Ekosistem terumbu karang adalah ekosistem laut yang sangat rentan oleh kerusakan lingkungan. Terumbu karang di perairan Bilik, Taman Nasional Baluran merupakan contoh ekosistem terumbu karang yang mengalami ancaman kerusakan lingkungan akibat perubahan iklim dan aktivitas manusia. Salah satu metode yang dapat digunakan untuk memonitor kesehatan terumbu karang adalah dengan melihat kelimpahan megabentos dalam ekosistem terumbu karang. Oleh karena itu, penelitian ini memiliki tujuan untuk mengetahui kesehatan ekosistem terumbu karang dengan melihat kelimpahan megabentos di perairan Bilik, Taman Nasional Baluran. Metode yang digunakan dalam inventarisasi megabentos adalah dengan Benthos Belt Transect dan analisis video di Blok Sijile dan Blok Jeding di Perairan Bilik. Hasil pengamatan menunjukkan bahwa di Blok Sijile tidak ditemukan ekosistem terumbu karang dan megabentos. Sementara itu di Blok Jeding ditemukan ekosistem terumbu karang dengan megabentos berupa bulu babi dan bintang laut biru. Kelimpahan bulu babi di dan bintang laut biru adalah 0-0,14 individu/m2. Kondisi tersebut menunjukkan bahwa kesehatan ekosistem terumbu karang di Blok Jeding perairan Bilik Sijile masih baik, namun perlu mendapat perhatian khusus karena sebagian area terumbu karang mengalami pemutihan akibat aktivitas perikanan yang tidak ramah lingkungan.MEGABENTHOS ABUNDANCE AS CORAL HEALTH INDICATORS IN BILIK WATERS, BALURAN NATIONAL PARK, INDONESIA. Coral reef ecosystems are marine ecosystems that are prone to environmental damage. Coral reefs in Bilik waters, Baluran National Park, are examples of coral reef ecosystems that are threatened by environmental damage due to climate change and human activities. One of the methods for health monitoring of coral reefs is by looking at the abundance of megabenthos in coral reef ecosystems. Therefore, this study aims to determine the health of coral reef ecosystems by looking at the abundance of megabenthos in Bilik waters, Baluran National Park. We used Benthos Belt Transect and video analysis to identify the spatial distribution and number of megabenthos in Sijile Block and Jeding Block, Bilik waters. The results showed that in Sijile Block, there were no coral reef neither megabenthos ecosystems. Meanwhile, in Jeding Block, there was a coral reefs ecosystem with megabenthos in the form of sea urchins and blue starfish. The abundance of sea urchins and the blue sea star in Jeding Block was about 0-0.14 individual/m2. These conditions indicate that the health of the coral reef ecosystem in Jeding Block, Bilik waters was still in good condition, even though it still needs special attention related to coral bleaching as a consequence of fisheries activities that are not environmentally friendly.

