Judul: Evaluasi Manajemen Transportasi Domba Batur serta Pengaruh Jenis Kelamin dan Umur Akibat Transportasi.
Abstrak: Transportasi ternak adalah salah satu cara untuk mendistribusikan produk peternakan dalam penyediaan pemenuhan kebutuhan protein hewani. Kesejahteraan ternak dalam proses transportasi harus diperhatikan karena diduga berpengaruh terhadap kondisi fisiologis selama proses transportasi. Pengaruh ini diduga disebabkan oleh sistem transportasi yang sederhana, tradisional, dan tidak memperhatikan kesejahteraan ternak. Penelitian ini mengkaji tentang evaluasi transportasi ternak di Pasar Ternak Batur dan transportasi yang dilakukan dari Desa Batur menuju IPB Dramaga, Bogor. Perlakuan yang diberikan adalah domba batur sebanyak 21 ekor jenis kelamin (jantan dan betina) dan umur (4 sampai 5 bulan dan 8 sampai 9 bulan). Parameter yang diamati adalah respon fisiologis dan penurunan bobot badan. Hasil penelitian ini menunjukan, pengaruh perbedaan jenis kelamin dan umur terhadap penurunan bobot badan tidak berbeda nyata. Uji yang sama menunjukan bahwa perbedaan jenis kelamin dan umur tidak berbeda nyata terhadap respon fisiologis domba batur (frekuensi pernafasan, suhu rektal, dan denyut nadi). Manajemen transportasi yang baik belum di terapkan oleh masyarakat di Desa Batur.

Judul: Transportasi Ternak Domba Ekor Gemuk Jantan Yang Tidak Diberi Pakan Selama Perjalanan
Abstrak: Sentra konsumsi daging domba di Indonesia masih berpusat didaerah perkotaan sehingga dibutuhkan aktifitas transportasi untuk mendistribusikan ternak tersebut kedaerah konsumsi. Pengiriman domba antar daerah dapat mengakibatkan stress dan penurunan berat badannya. Penelitian ini bertujuan untuk menguji penyusutan bobot badan, perubahan respon fisiologi, analisis biaya transportasi dan kerugian penyusutan bobot badan ternak domba ekor gemuk jantan yang tidak diberi pakan selama perjalanan. Penelitian ini menggunakan ternak domba ekor gemuk jantan sebanyak 157 ekor umur 2 tahun dan bobot rata-rata 20 sampai 24 kg dengan tiga perlakuan (Rute 1= 9 jam 40 menit; Rute 2= 15 jam 30 menit dan Rute 3=19 jam 40 menit). Data performa dan fisiologi diolah menggunakan Analysis of Variance (ANOVA). Hasil penelitian menunjukkan bahwa persentase penyusutan antara Rute 1, Rute2 dan Rute 3 berbeda nyata (P<0.05) dengan penyusutan tertinggi pada Rute 3. Laju respirasi pada Rute 1 nyata lebih tinggi dibanding dengan rute lainnya (P<0.05). Disimpulkan bahwa semakin lama proses transportasi dilakukan maka penyusutan bobot badan domba akan semakin besar.

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
