Judul: Pengoptimuman Alignment Struktur Protein Menggunakan Clique Maksimum
Abstrak: An alignment of protein structures describes the relationship of two types of proteins similarity function. The problems of the protein structure alignments can be identified through the problems of the Contact Map Overlap (CMO). The problems of CMO can be solved by finding a maximum clique in a graph, where vertices and edges represent the amino acids and contacts between any two amino acids respectively. In this paper, the problem of finding maximum cliques is using two main steps, the arranging vertices and edges based on the special properties of the graph and preprocessing vertices. Implementation of the model is done by using the structure of a hypothetical protein.

Judul: Paralellization Multiple Sequence Alignment
Abstrak: Sequence alignment (sequence alignment) is one of the problems in molecular biology that can be solved with the help of computer programs. The purpose of an alignment is to identify similarity region of sequence in Deoxyribonucleic acid (DNA), Ribonucleic acid (RNA), or protein. One of sequence alignment methods is Needleman-Wunsch which includes all sequences in its alignment. The Needleman-Wunsch method has high computational complexity with value of O(n2). Similarly, multiple sequence alignment (MSA) that processes k sequences one by one by using Star Alignment method has complexity of O(k2n2). Therefore, the main problem in MSA using Star Alignment method is computational time. However, the Star Alignment method can still obtain high accuracy. The time consuming problem faced by Star Alignment method can be solved by applying parallel computing technique implemented using multiple computers working together as a network system. This research focuses on finding a faster method to process MSA based on Star Alignment method using parallel computing. The proposed method is implemented using Message Passing Interface (MPI). The evaluation is conducted by calculating speed up. The experiment results show that the paralellization of the Star Alignment method can increase speed up 4-6 times faster than that of using single CPU.

Judul: Efek Asap Rokok pada Tikus (Rattus norvegicus) Bunting terhadap  Tampilan Fisiologis Induk dan Anaknya Setelah Dilahirkan.
Abstrak: Kebiasaan merokok di Indonesia dan beberapa negara berkembang lainnya terus meningkat. Perokok di Indonesia berjumlah 75% yang terdiri atas 60% berasal dari populasi pria dan 15% dari populasi wanita (WHO 2005). Sementara di negaranegara maju kebiasaan merokok justru semakin menurun, hal ini disebabkan karena mereka telah sadar akan bahaya rokok pada kesehatan. Hasil Survei Global Youth Tobacco memperlihatkan bahwa 88% perokok di Indonesia lebih menyukai rokok kretek dan 12% menyukai rokok putih. Kadar tar dan nikotin pada rokok kretek lebih tinggi, dibanding rokok putih. Rokok kretek berpotensi menghasilkan asap yang lebih banyak baik asap arus utama dan arus samping dibandingkan dengan rokok putih. Belakangan ini, bahaya asap rokok tidak hanya difokuskan pada perokok aktif tetapi juga pada perokok pasif. Perokok pasif mempunyai peluang yang sama bahkan lebih tinggi mendapatkan penyakit dibandingkan perokok aktif. Secara umum gangguan asap rokok terhadap kesehatan manusia dapat terjadi mulai pada fase janin, anak-anak sampai pada orang dewasa. Gangguan kesehatan itu antara lain gangguan pernafasan, fertilitas, impotensi, jantung dan kelainan pada janin. Wanita hamil yang sering terpapar asap rokok dapat menyebabkan gangguan kesehatan pada anaknya bahkan sebelum anak dilahirkan (fase janin). Beberapa kelainan atau gangguan asap rokok terhadap janin diantaranya adalah: a) terjadinya keguguran spontan, b) berat badan lahir rendah, c) komplikasi saat melahirkan, dan d) kelainan pada perkembangan saraf.
