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.

Bawean waters, located in the Java Sea about 150 km north of Gresik, East Java Province, have complex oceanographic characteristics that are interesting to study. The biodiversity and oceanographic conditions of its waters are influenced by hydrodynamic factors, such as ocean currents, tides, and other physical and chemical parameters. This study aims to analyze the oceanographic characteristics of the waters around Bawean Island based on the parameters of temperature, salinity, density, conductivity, and sound speed that play a role in the dynamics of the water mass. Measurements were made using CTD (Conductivity, Temperature, and Depth) instruments with the Direct Reading method, which allows real-time analysis of water masses. The data obtained was then processed using Ocean Data View (ODV) software to identify the distribution patterns of oceanographic parameters. In addition, Surfer software was used in modeling the three-dimensional visualization of oceanographic parameter density distribution patterns. The study sites were categorized into three zones, namely near land, far land, and perpendicular to land, to understand the differences in parameter distribution in different areas. The results showed that the water temperature was in the range of 28.75°C-31.25°C, salinity 26-33.1 PSU, conductivity 45-55 µS/cm, density 1016-1021 kg/m³, and sound speed 1534-1543 m/s. The modeling results and contour maps show that there is a connected density distribution pattern from the causation of low temperature parameters that affect the increase in salinity, conductivity, density, and decrease in sound speed. In addition, this research is expected to provide an in-depth understanding of the distribution patterns, distribution of oceanographic parameters in the waters of Bawean Island and the influence of factors that affect them.

The province of Lampung is one that utilizes fish resources of up to 380,000 tons per year of the total fish stocks landed in existing fishing ports. One of them is the Lempasing Fishing Port Beach (PPP), which has a strategic location and directly borders the Gulf of Lampung. However, according to the annual report of PPP Lempasing from 2013 to 2022, landed catches tend to decrease every year. Therefore, it is necessary to make maximum use of fish resources. In this study, fish stocks were analyzed using the surplus production approach using the equilibrium state method, the Schaefer 1954 model, and the Fox 1970 model, and then the non-equilibrium state model, the Walter-Hilborn 1976 model, in one and two ways. From the results of the analysis it was found that the correct model for determining the level of utilization and catch status used the Walter-Hilborn model of the second way which has the second highest R2 value which reaches 80% and for the highest value of R2 obtained the model Walter- Hilbron one way reaches 95% but with the utilization rate of 313% this is less relevant because it does not correspond to the facts on the field, in this case the utilizing rate in PPP Lempasing according to the Walter -Hilborne model of second way reached 97% which means fully exploited recommended in utilizing the fish resources can refer to the value (YMSY) 713 tons/year, maximum catch effort (FMSY), of 1240 tons/ year, with the number of allowed catches (YJTB) of 571 trips/year in which each trip (UMSY) can catch as much as 0.58 catches. In this case, too, the catch effort can be increased, but by considering the value of the sustainable stock or fish stocks that exist at the depth of Be 727 tons

Pendataan hasil tangkapan merupakan salah satu aktivitas untuk mengetahui jumlah dan jenis ikan hasil tangkapan dari suatu kapal perikanan. Kegiatan ini dilakukan untuk mendapatkan data yang realistik terkait hasil tangkapan yang didaratkan sehingga data yang didapatkan dapat digunakan oleh Pelabuhan Perikanan sebagai pembanding logbook yang diserahkan oleh pihak kapal, sehingga didapatkan data produktivitas yang akurat. Optimalisasi kinerja petugas pendataan akan meningkatkan efektivitas, struktur dan tugas organisasi pelaksana pendataan. Berdasarkan hal tersebut maka dalam penelitian ini akan menganalisis bagaimana kinerja sistem pendataan hasil tangkapan ikan yang didaratkan di PPN Karangantu dan merekomendasikan saran tindakan perbaikan sistem pendataan hasil tangkapan ikan di PPN Karangantu. Hasil penelitian yang didapatkan adalah pada tahap analisis sudah dilakukan wawancara dengan nelayan, enumerator dan syahbandar PPN Karangantu. Standar Operasional Prosedur (SOP) yang digunakan di PPN Karangantu adalah sudah sesuai dengan SOP yang berlaku secara nasional yaitu Direktorat Jenderal Perikanan Tangkap, Direktorat Pelabuhan Perikanan, dengan pengadopsian dan modifikasi SOP sehingga terjadi penyesuaian SOP yang diberlakukan di PPN Karangantu. Ditemukan beberapa kekurangan pada sistem pendataan yang sudah diterapkan di PPN Karangantu beberapa di antaranya yaitu terbatasnya Sumber Daya Manusia (SDM) untuk mendata ke lokasi-lokasi pendataan hasil tangkapan yang didaratkan di luar Tempat Pendaratan Ikan (TPI). Potensi atau saran untuk efisiensi pendataan hasil tangkap di PPN Karangantu adalah adanya aplikasi yang dapat mengidentifikasi jenis ikan untuk entry pendataan yang diikuti hasil penimbangan berkaitan dengan efisiensi waktu sehingga dapat mengurangi delay.

The Karangantu Archipelagic Fisheries Port, commonly referred to as PPN Karangantu, provides a venue for business activities in the field of fisheries. These business activities are carried out by the fishermen of the Boat Lift Net. The Boat Lift Net captures small pelagic fish, and the catch is distributed by the fishermen of the Boat Lift Net at PPN Karangantu to fish traders outside the Karangantu location. This expands the distribution of the marketing of the catch from PPN Karangantu, as it is not only marketed at the Karangantu Fish Auction (TPI Karangantu). Therefore, the objective of this research is to illustrate the map of the distribution locations of the marketing of the catch from the Boat Lift Net landed at PPN Karangantu. Subsequently, it aims to identify the distribution channels for the marketing of the catch from Boat Lift Net at PPN Karangantu. To achieve these objectives, this research uses a qualitative descriptive approach and Geographic Information System (GIS) with remote sensing methods. As a result, it is found that PPN Karangantu has 4 distribution channels and there are 11 distribution locations for the marketing of the catch from the Boat Lift Net
