Judul: Gambaran Darah Pada Monyet Ekor Panjang (Macaca fctscicularis) Sebelum dan Sesudah Seksio Sesaria di PT. Bio Farma (Ferrrero) Bandung.
Abstrak: Seksio sesaria adalah suatu tindakan bedah yang dilakukan untuk mengeluarkan fetus sebelum dilahirkan secara alami dan merupakan tindakan operasi klinik umum dan biasa dilakukan pada satwa primata. Dalam rangka produksi vaksin Polio, PT. Bio Farma Bandung perlu melakukan kegiatan seksio sesaria untuk mendapatkan ginjal fetus monyet ekor panjang berumur 110- 120 hari sebagai bahan baku media biakan produksi vaksin Polio Oral Trivden. Dengan cara ini media biakan ini dapat terhindar dari cemaran mikroorganisme lain yang dapat menyebabkan CPE (Cytopatic Effect).

Judul: Pertambahan bobot badan dan kondisi kesehatan monyet ekor panjang bunting di PT Bio Farma Persero
Abstrak: Monyet Ekor Panjang (Macaca fascicularis) adalah hewan yang memiliki kedekatan filogenetik dengan manusia sehingga sering dipergunakan dalam penelitian biomedis. Belum berhasilnya eradikasi poliomyelitis di dunia menyebabkan terjadinya peningkatan kebutuhan terhadap vaksin Polio. Pertambahan bobot badan (PBB) dan kondisi kesehatan M. fascicularis sebagai bahan baku dalam produksi vaksin Polio turut menentukan kualitas dan kuantitas vaksin yang dihasilkan. Penelitian ini bertujuan untuk mempelajari PBB dan kondisi kesehatan M. fascicularis bunting di penangkaran PT. Bio Farma (Persero). Sembilan ekor M. fascicularis bunting digunakan dalam penelitian ini. Pakan yang diberikan merupakan kombinasi dari monkey chow, jambu biji, pepaya, dan pisang kepok dengan formulasi tiga taraf kadar protein (17.19%, 12.91%. dan 8.60%). Masing-masing taraf kadar protein diberikan kepada tiga monyet. Tiga ekor M. fascicularis digunakan sebagai kontrol untuk masing-masing taraf. Pengaruh ketiga taraf pakan ini diolah dengan Analysis of Variance (ANOVA) menggunakan perangkat lunak Minitab. Obyek yang diberikan pakan dengan taraf protein tertinggi menunjukkan konsumsi protein tertinggi (16.28±0.62%) dengan efisiensi pakan tertinggi pula (94.72±3.60%). Hal ini berdampak terhadap total PBB yang tinggi (0.61 kg) serta rata-rata bobot fetus yang tinggi (0.35kg). Obyek kontrol menunjukkan pola konsumsi dan total PBB yang sama. Selain itu, kondisi kesehatan monyet diukur dengan parameter kadar total protein plasma dan hemoglobin. Kadar total protein plasma tertinggi pada obyek bunting dicapai oleh obyek dengan pakan bertaraf protein tertinggi. Hal ini berarti balıwa pakan perlakuan ini merupakan pakan yang paling efisien ditinjau dari ketersediaan protein yang siap dimetabolismekan di sel atau jaringan tubuh. Seluruh obyek penelitian mengalami penurunan kadar hemoglobin darah sebagai indikasi terjadinya anemia nutrisi selama kebuntingan, kecuali obyek bunting dengan perlakuan taraf protein 12.91%.

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
