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: Perbandingan Ukuran dan Bentuk Morfometrik Permukaan Kepala Beberapa Domba Lokal Indonesia
Abstrak: The aim of this research was to compare the head size and shape of thin-tailed sheep (domba ekor tipis or DET), batur, wonosobo, and garut sheep (fighting and meat types). The variables measured were akrokranion-prosthion (X1), basion-prosthion (X2), mandibular (X3), head height (X4), facial tuber (X5), nasion-rhinion (X6), entorbitale (X7), euryon (X8), supraorbitale (X9). There were 111 heads of local sheep that used in research (32 rams and 79 ewes). Data were analyzed by descriptive statistics, T2-Hotelling and principal component analysis. Differences of head size surface among breeds were found in this experiment. The head size discrimination of the DET and garut meat type was basion-prosthion, since the eigen vektors are +0912 and +0928, respectively. The head size discrimination of the batur and wonosobo sheep was akrokranion-prosthion that their eigen vektors are +0969 and +0902 respectively. The head shape discrimination of DET, wonosobo and garut meat type were mandibular which those eigen vektors are +0904, +0836, and +0965 respectively. The head shape discrimination of Batur sheep was head height with the value of eigen vektor is +0907. The head size and shape discriminations on garut fighting type sheep was head hight with eigen vektor values are +0905 and -0406. Data clustered between garut fighting and meat types was separated. It also happened between batur sheep and wonosobo sheep. Overlaping data was found on DET, garut fighting-type, wonosobo and batur sheep.

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%.
