Judul: Karakteristik Kerenyahan Pilus dari Dua Tepung Tapioka
Abstrak: Quality of a product is one of the most important aspects to determine consumer’s acceptance. Final product quality closely related to the quality of raw materials used. Garudafood as one of the leading food and beverage companies in Indonesia, has pilus as its main snack product. Pilus is a fried round-shaped snack made from tapioca with a mixture of other spices, ready to be consumed as a snack or side dish companion. Pilus is supposed to has a crispy texture. Garudafood needs 2000 tons of tapioca for pilus production per month. However, this necessity could not be filled with a consistent quality of the material supply. Thus, characterise the tapioca used in production to determine the test parameters that can predict pilus crispness need to be done. The parameters tested are analysis of starch level, amylose, amylopectin, swelling power, starch gelatinization profiles, texture analyzer, and organoleptic test. Moreover, the test be repeated at each arrival tapioca to see the consistency of raw materials quality. The research showed that most relevant tests to specify pilus crispness are the ratio of amylose amylopectin and peak viscosity on starch gelatinization profiles. In addition, the data indicates that the quality of raw materials used are not consistent.

Abstrak: Tapioca produced by means of modern method is not suitable for making of pilus. Pilus which is produced by using the so called “modern tapioca” will have a hard texture and not fluffy. Traditional tapioca flour is made with a long time to get a distinctive taste. However, traditional process of tapioca production could not be applied in large production scale. Therefore, experiments were conducted to produce tapioca starch of industrial scale by means of spray drying and cabinet drying process. During drying with spray dryer, three inlet temperature levels in range 140-160 °C, 170-190 °C, 200-220 °C were applied, whereas during drying with cabinet dryer, three levels of temperature in range 40-60 °C, 60-70 °C, 70-90 °C and three levels of drying time 0.75 hour, 1.5 hours, 2.5 hours were applied. The starch properties analysed were tapioca starch yield, moisture content, whiteness, fineness and gelatinization pattern of starch. The tapioca starch obtained will be applied in manufacturing of “pilus”. The characteristics of “pilus” evaluated is crispiness.

Judul: Leukemia pada kucing
Abstrak: Leukemia pada kucing adalah suatu penyakit yang sangat patogen, disebabkan oleh sejenis virus. Virus ini dikenal sebagai Feline Leukemia Virus atau FeLV. FeLV ini oleh beberapa ahli dikatakan hanya bersifat ganas pada hewan kucing. Penularannya bisa secara horizontal maupun congenital. Kucing pada semua tingkat umur dapat terserang oleh FeLV ini. Khusus pada bentuk "thymic leukemia", virus ini hanya menyerang anak-anak kucing berumur diba- wah 1 tahun. Kucing-kucing liar atau yang tidak terpeli- hara jarang sekali terinfeksi FeLV. Selain dari serangan virus FeLV itu sendiri, maka penyakit leukemia ini bisa disebabkan oleh beberapa fak- tor yang sudah ada dalam tubuh hewan dan sangat menunjang perkembangan penyakit ini, yaitu antara lain tumor, agen toksik, cedera oleh kecelakaan dan gangguan hemopoiesis. FeLV menyerang sel-sel darah dalam tubuh hewan se- hingga pembentukan darah berjalan tidak normal. Terlihat sel-sel darah yang belum dewasa sudah beredar dalam sir- kulasi darah. Bentuk dan jumlahnya tidak lagi seimbang dalam tubuh hewan kucing tersebut. Gejala klinis antara lain kekurusan, ikterus, anemia, lemah, anoreksia, dyspnoe, sulit menelan, batuk, dan membran mukosa pucat. Selain itu kelenjar pertahanan tubuh juga membengkak, kemudian terjadi hepatomegali, spleenomegali dan pembengkakan pada ginjal. Terbentuk massa tumor pada beberapa tempat. Secara biopsy pada sumsum tulang akan terlihat be- berapa perubahan. Sumsum tulang berwarna merah tua atau abu-abu. Konsistensinya lunak dan terdapat banyak sekali memproduksi sel darah putih. Melalui gambaran darah leukemia ini lebih mudah didiagnosa. Jumlah retikulosit rendah sekali. PCV 8-15%, hemoglobin menurun, sel darah putih (WBC) meningkat, lim- fosit meningkat, Alfaglobulin juga ada peningkatan, dan banyak eosinofil yang belum dewasa beredar dalam darah…dst
