PEMETAAN SEBARAN SPASIAL KUALITAS AIR UNSUR HARA PERAIRAN TELUK LAMPUNG

Abstract

Lampung Bay plays an important
role for the terestriel area that surrounds
it. Run Of any river that contain
domestic waste into the Lampung Bay
has threatened the water quality condition.
The purpose of the research is to analyze
water quality and nutrient horizontal distribution
in Lampung Bay.This research was
held in April 2012, where spatial and temporal
survey methods was used in this research
by performing a direct physical and
chemical measurement. The results showed
a range of water quality and nutrient composition
in the Lampung Bay as follows:
temperature 28.9 - 31oC, depth 13 - 42,8
m, visibility 5 - 16.5 m, Current speed 5 -
35 m/s, pH 8.02 - 8.64, salinity 33o/oo, Suspended
Solid 27 - 86 mg/l, Dissolve oxygen
4,62 - 6.78 mg/l, Nitrate 0.002 - 0.38 mg/l
and phosphat 0.01 - 0.48 mg/l. At Overall,
nutrient composition shown a narrow
range, however condition of water quality
still in normal condition
