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

The type of insulation gases that are usually used in the power circuit breaker (circuit breaker) is the sulfur hexafluoride (SF6) gas, nitrogen (N2) and carbon dioxide (CO2). Most of the electric power systems are using insulating materials such as sulfur hexafluoride (SF6). Sulfur hexafluoride gas (SF6) has a higher dielectric strength than the air. However, Sulfur hexafluoride (SF6) gas is not friendly environmentally and very impact on global warming. The purpose of this study was to test the breakdown voltage of nitrogen gas (N2) (more friendly environmental) as alternative insulation of sulfur hexafluoride (SF6) gas. This study was used sphere and needle electrodes with a distance of 0.5-2 cm and a pressure of 1-4 bar; it was tested for 20 times. From the test results, it obtained that the breakdown voltage of sphere electrodes is more significant than the needle electrodes. Sphere and needle electrodes with a distance of 2 cm and a pressure of 4 bar have a most excellent value of breakdown voltage at the voltage of 140 kV and 79 kV, respectively.

Abstract

Inverter adalah sumber catu daya listrik arus bolak balik yang diperoleh dari hasil pencincangan sumber arus searah, disisi keluaran mengandung harmonisa, akibatnya kemampuan kapasitas daya yang dirancang menurun. Untuk mengoptimalkan kapasitas daya dalam rancangan yang memenuhi spesifikasi 660 volt ampere, maka pada saat merancang kapasitas daya yang diinginkan  daya fundamental ditambahkan dengan daya yang diakibatkan oleh harmonisa.. Penentuan parameter komponen perancangan catu daya yang dirancangan menggunakan kapasitas daya fundamental dan akibat harmonisa sebesar 886,528 volt ampere, maka dipilihn alat untuk proses switching transistor daya TIP 3055. Proses pencincangan sinyal menggunakan pembangkit osilator astable dengan frekuensi 50 Hz. Sinyal dari pembangkit pulsa astable belum mampu untuk mendriver transistor daya, sehingga diperlukan driver menggunakan BD 438 dan TIP 41. Dari hasil pengujian yang telah dilakukan daya yang rancang mampu melayani  sesuai beban  nominalnya, dan regulasi tegangan keluaran arus bolak balik yang dihasilkan 9,62 %. Dari hasil pengujian tersebut peralatan yang dirancang dinyatakan valid, maksudnya hasil rancangan dan pembuatan peralatan inverter  masih memenuhi sesuai spesifikasi jatuh tegangan ≤ 10%.

Abstract

Efforts and strategies have been done both by the providers of electrical energy and the government to handle the increase in electricity demand.  However, there has been no satisfactory result. The government has set a major policy on energy management, namely conservation and energy diversification in order to reduce dependence on non-renewable energy sources and utilize renewable energy available in areas where power plants will be built to meet the growing demand for electricity. Riau Province in addition to located in tropical climates and many of its areas are on the coast that its existence is very far for affordable network of PLN electricity, therefore the provision of solar power plant is one appropriate alternative, to meet the needs of electrical energy for the needs of the population. While the output voltage generated by solar cells is not constant, but it depends on the natural conditions that at any time vary the intensity of sunlight, so that the output voltage of the solar cell is also not constant and varies throughout the daytime. In general, commercial equipment has specification limits for ± 10% voltage variation. Disturbances such as voltage varization, if not handled seriously can cause damage to consumer electrical equipment, in addition to the use of electrical energy, in the form of varying output voltage resulting in expensive cost. To overcome the problem of voltage variations produced solar cell can be used prototype dc to dc converter using boost converter technology, which  automatically  adjust  the  output  voltage  according  to  the  desired  voltage.Designing  DC  to  DC Converters To Stabilize Solar Cell Outputs Using Boost Converter Technology has been tested for performance through the output voltage of a 100 WP solar cell panel whose values vary from 13.5 volts to 20.8 volts as a boost converter input and produce a regulated output voltage 24 volt. Based on the results of prototype testi ng dc to dc converter using booast converter technology that has been designed to produce a voltage regulated voltage of 24 volts direct current declared valid. The valid intent here because the output voltage is still dirange 24 volts ± 10%.

Abstract

This paper presents a novel automatic sliding gate system with IoT capability enabling it to be controlled through the Internet using a smartphone. The system is built on three main parts: sliding gate opener (SGO) with its driving mechanism, electronic control unit (ECU), and an Android smartphone with application software to communicate with the ECU. The SGO is driven by a 12-pole permanent-split-capacitor (PSC) motor coupled with speed reducer gearbox and uses a rack-pinion power transmission. The ECU, which is based on two microcontroller modules working in  a cascade arrangement, controls the movement of the PSC motor in either forward or reverse rotation according to the information gained from a set of mechanical switches, inductive proximity sensors, and commands from the smartphone. The first microcontroller module is an Arduino UNO, functions to control the operation of PSC motor. The second is an ESP32 NodeMCU rolling as a communication controller between the ECU and smartphone. The SGO can also be controlled locally at the gate site by using a set of mechanical switches mounted on the control panel of the sliding gate system. The sliding gate system employs two inductive proximity sensors installed at the ends of the SGO movement to give information to the Arduino to stop the motor automatically as the SGO approaches the sensor position. The functional test has been conducted on the sliding gate system and the results show that the SGO movement can be controlled locally through pushbutton switches and remotely using an Android smartphone.

Abstract

Ada banyak usaha kuliner bergerak di Pekanbaru yang menggunakan lampu minyak tanah (lampu petromaks) untuk pencahayaan gerobak dorong mereka. 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 kuliner bergerak di berbagai tempat. Artikel ini melaporkan kegiatan pengabdian masyarakat yang dilaksanakan di Kecamatan Binawidya, Pekanbaru, Provinsi Riau, yaitu pengadaan lampu LED bertenaga baterai akumulator beserta  alat pengisian muatan baterai (battery charger) menggunakan listrik PLN, untuk mensubstitusi lampu petromaks. Metode pelaksanaan pengabdian masyarakat mencakup perancangan, pembuatan dan pengujian lampu LED dan battery charger, penyerahannya kepada mitra, dan evaluasi penggunaan lampu LED bertenaga baterai akumulator oleh mitra. Kami telah mengevaluasi mitra untuk mengetahui dampak penggunaan teknologi battery charger dan lampu LED bertenaga baterai terhadap usaha kuliner bergerak mitra. Hasil evaluasi menunjukkan bahwa mitra telah menggunakan lampu LED bertenaga baterai untuk berjualan sate di malam hari, dan menggunakan battery charger untuk mengisi ulang muatan baterai di siang hari. Dengan menggunakan peralatan yang kami hibahkan, mitra telah beralih dari penggunaan lampu petromaks ke lampu LED, sehingga dapat menghemat biaya operasional sebesar Rp 450.000 tiap bulan.
