Analysis of characteristic of pesticide residue sensor cards for fruits and vegetables affectiving user satisfaction in Bangkok

Abstract

This study aims to explore personal background information and analyze the characteristics of a pesticide residue sensor card for detecting chemical residues in fruits and vegetables among users in Bangkok. Data was collected from 400 consumers of fruits and vegetables in Bangkok using a questionnaire. The results revealed that the majority of respondents were female (59.50 %), with an average age of 27.45 years. Most respondents held a bachelor’s degree (84.30 %). The majority purchased fruits and vegetables from fresh markets or street markets (88.90 %) and spent no more than 1,000 baht per month on produce (82.8%). Furthermore, 77.80 % of participants preferred a test kit priced below 800 baht, 89 % preferred a portable version, and 69 % wanted the test kit to be reusable. Additionally, most respondents wanted the test kit to be able to detect pesticide residues in Chinese kale (82.90 %) and oranges (70.10 %). Regarding the analysis of the sensor card’s features using Kano’s model with 27 attributes, the results revealed two categories: Group I (Indifferent), which consisted of 18 attributes that did not significantly influence user satisfaction, and Group A (Attractive), which consisted of 9 attributes that were highly appealing to users. This suggests that users valued the visual appeal of the sensor card, and the key features that would attract users included: the use of colors, images, and symbols at each step of the process; the ability to adjust font size for clarity; clear color differentiation between the test solution and the test tube for each type; and for the accompanying application, ease of installation, a minimal number of steps to access the app, and the clear display of the pesticide residue concentration detected.
