Abstract

Perairan karst merupakan perairan dengan suatu keunikan yang dapat mempengaruhi organisme di dalamnya, salah satunya adalah makrozoobenthos. Penelitian ini bertujuan untuk mendeskripsikan struktur komunitas makrozoobenthos di perairan karst Klapanunggal dan Ciampea, Kabupaten Bogor, Jawa Barat. Pengambilan contoh dilakukan pada bulan Februari hingga April 2015. Pengambilan contoh dilakukan sebanyak tiga kali dengan jarak setiap pengambilan contoh yaitu 2 minggu. Komunitas makrozoobenthos di perairan karst Ciampea dan Klapanunggal terdiri atas kelas Oligochaeta (Lumbriculus sp., Tubifex sp., Peloscolex sp. dan Branchiura sp.) dan Insekta (Ephemerella sp., Tendipes sp. dan Prodiamesa sp.). Jenis makrozoobenthos yang paling banyak ditemukan di perairan karst Klapanunggal dan Ciampea berasal dari kelas Oligochaeta dengan jenis Lumbriculus sp. pada karst Ciampea dan Tubifex sp. pada karst Klapanunggal. Makrozoobenthos dari kelas Oligochaeta dapat hidup di perairan dengan kandungan bahan organik tinggi dan tipe substrat perairan yang halus.

Abstract

Terumbu karang membutuhkan waktu yang lama untuk pulih dan rentan terhadap kerusakan. Penelitian ini bertujuan untuk menganalisis variabilitas spasial tutupan terumbu karang berdasarkan kategori pemanfaatan yang berbeda di Perairan Kepulauan Seribu Utara. Penelitian ini dilaksanakan pada bulan Agustus 2022 di enam stasiun pengambilan sampel di Perairan Kepulauan Seribu Utara. Pengambilan data tutupan karang diestimasi menggunakan metode Line Intercept Transect, sampel kualitas air yang diambil meliputi parameter kecerahan, nitrat, oksigen terlarut, pH, dan salinitas. Kategori pemanfaatan yang berbeda antar-stasiun pengambilan sampel tidak berpengaruh nyata terhadap besar persen tutupan karang hidup, kecuali pada stasiun yang berkategori dilindungi. Penyebab utama yang mempengaruhi nilai persen tutupan terumbu karang antar-stasiun pengambilan sampel diduga karena kerusakan fisik akibat benturan secara langsung dari aktivitas manusia, seperti kegiatan penangkapan, pariwisata, dan transportasi. Tutupan karang tertinggi dengan kategori baik terdapat pada Area Perlindungan Laut, sementara tutupan karang terendah dengan kategori rusak terdapat di Barat Pulau Pramuka sebagai stasiun yang paling terpengaruh oleh aktivitas manusia.

Abstract

Waduk Jatigede yang berdekatan dengan daerah pemukiman dan kegiatan pertanian berpotensi menerima buangan limbah, yang diduga juga mengandung bahan pencemar nitrogen. Peningkatan kandungan nitrogen secara kontinyu dapat memberikan dampak buruk, seperti penurunan kualitas air dan terjadinya eutrofikasi. Analisis daya tampung beban nitrogen di Waduk Jatigede, Jawa Barat ini dilakukan berdasarkan data primer yang dikumpulkan. Pengambilan contoh air dan pengumpulan data perairan Waduk Jatigede dilakukan terhadap enam stasiun pengamatan dan dua sungai utama inlet Waduk Jatigede. Selanjutnya dilakukan penentuan beban nitrogen dari sungai (inlet) dan dalam waduk, sedimentasi nitrogen, serta daya tampung beban nitrogen. Beban nitrogen di Waduk Jatigede sebesar 24.374 ton telah melebihi batas maksimum menurut baku mutu perairan, sebesar 1.739 ton. Sementara, daya tampung beban nitrogen maksimal sesuai dengan baku mutu perairan di Waduk Jatigede adalah sebesar 595 ton. tahun-1. Dapat disimpulkan bahwa Waduk Jatigede sudah tidak mampu lagi menampung beban nitrogen yang masuk.

