An Application of QR Code to Manage Plant Information in Kuan Khao Wang Literature Botanical Garden

Abstract

This research has two objectives: (1) to develop an application for managing plant information in a botanical garden using QR Code, and (2) to study the satisfaction with the application for managing plant information in a botanical garden using QR Code. The application was developed following the SDLC process, using the Ionic Framework and the Firebase cloud system for data storage. The application has two user types : administrator and visitor. Only administrator can edit, add, or delete the plant information. However, both administrator and visitor have access to the navigation menu, QR code scanning, plant information view, user manual and botanical garden’s history. The research sample consisted of 120 visitors who visited the botanical garden. They were selected using random sampling. The research tools were the developed application and the questionnaire. The questionnaire was reviewed by experts, resulting in the confidence level of 0.86. The statistics used in the data analysis included the arithmetic mean ( ) and the standard deviation (SD).  The results of the research revealed that (1) the visitors were able to use the application to visit the botanic garden independently. The personnel of the botanic garden were able to effectively manage the plant information through the application.  (2) The visitors who visited the botanical garden were overall satisfied on the application at the highest level ( = 4.55). When considering each aspect, it was found that User Interface Design had a high level of satisfaction ( = 4.40). Application's performance in terms of navigating to the tree was evaluated through the tree navigator test 50 times. It was found that the navigation was correct, although there was a discrepancy between the location of the application user and the actual tree with an average distance of 2.24 meters.
