ABSTRACT Flash floods in Aceh frequently damage drinking water infrastructure, resulting in the loss of access to safe water for affected communities. Rapid restoration of clean water services, combined with strengthening community operational capacity, is essential to prevent further public health risks. This article aims to present an integrated model that combines the deployment of emergency water treatment technology with community-based technical training in a post-flash flood context in Aceh, Indonesia. The program was implemented through a participatory and phased approach, including rapid needs assessment, commissioning of a skid-mounted mobile water treatment unit, operator training, and routine monitoring. Water quality assessment results indicate a consistent reduction in physico-chemical parameters from raw water to treated water and final drinking water, demonstrating stable performance of the system under fluctuating field conditions. In addition, community satisfaction evaluation shows that most respondents expressed high satisfaction with service delivery, system performance, and program impact on health and basic water needs, particularly in terms of accessibility, system reliability, and operational ease at the local user level. The deployed unit successfully restored access to safer water for affected communities while maintaining operational stability under variable field conditions. Furthermore, the training program improved local operator competence and strengthened safe water handling practices at the household level. This integrated approach, combining non-chemical water treatment technology and community empowerment, provides a practical and replicable model for post-flood emergency drinking water supply, emphasizing recontamination risk control and community-based operational sustainability. Keywords: Flash Flood, Emergency Water Purification, Community Training, Safe Drinking Water, Disaster Response.

Flood inundation mapping is a critical tool for urban flood risk assessment in tropical cities. This study investigates flood inundation extent in Medan Maimun Sub-district, Medan City, one of the most flood-prone areas in North Sumatra, Indonesia, where flood depths of approximately 3 meters were reported in February 2022 and December 2023. The study aims to: (1) determine design rainfall through frequency analysis and calculate design flood discharge for return periods of 2, 5, 10, 25, 50, and 100 years using the Nakayasu Synthetic Unit Hydrograph (SUH Nakayasu) method; (2) simulate flood routing using two-dimensional hydraulic modeling; and (3) map the resulting flood inundation extent for each return period. Rainfall frequency analysis used annual maximum rainfall data from two stations for the period 2014–2023, with the Log Pearson III method selected based on Chi-Square goodness-of-fit testing. Design flood discharges ranged from 383.403 m³/s at the 2-year return period to 555.149 m³/s at the 100-year return period. Flood routing and inundation mapping were performed using HEC-RAS version 5.0.7 integrated with RAS Mapper. Total inundation area increased from 110.982 ha at the 2-year return period to 126.581 ha at the 100-year return period, covering approximately 41.6% of the sub-district area at the 100-year return period. The model was not formally calibrated or validated against observed flood data; results should be interpreted as indicative of relative flood risk patterns rather than precise predictions. The flood inundation maps produced provide a useful scientific basis for flood mitigation planning in Medan city, Indonesia.

Rapid population growth has both a positive and a negative impact, such as an increase in household waste generation. This also becomes a new chain of problems in other aspects, such as health, flood, air pollution, and environmental pollution. To overcome this problem, an integrated waste management system is needed. Household waste, especially inorganic waste, was valuable. The application was developed to promote a new paradigm; waste is a new source of money. As well as help run a circular economy in the waste recycling industry. The application to be built is "WasteApp", an independent household waste management application that can track and help manage it. This application is built using the Android operating system to make it a user-friendly tool. An application trial was conducted in Geulanggang Baro village, Bireuen district involving the operator, local government, and community. This location was chosen because they already have informal waste management, and it is easier to maximize by information technology intervention. The final result of this research is the â€œWasteAppâ€ application based on android to manage household waste independently. The community, operator, and local government can work waste independently and systematically through this system. This application contains several menus, including the Home menu, login, register, and the main menu, namely the waste sell history and selling waste, as well as educational articles that contain how to manage waste, from sorting waste to the recycling process. Community participation was needed to increase to full implementation of good waste management.
