| Summary: | The water quality index (WQI) is a tool for determining air quality status which is
needed in monitoring and managing air resources. WQI is expected to be able to
provide a true representation of river quality to the public and decision makers.
The Upper Citarum watershed, which is one of the largest streams in West Java
Province, is one of the water bodies that is closely related to the activities of the
surrounding community. Therefore, an appropriate air quality index is needed to
describe the air quality in the Hulu Citarum watershed. The main objective of this
research is to validate the method for developing an air quality index so that it is
suitable for the Upper Citarum watershed. The data used includes primary data
obtained from interviews and questionnaires with panelists in the air sector which
was carried out in two stages as well as secondary data originating from the West
Java DLH as well as previous research regarding the comparison of the air quality
index for the Upper Citarum watershed. Analysis carried out on the results of
interviews and questionnaires found that there were 9 parameters and their weights
that represented 4 categories of decline for the Upper Citarum watershed, namely
TSS (0.07), color (0.038), and pH (0.059) which represented physical characteristic
categories; BOD (0.139), COD (0.094), and DO (0.088) which represent a
decrease in oxygen and organic levels; Nitrate (0.096) and Total Phosphate (0.105)
which represent eutrophication; as well as fecal coli (0.313) which represent health
hazards. This gives the impression that the selection parameters through the
development method are in accordance with several air quality indices that apply in Indonesia. |
