Judul: Motivasi dan Perilaku Menonton Program Acara Merajut Asa Trans7 pada Petani Desa Citapen, Kabupaten Bogor
Abstrak: This study aimed to asses the correlation between demographic characteristics with viewing motivation, the correlation between social groups affiliation with viewing motivation, the correlation between personality type with viewing motivation, and the correlation between viewing motivation with viewing behavior of watching Merajut Asa Trans7 program. The research sample was farm worker in RW 05 Citapen Village who had seen the program. The results of the study explain that gender associated with integration and social interaction motivation and additional work associated with personal identity motivation. Age, level of education, income levels, family’s size, and the type of personality was not associated with viewing motivation. The level of social group affiliation associated only with information motivation and personal identity motivation, while viewing motivation was not related with viewing behavior of Merajut Asa Trans7 program.

Judul: Hubungan antara Motivasi Menonton dan Keterdedahan Tayangan Orang Pinggiran Trans7 dengan Sikap Prososial Remaja di Pedesaan
Abstrak: Televisi kini telah mampu menjangkau khalayak luas, termasuk masyarakat pedesaan. Penelitian ini bertujuan untuk menganalisis hubungan antara karakteristik remaja di pedesaan dengan motivasi menonton, motivasi menonton dengan keterdedahan program Orang Pinggiran, dan keterdedahan program Orang Pinggiran dengan sikap prososial remaja di pedesaan. Remaja dipilih sebagai unit analisis, sebab masa remaja adalah masa peralihan, ketika individu tumbuh dari masa anak-anak menjadi individu yang memiliki kematangan. Teknik pengumpulan data yang digunakan dalam penelitian ini adalah teknik wawancara dengan menggunakan kuesioner. Hasil penelitian ini menunjukkan bahwa terdapat hubungan antara usia, jenis kelamin, pendidikan terakhir, jenis pekerjaan, tingkat interaksi dengan keluarga, dan tingkat interaksi dengan teman dengan motivasi menonton program Orang Pinggiran dan antara motivasi menonton dengan keterdedahan tayangan tersebut. Selain itu, keterdedahan program Orang Pinggiran berhubungan dengan sikap prososial remaja dalam aspek kognitif dan afektif.

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
