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

This paper presents the sliding gate opener system that android smartphones can remotely control using Bluetooth protocols. The gate opener is driven by a 12-pole single-phase induction motor of permanent-split-capacitor type (PSC motor) coupled with a worm gearbox and rack-pinion power transmission. The PSC motor installation is wired to rotate either forward or in the reverse direction by using a contactors arrangement controlled by the Arduino microcontroller module. Two limit switches are installed at the ends of the gate opener movement to inform the microcontroller to stop the motor automatically when the gate opener touches them. Moreover, the microcontroller module has been wired with Bluetooth transceiver HC-06 enabling it to communicate with other Bluetooth devices. The microcontroller module has been programmed so that the gate opener movement can be remotely governed from android smartphones and controlled at the site by operating a set of pushbutton switches mounted onto the control panel's door. The functional test has been conducted on the sliding gate opener system, and the result shows that the gate opener movement can successfully be controlled locally through operating pushbutton switches and remotely using an android smartphone with up to 8 meters.

Abstract

ABSTRAKArtikel ini memaparkan rancang bangun suatu alat pengisi muatan baterai (battery charger) kendaraan listrik jenis lithium-ion. Baterai yang digunakan berkapasitas 20-Ah dengan tegangan pengenal 48-V. Rangkaian battery charger menggunakan susunan kombinasi dari konverter AC-DC topologi penyearah satufasa jembatan dioda dan konverter DC-DC topologi jembatan-penuh yang dioperasikan pada frekuensi menengah (MF) yaitu sebesar 1 kHz. Rangkaian konverter jembatan-penuh dikendalikan oleh IC SG3526 yang mengatur lebar pulsa sinyal PWM yang diberikan kepada keempat MOSFET yang menyusun konverter tersebut. Karena dioperasikan pada frekuensi 1 kHz, konverter jembatan-penuh dapat menggunakan transformator yang intinya berbahan baja silikon berbentuk pelat tipis terlaminasi atau lebih dikenal dengan inti pelat E-I. Pengujian fungsional alat dilakukan dengan mengisi muatan baterai pada keadaan kapasitas awal 50% hingga penuh, menggunakan metode arus pengisian tetap sebesar 5-A. Hasil pengujian memperlihatkan bahwa diperlukan waktu 80 menit untuk mengisi baterai hingga penuh pada kondisi tersebut.Kata kunci: alat pengisi muatan baterai lithium-ion, kendaraan listrik, full-bridge DC-DC converter, frekuensi menengah, transformator inti baja silikon ABSTRACTThis manuscript describes the designing and making of a lithium-ion battery charger for battery electric vehicle applications. The battery has a capacity of 20-Ah with 48-V nominal voltage. The battery charger circuit uses the combination of an AC-DC converter in the form of a single-phase diode bridge rectifier and a full-bridge DC-DC converter, operating in medium frequency (MF) at 1 kHz. The full-bridge converter is controlled by a PWM controller SG3526 that sends its output to the 4 MOSFETs that built the converter. Due to operation at frequency of 1 kHz, the transformer’s core can use the laminated silicon steel sheet that is known as the E-I core. The battery is charged using the constant-current method by maintaining the charging current at a constant value. The functional test of the battery shows that by using 5-A constant current charging, the battery takes 80 minutes to its full condition from 50% capacity at the beginning.Keywords: lithium-ion battery charger, battery electric vehicles, medium frequency full-bridge DC-DC converter, silicon steel-core transformer

Abstract

Nelayan tangkap skala kecil pada umumnya menggunakan lampu minyak tanah (lampu petromaks) untuk menangkap ikan dengan teknik light fishing. Penggunaan minyak tanah saat ini sedang mengalami kendala ketersediaan, karena sejak tahun 2008, pemerintah telah membatasi penggunaan minyak tanah dan menggantinya dengan LPG. Kondisi ini telah berpengaruh buruk pada kelangsungan usaha nelayan tangkap. Artikel ini melaporkan kegiatan pengabdian masyarakat yang dilaksanakan di Kecamatan Tempuling, Kabupaten Indragiri Hilir, Provinsi Riau yaitu pengadaan lampu LED bertenaga baterai beserta alat pengisian muatan baterai menggunakan listrik tenaga surya, untuk mensubstitusi lampu petromaks. Panel surya dipasang pada suatu konstruksi yang dilengkapi roda, sehingga dapat dipindah-pindah dengan mudah. Karenanya peralatan ini dinamakan movable solar battery charger (MSBC). Metode pelaksanaan pengabdian masyarakat mencakup perancangan, pembuatan, dan pengujian MSBC, penyerahan MSBC kepada mitra, dan evaluasi penggunaan MSBC oleh mitra. Kami telah mengevaluasi mitra untuk mengetahui dampak penggunaan teknologi MSBC dan lampu LED bertenaga baterai terhadap usaha penangkapan ikannya. Hasil evaluasi menunjukkan bahwa mitra telah menggunakan lampu LED bertenaga baterai untuk menangkap ikan di malam hari, dan menggunakan MSBC untuk mengisi muatan baterai di siang hari. Dengan menggunakan MSBC, mitra telah beralih dari penggunaan lampu petromaks ke lampu LED, sehingga dapat menghemat biaya operasional sebesar Rp 180.000 tiap bulan.
