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: 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: Sintesis Flavonol melalui 2’-Hidroksikalkon
Abstrak: Flavonol is a class of flavonoids commonly found in fruits and vegetables. Flavonol is very useful, especially in food sector and health. In this study, flavonol unsubstituted was successfully synthesized from an intermediate material 2’-hydroxychalcone. The 2’-hydroxychalcone was synthesized by Claisen-Schmidt condensation method between o-hydroxyacetophenone and benzaldehyde using 4 different catalysts, namely KOH 60%, solid pellet of KOH-grinding technique, BF3-Et2O, and NaH in DMF. The KOH 60% was the best catalyst, giving the highest yield (57%). Afterward, the flavonol was synthesized in 1-stage oxidation cyclization of o-hydroxyacetophenone using Algar-Flynn-Oyamada (AFO) reaction, giving 76%. The flavonol total yield from 2’-hydroxychalcone was 43%. All synthesized products were characterized by their melting points and their spectra. The success of the synthesis flavonol opens the way to synthesis of useful flavonol derivatives such as quercetin and kaempferol