Kondisi padang lamun di perairan Pantai Kema akan terus mengalami perubahan sebagai dampak negatif dari berbagai aktivitas penduduk setempat yang tidak konservatif. Akibatnya diversitas jenis ikan yang berasosiasi di dalamnya juga akan semakin berkurang. Akan tetapi, informasi mengenai diversitas spesies ikan padang lamun di daerah ini masih sangat terbatas. Oleh karena itu, pada bulan April 2014 dilakukan penelitian pada ikan padang lamun untuk mengetahui diversitas jenis dan kelimpahan ikan serta struktur komunitasnya. Pengambilan sampel dilakukan di empat stasiun dengan metode swept area menggunakan beach seine. Hasil tangkapan seluruhnya adalah 2.621 individu ikan, terdiri atas 60 spesies dari 26 famili. Jumlah spesies ikan yang ditemukan secara spasial bervariasi dari 27- 47 spesies dengan total kelimpahan relatif antara 14,08–34,91%. Famili Labridae dan Atherinidae merupakan famili paling dominan di semua stasiun dengan total kelimpahan relative sebesar 33,62% dan 25,45%. Tiga jenis yang paling umum ditemukan adalah Hypoatherina temminckii, Halichoeres papilionaceus dan Halichoeres melanurus. Komunitas ikan di padang lamun Pantai Kema termasuk kategori sedang (moderat) dengan stabilitas komunitasnya tidak stabil. Tipe asosiasi padang lamun yang berbeda mempengaruhi perbedaan keragaman jenis dan kelimpahan ikan yang hidup di dalamnya. Walaupun demikian, seluruh padang lamun di perairan pantai Kema masih dalam kondisi kondusif sebagai habitat ikan.Seagrass condition at Kema coastal area will continue to change as a negative impact of various activities of local people who are not conservative. As a result, the diversity of fish species is going to decrease. However, information about the diversity of seagrass fish species in this area is still limited. Therefore, in April 2014 a study of seagrass fish community structure was carried out to know the diversity of species, fish abundance and community structure. Sampling was carried out at four stations with swept area method using beach seine. A total of 2.621 individuals were collected, consisting of 60 species from 26 families. The number of fish species found spatially varies from 27 to 47 species with a total relative abundance of 14.08-34.91%. Labridae and Atherinidae families are the most dominant families in all stations with a total relative abundance of 33.62% and 25.45%. The three most common species are H. temminckii, H. papilionaceus and H. melanurus. Community structure of seagrass fish at Kema coastal area is moderate and unstable. The difference of seagrass beds association type affect the diversity of species and fish abundance. However, all seagrass beds at Kema coastal area are still conducive for fish habitat.

The purpose of this study was to determine the level of diversity and genetic relationship of Panulirus versicolor lobsters in Cenderawasih Bay and Lombok waters based on the cytochrome oxidase I (COI) gene. The results showed the level of genetic diversity of the two populations was very high and generally did not differ greatly between populations. We identified 6 haplotypes for P. versicolor lobster populations from Cenderawasih Bay and 7 haplotypes for P. versicolor lobster populations from Lombok waters. Network analysis shows that several P. versicolor lobster individuals from the Cendeawasih Bay and Lombok waters had similar haplotypes. The population of Cenderawasih Bay with Lombok waters was closely related to the average genetic distance value P-distance 0.005 (s.d 0.001) and the results of phylogenetic tree reconstruction showed that the two populations of P. versicolor lobsters form a monophyletic clade (close relatives).

Sebagai salah satu destinasi wisata bahari, pantai Gumumae menjadi lokasi liburan potensial bagi masyarakat Kota Bula dan sekitarnya. Memiliki luas 19.70 ha membantang dari Teluk Sesar sampai Sungai Wailola, turut berkontribusi pada pembentukan struktur dan karakteristik pantai. Dinamika fisik pesisir yang kompleks menjadi tujuan penelitian dilakukan. Harapannya pengelolaan Pantai Gumumae sebagai kawasan wisata bahari dapat dilakukan secara tepat dan berkelanjutan. Penelitian dilakukan pada bulan September sampai Oktober 2019, di Pantai Gumumae Kabupaten Seram Bagian Timur Provinsi Maluku. Pengamatan parameter fisik pesisir dilakukan secara insitu dan komparasi data penginderaan jauh, melalui satelit altimetri NASATOPEX/Poseidon, Jason-1/Envisat, dan Jason-2/Envisat tanggal 2 - 17 September 2019. Menggunakan analisis deskriptif kuantitatif, spasial dan temporal melalui citra satelit Landsat 8 dan arcgis imagery 2019, untuk mengetahui pengaruh dinamika