Judul: Pencegahan Infeksi Aeromonas hydrophila pada Ikan Nila dengan Tepung Buah Mengkudu (Morinda citrifolia) melalui Pakan
Abstrak: Ikan nila merupakan komoditas air tawar yang dapat terserang penyakit MAS (Motile Aeromonas Septicemia) yang disebabkan oleh bakteri Aeromonas hydrophila. Buah mengkudu berpotensi untuk dimanfaatkan sebagai upaya pencegahan karena mengandung senyawa aktif seperti scopoletin, antrakuinon, fenol, flavonoid, dan alkaloid. Penelitian ini bertujuan untuk menentukan dosis tepung buah mengkudu (Morinda citrifolia) dalam pakan sebagai upaya pencegahan infeksi bakteri A. hydrophila pada benih ikan nila. Ikan nila yang digunakan memiliki bobot awal 12,75 ± 0,31 g yang dipelihara selama 30 hari dengan perlakuan pemberian pakan kemudian diuji tantang pada hari ke-31, dan dipelihara kembali selama 14 hari dengan pakan komersil. Perlakuan yang digunakan berupa penambahan tepung buah mengkudu dengan dosis 5 g/kg pakan (D5), 10 g/kg pakan (D10), 15 g/kg pakan (D15), kontrol positif (K+), dan kontrol negatif (K-). Penambahan tepung buah mengkudu menunjukan hasil kelangsungan hidup, total leukosit, gejala klinis dan kondisi organ dalam yang lebih baik dibandingkan kontrol positif. Tepung buah mengkudu yang diberikan melalui pakan kepada ikan nila dapat mencegah infeksi bakteri A. hydrophila dengan dosis terbaik pada dosis 10 g/kg pakan., Tilapia is a freshwater commodity that can be attacked by MAS (Motile Aeromonas Septicemia) caused by Aeromonas hydrophila bacteria. Noni fruit has the potential to be used as a preventive measure because it contains active compounds such as scopoletin, anthraquinones, phenols, flavonoids, and alkaloids. This study aims to determine the dose of noni fruit flour (Morinda citrifolia) in feed as an effort to prevent infection with A. hydrophila bacteria in tilapia fry. The tilapia used had an initial weight of 12.75 ± 0.31 g which were reared for 30 days by feeding treatment, then challenged on the 31st day, and reared again for 14 days with commercial feed. The treatments used were the addition of noni fruit flour at a dose of 5 g/kg feed (D5), 10 g/kg feed (D10), 15 g/kg feed (D15), positive control (K+), and negative control (K-). The addition of noni powder showed better survival results, total leukocytes, clinical symptoms and organ conditions compared to positive controls. Noni fruit flour given through feed to tilapia can prevent infection with A. hydrophila bacteria with the best dose at a dose of 10 g/kg feed.

Judul: Prevention of Motile Aeromonad Septicemia in Tilapia  Larvae with Ambon Banana Stem Extract
Abstrak: Produksi ikan nila dapat ditingkatkan dengan mencegah kematian ikan pada fase larva. Fase larva pada ikan adalah fase yang rentan terserang penyakit, salah satunya Motile Aeromonad Septicaemia (MAS) yang diinfeksi oleh Aeromonas hydrophila. Salah satu cara untuk mencegah MAS adalah dengan perendaman menggunakan ekstrak seduh batang pisang ambon. Penelitian ini bertujuan untuk menentukan dosis optimum perendaman larva ikan nila dengan ekstrak seduh batang pisang ambon untuk pencegahan infeksi A. hydrophila. Bahan uji yang digunakan adalah larva ikan nila, batang pisang ambon dan bakteri A. hydrophila. Penelitian terdiri dari perlakuan K+ (tanpa perendaman dengan ekstrak seduh batang pisang ambon dan diuji tantang dengan A. hydrophila), dosis perendaman ekstrak seduh batang pisang ambon (0,1% (v/v), 0,25%(v/v) dan 0,5%(v/v)) selama 30 menit. Pemeliharaan larva dilakukan selama 14 hari dan diuji tantang pada hari ke-8 dengan kepadatanbakteri 104 CFU/mL (LC50) sebanyak 1 mL/60 ekor dan direndam selama satu jam kemudian dipindahkan ke wadah pemeliharaan. Perendaman dengan ekstrak seduh batang pisang ambon dapat meningkatkan sintasan pada larva ikan nila yang diuji tantang dengan A. hydrophila. Dosis perendaman ekstrak batang pisang ambon pada larva ikan nila adalah 0,25% dan 0,5% dengan sintasan sebesar 90,01±1,81% dan nilai RPS sebesar 84,54% yang didukung dengan parameter respon imun berupa aktivitas lisozim. Kata kunci: Aeromonas hydrophila, batang pisang, ikan nila, sintasan, Tilapia production can be increased by preventing fish mortality in the larval stage. The larval phase in fish is a phase that is susceptible to disease, one of which is Motile Aeromonad Septicaemia (MAS) which is infected by Aeromonas hydrophila. One way to prevent MAS is by soaking using the extract of the brewed banana stem of Ambon. This study aims to determine the optimum dose of immersion of tilapia larvae with ambon banana stem extract to prevent A. hydrophila infection. The test materials used were tilapia larvae, Ambon banana stem and A. hydrophila bacteria. The study consisted of K + treatment (without immersion in the extract of ambon banana stem and challenged with A. hydrophila), immersion dose of ambon banana stem extract (0.1%(v/v), 0.25%(v/v) and 0.5%(v/v)) for 30 minutes. Larva rearing was carried out for 14 days and tested on the 8th day with a bacterial density of 104 CFU / mL (LC50) of 1 mL / 60 and soaked for one hour then transferred to a rearing container. Soaking with the extract of ambon banana stem brewed can increase survival in tilapia larvae that were challenged with A. hydrophila. The immersion dose for Ambon banana stem extract in tilapia larvae is 0.25% and 0.5% with a survival rate of 90.01 ± 1.81% and an RPS value of 84.54% which is supported by immune response parameters in the form of lysozyme activity.

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.
