Judul: Kontrol Hormonal Pada Implantasi
Abstrak: Terjaninya implantasi diinduksi oleh kerja dari hormon progesteron, estrogen dan kemungkinan besar juga histamin dan prostaglandin. Sekresi progesteron dan estrogen adalah hasil rangsangan LH (Luteinizing Hormon ) dan LTH (Luteotropik Hormon ) atau prolaktin, jadi LH dan LTH te~ libat tidak langsung dalam peristiwa implantasi. Sebelum terjadinya implantasi estrogen menginduksi uterus untuk persiapan penerimaan blostosis pada implantasi, dalam proses induksi tersebut dibantu pula oleh progesteron.

Judul: Peranan hormon dan induksi ovulasi pada unggas
Abstrak: Hormon ovarium yang berperan dalam pengaturan sekresi gonadotropin dan siklus ovulasi adalah hormon Progesteron dan Estrogen. Kedua hormon itu secara menyolok meningkat dalam plasma darah menjelang ovulasi, kemudian turun ke keadaan normal pada saat ovulasi, kecuali estrogen yang masih tampak tinggi beberapa jam setelah ovulasi. Progesteron yang meninggi sebelum ovulasi tersebut merangsang hipotalamus yang selanjutnya mempengaruhi hipofisa untuk menghasilkan hormon-hormon gonadotropin yang penting dalam pembentukan telur dan ovulasi. Jadi dalam hal ini progesteron memberikan effek positif feedback terhadap pelepasan hormon gonadotropin. Estrogen juga dihasilkan di ovarium, dan konsentrasi- nya meningkat menjelang ovulasi sampai beberapa jam setelah ovulasi. Estrogen bersama progesteron mempunyai effek positif feedback terhadap pelepasan hormon gonadotropin men- jelang ovulasi, tetapi jika hanya estrogen effek positif feedback tidak terjadi. ...

Judul: Development of Cassava-Based Value-Added Product According to Vanuatu Circumstances
Abstrak: Cassava (Manihotesculantacrantz) in most developing countries such as in South America, Africa and South East Asia is becoming popular in its potential of value added products.Due to its rapidly deterioration within 40-48 hours after harvest, manufactures prefer to convert cassava tubers into more stable forms such as chips and flours so as to prolong the shelf life of the product.Cassava chips and flours are produced as value added products, found great use in food formulation activities in proceed food industries. More recently, the food crop is an important crop for various value added products in bakery, pastry and confectionary industries. In Indonesia, the crop remains first and foremost a food crop used in great variety of dishes. In the outer district of TrenggalekRegency in East Java Province, the root crop has been an alternative income besides other commodities. The region has been involved in various developments on cassava value added product. One of these developments is the production of modified cassava flour(mocaf). Mocaf has recently been introduced as one way of improving the characteristics of cassava flour through fermentation principles of lactic acid.This new product is no inferior to wheat flour and has high potential to substitute wheat flour in most of its applications. On the other hand, in Vanuatu where cassava is one of the stable food, have lack the knowledge to benefit from this common root crop. Since the driving force to be able to benefit from cassava has never been ceased, this research was well designed to fill this gap of development in Vanuatu as a means to provide alternative income besides copra, cocoa, kava and cattle. The research is intended to study the whole process of developing cassava value added products from farm to table.Lesson learned from the research will be appllied according to Vanautu circumstances. Thus, there is no better lesson learned and knowledge gained than to start with the six principles of supply chain management as an approach to identify the three selected management style in the outer districts of Trenggalek region. These management style includes famer, cluster and cooperation. The method used were direct participatory (observation, practise, interview and discussion) along with Supply Chain Management(SCM) approach as means to study their efficiency and profitability along the supply chain. The research performed SWOT analysis on the overall operation of the management style based on SCM approach. Hence, it is concluded that best potential management style development towards cassava value added product according to Vanuatu circumstance would be the farmer and cooperation management style. The two management style execute good mutual relationship and creative logistics as far as SCM concept is concerned. With that value, it is believedit would reduce difficulties and constraints in Vanuatu circumstances where finance and lack of government policies are still very uncertain. As such, appropriate strategies were developed from the lesson learned and integrated into Vanuatu circumstances.The strategies in reducing market risks by working towards interdependency among supply chain members, Cooperating to learn how to create value together and then collaborating to consistently utilise the new value as a source of competitive
