Judul: Genetic Diversity and Identification of Specific Production Character Markers of Oil Palm Progeny and Parent with SSR Marker
Abstrak: This thesis studies the relationship between microsatellite markers with the character of the production of oil palm (Elaeis guineensis Jacq.) in an attempt to get specific markers that can be useful in the parental selection. The first experiment was carried out by observing the genetic diversity of 80 progeny palm oil that has been classified by the character of high and and low production. Each of these 20 individuals were observed for the characters of oil to bunch (OB), bunch number (BN), oil yield (OY) and fresh fruit bunches (FFB). The results showed a fairly high genetic diversity of the four characters, which is shown by the quite high average percentage of polymorphic and PIC, ie 52.78% and 0.51. Construction of dendogram based on UPGMA can distinguish the characters from one to another by the percentage of genetic similarity 56-100% or ~44% of genetic diversity. The separation of the characters into the four groups was also confirmed using PCoA (Principle Coordinate Analysis). It also found the specific markers for the characters observed, ie one marker specific to the character of OB, four markers specific to the character of BN, one marker specific to the character of OY and two marker specific to the character of FFB. The second experiment was conducted to identify specific markers of the four characters. Correlation and stepwise regression approach used in this experiment. The results showed that there are 11 specific markers were obtained using the correlation approach, as well as 16 specific markers obtained using stepwise regression approach. From the results it is known that one marker positively correlated and regressed to the OB, two markers positively correlated and regressed to the BN, one marker positively regressed to OY, but only one marker that positively correlated to OY, and no one is positively correlated or regressed to FFB. The third experiment was conducted to determine the genetic diversity of Dura parents which is used as female parent in experiments 1 and 2, and its role in the diversity of the four characters tested. Two populations of Dura selfing with 30 samples per population used for analysis. The analysis showed parental separation into two groups based on the selfing. Group A, with ~20% genetic diversity, is the result of D1 selfing. While Group B, with ~28% genetic diversity is the result of D2 selfing. Both genetic material has a low genetic diversity within groups, but higher genetic diversity between group (~ 68%), as well as confirmed by PCoA and Structure. The results of t-test analysis showed that the pair D1 and D2 with a fourth character, has a significant effect on the character of the OB, OY and FFB, while the character of BN, Dura influence is not significant.

Judul: Pendugaan parameter genetik dan karakteristik molekuler
Abstrak: Since the beginning of the last century, a lot of breeding programmes have been performed to genetically improve palm oil productivity. An experiment to study heritability, general combining ability (GCA), and specific combining ability (SCA) of some traits in oil palm progeny was conducted at Kebun Surya Adi, PT. Bina Sawit Makmur, Sampoerna Agro, Ogan Komering Ilir, Sumatera Selatan, from July 2006 until September 2008. The research was arranged in alpha design with two replications, 50 progenies and 12 palms for each replication, respectively. The results showed that broad sense heritability estimates were high for kernel to h i t content ratio and B-carotene content; medium for mesocarp to hit , oil to fresh mesocarp, and bunch number; and low for fresh fruit bunch, oil to bunch and h i t to bunch ratios. The general combining ability (GCA) of bunch number, rnesocarp to b i t , oil to fresh mesocarp, and kernel to .Fruit ratios and B-carotene content were highly significant. Similarly, the specific combining ability (SCA) of mesocarp to h i t , oil to fresh mesocarp, and kernel to hit ratios and B-carotene content were also highly significant. Moreover, for genetic diversity analysis, the objectives are to

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
