Abstract

The mangrove ecosystem in the Brackish Forest Area, Tritih Kulon, Cilacap, is affected by various human activities, which cause an increase in total nitrate and phosphate concentrations in the waters. Nitrates and phosphates are essential nutrients that support the growth and survival of organisms. This research aims to measure total nitrate and phosphate levels, and relate them to the suitability of mudskipper habitat in the area. The research was carried out using descriptive methods, using water and sediment samples from the mudskipper habitat. Water quality is measured through parameters such as temperature, salinity, and dissolved oxygen (DO). The results showed that the total nitrate concentration in water ranged from 2.35 to 3.65 mg/L with an average of 3.12 mg/L, while in sediment it ranged from 1.02 to 1.85 mg/kg with an average of average 1.4 mg/kg. The total phosphate concentration in water is in the range of 0.6 to 0.94 mg/L with an average of 0.81 mg/L, while in sediment it ranges from 0.94 to 1.45 mg/kg with an average of 1, 22 mg/kg. Keywords: Habitat, Mudskipper, Total Phosphate, Total Nitrate

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.

Abstract

Budidaya ikan dilakukan dengan menggunakan ember-emberyang dirancang untuk memelihara ikan sekaligus sayuransecara bersamaan. Tujuan kegiatan ini adalah memberikanpengetahuan dan keterampilan memelihara ikan dan sayurandalam ember kepada ibu-ibu kelompok PKK. Metode kegiatanyang digunakan adalah belajar sambil bekerja (learning bydoing). Pelaksanaan kegiatan dengan model pembelajaranorang dewasa (andragogik) dan partisipatif dalam empattahapan yang meliputi alih teknologi melaluisosialisasi/penyuluhan aplikasi budidaya ikan dalam ember,pelatihan dan percontohan, pendampingan, dan evaluasikegiatan. Hasil kegiatan menunjukkan bahwa 94,44% ibu-ibuPKK peserta pelatihan telah mengetahui teknik budidaya ikanlele dan kangkung dalam ember serta mampu untukmengaplikasikannya dengan baik. Setelah 4 minggupemeliharaan, tinggi tanaman kangkung berkisar 18-22 cmdan sudah bisa dipanen. Setelah 6 minggu pemeliharaan,berat ikan lele mencapai kisaran 38,33-55,33 gram dengantingkat kelangsungan hidup berkisar 80-85%.
