Abstract

Artificial live rock is an artificial live rock that is shaped like living rock in nature. Artificial live rock is designed to mimic natural living rock which is capable of being a substrate for corals, a habitat for epibenthic and the biological filter of a saltwater aquarium.  The purpose of this research is to know the technique of making artificial live rock and the development of artificial live rock that are suitable for export on an export scale. The method used in this research is an experimental method with quantitative descriptive analysis. The level of suitability and product standards uses a simultaneous regression coefficient test analysis or the F test.  The manufacture of artificial live rock does not have a special pattern, but artificial live rock is made as attractive as possible and resembles the shape in nature. Product standardization is carried out by using artificial live rock materials consisting of: 1 kg of pumice stone, ½ kg of cement, ½ kg of sand, 500 grams of calcium and 1.5 liters of water. The type of substrate that is good and ideal for algae on the surface of artificial live rock is an area with a bottom of coral sand mixed with coral rubble. Artificial live rock can be harvested for 3 months in water, with the characteristics of the surface of the artificial live rock covered algae which is then cleaned and placed in a treatment pond before being exported

Abstract

Kranji waters have potential fishing grounds for the development of large marine fisheries. Kranji fishermen often face obstacles in their fishing efforts due to a lack of information about the season and potential fishing areas. The oceanographic factor of the waters can be one of the clues to determining a good catch. The purpose of this study was to determine the condition of the oceanographic parameters of the fishing area, determine the catch rate and determine the correlation of oceanographic parameters to the catch of ring trawlers. The data used in this study were temperature, salinity, depth, current velocity and catch for 10 fishing trips. Oceanographic parameters in the Kranji fishing area for 10 fishing trips were as follows: temperature ranged from 29.9- 31.8°C, water salinity ranged from 29-31.1‰, water depth ranges from 50-70 m and the current velocity ranges from 0.09to 0.34 m/s. The variability of ring trawl production during 10 times of capture found 5 species caught. The variability and composition of purse seine catches were as follows: Tongkol Walang with a percentage of 54.42%, Tongkol Lorek with a percentage of 38.13%, belo fish with a percentage of 6.37%, juwi with a percentage of 0.53%, and the lowest. the percentage is bagong by 0.52%. The correlation of oceanographic parameters with purse seine catches is as follows: Current velocity has the highest correlation value with a correlation coefficient of 0.814. The temperature has a strong category value with a correlation coefficient of 0.756. Salinity has a negative correlation value with a value of -0.658. Depth has a strong category value with a correlation coefficient value of 0.657.

Abstract

The purpose of this study is to determine the rate of shoreline change and the level of abrasion in Bukit Batu District, Bengkalis Regency, Riau Province based on several physical variables in the coastal area. End Point Rate (EPR) is a method that can be used to calculate the rate of shoreline change by displaying transects according to their category (high abrasion, medium abrasion, low abrasion, stable, and accretion). From 1991-2021 there was an abrasion of ±139.71 meters equivalent to ±4.65 m/year which mostly occurred in Sukajadi Village and Pangkalan Jambi Village, while accretion of ±27.51 meters equivalent to ±1.58 m/year mostly occurred in Pakning Asal Village and Sejangat Village. Moderate abrasion is the predominant type. Sukajadi and Pangkalan Jambi are villages that have experienced high levels of abrasion. The area affected by abrasion has moderate and fast currents as well as coastal protection in the form of mangroves, most of which have been damaged and require repairs. Therefore, the main factors causing the abrasion are thought to be the lack of coastal protection and high-speed currents and waves flowing from the Malacca Strait.

