Judul: Konsumsi energi minuman berkalori dan kontribusinya terhadap total konsumsi energi pada remaja dan dewasa
Abstrak: The objective of this research was to analyze energy intake from calorie beverages (EICB) and it’s contribution total energy intake of adolescents and adults. The research was carried out throught analyzing a data set of THIRST (The Indonesian Regional Hydration Study) collected in 2008 and 2009 by applying a crossectional study design among 606 adolescents (male and female aged 15-18 yrs) and 594 adults (male and female aged 25-55 yrs) in North Jakarta, West Bandung, Surabaya, Malang, Makasar and Malino. Data processing and analysis were conducted in Bogor in April-July 2011. The results showed that the mean EICB among adolescents was 420 ± 406 kcal/d and emong adults was 450 ± 382 kcal/d, which is 21.2% and 23.4% of the total energy intake (TEI) of adolescents and adults respectively. EICB was moderately associated with TEI of adolescents (r= 0.58, p<0.05 ), of adults (r= 0.51 , p<0.05), and of both adolescents and adults (r= 0.54 and p<0.05). This could be lead to over energy intake, obesity and other possible adverse effects. Further studies are required to analyze causal relationship between EICB and obesity, and other possible adverse effects among Indonesians; while at the same time it is also important to start promoting an advice for healthier and wiser beverages choices.

Judul: Kontribusi minuman dalam kemasan berlabel terhadap tingkat kecukupan energi dan zat gizi pada siswa sekolah dasar dan menengah bina insani di kota Bogor
Abstrak: The objective of this research is to analyze the contribution of drinks to the level of energy and nutrient intake of the primary and high school students at Bina Insani Bogor. Cross-sectional study design method was applied. The data were collected within the period of January to February 2011 at Bina Insani School. The sample taken consisted of three hundreds respondents, consisting of primary, junior high school and senior high school students,100 students each. The results of this study showed that on average, the contribution of drinks consumption towards overall energy and nutrient consumed is 5% among senior high school students, 9% among junior high school students and 9% among primary school students. Another prominent nutrient intake contribution is contribution of vitamin C and calcium. Factors affecting energy, vitamin C and calcium intake contribution are pocket money allocated to buy drinks, volume consumed, and frequency of consumption of drinks.

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.
