Abstract

The high demand water for sanitation purposes in Engineering Faculty, Andalas University, particularly for toilet flushing systems, has not been balanced by utilization of sustainable alternative water sources. Therefore, this study aims to evaluate feasibility of rainwater quality as non-potable water source planned for implementation in the buildings of Engineering Faculty, Andalas University. The feasibility assessment refers to Regulation of Health Minister of Republic of Indonesia Number 2 of 2023. Rainwater samples collected directly from building roof downpipes, with three repetitions at the same location. The parameters of pH, dissolved oxygen (DO), and temperature were measured in situ using Lutron DO-5510 dissolved oxygen meter and portable pH meter, while turbidity, BOD, COD, TSS, and total coliform were analyzed at Environmental Engineering Department Laboratory of Andalas University using standard methods based on SNI 6989.57:2008 and US EPA Method 1699. The results indicate that pH, DO, temperature, BOD, COD, TSS, and turbidity comply with the established quality standards, whereas total coliform levels exceed the permissible limit. The presence of total coliform is presumably due to contamination from bird droppings on roof surfaces, particularly in areas surrounded by vegetation.

Abstract

This study evaluates the efficiency of water usage in the Department of Environmental Engineering at Universitas Andalas (Unand) by analyzing water consumption volume, identifying potential leaks, and comparing the findings with applicable standards for laboratories and offices. A 1.5-inch water meter was installed at the outlet of the rooftop reservoir on the 4th floor to measure water usage volume, and manual attendance devices were used to record the number of water users in the office and laboratory. Leakage testing was performed using the step test method, where water flow was stopped for 16 hours overnight to monitor changes in the water meter readings, with results indicating no leakage. The study found that the highest water consumption was 39.66 L/person/day in the laboratory and 55.06 L/person/day in the office. Water consumption in laboratories was found to be 100-200 L/person/day according to the standard, while water use in offices slightly exceeds the Indonesian National Standard (SNI) 03-7065-2005 of 50 L/person/day. The study recommends implementing water conservation technologies, such as automatic faucets and dual-flush toilet systems, to reduce water consumption and enhance water efficiency.

Abstract

This study examines the resilience variables of urban Drinking Water Supply Systems (WSS) in responding to floods, with a focus on West Sumatra Province, Indonesia, using the Fuzzy Delphi Method (FDM). The study identifies three main resilience properties: robustness, recovery, and learning, within a temporal framework. Thirteen sub-properties and 41 indicators were validated using FDM by 10 experts in fields relevant to the research topic. As a result, 12 sub-properties were accepted by expert consensus, while one sub-property, namely governmental situation awareness, was rejected because all three of its indicators failed to meet the validation criteria. A total of 33 out of 41 indicators were considered significant, relevant, and useful by the expert panel. Furthermore, the findings emphasize the critical role of the governmental dimension in determining the resilience level of SPAM in West Sumatra Province. These results will serve as a guide for policymakers in prioritizing resilience-based decisions to mitigate flood threats.
