Abstract

This research is about the effect of filter media grain size on the headloss and backwash duration of rapid sand filter unit. The purpose of this study is to analyze the effect of filter media grain size on headloss and backwash duration. In this research, filter media with 3 different sizes are used, which are assessed based on the effective size (ES) and uniformity coefficient (UC) parameters. Data collection consists of sieve analysis of media filter, headloss test, turbidity test, and TSS test. The Headloss test is carried out on a laboratory scale using a prototype filter unit. Sieve analysis of media filter, turbidity test, and TSS test of backwash water are carried out at IPA 2 PT PAM Lyonnaise Jaya. The results show that each value of headloss for large filter media (ES = 1.29 mm; UC = 1.40), small filter media (ES = 0.87 mm; UC = 1.51), and mixed filter media (ES = 0.89 mm; UC = 1.49) are 4 cm, 5.5 cm, and 4.6 cm. The optimum backwash duration on large filter media, small filter media, and mixed filter media are 15 minutes, 13 minutes, and 14 minutes.

Abstract

Urban public health initiatives rely heavily on community participation to ensure success and sustainability. This study explores the socio-demographic determinants of community engagement in the public health initiatives of Koja Subdistrict, Jakarta. A cross-sectional survey was conducted, employing both qualitative interviews and quantitative questionnaires to gather data from a representative sample. Binary logistic regression was used to analyze the data, focusing on aesthetics, public health sanitation performance, community socialization, gender, age, and education. The findings reveal that aesthetic considerations, perceived sanitation performance, socialization practices, and demographic factors significantly influence the willingness to participate. Aesthetics and community socialization positively impacted engagement, while perceived high sanitation performance paradoxically discouraged individual participation. Furthermore, demographic factors such as gender, age, and education level showed varying degrees of influence, with gender disparities and higher education correlating with increased engagement. This study contributes to understanding public health participation dynamics and offers insight into designing tailored community engagement strategies. Policymakers and health officials can leverage these insights to effectively enhance community involvement and address public health challenges.

Abstract

Urban sanitation remains a critical public health issue, with community participation recognized as a key factor in the success of sanitation programs. This study aims to explore the multi-dimensional factors influencing community participation in the urban setting of Koja. Through a mixed-methods approach, including surveys, interviews, and observational studies, we investigated how socio-demographic factors such as age, gender, income, and occupation, as well as aspects of sanitation governance, infrastructure, and educational interventions, interplay to affect community engagement. The study revealed that while infrastructure and access are crucial, socio-economic and gender-related barriers significantly impact participation levels. Educational level emerged as a strong predictor of engagement, indicating that awareness and knowledge play a critical role in motivating community involvement. Furthermore, sanitation governance and the quality of policies and monitoring were found to be instrumental in shaping public attitudes towards participation. The research highlights the necessity for integrated and inclusive sanitation policies that address the local context and socio-economic diversity of urban populations. The findings underscore the importance of targeted educational campaigns and the fostering of collaborative community relationships to enhance participation in sanitation programs. This study contributes to the discourse on urban sanitation by providing a nuanced understanding of the complex factors at play in community-based sanitation efforts, offering insights for policymakers to improve public health outcomes.
