Abstract

Indonesia is an archipelago country that is ranked top of the world for its breadth and wealth. More than 75,000 km2 or almost 14% of the world's coral is in Indonesia. The growth of coral reefs in a sea water is strongly influenced by the quality of waters such as chemical oceanographic factors, namely salinity, pH, DO, nitrate and phosphate. The data collection was carried out twice in September and November 2019 in Damas Waters, Trenggalek, East Java. The purpose of this study is to influence the quality of waters on the growth of coral reefs in Damas, Trenggalek, East Java. The sampling method is purposive random sampling that is the determination of the sample with certain considerations. The location points used by 20 stations are spread, namely on artificial reefs, natural coral reefs, open seas and the area around the harbor. Measurements made include in situ water quality with a multiparameter measurement tool, namely AAQ. The results showed the quality of waters in accordance with environmental quality standards with a value of (1) salinity 31.5 - 3.6 (2) pH 7.9 - 8.1 (3) DO> 5 mg / L (4) Nitrate 0.001-0.007 mg / l (5) Phosphate 0.012 - 0.345 mg / L. Correlation value of all components> 0.5 then the relationship of each parameter and coral reef affect each other.

Abstract

Periphyton is an attached biota that lives on a substrate. Seagrass meadows and periphyton associate to form an ecological system. Seagrass meadows provide a place of attachment or habitat for periphyton organisms. Periphyton itself is one of the producers of primary productivity in the waters. Baluran National Park is one of the National Parks in which there are land and water habitats, and is a protected area that has natural and native ecosystems. Data collected to support this research included temperature, salinity, dissolved oxygen, pH, nutrients (nitrate and phosphate), seagrass cover data and periphyton data. Physical and chemical water parameters are taken directly on the spot or in-situ. Data collection on seagrass cover and periphyton samples was carried out using a 50 x 50 cm2 quadrant transect. Periphyton community structure analysis includes abundance, diversity index, diversity index and dominance index. Community structure is calculated to determine the community condition of a particular organism, to see its stability and presence in an area.

Abstract

Coastal ecosystems are very vulnerable to environmental changes, and one of the variables of resilience in coastal areas is wave height. Clungup Beach is one of the beaches located in South Java with the characteristics of high waves. Analysis of wave height forecasting to minimize environmental damage in the future. The wave height forecasting method is carried out by two methods, namely Fisher Tippet-1 and Weibull, with the aim of comparing the results of forecasting the resulting waves and validating the forecast data. The source of wave data for 10 years (2009 - 2018) was obtained from the ECMWF (European Center for Medium-Range Weather Forecasts) website. The results of data analysis show that the wave height of Clungup Beach for a period of 10 years (2009 - 2018) with the highest value in July 2013, namely 2.67 m and the lowest in June 2010 with a value of 2.28 m, which is classified as a wave extreme in accordance with the Regulation of the Head of BMKG No. KEP. 009 of 2010. Wave forecasting with the Fisher Tippet-1 method return period in 2020 is 2.48 m and in the next 50 years (2069) is 2.76 m. Whereas in the Weibull method, the wave value for 2020 is 2.43 m and for the next 50 years (2069) is 3.01 m. The two methods used have the equation that the wave height that will occur in the Clungup Beach area will experience an increase (upward trend). This will be the basis for determining the scenario of coastal area protection, so that the resilience of coastal ecosystems will be well realized.

Abstract

The phylum Coelenterata, class Anthozoa, includes a group of marine living things known as corals. Corals feature a variety of incredibly gorgeous colors and patterns. The majority of the world's more than 70,000 coral species may be found in tropical marine environments. Due to its geographic setting, Indonesia has an extremely high level of coral diversity and is the world's largest exporter of ornamental coral. Demand on the market for natural ornamental corals is now rising, along with trends in the rate of industrial development. Allowing this industrial activity to grow will result in huge exploitation and put the coral reef environment at danger. Therefore, to quickly increase the number of corals, this research examined transplantation methods. The montipora and echinopora genera were the focus of this study. The Montipora capricornis coral sample from PT Tirta Samudra Bali had the highest growth rate of the Montipora genus corals there, with an average growth rate of 1,404 cm2/week. The highest growth rate of the Echinopora genus corals had an average growth rate of 0.362 cm2/week. As they have a 100% survival record, cultivation activities using the transplant method performed at PT. Tirta Samudra Bali are regarded as successful

