Judul: Pengaruh Bentuk Fisik Ransum Yang Mengandung Tapioka Terhadap Performans Ayam Pedaging (Broiler)
Abstrak: Penelitian dilakukan di Bagian Ilmu Produksi Ternak Unggas, Fakultas Peternakan, Institut Pertanian Bogor, mulai tanggal 9 Juni sampai dengan 28 Juli 1984. Tujuan penelitian adalah untuk mengetahui pengaruh bentuk fisik makanan dan kadar tapioka dalam ransum terhadap performans ayam pedaging (broiler). Pada penelitian ini digunakan ayam pedaging galur "Indian Rivers" sebanyak 120 ekor jenis kelamin jantan. kandangkan pada kandang berbentuk kotak berukuran 2 x 1 x 0.75 m3 yang disekat menjadi empat bagian dan tiap bagian diisi 5 ekor anak ayam. Ayam mendapatkan perlakuan setelah rataan berat badan 223.01 ± 15.22 gram (KV: 6.8%). Ransum yang digunakan terdiri atas jagung kuning, tepung tapioka varietas SPP, bungkil kedelai, dedak halus, tepung ikan Thailand, minyak kelapa (barko), CaCOz, dan Premix A. Sebagian ransum dijadikan "pellet" dan sebagian lagi dalam bentuk tepung, dan diberikan pada ayam dengan kadar tapioka yang berbeda-beda yaitu B1, B2, dan Bz masing-masing mengandung 0, 20 dan 40 persen tapioka. Parameter yang diukur adalah konsumsi makanan, pertambahan berat badan, berat badan akhir (7 minggu) dan konversi makanan. Rancangan yang digunakan adalah Rancangan Acak Lengkap dengan Pola Faktorial 2 x 3. Faktor pertama adalah 2 bentuk fisik ransum yaitu bentuk "pellet" dan tepung. Faktor kedua ialah tingkatan tapioka dalam ransum berturut-turut 0, 20, 40 persen. Tiap perlakuan terdiri atas 4 ulangan. Hasil analisis statistik menunjukkan bahwa kadar tapioka berpengaruh sangat nyata (P/ 0.01) terhadap pertambahan berat badan, berat badan akhir dan konversi makanan tetapi tidak berpengaruh terhadap konsumsi makanan. Pertambahan berat badan, berat badan akhir dan konversi makanan pada ransum berkadar tapioka 0% sangat nyata (P/ 0.01) lebih baik dari pada ransum berkadar tapioka 20 dan 40 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
