Use of Aquatic Animal Purchasing Documents (APD) for Shrimp Famers in Nakhon Pathom Province

Abstract

This study aimed to investigate the use of the Aquatic Animal Purchase Document (APD) application among shrimp farmers in Nakhon Pathom Province. The research examined farmers’ socioeconomic characteristics, usage conditions, levels of knowledge, and opinions regarding the APD application. The sample consisted of 202 shrimp farmers in Nakhon Pathom Province in 2024. Data were collected using a questionnaire and analyzed using frequency, percentage, mean, t-test, and F-test. Pairwise comparisons of mean differences for the dependent variables were conducted using the LSD method. The findings revealed that most respondents were male (60.40%), with an average age of 48.44 years, and had completed upper secondary education (41.58%). A majority reported a high level of knowledge regarding the APD application (70.30%) and expressed an overall high level of opinion toward its use (mean score = 2.73). The highest-rated aspect was perceived benefits, followed by data quality, service quality, and system quality, respectively. Most farmers used smartphones to access the application. Hypothesis testing showed that differences in experience with information technology, shrimp production volume, income from shrimp farming, training participation, exposure to interpersonal and activity-based media, frequency of application use, type of sales, internet signal quality, and knowledge level of the APD application were significantly associated with differences in opinions toward the use of the APD application at the 0.01 and 0.05 levels of statistical significance.
