Judul: Bioavailabilitas Kalsium (Ca) dan Zat Besi (Fe) secara In Vitro pada Beberapa Prdouk Komersial Susu Ibu Hamil
Abstrak: Milk is one of animal foodstuffs that commonly consumed by human, because of its complete and higly nutritious substance, including calcium and iron. Mineral deficiencies, such as calcium and iron, remain a major problem in many developing countries including Indonesia especially for pregnant women. Commercial maternal milk product is a sourceof calcium and iron that is potential to be consumed. Some commercial maternal milk products in market offerhigh calcium and iron product. This study used four commercial maternal milk products as samples. The sampleswere selected based on the content of calcium, iron, dietary fiberand prebiotic (FOS and GOS) that are listed on the nutrition fact. Investigation of in vitro bioavailability for calcium and iron was the major objective of this study because the high calcium and iron content in food does not always describe whether the absorbed calcium and iron was also high. The moisture, ashes, protein, calcium, iron, phosphor, dietary fiber, zinc, available total calcium and available total iron contents among the milk product used in this study were significantly different (p<0,05). However, there is no significant relationship between type of product with bioavailability of calcium and bioavailability of iron (p>0,05). Futhermore there is no significant relationship between nutrients contents (fiber, phosphor, zinc, FOS and GOS) and the bioavailability calcium and biovailability iron on the samples. According to this study catogory of bioavailability of calcium and iron in commercial maternal milk productswas high.

Abstrak: Dairy products claimed for high calcium and low fat become more available in the market. The objective of this study was to analyze in vitro bioavailability of calcium in milk products which have been claimed for high calcium and low fat . Two liquid, pasteurized and UHT, and a powdered milk product were used. The survey and sampling were conducted based on predetermined criteria through purposive sampling in several minimarket and supermarket in Bogor area. Each product was tested for the content of moisture, ash, protein, fat, calcium, phosphorus, and also for calcium bioavailability. Total available calcium in each product was also calculated. There were significant difference in moisture content, protein, calcium, phosphor, and total available calcium among the milk products. Ash and fat content of each product were not significantly different. The highest calcium bioavailability was observed product A (64.01%) and the lowest was in product B (28.71%). The result of statistical analysis by ANOVA showed that different processing affected calcium bioavailability of three products (p<0.05). Calcium bioavailability of product A was the highest and the most noticeable different among three products. Levels of protein, fat, calcium, and phosphorus, and the type of milk did not correlate with calcium bioavailability

Judul: Penyusunan Overlap Graph menggunakan Suffix Tree pada DNA Sequence
Abstrak: The DNA sequence assembly is very important in genome analysis. This step aims to reconstruct contigous DNA fragment (contigs) from short fragment by concatenating fragments based on the overlap region among them. This method employs overlap graph for solving the problems. In this graph, nodes represent fragments and edges represent overlap. This research developed a software for constructing overlap graph using suffix tree. The evaluation was conducted by measuring the number of nodes, number of edges, and the execution time in many values of minimum overlap. The minimum overlap is defined as the minimum length of substring which is considered as the overlap region between two fragments. The evaluation results showed that the number of nodes, the number of edges, and the execution time were increased with the decreasing of the minimum overlap value.
