Sistem Kompresi Data Logging pada Gateway Orange Pi 3 Menggunakan Metode GZIP

Abstract

Smart farming is a breakthrough developed to increase rice production. Smart farming refers to the use of IoT technology to log environmental condition in agricultural area. Through smart farming, data can be stored in the Orange Pi 3 gateway, then sent directly to the central government. However, smart farming produces increasingly large data over time. Due to time-series nature, 302,4 MB of data from 25 nodes can be generated over 1 week. The increasing data size causes wastage of bandwidth and increases of latency in sending the data logging to the warehouse. System implements GZIP before the logging data dump is sent to the warehouse. The GZIP method is compared with BZIP2 to determine its effectiveness. As the result, GZIP has an average compression ratio of 5.164, lower than BZIP2’s 7.426. The average percentage of storage saving of GZIP method is 86,5%, lower than BZIP2’s 86.5%. BZIP2 excels in the transfer time parameter. BZIP2 reduces the transfer time to 39.53 seconds. 30.6% lower than the GZIP treatment and 82.8% lower than the uncompressed treatment. Finally, system testing using load testing shows that the built system can handle up to 100 virtual users with HTTP request durations below 1 second. CPU usage is successfully maintained below 60%.
