Abstract

Solid waste generation in Indonesia reached 20 million tons in 2022, with household waste being the largest contributor at 39.98%. This study aims to compare household waste management behaviors between communities living in coastal and mountainous areas. This study uses a comparative quantitative research design with a cross-sectional approach. The total sample consisted of 225 respondents, comprising 150 respondents in the Tahaya-haya neighborhood and 75 respondents in the Ujung Bulo Wisata hamlet. The study was conducted in Tahaya-haya as a representation of mountainous areas and Karampuang Island as a representation of coastal island environments. Bivariate analysis showed a statistically significant difference in knowledge of household waste management between the communities of Tahaya-haya and Ujung Bulo Wisata (p = 0.001). Respondents in Tahaya-haya had a higher proportion of good and very good knowledge (90.6%) compared to Ujung Bulo Wisata (65.3%). Although all respondents in both areas showed a very good attitude (100%) towards waste management, this attitude was not fully reflected in actual practice. The most striking gap was seen in waste management actions, where Tahaya-haya showed better practices, while most respondents in Ujung Bulo Wisata were in the poor category. Recommendations for local governments to provide waste management infrastructure in coastal and mountainous areas.

Abstract

Aircraft noise exposure is a significant environmental health issue for communities living near airports. Although global evidence shows a link between aircraft noise and health impacts, research on regional airports in Indonesia is still very limited. This study fills that gap by investigating noise exposure levels and health impacts at Tampa Padang Airport, Mamuju, West Sulawesi. A descriptive mixed-methods approach was conducted in Bebanga Village in January 2025. Noise measurements were taken at three strategic locations (500m, 750m, and 1000m from the runway) using a Sound Level Meter calibrated according to the SNI 7231:2009 standard. Health impact data were collected from 94 respondents through validated structured interviews. Aircraft noise levels ranged from 64.5 to 92.1 dB, exceeding the residential zone quality standard of 55 dB (Indonesian regulation) and WHO guidelines (45 dB Lden). The landing phase produced higher noise levels (74.7-92.1 dB) than the take-off phase (64.5-83.1 dB). Health assessments showed that 16% of respondents experienced mild hearing impairment and 1.1% experienced moderate impairment. No sleep disturbance or psychological stress was found. Although noise exposure exceeded national and international standards, the current health impact is relatively limited, possibly due to habituation and the absence of night flights. However, long-term monitoring and implementation of noise mitigation strategies are still necessary.
