Judul: Pembuatan Ravioli Sari Jeruk Medan dengan Teknik Spherification
Abstrak: Ravioli is a innovative food product which created by spherification technique involved adding a small quantity of natrium alginate into a fruit juice and carefully spooning this liquid into a solution consisting of water and calcium chloride. The fruit juice came in contact with the calcium chloride solution created a sphere. In increase the popularityof medan citrus, it has a great potential to become processing the citrus into fruit ravioli. The objectives of this research were to find the best formulation of natrium alginate (0.6, 0.7, and 0.8%), calcium chloride (0.6 and 0.7%), and glucose solution (15 and 22.5 obrix) for producing citrus ravioli, and to analyze the characteristics of medan citrus ravioli produced in this experiment.The best formulation based on consumer hedonic test was 0.8% natrium alginate, 0.7% calcium chloride, and 15 obrix glucose solution. In this formulation, medan citrus ravioli has 112 mg/100 gr citrus ravioli total acid, 6.56% total glucose, 48.4 mg/100 gr citrus ravioli Vitamin C, and total suspended solids 1033.33 mg/l. Analysis of cost production based on 1 kg medan orange is Rp 86,079.42, if the price of medan citrus ravioli is Rp 7,000.00/cup then the profit become Rp 25,920.58.

Judul: Aplikasi Teknik Spherification dalam Pembuatan Ravioli Semangka Merah (Citrullus vulgaris Schard)
Abstrak: Watermelon is rich in nutrients and only have little derived products. A new derivate product from watermelon is ravioli. This product can be developed by spherification technique. Spherification is the culinary process that a liquid is thickened with sodium alginate and submerged in a bath of calcium chloride to create spheres and encapsulate the liquid. So, the texture of fruit ravioli is very unique, juicy inside and semi solids outside. This research was aimeds (i) to get the best process condition of producing watermelon ravioli by spherification techniques, (ii) to know the characteristics of the ravioli product, and (iii) to get the best formula. The best product based on the characterization and consumer preference was ravioli that produced from 0.4% of sodium alginat, 0.5% of CaCl2 and 10oBrix glucose solution. The product has 858.33 mg/l suspended solids, 40.00 mg citric acid/100 g ravioli, 20.53 mg ascorbic acid/100 g ravioli, and 6.29% sugar. It was also good aroma, mouthfeel, and also could suppress the rate of ascorbic acid degradation.

Abstrak: Penyakit tuberkulosis pada satwa primata disebabkan oleh bakteri Mycobacterium yaitu Mycobacterium tuberculosis, Mycobacterium bovis, dan Mycobacterium avium, yang masing-masing menyebabkan tuberkulosis tipe human, bovin dan avian. Dari ketiga tipe tersebut, tuberkulosis tipe human adalah yang paling banyak ditemukan pada satwa primata. Ketiga tipe ini dapat dibedakan dengan melihat sifat-sifat bakteri pada pupukan dan virulensinya pada beberapa hewan percobaan. Kepekaan beberapa golongan satwa primata terhadap tuberkulosis berbeda satu dengan lainnya. Tuberkulosis tipe human dapat mengakibatkan kasus penyakit yang sangat fatal pada grup "Old World Monkey ", sedangkan "New World Monkey " tampak lebih resisten dan grup Prosimian jarang terkena tuberkulosis. Kasus tuberkulosis belum pernah ditemui pada koloni satwa primata yang hidup di hutan dan jauh dari pemukiman manusia. Tampaknya penularan yang terjadi pada satwa primata didapatkan dari kontak dengan manusia. Penularan tuberkulosis ini terutama adalah melalui inhalasi, kontak langsung, infeksi silang dari hewan-hewan jenis lain, juga dari peralatan yang terkontaminasi misalkan termometer rektal, tatoo, masker pembius dan tempat makanan. ..
