Abstract

The development of science and technology will increasingly have an impact on human life, especially electronic devices at home. In-home reservoirs, commonly, the owner of the water pump cannot detect the level of the water reservoir in his house due to no automation in the water pump. This study seeks to design a device that can control one water pump for filling three reservoirs, where the reservoir filling path will be regulated by a solenoid valve. It also aims to increase the efficiency of electrical energy in the water pump and be monitored by homeowners. The research was conducted at Yulihamri's rented house on Merak Sakti Road. In testing the measurement of electrical energy without using a control, the results obtained in the first reservoir of 1253.99 Wh, 2072.83 Wh, and 2136.27 Wh in the first, second, and third reservoirs, respectively. Meanwhile, in testing the measurement of electrical energy using the control system, the results obtained on all reservoirs in sequence are 1234.70 Wh, 1754.52 Wh, and 1644.12 Wh. The electric energy efficiency of the water pump after using the control system enhance by 15%. The contribution of this research is to reduce the use of excessive electrical energy due to the filling of water that exceeds the storage capacity so as to make it inefficient for the use of electrical energy as well as the water released. The research also limits the use of electrical energy at the end of the month, which makes this system more efficient compared to other systems.

Abstract

Media information has a very important role in efforts to attract prospective students to join. A website needs to be improved in the era of large technological developments. One of the new information media that utilizes the latest technology is a virtual tour. If you look at some of the previous ones, making a virtual tour can be made using panoramic photos made with image stitching techniques from many photos and can also use 3-dimensional engineering results. Both ways have their advantages and disadvantages. In this study, we will combine panoramic photos and 3D engineering to create a virtual tour of the Department of Electrical Engineering, Riau University. Virtual tour created using an equirectangular image base. There are 10 locations included in the virtual tour which four of them use panoramic photos and the remaining six places use 3D engineering. Four panoramic photos and six 3D-engineered equirectangular shapes are combined into one virtual tour. To validate the results of combining panoramic photos and 3D engineering into a virtual tour, user experience testing was conducted using a user experience questionnaire. User experience questionnaire was  distributed to 30 respondents. As a result, four scales are in the excellent category: attractiveness, dependability, stimulation, and novelty. Then two scales are included in the good category, namely perspicuity and efficiency, which get a value of 1.78. From the user experience perspective, virtual tours resulting from a combination of panoramic photos and 3D engineering in general can be considered very good. Then this combination of panoramic photos and 3D engineering can be used as a solution for virtual tour documentation if several locations are inadequate to document

Abstract

The global COVID-19 pandemic has significantly impacted the health and lives of people worldwide, with high numbers of cases and fatalities. Rapid and accurate diagnosis is crucially important. Radiographic imaging, particularly chest radiography (CXR), has been considered for diagnosing suspected COVID-19 patients. CXR images offers quick imaging, affordability, and wide accessibility, making it pivotal for screening. However, the scarcity of CXR images remains due to the pandemic's recent emergence. To address this scarcity, this study harnesses the capabilities of Deep Convolutional Generative Adversarial Networks (DCGAN). DCGAN is a convolution-based GAN approach, has the potential to alleviate the scarcity of CXR data by generating authentic-looking synthetic images. This study combines synthetic CXR images with real CXR images to bolster model performance, resulting in an Extended Dataset. Extended Dataset comprises 7,345 images, with 34.63% being original CXR images and 65.37% being synthetic images produced by DCGAN. Expanded Dataset then utilized to train three pre-trained models: ResNet50, EfficientNetV1, and EfficientNetV2. The outcomes are remarkable, showcasing considerable enhancement in detection accuracy. Especially for the EfficientNetV1 model, it takes the lead with an impressive accuracy of 99.21% after merely ten epochs, achieved within a brief training period of 6.18 minutes. This surpasses the prior accuracy of 98.43% observed when used the Original Dataset (without synthetic CXR images). Overall, this research offers a solution to mitigate the scarcity of synthetic CXR images for COVID-19 detection. For future endeavors, refining the quality of synthetic images stands as an area for exploration, enhancing the overall efficacy of this approach.

Abstract

QoS (Quality of Service) measurement of LTE (Long Term Evolution) networks is carried out using the Telkomsel provider. Measurements were made in Perawang, Riau at night. QoS measurements are carried out at Perawang to evaluate and monitor network quality in accessing vidio streaming services provided by the Telkomsel network in the Perawang, Riau. Measurements were aimed at 5 streaming applications, namely YouTube, RCTI+, Online Radio, Twitch, and Vidio. The reason 5 applications are used for QoS measurement is that these applications are popular applications used in the category of Vidio streaming applications. Measurements were carried out for 160 seconds. The measurement results will be analyzed for quality based on the TIPHON standard. The results were obtained by calculating the data that has been obtained by Wireshark. The data will be calculated using the existing equations. Twitch is the only application that has a value of four in the QoS parameter index category and has a QoS value with an excellent index category. 4 other applications have a QoS value with a good index category. This is due to the low value of the throughput index category. Online Radio and Vidio applications have an index category value of 0. YouTube and RCTI+ applications have a throughput index category value of 1 and 2 respectively. For jitter, packet loss, and delay values, 5 streaming applications have an excellent index category with a value of 4. The measurement results that have been obtained would be displayed in the form of tables and graphs.

Abstract

Based on the results of the research conducted, it can be concluded that the 5G network at Airport shows excellent performance in supporting the use of VoIP applications such as Instagram, WhatsApp, and Zoom. This is indicated by a consistent category 4 index on all measured parameters, namely throughput, packet loss, delay, and jitter. In terms of throughput, although there are variations between the three apps, all values are still sufficient to support voice and video calls with good quality. In fact, the lower throughput value on the Zoom app does not mean that the video call quality is poor, especially for one-on-one calls or with few participants. Furthermore, the absence of packet loss in all three applications indicates excellent connection stability. This is an important indicator showing that all the data sent and received by the apps made it to their destination without being lost midway, which is essential for ensuring clear voice and video quality. Meanwhile, very low delay and jitter indicate that data transmission is fast and consistent. This is especially important for real-time communications such as video calls, where delays or variations in the arrival time of data packets can disrupt call quality. Overall, the results of this study show that the 5G network at Airport is capable of supporting the use of VoIP applications with good quality. This is an important finding, given the importance of VoIP in everyday life, both for personal and professional communication. Therefore, this research hopes to make an important contribution in understanding and maximizing the potential of 5G network in supporting VoIP communication at Airport.

For the independence of coastal radar technology, the need for low cost RF amplifiers is a must.This paper presents simulation and realization of microstrip RF amplifier used RT/Duroid 5580 and matching stub technique worked at 9.3 GHz. This matching technique is effective for high frequency and to match the impedance with imaginer value. The active component of MGF2407A was chosen with DC fixed bias configuration. From simulation, the proposed RF amplifier has gain of 10.318 dB, S11 of -26 dB and S22 of -28 dB with P1dB compression at 11 dBm. However, during the measurement, the RF amplifier provides attenuation due to soldering, short circuit, and electro statis discharge effects. For other measured parameters met the standard requirements. This demonstrates the low success rate of realizing microstrip RF amplifiers for high frequencies.Keywords: coastal radar, power amplifier, matching stub, microstrip
