ABSTRAK
(Riska Widyah Ningrum. 26050119120002. Studi Kandungan dan Sebaran Bahan Organik di Sekitar Perairan Pekalongan. Muhammad Zainuri. dan Sri Yulina Wulandari) Perairan pantai Kota Pekalongan mengalami tekanan pembuangan limbah akibat sejumlah aktifitas industri seperti batik, perikanan, UMKM dan lain-lain yang menggunakan sungai Banger sebagai tempat pembuangan limbah. Kandungan bahan organik dari limbah akan menggangu keadaan perairan. Penelitian ini bertujuan untuk mengetahui kandungan dan pola sebaran bahan organik di perairan Muara Sungai Banger, serta pengaruh arus terhadap terjadinya persebaran tersebut. Penelitian dilaksanakan dengan pendekatan kuantitatif. Penelitian ini dilaksanakan pada 19 Juni 2022. Pengambilan data lapangan bahan organik dilaksanakan secara in situ, dan analisis dilaksanakan Laboratorium Balai Besar Teknologi Pencegahan Pencemaran Industri (BBTPPI) Semarang. Data yang diperoleh diinterpolasi dengan Citra Sentinel-2. Analisis statistik koefisien korelasi diterapkan untuk mengetahui keterkaitan data in situ dan peramalan untuk time series. Hasilpenelitian menunjukkan bahwa kandungan Total Organic Matter (TOM) di perairan Muara Sungai Banger berkisar antara 3,963 – 7,086 mg/l dan kandungan Biological Oxygen Demand (BOD) di perairan Muara Sungai Banger berkisar antara 2,632 – 4,888 mg/l. Pola persebaran bahan organik di perairan Muara Sungai Banger memiliki kandungan yang lebih tinggi di wilayah pesisir dan berkurang menuju laut lepas. Pengaruh arus terhadap sebaran bahan organik di perairan Muara Sungai Banger menunjukkan korelasi pearson 0.788 yang mengindikasikan arus mempunyai pengaruh yang besar terhadap persebaran bahan organik di perairan.
Kata kunci : bahan organik (TOM), persebaran, arus, kali banger, pekalongan.

ABSTRACT
(Riska Widyah Ningrum. 26050119120002. Study Of The Content And Distribution Of Organic Matter Around Pekalongan Regency. Muhammad Zainuri and Sri Yulina Wulandari) Coastal waters of the Dependent City are under waste disposal pressure due to a number of industrial activities such as batch, sewage, UMKM and others that use the Banger River as a waste disposal site. Kandungan bahan organik dari limbah akan menggangu keadaan perairan. The purpose of this study is to find out the content and patterns of the spread of organic matter in the waters of the Banger River, as well as the impact of the flow on the occurrence of the distribution. The research is carried out with a quantitative approach. This study was conducted on June 19, 2022. The collection of organic matter field data is carried out in situ, and analysis is carried out at the Large Industrial Pollution Prevention Technology (BBTPPI) Laboratory. Data obtained interpolated with Sentinel-2 Image. Analysis of correlation coefficient statistics is used to determine the correlation of data in situ and the recording for time series. Research has shown that the Total Organic Matter (TOM) content in the waters of the Banger River ranges from 3,963 to 7,086 mg/l and the Biological Oxygen Demand (BOD) content in the waters of the Banger River River ranges from 2,632 to 4,888 mg/l. The pattern of organic matter distribution in the waters of the Banger River Coast has higher content in the coastal areas and decreases to the offshore. The flow rate against the spread of organic matter in the Muara River Banger water shows a pearson correlation of 0.788 indicating that the flow has a major impact on the supply of organic matter in the water.
Keywords: total organics matter (TOM); distribution; current; banger river; pekalongan.
