Judul: Studi pengaruh infeksi Trypanosoma evangi pada gambaran darah dan beberapa biokimia darah domba muda lokal
Abstrak: Penelitian ini bertujuan untuk mengetahui gambaran darah dan beberapa biokimiawi darah domba lokal yang dilakukan secara buatan. 20 ekor domba l oka l yang berumur 6 sampai 7 bulan dengan berat badan rata-rata 12,4 kg dibagi menjadi 4 kelompok perlakuan (A, B, C dan D), masing-masing kelompok terdiri dari 5 ekor. Perl akuan terdiri dari inokulasi dengan 5 x 10 5 , 1 x 10 6 dan 1 ,5 x 10 6 T. evansi, sedangkan kelompok D sebagai kontrol tidak diinokulasi. t/ Contoh darah diambil tiap 3 hari selama 4 minggu, masingmasing sebelum inokulasi dan selanjutnya pada hari ke 3, 6, 9, 12, 15, 18, 21, 24 serta 27 setelah diberi perlakuan. Peubah yang diamati adalah banyaknya eritrosit, nilai PCV, kadar Hb, jumlah lekosit dan diferensiasinya, kadar protein total, albumin, glukosa, LOH dan asam laktat. Terhadap parasitemia, dilakukan pemeriksaan darah secara natif dan jumlah parasit dari masing-masing domba dihitung. Hasil penelitian ini menunjukkan bahwa domba yang diinokulasi T. evansi menyebabkan penurunan total eritrosit, nilai PCV serta kadar Hb, sedangkan jumlah lekosit dan persenrase netrofil terjadi peningkatan pada awal infeksi lalu secara bertahap menurun. Persentase limfosit dan monosit juga meningkat, tetapi eosinofil tidak mengalami perubahan yang berarti. Kadar protein total, laktat dehidrogenase (LDH) dan asam laktat juga meningkat, tetapi peningkatannya berfluktuasi dan sampai akhir pengamatan kadarnya selalu lebih tinggi dari domba kelompok kontrol. Sedangkan kadar albumin dan glukosa darah menurun. Semakin banyak inokulasi T. evansi semakin cepat ditemukan parasit di dalam darah. Parasitemia berfluktuasi, jumlah parasit dari masing-masing domba sedikit (1+) dan periode parasitemianya berlangsung hanya 1 - 2 hari, selanjutnya parasit menghilang di dalam darah dan muncul kembali setelah 3 - 6 hari kemudian dengan jumlah parasit semakin lama semakin menurun. ...

Judul: The red blood cells profile of infected  javanese thin  tailed sheep  with  haemonchus  contortus  larvae  infective
Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh derajat infeksi H. contortus terhadap gambaran jumlah sel darah merah, kadar hemoglobin dan nilai hematokrit pada domba ekor tipis. Sebanyak 20 ekor domba ekor tipis jantan berumur 6–8 bulan dikelompokkan menjadi lima kelompok yaitu kelompok kontrol tidak diinfeksi larva infektif (L 3 ) dan kelompok infeksi L3 dengan dosis 500 L3 , 1000 L3 , 2000 L3 dan 4000 L3 . Sampel darah dan tinja dikumpulkan sekali setiap minggu selama tujuh minggu setelah infeksi. Sampel darah diperiksa untuk mengetahui jumlah sel darah merah, kadar hemoglobin dan nilai hematokrit. Sampel tinja juga diperiksa untuk menghitung jumlah telur tiap gram tinja. Hasil penelitian menunjukkan bahwa dosis infeksi L 3 mempengaruhi nilai hematokrit (P<0.05), namun tidak mempengaruhi jumlah sel darah merah dan kadar hemoglobin (P>0.05). Jumlah telur tiap gram tinja (TTGT) berkorelasi negatif namun lemah dengan jumlah sel darah merah, kadar hemoglobin dan nilai hematokrit (P<0.05; R<0.50)., This research was conducted to investigate the effect of H. contortus infection to red blood cell profil of Javanese thin tail sheep. The total of 20 males of Javanese thin tailed sheep age 6-8 months were grouped into five groups namely not infected control group and infective group of 500 L 3, 1000 L 3, 2000 L 3 and 4000 L 3 . The samples of blood and fecal were collected weekly for seven weeks. The blood samples were examined to determine the total of red blood cells, hemoglobin levels and pack cell volume, whereas fecal samples to determine egg per gram. The results showed that the infection dose had the effect to pack cell volume, but the total of red blood cells and hemoglobin levels were not significantly different. The amount of egg per gram were negatively correlated with the red blood cells, hemoglobin level and pack cell volume.

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
