Judul: Induced Maturation of Female Striped Catfish Pangasianodon hypophthalmus Broodstock in Non-spawning Season using Hormone Combination of Pregnant Mare Serum Gonadotropin (PMSG) and Antidopamine
Abstrak: Budidaya ikan patin siam memiliki kendala pada ketersediaan benih yang sulit di musim kemarau disebabkan oleh minimnya induk ikan patin siam yang matang gonad. Penelitian ini bertujuan menginduksi dan mempersingkat waktu pematangan gonad di luar musim pemijahan dengan menggunakan kombinasi hormon PMSG dan antidopamin. Penelitian menggunakan metode rancangan acak lengkap, terdiri atas 4 perlakuan dengan masing-masing 10 kali ulangan diinduksi dengan hormon secara intramuskuler, interval penyuntikan setiap 2 minggu. Dosis yang diberikan adalah PMSG 0 IU/kg ikan + antidopamin 10 μg/kg ikan, PMSG 5 IU/kg ikan + antidopamin 10 μg/kg ikan, PMSG 10 IU/kg ikan + antidopamin 10 μg/kg ikan, dan kontrol menggunakan larutan fisiologis. Hasil terbaik ditunjukkan oleh perlakuan PMSG 10 IU/kg ikan + antidopamin 10 μg/kg ikan dengan menghasilkan persentase matang gonad mencapai 100% populasi dengan TKG IV dalam waktu 6 minggu (3 kali penyuntikan), sedangkan pada kontrol hanya 30% matang gonad dalam waktu 8 minggu. Kombinasi hormon PMSG dan antidopamin dapat menginduksi percepatan pematangan gonad calon induk ikan patin siam di luar musim pemijahan. Hal ini memberikan harapan produksi induk matang gonad dan benih ikan patin dapat dilakukan sepanjang tahun.

Judul: Pematangan Gonad Calon Induk Ikan Patin Siam Pangasianodon hypophthalmus di Luar Musim Pemijahan Menggunakan Hormon Pregnant Mare Serum Gonadotrophin (PMSG)
Abstrak: The Problems on catfish culture is a scarcity of seeds in the dry season due to the lack of availability of the broodstock catfish mature gonads. The purpose of this research was to induce gonad maturity catfish broodstock hormonally outside the spawning season with PMSG hormone. The tested fish were injected with treatment 0 IU / kg fish, 5 IU / kg of fish and 10 IU / kg fish. Pregnant Mare Serum Hormone Gonadotrophin (PMSG) is a hormone that can stimulate gonadal maturation in the catfish because it contains a lot of FSH and LH bit. PMSG hormone induced by injection intramuscularly given 2 weeks for 8 weeks. The results showed that the PMSG is able to accelerate the maturity of gonads catfish broodstock. The best dosage is 5 IU PMSG / kg fish / 2 weeks / 8 weeks. The results obtained percentage of mature fish gonads reaches 100% at week 8, whereas the treatment 0 IU / kg fish reach 30% the end of the study period. PMSG can be used to accelerate the maturity of gonads in brood fish catfish that seed production can be produced throughout the year.

Judul: Basis of Social Theories for Social Enterprises: Integrative Literature Review
Abstrak: Social enterprise is a hybrid organization aiming to achieve economic and social values that exist as an effective mechanism for creating value in the form of society, economy and environment. The development of social enterprise is considered to have contributed in increasing innovation as well as being a mechanism for ensuring economic development that is in line with social justice. However, the development of theory and study of social enterprise is still lagging behind in practice. The social enterprise conception is a conception that is still considered as a "young term" category in the social sciences and has not shown clear consistency linking social theories to the development of social enterprise. This study aims to identify the basic theories of social enterprise and social theories for social enterprise with used an integrated literature review approach with data sources from Scopus and ProQuest. The results of the study found that socio-economic theory is the basis for social enterprise theory. This study also found the linkages of 7 social theories for social enterprise and the mapping of social theory architecture for social enterprise which is studied on classical and contemporary social theories.
