitor work optimally in 20 KHz PWM frequency both in open loop and closed loop speed control test. The motor reach 129 W for the largest power and 5250 rpm for the fastest speed in 24 V supply.

Abstract

Sistem presensi pegawai yang menggunakan RFID dan NodeMCU berbasis Telegram merupakan sebuah sistem yang dirancang untuk otomatisasi proses pencatatan kehadiran pegawai. Sistem ini menggunakan teknologi RFID (Radio Frequency Identification) dan NodeMCU (ESP8266) untuk menjalankan fungsinya. Dalam sistem ini, kartu E-KTP digunakan sebagai identitas pegawai dan informasi kehadiran dikirimkan melalui bot Telegram. Sistem ini terdiri dari beberapa komponen utama. NodeMCU berperan sebagai pembaca RFID dan pengirim pesan ke bot Telegram. Modul RFID digunakan untuk mendeteksi kartu E-KTP. Sedangkan bot Telegram berfungsi sebagai media komunikasi untuk mengirimkan informasi kehadiran. Ketika seorang pegawai meletakkan kartu E-KTP di dekat pembaca RFID, NodeMCU akan membaca nomor seri kartu tersebut dan mengirimkannya ke bot Telegram melalui koneksi internet WiFi yang tersedia. Bot Telegram akan menerima pesan tersebut dan mencatat waktu kehadiran pegawai. Hasil pengujian yang dilakukan dengan menempelkan kartu ke RFID reader, jika kartu tersebut valid, maka akan mengirimkan pesan ke bot Telegram yang berisi presensi berhasil dan buzzer sebagai indikator suara akan berbunyi selama 1 detik, sedangkan jika kartu tidak valid, maka akan mengirimkan pesan ke bot Telegram yang berisi presensi gagal dan buzzer akan berbunyi pendek sebagai tanda bahwa kartu tidak valid. Dengan memanfaatkan teknologi RFID dan NodeMCU, sistem ini menyediakan kemudahan dalam melakukan presensi pegawai secara otomatis dan dapat terintegrasi dengan sistem manajemen kehadiran yang lebih besar. Selain itu, penggunaan bot Telegram sebagai antarmuka komunikasi memungkinkan pengguna untuk mendapatkan informasi presensi secara real-time dan memberikan fleksibilitas dalam mengelola dan melacak data presensi.

Abstract

ABSTRAKMakalah ini memberikan analisis perbandingan antara teknik kendali klasik yaitu kendali PID dengan teknik kendali modern pada sistem Eddy current brakes dinamometer. Eddy current brakes merupakan sistem pengereman modern yang membutuhkan sebuah sistem kendali untuk menunjang kinerja pengereman. Selama ini kendali PID lebih sering digunakan, namun di beberapa kondisi dinilai kurang optimal. Dengan demikian, diperlukan pengembangan kendali yang modern dan optimal yaitu full state feedback Linear Quadratic Regulator (LQR). Perbandingan respon waktu pengereman disimulasikan menggunakan Matlab/Simulink. Hasil simulasi menunjukkan respon waktu pengereman pada kendali LQR lebih baik dibandingkan dengan kendali PID, dengan Ts = 2.12 detik, Tr = 1.18 detik, dan tanpa overshoot. Adapun kendali PID, meskipun menghasilkan Ts = 0.27 detik dan Tr = 0.18 detik, namun demikian masih terdapat overshoot sebesar 0.7%.Kata kunci: Eddy brakes, PID, LQR, Matlab ABSTRACTThis paper provides a comparative analysis between PID control as a classical control technique and modern control technique in the dinamometer Eddy current brakes system. Eddy current brakes is a modern braking system that requires a control system to support the braking performance. PID control is often used to be implemented but in some conditions it is less optimal. Therefore, it is necessary to develop a modern and optimal control, such as a full state feedback Linear Quadratic Regulator (LQR). The comparison of the braking time responses were simulated using Matlab/Simulink. The simulation results show that the response of LQR control is better than the PID, with Ts = 2.12 seconds, Tr = 1.18 seconds, and without overshoot. On the other side, PID control, although having Ts = 0.27 seconds and Tr = 0.18 seconds, there is still an overshoot about 0.7%.Keywords: Eddy brakes, PID, LQR, Matlab

Abstract

A solar power plant or photovoltaic (PV) is a generator that converts energy from light into pollution-free electrical energy. However, changes in the intensity of solar radiation and ambeint temperature Photovoltaic (PV) which are not linear are the main problems of PV systems in efficient energy conversion that occurs. Control using the Maximum Power Point Tracker (MPPT) method based on the Perturb and Observe (PO) algorithm which is applied to overcome these problems. Maximum Power Point Tracker (MPPT) itself is a technique for tracking the maximum output power point of the PV system. MPPT will change the working point so that the converter will force the work of the solar panels according to their ability to always reach the maximum power point. MPPT is not a mechanical system that makes the solar panel system move according to the direction of the sun's intensity, but an electronic system that works to optimize the power output from the solar panel. Meanwhile, Algorithm (PO) works by detecting and disturbing the PV voltage periodically by varying its duty cycle, as well as observing the PV power to be able to increase and decrease the PV voltage in the next 3 cycles. This paper presents an analysis of the MPPT PO performance with a standalone system implemented in the campus area. In this study, the applied PV system was able to produce a maximum power of 1626.087 Watts under optimal irradiation conditions and temperature. As well as testing the PV system under radiation and temperature conditions in the location study, namely FT UNNES. The maximum power of the PV system is 227.585 Watt.
