Abstract

Horizontal flow constructed wetland (HFCW) is a method mimicking natural processes in which plantations are used to treat wastewater. This method demonstrates superior efficacy in the removal of organic pollutants and total nitrogen. Furthermore, it offers the advantage of reduced operational and maintenance expenses. This research employs a household-scale HFCW unit, utilizing water hyacinths (Eichornia crassipes) to treat greywater from a single house. The study aims to assess the HFCW unit's performance in treating greywater at a household scale, with effluent quality compared against Minister of Environment and Forestry Regulation (Regulation Number 68/2016 on Domestic Wastewater Quality Standard) using testing methods in accordance with the Indonesian National Standards (SNI). The results indicate that the HFCW unit removal efficiencies after two days retention time are: BOD5 (74%-93%), COD (47%-80%), TSS (55%-97%), oil and grease (50%-94%), and ammonia (46%-99%). After three days, the unit generally demonstrates improved performance, which are: BOD5 (67%-96%), COD (57%-91%), TSS (51%-97%), oil and grease (11%-99%), and ammonia (35%-99%). Overall, the effluent quality meets government standards for both two- and three-days retention time, establishing the HFCW unit as an effective household-scale greywater treatment solution.

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.
