Tsunami that swept the Tanjung Lesung coast in 2018 caused Anak Krakatau to collapse in Sunda Strait which hit the coastal areas of Banten and Lampung. Tanjung Lesung is one of the worst areas affected. Tsunami in Tanjung Lesung has taken lives, damaged infrastructure, and caused terrible natural damage. One of the damages affecting residents' lives in the Tanjung Lesung coastal community is exposure to the marine ecosystem. The main ecosystem that has the highest productivity level is the coral reef. Coral biota is the main benthic biota of reefs that are directly affected by earthquakes and tsunamis. However, until now there has been no data on the status of coral reefs after the 2018 Sunda Strait tsunami. Therefore, researchers feel the urgency of this research is high enough to determine the condition of coral reefs after the Sunda Strait tsunami in Tanjung Lesung. There are 3 research stations for data collection before the tsunami, and we conduct research in those 3 stations again after the tsunami. Then we added 3 research stations again, so there are 6 research stations. Observation of coral reefs uses the Line Intercept Transect (LIT) method. The line transect is made by stretching a roll meter with a scale parallel to the coastline along 25 meters with three replications with an interval of about 0-5 meters between replications so the total observed transect was 75 meters. The deterioration of coral reef conditions at three research stations (1-3) proved that the tsunami waves affected the damage to coral reefs. This has an impact on the diversity of coral reef species inhabitants that have decreased. Disturbance form coral-damaged structure and composition changes of the base substrate as habitat can have an impact on reef fish and coral reef inhabitants. So that this research is expected to be a reference for policymakers in determining rehabilitation steps for areas affected by the 2018 Sunda Strait tsunami.

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.

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.

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.
