Abstract

A study was carried out to assess the present status of blue swimmer crab (Portunus pelagicus) in Lancang Island, incorporating identification of fishing ground, also measurement of environmental condition and crab biometry. Monthly catch assessment was performed on JuneSeptember 2015 at three landing bases using structured questionnaire and morphometric sampling of minimum randomly selected 30 crabs. Bathymetric survey was conducted to produce depth-contoured maps combined with certain oceanographic parameters (sea surface temperature, salinity, water clarity, total suspended solids, dissolved oxygen, and nitrate-NO3) measured at 15 sampling sites. A grid map was produced to identify key areas of crab fishing grounds, recruitment habitat, and spawning habitats. During southeast monsoon, main fishing ground was distributed in the western and southern part of Lancang Island (grid C3, C4, and D5). In general, crab yields were dominated by female (66.9%) and 43.8% of them were bearing eggs. Four size classes were determined from frequency distribution of carapace width (Class 1 = 7.0-10.6 cm; Class 2 = 10.7-14.2 cm; Class 3 = 14.3-17.8 cm; and Class 4 = 17.9-21.5 cm), with Class 2 as the most prominent catch. Referring to ontogenetic migration trait of the species, presumed recruitment habitat for blue swimmer crab in Lancang Island is located at A6, where abundant juveniles were harvested in the area with strong oceanic influence and depth range of 24-30 m. Spatial coherence on the distribution of bearing egg female with several environmental parameters (sea surface temperature, salinity, and dissolved oxygen) indicates strong estuarine influence is required for crab spawning habitat at C3 and

Abstract

Geographical Information System (GIS) is a computer system used to collect, examine, integrate, and analyze information related to surface of the earth. One of the benefits of using GIS is to determine the suitability of a marine tourism area, which is the purpose of this study, the results showed that the Pinangsori sub-districts "Appropriate" and "Conditionally Fit" to be developed for marine tourism namely for diving tourism (42,29 suitable; 49,68 Ha conditionally suitable) and fishing tourism (49,01 Ha suitable; 100,45 Ha conditionally suitable). Regional carrying capacity of 94 people/day for diving and 8 people/day for fishing tourism.

Abstract

Muara Nauli Beach area has a charm in the form of a sloping white sandy beach and is broad enough and the waters aspects are conducive to being a marine ecotourism. This research was conducted in December2019 at Muara Nauli Beach, Sorkam Sub-district, Central Tapanuli District. The purpose of this study is to assess the suitability and carrying capacity of the area in Muara Nauli Beach as a marine tourismdestination. The method using are calculate of tourism suitability index and carrying capacity with geographical information system technology. The data used are primary data and secondary data. Primary data were obtained from field observations and interviews. Whereas secondary data was obtained from related institutions. The results obtained from the tourism suitability index for beach recreation tourism are the "suitable" category with an area of 7.24 Ha and the "conditional suitable" category with an area of 357.04 Ha. For swimming tourism of "suitable" category with an area of 320.3 Ha and "conditional suitable" category with an area of 51.52 Ha. The total carrying capacity of the region for swimmingtourism in one day is 43 people and for beach recreation tourism is 463 people. Therefore, the Muara Nauli Beach is feasible to be developed by the government to be used as marine ecotourism such as beachrecreation tourism and swimming tourism.

Abstract

Lamun merupakan tumbuhan laut yang mampu menyimpan karbon dalam bentuk biomassa yangdiserap melalui proses fotosintesis, sehingga lamun memainkan peran yang luar biasa dalam mitigasiisu perubahan iklim global. Penelitian ini dilaksanakan pada bulan April 2016. Analisis biomassadan cadangan lamun dilakukan di Laboratorium Kimia Laut, Fakultas Perikanan dan Ilmu Kelautan,Universitas Riau. Hasil penelitian menunjukkan bahwa terdapat 6 species lamun pada plot, dimanaspecies terbanyak adalah C. rotundata dan species paling sedikit jumlahnya E. acroides. Nilaibiomassa total dan cadangan karbon total lamun berturut-turut adalah 213,10 ton bk/ha dan 72,46ton C/ha. Cadangan karbon pada ekosistem lamun di lokasi penelitian ini tidak memiliki perbedaansignifikan pada jarak 0 m, 50 m dan 100 m. Tingginya potensi biomassa dan cadangan carbon padaekosistem padang lamun menggambarkan besarnya peran ekosistem ini dalam menanggulangidampak buruk dari pemanasan global dengan cara menyerap karbon dioksida dan menyimpannyadalam bentuk biomassa. Hal ini dapat dijadikan sebagai acuan dalam membuat perencanaan mitigasiisu perubahan iklim global dan kegiatan konservasi pada ekosistem ini.
