Abstract

The objectives of present study were to determine the distribution of sediment associated with shoreline changes and to analyze the beach dynamics in Rening Beach. Sediment samples were taken from seventeen sampling points spread along the beach, and then followed by the lab test using granulometri method to determine the characteristics of sediment. Shoreline change was analyzed using analysis of satellite imagery in 2011, 2014 and 2016, while the sediment transport were analyzed using Hjulstrom graph. Then, Rening Beach dynamics can be analyzed. Sediment test results showed that sediment type in Rening Beach was dominated by sand with diameter of between 0.25-5 mm. The ocean currents movement was dominantly to the west. The results of shoreline change analysis between the years 2011-2016, and Hjulstrom graph analysis showed the same pattern that Rening Beach was eroded. The Rening Beach was high dynamics with subjected to beach erosion in the form of littoral drift due to longshore currents.Penelitian ini bertujuan untuk mengetahui perubahan garis pantai, transpor sedimen dan dinamika pantai di Pantai Rening. Pengambilan data arus dan sampel sedimen diambil dari tujuh belas titik pengambilan sampel yang tersebar merata di sepanjang perairan Pantai Rening. Sampel sedimen kemudian diujikan di laboratorium menggunakan metode granulometri untuk mengetahui karakteristik sedimen. Perubahan garis pantai dianalisa menggunakan analisis peta citra satelit tahun 2011, 2014 dan 2016, sedangkan pola transpor sedimen dianalisa menggunakan grafik Hjulstrom. Dari hasil analisa perubahan garis pantai dan transpor sedimen, dapat dianalisa dinamika Pantai Rening. Hasil uji sedimen menunjukkan bahwa jenis sedimen didominasi oleh pasir sedang dengan diameter antara 0.25-5 mm. Pergerakan arus dominan mengarah ke arah barat. Hasil analisis perubahan garis pantai antara tahun 2011-2016, dan analisa grafik Hjulstrom menunjukkan pola yang sama bahwa pada Pantai Rening mengalami erosi dan mundurnya garis pantai. Dinamika Pantai Rening cukup tinggi dengan kecenderungan terjadi erosi pantai berupa littoral drift akibat arus sejajar pantai.

Abstract

Gastropods are one of the macrobenthos associated with seagrass ecosystems. The purpose of this research is to determine the structure of the gastropod community in the seagrass ecosystem in the Bama waters of Baluran National Park. Collecting data on gastropods in seagrass ecosystems uses quadrat transects. The research was conducted in February 2024. Based on the research results, it was found that the richness of gastropod species in the seagrass ecosystem in the waters of Baluran National Park was in the low category at each station. The gastropod species diversity index value in this study was in the low category. The evenness index has a stable category, while the dominance index in this study does not have species dominance in gastropods. Seagrass density in this study was in the rare and dense categories.

Abstract

Upaya penanaman mangrove menjadi sangat penting bagi kelestarian ekosistem pesisir. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan kesadaran masyarakat tentang pentingnya mangrove dan melibatkan mereka dalam upaya pelestarian lingkungan. Melalui penanaman mangrove, diharapkan masyarakat dapat memahami peran penting mangrove dalam menjaga keseimbangan ekosistem pesisir dan meningkatkan kualitas hidup. Kegiatan penanaman mangrove dapat memberikan dampak positif bagi lingkungan dan masyarakat sekitar serta menjadi langkah awal dalam upaya pelestarian ekosistem mangrove. Penanaman mangrove efektif untuk menstabilkan pesisir dari erosi dan sedimentasi serta meningkatan keanekaragan hayati. Mangrove yang baru ditanam berfungsi sebagai habitat bagi berbagai jenis biota laut dan satwa liar. Penanaman mangrove memberikan manfaat sosial ekonomi bagi masyarakat diantaranya peningkatan pendapatan dari hasil perikanan dan pengembangan ekowisata.

Abstract

The seagrass ecosystem is a habitat and food source for fish and other aquatic biota. One of the biota commonly found in seagrass beds is gastropods . This aim research was carried of identifying the composition of gastropod species, assessing ecological indices which include species density, species diversity, species dominance, species evenness, distribution patterns of gastropods and their use in the seagrass ecosystem on Maitara Island. Gastropod sampling was carried out at low tide. The gastropod samples determined based on morphological characteristics such as shell shape, shell color, shell mouth opening and spiral circle. Based on the research results, the composition of gastropod species found in the seagrass ecosystem is 32 species. The density of gastropod species was highest in the seagrass ecosystem on Maitara Island, at each different station. The highest density of gastropod species was Morula uva and Strombus luhuanus, while the lowest density was Trhocus maculatus, Littorina scabra and Nassarius sp. The diversity of gastropod species at all stations is classified as moderate. For the dominance index at all stations, there is no dominant species in the category. The evenness of species at station 1 and 4 is classified as more evenly distributed, while at stations 2 dan 3 it is classified as very evenly distributed. The overall distribution pattern of gastropods is classified as clustered and random. Totals 32 species of gastropods, 10 of them are used by the people of Maitara Island as food for consumption.Keywords:benthicconditionimpacttropicalsurvival

Abstract

Seagrass ecotourism is a tourism activity based on seagrass ecosystem as an educational tour by seeing the ecology of seagrass meadows and associated biota. Conservation awareness and improving community welfare, seagrass ecotourism is a nature-based tourism strategy with the aim of environmental conservation and containing aspects of community education and culture. Determining the sustainability status of seagrass ecosystem management is very important as a basis for future policy planning. The sustainability of seagrass ecosystems needs to be protected, so a policy strategy is applied in sustainable seagrass ecosystem management. The objectives of the study are: 1) determining the sustainability status of ecotourism-based seagrass ecosystem management based on ecological, economic and social dimensions, 2) determining the policy strategy for ecotourism-based seagrass ecosystem management. The results of the study obtained the sustainability status of ecotourism-based seagrass ecosystem management based on ecological dimensions is quite sustainable while the economic and social dimensions are less sustainable. The strategy for sustainable policy for managing seagrass ecosystems based on ecotourism on Maitara Island, Tidore Islands, namely education about seagrass ecosystems for the community, managing seagrass ecosystems based on ecotourism, increasing seagrass rehabilitation programs, maximum limits for carrying capacity of seagrass ecotourism, training for developing managers of seagrass ecotourism based on ecosystems, increasing job opportunities and business opportunities, legality of seagrass areas as conservation areas in the tourism utilization zone category and strengthening laws and institutions.Keywords:analysismultidimensionalsmall islandsustainabilitytourism

Abstract

Zooxanthellae are single-celled microalgae that live symbiotically in coral tissue. The porpose of this study was to determine the abundance of zooxanthellae in massive and branching corals. The research method used was descriptive analysis. The sampling technique used direct field sampling by chisels, both on massive coral reefs or branching coral reefs. Observation of zooxanthellae was conducted in the laboratory using a microscope. The results obtained from the research indicate that massive corals have a relatively higher abundance of zooxanthellae with values of 109 x 105 cells/cm than branching corals with values of 73 x 105 cells/cm. In addition, massive corals are more resistant to bleaching than branching corals due to their large reserves of zooxanthellae and their ability to adapt to environmental stress.Keywords:AbundanceZooxanthellaeMassiveBranching
