Judul: The Influence of Internal and External Factors on the Proportion of Working Capital Financing at Islamic Commercial Bank in Indonesia
Abstrak: Sejak tahun 2014, proporsi pembiayaan modal kerja Bank Umum Syariah (BUS) cenderung menurun dan kondisi terburuk terjadi pada tahun 2020. Penelitian ini bertujuan untuk menganalisis faktor internal dan eksternal yang memengaruhi proporsi pembiayaan modal kerja oleh BUS di Indonesia dengan menggunakan data bulanan dari Juli 2018 hingga Oktober 2021 dan menggunakan metode Vector Error Correction Model (VECM). Hasil penelitian menemukan bahwa berdasarkan estimasi VECM, seluruh faktor internal dan eksternal berpengaruh signifikan terhadap proporsi pembiayaan modal kerja. Proporsi pembiayaan modal kerja merespon guncangan inflasi, PDB, dan SBIS secara positif, sedangkan guncangan DPK dan NPF direspon secara negatif. Inflasi memberikan kontribusi yang dominan dalam menjelaskan keragaman proporsi pembiayaan modal kerja pada BUS di Indonesia., Since 2014, the proportion of working capital financing for Islamic Commercial Banks (BUS) has tended to decline and the worst condition occurred in 2020. This study aims to analyze internal and external factors that affect the proportion of working capital financing by BUS in Indonesia by using monthly data from July 2018 to October 2021 and using the Vector Error Correction Model (VECM) method. The results of the study found that based on the VECM estimation, all internal and external factors had a significant effect on the proportion of working capital financing. The proportion of working capital financing responded positively to inflation, GDP, and SBIS shocks, while TPF and NPF shocks responded negatively. Inflation makes a dominant contribution in explaining the diversity of the proportions of working capital financing for BUS in Indonesia.

Judul: Analyzing Market Share Determinants of Islamic Commercial Banks and Islamic Business Units in Indonesia period 2012-2022
Abstrak: Perkembangan perbankan syariah di Indonesia saat ini masih tertinggal dari perbankan konvensional. Hal ini dapat dilihat dari market share perbankan syariah yang kecil dibandingkan dengan perbankan konvensional. Penelitian ini bertujuan untuk menganalisis determinan market share bank umum syariah (BUS) dan unit usaha syariah (UUS) di Indonesia periode 2012 – 2022. Variabel yang digunakan dalam penelitian ini adalah dana pihak ketiga (DPK), capital adequacy ratio (CAR), non performing financing (NPF), return on assets (ROA), financing to deposit ratio (FDR), Inflasi, dan BI rate. Penelitian ini menggunakan metode vector error correction model (VECM). Hasil penelitian menunjukkan bahwa dalam jangka panjang, FDR berpengaruh signifikan positif, DPK, CAR, inflasi, dan BI Rate berpengaruh signifikan negatif, NPF berpengaruh positif tidak signifikan, serta variabel ROA berpengaruh negatif tidak signifikan terhadap market share BUS dan UUS di Indonesia., The development of Islamic banking industry in Indonesia is still lagging behind the conventional banking industry. It can be seen from the market share of Islamic banking which is relatively small compared to market share of conventional banking. This study aims to analyse market share determinants of Islamic Commercial Bank and Islamic Business Unit in Indonesia period 2012 – 2022. Variables used in this study include the Third Party Fund (DPK), Capital Adequacy Ratio (CAR), Non Performing Financing (NPF), Return on Assets (ROA), Financing to Deposit Ratio (FDR), inflation, and BI Rate. This study uses Vector Error Correction Model (VECM). The results show that in the long term model, FDR has significant positive effect, DPK, CAR, Inflation, and BI Rate has significant negative effect, NPF has positive effect but not significant, while ROA has negative effect but not significant on market share of Islamic Commercial Banks and Islamic Business Units in Indonesia.

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.
