ABSTRACT This study designed a high-voltage plasma generator using two flyback transformers with a ratio of 1:75 and a half-bridge inverter topology using a MOSFET as a switching device. The MOSFET was controlled by the control circuit IC 4047CD and it was connected to a 12 Volt dc. This inverter was connected to the flyback transformer to produce a high voltage. The high-voltage side of …
ABSTRACT The fifth-generation (5G) telecommunications technology has been implemented in Indonesia in June 2021. Its implementation is only limited to certain urban areas and does not cover the entire territory of Indonesia. Therefore, to support optimal results when implemented in Pekanbaru City, 38 GHz channel modeling needs to be done. The 38 GHz frequency is one of the recommended fre…
ABSTRACT Signal frequency detection is a process both analog and digital for various applications such as telemetry, telecommunications, security codes and remote control, in signal measurement the role of frequency measurement is very important. The applications and technologies that depend on frequency and timeliness include wired and wireless networks, power grids, radio navigation sys…
ABSTRACK Stroke is a neurological emergency, the morbidity is increasing from year to year. According to the World Health Organization, 15 million people suffer a stroke worldwide every year. Post-stroke patients with disabilities will find it difficult to carry out daily activities, especially in communicating with other people. Therefore, a communication tool for post-stroke patients was…
ABSTRACT Village letter creation is one form of village government service to the village residents. Village letter creation in Terbangiang Village is made by village residents that would visit the village office during working hours, then village officials would make a letter using Microsoft Word. Village letter creation in Terbangiang Village are still not optimal due to the relatively l…
ABSTRACT Chicken eggs can be hatched in two ways namely, incubated by a hen directly and by using a created egg hatching machine. The egg hatching machine replaces role of the hen in egg incubation process. Checking hatching machines manually by checking the stabilities of temperature and humidity in the hatching room one by one, cause temperature and humidity instabilities to be a problem…
ABSTRACT The increasing number of vehicles per year causes problems not only pollution but also congestion and traffic accident which continue to increase every year. So we need a system that can help reduce congestion and accidents such as Intelligent Transportation System (ITS). With the increase in information technology, especially computer networks and the internet, researchers in thi…
ABSTRACT Scheduling is one of the activities routinely carried out before students fill out the Study Plan Card (KRS). The main components in scheduling are students, lecturers, room, time and courses. So far, the scheduling in the Electrical Engineering Department actually uses computers, but it has not been used optimally. Schedule arrangement in the Department of Electrical Engineering …
ABSTRACT Education is something that helps the progress of the nation. Assessment is a process for making decisions using information from measuring learning outcomes. One of the problems at SMPN 01 Sungai Mandau, the assessment was done using paper, so there were many mistakes. This problem can be overcome by creating an information system that can help the assessment process to be faster…

The goal of a major concentration is to help students focus on the major or study based on their potential. University of Riau, Informatics Engineering Study Program has three including study concentrations there are Computing and Vision Intelligence (KCV), Software Eng…
ABSTRACT The development of modern technology today has made the industry carry out various innovations, one of which is in the field of digital image processing, especially in the biometrics field, such as facial recognition, facial recognition applications that can be implemented in various fields, for example room security systems for access to room doors. This research case study was c…
ABSTRACT Fossil resources are not a sustainable option for the future. The use of fossil energy sources needs to be reduced and replaced by unlimited energy resources. Solar energy is one of the alternative energy sources with Solar Power Plants (PLTS) because of its unlimited availability. PLTS with a rooftop PV system has the advantage of being the top location of a building and maximizi…
ABSTRACT Solar cells as one of the new renewable energy sources have an important role in meeting energy needs. For this reason, solar cells are used as an alternative source of electricity generation, be it off-grid or on-grid. The study presents the steps of the converter circuit simulation on a microgrid system with a solar cell source. The capacity of the solar cell to be simulated is …
ABSTRACT In this modern era, the watering system or irrigation is an important factor in agriculture and plantations. The serious threat faced by conventional farmers is the decreasing availability of water due to the prolonged dry season. This dry season can cause drought so that agricultural production can be reduced. Therefore, proper water management efforts are needed, especially in i…
ABSTARCT Humanoid robot itself is a robot that has human-like characteristics. Starting from the physical structure in general humanoid robots have a head, two hands, two legs, but there are some humanoid robots that are very humanoid such as having a waist to the upper body or even a face. The purpose of this study is to allow the robot to move steadily and balancedly according to the wil…
ABSTRACT The development of applied science and technology, especially in industry, can have both positive and negative effects. One of the negative effects is the higher pollution in soil, water and air. In order to overcame one of the problems, the use of ozone has now been widely applied in various fields, for example as a disinfectant for drinking water treatment, disinfecting germs, s…
ABSTRACT The rapid development of technology today and the many busy people encourage people to think they can work effectively and efficiently.
