Judul: Inflasi dan Pertumbuhan Ekonomi: Pendugaan Ambang Batas Inflasi di Indonesia.
Abstrak: High inflation is regarded as a problems in the economy. Indonesia experienced economic collapse as a result of failing to control inflation volatility. This is used as a reason for the current authorities to implement low-inflation policy. The economist argues that low-inflation can promote economic growth faster. In fact, low-inflation policy is not favorable because it interferes the business investment climate. On the other hand the pattern of the inflation and economic growth data in Indonesia is also inconsistent (indicating a positive relationship, negative and neutral). The purpose of this study is to determine the effect of inflation on economic growth, as well as to search inflation threshold in Indonesia in the period 1970- 2012. Using multiple linear regression, this study shows that inflation negatively impacts on economic growth. Inflation threshold identification by Khan and Senhadji model (2001) stated that inflation threshold in Indonesia is 7.11%. While according to Hansen model (1997, 2000), inflation threshold in Indonesia is 9.53%. Based on some model selection criterias, the inflation threshold implied by Hansen model is more apropriate. Inflation has a positive effect on economic growth if the value is less than the thresholds and negative when it exceeds the thresholds. This result supports Chowdhury and Ham (2009) finding who stated that inflation threshold in Indonesia is between 8.5 per cent and 11 per cent. The two studies imply that the central bank should only pursue active policy measures when inflation is above the threshold. Thus, ITF cannot be generalized to all levels of inflation.

Judul: Efek Threshold dalam Hubungan antara Inflasi dan Pertumbuhan Ekonomi Regional di Indonesia
Abstrak: Penelitian terbaru menyatakan bahwa hubungan antara inflasi dan pertumbuhan ekonomi tidaklah linier. Saat inflasi melebihi threshold tertentu, akan berpengaruh negatif terhadap pertumbuhan ekonomi. Penelitian ini bertujuan untuk mengetahui hubungan linier dan tidak linier antara inflasi dan variabel kontrol lain dengan pertumbuhan ekonomi di Indonesia menggunakan data panel provinsi. Hubungan linier diuji menggunakan panel fixed effect sedangkan hubungan tidak linier diuji menggunakan panel threshold fixed effect. Secara linier, inflasi berpengaruh negatif terhadap pertumbuhan ekonomi, begitu juga dengan pertumbuhan rasio pengeluaran pemerintah dan pertumbuhan penduduk. Sementara pertumbuhan investasi dan pertumbuhan keterbukaan ekonomi berpengaruh positif terhadap pertumbuhan ekonomi. Saat melakukan uji tidak linier, threshold inflasi yang ditemukan ada dua titik yaitu 5.09 persen dan 9.57 persen. Inflasi di Indonesia berpengaruh negatif terhadap pertumbuhan ekonomi saat nilainya melebihi 9.57 persen. Stakeholder yang bertanggungjawab dalam kebijakan pengendalian inflasi di Indonesia seperti Bank Indonesia (BI) dan Pemerintah Daerah yang tergabung dalam Tim Pemantauan dan Pengendalian Inflasi Daerah (TPID) harus terus berkoordinasi dalam upaya mengendalikan gejolak harga, terutama harga pada level regional baik provinsi, kabupaten maupun kota di Indonesia. Hal ini dilakukan karena inflasi yang tinggi dan bergejolak tidaklah bagus bagi perekonomian. Bank Indonesia sebaiknya membuat target inflasi jangka panjang dengan batas atas sebesar threshold inflasi 5.09 persen. Sementara itu batas atas target inflasi jangka pendek sebesar threshold inflasi 9.57 persen. Kata kunci: inflasi, pertumbuhan ekonomi, threshold

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.
