Abstract

Pengujan Village is a coastal area located in Bintan Regency, where the livelihoods and food sources of the community are largely derived from the sea. The increasing activities in fishing and seafood processing have led to the negative impact of rising household waste. The purpose of this community service is to educate the Pengujan Village youth organization (karang taruna) on waste segregation and the processing of household plastic waste into paving blocks. The methods used in this activity include preparation, implementation, and evaluation. Data were analyzed using the paired sample T-test. The results show a significant difference in knowledge before and after the education, with a p-value of 0.014 (α < 0.05). This education is a concrete step to enhance the community's knowledge in waste segregation and the processing of household plastic waste into paving blocks that have economic value.

Abstract

Objective: This study aimed to determine the relationship between socio-demographic characteristics such as age, gender, education level, employment status, time spent at home, length of residence, and proximity to landfill with public perception of air pollution among communities living near landfill sites in urban Indonesia. Study Design: Quantitative, descriptive cross-sectional study. Place and Duration of Study: Conducted in a landfill-adjacent urban area in Tanjungpinang, Kepulauan Riau, Indonesia, from May 6 to May 8, 2024. Methodology: A total of 50 respondents aged 18 years and above were selected using purposive sampling. Data were collected through structured questionnaires assessing demographic characteristics and perceptions of air quality. Statistical analysis was conducted using descriptive statistics and chi-square tests with a significance level of p < 0.05. Results: The study found statistically significant associations between education level and perception of air pollution (p = 0.020), as well as between employment status and perception (p = 0.020). Other factors—age, gender, time spent at home, length of residence, and distance from the landfill—were not significantly associated with air pollution perception. Conclusion: Education and employment status play a key role in shaping how communities perceive air pollution near landfill sites. These findings suggest that environmental health interventions should prioritize public education and awareness programs, especially targeting individuals with lower education levels and those not engaged in formal employment.

Abstract

Background: Landfills are recognized sources of emissions of various gaseous pollutants, including ammonia (NH3), which can cause odor nuisances. The Ganet Landfill in Tanjungpinang City is currently managed using an open dumping system due to operational limitations. Objective: This study aimed to analyze the dispersion profile of ammonia gas originating from the Ganet Landfill and to examine the differences in its dispersion patterns between the rainy and dry seasons.Methods: Ammonia concentration data were collected based on one-hour average measurements at ten monitoring locations: one at the landfill unloading area and nine at surrounding points, including residential zones and adjacent roadways. These data were utilized as input for dispersion modeling using AERMOD software. Meteorological data for the year 2023 were estimated using historical data from 2019 to 2023 to support the modeling process.Results: The monitoring results indicated that ammonia concentrations at all measured locations complied with the quality standard of <2 ppm. AERMOD modeling for one-hour average concentrations showed that the highest predicted concentration within the landfill area was 0.08 μg/Nm3. In both the rainy and dry seasons, the dispersion of ammonia was predominantly toward the southwest, aligning with the prevailing wind direction in the area. The seasonal comparison revealed a difference in ammonia concentrations at a 7 km radius from the landfill center: 0.001 μg/Nm3 during the rainy season and 0.002 μg/Nm3 during the dry season.Conclusion: The modeling results corroborated the monitoring findings, indicating that the highest concentrations of ammonia occur at locations closest to the landfill, particularly in the southwest direction, consistent with the dominant wind patterns. Keywords: Ammonia; air pollution; dispersion modeling; landfill; seasonal variation
