Judul: Pengaruh Pemberian Dekstrosa Sebelum dan Setelah Transportasi Terhadap, Respon Fisiologis, Penyusutan Bobot Badan dan Tingkah Laku Domba
Abstrak: Tansportasi ternak merupakan kegiatan yang sangat penting bagi peternak untuk mendistribusikan hasil ternaknya ke daerah konsumen. Berbagai masalah ditemui peternak dalam proses pendistribusian, seperti stres yang meyebabkan penurunan bobot badan pada ternak yang bisa dilihat melalui respon fisiologis dan tingkah lakunya. Penelitian ini bertujuan untuk mengkaji pengaruh pemberian dekstrosa sebelum dan setelah transportasi terhadap respon fisiologis, tingkah laku, dan masa rekondisi domba jonggol. Penelitian ini menggunakan domba jonggol betina sebanyak 24 ekor degan rataan bobot badan 18,44±3,32 kg yang dibagi dalam 2 perlakuan, yaitu domba kontrol dan domba yang diberikan dekstrosa sebanyak 0,24 g kg-1 bobot badan per hari selama 5 hari sebelum transportasi dan pada masa rekondisi. Transportasi dilakukan selama 11 jam 15 menit pada siang hari. Data dianalisis menggunakan uji T antara kontrol dan perlakuan masing-masing dengan 12 ulangan. Hasil menunjukkan bahwa pada penyusutan respon fisiologis, tingkah laku, dan penyusutan bobot badan domba perlakuan tidak berbeda nyata (P>0,05) antar perlakuan, namun menunjukkan hasil yang berbeda nyata (P<0,05) pada waktu yang diperlukan untuk mencapai bobot semula (rekondisi). Rataan masa rekondisi domba perlakuan adalah 3,50±0.67 hari lebih pendek dari domba kontrol sebesar 6,42±1,00 hari. Dapat disimpulkan bahwa pemberian dekstrosa dapat mempercepat masa rekondisi domba setelah transportasi., Transportation is a very important activity for breeders to distribute their livestock products to consumption areas such as urban areas. Many problems are encountered by breeders during the distribution process such as stress which causes a decrease in body weight in their livestock and can be seen from their physiological and behavioral responses. This study aimed to examine the effect of dextrose before and after transportation on physiological responses, behavior and period of recovery of sheeps. This study used 24 female jonggol sheeps with an average body weight 18,44±3,32 kg which was divided into 2 treatments, namely control or untreated sheep and sheep that were given dextrose as much as 0,24 g kg-1 body weight per day for 5 days before transportation and during the recovery period until their body weight returned. Transportation is carried out for 11 hours 15 minutes. during the day. Data were analyzed using the T test between control and treatment with 12 repetitions for each. The results showed that the physiological response, behavior and weight loss of dextrose treated sheep were not significantly different (P>0,05) between treatments while the treated sheep showed significantly different results (P<0,05) at the time it takes to reach its original weight (recovery). The mean time of recovery with dextrose was 3,50±0,67 days and control was shorter 6,42±1,00 days. It can be concluded that dextrose can accelerate the recovery period of sheep after transportation.

Judul: Pengaruh Pemberian Minyak Kelapa dan Dextrose terhadap Respon Fisiologis dan Bobot Badan Domba Ekor Tipis Sebelum Transportasi
Abstrak: Transportasi ternak menyebabkan stres yang berakibat pada respon fisiologis dan penyusutan bobot badan ternak. Penelitian ini bertujuan menganalisis pemberian minyak kelapa dan dextrose pada domba ekor tipis sebelum transportasi. Penelitian ini menggunakan 9 ekor domba ekor tipis betina umur 8-12 bulan dengan rataan bobot badan 14,61±2,50 kg. Penelitian ini menggunakan Rancangan Acak Kelompok dengan 3 perlakuan yaitu kontrol, pemberian minyak kelapa sebanyak 4% dari bahan kering konsentrat yang diberikan, dan pemberian dextrose sebanyak 2,24 g kg-1 bobot badan dan dikelompokkan menjadi 3 berdasarkan bobot badan ringan, sedang, dan berat. Data dianalisis dengan Rancangan Acak Kelompok dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan bahwa pemberian minyak kelapa dan dextrose tidak berbeda nyata terhadap penyusutan bobot badan dan respon fisiologis, tetapi berbeda nyata terhadap lama rekondisi yaitu lama rekondisi perlakuan minyak kelapa lebih cepat dibandingkan perlakuan kontrol dan dextrose. Simpulan bahwa minyak kelapa yang diberikan pada domba ekor tipis dapat mempercepat masa rekondisi bobot badan domba., Livestock transportation causes stress which results in physiological responses and weight loss of livestock. This study aimed to analyze the administration of coconut oil and dextrose to thin-tailed sheep before transportation. This study used 9 female thin tailed sheep aged 8-12 months with an average body weight of 14,61±2,50 kg. This study used a Randomized Block Design with 3 treatments namely control, administration of coconut oil as much as 4% of the dry matter concentrate given, and administration of dextrose as much as 2,24 g kg-1 body weight and grouped into 3 based on body weight light, medium, and heavy. Data were analyzed by Randomized Block Design followed by Duncan's test. The results showed that the administration of coconut oil and dextrose was not significantly different to body weight loss and physiological response, but significantly different to the length of reconditioning, namely the length of reconditioning of coconut oil treatment was faster than the control and dextrose treatment. The conclusion is that coconut oil given to thin-tailed sheep can accelerate the reconditioning period of the sheep's body weight.

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
