Judul: Diagnosa Spesies dan Penanggulangan Babesiosis pada Sapi
Abstrak: Babesiosis adalah penyakit menular yang khas pada sapi yang disebabkan oleh protozoa parasitik perusak sel darah merah yang termasuk dalam genus Babesia. Penyebab babesiosis pada sapi adalah Babesia bigemina, B. bovis, B. major dan g, divergens. Jenis babesia yang lain yang juga menyerang sapi adalah EJ. argentina dan B. berbera tetapi Nahoney (1977) menganggap bahwa kedua jenis babesia tersebut adalah sinonim daripada -B. bovis. Serangan daripada parasit babesia tersebut biasanya menyebabkan kerusakan eritrosit yang hebat sehingga hewan menderita anemia yang bisa berakibat kematian hewan bila tidak segera mendapat pengobatan.

Judul: Babesiosis pada kambing dan domba
Abstrak: Babesiosis adalah penyakit hewan menular yang tidak ditularkan secara kontak yang dapat bersifat akut atau kronis (menahun) dan disebabkan oleh parasit protozoa yang menyerang dan merusak sel darah merah yang termasuk dalam genus Babesia. Penyebab babesiosis pada kambing dan domba adalah Babesia motasi, Babesia ovis, Babesia foliata dan Babesia taylori. Tetapi Richardson dan Kendall (1957, dalam Le vine, 1961) menganggap bahwa B. foliata adalah sinonim dari B. ovis. Serangan parasit Babesia tersebut biasanya menyebabkan kerusakan eritrosit yang hebat sehingga hewan menderita anemia yang dapat mengakibatkan kematian hewan bila tidak segera mendapat pengobatan. Dalam mendiagnosa penyakit ini sebaiknya dilakukan sedini mungkin dengan cara mengetahui sejarah, gejala klinik dan dengan memeriksa infestasi caplak serta melakukan preparat ulas darah. Berdasarkan pengetahuan tentang morfologi dari masing-masing jenis Babesia pada kambing dan domba, dapatlah ditentukan diagnosa jenis (spesies)nya. Pemeriksaan secara serologis dapat dilakukan untuk lebih meyakinkan diagnosa. Selain dengan cara pengobatan pada hewan-hewan sakit penanggulangan babesiosis dapat pula dilakukan dengan cara memberikan preimunisasi pada hewan-hewan yang peka terhadap babesiosis serta mengadakan pemberantasan jenis caplak yang bertindak sebagai vektor dari parasit ini.' Mengkarantinakan hewan-hewan yang akan dimasukkan ke In donesia dapat pula dilakukan dalam penolakan dan pence gahan penyakit ini.

Judul: Algorithm construction of HLI hash function
Abstrak: Cryptography is a study of mathematical techniques related to aspects of information security regarding on confidentiality, data integrity, entity authentication, and data origin authentication. Data integrity is a service, which is associated with the conversion of data carried out by unauthorized parties. To maintain data integrity, one can use hash functions. An hash function is a computationally efficient function to map an arbitrary length bitstring to a fixed length bitstring called as hash value. The use of hash function in maintaining the information integrity and authentication is in digital signatures, virus protection, and software distribution. Illustration of the hash function in the integrity and authentication of information that is emailed as follow. The sender sends the information and hash value to the recipient. If the hash value of the information is equal to the hash value that is sent by the sender, then information has not been changed. Otherwise the information has been changed. An hash function has two properties, one way and collision resistance. An hash function is called one way if it is computationally infeasible to find any input such that when given any hash value . Meanwhile an hash function is called collision resistant if it is computationally infeasible to find any two inputs where such that . The purpose of this study is to construct a HLI hash function algorithm, to analyze the speed and security of the hash functions as a results of construction. Furthermore, it is to compare it with SWIFFT. Hash function is constructed based on the result of algebraic operations on modular polynomial ringwith . Modular polynomial ring noted as is a set of all polynomials of degree at most with coefficients in . can be represented as a set of integer vector of modulo in dimension . So, it is simple to implement in a computer. In vector operations, is lattice . Furthermore, alattice that is defined from certain polynomial ring is called ideal lattice. HLI hash function is consists of addition and multiplication algorithm in the ring. Addition algorithm consists of sumation operations of modulo and multiplication consists of multiplication operations of modulo . Generally, algorithm of HLI hash function consists of multiplication operations of modulo and addition operations of modulo . However, if the input is binary number then multiplication algorithm only consists of multiplication operation of modulo , so algorithm of HLI hash function consists of multiplication operations of modulo and addtion operations of modulo . An hash function is secured if it has two properties, i.e., one way and collision resistance. HLI hash function hash is one way, it is following the proof of Micciancio. It is has collision resistant because of polynomial is irreducible over and monic. Moreover, it is proved that for every unit vector , the vector is small vector. If the input of hash function is a binary number then HLI hash function only involves addition operations of modulo . So the time that used almost same with SWIFFT. The excellence of HLI hash function is the key size smaller than SWIFFT. This effect on
