The Lubuk Lampam floodplain’s ecosystem is naturally affected by the fluctuation of the water surface. This ecosystem also receives anthropogenic substances such as nutrients and other chemicals, especially from the oil palm plantation and its industrial processing activities. The main objective of this research was to determine the trophic status of the floodplain using the trophic level index (TLI) and Carlson’s trophic state index (TSI). The water quality and the fish samples were collected and analyzed from 7 stations representing various types of floodplain habitat. The results showed that the trophic status of Lubuk Lampam was hypereutrophic (very nutrient-rich). This was also supported by the high increase of the body weight (“b” value more than 3) and the high gonadosomatic index (GSI) of the studied fishes, i.e. Osteochilus vittatus 2.53-6.81% (male) and 3.00-15.86% (female); Helostoma temminckii 0.28-3.33% (male) and 1.30-10.43% (female); and Channa striata 0.33-0.59% (male) and 0.21-2.73% (female).

The beach is a location of the largest marine debris discovery because of the dynamics of the oceanography which is in direct contact with the land. Not a few beaches are close to the river and are vulnerable to being affected by domestic or household waste that comes from river flows. Palabuhanratu Bay is one of the tourist areas affected by waste input from various community activities on the land. Thus, it is necessary to discuss the identification and analysis of marine debris pollution in Palabuhanratu Bay, especially those from the Cimandiri River. The purpose of this study was to identify the distribution of waste types based on full moon and new moon conditions in Palabuhanratu Bay, Sukabumi, West Java. Sampling of marine debris data uses the line transect method and then garbage collection is carried out when the waste has accumulated. The collected waste is then cleaned, sorted and collected by category and then recorded on the marine debris sampling sheet. The types of waste observed included seven categories. The results showed that the waste generation during the full moon was 927 items, while in the new moon was 2,099 items. The density of waste at the research site was 1.85 items/m² (full moon) and 4.20 items/m² (new moon). The types of waste that are mostly found during the full moon and new moon are plastic waste in the amount of 16.87 to 47.08% and other types of waste (wood) is 38.75 to 73.29%.

The waters of Jakarta Bay are one of the waters that are influenced by several fresh water flows that enter from the DKI Jakarta area and its surroundings. Sediment that enters the waters of Jakarta Bay is produced by the activities of the people who live in the Jakarta area and its surroundings. This study aims to analyze the sedimentation and distribution of suspended solids in the Jakarta Bay estuary using an observational approach and spatial analysis. This study uses the Inverse Distance Weighting (IDW) interpolation method. The dominant distribution of sediment in Jakarta Bay is sand with a size ranging from 0.25 to 0.125 mm. TSS (Total Suspended Solids) levels in 11 estuaries in Jakarta Bay ranged from 21 to 150 mg/L in first period and 11 ˗ 259 mg/L in second period. Sedimentation rates that occurred in 11 Jakarta Bay estuaries ranged from 11.12 g/cm2/day to 619.5 g/cm2/day in period one and 10.96 g/cm2/day to 1232.06 g/cm2/day in the second period which is located in Muara Cilincing in both periods. There is a suitable relationship between the TSS value and the sedimentation rate. Estuary TSS values and sedimentation rates are influenced by seasons and anthropogenic activities that occur in the estuary such as reclamation.

Abstrak. Penelitian ini bertujuan untuk mengetahui potensi dari filamentous algae (Spirogyra sp.) sebagai agen bioremediasi dalam mereduksi kandungan bahan organik limbah budidaya sidat. Penelitian menggunakan rancangan acak lengkap dengan perlakuan perbedaan dosis limbah (25 %, 50 %, 75 %, 100%). Wadah penelitian berupa akuarium resirkulasi menggunakan sistem carrousel. Dilakukan pengukuran secara rutin terhadap beberapa parameter kualitas air serta perubahan bobot Spirogyra sp. selama dua minggu retensi. Diperoleh hasil bahwa penurunan konsentrasi bahan organik menggunakan Spirogyra sp. berlangsung efektif hingga hari keenam. Spirogyra sp. mampu mentolelir limbah budidaya sidat pada dosis limbah 25% dan 50%. Spirogyra sp. pada perlakuan dosis limbah 50% memiliki kemampuan yang lebih baik dalam menurunkan bahan organik limbah budidaya sidat.Kata kunci : Bahan organik; Limbah budidaya sidat; Spirogyra sp.
