Abstract

Sea grass bed is an important ecosystem in coastal areas and small islands which plays important and effective roles as a protector of the coastal line and the safety of the mainland area of small islands. Physically, the roles of ecosystem were as erosion prevention, sediment trap and barrier of waves and currents. The existence of these ecosystems in the coastal regions and small islands was an important in enhancing the adaptive capacity of islands against natural disaster because the island serves as a natural protector. The aim of this research was to calculate and assess tha adaptive capacity of sea grass ecosystems growing in the waters of around the small islands in the group of Guraici. The research was conducted on 17 islands located in the group of Guraici islands. Measurement of adaptive capacity of sea grass ecosystem was done by analyzing 6 parameters, namely: Sea Grass Dimension Index (IDLn), Dominant Species of Sea Grass, Sea Grass Coverage Percentage (%), Number of Sea Grass Species, Substrate Type, Distance from The Point of Ecosystem. Sea Grass ecosystem adaptive capacity value was in the range between 0.0-1.0, with capacity of five categories of “very low, low, medium, high and very high”. These results indicated that sea grass ecosystem growing in the waters of around the islands in the island of group Guraici had adaptive capacity with values ranging between 0.0-0.59. The ranges of values were distributed into three categories of the adaptive capacities (very low, low and medium). A total of 13 islands had a capacity of sea grass ecosystem “medium”, the other three islands with capacity of “low” and one island with a capacity of “very low”.    Key words : Adaptive Capacity, seagrass ecosystem.

Abstract

Chlorophyll-a is a phytoplankton pigment involved in photosynthesis. Chlorophyll-a concentration detection through satellite orbiting can only be infered the concentration of chlorophyll-a at sea surface and could not estimate the sea primary productivity. Sea Primary productivity may last up to a depth of compensation or the depth at which the intensity of light stayed at least 1% of sea surface light intensity. However, the aim of this study is tofind out the relationships between the concentration of chlorophyll-a and primary productivity so that the concentration of chlorophyll-a could be used to predict primary productivity. The linear regression equation have been applied to construct model explaing relationship between the chlorophyll-a concentration and sea primary productivity. The equation explaing on chlorophyll-a concentrations with primary productivity is PP = 22.746 + 95.536Keu (R²) = 0.66 where PP is the sea primary productivity, Keu is the average of chlorophyll-a concentration throughout the water column. The results of these equations can be applied to satellite imagery so that it can assist in monitoring water quality conditions.

Abstract

Kurangnya informasi dan perhatian terhadap kawasan mangrove di Teluk Valentine menjadikan penelitian ini penting dilakukan. Seri Landsat 7 ETM + tahun 2003, dan 2015 digunakan sebagai data perekaman untuk memetakan mangrove dan melihat perubahan di wilayah ini. Penelitian ini bertujuan untuk memetakan perubahan ekosistem mangrove antara tahun 2003 dan 2015, dengan menggunakan citra Landsat berdasarkan metode OBIA dan membandingkan keakuratan metode OBIA dan piksel. Metode analis basis objek atau sering disebut klasifikasi berbasis objek digunakan untuk menganalisis sejauh mana perubahan tutupan mangrove. Hasil penelitian menunjukkan bahwa dengan menggunakan klasifikasi berbasis objek, tutupan hutan bakau sangat baik terdeteksi dengan akurasi 85-88%. Penerapan analisis ini relatif stabil pada periode pengamatan, kawasan ini telah mengalami perubahan dari tahun 2003 ke 2015 sebesar 1.2%, namun perubahan tersebut dimaksudkan penambahan mangrove alami. Perhatian pemerintah daerah diperlukan untuk melestarikan kawasan sebagai kawasan konservasi atau laboratorium alam mengingat kawasannya masih sangat bagus dan tidak dieksploitasi secara berlebihan oleh masyarakat sekitar kawasan Teluk Valentine.

Abstract

ABSTRACTCoral reef, mangrove, and seagrass bed are important ecosystems in coastal areas and small islands which plays critical roles in maintenance of shorelines and lands on small islands. Those ecosystems have mutual relationships in providing effective protection of lands and lives on small islands. The objectives of the research are to calculate, to valuate, and to determine ecological adaptive capacity small islands of Guraici Islands. Field work was carried out at all 17 islands of Guraici Islands, where data collection and calculations of each ecosystem adaptive capacity of coral reef, mangrove and seagrass bed were made. Values of adaptive capacity for each ecosystem are found to range between 0.0 and 1.0 whereas values of the ecological adaptive capacity of every single island in Guraici Islands range between 0.0 and 3.0. The results of this research indicate that all small island ecosystems studied in Guraici Islands can be grouped into three categories of adaptive capacity, they are “medium, low, and very low”. Values of coral reefs adaptive capacity range between 0.0 and 0.58. Values of mangroves adaptive capacity range between 0.0 and 0.51. Values of seagrass beds adaptive capacity range between 0.0 and 0.51. Data analysis made also shows that small island ecological adaptive capacity in Guraici Islands has also belonged to three categories “medium, low, and very low”, where all their adaptive capacity values range between 0.37 and 1.64. Ten islands are in “Medium” category, six islands in “low” category, and one island is in “very low” category.Key words: coral reef, ecological adaptive capacity, mangrove, seagrass-------ABSTRAKTerumbu karang (coral reef), mangrove dan padang lamun (seagrass bed), merupakan ekosistem penting di wilayah pesisir dan pulau-pulau kecil yang memegang peranan penting dalam melindungi garis pantai serta daratan pulau kecil.

