Judul: Variasi genetik Scirpophaga incertulas (Walker) berdasarkan gen cytochrome oxidase 2
Abstrak: Scirpophaga incertulas (penggerek batang padi kuning) merupakan hama utama padi yang menjadikan padi sebagai inang satu-satunya serangga ini. Spesies tersebut pada saat fase larva merusak tanaman padi dengan menggerek bagian pelepah daun dan batang. Dalam upaya pengendalian hama utama padi tersebut, analisis berdasarkan suatu gen dapat digunakan sebagai monitoring untuk memantau suatu populasi suatu organisme. Belum adanya data genetik S. incertulas pada daerah gen cytochrome oxidase 2 (cox2) di Indonesia maka penelitian ini bertujuan untuk mempelajari variasi genetik S. incertulas berdasarkan gen cox2 dengan metode sekuens DNA. Eksplorasi S. incertulas dilakukan di daerah Bogor dan areal persawahan pantai utara Jawa Barat: Karawang, Indramayu dan Cirebon. Variasi genetik S. incertulas berdasarkan gen cox2 ditemukan sebanyak empat haplotipe. Haplotipe 1 merupakan haplotipe umum yang ditemukan dibanyak sampel dari keempat daerah yang dieksplorasi (Bogor, Karawang, dan Indramayu). Haplotipe 2, 3 dan 4 berturut-turut ditemukan pada S. incertulas populasi Bogor (Sc11Bg), Karawang (Sc24Kr) dan Cirebon (Sc1Cb). Haplotipe 2 dicirikan dengan adanya nukleotida A pada posisi nukleotida ke-162. Haplotipe 3 dicirikan dengan adanya nukleotida G pada posisi ke-51 dan haplotipe 4 dicirikan dengan adanya nukleotida C pada posisi nukleotida ke- 63. Variasi yang terjadi antar individu dalam satu populasi hanya terjadi di daerah Bogor dan Karawang. ABSTRACT

Judul: Haplotype Variations of Yellow Rice Stem Borer Scirpophaga incertulas Based on Cytochrome c Oxidase 1 and 2 (COI and COII) Mitochondria Genes.
Abstrak: Scirpophaga incertulas or yellow rice stem borer (Lepidoptera: Crambidae) is one of the main insects caused damage yields in rice in Asia, including Indonesia. In the first instar of S. incertulas larva, the moth cannot be discriminated with other species of rice stem borers. Hence, a molecular approach is needed for early detection purpose. Previous study found six haplotypes of cytochrome oxidase 1 (COI) of S. incertulas from Java and four haplotypes of cytochrome oxidase 2 COII gene in S. incertulas from West Java. The objective of this research was to explore further the haplotype variations of the S. incertulas of COI and COII genes in Central Java, Special Region of Yogyakarta (DIY), East Java, and Bali, to fulfill the haplotypes variation data in Indonesia. The study found three new haplotypes (haplotype 7, 8, and 9) of S. incertulas COI sequences as well as three new haplotypes (haplotype 5, 6, and 7) of COII sequences. Those new haplotypes of S. incertulas COI gene were found in Lumajang, Sleman, and Pemalang regions. DNA alignment analyzes result based on S. incertulas COII gene revealed three new haplotypes i.e. haplotype 5 in Mojokerto, Tabanan, Lumajang, Pemalang, Klaten, Jember, and Kebumen region, haplotype 6 in Probolinggo regions, and haplotype 7 in Situbondo region. Nucleotide variations of moth S. incertulas COII were higher compare to COI gene. Database of COI and COII haplotype variations of yellow rice stem borer can be used as markers to differentiate S. incertulas with other species of rice stem borers during the first larva instar for their early detection. Phylogenetic analysis of S. incertulas COII revealed three clusters in Java and Bali.

Judul: Pengembangan distribusi ILOS multimedia (ILOSmedia)
Abstrak: The development of open source softwares is still going rapidly nowadays, including open source operating systems for desktop computer, netbook, tablet PC, and smartphone. The open source operating systems have considerable contribution to open source software. Linux is an open source operating system that continues to grow since 1991. The characteristics in general Linux are free, can be distributed freely, and free to make changes in it. Linux in its development is divided into several distributions. Each distribution is made as a specific goal so that the operating system can focus on running the desired functions, such as multimedia, networking, education, etc. The objective of of this research is to develop and evaluate the ILOS distribution for multimedia by providing multimedia of open source packages. ILOSmedia uses Ubuntu10.10 and Remastersys as a tool to remaster. ILOSmedia is developed by installing multimedia packages that have been obtained based on the results of questionnaires from 30 respondents from three communities, which are KPLI Bogor, Linux.com forums, and Kaskus.us forums. ILOSmedia also uses the Realtime kernel as kernal Mutimedia. ILOSmedia testing is performed by 11 students of Computer Science who are members of FOKERZ community. The testing process is performed by executing ILOSmedia via live-cd and filled in a questionnaire. The test result shows that ILOSmedia has hardware compatibility on notebook and PC with good performance. As much as 72.727% of respondents believe that the size of the installer ILOSmedia of 1.34 GB and a minimum 10GB hard drive is normal. ILOSmedia has multimedia packages complete with the percentage completeness according to respondents is 45.455% are very complete and 54.545% are complete. Boot speed ILOSmedia have an average of 28.87 seconds and 90.91% of respondents consider that ILOSmedia have a desktop environment that is easy navigation
