Judul: Penggunaan Naungan yang Berbeda pada Pendederan Benih Ikan Lele di Bak Terpal
Abstrak: Catfish fry rearing is usually done in the pond of land in open space. Fish fry mortality because of high fluctuations in water quality to be very high, especially in the rainy season. Shade usage on fish rearing was expected to reduce the changes of water quality parameters from heat and rain. This research uses terpaulin container with a (300X400X50) cm dimension, each were given shades from different materials as given, transparent plastic (treatment 1), shading net (treatment 2), and dark plastic (treatment 3), while control container were not given any shade. This research resulted in a very low survival rate 13.82±8,77% on treatment 1, 1.08±1,87% on treatment 2, 0.12±0,2% on treatment 3, and 13.65±4,17% on control. Highest weight daily growth rate were acquired by treatment 1, namely 1,094±0,0186%, and the lowest were in control fish 1,079±0,0096%. Highest increase the absolute length were acquired by treatment 1, namely 3,53±0,602 cm, and the lowest were in control fish 2,79±0,185 cm. Based on variance analysis, the usage of shades on catfish rearing did not gave a significant effect on increase the absolute length and weight daily growth rate (p>0,05), but it affects the survival rate significantly (p<0,05). The usage of transparent plastic is suggested for catfish fry rearing in tarpaulin container.

Judul: Pengaruh Padat Penebaran Dengan Ukuran Yang Berbeda Pada Sistem Pendederan Terhadap Kinerja Pertumbuhan Benih Ikan Lele Clarias
Abstrak: Penelitian ini bertujuan untuk mengevaluasi pemeliharaan ikan lele pada pendederan I dengan kepadatan dan ukuran tebar berbeda terhadap pertumbuhan dan efisiensi pakan. Benih ikan lele umur 10 hari dikelompokkan terlebih dahulu menjadi dua ukuran berbeda M (1,6-1,9 cm) dan S (1,4-1,5 cm). Benih tersebut dipelihara dalam bak terpal ukuran 6x3x0,5 meter dengan ketinggian media hingga 40 cm. Ikan dipelihara selama 13 hari dengan padat tebar 1000 e/m2 dan 2000 e/m2 dengan dua ukuran tebar bebeda. Pemberian pakan dilakukan secara at satiation. Jenis pakan yang diberikan yaitu fengli dan PF 500. Pakan diberikan pada pukul 06.00, 16.00 dan 22.00 WIB. Hasil penelitian menunjukkan bahwa ikan yang ditebar dengan ukuran M (besar) dengan kepadatan 1000 e/m2 memiliki pertumbuhan dan efisiensi pakan yang lebih baik yang dicirikan dengan komposisi ukuran panen mayoritas ukuran L (67,6 %) di akhir masa pemeliharaan.

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.
