Habitat Preference and Spatial Distribution of Juvenile Blue Swimming Crab (Portunus pelagicus) in the East Lampung Coastal Waters, Lampung Province
Get PDFInformation on habitat preferences of the blue swimming crab (BSC) juvenile and its spatial distribution is one of the factors behind the successfulness of its sustainable management. This information is needed to provide input for management strategy by considering juvenile crabs and their habitat as important aspect. The purpose of this study is to elucidate habitat preferences, abundance and biomass distribution of BSC juvenile in the east Lampung coastal waters. The research was conducted in September-October 2018, which was located in east Lampung coastal waters, Province Lampung. Spatial distribution through estimation of abundance and biomass of BSC juvenile were relatively high and concentrated in the Gambas and Wako regions at stratification of 2-4 miles from the coastline. The BSC juvenile does not appear to have a high preference to the Kuala Penet coastal habitat condition; it is considered because of low value of abundance, biomass, and Habitat suitability index (HSI). The value of HSI in the Kuala Penet Coastal region is also lower than other locations due to abiotic and biotic factors for supporting the crabs at juvenile stage

No full textSalah satu fungsi ekologis ekosistem mangrove adalah sebagai penyimpan karbon. Namun di sisi lain juga berpotensi menimbulkan emisi gas rumah kaca melalui degradasi serasah meskipun nilainya jauh dibandingkan nilai serapan tersebut. Berdasar pada hal tersebut, pengelolaan mangrove sebagai Ruang Terbuka Hijau (RTH) di kawasan sungai Tallo Kota Makassar perlu untuk dipertimbangkan dengan mengikutsertakan peran serta masyarakat dan pemerintah selaku pemangku kepentingan. Penelitian dilakukan dengan melakukan studi dan telaah literatur terkait serta wawancara responden berkenaan dengan persepsi dan partisipasi pengelolaan mangrove. Hasil penelitian menunjukkan bahwa total serapan karbon mangrove di sungai Tallo kota Makassar yaitu 351,02 tonCO2/ha, suplai oksigen 255,29 O2-equivalen/ha, dan potensi pemanasan global yaitu 252,41 mg/m2/jam yang terdiri dari 194,33 mg/m2/jam gas CO2, 15,76 mg/m2/jam gas CH4, dan 42,33 mg/m2/jam gas N2O. Hasil analisis persepsi dan partisipasi masyarakat menunjukkan bahwa sekitar 89% masyarakat sangat setuju dan mendukung pemerintah dalam upaya pengelolaan mangrove sebagai ruang terbuka hijau. Berdasarkan hal tersebut, maka ekosistem di Sungai Tallo sangat sesuai dikelola untuk ruang terbuka hijau sebagai penyuplai udara segar dan penyerap CO2 bahkan sebagai peredam kebisingan dari mesin kendaraan ataupun industri di kota Makassar.One of the ecological functions of mangroves ecosystem is to store carbon. Yet, on the other hand it also has the potential to cause greenhouse gas emissions through litter degradation even though its value is lower compared to the absorption value. Based on these two facts, mangrove management as a Green Open Space in the Tallo river area of Makassar City needs to consider involving the participation of the community and the government as stakeholders. The research was conducted by desk work, literature study and respondent interviews regarding perceptions and participation in mangrove management. The results showed that the total uptake of mangrove carbon in the Tallo river in Makassar city was 351.02 tons CO2/ha, oxygen supply 255.29 O2-equivalent/ha, and the potential for global warming was 252.41 mg/ m2/hour consisting of 194, 33 mg/m2/hour of CO2 gas, 15.76 mg/m2/hour of CH4 gas, and 42.33 mg/m2/hour of N2O gas. The results of community perception and participation analysis show that around 89% of the community strongly agreed and supported the government in the effort to manage mangroves as a green open space. Based on this, the ecosystem in the Tallo river is very suitable to be managed for green open space as fresh air supplier and CO2 adsorber as well as a noise reduction from vehicle or industrial engines in Makassar city
