Judul: Effect of Concentration of Medium and Boiling Time in Processing of Attacus atlas Cocoon and The Effects on Filamen Quality.
Abstrak: Attacus atlas was one of wild silkworm species that spreads around Indonesia. In pupa stage, A. atlas formed brown color cocoon that was the last product in silkworm sericulture. Cocoon of A. atlas has different characteristic with cocoon of the domestic silkworm Bombyx mori. It caused cocoon of A. atlas can not be proceed by the boiling process that commonly used in processing cocoon of B. mori. Therefore, special treatment and chemical compound addition are needed to process cocoon of A. atlas. The research aims to find the best chemical compound concentration and optimal boiling time to process cocoon of A. atlas and observe the treatment effect on the quality of filament. The research used two factors such as concentration of NaOH and boiling time. Concentration of NaOH that were used are 0.5 g/l (N1), 1g/l (N2), 2g/l (N3), and 3g/l (N4), while the boiling time that were used are 1 hour (T1) and 2 hours (T2). Based on ANNOVA testing, each treatment produced no significant difference (P>0.05) on the length and weight of filament also the number of filament broken. Meanwhile, based on the mean value of the length and weight of filament, N3T2 treatment showed the highest value than other treatment. The visual observation showed each treatment produced different characteristics of filament. The good quality of filament was produced by N3T1 treatment that was shown by the good color and strength of filament also the ease of cocoon processing.

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.
