The Indonesian government plans to move the capital city from Jakarta to Penajam Paser Utara (PPU) which is the upstream area of Balikpapan Bay, East Kalimantan. There are several activities in the planned new capital city that potentially affect the condition of land and marine ecosystems, including clearing new land for housing and agriculture as well as expanding mining and petroleum areas. Directly or indirectly, these activities could affect the oceanographic conditions of Balikpapan Bay. For this reason, in order to obtain an up-to-date picture of Balikpapan Bay, an oceanographic survey was conducted in early March 2020. In addition, to support the analysis of marine dynamics in these waters and their predictions in the future, numerical simulations of hydrodynamic modeling were also carried out. Oceanographic observations indicate significant water stratification in the area about 20 km from the mouth of the bay. This result is also well illustrated in the hydrodynamic model numerical simulation, where there is a water loop at the confluence between salt and fresh water masses from two rivers 18-20 km from the mouth of Balikpapan Bay.

Abstract. Karang Makassar is known as Manta point which is located in the Komodo National Park, Indonesia. This location is one of the habitat for manta ray. This research was conducted to find out the relationship between the appereance of manta ray with lunar pattern and tidal cycle. Observation data was collected from September to October 2012. Photo ID method was used to assess the number of manta ray appeareance. Lunar pattern data was obtained from USNO NAVY database, and tidal cycle was obtained from WX Tide Prediction Server. The result shows that from 20 dives, the highest average number of manta rays appearance was during full moon by 9,8 individual per dive. Meanwhile, during half moon and new moon were only 3 individual appearances per dive. On the other hand, based on tidal cycle, the highest manta rays appeareance was found during rising by 6,5 individual per dive, on falling by 4,4 individual per dive, and the lowest on slack by 3,4 individual per dive. We suggest that the best time for seeing manta rays in this location is during full moon and raising time. Keywords: Manta rays; Lunar patterns; Tidal cycle; National Komodo Park Abstrak. Perairan Karang Makassar, dikenal sebagai Manta Point yang berada di Taman Nasional (T.N.) Komodo, Indonesia. Lokasi ini merupakan salah satu habitat bagi pari manta. Penelitian kali ini dilakukan untuk mengetahui hubungan antara kemunculan pari manta dengan fase bulan dan pasang surut. Pengambilan data dilakukan pada bulan September – Oktober 2012. Metode Photo ID dipergunakan untuk menhitung jumlah individu kemunculan pari manta. Sedangkan untuk data fase bulan diperoleh dari USNO NAVY berupa persentasi cahaya bulan, sedangkan untuk pasang surut didapatkan dari WX Tide Prediction Server. Hasil menunjukkan bahwa dari 20 kali penyelaman, rata-rata kemunculan tertinggi terjadi saat fase bulan penuh sebesar 9,8 individu per penyelaman. Pada bulan setengah jumlah kemunculan paling sedikit yaitu 3 kemunculan per penyelaman, sama dengan fase bulan baru yaitu 3 kemunculan per penyelaman. Sementara itu berdasarkan pola pasang surut, diperoleh rata-rata jumlah individu tertinggi yang muncul yaitu pada pada saat pasang sebanyak 6,5 individu per penyelaman, saat surut sebesar 4,4 individu per penyelaman, sedangkan pada saat kendur paling sedikit yaitu sebesar 3,4 individu per penyelaman. Kami menyarankan bahwa waktu yang terbaik untuk melihat pari manta di lokasi ini adalah pada saat bulan penuh dan saat pasang.Kata kunci: Pari Manta; Fase Bulan; Pasang Surut; Taman Nasional Komodo

