Penelitian ini bertujuan untuk: mengkaji kondisi manajemen usaha bagan, menganalisis penerimaan usaha dan pendapatan nelayan pemilik, menganalisis kelayakan usaha bagan, menganalisis faktor-faktor yang mempengaruhi produksi usaha bagan, dan merumuskan strategi pengembangan usaha bagan di Desa Sathean, Kecamatan Kei Kecil. Metode yang digunakan terdiri atas survey descriptive (deskriptif survei)dansurvey explanatory (eksplanasi survei). Hasil penelitian memperlihatkan bahwa, manajeman usaha penangkapan ikan dengan alat tangkap bagan yang telah berjalan dengan baik adalah manajemen produksi dan manajemen pemasaran, sedangkan manajemen permodalan masih sulit untuk dijalankan. Pendapatan nelayan pemilik usaha bagan di Desa Sathean, Kecamatan Kei Kecil dengan rata-rata 264 trip adalah Rp 282.120.000,- hingga Rp 815.996.000,- atau rata-rata Rp 355.458.000,- tiap unit usaha. Usaha penangkapan ikan dengan alat tangkap bagan di DesaSathean layak untuk diusahakan. Faktor-Faktor yang mempengaruhi produksi usaha bagan adalah frekuensi melaut, biaya operasional, waktu/lama melaut, dan umur. Strategi pengembangan usaha penangkapan ikan dengan alat tangkap bagan di desa Sathean Kecamatan Kei Kecil Kebupaten Maluku tenggara, meliputi: 1). Pengembangan usaha bagan kepada lembaga pemberi kredit untuk menambah modal usaha; 2). Program kebijakan yang diarahkan pada pengembangan teknologi dan jumlah alat tangkap bagan; 3). Pelaksanaan penelitian yang diarahkan pada peningkatan hasil tangkapan usaha, pengelolaan permodalan, ketidak efisiensi penggunaan biaya opersional dan waktu melaut serta pengembangan pemasaran hasil tangkapan bagan; dan 4) Peningkatan fungsi manajemen produksi, yakni mengefisiensikan penggunaan biaya operasional dan waktu melaut, dan manajemen pemasaran.
Inflammatory disease in gastric tract called Inflammatory Bowel Disease (IBD), particularly colon, in general, results from the use of non-steroid anti-inflammatory drug, such as indomethacine. The use of natural material, such as mas ngur oyster (Atactodea striata) as traditional medicine has been long known by people in Kei Islands–Southeast Mallucas. This study is aimed at measuring the ability of active compounds of this oyster extract in reducing NF-κB and TNF-α expression and showing the histological image of indomethacine-induced rat ileum with IBD after treatment with mas ngur oyster extract. It used 8-12 week old male rats (Rattus norvegicus) of 150 - 200 g BW. The rats were divided into 3 groups, healthy group, sick group (induced with 15 mg/kg BW of indomethacine), and treatment group (orally induced with indomethacine at a dose of 15 mg/kg BW then treated with mas ngur oyster extract at the dose of 100, 400, 700 mg/kg BW). Indomethacine induction at the dose of 15 mg/kg BW and mas ngur oyster extract therapy were orally administered. NF-κB and TNF-α expressions were measured using immunohistochemicals, and the histological image used Hematoksilin-Eosin staining. Results showed that extract therapy gave significant effect (P<0.05) at the effective dose of 400 mg/kg BW that could reduce 86.421% of NF-κB expression and 60.972% of TNF-α expression in the rat ileum and result in tissue recovery of the IBD rat’s ileum after the therapy.
