Judul: Analisis dampak perdagangan ikan karang hidup konsumsi life reef fish food terhadap sumberdaya perikanan: studi kasus di Provinsi Sulawesi Selatan
Abstrak: Penelitian ini bertujuan untuk mengetahui dampak perdagangan ikan karang hidup konsumsi (LRFF) terhadap sumberdaya perikanan di Indonesia. Seperti diketahui bahwa LRFF di Indonesia telah mengalami eksploitasi berlebih akibat praktek penangkapan yang tidak berkelanjutan dan tingginya permintaan di pasar internasional. Penelitian ini menggunakan pendekatan analisis bioekonomi dan analisis simulasi. Pendekatan analisis bioekonomi bertujuan untuk memperoleh tingkat optimal eksploitasi LRFF dan pendekatan analisis simulasi bertujuan untuk memprediksi dampak perdagangan LRFF. Hasil penelitian menunjukkan harga mempunyai dampak terhadap tingkat eksploitasi LRFF. Harga yang tinggi akan meningkatkan upaya penangkapan dan mengurangi suplai perikanan di perdagangan dalam jangka panjang,

Judul: Politik Seafood Savers Ikan Konsumsi Karang Hidup (Studi Kasus di Kabupaten Wakatobi, Sulawesi Tenggara)
Abstrak: Live reef food fish (LRFF) which is a commodity found in Wakatobi has emerged in the era of the 1992’s up to present. The commodities are an expansion phenomenon of a global fishery which is very dynamic. The dynamic trading on the LRFF has affected some problems which relate to an integrated factor linking to social, economy, ecology and policy making factors. These transboundary trading have involved several actors to engage into a global network live reef food fish commodity found from fisherman-middleman(coordinator)-exporters and consumers. The commodities have traded to be based on the assumption of the common property resources due to the open access which is embedded on the LRFF. The practices of the type of trading has effected to the overfishing that has lead to the decline of a fish stock. Moreover, this practice has impacted to the change of the structures of social production, the trading network and market policies. Seafood Savers has a respond to the market failure due to the degradation of the LRFF commodities. Seafood Savers program is a market instrument for LRFF management which is a sustainability orientation. The program of Seafood Savers is an important key to successful implementation of the responsibility fisheries practice on the LRFF in Wakatobi as being in a pilot project supervised by WWF Indonesia. This study used a qualitative approach with constructivism paradigm. This research also was conducted in the interaction with the political ecology and the intuitional analysis to contribute to the study of a sustainability policy on the LRFF. Results of this study indicate that there has been no significant change occurred in the use of the commoditization of live reef fish food. Politics of Seafood Savers have not been able to answer the problem of fishermen on the field. Seafood Savers comes as a power tool market is trying to shed the patron-client ties (Coordinator-fisherman) and tried to lift Seafood Savers policy to accommodate into the form of legal partnership working arrangements between market, state and community.

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
