Judul: Studi identifikasi golongan darah dan kemungkinan hubungannya dengan warna rambut pada kucing kampung(Felis familiaris)
Abstrak: Penelitian ini dilakukan untuk mengetahui frekuensi persebaran golongan darah A, B dan AB pada kucing kampung di Indonesia dengan menggunakan 50 ekor kucing kampung yang diperoleh dari daerah Bogor dan Bekasi. Penelitian juga dilakukan untuk melihat ada tidaknya kemungkinan hubungan antara golongan darah dengan kemunculan warna rambut kucing. Pemeriksaan golongan darah kucing dilakukan dengan metode antibodi monoklonal Shigeta. Hasil penelitian menunjukkan bahwa semua kucing kampung yang diteliti bergolongan darah A dan tidak diperoleh tanda-tanda adanya hubungan antara golongan darah dengan warna rambut. Pemunculan golongan darah A kemungkinan disebabkan antara lain oleh kandungan genotipe dari golongan darah. Warna rambut kucing pada penelitian ini dapat dibagi menjadi sembilan kelompok warna berdasarkan pola warna tunggal, kombinasi dua warna dan kombinasi tiga warna. Berdasarkan hasil penelitian dan studi literatur, tidak ada hubungan antara golongan darah dengan warna rambut. Warna rambut terkait dengan gen pengontrol warna, gen pengontrol pola warna dan gen pengontrol ekspresi warna yang terdapat pada kromosom autosom dan atau kromosom seks (sex-linked).

Judul: The daily behavior of wild domestic cats (Felis domesticus) and its correlation to hair colour patterns
Abstrak: Kucing domestik (Felis domesticus) merupakan salah satu mamalia yang hidup berdampingan dengan manusia. Mengacu dari penelitian terdahulu, perilaku kucing memiliki korelasi dengan pola warna rambutnya. Penelitian ini bertujuan mempelajari hubungan antara tipe pola warna rambut dengan perilaku harian kucing domestik liar. Sebanyak delapan kucing domestik liar betina yang berada di dalam area kampus IPB University digunakan dalam penelitian ini. Pengambilan data dilakukan menggunakan metode Focal Animal Sampling untuk mencatat frekuensi perilaku satu individu berdasarkan durasi waktu tertentu. Perilaku yang diamati dibagi dalam tiga kategori yaitu, perilaku afiliatif, pertemuan negatif, dan pemeliharaan diri. Hasil analisis menunjukkan ada keterkaitan antara pola warna rambut dengan perilaku afiliatif. Namun, tidak ada keterkaitan antara pola warna rambut dengan perilaku pertemuan negatif dan perilaku pemeliharaan diri. Hasil tersebut menunjukkan pola warna rambut yang berbeda menghasilkan perilaku afiliatif yang berbeda. Pada kategori perilaku pertemuan negatif dan pemeliharaan diri, pengaruh pola warna rambut tidak berbeda nyata. Kata kunci: belang dua warna, belang tiga warna, focal animal sampling, pola bergaris, pola satu warna, The domestic cat (Felis domesticus) is small mammal that lives alongside humans. Many studies report domestic cats’ behavior correlates with their hair colour patterns. This study aimed to analyse the correlation between various hair colour patterns and wild domestic cats’ daily behavior. As many as eight female wild domestic cats in the IPB University campus were used as objects in this study. Data collection was carried out using the Focal Animal Sampling method to record the frequency of one individual's behavior based on a determined duration of time. The observed daily behavior divided into affiliative, negative encounters, and self-maintenance. Thr results of the analysis obtained show that there’s a correlation between hair colour patterns and affiliative behavior. However, there is no correlation between hair colour patterns, negative encounter behavior, and self-maintenance behavior. These indicate that different hair colour patterns produce different affiliative behaviors. Meanwhile, the effect of the hair colour pattern was insignificant in the category of negative encounter behavior and self-maintenance.

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.
