Abstract

ABSTRAK
(Wahyu Erfando. 26050119130131. Kandungan dan Sebaran Material Padatan Tersuspensi pada Laguna Perairan Pekalongan. Aris Ismanto dan Sri Yulina Wulandari).
Perairan Laguna Pekalongan merupakan wilayah hilir yang terintegrasi dengan muara Kali Pencongan. Sumber masukan Perairan Laguna Pekalongan dipengaruhi fenomena hidrodinamika dan aktivitas masyarakat sekitar yang mampu membawa suplai secara signifikan terhadap nilai konsentrasi Material Padatan Tersuspensi (MPT). Penelitian ini bertujuan menganalisa nilai konsentrasi dan persebaran MPT di Perairan Laguna Pekalongan. Metode penelitian berupa metode kuantitatif, dan analisa kualitatif dilakukan pada pola angin dan pola arus pasang surut. Pengambilan data MPT dilaksanakan secara in-situ pada 19 Juni 2022. Sampel dianalisa di Laboratorium Geologi, Departemen Oseanografi, FPIK, UNDIP. Persebaran MPT dan sebaran pola arus diolah dan dianalisa menggunakan Mike 21 Flow Model dan ArcGis 10.8 dan dilakukan overlay peta. Hasil penelitian di Perairan Laguna Pekalongan didapat nilai rata-rata MPT sebesar 120 mg/L. Nilai MPT pada stasiun e4 merupakan nilai tertinggi yakni sebesar 165 mg/L, dan stasiun e1 sebagai stasiun dengan nilai MPT terendah sebesar 64 mg/L. Persebaran MPT didukung oleh pola dan besaran arus pasang surut. Faktor lain yang mempengaruhi nilai kandungan MPT seperti presipitasi hujan yang membawa sumber aktivitas antropogenik / buangan dari industri sekitar, serta letak lokasi dan dasar lokasi yang berada pada dua cekungan diantara gosong pasir.
Kata kunci: Material Padatan Tersuspensi (MPT), Laguna Pekalongan, Kali Pencongan, Pasang Surut.

ABSTRACT
(Wahyu Erfando. 26050119130131. Distribution dan Content of Total Suspended Solid on Pekalongan Waters Lagoon. Aris Ismanto dan Sri Yulina Wulandari).
The waters of the Pekalongan Lagoon are a downstream area from the city dan integrated with the Pencongan River estuary. The source or supply of Pekalongan Waters Lagoon are influence by natural phenomena dan anthropogenic activities of the surrounding community which affect TSS. This study aims to determine the value of the concentration dan distribution of TSS in Pekalongan Waters Lagoon. This study aims to determine the value of the concentration dan distribution of TSS in Pekalongan Waters Lagoon. This study uses quantitative methods dan descriptive analysis conducted in 6 stations. TSS data collection was carried out in-situ on 19 June 2022. Samples were analyzed at the Oceanographic Geology Laboratory, Department of Oceanography, FPIK, UNDIP. The distribution of flow patterns of tides dan the distribution of TSS in overlay map by using processing uses the Mike module 21 Flow Model dan ArcGis 10. The results of research in Pekalongan Lagoon Waters obtained an average MPT value of 120 mg/L. The MPT value at Station E4 is the highest value, which is 165 mg/L, dan Station E1 is the station with the lowest MPT value, which is 64 mg/L. The pattern dan speed of tidal currents are one of the factors that can affect the distribution dan content of MPT. Other factors are caused by the influence of rain precipitation that brings sources of anthropogenic activity/waste from surrounding industries, as well as the depth dan type of bottom sediments in the Pekalongan Waters Lagoon which have quite a significant influence on the value of the TSS content.
