<![CDATA[One of the procedures for rescuing a seaplane after an operational is to secure it, namely by mooring at an available port or mooring at a mooring buoy. This mooring buoy is considered a vehicle necessary for securing seaplanes in coastal conditions where it is not yet possible to build infrastructure in the form of an amphiport. To overcome this problem, seaplanes need to add a mooring cleat at the end of the bow of each float, which attaches the rope to the mooring buoy itself. So, it is necessary to study the strength of the mooring cleat itself when withstanding environmental loads. This study was carried out by modelling the mooring cleat using the finite element method to determine where the most significant stresses occur in the mooring cleat structure. Mooring cleats are modelled on deck thickness with varying thicknesses of 20mm and 40mm. The stress that occurred in the mooring cleat structure is then calculated using the Palmgren-Miner rule to determine the fatigue life of the mooring cleat for each variation. It was found that the largest von Misses stress experienced by the structure using 7075-T6 aluminium material was 147.87 MPa, which occurred in the mooring cleat, which was located on the 20mm deck thickness variation at the portside. Meanwhile, this variation's most extended fatigue life calculation occurred for the 40mm deck thickness variation on the portside with 514.43 years.]]>

<![CDATA[The enactment of Law Number 6 of 2023 concerning the Ratification of Government Regulation in Lieu of Law Number 2 of 2022 on Job Creation into Law requires that any permanent utilization of marine space must have basic permit for marine spatial utilization activities (KKPRL). The process of granting KKPRL permit is carried out by assessing the conformity of activities with the guidelines for zoning water space utilization based on the Regional Spatial Plan issued by the Provincial Government. The lack of information regarding the guidelines for marine space utilization causes applicants for marine space utilization activities to be unaware of the guidelines that can be applied to the location, thus hindering the process of issuing the KKPRL permit. The research aims to design a digitalization system for providing spatial utilization guidelines documents in the work area of BPSPL Makassar, which can be accessed online by marine space utilization stakeholders. This will facilitate checking the conformity of marine space utilization activities and accelerate the process of issuing the KKPRL permit. As an initial step, a digitalization system for marine spatial utilization guidelines was designed for two provinces in the work area of BPSPL Makassar, which have integrated the marine spatial planning and land spatial planning into Regional Spatial Plan (RTRWP), namely South Sulawesi Province and Central Sulawesi Province. This initial design will continue to be developed in line with the availability of RTRWP integration documents in four other provinces within the work area of BPSPL Makassar.

<![CDATA[Indonesia is one of the countries with more water surface than land and, in addition, its territory is located between three plates: the Indo-Australian, the Eurasian and the Pacific. This makes Indonesia a country with high volcanic and seismic activity. The abundant news related to mega-earthquakes has made many Indonesians wary of these phenomena. The Sunda Strait is one of the places where megathrustings are expected to occur, and Banten, being a province located in the ocean of the Sunda Strait, makes the level of vigilance high. The modeling process related to tsunami is a representation that can visualize if a large earthquake occurs and causes a tsunami, especially in the coastal area of Labuan subdistrict. The objective of this research is to determine the temporary evacuation spots in tsunami affected areas using tsunami modeling performed with COMCOT (Cornell Multi-grid Coupled Tsunami Grid). The modeling results obtained a wave height to the shoreline of 15 meters with a period to the shoreline of 60 minutes. Twelve temporary evacuation spots (TES) were determined in this study, 9 of the 12 spots become safe TES because the point has a higher ground level and is out of the inundation range.]]>

<![CDATA[Panimbang sub-district is one of the areas affected by the tsunami in 2018, located directly opposite the Krakatau Volcano and close to the Sunda Strait subduction zone (megathrust), making it an area with a high threat of tsunami levels. This study aims to determine the impact of coastal forests in reducing tsunamis using COMCOT modeling as one of the mitigation efforts. The tsunami generator used uses the worst scenario earthquake that can occur in the Sunda Strait subduction zone area. The results show that the coastal forest in Panimbang sub-district with a width of 380 m can reduce the tsunami velocity by 50% compared to the coastal forest with a width of 30 m. In addition, the manning coefficient (n) value also has an influence in reducing the inundation area, inundation level height, and tsunami velocity.]]>

