About the Seminar
Topic 1
Domestic wastewater is a major contributor to river and water body pollution, especially in areas where there are no centralized wastewater treatment plants, including some specific areas. Conventional Septic Tank as common on-site wastewater treatment facilities in Indonesia are inadequate to remove contaminants and to meet water quality standards. Improving the performance and affordability of treatment facility is a crucial element in achieving more sustainable technologies.
Currently, Conventional Septic Tanks are being modified with anaerobic-aerobic MBBR processes, integrated with microbial fuel cells, connected to solar panels as an energy source, and developed with typologies suitable for specific areas. Laboratory and pilot scale experiments have shown that the development of decentralized domestic wastewater treatment facilities has potential to provide better treatment performance, produce alternative energy, reduce operational costs, and be suited to local conditions.
Topic 2
This essay aims to craft the groundwork for re-engineering environmental engineering in/of the Anthropocene. Reflecting on experimental fieldwork in Muaragembong, Indonesia, raises the question of designing for water infrastructures for more-than-human beings and sets the stage for retracing the colonial origins and the postcolonial trajectory of environmental engineering in the postcolonial state. It concludes with a critical review of the current curriculum of environmental engineering at a technical university. (Prabaharyaka et al. Engineering Studies, 2025).
Topic 3
This study investigates the rapid reaccumulation of sediment in the Citarum-Majalaya River following a 2020 normalization project. Using HEC-RAS 2D modeling integrated with DEM, SWAT+ discharge, and field sediment data, the research quantifies post-normalization sedimentation and its impact on flood risk. Within just two years, nearly 50% of the previously dredged sediment volume had returned, reducing river capacity by 23% and significantly increasing flood-prone areas. The findings underscore the urgency of adaptive sediment management and continuous monitoring in urbanizing watersheds. Future Research Prospects:
Development of real-time sediment monitoring systems using remote sensing and IoT based sensors
Integration of machine learning with hydrodynamic models to improve sediment transport prediction accuracy
Scenario-based evaluation of nature-based solutions (e.g., riparian buffers, reforestation) for upstream erosion control
Socioeconomic impact modeling of sediment-induced flooding on vulnerable communities
Optimization of dredging schedules using predictive analytics and cost-benefit frameworks
About the Speakers
Speaker 1
Ir. Ahmad Soleh Setiyawan, ST. MT. Ph.D, is an associate professor in the Faculty of Civil and Environmental Engineering at the Bandung Institute of Technology.