Abstract. Kawan fish (Poropuntius tawarensis) is an endemic fish found in Danau Laut Tawar, Central Aceh, Indonesia. This species has been threatened by ecological partubation, unfrindly fishing practices and pollution. Cryopreservation is one of the ways to maintain the presence of these fish. Cryoprotectant (CP) is a critical material in the cryopreservation and DMSO is a common CP used in cryopreservation. Hence, the aim of the present study was to determine the optimum DMSO concentration for kawan fish sperm. The completely randomized design with 6 treatments and 3 replications were used in this study. The tested treatment was the difference of DMSO concentration, namely; 0, 3%, 6%, 9%; 12%, and 15% DMSO was combined with 5% egg yolk. The ratio of sperm to diluent is 1: 20. The cryotubes containing diluented sperm were evaporated at 5 cm from the surface of liquid nitrogen for 10 min, then stored in a liquid nitrogen container at -1960C for 2 weeks, then thawed and analyzed for the quality. The results showed that fresh sperm of kawan fish had motility of 48.67%, pH 7, milky white, with moderate consistency. The assessment of mass movements shows that the sperm has good quality. The ANOVA test showed that the addition of DMSO in diluents gavee significant effect on sperm motility, fertility and hatchability rates of fish eggs (P 0.05). The highest percentage of sperm motility and fertilization rates of fish eggs were found at concentration of 6%, respectively with the value of 46.67% and 45.67%, respectively. The highest percentage of hatching rate was also found in similar concentration of DMSO with the value of 19.33%. %. The DNA integrity test using the electrophoresis gel method showed that there was damage to DNA fish sperm after freezing, the the lower damage was found at 9% and 12% DMSO. It is concluded that the optimum concentration of DMSO for kawan fish sperm is at 6% of DMSO. Key words: kawan fish (Poropuntius tawarensis), cryopreservation, DMSO, DNA integrity Abstrak. Ikan kawan (Poropuntius tawarensis) merupakan ikan endemik yang terdapat di Danau Laut Tawar, Aceh Tengah, Indonesia. Menurut IUCN (International Union for Conservation of Nature), ikan ini termasuk ikan yang terancam punah oleh sebab kerusakan lingkungan, penangkapan tidak ramah lingkungan dan polusi. Salah satu cara untuk menjaga keberadaan ikan tersebut adalah dengan penerapan metode kriopreservasi sperma. Oleh karena itu, penelitian ini bertujuan untuk menentukan konsentrasi DMSO optimum dan melihat kerusakan DNA yang terjadi pada sperma ikan kawan(Poropontius tawarensis) pasca pembekuan.Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 6 perlakuan dan 3 ulangan.Perlakuan yang diuji adalah perbedaan konsentrasi DMSO dengan konsentrasi 0; 3%; 6%; 9%; 12% dan 15%.DMSO tersebut dikombinasikan dengan 5% kuning telur. Perbandingan sperma dengan pengencer adalah 1 : 20. Semua cryotube yang berisi sperma dan pengencer diuapkan pada jarak 5 cm dari permukaan nitrogen cair selama 10 menit, selanjutnya, disimpan dalam kontainer nitrogen cair bersuhu -1960C untuk disimpan selama 2 minggu. Hasil penelitian menunjukkan bahwa sperma segar ikan kawan memiliki nilai motilitas sebesar 48,67%, pH 7, berwarna putih susu, dengan konsistensi sedang. Penilaian gerakan massa menujukkan bahwa sperma tersebut berkualitas baik. Hasil uji ANOVA menunjukkan bahwa penambahan DMSO dalam pengencer berpengaruh nyata terhadap motilitas, fertilitas dan daya tetas telur ikan kawan (Poropontius tawarensis) (P0,05) setelah pembekuan. Selanjutnya, uji lanjut Duncan menunjukkan bahwa persentase motilitas sperma dan pembuahan telur ikan kawan tertinggi terdapat pada penambahan DMSO dengan konsentrasi 6%, masing-masing sebesar 46,67% dan 45,67%. Persentase penetasan telur tertinggi juga dijumpai pada perlakuan 6% DMSO, dengan nilai 19,33%. Hasil uji integritas DNA menggunakan metode elektrofresis gel menunjukkan bahwa terdapat kerusakan pada DNA sperma ikan pasca pembekuan, Kerusakan yang terendah terdapat pada konsentrasi DMSO 9% dan 12%. Namun secara umum, disimpulkan bahwa konsentrasi optimum untuk kriopreservasi ikan kawan adalah 6% DMSO.Kata kunci: ikan kawan (Poropuntius tawarensis), kriopreservasi, DMSO, integritas DNA

