    Abstract: Indonesia is known as one of the world's marine biodiversity centers with its rich coral reefs. Coral growth depends on environmental conditions, which in reality do not always remain due to disruptions originating from nature or human activities. The growth of coral reefs in a sea water is strongly influenced by the quality of its 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 waters of Damas Beach are located in Karanggandu Village, Watulimo District. The purpose of this study was to determine the condition of coral reefs in Damas Waters, to determine the effect of water quality on artificial reefs in chemistry in Damas Waters and to determine the relationship of quality parameters of chemical waters with artificial coral reefs in Damas Waters, Trenggalek, East Java. The sampling method is done by purposive random sampling that is determining 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 obtained that in all stations found good water conditions for the life of coral reefs, and also the analysis of the relationship of each parameter and coral reefs influence each other.

    Abstract: Damage to coral reefs is generally caused by destructive fishing activities, they were the usega of explosives, cyanide toxic materials, coral mining for building materials, anchor boat anchors, and the results of sedimentation. Efforts to speed up the process of coral reef recovery, several methods of rehabilitation that can be done include coral transplantation and sinking of artificial reefs. The artificial reef is an alternative to reduce the pressure caused by fishing and destruction of natural coral reefs through the creation of new productive fishing grounds. The purpose of this study was to determine the relationship of water parameters (physical oceanography) for biota around artificial reefs based on Geographic Information Systems. The results of identification of oceanographic parameters in the waters of Damas Beach, Trenggalek Regency consist of: (a). depths range from 0-45 meters, (b). brightness ranges from 2 - 6 meters, (c). water temperature ranges from 25.18-29.59ºC, (d). water turbidity ranges from 0.3-4.32 NTU, (e). type of substrate base waters of Damas Beach fine black sand, (f). current speed ranges from 0.1-0.4 m/s, (h). the average wave height of Damas Beach in the morning, afternoon and evening is 5.6 cm, 8.14 cm and 6.2 cm, (i). the total suspended solid waters of Damas Beach range from 35-351 mg/L. The physical oceanographic parameters are still safe for the growth and development of biota in the waters of Damas Beach, Trenggalek Regency.

    Abstract: Plastic is one of the most common pollutants found in marine waters. The direct negative impact of plastic waste on marine organisms is causing blockages in the digestive tract if eaten either intentionally or unintentionally. One of the efforts to reduce plastic waste is to build public awareness and readiness to actively participate in solving the problem of plastic waste. Therefore, Marine Science Study Program, FFMS, Universitas Brawijaya is dedicated to provide education about the dangers of plastic waste for aquatic communities and marine biota at a pioneering nature school for the Bajulmati Sea Turtle Conservation (BSTC) community in Bajulmati Beach, Malang Regency, East Java. In general, community service activities take place in online and offline manner. The educational methods given to students are a participatory and collaborative learning method, namely by providing an understanding of the material through class discussions and practical waste sorting activities in the field. The results of educational activities on the dangers of plastic waste can increase public knowledge and awareness, especially students at the BSTC nature school so that later it will have an effect on wiser plastic use behavior. Through this activity, it is expected that the resulted knowledge and awareness can foster a sense of love for the environment and can also affect a better use of plastic.

    Abstract: Perubahan iklim memberikan dampak yang besar di berbagai negara. Adapun dampak dari terjadinya perubahan iklim adalah bertambahnya intensitas kejadian cuaca ekstrim di suatu wilayah, perubahan pola hujan, serta peningkatan suhu dan permukaan air laut Dampak perubahan iklim dapat memengaruhi keadaan di daratan maupun di pesisir atau laut. Salah satu wilayah di Provinsi Jawa Timur yang terkena dampak perubahan iklim yang mengkhawatirkan adalah wilayah Teluk Popoh yang terletak di Desa Besole, Kecamatan Besuki, Kabupaten Tulungagung, Provinsi Jawa Timur. Kerusakan yang terjadi di perairan pantai Sidem berupa perubahan garis pantai yang disebabkan oleh bertambah tingginya permukaan air laut serta adanya aliran sungai Neyama yang langsung bermuara di pantai Sidem, Teluk Popoh. Hal lain yang disebabkan oleh perubahan garis pantai di Teluk Popoh adalah rusaknya sumberdaya alam di perairan Teluk Popoh, dimana nelayan dan masyarakat pesisir Teluk Popoh akan semakin sulit untuk mencari ikan di perairan sekitar. Untuk menghindari terjadinya dampak perubahan iklim yang berkelanjutan, maka PLTA Tulungagung yang beroperasi di wilayah pantai Sidem Teluk Popoh dan pemerintah Kabupaten Tulungagung memberikan inisiatif berupa penanaman pohon dan mangrove di wilayah Pantai Teluk Popoh. Dengan upaya mitigasi tersebut diharapkan mengurangi dampak yang diberikan oleh perubahan iklim di Teluk Popoh. Mitigasi tersebut tidak akan berjalan tanpa adanya usaha adaptasi dari masyarakat sekitar Teluk Popoh. Masyarakat di Desa Besole merupakan masyarakat yang didominasi oleh para nelayan yang kehidupannya sangat bergantung pada keberadaan laut. Apabila terjadi perubahan iklim di laut, maka para nelayan dari Desa Besole perlu beradaptasi terhadap perubahaan iklim tersebut..

