Abstract

Penelitian yang dilakukan untuk mengetahui pengaruh cahaya terhadap pertumbuhan karang lunak Lobophytum strictum hasil transplantasi dilakukan dengan pemeliharaan karang lunak pada dua buah kolam, yaitu kolam terbuka (cahaya) dan kolam tertutup (tanpa cahaya). Pada masing-masing kolam ditempatkan 16 fragmen karang lunak yang sudah ditransplantasikan. Kelangsungan hidup dan pertumbuhan karang lunak berbeda signifikan antar perlakuan cahaya (P<0,05). Karang lunak yang dipelihara di kolam terbuka mampu bertahan hidup 100% (12 minggu), dengan disertai peningkatan panjang (5,95-10,04 cm)  dan lebar (5,27-6,84 cm) fragmen karang. Hal yang berbeda ditunjukkan karang lunak yang dipelihara di kolam tertutup, hanya mampu bertahan hidup hingga minggu ke-8 (62,5%). Hal ini disertai dengan penurunan panjang (8,25-5,25 cm) dan lebar (9,14-4,86 cm) fragmen setiap minggunya.

Abstract

Grouper fish is the most exploited commodity for coral fisheries. The controversy that occurred between researchers regarding the identification of fish species is a problem that is quite alarming. Identification using morphometric measurements, shape and color or morphology is considered still not accurate in determining the fish species. The DNA barcoding method uses COI markers by tracing the nucleotide bases to determine which species of biota have advantages in species identification. This study aims to identify grouper fish species in the traditional Muara angke fish market by using morphological methods and DNA barcoding. The identification results obtained from the morphological methods (shape, color and morphometrics) that the sample species are white-tailed grouper fish (Epinephelus areolatus) by looking at morphological characteristics, namely the white lines on the caudal fins and brown spots on the body. Identification using the DNA Barcoding method using the COI markers showed that the fish samples were 95% similar to E. areolatus.

Abstract

The area of mangrove Segara Anakan has a high economic value so that there is a high interest to various land uses in this area. This condition leads to the change in ecological function of the mangrove which has impacts on the decreased production of mangrove crabs. This study was desighed to analyze the areas of catching crabs related to mangrove ecosystem. This study was conducted for six months in the 3 mudcrab catching areas (Western Area, Central Area, and Eastern Area). The analysis used in this study was a one way ANOVA statistic for the crabs catching in these 3 catching areas, and a simple linear regression to analyxe the correlation betwen annual crab production and mangrove area. The results showsed that mud crabs catchings in the 3 areas is 5861.7; 6072.87; dan 7689.4 kg were significantly different (P<0.05) and the linear regression between the area of mangrove in Segara Anakan and crab?s production of the Cilacap Regency was Y= 14.951X-88357 with R2 = 0.54. These results described that the number of crabs catching was influenced by the condition of mangrove in the 3 catching areas while the regressionb analysis showed that the decreased mud crab?s production in Cilacap Regency was correlated to the decrease in the area of mangrove Segara Anakan.

Abstract

Local ecological knowledge (LEK) refers to the knowledge of people in a local community that can be used in assessing environmental conditions as well as reflecting the interaction that occur in an ecosystem. The purpose of this study was to examine condition of coral reef ecosystem based on the LEK?s community in a marine protected area east coast weh island (KKPD PTPW) Sabang. Assessment of the coral reef condition based on the local?s ecological knowledge is justified from the suitability of the area by comparing map of the coral reefs condition based on LEK and observation map of the coral reefs condition during the study. Based on LEK, it is known that in the PTPW Sabang region coral reefs which falls under deteriorated class is found in the northern sea of Kelurahan Kota Atas, while those which falls under good condition class are found in Ie Meule and Ujung Kareng as well as in Anoi Itam except Benteng. Result from the observations done in 13 stations found that sea region near Sumur Tiga, Ujung Kareung and Benteng have a good coral reefs with a coverage range of 51-65 %. While the sea in Ujung Seuke, Anoi Itam and Reuteuk have a moderate coral reefs with a percentage of coverage ranging from 44- 49. Respondents? perceptions of the coral reef condition during the last 10 years which include 55% respondents in Ie Meule and 74.29% of respondend in Anoi Itam stated that there is an increment of coral reefs coverage.

