PERBANDINGAN SSE (SERVER SENT EVENT) & WEBSOCKET UNTUK INTEGRASI PADA SISTEM SELF CHECKOUT BERBASIS WEBSITE & MODULE RFID (RADIO FREQUENCY IDENTIFICATION)

COMPARISON OF SSE (SERVER SENT EVENT) & WEBSOCKET FOR INTEGRATION IN WEBSITE BASED SELF CHECKOUT SYSTEM & RFID MODULE (RADIO FREQUENCY IDENTIFICATION)

Penelitian ini mengkaji dua protokol komunikasi data, WebSocket dan Server Sent Event (SSE), dalam mengintegrasikan sistem website dengan perangkat RFID. Berdasarkan uji coba yang sudah dilakukan menunjukkan Websocket lebih unggul daripada Server Sent Event (SSE) dengan delay waktu 3.5 - 4.2 miliseconds dengan SSE 4.1 - 5.2 miliseconds. Sedangkan untuk penggunaan memori websocket menggunakan sekitar 210 – 340K dan SSE menggunakan 208-260K memori. Akan tetapi dengan mempertimbangkan Keunggulan websocket dalam komunikasi nya yang mendukung dua arah atau full duplex, juga mendukung format data yang lebih banyak daripada SSE yang hanya mendukung text atau tipe data String. Bisa disimpulkan dalam penelitian ini protokol komunikasi untuk integrasi antara RFID dengan aplikasi berbasis website, websocket lebih unggul dalam Delay dan beberapa aspek lain dibandingkan dengan Server Sent Event.

The advancement of technology, particularly in system and information fields, has enabled the digitalization and automation of various aspects of life, including the retail industry through the adoption of Self Checkout Systems. These systems utilize RFID (Radio Frequency Identification) technology to support cashier-less transactions. RFID facilitates automatic wireless data identification and capture through its main components: tags and readers. However, integrating web applications with RFID devices poses challenges, especially in real-time data communication. This study examines two data communication protocols, WebSocket and Server Sent Event (SSE), for integrating web systems with RFID devices. WebSocket offers a fast and efficient communication channel with a single connection, while SSE is more memory-efficient for event-based communication. The study compares the speed of data transmission and reception, as well as memory and bandwidth usage of both protocols, to determine the most effective protocol for a self-checkout system.
