Judul: Effect of Lighting and Feed to the Growth of the Yellow Mealworm Tenebrio molitor L. (Coleoptera: Tenebrionidae)
Abstrak: Ulat hongkong merupakan sebutan (nama umum) untuk fase larva dari kumbang Tenebrio molitor. Serangga Tenebrio molitor sering menjadi hama karena dapat menyerang produk makanan di gudang penyimpanan yang dapat menyebabkan tingkat kerugian yang tinggi. Pada fase larva, ulat hongkong memiliki banyak manfaat karena memiliki nilai protein yang tinggi sehingga sering digunakan untuk pakan ternak sehingga banyak dikembangbiakkan. Keberhasilan pembiakan ulat hongkong ditentukan oleh banyak faktor, antara lain pakan dan lingkungan pemeliharaan yang dapat memengaruhi perkembangan ulat hongkong dari mulai fase telur sampai imago. Penelitian ini dirancang untuk mengetahui pengaruh pencahayaan dan pakan terhadap perkembangan ulat hongkong. Ulat hongkong dipelihara dan diletakkan di dalam wadah, lalu diberikan dua macam makanan yang berbeda yaitu pakan pur ayam dan pollard. Selanjutnya pada setiap perlakuan makanan diberikan perlakuan cahaya terang, gelap, dan kontrol (gelap dan terang). Adapun faktor yang diamati yaitu, suhu dan kelembapan ruangan, panjang tubuh serangga, lama periode tiap fase serangga, dan mortalitas serangga. Hasil pengamatan menunjukkan bahwa faktor pakan dan cahaya berpengaruh terhadap perkembangan ulat hongkong. Larva dengan pakan pur ayam memiliki tubuh yang lebih panjang (2,54 cm) dibandingkan dengan yang diberi makanan pollard (1,76 cm). Lama perkembangan larva dengan pakan pur ayam lebih singkat dibanding dengan pakan pollard. Pada perlakuan pencahayaan, cahaya terang menyebabkan mortalitas larva yang lebih tinggi, yakni 30,5% pada pakan pur ayam dan 49% pada pakan pollard dibandingkan dengan perlakuan gelap (2% dan 5,5%), maupun pada kontrol (2,5% dan 4%).

Judul: Performa ulat tepung (Tenebrio molitor L.) pada suhu dan kelembaban yang berbeda
Abstrak: Yellow mealworm is the larval stage of Tenebrio molitor L. beetle. Nowadays, yellow mealworms are reared because of its economic value. Yellow mealworm can be used for feed and food. The growth of yellow mealworms is influenced by temperature and humidity, so a suitable combination of temperature and humidity is necessary for yellow mealworm optimal production.The research was done from July 1 5u~p t o Oktober lo* 2005 at Non Ruminants and Prospective Animals Division, Departement of Animal Production and Technology, Faculty of Animal Science, Bogor Agricultural University. The purpose of this research was to compare the yellow mealworms (Tenebrio molitor L.) growth performances at different temperature and humidity. This research used 1500 yellow mealworms aged 35 days old. The experiment used Completely Randomized Design in 2x2 factorial experiment. The first factor was temperature (29 and 31 OC) and the second factor was humidity (69% and 71%). Each treatment combination had five replicates which consisted 75 yellow mealworms. The observed variables were feed consumption, body lenght and weight gain, feed conversion based on body lenght and weight gain, and mortality. Data were analyzed by using ANOVA and tested with Least Significant Difference Test (SAS 6.12) to know the difference among the treatments. The result showed that the lower temperature (29 OC) with higher humidity (71%) gave the best growth performances for 35-65 days old yellow mealworms. Otherwise, the best growth performances for 65-75 days old yellow mealworms were at higher temperature (3 1 OC) with lower humidity (69%).

Judul: Simulasi Protokol Autentikasi Pelanggan pada Voice Privacy
Abstrak: Existing design of the telephone public network is susceptible to eavesdropping on its voice stream. Consequently, any wire taper can listen to supposedly private conversation. In order to prevent such eavesdropping, we propose a protocols and its implementation for end-to-end voice privacy authenticate as a service available for interested subscribers. Our protocols consist of customer enrollment system, customer authentication system and simulation voice privacy. Protocols that we made are adaptation from Sharif and Wijekesera journal with the title Providing Voice Privacy as a Service over the Public Telephone Network. The result of the process shows how the customer enrolls and how the system process the password, how the system authenticate customer simulate voice privacy.
