Abstract

Macrozoobenthos are benthic animals commonly found in substrate-based ecosystems, such as mangrove forests. Their presence in mangrove ecosystems significantly influences the decomposition activities within the substrate or sediment layers. The aim of this study was to identify species composition, species density, community structure of macrozoobenthos, and their vertical distribution within sediments on mangrove ecosystem in Ternate City. The study was conducted from August to September 2021 using the line transect method, with macrozoobenthos samples collected through iron pipe corers. Data analysis included species density, species diversity, dominance index, evenness index, niche width, microhabitat niche overlap, and the relationship between macrozoobenthos density and depth. The results showed that the macrozoobenthos species composition consisted of two species (Uca spp. and Nereis spp.), with a total of 25 individuals. Species diversity within mangrove ecosystem was found to be low, with one dominant species and a relatively even distribution. The species with the broadest habitat niche was the worm (Nereis spp.), while significant microhabitat niche overlap occurred between the worm (Nereis spp.) and the crab (Uca spp.). Simple linear regression analysis indicated that substrate depth did not correlate with macrozoobenthos species density.Keywords:aquaticbenthoscoastalfaunaterrestrial

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

Penelitian ini bertujuan untuk mendeskripsikan data mengenai partisipasi orangtua terhadap pembentukan perilaku sosial remaja di Rw 01 Desa Kaliwulu Kecamatan Plered Kabupaten Cirebon, perilaku sosial remaja di Rw 01 Desa Kaliwulu Kecamatan Plered Kabupaten Cirebon dan mengetahui faktor-faktor yang mempengaruhi pembentukan perilaku sosial remaja di Rw 01 Desa Kaliwulu Kecamatan Plered Kabupaten Cirebon. Hasil penelitian ini yang terkait dengan partisipasi orangtua terhadap pembentukan perilaku sosial remaja adalah orangtua menggunakan banyak pola asuh yang diterapkan kepada anaknya ada yang bersifat otoriter dan ada pula yang biasa-biasa saja seperti pola asuh secara demokratif dan laissez-faire. Para orangtua kebanyakan mengikutsertakan anak mereka dalam kegiatan keagamaan serta kemasyarakatan, diharapakan anak mereka nantinya dapat hidup bermasyrakat dengan baik serta berperilaku sosial yang baik. Adapun faktor-faktor yang bisa mempengaruhi pembentukan perilaku sosial remaja yaitu faktor pendidikan, masyarakat, keluarga dan teman sebaya atau sepermainan, media masa, perkembangan IPTEK.Kata Kunci: Partisipasi dan Perilaku Sosial
