Judul: Biology and Symptoms of Pest Ephestia cautella Walker (Lepidoptera: Pyralidae) on Peanut Seed
Abstrak: Kacang Tanah (Arachis hypogaea L.) merupakan tanaman pangan yang termasuk ke dalam famili Fabaceae. Biji kacang tanah memiliki kandungan protein yang tinggi sehingga banyak diminati. Namun, beberapa tahun terakhir terjadi penurunan kualitas pada biji kacang tanah selama masa penyimpanan yang disebabkan adanya serangan hama gudang. Ephestia cautella merupakan hama gudang dari famili Pyralidae yang menyebabkan kerugian pada produk pascapanen salah satunya pada gudang penyimpanan biji kacang tanah. Penelitian ini bertujuan mempelajari biologi dan gejala serangan E. cautella pada biji kacang tanah. Pengamatan dilakukan dengan menggunakan 100 individu serangga, terdapat 10 ulangan dan pada setiap ulangan berisi 10 individu. Pengamatan dilakukan untuk melihat morfologi, siklus hidup, dan gejala serangan pada biji kacang tanah. Siklus hidup E. cautella terdiri dari empat fase yaitu telur, larva, pupa, dan imago. Siklus hidup E. cautella berlangsung selama 49 hari, dengan stadium telur berlangsung selama 4 hari, stadium larva selama 25 hari, stadium pupa selama 13 hari, lama hidup imago jantan selama 15 hari, dan lama hidup imago betina selama 17 hari. Serangga jantan dan betina dapat dibedakan pada bagian abdomen. Gejala serangan dari larva E. cautella mengakibatkan biji kacang tanah berlubang dan saling menempel akibat benang-benang halus yang dibuat larva instar akhir., Peanuts (Arachis hypogaea L.) belongs to the Fabaceae family and is a food crop. Peanuts seeds have a high protein content and are therefore in high demand. However, in recent years there has been a decline in producers in storage warehouses due to warehouse pest attacks. Ephestia cautella is a warehouse pest from the Pyralidae family that causes losses in postharvest products, one of which is in peanut seed storage warehouses. This research aims to study the biology and symptoms of E. cautella attack on peanut seeds. Observations were made using 100 individual insects, there were 10 replicates and each replicate contained 10 individuals. Observations were made to see the morphology, life cycle, and symptoms of attack on peanut seeds. The life cycle of E. cautella consists of four phases: egg, larvae, pupa, and adult. The life cycle of E. cautella lasts for 49 days, with the egg stage lasting for 4 days, the larval stage for 25 days, the pupa stage for 13 days, the life span of male imago for 15 days, and the life span of female imago for 17 days. Male and female insects can be distinguished on the abdomen. Symptoms of E. cautella larvae infestation result in hollow peanut seeds and sticking together due to the fine threads made by the late instar larvae

Judul: Soybean canopy dwelling predatory arthropods with the emphasis on Paederus fuscipes (Curt.) (Coleoptera: Staphylinidae)
Abstrak: Penelitian dilaksanakan pada lahan kedelai di Kecamatan Ciranjang, Kabupaten Cianjur, Jawa Barat pada musim kemarau 1997 dan 1998, dan bertujuan untuk menganalisis kompleks predator penghuni tajuk serta peranannya di pertanaman kedelai, memahami perkembangan populasi dan tingkat pemangsaan kumbang Paederus fuscipes (Curt.) (Col.: Staphylinidae), mengkaji pengaruh pemberian mulsa jerami terhadap kelimpahan populasi P. fuscipes, serta mengukur preferensi dan tanggap fungsional P. fuscipes. Hasil penelitian menunjukkan bahwa tajuk kedelai dihuni oleh lebih dari 25 spesies artropoda predator. Predator yang paling dominan adalah kumbang P. fuscipes (Curt.), cengkerik Anaxipha longipennis (Serville) dan laba-laba Pardosa pseudoannulata (Boes. & Str.) dan Atypena adelinae (Barr. & Lit.). Besarnya tekanan pemangsaan oleh predator penghuni tajuk dipengaruhi oleh kelimpahan predator dan fase pertumbuhan tanaman Tekanan pemangsaan terhadap telur mencapai 50% dari total 60 telur, dan terhadap larva mencapai 58% dari total 60 ekor larva yang diumpankan. Fase perkembangan tanaman dan kelimpahan predator mempengaruhi besarnya tekanan pemangsaan. Dengan kerapatan predator 1,47 ekor per rumpun, tekanan pemangsaan terhadap telur pada fase V4 mencapai 48% dari total 60 telur, sedangkan terhadap larva mencapai 67% dari total 60 ekor larva yang diumpankan. Tekanan pemangsaan lebih tinggi pada fase ~ (60% untuk telur, dan 68% untuk larva) yang disebabkan oleh meningkatnya kerapatan predator yang mencapai sekitar 3 ekor per rumpun., Studies were conducted on soybean fields in the sub district of Ciranjang, Cianjur, West Java during the two growing soybean seasons of 1997 and 1998, with the objectives: to analyze the soybean canopy dwelling predatory arthropods and its roles, to analyze the population development and predation rate of Paederus fuscipes (Curt.) (Col.: Staphylinidae), to assess the effect of mulching of paddy straw on population abundance of P. fuscipes, and to determine the prey preference and functional response of P. fuscipes. Results of the studies showed that soybean canopy was inhabited by more than 25 species of predatory arthropods. The most abundant predators were P. fuscipes beetles, cricket Anaxipha longipennis (Serville) and spiders Pardosa pseudoannulata (Boes. Str. )and Atypena adelinae (Barr. & Lit.). The predation pressure varied with predator abundance and soybean growth stage. The predation pressure on eggs was 50% and on larvae 58%. During the growth stage V4, with a predator density of 1,47/hill, the predation pressure was 48% on eggs and 67% on larvae. During growth stage RJ, with a predator density of 3,39/hill, the predation pressure on eggs was 60% and on larvae 68%. P. fuscipes was present throughout the soybean growing stage, with the peak of population (1,5-2 predator/hill) occurred on 6-7 weeks after planting. Each individual beetle consumed 12-14 eggs or 12 instar-1 larvae of Helicoverpa armigera Hbn. (Lep.: Noctuidae) per day. P. fuscipes showed an adaptive searching behavior for the prey. About 32% of H. armigera eggs placed on the upper surface of the leaves were consumed, compared to 19% on the lower surface. Similarly, 53% and 41% of Etiella zinckenella Tr. (Lep. Pyralidae) eggs placed respectively on shoots and pods were consumed, whereas only 6% on eggs placed on leaves.

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
