Judul: The Impact of Macroeconomics Condition on Banking Performance in Indonesia
Abstrak: Beberapa penelitian menganalisis pengaruh kondisi makroekonomi terhadap kinerja perbankan, namun masih menghasilkan kesimpulan yang inkonsisten. Untuk itu, penelitian ini kembali menganalisis pengaruh kondisi makroekonomi terhadap kinerja perbankan berdasarkan lima indikator rasio kinerja keuangan, yaitu rasio profitabilitas, permodalan, efisiensi, risiko kredit, dan likuiditas di Indonesia dengan menggunakan pemodelan Autoregressive Distributes Lag (ARDL). Hasil estimasi menunjukan variabel-variabel makroekonomi memiliki hubungan atau keseimbangan jangka panjang dengan kelima indikator rasio kinerja perbankan. Dalam jangka panjang, rasio profitabilitas (ROA) dipengaruhi oleh nilai tukar. Rasio permodalan (CAR) dipengaruhi oleh IPI, inflasi, IHSG, dan harga minyak dunia. Rasio efisiensi (BOPO) dipengaruhi oleh IPI dan inflasi. Rasio risiko kredit (NPL) dipengaruhi oleh inflasi, nilai tukar, dan IHSG. Serta rasio likuiditas (LDR) dipengaruhi oleh nilai tukar, IHSG, dan harga minyak dunia. Pengaruh jangka pendek, rasio profitabilitas (ROA) dipengaruhi oleh IPI dan inflasi. Rasio permodalan (CAR) dipengaruhi oleh IPI, inflasi, dan IHSG. Rasio risiko kredit (NPL) dipengaruhi oleh IPI, inflasi, dan harga minyak dunia. Serta rasio likuiditas (LDR) dipengaruhi oleh inflasi, nilai tukar, dan IHSG., Several studied analyzed the impact of macroeconomics conditions on banking performance, but still yielded inconsistent conclusions. Therefore, this studied again analyzes macroeconomic conditions impact on banking performance based on five indicators of financial performance ratios, namely profitability, capital, efficiency, credit risk, and liquidity ratio in Indonesia used Autoregressive Distributes Lag (ARDL) modeling. The estimation results showed that macroeconomic variables had a long-term balance or relationship with the five banking performance ratio indicators. In the long run, profitability ratio (ROA) was affected by exchange rate. The capital ratio (CAR) was affected by IPI, inflation, IHSG, and oil price. The efficiency ratio (BOPO) was affected by IPI and inflation. The credit risk ratio (NPL) was affected by inflation, exchange rate, and IHSG. And the liquidity ratio (LDR) was affected by exchange rate, IHSG, and oil price. Short term effects, profitability ratio (ROA) was affected by IPI and inflation. The capital ratio (CAR) was affected by IPI, inflation, and IHSG. The credit risk ratio was affected by IPI, inflation, and oil price. And the liquidity ratio (LDR) was affected by inflation, exchange rate, and IHSG.

Judul: Profitability Analysis of Conventional Banks and Islamic Banks in Indonesia Before and During the Covid-19 Pandemic
Abstrak: Covid-19 memiliki dampak yang sangat besar dalam bidang ekonomi termasuk sektor perbankan. Penelitian ini bertujuan untuk menganalisis perkembangan rasio keuangan dan determinan yang memengaruhi profitabilitas bank konvensional dan bank syariah di Indonesia periode triwulan I-2019 hingga triwulan IV-2020. Sampel yang digunakan terdiri dari 10 bank konvensional dan 10 bank syariah. Penelitian ini menggunakan metode data panel dengan ROA sebagai variabel dependen. Adapun variabel independen terdiri dari CAR, NPL/NPF, NIM/NOM, BOPO, LDR/FDR, pertumbuhan ekonomi, dan inflasi. Hasil analisis data menunjukkan bahwa CAR dan NIM berpengaruh positif dan signifikan, serta BOPO berpengaruh negatif dan signifikan terhadap ROA pada bank konvensional. Pada bank syariah, hanya NOM yang menunjukkan pengaruh signifikan terhadap ROA dengan arah positif., Covid-19 has a huge impact in the economic field including the banking sector. This research aims to analyze the development of financial ratios and determinants that affect the profitability of conventional banks and Islamic banks in Indonesia in the first quarter of 2019 to the fourth quarter of 2020. The sample used consisted of 10 conventional banks and 10 Islamic banks. The study used the panel data method with ROA as a dependent variable. The variables independents consist of CAR, NPL/ NPF, NIM / NOM, BOPO, LDR / FDR, economic growth, and inflation. The results of the data analysis showed that CAR and NIM had a positive and significant effect, and BOPO had a negative and significant effect on ROA on conventional banks. In Islamic banks, only NOM shows a significant influence on ROA in a positive direction.

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.
