Judul: Perubahan Warna Ikan Maskoki Carassius auratus yang Diberi Pakan Berkarotenoid dengan Lama Pemberian Berbeda
Abstrak: Goldfish or “maskoki” is a beautiful freshwater ornamental fish. Price of goldfish depends on several factors, one of them is the body color. The body color of goldfish depends on carotenoid contain on its feed. Carotenoid source must be added into the goldfish feed that used for intensive rearing. Unfortunately, the price of commercial feed that contain carotenoid such as spirulina, relatively more expensive than common commercial feed. So, it require a combination between common commercial feed and those which contain spirulina to lower the cost. Uniformed orange fish seeds, average body length 3.2 ± 0.28 cm and average weight 4.9 ± 0.9 gram fed common commercial feed and feed that contain spirulina as carotenoid source. Fish were fed three times a day with feeding rate 5% of its biomass on first 20 days of rearing and 4% on the next 20 days. Ratio feeding period of common feed : carotenoid feed in this research was: 1) 40:0 (fed common feed for 40 days and carotenoid feed for next 0 days), 2) 30:10, 3) 20:20, 4) 0:40. Percentage of color score evaluation was the total number of fish based on color criteria divided by total number of living fish times 100%. Color changing of goldfish that happened on application of feeding period with carotenoid feed for 40 days was orange-red as much as 93.10% and those which did not change orange color was 6.90%. Color changing that happened on application of feeding period with carotenoid feed for 20 days was orange-red as much as 58.33% and yellow-orange was 2.78% and those which did not change orange color was 38.89%. Color changing that happened on application of feeding period with carotenoid feed for 10 days was orange-red as many as 55% and faded 5% and those which did not change orange color was 40%. Color changing that happened on application of feeding period with carotenoid feed for 0 days was yellow-orange as many as 36.11% and faded 5.56% and those which did not change orange color was 58.33%. Carotenoid feed did not effect to weight and length growth rate and length differentiation coefficient. The best period of carotenoid feed for goldfish is 10 days that resulted color change to orange-red was 55% and best of R/C ratio.

Judul: Rematuration of Goldfish Carassius auratus with the addition of Red Fruit Oil Pandanus conoideus through Feed.
Abstrak: Buah merah Pandanus Conoideus merupakan salah satu tanaman endemik Papua yang mengandung makro dan mikro nutrien, salah satu diantaranya adalah Vitamin E (tokoferol ) sebesar 11.000 mg/l dalam 100 g. Vitamin E merupakan mikro nutrien yang dibutuhkan dalam masa reproduksi ikan yaitu berperan dalam pembelahan sel. Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan minyak buah merah melalui pakan terhadap rematurasi ikan mas koki. Penelitian ini dilakukan selama 28 hari dengan perlakuan pemberian dosis minyak buah merah (MBM) dan Kontrol (A) yaitu pakan tanpa MBM. Perlakuan MBM terdiri dari dosis MBM 175 mg/kg pakan (B), MBM 375 mg/kg pakan (C), MBM 500 mg/kg pakan (D). Hasil penelitian menunjukkan bahwa pemberian MBM melalui pakan menghasilkan nilai kebuntingan pada hari ke- 15, dengan hasil terbaik yaitu perlakuan MBM 500 mg/kg dengan presentase 66,67%, pergerakan inti telur (GVBD) 80% mulai hari ke-21, tingkat ovulasi 37%.

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.
