Judul: Analisis Keragaman Genetik Bakteri Xanthomonas oryzae pv. oryzae dengan Teknik Amplified rDNA Restriction Analysis (ARDRA) Gen 16S-rRNA
Abstrak: Xanthomonas oryzae pv. oryzae (Xoo) causes bacterial leaf blight (BLB) of rice. Fifteen Xoo from several regions in Indonesia were analyzed their genetic diversity by using amplified rDNA restriction analysis (ARDRA) technique of 16S-rRNA gene. The aim of this analysis is to identify the genetic diversity of Xoo and can be used as a reference for HDB-resistance plant research. An amplified 16S-rRNA gene from Xoo was cut by using RsaI restriction enzyme and formed ARDRA pattern. ARDRA pattern was further used as the binary data for the construction of phylogenetics tree. Phylogenetics tree showed that the genetic relationship of the isolates was quite close. Isolate of 1/96 and 61 are close enough to 29D, 59, and 60 isolates although they are from different regions. Other isolates showed close relation are isolate 5 to 23D, 28D, 10, 8, and isolate 6 to 3 and 2 isolates. The genetic cluster quantity showed the genetic diversity of Xoo analyzed is quite high.

Judul: Asosiasi Aktivitas Selulolitik dan Analisis Molekuler dengan Metode Rep-PCR dari Xanthomonas oryzae pv. oryzae
Abstrak: Xanthomonas oryzae pv. oryzae (Xoo) causes bacterial leaf blight (BLB) of rice. Twenty seven Xoo from several regions in Indonesia were tested cellulolytic activity with CMC media, molecular analysis were analyzed using the technique of Rep-PCR, and analyzed the association between the two by using the program Tassel. The purpose of this study is to investigate the association between cellulolytic activity and molecular analysist with Rep-PCR method from Xoo DNA bacteria. The results of cellulolytic activity from 27 isolates Xoo, 7624 isolate known as type IV has the largest clear zone is 1.43 cm and Xoo12-253 isolate has the smallest clear zone is 0.31 cm. For the molecular characteristics, used BOXA1R, (GTG)5, and ERIC primers to amplify genomic DNA and produces polymorphic Xoo DNA bands different between three primers. Most PIC value obtained by the ERIC primer with value 0.34. The results of testing the association of cellulolytic activity and molecular characteristics of DNA amplification by Rep-PCR were known that have a low correlation and no significant association between the two

Judul: Penetapan Harga Jaminan Polis Asuransi Jiwa dengan Premi  Tahunan dan Opsi Surrender
Abstrak: Asuransi jiwa memberikan perlindungan pada tertanggung (pemegang polis) jika mengalami risiko finansial, dengan suatu perjanjian tertanggung harus membayar premi. Premi yang sudah terkumpul pada perusahaan asuransi dapat diinvestasikan, yang salah satu tempatnya adalah di pasar bursa. Perusahaan asuransi menawarkan suatu kontrak kepada pemegang polis yang disebut dengan kontrak partisipasi. Pada kontrak partisipasi risiko finansial dan keuntungan dibagi dengan pemegang polis dan biasanya keuntungan tersebut dimasukkan ke dalam cadangan polis pada tiap akhir tahun kontrak. Hal ini berarti secara tidak langsung perusahaan asuransi menyatakan penambahan pertanggungan, sehingga mengakibatkan perubahan benefit yang diterima oleh pemegang polis. Pada kontrak partisipasi ini, pemegang polis diberikan hak untuk mengakhiri kontrak (opsi surrender). Pada kontrak partisipasi asuransi jiwa endowmen terdapat opsi bonus (bonus option) yang penghitungan besar preminya dengan pendekatan tipe Eropa dan opsi surrender (surrender option) dengan tipe Amerika.
