Abstract

Analysis of the performance of the LTE network with WiFi networks was carried out in the G5 building of the Faculty of Engineering, University of Muhammadiyah Yogyakarta, which is the building of the Faculty of Engineering Laboratory. This research was conducted by comparing the LTE network with indoor or indoor WiFi networks, measuring these two networks using the Network Analyzer and Wifi Analyzer application to obtain information on signal quality data based on KPI and TIPHON standardization, which shows RSRP, RSRQ, and Throughput values through measurement using the Network Analyzer and Wifi Analyzer application. From the results of research that has been done shows that the G5 building has a WiFi internet network that is superior to the LTE internet network. The overall condition of the Wifi network is in very good condition and is stable for each floor. While the LTE network even though it has increased conditions on the second floor but overall is in a bad condition to normal. The LTE network has an RSRP value with an average of -143 dBm, while a WiFi network with an average of -90 dBm. Then the LTE network has an RSRQ value with an average of -13 dBm, while the Wifi network with an average of -15 dBm. For LTE network throughput it has an average max. ping by 50.9 ms and min. ping is 864.5 ms, while WiFi networks have max average. ping by 24.3 ms and min. ping of 144.5 ms. From the results of these data show that the G5 Building has a good WiFi network and is superior to the LTE network.

Abstract

Currently, conventional motorcycles that utilize hazardous fossil fuels are expanding rapidly in Indonesia's major cities. Especially in campus environments, the increase in motorcycle usage has the potential to raise emissions of greenhouse gases and toxic microparticles. The green campus concept entails that campus living must implement low-emission energy efficiency, conserve resources, and enhance environmental quality by teaching its residents how to live a healthy lifestyle. However, limiting the number of motorcycles on campus is the main challenge, especially in Indonesia. To overcome this challenge, this study provides a design for the e-bike system that will be implemented at Universitas Muhammadiyah Yogyakarta (UMY). In addition, a solar power plant is integrated into the design to support the adoption of the zero-emission green energy concept on the campus. The design accommodates specifications for a 6 km radius surrounding the school, a two-day lifespan, and 100 electric bicycles. The experiment's findings indicate that the solar-powered e-bike design requires 99 solar panels with a capacity of 150 Wp, 9 SSCs with a capacity of 100 A, and three inverters with a capacity of 2,500 W. It is projected that this device will reduce exhaust emissions by 7.62 tons of CO2 per year once it is entirely operated.