    Abstract: The condition of coral reefs in Damas Beach is included in the bad category because there are many fragments of coral reefs (rubble) caused by fishing nets caught in the reef. Based on the problem of coral reefs contained in the waters of Damas Beach, there are innovations to sink artificial reefs. The condition of artificial reefs that have been derived in the waters of Damas Beach within 2.5 years needs to be monitored to find out the macroinvertebrates that stick to the artificial reefs. Retrieval of macroinvertebrate data using the underwater photo transect method with the help of underwater cameras to produce observational data. The results found 10 types of macroinvertebrates with a total of 9,293 individuals. The composition of attached macroinvertebrates is dominated by barnacles by 66% and the density of macroinvertebrates is dominated by barnacles by 4.50 ind / m² out of a total density of 6.88 ind / m².

    Abstract: Ujungpangkah represents a deltaic region with one of the largest mangrove areas in East Java. This 1,554 Ha of high productivity mangrove area were designated as Essential Ecosystem Area (EEA) in 2020. However, linkage between mangrove conditions and fisheries activities within region have not been well documented. This study combines satellite remote sensing to analyze the temporal extent and distribution of mangrove vegetations, and field observation to identify local mangrove-fisheries characteristic. Area of study consists of mangrove and local fishing groups in Pangkahkulon and Pangkahwetan coastal villages. Both MVI and NDVI algorithms were performed on Landsat 8 and Sentinel-2 satellite imageries, using machine learning Google Earth Engine, to provide spatio-temporal change in mangrove extent during last decade (2011-2021). Field activities carried out in 8 sampling stations to analyze existing mangrove condition using Mangrove Health Index (MHI) tool, while semi-structured interview was conducted with representatives from 14 groups of fishermen from two coastal villages within EEA Ujungpangkah. Data obtained from this study include fish species, fishing gear, fishing ground locations, fisheries productivity, and fishery activities related to the mangrove in EEA Ujungpangkah. Correlation between mangrove conditions and fishery productivity in Ujungpangkah is expected to provide information about the local-based function of the mangrove ecosystem. This information may support stakeholders, particularly area managers, to implement sustainable management based on mangrove ecosystems in accordance with the SDGs -SDG2, SDG 13, and SDG 14.

    Abstract: Coral reefs in the southern waters of Malang Regency are characterized by wide reef flat areas which are generally dominated by massive, encrusting, and branching corals. The living and growth of Scleractinian coral have limiting factors: current velocity, salinity, temperature, DO, turbidity and pH. These factors have a very important role in influencing the rate of reproduction and recruitment of hard corals in the southern waters of the Malang Regency. The aim of this study was to determine the distribution of juvenile corals of Pulau Sempu and its surrounding waters. The study was conducted at five sites: Waru Waru, Teluk Semut, Tiga Warna, Kondang Merak, and Jembatan Panjang Tanjung Sirap (JPTS), from August to November 2020. The results showed that the distribution of juvenile corals had varying results at each research station. Eight families of hard juvenile corals are described in this study, including four families having the highest density: Acroporidae, Poritidae, Pocilloporidae, and Merulinidae. Based on statistics, it was found that the location had a positive impact on the number of juvenile coral densities (p = 8.3 x 10-35). This is the first research reporting on the distribution of juvenile corals, which will be very important for policymakers to determine the best rehabilitation method to protect coral reefs in the area.
