Abstract

This study investigates the solid waste management situation, focusing on general knowledge, household waste disposal behavior, and community participation in waste management among the residents of Ban Piman, Village No. 3, Piman Subdistrict, Na Kae District, Nakhon Phanom Province. A sample of 123 cases was selected from representative households, each comprising members aged 20 and over. The selection utilized a calculation formula tailored for estimating the population mean with a small sample size, employing a simple random sampling method. Data were collected by using 1) a general information questionnaire, 2) a general knowledge and solid waste disposal questionnaire, 3) a household waste disposal behavior questionnaire, and 4) a questionnaire on citizens' participation in solid waste management. It was checked for content validity by three experts. The KR-20 reliability value was 0.78 and Cronbach's alpha coefficient was 0.78 and 0.97, respectively. Data were analyzed using descriptive statistics.

The study found that the majority of the sample were female (77.24%), aged 50 years and over (=55.09, SD.=13.42), with marital status (52.85%), and completed primary school (65.04%). Additionally, 73.17% of participants were engaged in agriculture. The average monthly household income ranged between 5,000-10,000 baht (=7,321.14, SD.=7,129.70), and this group constituted the general public (85.37%). On average, households generated 0.98 kilograms of garbage per day (SD.=0.41), classified into vegetables, fruits, and food scraps (90.24%), as well as bottles, cans, and plastic bags (86.99%).
The majority of the samples did not separate waste before disposal (65.85%) and discarded it together in one bag (65.85%), with 46.34% disposing of it by incineration. Participants demonstrated general knowledge of waste disposal with an average score of 8.39 points (SD.=0.46) at the low-moderate level (72.36%). The average score for household waste disposal behavior was 35.68 points (SD.=0.97), with 69.11% at the low-moderate level. The average score for participation in community solid waste management was 67.91 points (SD.=1.07), with 85.36% at the low-moderate level. Overall, participation in community solid waste management across various aspects was at a low-moderate level.

The findings of this study offer crucial foundational information for public health officials and local administrative organizations in the region. This data can be instrumental in formulating solid waste management models that are both suitable and aligned with the local context. Such models are essential for promoting efficiency in waste management practices, ultimately contributing to sustainability goals in the community.
