Abstract

Karena menghasilkan emisi gas karbonmonoksida (CO) yang bersifat racun, genset portabel harus diletakkan di luar ruangan dan tidak di dekat pintu, jendela atau ventilasi udara. Kondisi ini menyebabkan posisi genset portabel berjauhan dengan saklar pemindahnya. Oleh karena itu suatu sistem kendali pengasutan dari jarak jauh tanpa kabel diperlukan untuk mempermudah operator dalam mengoperasikan genset portabelnya, sehingga dia tidak perlu berada di dekat genset untuk menyalakan atau memadamkan gensetnya. Dalam penelitian ini telah diupayakan untuk membuat sistem kendali pengasutan genset portabel dari jarak jauh tanpa kabel yang dapat dipasangkan pada genset portabel berbahan bakar premium. Sistem yang dibangun terdiri atas unit pengendali jarak jauh yang berukuran dapat digenggam dan unit aktuator yang secara permanen terhubung secara listrik dengan genset yang dikendalikan. Komunikasi antara unit pengendali jarak jauh dan unit aktuator terjadi secara simpleks menggunakan gelombang radio pita ISM pada frekuensi 433,92 MHz. Sistem yang dibuat telah diimplementasikan untuk menyalakan dan memadamkan genset portabel YMW4500XE merk YAMAWA dan genset tersebut dapat dikendalikan sampai jarak 70 meter dan juga genset yang berada di dalam bangunan berlantai tiga dapat dikendalikan dari dalam dan luar bangunan.

Abstract

The availability of electrical energy is an important thing needed in everylife. To control if there is a power failure happened from the main supply (PLN) a device is needed, so that the reliability of the transmission system is maintained. This tool is known as the transfer switch the cam switch. When there is a disruption to the PLN electricity then the cam switch will automatically be moved to the generator supply, if the PLN electricity has improved then the cam switch is again moved to the PLN contact, and to move the cam switch is used an electric motor. In this research designed a stepper variable reluctance motor as a cam switch driver. Stepper variable reluctance motors are designed using magnet infolytica software with a combination of 6 stator poles and 4 rotor gears. The reluctance 6/4 stepper variable motor is expected to be able to drive the cam switch with a torque of 0.3 Nm and a 30-degree rotor step length. After being analyzed, it was obtained that the optimal dimension values with outer dimension of the stator 122 mm, inner diameter of the stator 72 mm, outer diameter of the rotor 71 mm and the machine length is 44.5 mm with 800 turns. The results of the analysis of the research obtained a machine torque value of 0.192 Nm. When the length of the machine is enlarged to 70 mm then the machine torque is 0.301 Nm, but the large flux density is 1.41 Tesla to 1.64 Tesla.Keywords : stepper variable reluctance motor, cam switch, software magnet infolytica

Abstract

Augmented Reality (AR) is a technology which combines the real world and virtual world, where users can feel the interaction between the two worlds. Marker Augmented reality or known as marker-based tracking technique uses a marker as media to display this technology. The marker is used as an object that contains images with unique patterns to identify each different object. Because it has a unique pattern, not any objects can be used as a marker. In Vuforia SDK, image recognition is done using a grayscale technique to search for angular features of the pixel image. If the image was taken directly using the camera in the old times in the form of Black and White (BNW), it has bad quality and most likely cannot be used as a marker because it has a few features. In BNW images taken directly from the camera, the Vuforia SDK detects only a few features in the image. This journal explains how the technique of making a BNW image into a marker can be detected by Augmented Reality Technology.

