Judul: Fenomena Peradangan Kardio-Obesitas Pada Monyet Ekor Panjang (Macaca Fascicularis) Jantan Dewasa Dengan Induksi Diet Obsitogenik
Abstrak: Pola hidup masyarakat dengan konsumsi makanan tinggi kolesterol dan karbohidrat akan meningkatkan resiko sindrom metabolik, seperti obesitas. Obesitas adalah faktor utama penyebab penyakit kardiovaskular dan peradangan yang dapat menyebabkan aterosklerosis serta akumulasi sel-sel radang pada sekitar pembuluh darah. Respon peradangan yang disebabkan oleh kardio-obesitas pada pembuluh darah aorta diteliti pada monyet ekor panjang jantan dewasa (Macaca fascicularis) (n=11) menggunakan standar penilaian kuantitatif histologis. Respons peradangan ini diamati pada monyet obesitas yang disebabkan oleh asupan diet obesitogenik selama 15 bulan (n=9) dibandingkan dengan monyet obesitas yang disebabkan konsumsi pakan monyet dalam jumlah tak terbatas (ad-libitum) (n=2). Fenomena ini bisa digunakan sebagai gambaran mikroskopis kardio-obesitas pada monyet sebagai hewan model penyakit kardiovaskular. Respon peradangan lebih rendah pada monyet yang diberi asupan diet obsitogenik diikuti intervensi nikotin cair dosis rendah selama tiga bulan. Studi kasus ini menunjukkan bahwa nikotin cair dosis rendah memiliki efek hambat pada respon peradangan kardio-obesitas.

Judul: Hipertrofi Kordis pada Monyet Ekor Panjang (Macaca fasicularis) Pasca Obes Induksi Diet Obesitogenik Diikuti Asupan Nikotin
Abstrak: The aim of this study was to examine the evidence of left ventricular hypertrophy of male cynomolgus macaque (Macaca fascicularis) as animal model of human obesity and atherosclerosis. The animals were fed obesitogenic diet for 12 month and treated by per-oral nicotine liquid for 3 month. The objective of this study is exploring the macroscopic aspect of fatty heart enlargement and its compensation. Almost of fifteen samples of hearts showed varies level of fatty deposition and blunted apex. Heart muscle thickening was measured on distal transversal one centimeter’s cutting using caliper with two decimal precision. Relative Wall Thickness (RWT) was measured by calculating Septal Wall Thickness (SWT) that added by Posterior Wall Thickness (PWT) and divided by Left Ventricular Internal Diameter (LVID). All of the heart mostly have concentric type of hypertrophy with elevation of RWT (1.87 ± 1.47 centimeter) compare to the normal one (0,45 centimeter). This RWT has low relations to body weight (r = 0.060) and body mass index (r =0.054). This study refilled that cynomlgous macaque can be developed as animal model of ventricular hypertrophy as a part of alternative solution of ventricular hypertrophy in conjunction with endemic obesity on urban society. This study suggested that the study of nicotine effect on ventricular hypertrophy should be conducted microscopically.

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
