Abstract

Dalam suatu sistem otomasi industri diperlukan suatu kontroler, salah satunya adalah Programmable Logic Controller (PLC). PLC dibuat untuk mengubah sistem kerja mesin yang dulunya bekerja secara konvensional menjadi sistem yang dikendalikan dengan menggunakan komputer. Penelitian ini bertujuan untuk merancang sistem kendali otomatis menggunakan PLC pada press roll di salah satu building tire machine. Fokus penelitian yang dilakukan pada sistem kontrol press roll ini meliputi pemasangan panel kontrol PLC dan program PLC dengan software GX-Works 2. PLC yang digunakan adalah PLC Mitsubishi tipe-Q dengan modul input QX41 dan QX42 dan modul output QY41P dan QY10. Metode yang digunakan dalam penelitian ini adalah metode Research and Development (R&D), yaitu metode untuk mengembangkan sistem yang sudah ada sebelumnya. Pengujian sistem dilakukan dengan mengukur tegangan kerja pada terminal input dan output PLC serta menguji kinerja sistem kontrol secara keseluruhan. Hasil yang diperoleh pada pengujian terminal input menyatakan bahwa sistem input bekerja dengan normal. Kemudian pada pengujian terminal output didapatkan nilai persentase error (% error) pada terminal output Y68 sebesar 0,08%, dan terminal output Y7F sebesar 0,04% dengan tegangan standar 24 VDC. Sedangkan terminal keluaran Y91 memiliki nilai persentase error tegangan sebesar 1,31% dengan tegangan standar 220 VAC. Dalam pengujian kinerja keseluruhan sistem bekerja normal sesuai dengan program PLC yang telah dibuat.

Abstract

Tracking Conveyor in this packaging is a system whose mechanics work to move an item that is on the conveyor from one place to another, basically this conveyor is widely used in the industrial world which is used for the transportation of very large goods. In order to achieve a large number of products to be produced, a fairly good and efficient movement is needed in order to achieve the production target, at this time there is still a lot that is still relatively manual carried out by human labor, while the movement to move goods quickly requires tools to move products to other places. in the box. This study aims to produce a conveyor tracking system in automatic packaging based on AU (Arduino Uno) using an ultrasonic sensor SRF04 and a photodiode sensor. The method used is a quantitative type method, which is a research method that uses numerical values, this type of research has many approaches that use numerical values, ranging from data collection and display of research results. With the above shortcomings, the authors encourage research and development of the use of appropriate and efficient technology, by combining ultrasonic sensors and photodiode sensors with conveyors. The result of this research is the sensor combination with the addition of a photodiode sensor combination to detect the presence of objects that have been applied to run the conveyor. In running this conveyor, two sensor requirements must be met, namely the distance to the object with the ultrasonic sensor should not be less than 5 cm and not more than 11 cm. The second requirement is that the distance between the object and the photodiode sensor should not be more than 11 cm. If both conditions are met, the conveyor will run.

Abstract

The need for telecommunications technology requires fast data transfer and increasing capacity. Therefore, telecommunications technology continues to be developed by creating transmitter and receiver devices that can work at Ultra-Wideband (UWB) frequencies. This study aims to design a coplanar Vivaldi antenna with a fractal structure so that the performance of the antenna radiation pattern can increase to apply UWB frequency. The conventional coplanar Vivaldi antenna, model-A, and Model-B fractal antennas are designed to see the performance of return loss values less than -10 dB, VSWR less than 2, and working frequency of 2-10 GHz. The fractal model is created with a circular repeating structure given at the edges of the antenna patch. From the simulation results, the main lobe value of the conventional Coplanar Vivaldi antenna was 5.21 dBi, the model-A fractal was 7.02 dBi, and the Model-B fractal was 7.84 dBi. The order of the best sidelobe performance at a frequency of 6 GHz is obtained for the model-A fractal of -9 dB. Beamwidth of 46 degrees and the best main lobe direction of 0 degrees is obtained for fractal model-B. By adding a fractal structure, the lobe magnitude/directivity, sidelobe level, beamwidth, and main lobe direction can be improved

Abstract

IEEE 802.15.4 is one of the standards of the Wireless Sensor Network (WSN) which is at the Medium Access Control (MAC) layer. IEEE 802.15.4 is also technology and protocol within a computer network that can connect all device quickly, has a large capacity and low power consumption. The challenge of Wireless Sensor Network is how to improve the Wireless Sensor Network network performance matrix (goodput, bandwidth utilization, and energy consumption) both in the Contention Access Period (CAP) and in the Contention Free Period (CFP) based on the IEEE 802.15.4 standard. This research is an analysis combination of adjustment delay and slot duration methods to increase goodput, bandwidth utilization and reduce energy consumption in Wireless Sensor Networks in the allocation guaranteed  time slots on fixed data simulated using Castalia Simulator software. The problem of this research is whether the combination method can improve the performance matrix of Wireless Sensor Networks on fixed data compared to other methods (SUDAS, ADES, IEEE 802.15.4 Standard). This reserch it aims to determine the performance matrix of combination methods is when compared to other methods (Superframe Duration Adjustment Scheme (SUDAS), Adjustment Delay Scheme (ADES), IEEE 802.15.4 standard) using quantitative approach research methods. Based on the data obtained, the goodput of the combined method increased by 10%, 416%, and 513% respectively compared to the SUDAS method, ADES method, and IEEE 802.15.4 standards. Bandwidth utilization of the combination methods increased by 0.025, 0.223 and 0.232, respectively compared to the SUDAS method, the ADES method, and the IEEE 802.15.4 standard. And the consumption of the combination methods are respectively reduced by 1.02%, 8.72% and 9.08% compared to the SUDAS, ADES and IEEE 802.15.4 standards. With the combination method of delay adjustment and slot duration it is able to optimize the performance of the Wireless Sensor Network compared to other methods.

Abstract

Abstract – In this work an integration of photo voltaic (pv) array connected to dc-dc buck converter will be introduce , this kind of converter play an important role for regulating dc voltage supplied from pv , it reduce the value of voltage according to loads .A separately excited dc motor will be connected to the system as a load , where this motor may exposed to variation in load conditions .PI controller presented as a solution to overcome the changing in load condition , by varying the voltage value it can regulate the motor speed under different sudden change load. (PID) considered a best choice for control circuit in nonlinear system like drive system. the goal of using it derived from adjusting the input voltage to converter under acceptable values. this work proved that using (PI) offering a better performance rather than traditional PID controller in such nonlinear system by enhancing its efficiency and reliability .
