Sistem Otomasi Mesin Tempat Parkir Mobil Bawah Tanah Dengan Menggunakan Programmable Logic Controller

Nowadays, number of cars increases more and more. This causes increase in the need of park area for the cars meanwhile there is limited area that can be used as park area for cars. Therefore, this paper describes about design of automatic car parking system, which places underground. This automatic car parking miniature model has 3 levels and each level can store 24 cars. This automatic car parking model is designed by using several actuators like AC motor, stepper motor, pneumatic system and several sensors like photoelectric and limit switch. Programmable logic Controller (PLC) is used as the controller, which controls all hardware. Experiment is done by running the automatic car parking system and experimental results show that the system can run well

Pengaturan Berat Total Material Yang Keluar Dari Weight Feeder Conveyor Dengan Menggunakan Kontrol Logika Fuzzy

This paper describes about a fuzzy logic control's application on weight feeder conveyor. The plant represented by a third order transfer function. The designed fuzzy logic control had single input and single output. The crisp input of fuzzy logic control was an error signal and the crisp output was a speed of motor. The system was tested by a computer simulation using Matlab. Experiment results showed that fuzzy logic control could work well. The best rise time and settling time achieved by the system were 4 and 6 seconds respectively

Sistem Monitoring Keamanan Menggunakan PLC FESTO

This paper describes a security monitoring system using FEC FC-20 FESTO PLC. The PLC would get the data from security sensors. Personal Computer (PC) would take this data through the serial port and then, PC processed that data and displayed it on PC monitor. Data in PC was processed and programmed by using Visual Basic 6 language program. The system was tested to monitor the security sensor such as status of the alarm button. PC could record alarm status and its history from sensors perfectly. The system was implemented and tested in PT FESTO Surabaya

Disain Dan Implementasi Modul Akuisisi Data Sebagai Alternatif Modul DAQ LabVIEW

This paper describes about an alternative module of data acquisition system (DAS), which can be accessed by LabVIEW. The advantage of this DAS module is inexpensive and it has good performance as well as module used in industrial control system. This DAS module is controlled by ATmega64 AVR microcontroller, which will communicate with the LabVIEW by using bidirectional serial communication. This DAS module has 8-bit digital input, 8-bit digital output, 8 channel analog inputs, 2 channel analog outputs. Voltage levels of digital input are 0 – 5 V and 0 – 24 V. The digital output of this module is an open collector terminal with “low” level voltage of 0.276 V. Analog input of this DAS module has three ranges. They are 1 – 5 V with average error of 14.47 mV, 0 – 10 V with average error of 72.34 mV, and 4 – 20 mA with average error of 0.037 mA. Range of analog output of this module is 0 – 10 V with average error of 16.2 mV. This DAS module is not designed for applications that need high accuracy of time

Mesin Bor Otomatis Dengan Menggunakan Kamera Untuk Mendeteksi Koordinat Bor

This paper describes about automatic drilling machine used to drill pad and via in Printed Circuit Board (PCB). The automatic drilling machine used camera as the sensor to detect coordinates of pad and via in PCB. This system used several methods of image processing like threshold, grayscale, and fillrect to detect the pad and via coordinates. This processes result the pad and via coordinates in pixels, then, these coordinates would be converted to millimeters in order to perform the drilling process. The automatic drilling machine used two stepper motors to perform the movement of X-axis and Y-axis. The machine also used two DC motors for the movement of Z-axis and drilling motor. The movement of each axis was designed by using the thread of a screw in order to achieve the precision movement. Experiment results show that average errors of the X-axis and Y-axis movement are 0.275 mm and 0.283 mm respectively. The system also could detect correctly all pad and via in PCB

Pencarian Rute Optimum Menggunakan Algoritma Genetika

Genetic algorithm can be used to solve optimation problems, such as for finding optimal route, which may be influenced by many internal conditions. In this paper, genetic algorithm was implemented to search optimal route from the start point to the destination point. Genetic algorithm system was designed by using bit string - chromosome representation, thus the mutation used was bit mutation. The selection method used was roulette wheel, elitism and hybrid selection between roulette wheel and elitism. There were two kind of crossover points used - one and two cut point crossover. From the experiments, we could conclude that the genetic algorithm system design worked well and solved the optimation problems

Remote Fuzzy Logic Control System for a DC Motor Speed Control

This paper will discuss about DC motor speed control based on fuzzy logic control system implemented on Linux operating system. This fuzzy logic control system can be designed and controlled from remote area i.e. any personal computer, which use TCP/IP network and http protocol. Range of DC motor speed which is controlled is 800-2400 RPM. Software is designed by using C language and Perl. Experiments were done for testing speed of fuzzy logic control process in any server type and condition, and also the experiments were done for testing the DC motor speed control system in various setting point. The results show that speeds of fuzzy logic control for AMD K6-2 400 MHz server with 224 MB memory and Pentium 120 MHz with 32 MB memory are 5.8 ms and 16.8 ms respectively. This system had been tested from local computer and remote computer at setting point 800 RPM, 1600 RPM and 2400 RPM for 90 seconds and system can control speed of DC motor well. The server computer which has light processes, takes 0.8929 second sampling time and server computer which has heavy processes takes 0.9646 second sampling time

Mesin Printer Huruf Braille Menggunakan Mikrokontroler MCS-51

YPAB (Institution for Blind Children) used manual typewriter to print Braille characters. If they want to print many copies, they will type it many times. It's not efficient. To upgrade this efficiency, they need a Braille printing machine which can make many copies in once type. The designed Braille printing machine consists of personal computer (PC), microcontroller MCS 51 and mechanic system. PC is used for typing, editing and converting to Braille characters. The experiment result showed that Braille printing machine using microcontroller MCS 51 could print many copy of Braille characters relief in once type. Speed of this printer is about 30 minute/ page while the paper size are 21,5 x 30 cm and there are 552 Braille character
