Analysis of suitability and carrying capacity of baronang fish (Siganus sp) cultivation in coastal waters of Maros Regency
No full textSiganus sp is one of the leading commodities that have high economic value. Until now, the market demand for Siganus sp continues to increase so that the prospect of its cultivation is very promising. The problem that arises specifically for fishermen in the coastal sub-district of Maros Regency is that there is no data and knowledge about suitable locations for the cultivation of Siganus sp. This study aims to determine the area that is suitable for cultivation of Siganus sp in the coastal district of Maros Regency. Data collection techniques were carried out by literature studies and direct field observations by taking coordinates and measuring oceanographic parameters (temperature, salinity, pH, brightness, dissolved oxygen, depth, current velocity). Water quality data were analyzed by weighting, overlaying and layout using GIS analysis. This research was conducted in the waters of the coastal sub-district of Maros Regency in January-August 2021. The results showed that the location of the suitability of Siganus sp aquaculture waters in the coastal sub-district of Maros Regency obtained suitable waters (S) for the development of Siganus sp cultivation covering an area of 630.36 ha and waters that are not suitable (N) for the development of cultivation Siganus sp covering an area of 681.2 ha

The social construction of fisherwomen towards underage marriage in Sulaa Village, Betoambari District, Bau-Bau City, Southeast Sulawesi
No full textThe practice of underage marriage to fisherwomen is based on the socio-economic and cultural conditions of the community in constructing a social phenomenon. Underage marriage is a classic discourse that has occurred in society, both in urban, rural and coastal communities. Communities that practice underage marriages are usually influenced by the constructs that develop in the surrounding community. This paper uses a type of qualitative research with a purposive sampling approach. The type of research used is descriptive, based on case study research and documents (both printed and electronic), as well as other sources of information deemed relevant. The results of the study show that the practice of underage marriage occurs because of habitus or habits that are produced from the low economic conditions of fishing families so that underage marriage is considered as a solution for survival and also as social capital and cultural capital owned by fishing families, as well as the practice of buying age and the strength of religious knowledge is a supporting factor for the practice of underage marriages occurring in the area

Community structure of the Fiddler Crab (Uca spp.) at Bahak Indah Beach, Tongas, Probolinggo – East Java
No full textThe fiddler crab (Uca spp.) is a type of animal belonging to the crustacean group that lives on the coast of Bahak Indah, Tongas, Probolinggo. The high level of anthropogenic activity on the beach of Bahak Indah makes the fiddler crab community increasingly depressed and its habitat decreasing. The purpose of this study was to compare the community structure of fiddler crabs at Bahak Beach, Tongas, Probolinggo. The study was conducted in January – February 2022. The determination of observation stations was purposive based on the consideration of the presence and absence of mangrove vegetation. Sampling of fiddler crabs used a systematic sampling method using transects and plots. Community structure data analysis includes diversity, uniformity, and dominance indices displayed in graphical form. Based on the results of the study found 4 types of fiddler crabs in Bahak Indah Beach, namely Uca cryptica, Uca perplexa, Uca coarctata, and Uca dussumieri. The value of diversity on the beach with mangrove habitat is in the medium category, while on the beach habitat without mangrove vegetation it is in the low category. The uniformity value obtained in mangrove habitats is in the high category, while in coastal habitats without mangrove vegetation it is found in the medium category. On the other hand, the dominance index value is in the low category in coastal habitats with mangrove vegetation, and the moderate category in coastal habitats without mangrove vegetation. The relationship between the Diversity (H') of the fiddler crab and the environmental conditions of the Bahak Indah Beach waters is that it has a positive correlation with water pH parameters with sufficient correlation and soil pH with a strong correlation. While the correlation with temperature parameters is strong but negative. Likewise, salinity is quite strong but negative
The rate of regeneration of mangrove ecosystems on post-bauxite mining areas in the waters of Sei Carang, Tanjungpinang City
No full textThe mangrove ecosystem in the Sei Carang estuary waters, Tanjungpinang city is a mangrove ecosystem that has land conversion activities and leaves the environment with open land. The purpose of this study was to determine the density and regeneration rate of mangrove ecosystems on post-bauxite mining areas as seen from seedling, sapling, and trees. This research was conducted in July-October 2022. This study was conducted at four stations determined by the purposive sampling method, based on the existence of a mangrove ecosystem in which there are post-bauxite mine openings in the Sei Carang estuary waters, Tanjungpinang City. For each station, 3 plots of data were collected, with a plot size of 1x1m for the seedling category, a plot of 5x5m for sampling and a plot of 10x10m for trees. Data analysis used the formula for species density, for the regeneration rate by comparing the data from the calculation of the density of seedling, sapling and trees and then the formula for the diversity index. The results of the study found eight types of mangroves, namely Rhizophora apiculata, Rhizophora mucronata, Bruguiera gymnorhiza, Soneratia alba, Avicennia lanata, Nypa fruticans, and Lumnitzera litorea. Density values at station 1 for seedling 40,000 individual/Ha, sapling 2,667 individual/Ha, and trees 1,533 individual/Ha, at station 2 for seedling 30,000 individual/Ha, sapling 1,467 individual/Ha, and trees 500 individual/Ha, at station 3 for seedling 36,667 individual/Ha, sapling 5,200 individual/Ha, and trees 1,600 individual/Ha then at station 4 for seedling 53,333 individual/Ha, sapling 3,200 individual/Ha, and trees 2,133 individual/Ha. The level of mangrove regeneration at all observation stations is quite good

DNA damage and shell malformation in Blue Mussel, Mytilus edulis
No full textPollutants in waters that cause DNA damage, such as tributyltin, have been known to cause malformations in the mussel shell, which need attention to be studied. Shell malformations or deformities of blue mussels were observed in Norsminde Fjord harbour. The mean shell thickness index of blue mussels from the polluted site was greater than it from expected clean waters. DNA damages detected using the versatile comet assay which expressed as tail length and olive tail moment were evaluated in blue mussels gill cells both in situ and in vitro. The results showed that the average of DNA damages in treatments, namely the polluted site, tributyltin chloride (TBTC) (10 g/l), and hydrogen peroxide (H2O2) (10 M) were different from the expected unpolluted site. Although comet assay is considered as an unspecific assay, the results proposed the similarity of DNA damage character of blue mussel gill cells when exposed to tributyltin chloride and taken directly from the polluted site. The data obtained are important for assessing the environmental risks created by genotoxic agents, e.g. tributyltin, used as antifouling agents in marine paints
Utilization of tuna innards as raw material for making fish feed based on organoleptic
No full textTuna is one of the abundant potentials in North Halmahera Regency, Tobelo. Tuna fish sold in several markets in the city of Tobelo in the form of intact or have been handled, thus tuna fish waste in the form of innards and gills is not utilized, causing a pungent odor at the sales location. The use of fish waste, one of which is an innards fish can be used as an alternative raw material for making fish feed. The raw material for making fish feed must have good nutritional quality including protein sources. This study aims to find out how to process tuna waste into fish feed and the level of respondent's preference for fish feed made. This research was conducted in October - November 2021. The results show that the average panelist assessment of the texture of artificial fish feed texture ranges from 5.45-6.4, the organoleptic value of artificial fish feed ranges from 5.15 to 5.7, the organoleptic value of artificial fish feed ranges from 5.2 to 5.65
