One of biota that compiler coral reefs are soft corals (Octocorallia, Alcyionacea). The aim of this research is to know the soft coral community structure at different depths and the influence of the limiting factors of soft corals. Soft coral data retrieval is done in 3 observation points. Each depth research carried out by installing 6 transects quadrants through 100 meter transect line parallel to the shoreline. Data retrieval of water quality carried out on site research and laboratory testing. The water quality data taken include; temperature, brightness, salinity, pH, flow velocity, DO, depth, nitrate and phosphate. Retrieving data using the soft coral community structure. The highest density values found in every station a depth of 5 meters and the lowest at each station a depth of 15 meters. According to Odum (1971), the value of diversity in the research area included in the high category of H' ? 3.0, as well as to the value of uniformity in the high category at stations 1 and 3 on each depth of H ? 0.6 and at station 2 for each depth in the low category of E ? 0.4. According to Odum (1971), the value of dominance classified in the high category of 0.75 to 1.00, which means that there are species that dominate that Sinularia flexibillis except at a depth of 15 meters which is rated as moderate dominance. The observation of the condition of the community structure is still relatively good, as the limiting factor in the study area is very suitable for soft corals.","PeriodicalId":30849,"journal":{"name":"Journal of Marine and Aquatic Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42337060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tourism potential in the coastal area of Bulak District in Surabaya is expanded. It is shown by the construction of Surabaya Bridge in 2015. This construction will affect land use change. Remote sensing technology is one of the acquisitions to monitor land use change. This research focuses on identifying the land use change in the coastal area in Bulak District, Surabaya, in 2014 and 2020, as well as to determine the accuracy of classification method applied for mapping the land use change in 2020. The application of 2014 acquisitions data was used as the bridge construction plan, while the application of 2020 acquisitions data was used as the premise for the land classification system in the previous year. There are two methods used to classify land use in coastal areas, that is pixel-based classification (maximum likelihood algorithm) and object-based classification (nearest neighbor algorithm). The research shows that there are 6 land use classes in study area: built-up land, rice fields, forests, shrubs, non-built-up land, and ocean. By applying these two methods, the result shows different area changes. The conversion of the highest mainland by applying a pixel-based classification was found in built-up land (+23.03 ha) and rice fields (-24.84 ha), while the area changes by applying object-based classification method were found in built-up land (+32.75 ha) and rice fields (-26.91 ha), respectively. The accuracy by applying the pixel and object-based method is 89% and 92%, respectively, from the percentage indicates good interpretation.","PeriodicalId":30849,"journal":{"name":"Journal of Marine and Aquatic Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42256759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While population of L. olivacea in Kapoposang Island tend to be different compared to other populations. Genetic diversity analysis showed that L. olivacea from western Indonesia are more higher than center Indonesia.

The income generated from shark fishing each trip averages to about Rp 627.714 per boat. Prior to the Covid-19 pandemic, some of the fishermen work jobs in the tourism sector.
