e-Canteen for the Smart Campus Application

Abstract

Nowadays in 4.0 industrial and digital economic era, all of the manual serving should be changed by the serving service which use a technology as the helping tools and applications to support the smart canteen in solving the problem of serving food and the queue for paying. Therefore, e-canteen web system with the Raspberry Pi as the sever is created, which can ordering directly through the table of customer without waiting for the waiter to bring the menu, and even for payment as well because the system is compactly designed to make it easier for cashier, waiters and even for chef in the kitchen in coordinating each other. The test is conducted by the support of the Apache JMeter software to do the testing of server ability in handling many clients based on the response time from server. The results show that Raspberry Pi 3 Model B with Ram 1 GB capacity able to handle numbers of threads (users) more than 150 users at the same time with response time value around 8 ms–17.6 ms and throughput value around 132.23 request/s. In parameter QoS testing, when using WiFi network in Raspberry and Wireless Network Adapter ARGtek ARG-1209 type, it is obtained that the index value is 3 with 87,5% percentage which means the QoS value in web access analysis when using the Raspberry WiFi network as well as the Wireless Network Adapter is in the good category.
