Judul: Ciri morfologi dan siklus hidup parasitoid acerophagus papayae noyes  schauff (Hymenoptera: granara de Willink (Hemiptera: Pseudococcidae) Encyrtidae) pada paracoccus marginatus williams
Abstrak: Penelitian ini bertujuan untuk mengetahui ciri morfologi dan siklus hidup parasitoid A. papayae pada P. marginatus. Penelitian dilakukan di laboratorium dengan mengambil P. marginatus yang terparasit dari lapangan kemudian dimasukkan ke dalam tabung reaksi. Imago parasitoid A. papayae betina yang muncul dimasukkan ke dalam kurungan plastik yang di dalamnya terdapat nimfa instar kedua P. marginatus. Untuk mengamati ciri morfologi dan siklus hidup parasitoid, nimfa P. marginatus yang terparasit dipelihara pada daun pepaya yang ada pada tanaman kemudian, dilakukan pembedahan setiap hari. Untuk mengamati waktu kemunculan imago parasitoid, nimfa P. marginatus yang terparasit dipelihara dalam tabung reaksi. Imago parasitoid A. papayae (betina dan jantan) secara umum berwarna oranye kekuningan dengan sayap yang transparan. Imago parasitoid A. papayae betina dan jantan dapat dibedakan dengan mengamati bentuk antena, warna abdomen dan alat kelaminnya. Parasitoid A. papayae memiliki tipe telur encyrtiform, tipe larva hymenopteriform dan tipe pupa exarate. Siklus hidup parasitoid A. papayae umumnya berkisar 13-15 hari. Waktu kemunculan tertinggi imago parasitoid A. papayae, baik betina maupun jantan, adalah pada kisaran jam 06.00-09.00 WIB dengan nilai persentase lebih dari 85%. Lama hidup imago parasitoid A. papayae betina yang diberi madu rata-rata adalah 7,55 ± 2,54 hari dan lama hidup imago parasitoid A. papayae jantan rata-rata 7,25 ± 3,06 hari. Lama hidup imago parasitoid A. papayae betina dan jantan yang dipelihara tanpa madu berkisar 1-3 hari.

Judul: Quantitative analysis of potency of acerophagus papayae noyes & schauff (Hymenoptera: Encyrtidae), parasitoid of the papaya mealybug
Abstrak: The papaya mealybug, Paracoccus marginatus Williams and Granara de Willink (Hemiptera: Pseudococcidae), was an invasive pest that invaded Indonesia in early 2008 and caused heavy damage on papaya. One of the natural enemies found in Bogor was parasitoid Acerophagus papayae Noyes and Schauff (Hymenoptera:Encyrtidae). The parasitoid was believed to have been fortuitously introduced into Indonesia. Research was conducted to evaluate the potency of A. papayae as biological control agent for the papaya mealybug. Studies included determining various biological parameters such as development time, host preference, functional response, and simulation model of host-parasitoid population dynamics. Parasitoids were obtained from the papaya fields by collecting the mummy of papaya mealybugs and enclosed individually in gelatin capsules. Adult parasitoids emerged were reared on the papaya mealybugs with Jatropha curcas as a host plant. Fitness and preference of the parasitoids were studied using papaya mealybug instar II dan III with a piece of papaya leaf in a test tube (d = 3 cm, h = 15 cm). Functional response of the parasitoids were studied at the host density of 2, 5, 10, 20, 30, 40, and 50 nymphs. Mummies were also collected from the fields, and the data were used to test the sensitivity and validate the model using Stella version 9.02 software. Our study revealed that the parasitoid preferred second-instar over the third-instar nymphs of P. marginatus. Immature developmental time was shorter and survival rate was higher of parasitoids developed on the second-instar nymps. Female parasitoid showed type II functional response with the increasing host density. Our simulation model indicated that the parasitoid had a good searching capacity and was able to regulate papaya mealybug population.

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
