Judul: Pengembangan sistem keamanan transaksi peta digital menggunakan teknik kriptografi
Abstrak: Peta digital (shapefile) pada bidang tertentu memerlukan biaya yang besar dalam proses pembuatannya, sehingga memerlukan layanan keamanan berupa perlindungan dari pengaksesan serta penggandaan secara ilegal. Salah satu cara untuk memberikan layanan keamanan tersebut yaitu dengan mengimplementasikan teknik kriptografi pada proses transaksi shapefile. Penelitian ini mengembangkan suatu sistem keamanan transaksi untuk shapefile dengan mengkombinasikan algoritma advanced encryption standard (aes), algoritma rivest shamir adleman (rsa), dan teknik steganografi citra least significant bit (lsb) yang dapat memberikan layanan kerahasiaan dan autentikasi. Sistem dikembangkan menggunakan metode pengembangan security life cycle yang dimodifikasi. Penelitian ini menghasilkan sistem transaksi shapefile berbasis web yang dilengkapi dengan layanan keamanan berupa kombinasi ketiga algoritma yang telah disebutkan di atas. Hasil pengujian menunjukkan bahwa sistem telah memenuhi layanan keamanan kerahasiaan dan autentikasi.

Judul: Pengembangan Bagian Offline pada Shapefile Encryption System (SES)
Abstrak: Geographical Information System (GIS) data are classified as expensive and sensitive data. The biggest threat to be dealed by GIS data at the moment is the spread of illegally accessed and distributed by unauthorized party. Currently, most of protection methods that are applied on GIS data focused on the use of digital watermarking. But, this method does not restrict GIS data from being accessed and distributed illegally. This research intends to develop a protection system for GIS data in shapefile form by combining Advanced Encryption Standard (AES) algorithm, Rivest Shamir Adleman (RSA) algorithm, and image steganography technique Least Significant Bit (LSB) which can provide confidentiality and authentication service. As a result, a standalone application is built using the security life cycle development method. The application is being tested on five different shapefile data to measure the effect from four different RSA key lengths towards the execution times needed to perform encryption and decryption process.

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