Abstract

The fisheries sector is one of the sectors with great potential for the Indonesian economy. East Java has a large fishing enterprise, which is due to the spread of fish landing bases and an active role in promoting local fishing production, one of which is the beach fishing port (PPP) Pondokdadap. The aim of this study is to obtain information on the types and volumes of fish production captured in the PPP Pondokdadap in May and June 2022. The method used by the author in conducting this research is a qualitative-descriptive approach. According to the results of research, during May 2022, the production of fish captured in PPP Pondokdadap amounted to 1,813 tonnes. In June, the capture amounted to 1,605 tonnes. There was a decrease in production volume of 207 tonnes, or about 11%. There are 10 species of fish captured, dominated by tuna

Abstract

The fishing port, which acts as a public agency, provides services and facilitates fishing activities for fishermen. One indicator that the service provided is already optimal is the minimum number of vessels in the process of dismantling fish in the port. The study aims to find out the fishing landing system and the number of ships that landed during the period September–August 2022. The method used is directly through field observations and collecting secondary data to supplement the data obtained. The system applied to each port is different. The port of Pondokdadap applies the queue method as well as the system of nahkoda, where the ship's documents must be submitted and the fisherman's number taken before landing. Boats that want to sell fish to the TPI must be equipped with a catch letter. In the period September–August 2022, the highest number of ships was found in June 2022, with 603. For the smallest number in January 2022, there were 22 ships. Based on the results obtained, it is known that the period of April–September has the highest number, while there is a decrease in the number in October–March. There was an increase in the number of vessels that carried out fishing, which was affected by the fishing season, with the high season in the Eastern season.

Abstract

Lift net is a fishing tool that belongs to the lifting net group. In terms of construction, there are two types of lift net, namely: stationary lift net and floating lift net. Stationary lift net are a type of static fishing gear. The advantage of this fishing gear is that it gives fishermen certainty about the fishing location. However, if fishermen are not wise in exploiting fish, the catch will decrease, the reason is that stationary lift net will rely heavily on the stock/abundance of local fish in these waters. This is different from floating lift net which are able to change positions. The method is to pull the lift net with the help of the boat. Usually fishermen will move the position of any lift net when the catch is low or the weather is bad. Thus, research was carried out regarding the effectiveness and efficiency of the operation of the lift net by conducting experimental fishing in Probolinggo waters. The results of the independent t test show a significance value of 0.152, which means there is no difference in catches between the stationary lift net and the floating lift net.

Abstract

Mangrove ecosystems are recognized as vital blue carbon reservoirs that contribute significantly to climate regulation through biomass-based carbon storage. This study assessed mangrove diversity, structure, biomass, and carbon stocks in two key locations: Banyuurip Mangrove Center (BMC) and Lewean Mangrove Park (LMP), located in the Ujungpangkah Estuary, Gresik. Data were collected from 15 rectangular plots (10 × 10 m) to determine species composition, tree density, Importance Value Index (IVI), above and belowground biomass, and estimated carbon stocks using standard allometric equations. A total of 12 mangrove species were identified, with Avicennia marina emerging as the dominant species in all growth stages across both sites. Tree density varied from 100 to 1,600 trees/ha, reflecting stages of regeneration rather than degradation. The highest IVI values were recorded for A. marina (196.3% in BMC; 146% in LMP). Total biomass and estimated carbon stock were higher in BMC (340.48 Mg/ha; 164.87 Mg C/ha) compared to LMP (125.67 Mg/ha; 56.20 Mg C/ha), primarily due to differences in species dominance and stand maturity. These results underline the ecological and climate mitigation significance of maintaining mangrove diversity and biomass. The study supports the integration of mangrove conservation into blue carbon strategies for sustainable coastal management, and recommends strengthening local restoration initiatives based on dominant species performance.
