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: Aplikasi Keamanan Data Shapefile Menggunakan Algoritme Kriptografi AES
Abstrak: Geographic Information System (GIS) is an important part of information systems because GIS contains classified spatial data and information in any fields. This research is focused on securing GIS vector data (shapefiles) and also reading the shapefiles. A shapefile combines maps and tables, both have a related information on each other. The usage of Rijndael (AES) cryptography algorithm and Key Derivation Function (KDF) would assist in improving the security of shapefiles. However, besides cryptography algorithm, authentication service is also implemented to improve the security mechanism in order to prevent unauthorized users gain full access to the application which provides the shapefile security. The application was executed using fifteen shapefiles and analyzed in terms of loading time, size, and iteration count between the encrypted and non-encrypted shapefiles. The biggest shapefile (33.79 MB) could be decrypted and displayed in two seconds with 10000 iterations (ten times in complexity from the standard iteration, which is 1000) and fifteen characters of salt. By using this application, authorized users could read their shapefiles with common functions (zoom, extent, pan, etc) and protect the classified one with no penalty in overall performance.

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