Abstract

Electricity supply from PLN network is not always continually available, there could be a blackout at any time. To anticipate such outages, it is necessary to design an automatic transfer switch between the main power source and the backup power. Therefore, it is necessary to develop the automatic transfer switch equipment, where mechanically formed by cam-switch which is driven directly by variable reluctance stepper motor with microcontroller ATMega8535. Automatic mode of operation is determined by stepper motor controlled by microcontroller ATMega8535 while manual mode is done by using grip handle attached to the rotor axis of variable reluctance stepper motor. The determination electricity supply of genset and PLN conditions is determined tolerance of ± 20% from 220 VAC standard voltage of PLN, this condition becomes the basis for moving the stepper variable reluctance motor with the angle-step position -300 for the supply of PLN (I) and +300 angle for generator (II) to move Cam-switch to supply the load. The testing design has done with the following result i.e. the variable reluctance stepper motor will rotate if fullfilled the 20% of tolerance to achieve for the uninterruptible load supply. The transition will take affect within 5 s.Keywords: Automatic transfer switch, Microcontroller ATMega8535, Variable reluctance stepper motor.

Abstract

Pada instalasi listrik, saklar pemindah berfungsi untuk memindahkan pasokan tenaga listrik dari jaringan utilitas (jaringan listrik PLN) ke sumber tenaga listrik cadangan seperti genset ketika pasokan tenaga listrik dari jaringan utilitas terputus. Saklar pemindah akan kembali ke posisi normalnya apabila pasokan tenaga listrik dari jaringan utilitas telah kembali pulih. Artikel ini memaparkan rancang bangun suatu saklar yang digerakkan oleh cam atau cam operatedswitch untuk digunakan sebagai saklar pemindah.Saklar pemindah mempunyai 3 posisi, posisi 0 atau posisi netral digunakan untuk membuka hubungan beban listrik dari jaringan listrik PLN dan dari genset, posisi I digunakan untuk menghubungkan beban listrik ke jaringan listrik PLN dan posisi II digunakan untuk menghubungkan beban listrik ke genset. Sudut kerja cam adalah ±30 derajat. Posisi I dicapai dengan menggerakkan cam 30 derajat berlawanan arah jarum jam dan posisi 0. Posisi II dicapai dengan menggerakkan cam 30 derajat searah jarum jam dari posisi 0. Limit switch digunakan sebagai saklar yang nantinya akan disentuh oleh cam. Apabila limit switch disentuh oleh cam, maka kontak dari limit switch akan menutup dan apabila cam tidak menyentuh limit switch, maka kontak limit switch akan terbuka.Cam nantinya akan digerakkan oleh motor stepping variable reluctance dengan panjang langkah 30 derajat.

Abstract

Battery is an alternative energy source and it is important for energy storage. Battery is often used as energy reserves but the energy in the battery is not able to maintain for longer time. Therefore the battery need to be recharged. This paper proposed a push-pull converter design which is supplied by PLN. In the push-pull converter design the output voltage is constantly in 14.1 volt value with the current of 2.16 ampere. The battery type that being used is sealed lead acid (SLA) which has a capacityof 7.2 Ah with a nominal voltage of 12 volt. The system was designed using MATLAB-Simulink software. The result of simulation shows in three scenarios in example the output of converter when the input fluctuation condition, the load of converter when the input steady state condition, then it connect to battery for charging purpose output of converter already in stable condition.Keywords : Push-pull Converter, Sealed Lead Acid Battery, MATLAB-Simulink

Abstract

This paper presents an attempt to design and make a rogowski coil together with its signal conditioning circuit for alternating current measurement. The induced voltage between rogowski coil ends is connected to active integrator circuit to yield voltage signal that is linear corresponding with the measured current. The output of integrator circuit is amplified its level before rectified using precision rectifier circuit. The output of precision rectifier is filtered using capacitor before connected to analog input port of ATMEGA8535 microcontroller. Microcontroller performs data acquisition of the signal, processes it and sends information of the rms value of the measured current to an LCD display. A test with 0.5 class moving-iron type amperemeter as a comparison shows that for measurement of alternating current from 0 to 5 amperes, the maximum value of error measurement is 2.5%.Keywords: rogowski coil, active integrator, precision rectifier, ATMEGA8535 microcontroller
