【 摘 要 】

Bandung area is known as the center of economic growth in West Java. Bandung is also surrounding by mountains, therefore the morphological form of its territory is like a giant bowl. The previous study showed that the concentration of Sulfur in air particulate matter from Bandung is high. The objective of this study is to examine the use of conditional probability function (CPF) to identify directions of Sulfur sources using data collected from Bandung. CPF method is an advanced tool that analyzes pollutant source contributions in relation to the winds at the site and has been applied to find source directions. Data collection were done by air particulate sampling using GENT Sampler for 24-hours, once a week in Bandung during 2012-2014. EDXRF technique was applied for Sulfur analysis. The CPF values for Sulfur presented in polar plots, for fine and coarse particles. From this polar plot, the contributions of Sulfur in fine particles were coming from all sectors in Bandung whereas, in coarse particles, Sulfur dominated from the northern sector of Bandung.
