Judul: Dampak nilai tukar dan pertumbuhan uang beredar (M2) terhadap inflasi Indonesia periode tahun 2002-2012
Abstrak: Inflation is a phenomenon of rising prices of goods and services in general. Inflation control becomes an important task for the goverment that controlled prices of goods and services in the community. Inflation rate is influenced by domestic and foreign factors. The crisis that comes from foreign such as the 2005 and 2008 impact of high inflation in the country. The purpose of the study is to see the effect of exchange rate and money growth on inflation Indonesia from 2002 until 2012. Method used in this study is Vector Error Correction Model (VECM). The study used quartal time series from quartal 1 on 2002 until quartal 4 on 2012. According to Impulse Response Function test, the results of this study show that exchange rate variable and money growth variable have a positive impact on inflation for the next twenty quarters (5 years). According to Variance Decomposition test shows that money growth variable has a dominant impact than exchange rate variable for the next twenty quarters (5 years).

Judul: Inflasi dan Pertumbuhan Ekonomi: Pendugaan Ambang Batas Inflasi di Indonesia.
Abstrak: High inflation is regarded as a problems in the economy. Indonesia experienced economic collapse as a result of failing to control inflation volatility. This is used as a reason for the current authorities to implement low-inflation policy. The economist argues that low-inflation can promote economic growth faster. In fact, low-inflation policy is not favorable because it interferes the business investment climate. On the other hand the pattern of the inflation and economic growth data in Indonesia is also inconsistent (indicating a positive relationship, negative and neutral). The purpose of this study is to determine the effect of inflation on economic growth, as well as to search inflation threshold in Indonesia in the period 1970- 2012. Using multiple linear regression, this study shows that inflation negatively impacts on economic growth. Inflation threshold identification by Khan and Senhadji model (2001) stated that inflation threshold in Indonesia is 7.11%. While according to Hansen model (1997, 2000), inflation threshold in Indonesia is 9.53%. Based on some model selection criterias, the inflation threshold implied by Hansen model is more apropriate. Inflation has a positive effect on economic growth if the value is less than the thresholds and negative when it exceeds the thresholds. This result supports Chowdhury and Ham (2009) finding who stated that inflation threshold in Indonesia is between 8.5 per cent and 11 per cent. The two studies imply that the central bank should only pursue active policy measures when inflation is above the threshold. Thus, ITF cannot be generalized to all levels of inflation.

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.
