RINGKASAN
Chrysophyta merupakan divisi fitoplankton yang sensitif terhadap perubahan
lingkungan perairan. Tujuan penelitian adalah mengetahui kelimpahan dan distribusi
horizontal Chrysophyta serta faktor fisika dan kimia perairan, mengetahui tingkat
kesamaan antarstasiun, serta mengetahui korelasi antara kelimpahan dan distribusi
horizontal Chrysophyta dengan faktor fisika dan kimia perairan Waduk Penjalin.
Kelimpahan Chrysophyta dihitung dengan metode modifikasi Lackey Drop
Microtransect Counting Chamber. Pola distribusi horizontal Chrysophyta dianalisis
dengan Indeks Morisita. Tingkat kesamaan antarstasiun berdasarkan kelimpahan,
distribusi horizontal Chrysophyta, serta faktor fisika dan kimia dianalisis Cluster dan
Simper. Korelasi kelimpahan dan distribusi horizontal Chrysophyta dengan faktor
fisika dan kimia perairan dianalisis menggunakan korelasi regresi linier berganda.
Kelimpahan Chrysophyta yang didapatkan berkisar 7.082-159.777 ind.l-1 dengan
spesies yang paling melimpah adalah Cyclotella meneghiniana. Pola distribusi
horizontal Chrysophyta didapatkan seragam. Hasil analisis Cluster kelimpahan
Chrysophyta didapatkan kesamaan yang rendah dan hasil analisis Simper didapatkan
spesies yang berkontribusi memberikan ketidaksamaan adalah Cyclotella
meneghiniana. Hasil analisis Cluster distribusi horizontal Chrysophyta didapatkan
kesamaan yang rendah dan hasil analisis Simper didapatkan spesies yang
berkontribusi memberikan ketidaksamaan adalah Achnanthes brevipes, Amphiprora
ovalis, dan Chaetoceros peruvianum. Hasil analisis Cluster faktor fisika dan kimia
didapatkan kesamaan yang tinggi dan hasil analisis Simper didapatkan faktor fisika
dan kimia yang berkontribusi memberikan ketidaksamaan adalah silika dan TSS.
Korelasi kelimpahan Chrysophyta dengan faktor fisika dan kimia adalah kuat dengan
koefisien korelasi 0,685 dan koefisien determinasi 47%, serta persamaan Y =
1.856,850 - 55.478,220 (Penetrasi Cahaya) + 907,835 (Kedalaman) + 2.909,913
(Suhu) + 94,891 (TSS) - 2.892,899 (DO) - 265,315 (BOD5) - 7.601,391 (NO3) +
7.782.500,191 (PO4) + 55,107 (Si). Korelasi distribusi horizontal Chrysophyta
dengan faktor fisika dan kimia adalah sedang dengan koefisien korelasi 0,539 dan
koefisien determinasi 29%, serta persamaan Y = 1,610 + 0,467 (Penetrasi Cahaya) 0,062 (Kedalaman) - 0,086 (Suhu) - 0,028 (TSS) + 0,073 (DO) + 0,069 (BOD5) +

SUMMARY
Chrysophyceae is one of the divisions of phytoplankton that sensitive to
changes in the aquatic environment. The research objective was to determine the
abundance and horizontal distribution of Chrysophyceae also physical and chemical
factors, determine the degree of similarity between the stations, and determine the
correlation between the abundance and distribution of Chrysophyceae horizontally
with factor of physics and chemistry Penjalin Reservoir. Chrysophyceae abundance
calculated using Lackey Drop Microtransect Counting Chamber Method.
Chrysophyceae distribution patterns were analyzed by Morisita Index. The degree of
similarity between the stations based abundance, horizontal distribution of
Chrysophyceae, physical and chemical factors analyzed Cluster and continued with
Simper. The correlation between the abundance and horizontal distribution of
Chrysophyceae with physical and chemical factors were analyzed using multiple
linear regression correlation. Chrysophyceae abundance obtained ranged 7,082159,777 ind.l-1. The most abundant species Chrysophyceae is Cyclotella
meneghiniana. Chrysophyceae horizontal distribution patterns are uniform. Cluster
and Simper analysis of Chrysophyceae abundance obtained 30.56% similarity with
the species that contributes inequality is Cyclotella meneghiniana. Cluster and
Simper analysis of Chrysophyceae horizontal distribution obtained 9.47% similarity
with the species that contributes inequality are Achnanthes brevipes, Amphiprora
ovalis, and Chaetoceros peruvianum. Cluster and Simper analysis results of physical
and chemical factors obtained 86.09% similarity with factors that contribute
inequality are silica and TSS. Correlation of Chrysophyceae abundance with physical
and chemical factors are strong with correlation coefficient of 0.685 and
determination coefficient of 47%, and regression equation Y = 1,856.850 –
55,478.220 (Penetration of Light) + 907.835 (Depht) + 2,909.913 (Temperature) +
94,891 (TSS) + 0,000 (pH) – 2,892.899 (DO) – 265.315 (BOD5) – 7601.391 (NO3)
+ 7,782,500.191 (PO4) + 55.107 (Si). Correlation between horizontal distribution of
Chrysophyceae with physical and chemical factors are medium with correlation
coefficient of 0.539 and determination coefficient of 29%, and regression equation Y
= 1.610 + 0.467 (Penetration of Light) – 0.062 (Depht) – 0.086 (Temperature) –