Abstract

Fish stock in marine waters is always dynamic due to fluctuation in the annual total catch. Consequently, the estimate number of fish stock changes yearly, without exception in the southern coastal water of West Java. Fish stock condition in this region has not been reevaluated since 1999, the time before the separation of the province into West Java and Banten. This current study was intended to reassess the condition of fish stock utilization and estimate fish stock growth parameters in the southern coastal water of West Java in 2006. Data of fish production, effort, fish price, and effort cost for 14 years (1993-2006) are taken from the Office of Fisheries Agency of West Java Province. Effort data are standardized using relative fishing power method. Analysis of fish stock condition is carried out using Gordon-Schaefer bioeconomic model. Fish stock growth parameters are estimated using CYP, Uhler, and Hilborn and Walters methods. The results showed that utilization of marine fish resource in the southern coastal water of West Java is still in the condition of underfished and under effort. Estimates of fish stock growth parameters in this area are r = 3.8882, K = 22 080.355 ton, and q = 14.1775 × 10-7.Key Words: Fish stock assessment, southern coastal water, West Java, Gordon-Schaefer model.

Abstract

Pengukuran suhu permukaan laut melalui satelit telah banyak dilakukan. Mengingat berbagai sumber kesalahan pengukuran dalam metoda ini, beberapa peneliti serino meragukan ketepatan pengukurannya. Percobaan ini bertujuan untuk menganalisa ketepatan pengukuran suhu permukaan laut melalui satelit dan artinya bagi penelitian-penelitian di bidang perikanan dan kelautan. Pasangan data suhu permukaan laut yang diukur in situ melalui satelit dianalisa secara statistik. Analisa statistik menunjukkan bahwa 9 pasang data yang digunakan dalam percobaan ini. terlalu sedikit untuk dapatdigunakan sebagai dasar penarikan kesimpulan mengenai ketepatan pengukuran. Terlepas dari ini, banyak penelitian di bidang perikanan dan kelautan yang tidak terpengaruh oleh besarnya ketepatan pengukuran (bias), mengingat hanya gradien suhu secara horizontal yang diperlukan dan bukan nilai suhunya itu sendiri.Kala-kala kunci: NOAA-AVHRR. suhu permukaan laut, ketepatan, perikanan dan kelautan

Abstract

Gerakan oceanic frOllt telah sejak lama diduga sebagai suatu fenomena oseanografi fisik yang penting bagi proses-proses biologis di laut. Pergerakan front tersebut diyakini mencerminkan adanya pergerakan massa air laut. Oleh karena itu pergerakan front sangat penting untuk mempelajari proses transportasi partikel di laut terlllasuk transportasi telur larva ikan. Penelitian mengenai pergerakan massa air akibat hembusan angin telah banyak dilakukan. Namun demikian pengaruh arus panas Gulf Stream terhadap fenomena tersebutbelum diteliti secara serius. Penelitian ini ditujukan untuk memperlihatkan pengaruh Gulf Stream terhadap pergerakan front yang dideteksi melaui citra satelit. Pergerakan front di laut dapat dideteksi melalui citra suhu perrmmukaan laut mengingat didaerah front ini terjadi gradien suhu yang lebih tinggi dibandingkan dengan daerah lainnya. Dalam penelitian ini dapat dilihat bahwa pergerakan front (gerakan offshore-ol ore) di pantai North Carolina, Amerika Serikal, diakibatkan oleh gerakan berbelok-beloknya arus panas Gulf Stream dan fenomena terbentuknya filamen atau bentukan lidah (tonguelike structure) dari Gulf Stream . Pergerakan ini kelihatannya merupakan proses oseanografi yang paling penting mempengaruhi kelangsungan hidup larva ikan di pantai timur-Iaut Amerika Serikat.Kata-kata kunci : satelit, oceanic front, Gulf Stream, pantai, pergerakan massa air, transpor-tasi larva ikan ,estuarine -dependent fish.
