Judul: Ukuran dan Bentuk Tubuh pada Domba Ekor Tipis, Domba Batur, Domba Wonosobo dan Domba Garut
Abstrak: Sheep potentially large as producing meat and wool for the public need the world. The research aimed to obtain genetic information morphometric characteristics based on size and shape body of Thin-tailed sheep (DET), Batur sheep (Dombat), Wonosobo sheep (Dombos), and Garut sheep (Fighting-type and Meat-production-type) that aged 1.5-2.0 years. Data obtained by measuring the linear body measurements sheep and processed with descriptive statistics, statistical T2-hotelling and principal component analysis. Result showed that body surface linear measurements were significantly different (P<0.01) between breeds. Principal component analysis resulted shoulder height was the size discriminator on DET, Dombat, Dombos, Fighting-type Garut and Meat-producing-type Garut sheep. Hip height was the size discriminator on DET, Fighting-type Garut and Meat-producing-type Garut sheep. Body length was the size discriminator on Dombat and Dombos. Shoulder height is a form discriminator on DET and Fighting-type Garut sheep. Body length is the shape discriminator on Dombat, Dombos and Meat-producing-type Garut sheep. Hip height is a form discriminator in Dombos while chest wid this a form discriminator in Meat-producing-type Garut sheep. Group diagram showed that the individual data for each sheep was unique because it formedits own group. Data group all sheep intersecting against DET, this shows that all sheep research had blood DET as their elders.

Judul: Analisis Diskriminan Ukuran Tubuh Betina pada Domba Ekor Tipis Batur Wonosobo dan Garut
Abstrak: The purpose of this research was to evaluated the differences among morphometric characteristics of Thin-Tailed, Batur, Wonosobo and Garut (fighting and meat types) ewes. Variables be observed were shoulder height, hip height, body lenght, chest width, chest depth, hip width, rump width, rump length, metatarsus length, metacarpus length and cannon circumference. Number of sheep be observed were 79 heads. The data was analyzed with T2-Hotelling test, fisher discriminan analysis, Wald-anderson and D2-Mahalanobis minimum distance. Discriminator variable between Batur vs Garut meat type was cannon circumference, Batur vs Garut fighting type was shoulder height and cannon circumference, Batur vs Wonosobo was hip width, Thin-Tail vs Batur was body length, Thin-Tailed vs Garut meat type was shoulder height, Thin-Tailed vs Garut fighting type was shoulder height, Thin-Tailed vs Wonosobo was body length, chest width, hip width, rump width , rump length, Wonosobo vs Garut meat type was hip width. Unsimilarity distance between Batur and Garut meat ewes, type was 4.058, Batur and Garut fighting type was 2.278, Thin-Tailed and Batur was 3.950, Thin-Tailed and Garut meat type was 2.758, Thin-Tailed and Garut fighting type was 2.921, Thin-Tailed and Wonosobo was 4.748, Wonosobo and Garut meat type was 2.204. Thin-Tailed was separated from the others. Wonosobo formed a group together with Garut. Garut fighting and meat types was not separated because it was a group of Garut Sheep. Garut and Wonosobo formed one group that separated from Batur.

Judul: Katalis Zink Ferit Tersubstitusi Cu untuk Oksidasi Benzil Alkohol
Abstrak: Katalis berperan dalam menurunkan energi aktivasi. Katalis ZnFe2O4 dan ZnFe2O4 tersubstitusi Cu disintesis menggunakan metode kopresipitasi untuk digunakan dalam oksidasi benzil alkohol. Katalis dicirikan dengan spektrofotometer inframerah (FTIR) dan difraktometer sinar-X. Spektrum FTIR menunjukkan puncak serapan dari ikatan Zn-O dan Fe-O masing-masing pada rentang 559‒575 cm-1 dan 419‒447 cm-1. Difraktogram menunjukkan terbentuknya fase tunggal Zn0.6Cu0.4Fe2O4 pada katalis ZnFe2O4 tersubstitusi Cu 20%. Benzil alkohol dioksidasi dengan sistem refluks. Konversi benzil alkohol meningkat dengan meningkatnya suhu. Kadar benzaldehida yang dihasilkan dengan katalis ZnFe2O4 tersubstitusi Cu 20% lebih tinggi dibandingkan dengan katalis ZnFe2O4 yang tidak tersubstitusi dan yang tersubstitusi Cu 60 dan 80%. Hal tersebut menunjukkan bahwa katalis ZnFe2O4 tersubstitusi Cu 20% memiliki kinerja yang lebih baik dalam oksidasi benzil alkohol menjadi benzaldehida dengan kadar benzaldehida 8.763%.
