Abstrak: Kota Bogor merupakan pintu gerbang Propinsi Jawa Barat, berjarak 60 Km dari Jakarta sebagai Ibu Kota Negara Republik Indonesia, dan 120 Km dari Bandung sebagai Ibu Kota Propinsi Jawa Barat. Kota Bogor sering dijuluki sebagai kota hujan karena curah hujan di sini sangat tinggi sekitar 3000 hingga 4000 mm per tahun. Disamping kota jasa yang nyaman dengan masyarakat madani dan bersahabat, Kota Bogor dalam mengembangkan perekonomian masyarakat menitik beratkan pada jasa yang mengoptimalkan pemanfaatan sumber daya yang ada. Terbukti dengan beragam objek wisata dan potensi lainya yang dimiliki Kota Bogor, diantaranya objek wisata ilmiah yang bertaraf internasional, wisata alam, olah raga, budaya, cinderamata, aneka makanan khas, wisata kuliner, pusat-pusat perbelanjaan serta kegiatan pariwisata dan budaya dapat disaksikan di kota Bogor. Berkembangnya jenis restoran di Kota Bogor merupakan reaksi dari beragamnya jenis makanan yang terus berinovasi di Kota Bogor. Masyarakat sebagai konsumen yang cerdas semakin menuntut adanya pemenuhan kebutuhan pangan yang berkualitas, terjangkau, dan praktis dari sisi penyajian maupun citarasa.

Judul: Analisis Tingkat Kepuasan Konsumen Rumah Makan Bebek Gendut Di Kota Bogor
Abstrak: Food is one of a human basic need and become major element in the life of peoples. Therefore, right to food is most important in human rights. To full filling their food needs, most peoples not only consume it, but also kind of the food be a part of their life style. Bebek Gendut is one of a restaurant in Bogor. This restaurant serves a variant duck meet with their special caracteristic flavor.

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