<![CDATA[Coral reefs are vital ecosystems that support marine biodiversity but face increasing threats from human activities and climate change. Artificial reefs (ARs) are proposed as a mitigation strategy to replicate the functions of natural reefs (NRs). This study compares the effectiveness of ARs and NRs in supporting the abundance of Chaetodontidae indicator fish in Sental Village, Nusa Penida. A quantitative approach was applied using the Underwater Photo Transect (UPT) method to analyze coral cover and the Underwater Visual Census (UVC) to measure Chaetodontidae abundance. Data were collected from ARs, NRs, and Rubble Fields (RFs), representing degraded reef areas. The results showed that ARs had the highest coral cover (36%), followed by NRs (32%) and RFs (5%). Moderate species diversity was observed in ARs (H' = 1,210) and NRs (H' = 0,970), while RFs exhibited low diversity (H' = 0.702) and high dominance (C = 0.726). ARs supported the highest Chaetodontidae abundance (0.34–0.57 ind/m²), indicating healthier coral conditions compared to NRs and RFs. Regression analysis revealed a strong positive relationship between coral cover and Chaetodontidae abundance, with a determination coefficient of R² = 0.9932. The study concluded that ARs effectively support biodiversity and Chaetodontidae abundance, although they do not fully replicate the ecological complexity of NRs. Chaetodon kleinii was identified as the dominant species across all reef types due to its high ecological flexibility. These findings underscore the importance of ARs in coral reef restoration and conservation efforts to maintain marine biodiversity.]]>

<![CDATA[Mangroves are coastal ecosystems that have an important role in maintaining the balance of the coastal environment and are effective carbon absorbers which have an important role in climate regulation. The effects of global warming can be reduced through the absorption of organic carbon from photosynthesis and stored in woody biomass, such as standing mangrove trees. Biomass distribution analysis in mangrove vegetation is needed to understand the condition and distribution of mangrove vegetation in more depth and to reflect the productivity and health of the ecosystem. Nusa Lembongan Bali has the potential and utilization of mangrove ecosystems which have potential flora and fauna that need to be preserved. Method spatial interpolation is an effective approach in analyzing biomass distribution because it is able to overcome the limitations of sample data in large forest areas using deterministic techniques Inverse Distance Weighted (IDW). This research aims to analyze the distribution of mangrove vegetation biomass and assess the level of accuracy of the method spatial interpolation in producing a distribution map of mangrove biomass in Nusa Lembongan, Bali. There are 4 types of mangroves found in Nusa Lembongan that are affordable for research, including: Rhizophora apiculata, Xylocarpus granatum, Bruguiera gymnorrhiza And Sonneratia alba, with 90% having a sandy mud substrate. Nusa Lembongan has good biomass distribution as shown by the mangrove vegetation biomass distribution map which shows a dominant color of green to yellow with an average biomass value of 200 Mg/ha to 300 Mg/ha. The results of the correlation calculation have a significant correlation accuracy value with a value of rCount 0.997 > rTable 0.273 which is shown through the results of correlation calculations that support the results of biomass distribution in mangrove vegetation on Nusa Lembongan Island, Bali.]]>

<![CDATA[Turtles are biota that are included in the protected animal category because they have a high level of threat of extinction due to natural and anthropogenic factors. Turtles spend their time in the open sea and go ashore to lay their eggs each season. The successful hatching of turtle eggs is important as an effort to increase their population. This research aims to see the success rate of hatching of green turtle (Chelonia Mydas) eggs on Bangkaru Island, Banyak Island, Aceh Singkil. This research was carried out from March to June 2024. The research was carried out by observing at the green turtle nesting beach the number of nests, number of eggs, nest meters, percentage of hatched eggs. The method used in this research is a survey (direct observation). In the results of research that has been carried out, the highest percentage of turtle eggs is found in the 6th nest with a percentage of 48%, while the lowest percentage is found in nests 1, 2 and 4 with a percentage of 0%. The high percentage in the 6th nest is estimated because of the location. nest that is suitable for the nest, because the nest is directly exposed to the sun and is far from the ebb and flow of sea water which results in the nest being damp and the temperature of the nest remaining stable, the low hatching rate in nests 1, 2, and 4 is because the nest is close to the nest. The ebb and flow of sea water causes the nest to be flooded with sea water and the nest is not exposed to enough sunlight, which causes the eggs to rot in the nest.]]>

<![CDATA[Abstract The cooling system on a ship's main engine plays a crucial role in maintaining operational temperature stability but often encounters technical issues that can degrade engine performance and risk damage to critical components. This study identifies the factors causing failures in the cooling system of the main engine on KM. God Bless 08, particularly in the heat exchanger and pipeline components. Data were collected through field observations and direct measurements of freshwater and seawater temperatures at various operational points of the engine. The analysis revealed that the cooling system's performance significantly declined due to dirt deposits and corrosion in the capillary pipes, which hindered the efficiency of heat exchange between seawater and freshwater. The findings of this research provide insights for optimizing the cooling system through regular maintenance and component cleaning, essential for preventing overheating and improving the efficiency of the ship's main engine operations.]]>
