Abstract

The coral reef ecosystem is a diverse ecosystem that provides coastal protection, food sources, and raw materials for medicine, among other ecosystem services. Coral reef research in Penuktukan, Bali, is fundamental given its urgency in preserving the biodiversity and health of existing marine ecosystems. However, the condition of coral reefs in Penuktukan has yet to be widely studied. Hence, information on species diversity, health conditions, and the impact of environmental change and human activities on this ecosystem still needs to be explored. This research is aimed at fill these data gaps by evaluate the health status of coral reefs, identifying species present, and assessing the impacts of environmental and anthropogenic factors on coral reefs in Penuktukan. The study was conducted at eight observation stations to represent differences in environmental characteristics in July 2023. Field observations were conducted to measure water parameters, and underwater Photo Transects were used to determine the percentage of live coral cover. The results obtained on average water parameters include a temperature of 26.4 ° C, a salinity of 32.7‰, a pH meter of 7.7, a brightness of 3 meters, a depth of 3 meters, and 7 meters depth of 7 meters. This study identified coral massive (CM), coral encrusted (CE), and coralfoliose (CF), which were the most prevalent life forms in Penuktukan Village. The average percentage of live coral reefs in Penuktukan Village was 30.42 %, which suggests that coral reefs in Penuktukan Village Waters are in a medium condition, which is suitable for supporting coral reef ecosystem resilience and development.

Abstract

Mukomuko Regency is one of Bengkulu Province's regencies with abundant marine resources. It has a fishing port, one of which is the Ipuh sub-district fishing port and the Teramangjaya sub-district fishing port. This study aimed to determine the size, length, weight, and composition of shark species landed at the Mukomuko Regency fishing port to identify the types of sharks that are protected based on the IUCN conservation status and the suitability of shark catches. The survey method was used to visit the research location at the ship's landing port, measure the length and weight of the sharks, and take pictures of them. The results of the sharks obtained were two species of sharks, namely the kejen shark (Loxodon Macrorhinus) with a status of almost threatened NT, 35 were found, and the Hammerhead Shark (Sphyrna lewini) with a status of very threatened CR, 15 were found. Of all the types of sharks caught, they were still juveniles and not yet suitable for catch.

Abstract

Ecological conditions are shifting due to increased anthropogenic activities along coastal areas. These activities are affecting the life cycle of aquatic organisms, especially phytoplankton. This study, conducted in the unique ecosystem of Hurun Bay Lampung, aims to analyze the composition and structure of phytoplankton communities in eutrophic waters and water quality conditions. Sampling was conducted in two different months, August and October, by vertical hauling from a depth of 5 meters to the surface. The results revealed a rich diversity of phytoplankton, with 72 genera, 48 families, and 6 classes identified in August, and 55 genera, 42 families, and 6 classes identified in October. The diatom group was the most prevalent, accounting for over 90% of the total, with the highest abundance found in Skeletonema and Chaetoceros. The diversity, uniformity, and dominance indices were all in the low to medium category, indicating a balanced ecosystem

Abstract

The Automatic Identification System (AIS) has become a crucial technology in maritime operations, significantly enhancing navigational safety, maritime surveillance, environmental monitoring, and search and rescue (SAR) efforts. This paper aims to review the diverse applications, challenges, and limitations of AIS within these fields. By analyzing existing literature and case studies, the paper highlights the effectiveness of AIS in improving maritime safety and security while also identifying its shortcomings, such as signal manipulation, coverage gaps, and data overload. The methods include a comprehensive review of AIS applications across various maritime sectors such as navigational safety and collision avoidance, maritime surveillance and security, environmental protection, and search and rescue (SAR) operations by examining both the benefits and the technical challenges. The results indicate that while AIS has revolutionized maritime operations by providing real-time tracking and enhanced situational awareness, ongoing issues such as data reliability and system vulnerabilities require further attention. This review concludes that continued advancements in AIS technology and its integration with other systems are essential to overcoming these challenges and maximizing the potential of AIS in global maritime practices.

Abstract

The needs of society related to the energy crisis require alternative energy that can replace fossil fuels, such as Ketapang seed biodiesel. Preparation of crude oil by maceration method and making biodiesel through esterification and transesterification process. The research will discuss the performance of diesel engines with biodiesel fuel and Ketapang seed biodiesel with the composition of B0, B10, B20, B30. The test uses a rotation variation of 1200 to 2000 RPM and a load of 1000 to 3000. From the test properties and performance test research, it can be seen that they are related to each other. Biodiesel obtained better performance compared to B10, B20, B30. The lowest Specific Fuel Oil Consumption value is found in biodiesel fuel, where based on the average calculation on the maximum Specific Fuel Oil Consumption graph, B0 fuel produces a lower Specific Fuel Oil Consumption value than B10, B20 and B30 fuels with a difference of 33,759 gr/kWh, 49,661 gr/kWh and 113,694 gr/kWh. In this research process, the results of diesel engine performance using Ketapang seed biodiesel proved to be worse than biodiesel.

Abstract

An offshore aquaculture model called OFITS has been designed to be installed in the Indonesia Ocean. The OFITS structure consists of an underwater fish cage and living quarters at the superstructure. An asymmetric mooring line arrangement is proposed to be applied at OFITS. This paper aims to analyze the integrity and safety factor of the asymmetric mooring line arrangement used on OFITS in the presence of environmental load. The proposed asymmetric mooring line arrangement has 14 lines with a specified configuration. There are 10 mooring lines installed on the front side in line with the incoming waves and 4 others installed behind the cage. A nylon line with a diameter of 42 mm and a length of 70 m is used as the mooring line attached to a steel anchor weighing 0.25 tons. The analysis method for the moored cage motion uses the time domain analysis. The mooring line's integrity analysis results show that the maximum tension result is 18.55 tons, with a safety factor of 2.07. It can be concluded that the proposed asymmetric arrangement mooring has good integrity and meets the safety factor requirements of the DNVGL standard, with a minimum safety factor of 1.45.
