Judul: Subterranean Termite Attack on Tree Stands in Bogor Botanical Garden
Abstrak: Pelestarian dan perlindungan terhadap pohon-pohon yang tersimpan di Kebun Raya Bogor (KRB) perlu dilakukan untuk menghindari kerusakan oleh berbagai macam penyakit maupun serangga perusak termasuk rayap. Penelitian bertujuan menganalisis frekuensi serangan rayap dan mengidentifikasi jenis rayapnya, menganalisis preferensi rayap terhadap jenis pohon, serta tingkat kerusakan pohon akibat serangan rayap di KRB. Penelitian dilakukan dengan menggunakan metode jalur sampling. Hasil penelitian menunjukkan bahwa sebanyak 213 (100%) pohon contoh di KRB terserang rayap. Spesies rayap tanah yang ditemukan sekurang-kurangnya terdapat empat spesies yaitu Coptotermes curvignathus Holmgren, Macrotermes gilvus Hagen, Odontotermes javanicus Holmgren dan Nasutitermes matangensis Haviland. Rayap M. gilvus banyak ditemukan pada pohon Pterocarpus indicus, Dysoxilum spp., Shorea spp., dan Dimocarpus spp.. Rayap O. javanicus banyak ditemukan pada pohon Vitex cofassus, Dehaasia incrassata, Heriteria spp., dan Cordia spp.. Rayap N. matangensis banyak ditemukan pada pohon Philodendrom spp., Dysoxilum spp., dan Sindora spp.. Rayap C. curvignathus banyak ditemukan pada pohon Araucaria columnaris, Agathis sp., dan Pinus spp. Tingkat kerusakan pohon contoh akibat serangan rayap sebesar 10-90%., Preservation and protection of trees stored in the Bogor Botanical Gardens (KRB) need to be done to prevent damage by various kinds of diseases and destructive insects including termites. This study aimed to analyze the frequency of termite attacks and to identify the type of termites, to analyze termite preferences for tree species, as well as the degree of tree damage due to termite attacks in KRB. The research was conducted using the path sampling method. The results showed that as many as 213 (100%) sample trees in KRB were attacked by termites. There are at least four subterranean termite species found, namely Coptotermes curvignathus Holmgren, Macrotermes gilvus Hagen, Odontotermes javanicus Holmgren, and Nasutitermes matangensis Haviland. Termites M. gilvus are found in Pterocarpus indicus, Dysoxilum spp., Shorea spp., and Dimocarpus spp. Termites O. javanicus are found in Vitex colossus, Dehaasia incrassate, Heriteria spp., and Cordia spp. Termites N. matangensis is found in Philodendrom spp., Dysoxilum spp., and Sindora spp. Termites C. curvignathus can be found in Araucaria columnaris, Agathis sp., and Pinus spp. The level of damage to sample trees due to termite attacks is 10-90%.

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