Abstract

The genetic connectivity of soft coral is influenced by current and distance between islands. The complexity of islands and geographical region in Indonesia might influence the distribution of soft corals.  The information of genetic connectivity can be used to design marine protected areas and to avoid destruction and possible extinction. The objective of the present study was to analyze genetic connectivity of one species of soft coral, Sarcophyton trocheliophorum, in three populations spanning Java, Nusa Tenggara, and Sulawesi’s waters, and to describe its implication for marine protected area. The mitochondrial protein-coding gene (750 bp of ND2) was used to analyze genetic population structure and genetic connectivity. Genetic connectivity was found in all populations with Fst value of 0.227 to 0.558, indicating populations had the close genetic relationship. The local and Indonesian currents were expected to distribute the larva to islands as a stepping stone, they moved slowly to spread them self far away. Tanakeke island (Sulawesi population) might be a center connectivity of S. trocheliophorum populations. This island connected with islands in west and east Indonesia, therefore that area need to protect

Abstract

Seagrass ecosystems are inhabited by many species of benthic invertebrates, demersal and pelagic organisms that reside or stay temporarily in seagrass ecosystems. This research aimed to analyze the density of the macrozoobenthos in two different moon phases and to seek the contribution of each macrozoobenthic species in each research stations at seagrass beds. Sampling of the macrozonthic organisms was taken in three research stations of Panggang Island (west, east, and south) by using a 1 x 1 m of quadratic transect and a sediment corer with 10 cm in diameter. The data analysis statistically analysis data was carried out by finding out the similarity percentage of the species contribution using SIMPER test. Results of this research indicate that the discovered macrozoobenthos for two phases of moon are varied in each station. The total found macrozoobenthos during two moon phases are 28 and 11 species in the west station, 24 and 20 species in the east station, and 18 and 24 species in the south station, respectively. In the three stations, the two highest and the lowest species density of macrozoobenthos during the two moon phases namely are Cerithium salebrosum (283 ind/m2) and Cerithium punctatum (169 ind/m2); and Geotrochus multicarinatum (7 ind/m2). Moreover, the most contributor species of macrozobenthos in the seagrass habitat of the entire stations is Cerithium salebrosum.

Abstract

Kelangkaan data spasial kelautan merupakan permasalahan mendasar dalam perencanaan pembangunan kelautan di negara berkembang seperti lndonesia. Untuk mengatasi permasalahan ini, teknologi inderaja menjadi salah-satu alternatif pilihan. Salah satu ekosistem laut yang mengandung kekayaan sumberdaya alam adalah ekosistem terumbu karang. Pemanfaatan data inderaja untuk pemetaan ekosistem terumbu karang telah diperkenalkan di lndonesia sejak tahun 90-an dan saat ini sudah umum digunakan di Indonesia. Namun demikian, data inderaja mempunyai keterbatasan untuk memetakan objek terumbu karang karena berada hingga kedalaman tertentu yang tidak ada penetrasi cahaya. Pola distribusi terumbu karang yang mengikuti geomorfologi dasar perairan sangat mempengaruhi hasil penginderaan. Hasil penelitian di kepulauan Una-una Togean menuniukkan bahwa interpretasi dari citra satelit tidak menggambarkan kondisi terumbu karang yang sesungguhnya.Kata Kunci: Data Spasial, Kelautan, Inderaja, Terumbu Karang ABSTRACTThe lack of marine spatial data is the fundamental problems in marine development planning in developing countries like Indonesia. We need remote sensing technology to be one alternative option to get over this problem. A coral reef ecosystem is one of the marine ecosystems that contain a rich of marine resources. Utilization of remote sensing data for napping coral reef ecosystems have been introduced in Indonesia since the 90’s and now is commonly used in Indonesia. However, the remote sensing data has limitations for coral reef napping object being in a certain depth into which has no light penetration. Distribution patterns of coral reef following the bottom geomorphology of water influence the sensory results. The results of research conducted in the Una-una Togean Island showed that the coral reef map derived satellite images did not describe the real condition of the reef.

