Judul: Analisis persepsi konsumen terhadap endorser iklan di televisi dan hubungannya dengan keputusan pembelian (Kasus: Iklan Kuku Bima Ener-G)
Abstrak: Aktifitas masyarakat yang terus meningkat, permintaan akan produkproduk minuman suplemen juga terus bertambah. Permintaan pasar terus meningkat tajam, tahun 2005 volume pasar minuman energi menyerap 314 juta liter atau 563 sachet dengan pertumbuhan 12 persen dengan peningkatan jumlah produksi dari tiga pabrik dengan lima item produk menjadi 12 pabrik dengan 50 item produk. Persaingan pasar minuman energi cukup ketat, Extra Joss selaku pemimpin pasar dalam beberapa tahun terakhir mengalami penurunan, posisinya direduksi oleh Kuku Bima Ener-G, strategi yang dilakukan yaitu dengan mengoptimalkan unsur 4P (Product, Price, Placement, Promotion) dengan prestasi antara lain: meraih delapan nominasi penghargaan, dan dibeberapa daerah menempati posisi pertama. Strategi pemasaran yang dilakukan Kuku Bima Ener- G adalah dengan promosi, salah satu bentuk promosi Kuku Bima Ener-G adalah dengan mengunakan tokoh yang berbeda dari berbagai latar belakang sebagai endorser dalam iklannya, mulai dari Mbah Maridjan, Chrish Jhon, Ade Ray, Vega Darwanti Ngatini, Doni Kesuma, Rieke Diah Pitaloka. Hasilnya, Kuku Bima Ener-G meraih prestasi pejualan sampai 500 persen, dan penampilan Mbah Marijan diperkirakan memberikan kontribusi 250 persen.

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
