Abstract

Genetic structure and phylogeni of 37 sequences control region DNA mitochondrial cytocrome oxidase I of yellowfin tuna (Thunnus albacores) have been downloaded from GeneBank and analised using Maximum Likehood (ML), Pairwise Genetic Distance and Bootstrapping Phylogeni Model of Kimura 2 Parameter. The result shows that the corrected value of the data was 5,5% and the mean of genetic distances was 3,7 %, where the shortest distance was 0.0% and the longest was 5%. The genetic distances with the out group (Thunnus obesus) ranged between 7,8 % – 9,8 % and with the Thunnus thynus ranged between 10,4% – 12,5%. The value of bootstrap phylogeny of 37 sequences of yellowfin tuna was less than 50%. All those results shows that there was no significant genetic differences of 34 samples sourced from Philipines and 3 from Spain based on sequence region DNA mitochondrial cytocrome oxidase I.

Abstract

A study on water quality of some rivers in Badung Regency (Dangkang River inBeringkit, Penet River in Ayunan, Mati River in Kuta, as well as Ayung River in Carang Sariand Bongkasa) was carried out in dry and wet seasons 2002. Aim of the study is to find thewater quality of those rivers benchmarked with Governor of Bali decree (decision) No.515/2000.Results of the study showed that water quality of Mati River is the worst. There areseven parameters in this river which did not pass the benchmark, namely odor, taste,phosphate, DO, fat, Fecal coli (E. coli) and coliform. Meanwhile, Ayung river had threeparameters (phosphate, fat and TDS), and Penet as well as Dangkang Rivers had twoparameters only (phosphate and fat) which didi not pass the benchmark. Water from all riverare found to be polluted by phosphate and fat either during dry or wet seasons.

Abstract

The Unda River (Tukad) is the second largest river in Bali Province after the Ayung River. The Unda River has been used for various activities, such as tourism activities for white water rafting and agricultural irrigation activities. In addition, Unda River water is planned to be used as a raw water source in the planned construction of the Bali Cultural Center (PKB) which is planned to be built in the lower reaches of the Unda River. Therefore, it is necessary to conduct research related to the water quality of the Unda River, especially in the Lower Unda River. Water quality analysis refers to class II water quality standards according to the Bali Governor Regulation Number 16 of 2016. Meanwhile, the analysis of water quality status uses the pollution index (IP) according to the Decree of the Minister of the Environment Number 115 of 2003. The results of the analysis show that water quality parameters that exceed the highest quality standard is downstream (sampling point 3) with 4 (four) parameters, namely Total Dissolved Solid (TDS), chemical oxygen demand (COD), total coliform and fecal coli. While the sampling points 1 (one) and 2 (two), the parameters that exceed the quality standard are total coliform and fecal coli. In addition, the results of this study also show that the pollution index value downstream is increasing, where at sampling point 1 which is a DAM location has a pollutant index of 3.78 (light pollution) and at sampling point 2 of 6.27 (moderate pollution) and at sampling point 3 of 7.67 (medium polluted).

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.