Abstract

Situ Patengan is designated as a Natural Tourism Park, offering recreational opportunities. However, human activities in the surrounding area can introduce both organic and inorganic materials, leading to changes in the lake’s trophic conditions. The trophic state level, which indicates the presence of nutrients, is used to evaluate the potential for the utilization of water bodies. The aim of this study was to assess the trophic state of Situ Patengan in Bandung Regency, West Java. Water samples were collected from the lake at four locations over three sampling periods. The trophic index (TRIX) method was applied to evaluate the lake’s trophic state. Total phosphate concentrations ranged from 0.041–0.187 mg/L, dissolved inorganic nitrogen concentrations varied between 0.20 and 0.64 mg/L, and chlorophyll-a levels ranged from 10.08 to 33.83 μg/L. According to the TRIX classification, the trophic state of Situ Patengan is considered eutrophic, with values ranging from 4.25 and 6.54. This information is valuable for predicting potential increases in trophic levels and guiding the sustainable management of Situ Patengan ecosystem.

Abstract. Pratiwi NTM, Imran Z, Ayu IP, Iswantari A, Wulandari DY. 2020. The phosphorus load and the variation of the trophic states of Cirata Reservoir (West Java, Indonesia) from 1988 to 2017. Biodiversitas 21: 4176-4183. Cirata Reservoir was constructed in 1987 between Saguling and Jatiluhur Reservoirs; these are the three man-made cascading lakes in West Java, Indonesia. Cirata Reservoir has been used for floating cage aquaculture activities. The high organic content from the remains of the fish pellets raised the phosphorus (P) load, resulting in the eutrophication of the reservoirs. This research was aimed to assess the P load and the variation of the trophic states of the reservoir from year 1988 to 2017. The trophic states and the nutrients’ conditions of the water were determined using Myxophycean Index. Four groups of phytoplankton were found in the reservoir during observation: Cyanophyceae, Chlorophyceae, Bacillariophyceae, and Dinophyceae. In addition, one group was found in a smaller number of observations: Eugolenophyceae. Although the community structure of the phytoplankton has changed, the Cyanophyceae was always dominant in response against the condition of nutrients, especially P. The P load is closely related to the number of floating cages in the reservoir. This evidence showed that Cirata Reservoir tended to be relatively eutrophic. In general, despite that the P load tended to fluctuate, the trophic states of Cirata Reservoir remained dynamic in relatively high conditions; showed by the oligo-mesotrophic state during its first year of operation, then increased to eutrophic and hypertrophic by the next decade. Although the P load tended to decrease, it remains in the eutrophic condition in the recent time.

Abstract

Gathering accurate bathymetric data in shallow coastal waters proves to be difficult due to the environmental issues and operational constraints, especially in a semi-enclosed water like Banten Bay. This research intends to examine the seafloor morphology, in addition to assessing the quality of hydrographic data acquired through the use of single-beam echosounder (Odom Echotrac CV100) around Panjang Island Waters. The main line and cross line surveys of the survey were carried out using RTK-GNSS positioning and tidal corrections using 30 day observations relative to mean sea level. The bathymetric data show a gradual depth transition from 8 m nearshore to more than 20 m offshore. Ridges and basins are evident in the data indicating spatial variability. According to the results of a data quality assessment based on the IHO S-44 standard, 94.07% of data belonged to Order 2, 76.67% to Order 1a/1b, 56.30% to Special Order and 38.52% to Exclusive Order with data errors below 7%. As the above results suggest, the general hydrographic mapping by the dataset is of reliable accuracy, which does not achieve highest accuracy consistently. The study’s main contribution is the demonstration of performance and practical limitations of single beam echosounder surveys in shallow water environment with a quantification of data quality compared to IHO standard. This study provides a validated methodology for low-cost bathymetric mapping of other similar semi-enclosed coastal water.
