ABSTRAK
(Syifa Arrahmah, 26050119140050. Analisis Parameter Kualitas Air Di
Perairan Muara Sungai Banger Kabupaten Pekalongan. Lilik Maslukah dan
Denny Nugroho Sugianto).
Perairan Sungai Banger memiliki kondisi masukan bahan organik yang
beragam dari kegiatan antropogenik, industri batik dan kegiatan perikanan. Bahan
organik yang terkandung ini mampu memberikan gambaran kondisi perairan di
daerah tersebut. Bahan organik mampu digambarkan melalui parameter BOD5,
COD dan parameter kualitas perairan lainnya. Penelitian ini bertujuan untuk
mengetahui kandungan bahan organik terkandung melalui bahan organik total
terukur dan menganalisis kondisi perairan dari parameter BOD5 dan COD.
Penelitian ini dilakukan dengan menggunakan sampel air yang diukur nilai bahan
orgnik total (BOT), BOD5 dan COD serta data parameter kualitas air yang diukur
secara in situ berupa salinitas, suhu, pH, kecerahan dan DO. Hasil pengamatan
menunjukan nilai BOT terukur berkisar 5,40 – 9, 60 mg/l, nilai BOD5 terukur
berkisar 2,82 – 5,076 mg/l dan nilai COD terukur berkisar 28,85 – 41,87 mg/l.
Keterkaitan parameter terukur dan hasil uji di kaitkan menggunakan Analisis
Komponen Utama atau Principal Component Analysis (PCA). Uji PCA
memberikan gambaran komponen F1 dan F2 yang bisa mengintrepretasikan
persentasi sebesar 66,72% dari ragam parameter yang digunakan.

ABSTRACT
(Syifa Arrahmah, 26050119140050. Analysis of Water Quality Parameters
in the Waters of the Banger River Estuary, Pekalongan Regency.Lilik Maslukah
and Denny Nugroho Sugianto).
Banger River waters have various organic matter input conditions from
anthropogenic activities, the batik industry and fishing activities. The organic
matter contained is able to provide an overview of the condition of the waters in the
area. Organic matter can be described through the parameters BOD5, COD and
other water quality parameters. This study aims to determine the content of organic
matter contained through measured total organic matter and analyze water
conditions from the parameters BOD5 and COD. This research was conducted
using water samples whose values were measured for total organic matter (BOT),
BOD5 and COD as well as water quality parameter data measured in situ in the
form of salinity, temperature, pH, brightness and DO. The results showed that the
measured BOT values ranged from 5.40 – 9.60 mg/l, the measured BOD5 values
ranged from 2.82 – 5.076 mg/l and the measured COD values ranged from 28.85 –
41.87 mg/l. The relationship between measured parameters and test results is linked
using Principal Component Analysis (PCA). The PCA test provides an overview of
the F1 and F2 components which can interpret a percentage of 66.72% of the
various parameters used.
Keywords: organic matter, BOD5, COD, Banger River
