Judul: Pengkonstruksian Bidirected Overlap Graph Untuk DNA Sequence Assembly
Abstrak: DNA sequencing technologies dapat digunakan untuk memecah gen bakteri menjadi jutaan potongan kecil yang disebut reads. Namun demikian, reads tersebut perlu disambung menjadi contigs agar dapat digunakan. Terdapat 2 metode untuk menyambungkan reads. Yang pertama dengan menggunakan overlap layout consensus (OLC) dan yang lainnya dengan menggunakan de Bruijn graph. Hal penting dalam metode OLC adalah bagian overlap dari masing-masing reads. Pada penelitian ini dikembangkan sebuah sistem untuk membuat bidirected overlap graph yang nantinya akan menghitung berapa jumlah reads yang saling overlap satu sama lain. Suffix array digunakan untuk menentukan fase/bagian overlap dari setiap reads dengan mengindeks setiap suffix dari reads. Waktu adalah parameter penting dalam DNA assembly karena DNA assembly membutuhkan banyak waktu. Untuk mengurangi waktu dilakukan perubahan dari masing-masing suffix dan prefix menjadi suatu nilai tertentu yang bersifat tunggal dan mencari overlap dengan membandingkan setiap reads. Cara ini memberikan dampak positif daripada perbandingan dengan menggunakan string. Perbandingan waktu yang diperlukan antara perbandingan angka dan perbandingan string cukup signifikan. Untuk 2000 dan 5000 reads, sistem dapat memberikan hasil 100% akurat untuk jumlah node dan edge

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.

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.
