Judul: Kualitas kokon hibrid ulat sutera (Bombyx mori L.) berdasarkan umur kokon
Abstrak: Cocoon l~arvestt ime significantly influenced the cocoon quality. Cocoon is harvested when the pupa is formed, the body becomes brown and h e skin is hard enough. The aim of this research was to investigate the influence of cocoon age on the cocoon quality and pupae complete fornl from two silkworn1 hybrids i.e. BS 07 and BS 10, and each hybrid differed by sex. The research was done from 1" to March 3oth 2006. The data were collected from three days old up to six days old cocoon and was analyzed using repeated measures of variance and completely randomized design of factorial pattern 2x2 with 5 replications. If the trearment had significantly effect on the variable that measured, it was continued with Least Squares Means Method. The parameters observed in this research were cocoqn we ght, single shell weight, shell ratio 2nd the complete fo~mo f pupae. The result of this research indicated significantly effect (Pi0,Ol) on cocoon weight, single shell weight and shell ratio and there was interaction among silkworm strain, scx and cocoon age. Cocoon weight, single shell weight and shell ratio were decline from three days old to four days old cocoon. Cocoon weight was decrease at four days old to six days old cocoon, but single shell weight and shell ratio were constant. Mortality between 5 to 10% from thee d;ys old up to six days old cocoon.

Judul: The Growth of Silkworm ( Bombyx mori L. ) New Hybrid and Commersial's Type
Abstrak: Silkworm larvae has a silk gland that produces silk threads. Silk thread quality is obtained from a qualified cocoon. Clean cocoons with no stains and have a strong fiber will havea high value. To attain qualified cocoons then the larvae feed consumption must be taken into account. The feed consumed will affect the growth performances such as body weight and body weight gain which are the most decisive indicator of the quality of cocoon. This study aimed to evaluate the growth of new hybridobtained from reciprocal cross breeding system and commercial type. The Completely Randomized Design was used as the experimental design with six hybrids as the treatment, i.e. H1 (Mainland China rase 808♂ X Japan race 108 ♀), H2 (Mainland China race 903 ♂ X Japan race 806 ♀), H3(Japan race 903 ♀ X Mainland China race 806 ♂), H4 (Mainland China race 808 ♀ X Japan race 108 ♂), H5 (commercial silkworm C301), and H6 (commercial silkworm BS09). The data taken from 30 larvae hybrid each were analyzed by ANOVA (95%) and then by Tukey test. The results showed that H2 (Mainland China race 903 ♂ X Japan race 806 ♀) was superior hybrid than any hybrid based on the variables of feed consumption, body weight gain, feed conversion, and mortality.

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.
