Abstract

Ngurah Rai Forest Park (Tahura) is one of the mangrove ecosystem areas in Bali which is an area of brackish forest type. Ngura Rai Tahura is based on administration in two city districts namely Badung and Denpasar. The Tahurah Ngurah Rai area is surrounded by housing, restaurants, hotels, malls, and shops as centers of community activities that have the potential to cause disruption to the balance of the aquatic ecosystem. The purpose of this research is to determine the diversity of macrozoobenthos and the condition of water quality in the mangrove ecosystem area in Tahura Ngurah Rai, Bali. This research uses a descriptive quantitative method that is exploratory in order to obtain facts of the conditions that exist through surveys in the field and identification in the laboratory. The sampling technique used was purposive sampling with transect quadrant measuring 1 x 1 m with teransek determination area of 5 m x 5 m. Sampling was carried out at four stations which included macrozoobenthos samples, measurement of water quality parameters (temperature, salinity, pH, DO, turbidity), and analysis of water-based substrates performed visually. Data from research conducted at three different locations in the Ngurah Rai Tahura mangrove ecosystem area found 55 species with a total abundance at station 1 6.68 ind / m2, station 2 4.52 ind / m2, station 3 3.55 ind / m2 from the class Gastropoda, Crustacea, Bivalvia, and Polychaeta.. Diversity index at the three stations is classified as moderate level with water conditions that have experienced pressure or disturbance.

Abstract

Availability of rotifera natural food needs to be increased in line with the increasing need for larvae feed in fish hatchery production activities. This study aims to analyze the effect of different feeds on the growth rate of rotifers (Branchionus plicatilis). This research was conducted in December 2018 to January 2019 at the Jepara Brackishwater Aquaculture Center. This study used a completely randomized design with 4 treatments and 3 repetitions, namely control (N. ocullata), treatment 1 (N. ocullata + bread yeast), treatment 2 (N. ocullata + scott emultion), treatment 3 (N. ocullata+ fish powder). The dosages of each feed were 170,000 cells / ind N. ocullata, 0.5 g / 106 rotifera bread yeast per day, 6 µg / ind scott emultion, and 0.3 g /106/ind fish powder. Feeding is done twice a day in the morning and evening. The test plankton used was 15 ind / ml Branchionus plicatilis. Rotifera culture was carried out for 6 days and the population of rotifers was observed every day before feeding. Analysis of water quality was also carried out including DO, salinity, pH, temperature, and ammonia. The rotifera growth rate is analyzed through the number of individuals produced during the culture period. The results showed that treatment 3 (N. ocullata + fish powder) was the best treatment. The results of the ANOVA test showed that different feeding variations for each treatment had a significant effect (P <0.05) on the rotifera growth rate.

Abstract

Benoa Bay is an estuary that gets input of waste and nutrients from six rivers and inderectly influenced water productivity in Benoa Bay. The nutrients flow from the river to domestic, industrial, and agricultural activities into Benoa Bay. The amount of nutrient inputs accumulated in Benoa Bay this could affect the chlorophyll-a consentrations. The purpose of this study was to determine the spatial distribution and influence nitrate and phosphate on chlorophyll-a concentration. Water surface sampling carried out on February 2019. The method used was purposive sampling and chlorophyll-a concentration was analysed using spectrophotometer Shimadzu UV-2600, based on the maximum absorption of four wavelengths (quadrichroic). The results showed that the chlorophyll-a concentration ranged from 0.22 - 8.53 g/m3 with an average of 5.58 g/m3. Nitrate concentration ranged from 0,004 - 0,180 mg/L with an average 0,107 mg/L. Phosphate concentration ranged from 0,005 - 0,229 mg/L with an average 0,101 mg/L. Spatial distributions of chlorophyll-a concentration in Benoa Bay higher in the estuary area compare to sea area. The different concentration of chlorophyll-a in Benoa Bay were affected by physical and biological processes. The result of statistic regression of the nitrate and phosphate influence on chlorophyll-a concentration in Benoa Bay was 39,2% (R² = 0.392) for nitrate, meanwile 20,5% (R² = 0.205) for phosphate.

Abstract

Mangrove ecosystems are able to support biological and ecological life cycles and provide welfare for coastal communities. Pest outbreaks that attack seedlings to mangrove trees often cause ecological losses throughout the TAHURA Ngurah Rai Bali area. The ecological interactions of barnacle pest species in mangrove ecosystems are very complex and highly detailed studies. There is empirical evidence that the attachment of barnacles is strongly associated with allelochemical compounds produced by mangroves. This study aims to inventory the attachment of barnacles (arthropods) to several types of mangroves in the TAHURA Ngurah Rai area of Bali. This study used a purposive sampling method to pay for the location of the observations. Quadrant transects were used to organize the classification of the mangrove plots, barnacle densities being calculated for each transect. The density of barnacles was calculated on the number of barnacles attached to the mangrove plants, then recorded the types of plants attached, types of barnacles, types of planting and the number of individuals for each mangrove classification. The study showed that barnacles planted most of the mangrove seedlings at all stations, while the classification of tree plots only had barnacles attached at station 3. The number of attachments of Amphibalanus sp. the highest was found at station 3 of the R. mucronata tiller classification of 881 individuals, while no attachment of barnacles was found at all stations for S. alba mangroves. Overall, the attachment of barnacles was higher in R. mucronata tillers and had the potential to reduce their growth productivity in the field. Efforts to control barnacles really need to be done to increase the success of planting mangroves in TAHURA Ngurah Rai, Bali.

Abstract

The Seagrass ecosystem is one of the important ecosystems in the ocean in mitigating global warming. This research aims to examine the potential for storing carbon stocks in seagrass biomass. The purposive sampling method was used at three location points. At each location, there are 9 quadrants for a total of 27 quadrants. The types of seagrass found were Thalassia hemprichii, Cymodocea rotundata, Enhalus acoroides, Halodule uninervis, Halophila ovalis, Halodule pinifolia with moderate diversity and moderate community stability. Seagrass conditions are relatively protected between the coast and coral reefs with the highest average density of 225 ind/m2. The type of seagrass with the highest density is Thalassia hemprichii. The types of substrates are sand, coral rubble, and sandy mud. The carbon stock in the Lembongan Beach area has an area of ??89.46 hectares of seagrass beds. Around 56.32% or 3,21 tons of carbon were stored as the bottom carbon stock of the substrate and 43.67% or 2,49 tons of carbon were stored as the top carbon stock of the substrate. Keywords: Thalassia Hemprichii, Seagrass, Substate, Global Warming
