This study addresses the issue of intermittent water supply in Jakarta, focusing on the use of underground water storage tanks (UWSTs) to stabilize water availability in three commercial buildings. Surveys showed that the average pressure from drinking water utilities over five consecutive days was only 4 m head—considered critically low. The research proposes installing UWSTs to store water during off-peak hours for redistribution during peak demand or supply outages. The study also analyzed the influence of commuter and resident water-use patterns, with an estimated tank capacity of 25.69…

Defining urban agglomeration boundaries using conventional administrative approaches often creates a ‘statistical illusion’ that distorts the functional spatial reality, while alternative dynamic models (such as cellular automata and agent-based models) are hindered by an absolute dependency on the availability of historical spatio-temporal data. Addressing this epistemological deadlock, this article proposes a new methodological framework that deconstructs the dynamics of metropolitan agglomeration evolution through the integration of space syntax, fractal dimension, and spatial clustering…