fisik dalam bentuk peta tematik. Pantai Gumumae merupakan dataran rendah tetapi dikelilingi wilayah perbukitan disekitarnya. Pola curah hujan berfluktuasi dalam setahun, namun terdapat trend peningkatan sejak bulan September sampai November dan berdampak pada aliran sungai, tidak mengherankan transport sedimen yang dialirkan ke pesisir pantai Gumumae melalui muara sungai Wailola berada dalam jumlah yang besar. Termasuk kategori perairan dangkal dengan kedalaman 45 cm sampai 2.5 meter pada jarak >15 meter dari garis pantai ke arah laut. Tinggi gelombang relatif kecil yakni sebesar 0.68 meter – 0.82 meter, namun memiliki arus yang cenderung cepat di muara sungai Wailola. Anomali permukaan laut di pesisir Gumumae mengalami penurunan secara konstan sebesar 3mm sampai 116 mm. Kecepatan arus dan sudut elevasi perairan pantai mengalami fluktuasi sehingga memberi pengaruh pada arah dan kekuatan arus pantai, gelombang kecil, sedimentasi tinggi di muara hingga sebagian kawasan wisata. Perlu perencanaan yang komprehensif untuk pengelolaan wisata pantai Gumumae berdasarkan kesesuaian tata ruang. As one of the marine tourism destinations, Gumumae beach is a potential vacation area for the people of the city of Bula and its surroundings. It has an area of 19.70 ha stretching from the Sesar bay to the Wailola river, contributing to the formation of the structure and characteristics of the coastal. The complex physical dynamics of the coastal is the aim of the study. It is hoped that the management of Gumumae beach as a marine tourism area can be carried out appropriately and sustainably. The study was conducted from September to October 2019, on the coastal of Gumumae, East Seram Regency, Maluku Province. Observation of coastal physical parameters was carried out insitu and compared remote sensing data, via satellite altimetry NASATOPEX / Poseidon, Jason-1 / Envisat, and Jason-2 / Envisat on 2-17 September 2019. Using quantitative descriptive analysis, spatial and temporal through satellite imagery. Landsat 8 and Arcgis Imagery 2019, to determine the effect of the physical dynamics of the Gumumae coastline in the form of thematic maps. Gumumae Beach is a low-lying area but is surrounded by hilly areas around it. Rainfall patterns fluctuate within a year, but there is a trand increase from September to November and have an impact on river flow, it is not surprising that sediment transport flowed to the coastal of Gumumae via the Wailola river mouth is in large numbers. Current velocity and elevation angle of coastal waters fluctuate so that it influences the direction and strength of coastal currents. Included in the category of shallow water with a depth of 45 cm to 2.5 meters at a distance of> 15 meters from the coastline towards the sea. The wave height is relatively small at 0.68 meters - 0.82 meters, but has a current that tends to be fast at the mouth of the Wailola river. Sea level anomalies on the coastal of Gumumae are constantly decreasing by 3mm to 116 mm. Need a comprehensive planning for the management of Gumumae beach tourism based on spatial suitability. As one of the marine tourism destinations, Gumumae beach is a potential vacation area for the people of the city of Bula and its surroundings.

Observation of coastal physical parameters was carried out insitu and compared remote sensing data, via satellite altimetry NASATOPEX / Poseidon, Jason-1 / Envisat, and Jason-2 / Envisat on 2-17 September 2019. Using quantitative descriptive analysis, spatial and temporal through satellite imagery. Landsat 8 and Arcgis Imagery 2019, to determine the effect of the physical dynamics of the Gumumae coastline in the form of thematic maps. Gumumae Beach is a low-lying area but is surrounded by hilly areas around it. Rainfall patterns fluctuate within a year, but there is a trand increase from September to November and have an impact on river flow, it is not surprising that sediment transport flowed to the coastal of Gumumae via the Wailola river mouth is in large numbers. Current velocity and elevation angle of coastal waters fluctuate so that it influences the direction and strength of coastal currents. Included in the category of shallow water with a depth of 45 cm to 2.5 meters at a distance of> 15 meters from the coastline towards the sea. The wave height is relatively small at 0.68 meters - 0.82 meters, but has a current that tends to be fast at the mouth of the Wailola river. Sea level anomalies on the coastal of Gumumae are constantly decreasing by 3mm to 116 mm. Need a comprehensive planning for the management of Gumumae beach tourism based on spatial suitability.
