Abstract

Sanur Beach is one of the tourist destinations that is often visited by national or international tourists. The number of tourism activities can increase pollutants entering the waters, one of which is heavy metals. Heavy metal content in waters can come from various sources of activity, one of which is lead (Pb) and cadmium (Cd). Seagrass E. acoroides are found in the waters of Sanur Beach. Seagrass can absorb heavy metals because it interacts directly with the column to absorb metal ions in the water. The purpose of this study was to determine the value of bioconcentration and translocation factors for the heavy metal content of cadmium (Cd) and lead (Pb) in E. acoroides seagrass in the waters of Segara Ayu Beach, Semawang Beach, and Mertasari Beach and to determine their suitability with the quality standards of the Bali Governor Regulation. No. 16 of 2016, Permenkes RI. No. 32 of 2017 and SEPA of 2000. Sampling was carried out by purposive sampling method and the data obtained were analyzed using quantitative descriptive methods and methods. The highest bioconcentration factor in cadmium (Cd) leaves was at station II, namely 1.91 mg/kg, and the lowest was at station I with a value of 0.62 mg/kg. The highest bioconcentration factor in lead (Pb) leaves was at station II, namely,0.47 mg/kg and the lowest was at station I, namely 0.08 mg/kg. The highest bioconcentration factor in cadmium (Cd) roots was at station II, namely 1.23 mg/kg, and the lowest was at station III, namely 0.73 mg/kg. The highest bioconcentration factor in lead (Pb) root was at station II, namely 0.22 mg/kg and the lowest was at station III, namely 0.10 mg/kg. The highest translocation factor for cadmium (Cd) was at station II, namely 1.55 mg/kg, and the lowest at station I was 0.53 mg/kg, while for lead (Pb) the highest was found at station III, namely 2.45 mg/kg and the lowest was at station I which was 0.49 mg/kg. The content of cadmium (Cd) and lead (Pb) in seagrass does not meet the quality standards of the Bali Governor Regulation No. 16 of 2016, Permenkes RI. No 32 of 2017, but in sediments according to SEPA 2000.

Abstract

Aquatic organisms or nekton have an important role in supporting the stability of the aquatic environment and human life. This study aims to determine the nekton type community, ecological index, and their conservation status in the Unda River area and around Jumpai Beach, Klungkung Regency, Bali. The study was conducted in July - August 2020. The study was conducted in 2 communities, namely Macrozoobenthos and Nekton. Macrozoobenthos samples were collected using the quadratic method in the Jumpai Beach area and the direct observation method along the Unda River. Nekton communities are collected through primary data using "survey methods" and secondary data through interviews with fishermen and local communities. The ecological index data were analyzed using the Shannon-Weiner diversity index (H'), dominance index (C), and uniformity index (E), while the data on Nekton type and conservation status were analyzed descriptively. The nekton species community in the waters of the Unda River and Jumpai Beach areas was obtained as many as 26 species in 21 families which were dominated by Kepala Timah (Aplocheilus panchax) and sepat rawa (Trichogaster trichopterus), while Nautica sp for the Macrozoobenthos community. The ecological index of the aquatic community is the Shannon-Weiner Diversity Index (H') value of 2.98 (moderate), the wealth index (R) of 3.95 (moderate), and the evenness index (E) of 1.21. (High). The highest percentage ratio of nekton communities was obtained by the Macrozoobenthos community, namely 53%, while the nekton species was 46%. Conservation status shows that 13 species are included in the LC (Least Concern) category, 12 species are included in the NE (Not Evaluated) category, and 1 species are included in the VU (Vulnerable) category.

Abstract

Cangkir and Pakerisan are two rivers which are located in Gianyar-Bali Regency, each with a length of 23 km (54.58 km2 of watershed area) and 34.5 km (58.33 km2 of watershed area). These two rivers empties into Lebih Beach that each has a species diversity and abiotic factors. At the upstream of the rivers were occupied by tourism activities that can affect the ecosystem. This study aims to determine the diversity and distribution of macroinvertebrates in the two rivers. Sampling stations were situated at upstream area with 5 stations and 3 replications (15 points) on each river. Sample identification was carried out at the Laboratory of Water Resources Management, Faculty of Marine Science and Fisheries, Udayana University. It was found four species, namely Littorina carinifera, Melanoides torulosa, Parathelphusa convexa, and Bellamya javanica. At upstream of Cangkir and Pakerisan rivers had species of random category distribution pattern with the Morisita Distribution Index value that equal to one. Physical and chemical factors had a major influence on the ecological conditions of the two rivers. The environmental conditions that consisting of substrate type, several physical and chemical parameters were unable to support the life of various biota species found in these aquatic ecosystems.

Abstract

Pantai Mengiat Nusa Dua, Bali merupakan salah satu pantai yang memiliki ekosistem padang lamun dengan keanekaragaman makrozoobenthos yang melimpah. Padang lamun (Seagrass) merupakan tumbuhan tingkat tinggi dan berbunga (Angiospermae) yang hidup terendam pada dasar perairan laut dangkal. Salah satu kelompok biota laut yang sering dijumpai pada kawasan padang lamun adalah jenis makrozoobenthos. Penelitian ini dilaksanakan pada bulan Januari - Maret 2021. Tujuan penelitian ini adalah untuk mengetahui kerapatan ekosistem lamun, kelimpahan makrozoobenthos serta hubungan kerapatan lamun dengan kelimpahan makrozoobenthos di Perairan Pantai Mengiat Nusa Dua, Bali. Sampel lamun dan makrozoobenthos diambil menggunakan transek kuadrat berukuran 0,5 x 0,5 m dengan 30 titik pada 3 stasiun dengan jarak 20 m antar titik. Spesies lamun yang ditemukan di Pantai Mengiat membentuk vegetasi campuran dengan 7 spesies lamun dengan kerapatan jenis tertinggi ditemukan pada Cymodocea rotundata. Makrozoobenthos yang ditemukan pada penelitian ini meliputi 1 spesies dari Kelas Bivalvia dan 14 spesies dari Kelas Gastropoda. Hubungan kerapatan lamun dengan kelimpahan makrozoobenthos menunjukkan hubungan yang kuat dengan nilai korelasi -0,765 dan menunjukkan arah negatif (-), dimana semakin tinggi nilai kerapatan lamun maka kelimpahan makrozoobenthos akan semakin rendah.
