Assessment of Total Suspended Solid Concentration Dynamics Based on Geospatial Models as an Impact of Anthropogenic in Pekalongan Waters, Indonesia

Abstract

Changes in total suspended solids (TSS) concentrations provide information to determine the quality of the carrying capacity of waters as marine resources. This research aims to analyze the concentration and distribution of TSS in marine waters due to anthropogenic impacts on land. The concentration and distribution changes of TSS were analyzed using a geospatial model approach. The in-situ data were collected in August 2021 and June 2022 at 11 stations in the east monsoon and analyzed in the laboratory using the gravimetric method. The results show that TSS concentration changes at the study area significantly increased concentration from 40,3-85,4 mg/L in 2021 to 64,7-140,5 mg/L in 2022, increased by 37,6 – 39,2%, distributed to the east in open water due to the influence of the surface current, which is driven by the wind and tidal current. The anthropogenic factors, such as land use and micro-industrial activities, were dominantly correlated with the increase in TSS concentration in the waters, which is driven by input from land due to the influence of precipitation. This research provides comprehensive monitoring, evaluating, and managing scheme data and information to researchers, local governments, and environmentalists for mitigation planning to reduce the subtraction of water quality due to anthropogenic impacts.

Determination of chlorophyll-a and its distribution in the waters of the mangrove forest rehabilitation area in Mojo Estuaria, Pemalang

“…The wind data used is at one-hour intervals for an entire month, in April 2024, representing the east season each year. Wind data is used to determine the dominant characteristics of the wind's direction and speed that passes over Mojo River Estuary, Pemalang's waters (Ridarto et al, 2023).…”

Total Suspended Solid Concentration Dynamics and Distribution Based on Geospatial Models in Mojo River Estuary, Pemalang

“…The results of this limitation are later exported as vector data in the form of coastline data in .shp format and corrected using the on-screen digitize method on images that have been given a composite RGB color display on the three images data. The coastline extraction uses the Normalized Difference Water Index algorithm to distinguish between water and land boundaries using Near-Infrared (NIR) (band 8) and green band (band 3) (McFeeters, 1996;Du et al, 2016;Kamaruddin et al, 2022;Ridarto et al, 2023).…”

“…The presence of suspended solids material (MPT) in waters can be sand, mud, clay, colloids, as well as organic matter such as plankton and other organisms. Hydrooceanographic factors such as wind, rainfall, waves, currents, and tides affect MPT in coastal and estuarine areas (Ridarto et al, 2023).…”

Studi Persebaran Kandungan Fosfat dan Material Padatan Tersuspensi di Perairan Muara Sungai Slamaran, Kota Pekalongan

“…Menurut Pradipta et al, (2013), sungai Slamaran memiliki bagian muara sungai yang menghubungkan antara daerah aliran sungai (DAS) dengan perairan pantai. Ridarto et al, (2023) menyatakan, bahwa terdapat aktivitas berupa kegiatan rumah tangga, industri, pertanian dan pertambakan yang menghasilkan limbah di sepanjang daerah aliran sungai Slamaran. Limbah yang masuk ke DAS Slamaran tersebut akan terurai menghasilkan nutrien dan terbawa menuju muara sungai.…”
