Judul: Embryonic Development of Attacus atlas L. (Lepidoptera: Saturniidae)
Abstrak: Attacus atlas was one of wild silkworm species that has been developed in Indonesia as an alternative silk source to domestic silkworm Bombyx mori. A. atlas was spread in tropical and subtropical rain forest and can be found almost in entire Indonesian islands. It has complete metamorphosis stage, including egg (embryo), larvae, pupa, and imago (adult). Embryogenesis was an important stage to know the physiology characteristic of insect such as diapauses. The research aimed to know the embryogenesis of A. atlas. The observation of embryonic development was done in two ways, observation within the eggshell and without the eggshell. The embryogenesis in A. atlas was done in seven days. Morphological observation on A. atlas embryo can be divided as pre-organogenesis and organogenesis stage. Pre-organogenesis stage occurred in first to fourth day after oviposition. Organogenesis stage can be observed in fifth to seventh day after oviposition. In the fifth day, body segmentation was completed. In the sixth day, cephal section and patterning of appendages was completed. Besides, the pigmentation of cephal also occurred in sixth day. In the seventh day, the pigmentation of entire body was completed and embryo was ready to hatch. In the eight day after oviposition embryo was hatching by cracking the eggshell.

Judul: Biologi Attacus atlas L. (Lepidoptera: Saturniidae) dengan pakan daun kaliki (Ricinus communis L.) dan jarak pagar (Jatropha curcas L.) di laboratorium.
Abstrak: The wild silk moth A. atlas L. is being tried for sericulture in Indonesia. The objectives of this research to find out the feeding consumption, the larvae growth, life-cycle, cocoon and filament quality in A. atlas which is raised inside a room. This research was conducted from March 2007 to May 2008. The research comprises two steps: First, analytical proximate castor (R. communis L.) and purging nut (J. curcas L.) leaves; second, silk moth treatment which is done in the laboratory of Molecular Biology PPSHB IPB. The elements used in this research were: cocoon A. atlas and three types of leaves, which are, sirsak (A. muricata L.), castor and purging nut. The research uses Completely Randomize Design. The data resulted is analyzed by Analyze of Variance proceeded by Duncan Tes. The analyzed parameter is feeding consumption, life-cycle, larvae growth, cocoon and filament quality. The total largest food consumption on the larvae feeding on purging nut leaves is 155.09±0.68 g. The increase of larvae’s length and weight is not really present. The shortest life-cycle happen in larvae feeding on castor (60.80±8.37 days). The highest floss and weight decreasing along the cocoon process happens on larvae feeding on castor (66.22±5.85 %) and purging nut (64.53±4.18 %) leaves. The highest cocoon (9.46±1.70 g) and cocoon skin (1.74±0.79 g) weight are on larvae feeding on sirsak leaves. The percentage of cocoon silk does not differ much. The highest cocoon filament length is on the larvae feeding on sirsak leaves (146.84±138.83 m). The cocoon filament weight does not significantly different much. The lowest cocoon distangling capacity is on larvae feeding on castor leaves (12.20±6.65 %). Sirsak leaves feeding on the larvae is superior in filament and cocoon quality, castor leaves feeding on larvae is superior in the fastest life-cycle, and purging nut feeding on the larvae is superior in the largest feeding consumption.

Judul: Sistem Keamanan Parkir Berbasis RFID dan Standar Nirkabel IEEE 802.11b/g Menggunakan Raspberry Pi
Abstrak: Jumlah kendaraan bermotor meningkat setiap tahunnya dan juga tempat parkir. Area parkir dan pengelolaan yang tidak tepat dapat menyebabkan pencurian kendaraan bermotor. Penelitian ini mengusulkan suatu sistem manajemen keamanan parkir yang dapat membantu untuk mengurangi pencurian kendaraan bermotor. Sistem ini terdiri atas sebuah gerbang yang dikendalikan oleh komputer, radio frequency identification (RFID), dan aplikasi berbasis web yang terhubung ke tempat parkir melalui standar nirkabel IEEE 802.11b/g. Setiap pengendara harus memiliki kartu RFID untuk memasuki tempat parkir. Pengendara akan mendekatkan kartu pada RFID card reader dan sistem akan mencatat semua kegiatan. Sistem ini menggunakan Raspberry Pi Model B sebagai pengganti desktop komputer untuk mencatat dan memantau kegiatan pengendara. Hasil pengujian menunjukkan bahwa sistem dapat diandalkan dengan akurasi 100% dan waktu proses rata-rata 6.12 detik. Seluruh sistem dapat bekerja dengan baik dalam kondisi yang mungkin terjadi pada empat skenario pengujian, yaitu: pengujian pembacaan kartu RFID, pegujian posisi kartu RFID, pegujian waktu respon, dan pengujian akurasi/kehandalan.
