DISTRIBUSI SPASIAL TINGKAT PENCEMARAN AIR DI DAS CITARUM

Andriati Cahyaningsih, Budi Harsoyo

Abstract


Penelitian ini bertujuan untuk menggambarkan distribusi spasial pencemar air di DAS
Citarum. Studi ini menggabungkan teknologi penginderaan jauh, Sistem Informasi
Geografis (GIS) dan data kualitas air. Informasi tentang DAS Citarum dikumpulkan
dari interpretasi Landsat TM. Kualitas air dikumpulkan dari data sekunder dari 33 titik
sampel nilai BOD. Semua informasi diproses oleh GIS. Data dianalisis dan diplot ke
dalam peta yang menggambarkan distribusi polutan air di DAS Citarum.

This study was aimed to describe spatial distribution of water pollutant at Citarum
watershed. This study combined remote sensing technology, Geographic Information
System (GIS) and water quality data. Information on Citarum watershed was collected
from Landsat TM interpretation. Water quality was collected from secondary data of 33
sample point BOD values. All information was procesed by GIS. The data were analysis
and plotted into a map described water pollutant distribution at Citarum watershed.
