Judul: Study on Histopathology of Duodenum and Pancreas broiler  chickens fed with Essential Oil enriched diet
Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh pemberian essential oil kombinasi minyak kayu putih (Eucalyptus sp.), minyak lavender (Lavandula sp.), dan minyak pinus (Pinus sp.) sebagai imbuhan pakan terhadap organ pencernaan ayam broiler. Sebanyak delapan ekor ayam broiler berumur tiga puluh lima hari yang digunakan, empat ekor sebagai kontrol, dan empat ekor diberikan pakan yang telah diperkaya essential oil. Pemberian essential oil pada penelitian ini memberikan efek yang cukup baik pada organ pencernaan, duodenum pada kedua kelompok lapisan tunika mukosa dan lapisan submukosa dalam kondisi normal. Tidak terlihat adanya lesio, hanya terlihat adanya pelepasan vili usus yang sedang beregenerasi. Sementara pada organ pankreas kelompok yang diberikan essential oil, tidak tampak adanya perubahan para sel-sel asinar tetapi meningkatnya sel pada pulau langerhans yang berperan penting dalam pertumbuhan otot ayam broiler.

Judul: Pemberian Minyak Kelapa Sawit dan Minyak Ikan Lemuru dalam Ransum Terhadap Profil Darah dan Persentase Organ Dalam Ayam Broiler
Abstrak: Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian minyak kelapa sawit dan minyak ikan lemuru terhadap profil darah dan persentase organ dalam ayam broiler. Penelitian ini menggunakan 200 ekor day old chick (DOC) broiler strain Ross yang dibagi dalam 4 perlakuan dan 5 ulangan. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan perlakuan P0 = ransum mengandung minyak kelapa sawit 3% dan minyak ikan lemuru 0%, P1 = ransum mengandung minyak kelapa sawit 2% dan minyak ikan lemuru 1%, P2 = ransum mengandung minyak kelapa sawit 1% dan minyak ikan lemuru 2%, P3 = ransum mengandung minyak kelapa sawit 0% dan minyak ikan lemuru 3%. Data yang diperoleh dianalisis menggunakan analisis varians (Anova) dan dilakukan uji lanjut Duncan. Peubah yang diamati adalah profil darah, persentase bobot organ dalam, persentase bobot saluran pencernaan dan panjang relatif saluran pencernaan. Hasil penelitian menunjukkan bahwa perlakuan tidak berpengaruh nyata (P>0.05) terhadap jumlah hematokrit, eritrosit, leukosit, dan deferensiasi leukosit (monosit, eosinofil, basofil), persentase bobot jantung, ginjal, empedu, pankreas, bursa fabricius, thimus, proventrikulus, gizzard, panjang relatif duodenum, persentase bobot dan panjang relatif jejunum, ileum, sekum, serta kolon. Pemberian minyak ikan lemuru 3% berpengaruh nyata (P<0.05) meningkatkan nilai hemoglobin, diferensiasi leukosit (heterofil dan limfosit), persentase bobot hati, persentase bobot limfa, serta menurunkan persentase bobot duodenum dan nilai rasio H/L. Disimpulkan bahwa pemberian ransum mengandung minyak ikan lemuru 3% dalam ransum memberikan dampak positif terhadap profil darahm ayam broiler, dapat meningkatkan kadar hemoglobin, limfosit, dan menurunkan tingkat stress dari taraf tinggi ke taraf rendah., The purpose of this study was to evaluate the effect of giving palm oil and lemuru fish oil on the blood profile and the percentage of internal organs in broiler chickens. This study used 200 Ross broilers day old chick (DOC) is divided into 4 treatments and 5 replications. This research used a completely randomized design (CRD), where the treatments level of palm oil and lemuru fish oil were respectively P0 = rations containing 3% palm oil and 0% lemuru fish oil, P1 = rations containing 2% palm oil and 1% lemuru fish oil, P2 = rations containing 1% palm oil and 2% lemuru fish oil, P3 = rations containing 0% palm oil and 3% lemuru fish oil. The data obtained were analyzed using analysis of variance (Anova) and Duncan's further test was carried out. Some of the observed variables included blood profile, percentage of internal organ weight, percentage of digestive tract weight and relative length of digestive tract. The results showed that the treatment had no significant effect (P>0.05) on the number