Abstract

The purpose of this study was to determine the type, dimensions and composition of nematocytes in Scleractinia, Acropora florida and Acropora divaricata.  This research was conducted in South Motandoi Beach, East Pinolosian District, South Bolaang Mongondow Regency, North Sulawesi for five (5) months; from February to June 2019.  The method of this research was observation using student-t statistical data analysis. Microbasic p-Mastigophore type-II (MpM-II) and Holotricous isorhiza (HI), while A. divaricata only has type-II Microbasic p-Mastigophore (MpM-II) nematocytes.  The nematocytes dimension showed an average capsule length of MpM II in A. florida of was 262.32 µm and A. divaricata was 125.15 µm, mean capsule width of MPM II in A. florida was 67.01 µm and A. divaricata was 31.95 µm, and the average length of mpM II on A. florida was 154.44 µm, and A. divaricata was 70.97 µm.  Nematocytes composition showed that MPM II in A. florida was 95.56% and HI was 4.44%, while the composition of MPM II nematocytes in A. divaricata was 100% and HI was 0%.  Student t-test showed that the ratio of 2 average values of capsule length, capsule width, and MPM II stem length from two populations of A. florida and A. divaricata were not significantly different (P> 0.05).   It can be concluded that both types of A. florida and A. divaricata corals have different types and composition of nematocytes however their size dimensions are not significantly different.  Further studies are important to examine genetic and environmental factors to find out how much the kinship relationship between the two types of those coral.Keywords: Acropora florida, Acropora divaricata, HI, Scleractinia coral, MpM II, nematocytes

Abstract

The purpose of the community partnership program is to increase the capacity of independent and sustainable marine fish farmers groups.  Specific targets are 1) Increasing the quantity and quality of fish products from marine aquaculture in floating net cages, and 2) Enhancing partners' understanding and skills in terms of effective and efficient marine fish aquaculture technology in floating net cages. The main problems recorded, namely: 1) lack of knowledge of marine fish aquaculture technology in floating net cage; 2) fish harvest time that requires a long time, and 3) poor financial management.  To overcome these problems, an approach is carried out through direct education and training, mentoring, and management of fisheries business management in the field to partners.  After that, each trainee in the partner group is given the opportunity until they can do it themselves.  The target that will be achieved at the end of this education and training is that all group members and their families have knowledge of: 1) superior marine fish polyculture technology in floating net cage and 2) good financial management. Keywords: Fish cultivator group, floating net cage, South Motandoi village, financial management, marine fish polyculture technologyAbstrakTujuan program kemitraan masyarakat (PKM) adalah meningkatkan kapasitas kelompok pembudidaya ikan laut yang mandiri dan berkelanjutan. Target khusus adalah 1) peningkatan kuantitas dan kualitas produk ikan hasil budidaya laut dalam karamba jaring apung, dan 2) peningkatan pemahaman dan ketrampilan mitra dalam hal teknologi budidaya ikan laut dalam karamba jaring apung yang efektif dan efisien. Permasalahan utama yang terekam, yaitu: 1) kurang pengetahuan tentang teknologi budidaya ikan laut dalam karamba jaring apung (KJA); 2) waktu panen ikan yang membutuhkan waktu yang lama, serta 3) pengelolaan keuangan yang kurang baik. Untuk mengatasi masalah tersebut dilakukan pendekatan melalui penyuluhan dan pelatihan, pendampingan, dan pendidikan manajemen usaha perikanan secara langsung di lapangan kepada mitra. Setelah itu, setiap peserta pelatihan dalam kelompok mitra tersebut diberikan kesempatan sampai mereka bisa melakukannya sendiri.  Target akhir yang dicapai dalam PKM ini adalah semua anggota kelompok maupun keluarganya mempunyai pengetahuan tentang: 1) teknologi polikultur budidaya ikan laut dalam karamba jaring apung yang unggul, dan 2) manajemen keuangan yang baik.  Kata-kata kunci: Kelompok pembudidaya ikan, karamba jaring apung, Desa Motandoi Selatan, manajemen keuangan, teknologi polikultur ikan laut
