Judul: The Influence of Macroeconomic Variables on the Indonesian Stock Market Development
Abstrak: Peran pasar modal sebagai sumber pendanaan perusahaan yang berimplikasi bagi perekonomian negara bukan hanya sekedar alternatif tetapi sudah mampu menjadi sumber pendanaan utama. Diperlukan peran yang lebih besar untuk mendorong perkembangan pasar modal Indonesia agar lebih besar dan tahan terhadap berbagai guncangan. Penelitian ini menggunakan metode ARDL-ECM untuk menganalisis pengaruh faktor makroekonomi terhadap perkembangan pasar saham. Penelitian ini menggunakan kapitalisasi pasar saham untuk seberapa besar pasar saham di Indonesia. Hasil menunjukkan bahwa perkembangan pasar saham Indonesia pada jangka pendek dipengaruhi oleh lag perkembangan pasar saham, M2, credit to private sector, suku bunga riil, tabungan domestik bruto, FDI, keterbukaan perdagangan, dan krisis. Sedangkan pada jangka panjang dipengaruhi oleh M2, suku bunga ril, inflasi, FDI, dan keterbukaan perdagangan.

Judul: Impact of stock market development on Indonesian macroeconomic variables
Abstrak: Stabilitas sistem keuangan dapat mendorong beroperasinya pasar sehingga dapat meningkatkan perekonomian suatu negara. Pasar modal merupakan salah satu elemen penting dalam menjaga stabilitas sistem keuangan. Integrasi antara perkembangan pasar modal dan kondisi perekonomian menyebabkan banyak perhatian, sehingga banyak penelitian dilakukan terhadap integrasi tersebut. Penelitian ini mengevaluasi hubungan antara Indeks Harga Saham Gabungan (IHSG) dan indikator makroekonomi Indonesia. Hasil yang didapatkan dari penelitian ini adalah IHSG memiliki pengaruh yang cukup kuat terhadap peubah makroekonomi Indonesia. Ketika IHSG mengalami guncangan, beberapa peubah makroekonomi akan mengalami guncangan. Guncangan yang diberikan IHSG terhadap peubah makroekonomi hanya pada 4 periode awal sedangkan pada periode berikutnya peubah makroekonomi cenderung stabil. Berdasarkan hasil uji hubungan kausalitas, disimpulkan bahwa peubah yang memiliki hubungan 2 arah adalah peubah IHSG dan peubah IHK, peubah Indeks Harga Konsumen dan Industrial Production Index (IPI), serta jumlah uang beredar luas (M2) dan Indeks Harga Saham Gabungan., Stability of the financial system could incourage market operation so as to bush the economy of a country. The capital market is one of the important elements in maintaining financial stability. The integration between the development of the capital market and economic conditions caused a lot of attention, so a lot of research done on the integration. This study evaluated the relationship between Jakarta Composite Index (JCI) and the Indonesian macroeconomic indicators. The results obtained from this study is JCI has a strong influence on Indonesian macroeconomic variables. When JCI shocks, some macroeconomic variables will experience shock. JCI shocks given to the macroeconomic variables only at the beginning of period 4, while in the next period of macroeconomic variables tend to be stable. Based on the causality test results, it was concluded that the variables that have a two-way relationship is JCI with Consumer Price Index (CPI), Consumer Price Index (CPI) with Industrial Production Index (IPI), and broad money supply (M2) with JCI.

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.
