GERBANG LOGIKA BERBASIS PROGRAMMABLE LOGIC DEVICE (PLD)
Full text linkIn middle 1990, electronics industry had evolution in personal Computer, telephone cellular and high speed data communication equipment. To follow this development, electronics companies have designed and produce new product. One of these innovations is Programmable Logic Devices (PLD) technology. It is a technology to change function of IC digital logic using programming. Many of Programmable Logic Device (PLD) can be used to programming logic using single chip of integrated circuit (IC). Programmable Logic Devices (PLD) technology is applied using IC PAL 22V10 to design basic logic gate AND, OR, NOT and combinational logic gate NAND and NOR

PENGATURAN PARKIR KENDARAAN MASUK/KELUAR AREA PARKIR DAN MEMBANTU PENGEMUDI SAAT PARKIR BERBASIS MIKROKONTROLLER
Full text linkMany parking area still use manual system such as ticketing, parking position, etc. Nowadays, this system can be control easier using microcontroller. In this control system, infra red and photodiode are used to inform when car come and out to parking area. Another sensor, ultrasonic, is used to help driver to park the car safely. Alarm will warn the driver if the position of the car broke the limitation of safety range to park. In another hand, the empty parking areas are display in LCD and related with portal which opened when the empty parking area still available and close if it full automatically. Microcontroller is used to control sensor, LCD and porta
PENGATUR LAMPU LALU LINTAS SISTEM DIGITAL BERBASISKAN MIKROCONTROLER
Full text linktraffic light still uses analog system with discrete component. This technology has many disadvantages for example difficulty in maintenance and repair, display only to lamp without counter and no control for delay in normal hours or rush hours. These can be cause traffic jam and accident. To solve this problem, traffic light system is completed by digital system and buzzer using microcontroller AT89C51. The observation result to prototype at laboratory in Polytechnic State of Padang show this system can be implemented to real condition
RESTORASI CITRA MENGGUNAKAN JARINGAN SARAF TIRUAN (HOPFIELD)
Full text linkThe final goal of restoration is image improvement. In general, restoration to degradation modeling and implementation of invers process to get real image. Hopefield method in neural network restoration of image is done by parameters approximation in neural network modeling and reconstruction of degradation image to get real image. In this paper, this method is used image restoration which combines with Gaussian Blur, Uniform Blur and Gaussian Noise. The restoration process using this method take place really fast and suitable to defects restoration of recorder device which recognize the cause of defects and high process speed is needed
PERENCANAAN INVERTER PWM SATU FASA UNTUK PENGATURAN TEGANGAN OUTPUT PEMBANGKIT TENAGA ANGIN
Full text linkInverter as power circuit is used to change DC to AC voltage. In general, DC which can be changed by inverter is DC voltage with constant value, for example battery or accu. Inverter is design to changed non constant DC voltage which produced by wind power generator become constant ac voltage. In changing process from non constant DC voltage to constant AC voltage is controlled by microcontroller to simplify the design of inverter
PREDIKSI DISTORSI HARMONISA PADA UTILITY LISTRIK PERUMAHAN YANG DISEBABKAN OLEH BEBAN NONLINIER MENGGUNAKAN STATISTIK PERBANDINGAN LINIER
Full text linkLoads of electricity utility consists of linear loads and non linear loads. The non linear loads for example TV, personal computer, VCD player, microwave and fluorescent lamp using electronics ballast. Loads with non linear characteristics become harmonic current source to electricity utility. Condition prediction used statistic linear comparison based on load power to THDi (Distortion of Harmonic Current). Measurement result using power quality analyzer and etap 4.0 (Fluke 43B) find typical THDi. The calculation and measurement result of PF and THD to loads of electricity utility show the differences less than 5%. However power factor formulation and distortions of harmonic current is vali
KONTROL FREKUENSI DAN TEGANGAN GENERATOR MENGGUNAKAN METODE JARINGAN SYARAF TIRUAN
Full text linkThis paper discusses artificial neural network to controlling frequency and voltage generator using control system based – on diagonal recurrent neural network. Reference model for purpose controlling generator frequency and voltage i.e. at settling time 50 Hz and 380 V (line-to line) respectively. Observation shows that control system based-on diagonal recurrent neural network has good performance in the case of controlling frequency and voltage of plant generator
