Hubungan Konsentrasi Nitrat, Fosfat Dan Silikat Terhadap Kelimpahan Diatom Planktonik Di Perairan Carocok Tarusan Kabupaten Pesisir Selatan

---

Abstract
This research was carried out from December 2020 to January 2021 in
Carocok Tarusan Waters, Pesisir Selatan Regency, West Sumatra, which aims to
analyze the concentration of nitrate, phosphate and silicate, calculate the
abundance of planktonic diatoms and analyze the relationship between the
content of nitrate, phosphate and silicate to the abundance of planktonic diatoms
present. in the waters of Carocok Tarusan, Pesisir Selatan Regency. The research
method used in this study is a survey method while the determination of research
stations is carried out by purposive sampling. The results showed that the average
nitrate concentration was 0.7792 mg/l – 0.8757 mg/l, the average phosphate
concentration was 1.7220 mg/– 2.0833 mg/l and the silicate concentration was
0.6287 mg/l - 0.6835 mg/l. Planktonic diatoms found in Carocok Tarusan waters
contained 13 species from 3 classes, namely Bacillariophyceae, Chaetoceraceae
and Coscinodiscophyceae. The results of the calculation of the abundance of
planktonic diatoms are 17.82 – 20.72 Ind/L. The test conducted to determine the
relationship of nitrate, phosphate and silicate to the abundance of planktonic
diatoms was a simple linear regression test. Based on the results of the linear
regression test, it is known that the effect of nitrate concentration on the
abundance of planktonic diatoms in Carocok Tarusan waters is 00.81%, while the
remaining 99.19% is influenced by other factors, for the effect of phosphate
concentration on the abundance of planktonic diatoms in Carocok waters.
Tarusan is 8.81%, while the remaining 91.19% is influenced by other factors and
for the effect of silicate concentration on the abundance of planktonic diatoms in
Carocok Tarusan waters as much as 2.97%, while the remaining 97.03% is
influenced by other factors.
