Nurul Fadhilah Kusumaningtyas. (2601018120014). Penentuan Status Mutu Air
Sungai Pekalongan Menggunakan Metode Indeks Pencemaran dan CCME.
(Haeruddin dan Anhar Solichin).
Sungai Pekalongan merupakan salah satu sungai di Kota Pekalongan, Jawa
Tengah. Sebagian besar masyarakat di Pekalongan bermata pencaharian sebagai
pengusaha batik, baik yang home industry atau perusahan besar. Hal tersebut dapat
menyebabkan penurunan kualitas air dan dapat menimbulkan pencemaran air
karena limbah tersebut dibuang secara langsung ke Sungai Pekalongan. Penelitian
ini bertujuan untuk mengetahui peubah yang menyebabkan pencemaran di Sungai
Pekalongan serta menentukan dan membandingkan status mutu air Sungai
Pekalongan menggunakan metode Indeks Pencemaran (IP) dan metode Canadian
Council of Minister of the Environment (CCME). Penelitian ini dilaksanakan pada
bulan Februari 2022. Metode penelitian yang digunakan yaitu metode survei.
Penentuan titik lokasi sampling menggunakan metode Purposive sampling.
Pengambilan sampel dilakukan seminggu sekali dalam 1 bulan pada pagi hari
hingga siang hari. Variabel yang diukur in situ yaitu suhu, pH, dan DO sedangkan
variabel yang diukur ex situ yaitu TSS, BOD, COD, dan Cr6+
. Hasil pengukuran
kualitas air variabel suhu 28,1 ̊C, TSS 23,33 mg/L, pH 6,23, DO 3,89 mg/L, BOD
2,2 mg/L, COD 26,58 mg/L, dan Cr6+ 0,02 mg/L. Hasil pengukuran kemudian
dibandingan dengan baku mutu kelas II sesuai dengan Peraturan Pemerintah
Republik Indonesia Nomor 22 Tahun 2021 Tentang Penyelenggaraan Perlindungan
dan Pengelolaan Lingkungan Hidup. Penentuan status mutu air menggunakan
metode IP pada stasiun I memenuhi baku mutu sedangkan stasiun II dan 3 tercemar.
Penentuan status mutu air menggunakan metode CCME memiliki nilai 71,05 yang
tergolong dalam kriteria cukup.

ABSTRACT
Nurul Fadhilah Kusumaningtyas. (2601018120014). Determination of Water
Quality Status of Pekalongan River Using Pollution Index Method and CCME.
(Haeruddin and Anhar Solichin).
Pekalongan River is one of the rivers in Pekalongan City, Central Java. Most of the
people in Pekalongan make a living as batik entrepreneurs, whether they are home
industries or large companies. However, it can cause a decrease in water quality
and create water pollution because the waste is discharged directly into the
Pekalongan River. This study aimed to determine the variables that cause pollution
in Pekalongan River. It also determines and compares water quality status of the
Pekalongan River using the Pollution Index (IP) method and CCME. This research
was conducted in February 2022. The research method used of the study was the
survey method. The sampling location was determined by using the purposive
sampling. Sampling was carried out once a week in one month in the morning until
noon. The variables measured in situ were temperature, pH, and DO, while ex situ
were TSS, BOD, COD, and Cr6+. The measurement results of water quality variable
temperature 28.1 C, TSS 23.33 mg/L, pH 6.23, DO 3.89 mg/L, BOD 2.2 mg/L, COD
26.58 mg/L, and Cr6+ 0.02 mg/L. The measurement results then compared with
class II quality standards in accordance with Government Regulation of the
Republic of Indonesia Number 22 of 2021 about Protection and Management. The
result assessed that water quality status using the IP method, at station 1 met the
quality standart while stations 2 and 3 were polluted. The CCME method had a
value of 71,05 which was classified as enough.
