Judul: Aktivitas Anti-Rayap Zat Ekstraktif Kayu Balata (Manilkara bidentata) terhadap Rayap Tanah Coptotermes curvignathus Holmgren.
Abstrak: Kayu balata (Manilkara bidentata) berasal dari famili dan genus yang telah diketahui menghasilkan berbagai senyawa dengan bioaktivitas tinggi. Penelitian ini bertujuan menentukan kadar ekstraktif kayu balata, menguji aktivitas anti-rayap ekstrak terhadap rayap Coptotermes curvignathus, dan mengidentifikasi senyawa kimia yang diduga paling berpengaruh dalam ekstrak. Serbuk kayu dimaserasi menggunakan pelarut aseton kemudian difraksinasi hingga didapatkan fraksi n-heksan, etil eter, etil asetat, dan residu. Setiap fraksi diumpankan ke rayap melalui kertas selulosa pada konsentrasi 2, 4, 6, 8, dan 10%. Identifikasi senyawa dilakukan dengan analisis GC-MS. Hasil penelitian menunjukkan kadar ekstraktif kayu balata sebesar 3.01%. Fraksi etil asetat menghasilkan aktivitas anti-rayap tertinggi yang pada konsentrasi 10% menghasilkan nilai mortalitas rayap sebesar 84% dan kehilangan berat kertas sebesar 23.2 %. Asetaldehid dan salicylic acid diduga merupakan senyawa yang paling berpengaruh terhadap aktivitas anti-rayap.

Judul: Sifat Anti Rayap Zat Ekstraktif Kayu Teras Nangka (Artocarpus heterophyllus Lamk) terhadap Serangan Rayap Tanah Coptotermes curvignathus Holmgren.
Abstrak: Kayu teras nangka (Artocarpus heterophyllus Lamk) diketahui memiliki ketahanan terhadap rayap tanah. Penelitian ini bertujuan untuk menentukan kadar zat ekstraktif kayu teras nangka, menguji sifat bioaktivitas ekstrak kayu teras nangka terhadap rayap tanah dan menganalisis senyawa kimia ekstrak yang memiliki sifat bioaktivitas anti rayap tertinggi. Ekstrak kayu teras nangka larut aseton selanjutnya dilakukan fraksinasi bertingkat secara berturut-turut dengan pelarut n-heksan, etil eter dan etil asetat. Setiap fraksi dibuat konsentrasi 2, 4, 6, 8 dan 10% untuk pengujian rayap tanah dan identifikasi fraksi teraktif dengan GC-MS. Hasil penelitian menunjukan bahwa kadar zat ekstraktif kayu teras nangka larut aseton diperoleh sebesar 8.29%. Fraksi n-heksan memiliki aktivitas anti rayap tertinggi berdasarkan persentase mortalitas dan kehilangan berat. Berdasarkan analisis GC-MS pada fraksi n-heksan terdapat lima senyawa dominan yaitu 1,2–Benzenedicarboxylic acid, bis (2-ethylhexyl) ester (CAS), (23S)-ethylcholest-5-en-3. Beta.–ol 24.XI, Stearic acid, n-undecane dan n-dodecane.

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
