ABSTRAK
Mirza Fredyaniza Lazuardi. 260 501 171 200 16. Analisis Karbon Organik Total
Pada Sedimen Dasar di Muara Sungai Banger Pekalongan Jawa Tengah (Lilik
Maslukah dan Sugeng Widada).
Sungai Banger terletak di kecamatan Pekalongan Utara yang merupakan sungai
dengan banyak aktivitas manusia seperti pemukiman, industri, pertambakan,
pertanian, dan aktivitas perikanan di sepanjang aliran sungainya. Banyak limbah
dari aktivitas tersebut berakhir di sungai. Bahan organik yang terkandung di dalam
limbah apabila melebihi ambang batas dapat menyebabkan perairan yang eutrofik.
Konsentrasi karbon organik pada sedimen dapat dijadikan indikator untuk
mengetahui kualitas perairan. Penelitian ini bertujuan untuk mengetahui sebaran
karbon organik total (KOT) dan hubungannya dengan jenis dan statistik sedimen.
Analisis yang dilakukan meliputi analisis KOT dengan metode LOI (Loss of
Ignition), Analisis ukuran butir sedimen, statistik sedimen, pasang surut dan arus
permukaan. Hasil penelitian menunjukan Muara Sungai Banger didominasi oleh
fraksi sedimen lanau dengan konsentrasi KOT berada dalam kategori sedang-tinggi
di angka 5,1% 21,63%. Korelasi antara KOT dengan jenis dan statistik sedimen
dapat dianalisis dengan SPSS menggunakan metode bivariat pearson. KOT
memiliki nilai pearson correlation yang positif terhadap fraksi lanau (0.884). KOT
banyak ditemui pada sedimen yang memiliki ukuran butir halus yang lebih mudah
untuk mengadsorpsi karbon yang ada di perairan. Nilai pearson correlation antara
KOT dengan nilai mean menunjukan hubungan yang negatif (-0.813). Nilai mean
yang tinggi menunjukan bahwa ukuran butir sedimen yang lebih kasar, artinya
apabila nilai mean sedimen semakin besar maka KOT yang ditemukan semakin
rendah konsentrasinya.

ABSTRACT
Mirza Fredyaniza Lazuardi. 260 501 171 200 16. Analysis of Total Organic
Carbon in Basic Sediment at Banger River Estuary, Pekalongan, Central Java
(Lilik Maslukah and Sugeng Widada)
The Banger River is located in the North Pekalongan sub-district, a river with many
human activities such as human settlement, industry, aquaculture, agriculture, and
fishing activities along its river. Much of the waste from these activities end up in
rivers. If it exceeds the threshold, the organic matter contained in the waste can
cause eutrophic waters. Carbon concentration in sediment can be used as an
indicator to determine water quality. This study aims to determine the distribution
of total organic carbon (TOC) and its correlation with sediment type and sediment
statistics. This research was carried out on August 24, 2021. The analysis includes
TOC analysis using the LOI (Loss of Ignition) method, sediment grain size analysis,
sediment statistics, tides, and surface currents. The results showed that the Banger
River Estuary was dominated by the silt sediment fraction with organic carbon
concentrations in the medium-high category at 5.1% to 21.63%. The correlation
between TOC and sediment type and sediment statistics can be analyzed by SPSS
using the Pearson bivariate method. TOC has a positive Pearson value correlation
with the silt sediment fraction (0.884). TOC is mostly found in sediments that have
a fine grain size that is easier to adsorb carbon in the waters. The Pearson
correlation value between TOC and the mean value shows a negative relationship
(-0.813). A high mean value indicates that the grain size of the sediment is coarser,
meaning that if the mean sediment value increases, the TOC found will be lower in
concentration.
