Abstract

Air is very important for the survival of living things, air quality will affect the state of human health. At present air quality is only monitored by KLH (Ministry of Environment) of Riau Province, with monitoring points only 1-3 points per city / regency in Riau. The frequent occurrence of forest fires in Riau, causing air quality to deteriorate rapidly so it requires a tool that can monitor air quality and improve air quality to maintain human health. Therefore, the authors conducted research and design of tools to be able to monitor air quality (CO gas levels) and improve air quality in the room. The workings of this monitoring device are MQ-7 gas sensors measuring CO (carbon monoxide) gas levels, where the data is then processed and sent through a wi-fi network using ESP8266 and the data is also used as a reference for control the air purifier in the room. The results of this monitoring are shared using Google Spreadsheets by e-mail to the people whom concerned. The MQ-7 sensor works best in the range of 50-150 ppm carbon monoxide gas with a deviation of 14 ppm from a calibrated multi gas detector. Keywords: Monitoring, Gas CO, ESP8266, MQ-7, Google Sheets, Air quality, Air Purifier.

Abstract

Nowadays, 4G cellular service has become a basic need especially for campus communities. Information exchange and learning processes often utilize technology in this service. Block 6, floor 2 of the PCR campus consists of 2 lecturer rooms, 4 laboratories, 1 meeting room and 1 research room. Of course, this is one of the spots in PCR where 4G service is needed. Of the several 4G service providers in Indonesia, Telkomsel is the operator that has the most customers. 4G network performance can be seen in several parameters such as RSRP, RSRQ, CSFB, Throughput and SINR. These parameters are obtained through a process called Drive Test (DT). Drive Tests carried out by walking in closed areas such as inside buildings, malls, and such are called Walktests (Indoor Drive Tests). This research is focused on observing only one parameter, namely throughput. From this research, the maximum throughput value for Telkomsel's 4G network in Block 6, Floor 2, PCR Campus at the time of measurement (July 13 2023 at 16.43 WIB) was 2.18 Mbps. So when compared with the KPI set by Telkomsel, the throughput value in block 6, floor 2 of the PCR campus is in the "fairly good" category. Keywords: 4G, Drive Test, Throughput
