Judul: Pengaruh Kepadatan Transportasi terhadap Respon Fisiologis dan Penyusutan Bobot Badan Domba Ekor Tipis.
Abstrak: Kepadatan transportasi merupakan salah satu faktor penyebab stres pada domba. Penelitian ini dilakukan untuk mengkaji pengaruh perlakuan kepadatan domba saat ditransportasikan terhadap tingkat stres yang akan dialami domba. Penelitian ini menggunakan 24 ekor domba betina ekor tipis dengan umur I0. Domba dibagi menjadi dua kelompok dengan 2 kali ulangan transportasi. Perlakuan yang digunakan terdiri dari 2 macam yaitu kepadatan pengangkutan saat transportasi sebesar 0.08 m2 ekor-1 dan 0.17 m2 ekor-1. Peubah yang diamati adalah penyusutan bobot badan, respon fisiologis (denyut jantung, laju respirasi, dan suhu rektal), metabolit serta profil hematologi darah. Data dianalisis dengan menggunakan uji T. Penyusutan bobot badan tidak berpengaruh nyata terhadap perbedaan kepadatan pengangkutan saat transportasi (P>0.05). Hasil respon fisiologis menunjukkan bahwa perlakuan kepadatan terhadap denyut jantung dan respirasi memiliki pengaruh yang nyata (P<0.05). Kepadatan pengangkutan saat transportasi berpengaruh nyata terhadap glukosa darah, hematokrit, basofil, eosinofil, limfosit, neutrofil, dan rasio neutrofil dan limfosit (P<0.05). Kesimpulan dari penelitian ini bahwa kepadatan transportasi 0.08 m2 ekor-1 mengakibatkan tingkat stres domba yang lebih tinggi selama transportasi 6 jam.

Judul: Effect of Density on Physiological Responses and  Performance of Local Sheep on Long Distance Transport
Abstrak: Pengangkutan domba menjadi faktor yang tidak dapat dihindari dalam rantai pasok dan kepadatan menjadi salah satu penyebab stres selama transportasi. Penelitian bertujuan menganalisis pengaruh tingkat kepadatan selama transportasi terhadap respon fisiologis, penyusutan bobot badan, dan durasi rekondisi domba lokal, serta analisis biayanya. Penelitian menggunakan 10 ekor domba lokal betina dewasa. Penelitian dilakukan dengan mengangkut domba dengan kepadatan 0,18 m2 ekor-1 dan 0,24 m2 ekor-1 dengan transportasi jarak jauh berdurasi 11 jam 30 menit. Variabel yang diamati meliputi respon fisiologis (suhu rektal, denyut jantung, dan laju respirasi), susut bobot, durasi rekondisi, dan analisis biaya. Data dianalisis menggunakan Uji T berpasangan untuk menilai kondisi domba sebelum dan setelah perlakuan dan Uji T tidak berpasangan untuk membandingkan rataan kedua kepadatan. Domba mengalami stres akibat transportasi ditandai dengan perubahan yang signifikan pada respon fisiologis dan susut bobotnya. Tingkat kepadatan tidak mempengaruhi perubahan suhu rektal, denyut jantung, laju respirasi, susut bobot, dan durasi rekondisi domba lokal. Domba yang diangkut menggunakan tingkat kepadatan 0,18 m2 ekor-1 lebih efisien secara ekonomi karena penggunaan biaya yang lebih rendah., Sheep transportation is an unavoidable factor in the supply chain and density is one of the stressors during transportation. The aim of this study was to analyse the effect of density level during transportation on physiological responses, body weight loss, recovery of local sheep, and cost analys. The study used 10 female and mature local sheep. The study was conducted by transporting sheep with densities of 0,18 m2 head-1 and 0,24 m2 head-1 with long journey transport of 11 hours 30 minutes duration. The observed variables included physiological responses (rectal temperature, heart rate, and respiratory rate), weight loss, recovery, and cost analys. The data were analyzed using the paired T test to analyse sheep condition before and after the treatment and 2 sample T test to compare of both densities. Sheep experienced stress due to transportation characterized by significant changes in physiological responses and body weight lost. Density level didn’t affect changes in rectal temperature, heart rate, and respiratory rate, weight loss, and recovery duration of local sheep. Sheep that transported by density level 0,18 m2 head-1 economically are more efficient with lower cost.

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
