Abstract

Hidayati NV.  2022. Identification of pollution in wetlands: baseline data in addressing environmental threats for food safety and security. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang  27 Oktober 2022. pp. 27-39. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Wetlands include swamps, marshes, billabongs, lakes, salt marshes, mud flats, mangroves, coral reefs, and peat swamps. Located in the transition between aquatic and terrestrial environments and having features of both, wetlands are considered to be one of the most productive ecosystems in the world. Wetlands provide important ecosystem services that provide economic, social, environmental, and cultural benefits. On the other hand, wetlands act as traps for pollutants, including heavy metals, plastics, and pesticides. These pollutants come from point and non-point sources, both terrestrial and marine. Development activities, draining water, urbanization, industry, and poor agricultural practices have been the cause of pollution and even damage to wetlands and their ecosystem functions. Several studies show the accumulation of these pollutants in aquatic organisms, including consumption fish that enter through food webs. It is crucial to understand the accumulation of contaminants through food webs because once these pollutants reach consumers above them, including humans, they can produce chronic effects and even death. Thus, more serious attention needs to be given to wetland management within the framework of food safety and security.

Abstract

Graphical Abstract   Highlight Research First study to analyze the three-year spatiotemporal distribution of nitrate and phosphate in the Serayu River Basin. Reveals seasonal and spatial nutrient hotspots linked to agricultural runoff and domestic activities. Identifies strong correlations: nitrate with TSS and COD (2021), and phosphate with COD (2021–2022) and pH (2023). Supports integrated watershed management through evidence-based nutrient pollution assessment using PCA and spatial mapping.     Abstract The Serayu Watershed is a vital area in Indonesia, where agricultural runoff contributes to nutrient enrichment in rivers. This study offers novelty as it is the first to analyze the spatiotemporal distribution of nitrate and phosphate in the Serayu River over a three-year period (2021–2023). The research aims to support sustainable watershed management by examining nutrient dynamics and their correlation with environmental parameters such as dissolved oxygen (DO), pH, total suspended solids (TSS), and chemical oxygen demand (COD). Water sampling was conducted at 15 stations across upstream, midstream, and downstream segments. Data were analyzed using Microsoft Excel and PAST 4.03, applying Principal Component Analysis (PCA) and biplot methods. Results showed nitrate levels were highest downstream in 2021, but shifted upstream in 2022–2023, likely due to organic matter decomposition. Phosphate remained highest midstream throughout the period, linked to domestic activity and land use. Nitrate levels fluctuated seasonally, especially during the rainy season, while phosphate levels were relatively stable. Spatial mapping highlighted dynamic nitrate changes in Banjarnegara and Cilacap, with phosphate distribution remaining more uniform. Correlation analysis revealed nitrate was related to TSS and COD in 2021, had no significant correlation in 2022, and was linked with pH in 2023. Phosphate consistently correlated with COD and pH. These findings emphasize that both natural and human-induced factors drive nutrient variability in the Serayu watershed, underlining the urgency of integrated watershed management to control nutrient pollution and protect water quality.