Abstract

Genetik menjadi kunci konservasi karena berperan penting dalam  mempertahankan dan memulihkan populasi dari kerusakan. Kerusakan pada ekosistem terumbu karang dapat menjadi pemicu kepunahan organisme laut. Salah satu organisme yang tidak terhindar dari kerusakan tersebut ialah Sarcophyton trocheliophorum. Kerusakan tersebut dapat menyebabkan menurunnya keragaman genetik S. trocheliophorum. Tujuan dari penelitian ini adalah menganalisis keanekaragaman genetik dari S. trocheliophorum yang terdapat pada tiga populasi di Perairan Jawa, Sulawesi dan Nusa Tenggara serta mendeskripsikan implikasinya terhadap kawasan konservasi  di Indonesia. Penelitian ini menggunakan penanda genetik ND2 untuk menganalisis struktur populasi, konektivitas, dan keragaman genetik. Keragaman genetik S. trocheliophorum pada Perairan Jawa, Sulawesi, Nusa Tenggara masing-masing 0.600, 0.815, dan 0.972. Keragaman genetik pada populasi Perairan Jawa lebih kecil dibandingkan pada Populasi Perairan Sulawesi dan Nusa Tenggara. Hal ini dimungkinkan karena banyaknya aktivitas manusia pada pesisir utara Laut Jawa, sehingga berdampak pada menurunnya ukuran populasi S. trocheliophorum. Oleh karena itu perlu adanya perlindungan yang ketat pada populasi Jawa untuk menjaga kelestarian keanekaragaman hayati Indonesia.

ABSTRAKKeberadaan ekosistem lamun di perairan pesisir pulau-pulau kecil berperan penting sebagai habitat dan penyedia sumber daya ikan, serta pelindung garis pantai dan daratan pulau-pulau kecil tersebut. Penelitian ini bertujuan untuk menganalisis sebaran, komposisi, kerapatan, penutupan dan asosiasi jenis lamun di perairan pulau-pulau kecil Hiri, Ternate, Maitara dan Tidore, Maluku Utara. Pengambilan data dengan menggunakan metode transek garis dan transek kuadrat. Selanjutnya data dianalisis dengan menggunakan bantuan perangkat lunak MS Excel dan XLstat. Hasil penelitian menunjukkan bahwa Pulau Tidore memiliki jumlah jenis lamun terbanyak yakni delapan jenis lamun dari sembilan jenis lamun yang ditemukan di seluruh lokasi penelitian. Tiga jenis lamun yaitu, Enhalus acoroides, Thalassia hemprichii dan Cymodocea rotundata, menyebar luas dan terdapat di keempat pulau tersebut. Komposisi, kerapatan dan penutupan jenis lamun bervariasi antar stasiun penelitian. Vegetasi lamun yang ditemukan di lokasi penelitian berupa vegetasi campuran yang terdiri dari tiga sampai delapan jenis lamun. E. acoroides banyak ditemukan di Stasiun Mtr1 dan Tte2 tidak berasosiasi dengan spesies lainnya, demikian juga dengan C. serrulata yang ditemukan di Stasiun Mtr2 dan T. hemprichii di Stasiun Tdr2 dan Tdr3. Asosiasi C. rotundata dan Syiringodium isoetifolium terlihat di stasiun Tdr1 dan Hr1, sementara Halophila ovalis dan H. spinulosa  tidak menunjukkan asosiasi dengan jenis lamun lainnya di lokasi penelitian. Secara keseluruhan kondisi lingkungan perairan di keempat pulau tersebut masih tergolong baik dan mampu mendukung ekosistem lamun. ABSTRACTThe existence of seagrass ecosystems in the coastal region of small islands has been playing an essential role as a habitat and the supplier of fish resources, as well as a shore and coastline protector of small islands. This study aimed to  determine the distribution, composition, density, coverage, and associations of seagrass plant in the islands of Hiri, Ternate, Maitara, and Tidore. Data were collected by using line transect method and quadrate transect. Furthermore, data were analyzed by using MS Excel and XLstat software. The results showed that Tidore Island has the highest number of seagrass species namely eight from nine species of seagrasses found in all research sites. Three species of seagrasses, Enhalus acoroides, Thalassia hemprichii, and Cymodocea rotundata, were widespread in all four islands. The composition, density and coverage of seagrass species varied among research stations. Vegetation of seagrasses found in the study site in the form of mixed vegetation consisting of three to eight species. Enhalus acoroides found mostly in Mtr1 and Tte2 stations were not associated with other seagrass species, nor Cymodocea serrulata that found in Mtr2 Station and T. hemprichii at Tdr2 and Tdr3 stations. The associations of C. rotundata and Syringodium isoetifolium were observed at Tdr1 and Hr1 Stations. While Halophila ovalis and Halophila spinulosa showed no association with other seagrass species at the study area. Overall the condition of the marine environment on the four islands is still relatively good and able to support the life of the seagrass ecosystem.
