Judul: Sectoral Effects Of Monetary Policy
Abstrak: The purposes of this study are three folds: (1) identifying which channels are effective for transmission of monetary policy; (2) assessing whether the transmission mechanisms at industry level are consistent with that at aggregate level; and (3) explaining why and how a channel becomes effective. The analyses are facilitated impulse response function (IRF) derived from a vector autoregression (VAR) model. Three channels are identified in this study: interest rate, real credits and exchange rate channels. The IRF results show that exchange rate is the only effective channel in affecting aggregate output and at least in five industries (the manufacturing industry; the construction industry; the trade, hotel, and restaurants industry; the transport and communication industry; and the finance, real estate, and business services industry). Meanwhile, the other two channels are not effective at aggregate and all industry. This finding suggests that there is some form of consistency between aggregate effects and industry effects. Moreover, the effect of real depreciation tend to be contractionary and thus supporting the idea of Krugman and Taylor (1976) among others. Output contraction seems to be associated with inflationary effect of the depreciation. This is a truly Keynesian type demand side story: following a real currency depreciation, purchasing power tends to weaken which then soaks the aggregate demand.

Judul: Impact of the monetary policy instrument on indonesian economy : a monetary transmission mechanism channel analysis
Abstrak: The purpose of this research is to explore the channel of transmission monetary policy mechanism in Indonesian monetary system. The objectives of this research are (1) to describe monetary transmission mechanism channel roles and intermediation function of banking sector to Indonesian economic performance, (2) to analyze monetary policy instrument changes in each monetary transmission mechanism channel that affect Indonesian economic performance effectiveness, and (3) to evaluate monetary transmission mechanism channel effectiffness to Indonesian performances economy. Macroeconometric monetary transmission mechanism model that consists of 18 simultaneous equations and 4 identity equations and simulation conducted to evaluate 7 different scenarios of monetary transmission mechanism channels are interest rate channel, balance sheet channel, bank lending channel, expectation channel, exchange rate channel and direct monetary channel in 4 periods, the pre crisis, the crisis, the transition and the forcast. Monetary policy instruments: interest rate, minimum reserve requirement, money supply, investment, SBI rate, consumer price index and base money become prime monetary variables which have strong influence to exchange rate, inflation rate and product domestic bruto as the performances of the Indonesian economy indicators.

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.
