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.

Abstrak: Attacus atlas L. (Lepidoptera: Saturniidae) is one of Indonesian native insect that has a great potential economy. Fulfillment the demand of material for silk thread still rely that exist in nature, therefore, needs to be done with the use of intensive breeding male imago as effective as possible in mating. The aim of this research was to study the reproduction performance of male imagoes of wild silkworm A. atlas. This research was conducted by allow a male imago mate with three different females. The time of each mating was 6 hours. The parameters observed were the first, second and third ejaculate volume, the number of eggs per imago, egg hatching time and hatchability of eggs. The results showed that the frequency of mating significantly affect the percentage of egg hatchability. The optimum value was achieved at first mating was 53.58 ± 18.26%. The percentage of egg hatchability declined with increasing frequency of mating. The number of eggs per imago and egg hatching time was not influenced by the frequency of mating with the average number of eggs per imago 225.86 ± 34.23 eggs and the average time of hatching eggs was 11.20 ± 3.23 days

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.
