Judul: Pendugaan Parameter Genetik dan Kualitas Buah Pepaya Hibrida
Abstrak: This study aims to obtain a hybrid papaya varieties that have a high heterosis value to be released into new varieties. The research was conducted in May 2011 to May 2012 at Research Station PKHT IPB Tajur (250 m asl) and at post-harvest laboratory PKHT Baranang Siang, Bogor, West Java. This study used six genotypes consist of 3 hybrid genotypes IPB H93, IPB H91, IPB H39 and parent genotypes IPB 9, IPB 3 and IPB 1. Quantitative parameters were observed that plant height; first fruit position; amount of fruit, flower and leaves per plant; stem diameter; fruit diameter, fruit length and circumference of fruit; whole fruit weight, edible portion, 100 seed weight, and the whole seed weight; the skin and flesh firmness; flesh thickness; total soluble solid (obrix); juice pH; total tritated acid; vitamin C. Qualitative parameters were observed that fruit skin color, flesh color of ripe fruit, fruit shape, and the dominant central cavity. The result showed that hybrid genotype IPB H91 had a lot of character superior to the other between hybrids genotypes and had the better character than the parents.

Judul: Karakterisasi Morfologi Bunga, Buah dan Kualitas Buah Tiga Genotipe Pepaya Hibrida
Abstrak: This research was conducted from January-June 2012 at Teaching Farm Tajur and Postharvest Laboratory Baranang Siang, PKHT-IPB-Bogor. The objective of this research was to study the morphological characters of flowers, fruit, and fruit quality of three genotypes of hybrid papaya IPB H91, IPB H93, and IPB H39. The parameters were the qualitative and quantitative character of flowers and fruit, physical and chemical quality of fruit and organoleptic test. The result of the research showed that three genotypes of hybrid papaya had different superior characters. IPB H91 had long flower stalks, a high flower number per stem and fruits, high fruit flesh weight, edible portion, and flesh thickness, hard flesh firmness, and low total titrated acid. IPB H93 had many high flower number, low seed number per fruits and high total soluble solid. IPB H39 had short distance between the segment, hard fruit peel firmness and high vitamin C content. Organoleptic test showed that IPB H39 had shape and taste more preferred by panelist. IPB H91 can be alternative to get hybrid papaya because had more superior characters at generative phase than other genotype

Judul: Urolitiasis pada anjing
Abstrak: Urolitiasis adalah suatu penyakit dimana terjadi proses pengendapan batu pada traktus urinaria. Kalkuli yang paling banyak dijumpai pada kasus urolitiasis anjing adalah kalkuli magnesium amonium fosfat (struvite), jika dibandingkan dengan kalkuli oksalat, sistin dan urat (Osborne et al., 1982). Infeksi oleh Staphylococcus aureus pada traktus urinaria memgang peranan penting dalam proses pembentukan kalkuli, karena bakteri tersebut dapat menghasilkan enzim urease, raktor predisposisi tidak dapat dinisankan dari infeksi traktus urinaria. Pada anjing, tempat yang banyak didapati pengandapan kalkuli adalah kantung air kemih dan uretra, sedangkan pada ginjalnya jarang. Pada anjing jantan lebih sering kejadiannya dibanding dengan pada anjing betina, karena anatomi traktus urinaria pada anjing jantan lebih memungkinkan untuk terjadinya obstruksi, yaitu lebih panjang dan sempit. Besarnya, kalkuli bervariasi, dari kecil dan halus seperti pasir sampai besar dan kasar seperti batu karang. ...
