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: Pengujian Pertumbuhan Tiga Genotipe Pepaya Hibrida (Carica papaya L.).
Abstrak: The research aims to examine the growth and character of three genotypes of hybrid IPB 9 x IPB 1, IPB 9 x IPB 3, and IPB 3 x IPB 9 genotypes in vegetative phase. This research was conducted at The Experimental Field Station PKBT IPB, Tajur Bogor from March to September 2011. The experiment use a randomized complete block design with six genotypes of papaya treatment. The repetition was done six times, with each unit of the experiment are five representative plants. The observation of plant growth per week was perfomed on plant height and leaf number. The observation of petiole colour, trunk diameter, petiole length, leaf length, leaf width, times of the first flowers appear, and the height position of the first flower was done once at the end of the observation that was in the week when the first flower appear. The results showed that IPB 9 x IPB 1 genotype has higher average in leaf number and trunk diameter and shorter average in height position of the first flower appear than another genotypes hybrid of papaya. Genotype of IPB 9 x IPB 3 has shorter average in plant high and smaller size in leaf which not different with IPB 9 x IPB 1. The hybrid genotypes of papaya which tested have a short score of heterosis and heterobeltiosis generally. Based on the estimation value of heterosis, genotype of IPB 9 x IPB 1 can be an alternative in obtaining hybrid because it has more superior character than two other hybrids, that of them is have higher in leaf number, bigger in trunk diameter and strong trunk, and shorter in height position of the first flower than parents genotypes.

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. ...
