Abstract

Coral transplantation is a coral rehabilitation activity by cutting coral from a colony to be replanted. This study aimed to determine the differences in the growth of coral transplants of Acropora sp. using cement media and pipe media. Research on coral transplantation was carried out at the end of December 2020 to early March 2021 for 3 months at Pandawa Beach, Bali. Observations of coral growth using different media were carried out 6 times with an interval of 14 days using a caliper. Observations on the growth of coral fragments consisted of increasing the height and width of the coral. The results showed that the coral height of Acropora sp. using pipe media has the highest growth rate of 39.34 mm, coral height growth using cement media is 30.31 mm. The result of the highest growth width on coral using pipe media is 30.90 mm and the growth of coral width on cement media is 28.76 mm. The survival rate of coral Acropora sp. on cement media by 100% and on pipe media by 90%.

Abstract

Ayung River is the longest river in the Bali Island. There are a lot of antropogenic activities around this area. However, there is lack information about the nutrient (Phosphate) level in the water of this river. This study was aimed to observe the amount of nutrient (Phosphate) in the water of Ayung River. Water sampling was carried out in the upstream, middle stream, and downstream of Ayung River from December 2019 to January 2020. The phosphate amount was measured using Hanna HI713 reagent, Dissolved Oxygen (DO) of water was measured using Winkler method, pH of water was measured using digital pH meter, and water temperature was measured using Thermometer. The result showed that phosphate of the water was ranging from 0.3 to 0.9 mg/L. The amount of phosphate tends to be higher in the evening (0.9 mg/L) compared to that in the morning time (0.4 mg/L). The phosphate increase rate of middle stream to the downstream was higher (0.011 mg/L.km) compared to that of upstream to the middle stream (0.009 mg/L.km).

Abstract

This study aims to determine the content of organic carbon, total nitrogen (TN), the total number of bacteria (TB) and the level of decomposition of organic matter in the bottom substrate of shrimp vannamei ponds (Litopenaeus vannamei) in Sanggalangit Village, Gerokgak District, Buleleng, Bali. Organic matter that is constantly accumulating on the pond bottom substrate can reduce the quality of the water. Data was collected in February-May 2019 using purposive sampling method with the number of ponds studied as many as 9 ponds. This research uses quantitative descriptive methods. Measurement of total nitrogen is done using the Indophenol method, organic carbon using the Walkley and Black method and total bacteria using the TPC (Total Plate Count) method. The results of this study obtained an average value of 29.34% organic carbon content, 1.15% total nitrogen and 15.2×106 total bacteria. The level of decomposition of organic matter in vannamei shrimp ponds (Litopenaeus vannamei) in Sanggalangit Village was included in the balanced category (C/N = 29.37). The measured C/N ratio indicates that the decomposition process of organic matter is going well so that the exchange of nutrients from the substrate to the pond water media is going well in supporting the pond productivity.

Abstract

Transplantasi karang merupakan salah satu cara merehabilitasi karang. Transplantasi karang merupakan suatu teknik penanaman karang baru dengan metode fragmentasi. Penelitian ini bertujuan untuk mengetahui perbedaan pertumbuhan karang genus Acropora, Montipora dan Stylophora. Penelitian ini dilakuakan selama 3 bulan, yaitu pada bulan April hingga Juni 2018. Pertumbuhan karang diukur setiap 2 minggu sekali dengan menggunakan alat jangka sorong. Pengamatan pertumbuhan pada fragmen karang dilakukan dengan mengukur dimensi pertumbuhan yang terdiri dari pertambahan lebar dan tinggi karang. Hasil penelitian menunjukan bahwa karang genus Montipora memiliki tingkat pertumbuhan paling tinggi sebesar 1,40 cm kemudian Acropora dengan tingkat pertumbuhan sebesar 1,30 cm dan Stylophora sebesar 1,00 cm. Pertumbuhan lebar karang tertinggi adalah genus Montipora sebesar 1,85 cm, Stylophora dengan nilai 1,46 cm dan yang terendah genus Acropora dengan nilai 1,29 cm. Tingkat kelangsungan hidup karang selama penelitian menunjukan karang dapat bertahan hidup selama 4 minggu dan mulai mengalami penurunan pada 2 minggu penelitian berikutnya. Secara keseluruhan karang genus Acropora dan Stylopora memiliki tingkat kelangsungan hidup tertinggi yaitu 90 %, sedangkan karang genus Montipora memiliki tingkat kelangsungan hidup terendah yaitu 83,3%.

Abstract

Banyuwedang Bay is located in the West Bali National Park (TNBB), which is part of the conservation area. There were a lot of tourism activities developed in this area, which potentially caused disruption of the surrounding water conditions. This study aims to determine the profile of various communities in the waters of Banyuwedang Bay and as initial data to see the development of these communities due to the environmental impacts of various activities in the waters and coastal area of Banyuwedang Bay. Data was collected from five observation stations including: Community structure of Plankton, Macrozoobenthos, and seagrass, and coral reef cover. Result shows that the phytoplankton community consist of 9 genera where Nitzschia sp. (Bacillariophyceae) as the dominant species found. Phytoplankton have low diversity index ranging between 0.348 - 1.411. Zooplankton diversity index also has low value 0.693 with three genera found namely Copepoda sp., Nauplius sp. and Daphnia sp. Macrozoobenthos community is composed of 17 macrozoobenthos genera, with low diversity index ranging ??between 0.562-1.809. There are only two species of seagrass, Halophila ovalis and Cymodocea rotundata, which were found in Banyuwedang Bay. Coral reef cover seems to be ranged from poor to good conditions, with 25% - 73% coverage. Based on the result, we concluded that the Banyuwedang Bay has a moderate condition to the growth of plankton and seagrass, but good for coral reefs. Periodic monitoring is needed to find out changes in conditions that can occur in Banyuwedang Bay. Keywords: Banyuwedang Bay; community structure; macrozoobenthos

Abstract

Mangrove ecosystems have an important role, both for biota and humans. The level of density and mangrove cover is one illustration to determine the level of damage to mangroves. This study aims to determine the species composition and the level of mangrove damage based on the density and percentage of canopy cover of mangroves in Gilimanuk Bay. This research was conducted in February 2021. The determination of the sampling point was carried out using the purposive sampling method. Mangrove data retrieval was performed using a plot 10x10 m2 with a total number of plots were 31 plots. The results showed that there were 11 types of mangroves from 7 different families in Gilimanuk Bay. The most common type of mangrove found was Ceriops tagal (45,84 %) and the least was Xylocarpus granatum (0,13 %). Mangrove density in Gilimanuk Bay is 2390,32 ind/ha, and canopy cover is 83,84%, which shows that the condition of mangroves in Gilimanuk Bay is included in the good category (very dense). Keywords: Mangrove; Gilimanuk Bay; Density; Canopy coverage
