The mangrove ecosystem has functions that important for econimic and ecology. Increased utilization activities that are damaging accompanied decline mangrove area, it is appropriate rehabilitaion condition and maintenance mangrove ecosystem. Improvement effort rehabilitation mangrove ecosystem. The aim mangrove rehabilitation effort for restore ecosystem. Study aimed to determine the extent of damage level, area suitability biophysical and mangrove specieses planted. The survey method used measurement directly to determine the damage level and area suitability biophysical assesment. The Results showed mangrove ecosystem destruction overall research stations are medium damaged condition. Analysis suitability index (IKW) showed that mangrove ecosystem overall stations were suitable rehabilitation area. The mangrove specieses are Rhizophora sp, Bruguiera sp, Sonneratia sp, Xylocarpus sp, Scyphiphora hydrophyllacea and Heritiera littoralis sustable to planting.
The shellfish craft business is not only profitable for business actors, but also provides other benefits, including opening up employment opportunities for the community, increasing community creativity due to growing market demand and maintaining the product as a quality work of art. The output targets are household equipment (tissue boxes), interior accessories (wind chimes, door/window curtains) and souvenirs (key chains, brooches). Implementation methods include counseling, demonstration, training and coaching in the development of shellfish waste as a business opportunity. The training activity was successful because the enthusiasm of the participants was so great in pursuing the art of shellfish craft. Various forms of products and models produced are very varied. The products produced are tissue boxes, wind chimes, door/window curtains, key chains and brooches. The formation of a craft group “Creative Kastil” in the context of the sustainability of training activities.
AbstrakLamun (Seagrass) merupakan salah satu ekosistem penting diwilayah pesisir yangberperan penting baik secara ekologis dan ekonomis. Keberadaan lamun mendukungkehidupan berbagai jenis biota laut. Penelitian ini bertujuan mengidentifikasi jenis-jenislamun yang berada di perairan pantai Rua, Mengetahui kepadatan, pola sebaran,keanekaragaman jenis, dan dominansi serta asosiasi antara spesies. Penelitian ini dilakukandengan metode garis transek dan kuadrat. Hasil penelitian menunjukkan bahwa terdapat 4jenis lamun di perairan pantai Rua yang terdiri dari Cymodocea rotundata, Enhalusacoroides, Halodule pinifolia dan Thalassia hemprichii. T. hemprichii adalah jenis dengankepadatan tertinggi di perairan Rua yaitu 16,70 ind/m2, serta E. acoroides, memilikikepadatan terendah yakni 5,77 ind/m2. Jenis lamun yang ditemukan di lokasi penelitianseluruhnya memiliki pola sebaran mengelompok dengan keanekaragaman yangdikategorikan rendah yaitu sebesar 1,32, serta indeks dominasi sebesar 0,27.

Pengembangan wisata mangrove memerlukan kesesuaian sumberdaya dan lingkungan yang sesuai dengan yang disyaratkan. Kesesuaian karakteristik sumber daya dan lingkungan untuk pengembangan wisata dilihat dari aspek keindahan alam, keamanan dan keterlindungan kawasan, keanekaragaman biota, keunikan sumber daya dan aksesibilitas. Tujuan penelitian yaitu menghitung indeks kesesuaian kawasan untuk pengembangan ekowisata mangrove, menghitung daya dukung kawasan dan mengidentifikasi jenis kegiatan wisata yang dapat dilakukan dalam kawasan mangrove. Metode yang digunakan adalah metode survei yaitu pengukuran secara langsung untuk mengetahui kondisi biofisik mangrove. Hasil analisis Indeks Kesesuaian Wisata (IKW) baik stasiun i, stasiun 2 dan stasiun 3 maupun secara keseluruhan menunjukkan kawasan hutan mangrove di Desa Tuada Kecamatan Jailolo berada pada kategori S1 (sangat sesuai). Jumlah Daya Dukung Kawasan (DDK) untuk kegiatan tracking adalah 34 orang/hari, kegiatan piknik sebanyak 56 orang/hari dan kegiatan camping sebanyak 13 orang. Total daya dukung kawasan wisata mangrove Desa Tuada adalah 102 orang/hari. Aktivitas kegiatan ekowisata mangrove Desa Tuada setiap hari dibuka mulai jam 06.00 – 18.00 WIT.

Pengambilan sampel dengan mengikuti kegiatan operasi penangkapan.dengan nelayan. Operasi penangkapan ikan dilakukan sebanyak 2 kali setiap minggu dan dilakukan selama satu bulan. Hasil tangkapan diambil secara acak (random sampling). Hasil tagkapan selanjutnya dilakukan pengukuran panjang cagak dan body girth. Penentuan tingkat kematangan gonad (TKG) yang dilakukan secara visual dengan melihat bentuk, warna serta perkembangan isi gonad.Hasil penelitian diperoleh ukuran pertama kali matang gonad ikan kembung (Rastrelliger sp) yang tertangkap di perairan Desa Sidangoli Dehe dengan kisaran panjang cagak 250,7 mm sedamgkan ukuran mata jaring insang minimum yang sebaiknya digunakan untuk penangkapan ikan kembung (Rastrelliger sp) yaitu 11,8 cm (4,6 inchi). Kata Kunci : Matang gonad, mata jaring, Rastrelliger sp, Sidangoli Dehe Abstract: The purpose of this study is to determine the size of first-time gonads and the size of gill-net for catching mackerel (Rastrelliger sp) in Dehe Sidangoli waters. Sampling by taking part in arrest operationswith fishermen. Fishing operations are carried out twice a week and carried out for one month. The catch is taken randomly. The result of the next tag is the measurement of the fork length and body girth. Determination of the level of gonad maturity (TKG) that is done visually by looking at the shape, color and development of gonadal contents. The results showed that the first size of mackerel gonad (Rastrelliger sp) that was caught in the waters of Sidangoli Dehe Village with a fork length of 250.7 mm was the minimum size of the gill-net which should be used for catching mackerel (Rastrelliger sp) which was 11.8 cm (4.6 inches).
