Judul: Laboratory Evaluation of The Efficacy of Pine Wood Pellets with 0,25% Hexaflumuron Active Against The Subterranean Termite Coptotermes curvignathus
Abstrak: Umpan rayap berbahan aktif hexaflumuron merupakan teknologi pengumpanan yang ramah lingkungan. Formulasi umpan menggunakan kayu tusam sebagai bahan tambahan. Kandungan resin kayu tusam mengurangi kesukaan rayap terhadap kayu tusam sehingga perlu dikurangi agar tingkat kesukaan rayap meningkat. Penelitian ini bertujuan untuk mengevaluasi efikasi formulasi umpan pelet dari kayu tusam (Pinus merkusii) yang diberi perlakuan pendahuluan presto (0,4 bar, 100 °C) kemudian diberi bahan aktif hexaflumuron 0,25% terhadap rayap Coptotermes curvignathus. Serpihan kayu tusam di presto selama satu, dua, tiga, empat dan lima jam sebagai perlakuan kemudian dihaluskan (40-60 mesh) dan ditambah hexaflumuron (0,25%). Campuran dibentuk pelet lalu diumpankan terhadap rayap tanah C. curvignathus (JIS K 1571:2010). Hasil penelitian menunjukkan bahwa ketermakanan formulasi pelet berbahan aktif hexaflumuron (14,33%) lebih tinggi dibanding kayu tusam solid (6,58%). Formulasi umpan pelet berbahan aktif hexaflumuron 0,25% dengan perlakuan pendahuluan presto mampu mengeliminasi rayap tanah C. curvignathus., Termite bait with active ingredient hexaflumuron is an environmentally friendly baiting. The bait formulation used pine wood as an additive. The resin content in pine wood can reduce termites preference for pine wood so it needs to be reduced so that the level of termites preference can be increased. This study aims to evaluate the efficacy of the bait formulation of pellets from pine wood (Pinus merkusii) which was pretreated with presto (0,4 bar, 100 °C) with 0,25% active ingredient hexaflumuron against termites Coptotermes curvignathus. The treated chips then made into sawdust (40-60 mesh) and added with hexaflumuron (0,25%) and formed into pellets then fed to the subterranean termites C. curvignathus (JIS K 1571:2010). The results showed that palatability of formulation pellet bait with active hexaflumuron (14.33%) was higher than solid pine wood (6,58%). The formulation of pellet bait with 0,25% active hexaflumuron with presto pre-treatment was able to eliminate the subterranean termite C. curvignathus.

Judul: Pengujian Laboratoris Efikasi Hexaflumuron 0.5% terhadap Rayap Tanah Coptotermes curvignathus Holmgren (Isoptera: Rhinotermitidae)
Abstrak: Subterranean termite Coptotermes curvignathus Holmgren (Isoptera: Rhinotermitidae) is the most important buildings destructing insects in Indonesia. Up to now, soil treatment and wood preservation are the most popular termite control techniques in urban areas. However, applications of both techniques could causing environmental pollution. Meanwhile termite baiting is known as more environmentally friendly termite control technique. One of the active ingredient used in the baiting system is hexaflumuron. A laboratory study was conducted to determine the efficacy of two formulations of hexaflumuron 0.5 % i.e blocks formulation and pellet formulation, against subterranean termite C. curvignathus based on PSIH-IPB-1998 standard methods. The results showed that both formulations of hexaflumuron 0.5 % is effective to eliminate the C. curvignathus. However, palatability of pellet formulation (49.43 %) is much higher than palatability of blocks formulation (8.52 %)

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
