Judul: Perancangan dan Analisis Protokol Keamanan Data Pada Sistem Ujian Online
Abstrak: Examination is an evaluation step of learning process, aimed at measuring level of success of the process. Conventional examination system with paper media is effective and efficient with few test participants, centralized location and flexible time. However, it is not effective with a large number of participants, scattered locations, and simultaneous time, like the National Final Examination (Ujian Akhir Nasional – UAN) and Public University Entrance National Selection (Seleksi Nasional Masuk Perguruan Tinggi Negeri – SNMPTN). Therefore, a reliable, fast and accurate examination system, utilizing Internet is required. The alternative method is an online examination system using computer and internet connection. The system requires availability of clear and accurate data which can only be accessed by authorized person. The common technique to secure data within internet media is cryptography. It is used to keep the information security of the data, so that unauthorized person cannot access it. The research is conducted to produce a protocol design that can be used to secure data relevant to the online examination system. The research method used security basic need analysis and Security Life Cycle (Bishop 2003). The data security protocol design is implemented by Power Builder 10.0 Build 4500 programming language and library java of Java Cryptographic Extension (Weiss 2003). The result is data security protocol framework that conform to the security requirement of the online examination system.

Judul: The Analysis and Development of IPB Online Voting Centre Based on Two Central Facilities Protocol.
Abstrak: The election can be developed as an alternative to a conventional election that has many shortages, especially in security issues. Security of the virtual election can be assured if the election apply the most appropriate cryptographic protocol. This research carried out by four students, has developed virtual election based on two central facilities protocol. The difference with other protocol is that the new system implementing two institutions into two different servers. These institutions are Central Legitimization Agency (CLA) and Central Tabulating Facility (CTF). This system is also equipped with a secure sites since the central information take place during the election and registration facilities that make the voters registration process easily. This site is run safely through the secure socket layer to encrypt each data sent so the process of transferring file avoid from falsification of data. Keyword: cryptographic protocol, two central facilities, Central Legitimization Agency, Central Tabulating Facility, secure socket layer, encrypt.

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
