Judul: Factors Influencing the Success of Currency Redenomination: Historical and Experimental Approach
Abstrak: Redenomination is a simplification of nominal value of currency by reducing digit (zero number) without reducing the real value of the currency. Factors Influencing the Success of Currency Redenomination is a research about whether the economic conditions at the time of redenomination, such as inflation and economic growth, may affect the success of currency redenomination implementation. The success of redenomination can be seen from changes on the level of inflation and economic growth after the redenomination policy is applied. This research is useful for central bank and government to provide inputs in the preparation of the Rupiah Price Changes Draft Law, especially in terms of timeliness of redenomination policy implementation. This study has three objectives that include the following: (1) to examines the factors that affect the successful of currency redenomination implementation in a country; (2) to analyze the effect of redenomination policy on changes of selling prices, number and value of transactions in the market in a variety of different economic conditions; and (3) to assess public perceptions, as producers and consumers, toward Rupiah redenomination policy. This research was based on primary and secondary data. Primary data obtained through simulation experiments of buying and selling rice. The primary data used are responses of 48 experimental subject as economic actors in the experiments. In addition, primary data were also obtained through a survey of 168 respondents. Secondary data used are historical data economic indicators of 30 countries that have been redenominated their currencies from 1963 to 2008. Multiple regression model is used to examine the factors that affect the successful of currency redenomination implementation. Meanwhile, primary data generated through experimental design were analyzed using different test mean values of two independent populations. Afterward, descriptive analysis is used to describe the public perceptions of redenomination policy. Multiple regression model indicates that the successful of redenomination tends to be influenced by economic conditions when a country implements its currency redenomination. Countries that implement redenomination when inflation rate was low (<10%), then inflation rate one year thereafter will be lower than countries that implement redenomination when inflation rate was high (≥10%). Meanwhile, inflation will decrease and economic growth will rise higher after redenomination, if previously a country have experienced high economic growth as well. Based on experimental results of buying and selling rice, when inflation was high, redenomination policy could increase the selling price. Otherwise, when inflation was low, redenomination could decrease the selling price. Changes in selling price after redenomination was not affected significantly by differences in economic growth conditions. In different economic conditions, redenomination policy did not significantly affect the changes number of transactions and total value of transactions in the market. From the survey results, public did not believe government can control inflation after redenomination. Redenomination also will not affect consumption pattern and public is not too convinced redenomination can strengthen the Rupiah exchange rate. The important thing on currency redenomination is economic conditions at the time of policy implementation. It would be better if redenomination implemented when the economy is in good and stable condition, such as low inflation rate and

Judul: Pengaruh Redenominasi dan Faktor Lainnya terhadap Kinerja Perekonomian: Pendekatan Eksperimental dan Historis
Abstrak: Adanya wacana kebijakan redenominasi telah ada sejak 2010, namun pada tahun 2016 kembali mencuat dengan diajukannya Rancangan Undang-undang Perubahan Harga ke Proglenas. Redenominasi dilatar belakangi oleh adanya jumlah digit yang terlalu banyak menimbulkan ketidakefisienan. Selain itu, Rupiah masuk dalam garbage money yaitu masuk 10 besar nilai tukar terlemah di dunia. Oleh karena itu diperlukan kebijakan untuk meningkatkan kredibilitas mata uang rupiah di mata dunia. Disamping itu, kegagalan dan keberhasilan kebijakan redenominasi juga dipengaruhi oleh faktor-faktor lain pada saat negara tersebut menerapkan kebijakan redenominasi. Tujuan Penelitian ini adalah untuk mengkaji pengaruh pertumbuhan ekonomi, jenis barang, masa transisi dan tahapan redenominasi terhadap kinerja perekonomian yaitu harga transaksi dan jumlah transaksi yang dikaji dengan pendekatan eksperimental. Selain itu, juga menganalisis faktor-faktor yang memengaruhi kebijakan redenominasi dengan pendekatan historis. Penelitian ini menggunakan data primer dan data sekunder. Data primer dikumpulkan dengan menggunakan percobaan ekonomi, dimana responnya dilihat terhadap harga transaksi dan jumlah transaksi, sedangkan data sekunder merupakan data yang diambil dari 32 negara yang telah melakukan redenominasi (baik negara yang berhasil dan gagal dalam menerapkan redenominasi) dari tahun 1963- 2008. Data sekunder yang dikumpulkan adalah data inflasi, pertumbuhan ekonomi, suku bunga, tingkat pengangguran, pertumbuhan uang, dan tingkat demokrasi suatu negara pada saat menerapkan kebijakan redenominasi. Pengolahan data primer menggunakan uji beda nilai tengah, sedangkan data sekunder menggunakan model regresi logit dengan menggunakan software SPSS. Dilihat dari hasil penelitian, implikasi kebijakan redenominasi terhadap harga transaksi dengan menggunakan percobaan ekonomi bahwa kebijakan redenominasi baik di lakukan pada kondisi pertumbuhan ekonomi yang tinggi, tahapan redenominasi secara langsung dan dengan menggunakan masa transisi. Selain itu, sifat barang inelastis setelah adanya kebijakan redenominasi cenderung mengakibatkan harga transaksi meningkat dan penurunan jumlah transaksi sedangkan sebaliknya untuk barang elastis setelah redenominasi cenderung mengakibatkan penurunan harga transaksi dan peningkatan jumlah transaksi. Kesuksesan suatu negara juga disebabkan oleh negara yang menerapkan kebijakan redenominasi pada saat pertumbuhan ekonomi tinggi tingkat pengangguran yang rendah, serta tingkat demokratisasi yang tinggi memiliki peluang keberhasilan yang semakin tinggi dalam menerapkan kebijakan redenominasi.

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.
