Abstract

The current research was conducted to investigate the effect of light on growth of soft coral Lobophytum strictum. This species was transplanted and reared in two different ponds, uncovered pond (with light penetration) and covered pond (no light penetration. A total of 16 coral fragments was placed on each pond. Both, the survival rate and the growth rate were significantly different on the effect of light (P<0.05). The soft coral on the uncovered pond was survive up to 12 weeks (100%), followed with increased length (from 5,95 to 10,04 cm) and width (from 5,27 to 6,84 cm) of the transplanted coral fragments. Conversely, the soft coral in the covered ponds showed survival rate of 62,5% (up to 8th week), with decreased length (from 8,25 to 5,25 cm) and width (from 9,14 to 4,86 cm) of each fragments during the period of study.

Abstract. Research on the sponge barnacle of Indonesia is very rare, and this study is aimed to describe the morphological characteristics of sponge barnacles and their specific relationship with their sponge host species. This research was a survey and sponge samples were collected by tearing apart any available sponge found in three sampling locations, typically coral reef areas of Weh Island, Seribu Islands, and Karimunjawa Islands. Sponge barnacles contained in sponge samples were observed using stereo microscope and scanning electron microscope, and species identification was determined based on the morphological description of Darwin (1854), Pilsbry (1916), Martin dan Davis (2001), and Kolbasov (1993). Four species of sponge barnacles were found consisting of Acasta cyathus, Acasta fenestrata, Euacasta dofleini, and Membranobalanus longirostrum. Specific relationships of barnacle and its sponge host were found between Euacasta dofleini and Haliclona sp. and between Membranobalanus longirostrum and Suberites sp. respectively.

Abstract

Coral reef ecosystem management in Siantan Tengah District, Anambas Islands need to be improved to obtain the optimal results. Currently, the coral reef ecosystem management is conducted sectorally, therefore, it can cause a damage on coral reef ecosystem. The purposes of this study were to analyze sustainability status of coral reefs managements in the District Central Siantan and to  formulate the sustainability of coral reef ecosystem management. Multi Dimensional Scaling (MDS) with Rap-Insus COREMAG approach was used to analyze the sustainability status of coral reef management. The results showed that the sustainability status of coral reef management in Siantan Tengah District was sustainable with multidimensional index of 51.457. Dimensions that need to be improved to achieve the optimal management of coral reef ecosystems in a sustainable manner is social dimension to the value of sustainability by 42.324 and institutional dimensions of 49.85 which is classed as less sustainable. This results of this research are expected to be able to facilitate the stakeholders to arrange the sustainability of coral reef ecosystem management in the Siantan Tengah District.

Abstract

Reliable and precise species identification is important to fisheries management and conservation. However, many rays and skates in Indonesia are currently being exploited and landed into traditional fish market without a proper identification. Therefore, this study was conducted to identify species of skates and stingrays that were landed and traded in three fish markets in Indonesia (Palabuhanratu, Muara Saban, and Lampung) using molecular techniques and to determine the conservation status of the identified species based on IUCN (International Union for Conservation of Nature and Natural Resources) as well as defined by CITES (Convention on International Trade in Endangered Species). The mitochondrial cytochrome oxidase I (COI) gene was amplified by polymerase chain reaction (PCR) using a pair of primer, fish-BCL and fish-BCH. Of 29 tissue samples collected from the study sites, a total of five species were successfully identified: Dipturus chilensis (4), Himantura walga (1), Neotrygon kuhlii (11), Taeniura lymma (9) and Rhinoptera javanica (4). The Neighbor Joining phylogeny of mitochondrial lineages, based on partial COI gene sequences, the ingroup haplotypes were clustered into five main clades representing each species. The identified stingrays were being listed as vulnerable (D. chilensis and R. javanica), near threatened (H. walga and T. lymma), and data deficient (N. kuhlii) by IUCN, with two species (D. chilensis and H. walga) population were indicated decreased. Unfortunately, all of identified species have not been evaluated by CITES regarding their trade status. As a consequences, a valuable effort should be placed to create a scientific network for monitoring programmes not only on a local scale, and to make pressure on governments for adopting molecular techniques as tools for controlling and avoiding misidentification.

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

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.

Abstract

Coral reef now are under threats due to sedimentation. Fatal effect of organic rich sediment, leading corals mortality. Therefore, the study was conducted to investigate effect of organic sediment content to the coral diversity in Karimunjawa Island, Central Java, Indonesia. Field data was conducted at 6 locations.  Three sediment traps were deployed at each sites to measure organic sediment content. Twenty replicated quadrant transects were used to estimate coral density and coral diversity. Analysis of variance (ANOVA) was used to examine the differences of organic sediment content in each station. The linear regression was used to assess the relationship between organic sediment content and coral diversity. Our field result demonstrated that sediment content significantly different between sites with value range from 0.42 mg/800 ml - 1.32 mg/800 ml. Based on the Simson’s Diversity Index, the highest coral diversity found at Alang-alang as site with low sedimentation while the lowest coral diversity was found at Legon Lele as site with high sedimentation. The study shown significant negative correlation between organic sediment content and coral diversity with the coefficient of regression 0.68. This study convinces that disturbance on coral reefs might affect coral diversity in Karimunjawa Island, in addition to other factors such as the influence of human activities, natural disruption and climate change. Keywords: sedimentation, organic, coral, diversity, Karimunjawa

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

 Metabolite profiles and antioxidant activity of Caulerpa racemosa extract with different handlings were investigated. Three different handlings during transportation were applied, namely samples chilled with ice, stored in liquid nitrogen and soaked in seawater. The different handling significantly affected the yield of ethanolic crude extracts and inorganic fractions but insignificantly to organic fractions. Different handlings resulted in differences of major fractions of C. racemosa extracts. Major fractions of the sample that was handled with chilling temperature contained low polar fractions (K10, K11, K12, and K13), while seawater handling extract contained very polar (K1, K2 and K3), polar (K6, K7, and K8) and low polar (K13) fractions. The extract of the sample handled in liquid nitrogen contained balanced fractions. Chilling temperature handling produced highest antioxidant activity (IC50 below 2,000 ppm) in ethanolic extract of C. racemosa.
