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: Perubahan Profil Eritrosit Sapi Perah Akibat Infeksi Babesia Sp. di Lembang, Bandung.
Abstrak: Babesiosis adalah penyakit yang disebabkan oleh Babesia sp. yang penyebarannya meluas di dunia. Babesia sp. diklasifikasikan sebagai parasit intraeritrosit sehingga menyebabkan kerusakan pada eritrosit. Penelitian ini bertujuan untuk melihat Perubahan Profil Eritrosit Sapi Perah Akibat Infeksi Babesia Sp. di Lembang, Bandung. Pengambilan sampel darah dilakukan melalui vena coccygea pada pangkal ekor sapi. Penelitian ini menggunakan 12 ekor sapi perah yang dibagi menjadi dua kelompok: 6 ekor sapi sebagai kontrol negatif dan 6 lainnya sebagai sampel positif dengan Babesiosis. Hasil dari kontrol positif menunjukkan persentase rata-rata parasitemia adalah 0.37%, jumlah rata-rata total nilai eritrosit (positif 6.12 ± 0.54 x 106/μl sedangkan negatif 6.83 ± 0.24 x 106/μl), konsentrasi hemoglobin (positif 9.30 ± 0.49 g/dl sedangkan negatif 10.75 ± 0.33 g/dl) dan hematokrit (positif 28.67 ± 1.75% sedangkan negatif 33.33 ± 1.37%). Adapun nilai indeks adalah MCV eritrosit (positif 46.0 ± 3.6 fl sedangkan negatif 48.83 ± 2.64 fl), MCH (positif 14.50 ± 1.52 pg sedangkan negatif 15.83 ± 0.41 pg), dan MCHC (positif 32.5 ± 0.55 gr/dl sedangkan negatif 32.33 ± 0.55 gr/dl). berdasarkan persentase parasitemia menunjukkann bahwa parasitemia pada sapi perah berada di dalam kategori ringan, jenis anemia dalam penelitian ini berdasarkan pada nilai MCV dan MCHC pada sapi perah yang terinfeksi Babesia sp. menunjukkan anemia normositik hipokromik.

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
