Among the considerations for policies on air pollution are objective measurements, which are largely based on ambient air and emission data, and subjective measurements which are based on people’s perception on air quality. Many studies found that these measurements often don’t align, and subjective measurements are influenced by socio-demographic factors rather than the actual air quality. This study attempts to identify whether such incongruency between objective and subjective measurements also occur in Bandung city, and what factors determine perceived air quality. By doing statistical…

The location of Faecal Sludge Treatment Plant (FSTP) that is not planned properly can result in a low level of FSTP service, a lack of supply of faecal sludge to the FSTP, and environmental pollution problems due to illegal dumping. In this study, an analysis of important aspects in determining the location of the FSTP and the application of the Geographical Information Systems (GIS) was carried out in optimizing the coverage of FSTP services in Bandung City. The identification of criteria and weight of criteria in determining the FSTP location was performed using a pairwise comparison method…

Numerical model was used to simulate current in Bali Strait and marine debris movement around Kuta Beach in December 2011 and February 2012. Field velocity (u and v) from hydrodynamic model used as an input for simulation model of marine debris movement. From 5 points source in Jembrana, Tabanan, and Badung were released as many as 1 particles in each one of the points. The result shows with average current velocity 0.025 m/s. The marine debris in Kuta Beach, Bali came from those 5 sources. Those debris need 2-8 days in time to reach the Kuta Beach depending on the distance of the point…
