Abstract

This research aims to study the anatomical structure of macroalgae. Sample of macroalga was collected by using Line Intercept Transect (LIT) method with sampling quadrat. Macroalgae samples were dried and separated from the roots, stems, leaves and receptacles (if present). Samples were cut transversely and longitudinally at each section and observed under binoculared microscope of Olympus CX with monitor. Based on the histology, anatomical structure of macroalgae species can be divided into two tissues from outside to inside, namely cortex and medullary cells. The cortex is composed of one layer or more. The cortex is the area between the epidermis and the central column. The medulla cells only have one layer which is the largest layer. Based on the observation result of cells type from observed spesies Eucheuma denticilatum, Gracilaria arcuata, Hydropuntia edulis, G. salicornia, Hypnea valentiae, Turbinaria deccurens, and T. ornata, it shows that cells of medulla become small toward cortex.Indonesian title:  Karakteristik anatomi jenis makroalga dari Pulau Bombuyanoi, Kabupaten Bolaang Mongondow Timur, Sulawesi Utara

Abstract

Sharks are a group of cartilaginous fish that are vulnerable to overfishing.  Genetics approaches play an important role in shark conservation. Shark fishing has become the main activity of fishermen in several areas, including in North Sulawesi. This research is focused on the molecular aspects and conservation status of shark species obtained from the shark fin trade in Manado, North Sulawesi. COI gene was amplified using Fish BCL5 (for) and HCO219 (rev) primers. Nucleotide sequences of each sample were aligned with the closest sequences in the GenBank database using the BLAST (Basic Local Alignment and Search Tool) method. The conservation status of the shark species is carried through the IUCN (International Union for the conservation of nature red list) Red list website. Molecular identification results showed that the shark’s fins from Manado had high similarity with Carcharhinus falciformis (HM1 and HM2) and Carcharhinus melanopterus (HM3). According to IUCN red list data, the C. falciformis and C. melanopterus were categorized as vulnerable to extinction (VU).Keywords:  Molekuler; COI; Shark; Manado and IUCN Red list . AbstrakHiu merupakan kelompok ikan bertulang rawan yang sangat rentan terhadap dampak penangkapan secara berlebihan.  Informasi terkait genetik hiu  yang semakin terancam populasinya sangat berperan penting dalam upaya konservasi hiu.

Abstract

Taman Nasional Bunaken (TNB) is located in North Sulawesi Province, Republic of Indonesia. TNB offers an exploration experience of marine tourism such as snorkeling and diving. This study was conducted to determine the statistics and correlation of weather parameters on hydrodynamics in the waters of the small island of TNB. This information can be used by marine tourism users. The weather data studied are wind direction and speed. The hydrodynamic conditions studied were wave height and ocean currents. Respondent surveys were also conducted on tourist users at the research sites. The wind direction for the period January - April is dominant from the Northeast, May - September is dominant from the East to the South, October tends to be evenly distributed from the East to the West, and November - December is dominant from the West. Significant wind speeds that occur in January, February, and March range from 18 – 36 knots. The average wave height shows a significant value in January – March, tends to be lower in April – June, fluctuates in July – November, and increases again in December. The maximum current velocity at a sea depth of 16.5 m is stronger than the maximum speed at a depth of 0.5 m and 8.0 m in January – April, and May August. The correlation value of wind speed and sea wave height is significant at 0.96 and the correlation between wind speed and the current speed is 0.74. These results indicate that there is a strong -very strong relationship between parameters. The survey results show that wind speed, wave height, and ocean currents have the same pattern. January, February, November, and December are the months of extreme or bad weather and hydrodynamic conditions.Keywords: Taman Nasional Bunaken, Weather, Hydrodynamics, CorrelationAbstrakTaman Nasional Bunaken (TNB) terletak di Provinsi Sulawesi Utara, Negara Republik Indonesia.

Abstract

In the last few decades, coral reef ecosystem has been under significant pressure due to anthropogenic impacts and naturally driven factors. The coral reef ecosystem is unique because it has very high biodiversity and many organisms depend on its existence. Every organism in a coral reef ecosystem uniquely contributes to how coral reef communities survive and function. However, coral reef ecosystems are also vulnerable to pressures that cause degradation, interfering with the ecosystem balance. This study aims to monitor the ecological condition of coral reefs and the abundance of reef fish to see how the MPA program in Bahoi village helps the coral reef ecosystem from degradation. The data was collected using Line Intercept Transect (LIT) method, which was drawn 70 meters transect line horizontally at a depth of 3-5 meters. The same transect line was also used to collect data about reef fish by using a Visual Census. The observation distance length is 2.5 meters to the left and right of the transect line. Results of the study showed that the coral cover of MPA Bahoi Village is in the Fair category and the abundance of reef fish in the MPA area is in the Moderate category.  Keywords: Coral Cover; Coral Reef; Marine Protected Area (MPA); Monitoring; Reef Fish