Abstract

Narrow barred Spanish mackerel and wolf herring is an important commodity that has commercialized intensively to fulfill the needs of the market, both domestic and export. Research has been conducted from June-August 2020 in Malacca Strait Waters. The purpose of this study is to analyze the dynamics of population parameters such as growth rate, mortality rate, exploitation rates, and recruitment patterns of narrow barred mackerel (Scomberomorus commerson) and wolf herring (Chirocentrus dorab). The sample size of spanish mackerel was taken at random from the purse seiner and gillnet catches. Data of size obtained were used for the analysis of population dynamics parameters. Some population dynamics parameters were estimated using the program FISAT II. Von Bertalanffy growth parameters of spanish mackerel were derived L and growth rate (K),for males 772.8 mm and 0.5/year and for females 979.65 mm and 1,7/year, and wolf herring was derived L and growth rate (K), for males 871.5 mm and 0.59/year and for females 1048.95 mm and 0.65/year, respectively. Total mortality (Z) of Spanish mackerel males and females was 0.61/year and 4.07/year and wolf herring males and females were 0.36/year and 1,3/year. Fishing mortality rate of Spanish mackerel (F) for males and females was 0,13/year and 3.07/year high than the natural mortality rate (M) 0.48/year and 1/year and the wolf herring fishing mortality rate for males and females was 0.16/year and 0.78/year lower than natural mortality rate (M) 0.52/year. Exploitation rate (E) of Spanish mackerel for males and females was 0.21/year and 0.75/year and wolf herring for males and females was 0.44/ year and 0,6/year, that almost full exploitation when compared with the optimum of 0.40. The recruitment pattern of Spanish mackerel for males was (14.59%) in June and for females was (26.84%) in August and wolf herring for males was (16.02) in June and for females was (28.63%) in July.

Abstract

Comet fish (Carassius auratus) is a type of freshwater ornamental fish with a high selling value due to its unique body shape and bright colour. The purpose of this study was to evaluate the effect of different LED (Light Emitting Diode) light colours on colour brightness, growth, and survival of comet fish. This study applies an experimental approach with an experimental design in the form of a completely randomized design (CRD) and consists of 5 light treatments and 3 replications, namely A (room light), B (white LED), C (blue LED), D (green LED), and E (red LED). The results showed that LED light treatment had a significant effect on the colour quality and feed efficiency, but did not significantly affect the growth and survival of comet fish. The best colour quality was found in treatment E (red LED) with an increase in the TCF (Toca Color Finder) score of 6.22 and colour performance on the back by 80.80%, pectoral fin colour by 64.91%, and tail fin by 71 .18%. The best feed efficiency was obtained in treatment C (blue LED) with a feed efficiency value of 57.48%. The behavioural responses of comet fish did not make any difference between each LED treatment. The water quality of the comet fish rearing media has a temperature value ranging from 25.70 – 29.20 C. The pH value ranges from 7.29 to 8.50. Meanwhile, dissolved oxygen ranges from 8.00 – 12.20 mg/L

Abstract

Marine heatwaves (MHWs) are extreme warming events in the ocean when the temperature detected is above the 90th percentile of climatological temperature for at least five consecutive days. MHWs events can extend up to thousand kilometers and have been detected in the subsurface layer. MHWs are described by metrics (frequency, duration, and cumulative intensity). The purpose of this study was to determine the characteristics of MHWs in the subsurface layer for 27 years (1993-2019). The data used in this study is the sea water temperature data of the depth 0,4m-763m from Marine Copernicus Global Ocean Physics and Niño 3.4 indices. The method used in this study is a statistical method to calculate the average and trend of the MHWs metric. The results of this study denotes that the occurrence of MHWs at a depth of 0.4m-92m is caused by ENSO (El Niño Southern Oscillation) positive phase (El Niño) with a delay of 7-8 months and at a depth of 109m-763m caused by negative phase ENSO (La Niña) with a delay of 1-3 months. It was also found that the frequency of MHWs was higher at a depth of 418m-763m with a maximum value is 2,6 events/year, the duration of MHWs was greater at a depth of 0,4m-77 m, with a maximum value of duration is 30-32 days/year, and the maximum cumulative intensity of MHWs events for 27 years is 90˚C. During the 1993-2019, the trend of frequency, duration, and cumulative intensity of MHWs in the subsurface layer of south Java Sea has significantly increased.