Sembilan Island was one of the 17 islands located in the East Coast of North Sumatra. This island is surrounded by mangrove with varying thickness and density. Information on the identification and potential of mangrove in this island already reported but limited to a narrow area. Information about the value and status of mangrove ecology in this island have not been written, so it was needed to carry out for a study of mangrove ecological analysis. This information could be used later as a reference in sustainable mangrove management. The objective of the study was to determine the value and ecological status of mangroves. The research was conducted in September 2015. The data were collected at 9 sampling points namely; 4 points in the east, 2 points in the south and 3 points in the west part of the study areas. The spot check method was used in the study. The results showed that there were 28 species of mangrove belonging to 13 families. It's divided into 26 species of true mangrove and two species of associated mangroves. Mangrove’s zonation was Avicennia/Sonneratia on the front and ferns (A. Aureum and A. speciosum) in the section near the mainland. Mangrove thickness reached 134 - 1683 m. The density of mangrove was 333 - 4601 individuals/ha with the cover area of 2522 - 5810 cm2/ha. The results of the importance index value of mangrove showed that A. marina has a great influence and role in the community of mangrove vegetation, especially in the eastern part. Therefore, the mangrove in Sembilan Island was categorized into damage to good condition. The good category was recorded in the western part of the island, while the damaged category was found in the east part of the island.Pulau Sembilan merupakan satu diantara 17 pulau yang terdapat di wilayah Pantai Timur Sumatera Utara.

Data on bycatch in the fishing effort required to manage fisheries resources. Unfortunately, the data on small-scale and traditional fisheries is still lacking. It makes it challenging to make fishing policies and regulations. Survey activities and experimental fishing were conducted to determine and analyze the composition of the main catch, bycatch and discarded by the local fisher's bottom traps in Sibolga, North Sumatra, Indonesia. Five units of the trap with a size of 150 cm x 100 cm x 50 cm (length x width x height) were used to collect fish data. These five trap units operated in the fishing ground, where local fishers usually operate their fishing gear. The fishing operation carried out within 1 mile of the coastline with water depths ranging from 7-10 meters. The duration of trap setting around 5-7 days for each fishing operation. A motorboat operated with a weight of 5.8 GT. The results showed that the total bottom trap catch consisted of 329 individuals with a total weight of 151.4 kg and 12 demersal fish species. The main catch was 148 individuals (88.9 kg), or 44.7% of the total catch during the experiment i.e. Chepalapholis urodeta, Ephinephelus areolatus, Epinephelus chlorostigma, Plectropomus leopardus, Ephinepelus coioides, Lates calcarifer, Lutjanus malabaricus, and Lutjanus erytropterus. The bycatch was 151 individuals (57.1 kg) or 46.1% i.e. Lethrinus obsoletus, Lutjanus ehrenbergii, Acanthurus auranticavus, Platax teira, Nemipterus japonicus, Scarus rivulatus, Lutjanus johnii, Siganus canaliculatus, Caesio cuning, and Taeniura lymma.While the discarded catch amounted to 30 individuals (5.4 kg) or 9.2% i.e. Naso brevirostris, Diodon holocanthus, and Diadema setosum. The bycatch utilization obtained by fishers was 83.4%, and the unutilized was 16.6%. The percentage of fish sizes worthy for consumption was 135 individuals (74.6%), and the size unworthy for consumption was 46 individuals (25.4%).Keywords:Fishing groundFishing gear Fishing operation Main catchTrap
