Judul: Indonesian Stock Market Reaction to the Dynamics of Global Economic Policy Uncertainty
Abstrak: Guncangan ketidakpastian dunia memberikan kontraksi mendalam bagi pemangku kebijakan dalam menciptakan iklim perekonomian kondusif, khususnya dalam sektor pendanaan dan investasi saham. Selain itu, kondisi makroekonomi juga turut memberikan kontribusi dalam volatilitas nilai saham di Indonesia, sehingga penelitian ini dapat difokuskan dalam mengkaji pengaruh jangka panjang dan pendek dari Indeks Global Economics Policy Uncertainty (GEPU) dan variabel makroekonomi Indonesia terhadap Indeks Harga Saham Gabungan (IHSG) pada periode bulan Januari 2000 hingga Desember 2023 dengan menggunakan metode ARDL-ECM. Hasil penelitian menunjukan bahwa dalam jangka pendek kenaikan dari GEPU, suku bunga Bank Indonesia, nilai tukar riil efektif, Indeks Harga Konsumen (IHK), dan harga minyak dunia berpengaruh signifikan terhadap IHSG. Pada jangka panjang, hanya GEPU, IHK, dan indeks harga minyak global yang berpengaruh signifikan terhadap IHSG., The shock of world uncertainty has provided a deep contraction for policy makers in creating a conducive economic climate, especially in the funding and stock investment sectors. Apart from that, macroeconomic conditions also contribute to the volatility of stock values in Indonesia, so this research can be focused on examining the long and short term influence of the Global Economics Policy Uncertainty Index (GEPU) and Indonesian macroeconomic variables on the Composite Stock Price Index (IHSG) in the period January 2000 to December 2023 using the ARDL-ECM method. The research results show that in the short term the increase in GEPU, Bank Indonesia interest rates, real effective exchange rate, Consumer Price Index (CPI), and world oil prices have a significant effect on the IHSG. In the long term, only GEPU, CPI and the global oil price index have a significant effect on the IHSG.

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.
