Judul: Implementasi Public Key Infrastructure untuk Keamanan Sistem Pengiriman Data Pilkada Via Mobile
Abstrak: Cryptography is a process of encrypting data into a form that can be read only by a system. The system has a key to read the encripted data. Based on the method, cryptographic algorithms can be divided into asymmetric key cryptography, symmetric key criptography, and public key cryptography. This research attemps to develop Public Key Infrastructure (PKI) with integrity service, which is implemented in the transmission of voting results in mobile election process. The benefits of this research is to simplify and improve the efficiency of the counting process and improving the security of the data transmission using mobile communication. The method employed is the Life Cycle Security System in which a sequence of steps following the life cycle of security system by eliminating the operational and maintenance step. The algorithm used in this research are RSA and MD5 Hash Function. RSA Algorithm is used to facilitate the distribution of keys that was used in the message encryption, and MD5 hash functions as an authentication function. The result of this research is the security system of the transmission of local elections vote via mobile which overcome the threat of sniffing or snooping, camouflage, and alteration with provides security services of authentication, integrity, and availability.

Judul: Pengembangan Sistem Pengiriman Hasil Suara pada E-Voting Two Central Facilities yang Dimodifikasi
Abstrak: Election system in Indonesia still uses conventional method that has many disadvantages such as: slow voting result's calculation, slow voting result's transmission to the central committee, and large amount of human resources. E-voting is expected to solve the problems and the most secure election protocol that meets the standards of secure voting requirements according to Schneier (1996) is Two Central Facilities Protocol. The goal of this research is developing voting result transmission system based on modified Two Central Facilities Protocol designed by Kusumah (2012), analyzing the developed transmission system's running time, and determining the influence of cryptographic algorithm usage on developed transmission system's running time. Through this research, we developed a voting result transmission system and found that cryptographic algorithm usage on this system contributes 22.58% of the total system running time which is relatively low. We recommend further research regarding analyzing other factors beside cryptographic algorithm usage and database security implementation on voting result transmisson system.

Judul: Karakteristik Anatomi Skelet Kepala Buaya senyulong (Tomistoma schlegelii).
Abstrak: Buaya sepit atau senyulong (Tomistoma schlegelii) merupakan jenis buaya asli Indonesia yang berhabitat di sungai-sungai Sumatera, Kalimantan, dan juga pedalaman Sulawesi. Salah satu ciri khas buaya senyulong adalah bentuk moncong yang runcing dan sempit, namun hingga saat ini informasi mengenai struktur skelet kepala buaya senyulong sangat terbatas. Penelitian ini bertujuan untuk mempelajari karakteristik anatomi skelet kepala buaya senyulong yang dikatikan dengan fungsi dan perilakunya. Penelitian dilakukan secara eksploratif dengan melakukan pengamatan, pencatatan, dan pengambilan gambar dari skelet kepala buaya senyulong. Skelet kepala berukuran panjang 70 cm, lebar 29 cm, dan tingggi 17 cm dengan permukaan kasar pada os nasale, os frontale, os maxilla, os mandibula, os lacrimale, os jugale. Jumlah gigi pada buaya ini sebanyak 78 buah, terdiri dari 4 buah gigi premaxila, 16 buah gigi maxila, dan 19 buah gigi mandibula. Pada regio orbitalis ditemukan dua pasang fenestrae temporales yang berkembang baik. Fenestra supratemporale merupakan lubang oval yang membentang di sepanjang os parietale. Fenestra infratemporale berbentuk segitiga dan dibatasi oleh os squamosum, os postorbitale, os jugulare, dan os quadratum. Os mandibula hewan ini mempunyai symphysis mandibularis yang panjang yaitu garis yang melintang di corpus mandibulae. Secara fungsional ukuran symphysis mandibularis berkaitan dengan adaptasi hewan terhadap diet makan.
