Judul: Relationship between Characteristics and Behaviour of Entrepreneurs and Business Performance Plasma Chicken Farmers in Bogor District (A Case Study on Bogor Merdeka Unggas Plasma Chicken Farmers).
Abstrak: Peranan penting peternakan menyebabkan peternakan menjadi sektor yang diminati pengusaha. Adanya hambatan dan keterbatasan dalam melakukan usaha ternak ayam berdampak pada kinerja usaha peternak. Perlu dilakukan identifikasi kinerja usaha pada peternak kemitraan apakah dalam pola kemitraan dapat meningkatkan kinerja usaha dan kinerja usaha mempunyai hubungannya dengan karakteristik dan perilaku wirausaha yang dimiliki peternak ayam plasma. Tujuan dari penelitian untuk mengukur hubungan karakteristik dan perilaku wirausaha dengan kinerja usaha peternak ayam plasma. Data dikumpulkan dari 32 orang responden peternak ayam plasma di wilayah Kabupaten Bogor. Responden dipilih dengan metode probability sampling melalui pendekatan simple random sampling. Alat analisis yang digunakan korelasi Rank Spearman. Hasil penelitian menunjukkan tidak semua karakteristik dan perilaku wirausaha berhubungan positif dan signifikan dengan kinerja usaha peternak ayam plasma.

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
