Judul: Performa Domba Lokal dengan Pemberian Pakan Konsentrat Komersial dan Sorinfer pada Taraf yang Berbeda
Abstrak: Performa domba dipengaruhi oleh beberapa aspek seperti manajemen pakan. Penelitian bertujuan mengkaji performa domba lokal dengan pemberian pakan kombinasi sorinfer terhadap performa produksi domba lokal. Domba yang digunakan adalah domba betina lokal betina yang berumur 1-2 tahun (I0- I1) sebanyak 15 ekor dengan rataan bobot awal 19,38±3,11 kg. Penelitian menggunakan 3 perlakuan ransum yaitu konsentrat yang dikombinasikan dengan silase sorinfer dengan rasio P1 75:25, P2 50:50, P3 25:75. Peubah yang diamati adalah konsumsi ransum as feed, bahan kering (BK), protein kasar (PK), energi (TDN), konversi ransum as feed, BK, pertambahan bobot badan (PBB), bobot akhir, serta feed cost per gain (FCG). Data dianalisis kovarian (ANCOVA) menggunakan Statistical Product and Service Solution (SPSS) yang diuji lanjut dengan metode Duncan. Hasil penelitian menunjukkan konsumsi ransum as feed, BK, PK pada perlakuan P1 nyata lebih tinggi (P<0,05) dibandingkan dengan perlakuan lainnya. Nilai TDN, konversi as feed, konversi BK, PBB, dan FCG ketiga perlakuan tidak berbeda nyata (P>0,05). Perlakuan P1 menghasilkan performa domba terbaik berdasarkan konsumsi as feed, konsumsi BK, dan konsumsi PK.

Judul: Performance and Behavior of Local Sheep with Concentrate and Sorinfer Feed Combination in Intensive Rearing
Abstrak: Domba lokal merupakan hasil persilangan dari luar yang telah dikembangbiakkan dan beradaptasi dengan lingkungan di Indonesia. Tujuan dari penelitian ini untuk mengkaji pengaruh pemberian pakan kombinasi sorinfer terhadap performa dan tingkah laku domba lokal UP3J. Penelitian ini menggunakan 25 ekor domba yang dibagi menjadi 5 perlakuan ransum yaitu konsentrat, sorinfer dan rumput odot. Data dianalisis menggunakan (ANOVA), bila terdapat perbedaan nyata, maka diuji lanjut uji Duncan. Hasil penelitian menunjukkan bahwa konsumsi as feed, PBBH, dan bobot akhir perlakuan P5 nyata berbeda (P<0,05) dibandingkan lainnya, sedangkan konsumsi BK P2 berbeda nyata (P<0,05). Konversi as feed dan konversi BK untuk kelima perlakuan sama. Frekuensi ingestive pada perlakuan P5 berbeda nyata (P<0,05) dibandingkan lainnya. Selanjutnya tingkah laku, minum, vokalisasi, dan locomotive pada domba dengan perlakuam P4, dan P2 berbeda nyata (P<0,05) dibandingkan lainnya. Frekuensi resting dari kelima perlakuan menunjukan hasil sama. Performa domba lokal dengan pemberian pakan 100% sorinfer mempunyai performa lebih baik dibandingkan lainnya. Domba lokal dengan pemberian 100% sorinfer mempunyai frekuensi tingkah laku ingestive yang lebih tinggi., Local sheep are the result of crosses from outside that have been bred and adapted to the environment in Indonesia. The purpose of this study was to examine the effect of sorinfer combination feeding on the performance and behavior of UP3J local sheep. This study used 25 sheep which were divided into 5 ration treatments, namely concentrate, sorinfer, and odot grass. Data were analyzed using (ANOVA), if there is a significant difference, then it is further tested by Duncan's test. The results showed that the consumption of as feed, PBBH, and the final weight of the P5 treatment was significantly different (P<0.05) compared to the others, while the consumption of BK P2 was significantly different (P<0.05). The as feed conversion and BK conversion for the five treatments were the same. Ingestive frequency in the P5 treatment was significantly different (P<0.05) compared to the others. Furthermore, behavior, drinking, vocalization, and locomotive in sheep treated with P4 and P2 were significantly different (P<0.05) compared to the others. The resting frequencies of the five treatments showed the same results. The performance of local sheep with 100% sorinfer feed has better performance than others. Local sheep with 100% sorinfer administration had a higher frequency of ingestive behavior.

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
