Abstract

Background and Aim: This research aimed to 1) study the level of public participation in solid waste management in Phaya Thai District, Bangkok, and 2) compare gender, age, occupation, average monthly income, and length of residence in the area with their participation in solid waste management in Phaya Thai District, Bangkok.

Methodology: A quantitative study was conducted. The sample consisted of 400 residents aged 18 years and over in Phaya Thai District, Bangkok, using a simple random sampling technique. The data collection tool was a questionnaire. Statistics used for data analysis included frequency, percentage, mean, standard deviation, and one-way analysis of variance. The sample size used for the research was calculated using the Yamane formula. The research instrument was a questionnaire on public participation in solid waste management in Phaya Thai District, Bangkok, which was quality-checked and had a reliability of .96.

Results: 1. Residents in Phaya Thai District, Bangkok, had the highest level of overall participation in solid waste management (mean = 4.21). Participation in evaluation had the highest mean (mean = 4.58), followed by participation in decision-making, participation in implementation, and participation in benefit sharing, respectively. 2) A comparison of public participation in solid waste management in Phaya Thai District. Bangkok is classified by gender, age, education level, occupation, monthly income, and length of stay in the area. The study found that personal factors, including gender, age, education level, occupation, and length of stay, did not significantly affect public participation in solid waste management in Phaya Thai District, Bangkok, rejecting the research hypothesis. Significant differences were observed in average monthly income, with incomes below 15,000 baht being significantly different from those between 30,000 and 35,001 baht, and incomes between 15,001 and 20,000 baht being significantly different from those between 30,000 and 35,001 baht. The study also found significant differences in the level of participation in solid waste management. The research hypothesis was accepted.
