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: Impact of the Macroeconomic Variabels on the Jakarta Composite Index (JCI) Return on Indonesia.
Abstrak: Pasar modal mempunyai peranan penting sebagai indikator perkembangan ekonomi suatu negara. Baik buruknya pasar modal dapat dilihat melalui indeks harga saham pada bursa efek. Perkembangan pasar modal di Indonesia bisa dilihat melalui return IHSG. Penelitian ini bertujuan untuk menganalisis pengaruh variabel makroekonomi terhadap return IHSG. Analisis yang digunakan dalam penelitian ini adalah Vector Error Correction Model (VECM) dengan menggunakan data dari Oktober 2005 sampai Februari 2016. Hasil analisis menujukkan bahwa guncangan BI Rate, uang beredar (M2), Indeks Harga Konsumen (IHK) dan Indeks Produksi Industri (IP) direspons negatif oleh return IHSG. Sementara guncangan nilai tukar direspons positif oleh return IHSG. Guncangan nilai tukar memiliki kontribusi terbesar dalam menjelaskan variasi return IHSG. Sedangkan guncangan dan BI Rate, M2, IP dan IHK memiliki kontribusi yang relatif lebih kecil dalam menjelaskan variasi return IHSG.

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.
