The Citarum River supports key sectors such as agriculture, energy, and raw water supply. However, pollution poses significant threats to public health and the regional economy. In response, the Government of Indonesia issued Presidential Regulation No. 15 of 2018 to accelerate the control of pollution and degradation in the Citarum watershed. The “Citarum Harum” program, launched as part of this regulation, aims to improve river water quality through more coordinated and synergistic pollution control efforts. This study aims to determine the water quality status and pollution levels of the river using the Pollution Index (PI) method following the enactment of Presidential Regulation No. 15 of 2018. Water quality data were collected at three monitoring points along the Cibeureum Hilir, Cisangkan Hilir, and Cimahi Leuwigajah segments. The parameters analyzed included physical (TSS) and chemical (DO, BOD, COD,, total phosphate) indicators, which exceeded water quality standards at all three locations. The PI values indicated slightly to moderately polluted water conditions during the implementation of the Citarum Harum program. This condition is attributed to the strict supervision by military authorities over industrial and domestic waste disposal activities during the implementation of Citarum Harum program.