of hematocrits, erythrocytes, leukocytes, and leukocyte differentiation (monocytes, eosinophils, basophils), the percentage of weight of the heart, kidneys, bile, pancreas, bursa of Fabricius, thymus, proventiculus, gizzard, relative length of duodenum, percentage of weight and relative length of jejunum, ileum, cecum, and colon. Giving 3% lemuru fish oil significantly (P<0.05) increased hemoglobin value, leukocyte differentiation (heterophile and lymphocyte), liver weight percentage, spleen weight percentage, and decreased duodenal weight percentage and H/L ratio value. It was concluded that the provision of rations containing 3% lemuru fish oil in the ration had a positive impact

Judul: The Construction of Greedy SVP LLL Algorithm
Abstrak: A lattice is a set of all integer linear combination of a set of linearly independent vectors in ℝ𝑛���. The independent vectors are called bases of lattice. Any lattice can be generated from many bases, and these bases have the same cardinality. In the lattice, the most fundamental and renowned problem is the Shortest Vector Problem (SVP). SVP is a tracking problem of the shortest nonzero vector in a lattice with equivalent bases. In two dimensions, SVP problem has resolved exactly by Gauss’ algorithm. When the lattice dimension is higher than two, A.K. Lenstra, H.W. Lenstra and L. Lovasz gave a LLL algorithm to compute approximation of nonzero shortest vector in the lattice. Reduced bases solution obtained from LLL algorithm still be an approximation and has polynomial running time of arbitrary dimension which large enough. In 1994, Schnoor and Euchner modified this LLL algorithm as a new variant which later was named deep insertion LLL algorithm. This algorithm is a modified version of the LLL algorithm to the terms of the exchange step to improve the accuracy of output of LLL reduced bases and applying it to the subset sum problem. The purpose of this research are: (1) Reconstruct the LLL algorithm and deep insertion LLL algorithm using a geometric approach. (2) Construct a greedy SVP LLL algorithm. (3) Implement the three algorithms in a symbolic programming language, and evaluate them experimentally. A bases ℬ=[𝐛���1,𝐛���2,…,𝐛���𝑛���] in ℝ𝑚��� is called reduced LLL with parameter 𝛿��� if satisfies: (a) |𝜇���𝑗���𝑖���|≤12, for every integer 𝑖���,𝑗��� with 1≤𝑖���<𝑗���<𝑛���. (b)𝛿���‖𝜋���𝑗���(𝐛���𝑗���)‖2≤‖𝜋���𝑗���(𝐛���𝑗���+1)‖2, for 𝑗���=1,2,…,𝑛���−1,where 𝛿��� is a reduced parameter of real numbers with 14<𝛿���<1. The first requirement is the reduced basis 𝛿��� must “nearly orthogonal” and in its computation case, this requirement can be reached out by using the Gram-Schmidt’s orthogonalization. While the second requirement is called exchange step, or used to called as Lovasz condition. By using both of these requirements, then they establish the LLL algorithm. Then, Schnoor and Euchner modify the LLL algorithm based on the requirements of the exchange step called the deep insertion LLL algorithm, where the exchange step is based on the comparison of the projected vector in orthogonal complement [𝐛���1,𝐛���2,…,𝐛���𝑘���−1]⊥ after j-th reduction. To construct greedy SVP LLL algorithm, the requirements of the exchange step is based on purely by comparing norm of lattice 𝐛���𝑗��� with norm lattice 𝐛���𝑖��� for 𝑖���=1,2,3…,𝑗���−1. The process of insertion reduced vector after the exchange step also has done greedily. Then, we calculate the number of arithmetic operation in greedy SVP LLL algorithm for further analysis. The result of our exprimentation for three algorithms on the certain matrix size shows that the running time of the three algorithms increases propotional to the size of the matrix. The result also shows that by using 𝛿���=34 for the LLL algorithm and the deep insertion LLL algorithm, and the greedy SVP LLL algorithm which is a new variant made by using no parameter of 𝛿���, outperform of the other of two previous algorithm in terms of speed with the same output.
