Judul: The Effect of Chicken Meat Prices, Covid-19, and  Other Determinants on the Spillover Effect of Inflation at the Regional Level in Indonesia
Abstrak: Pandemi Covid-19 berdampak pada pergerakan permintaan dan penawaran komoditas pangan strategis, salah satunya adalah daging ayam ras yang memiliki fluktuasi harga dan memberikan andil terhadap inflasi sebagai salah satu tolak ukur kondisi perekonomian. Pergerakan inflasi perlu diawasi serta dikendalikan dengan mempertimbangkan faktor moneter dan non moneter. Penelitian ini menganalisis perkembangan inflasi, harga daging ayam ras, upah minimum provinsi, suku bunga kredit konsumsi, dan kredit UMKM tingkat regional di Indonesia. Selain itu, penelitian ini menganalisis pengaruh determinan inflasi regional serta interaksi spasial yang berdampak pada spillover inflasi regional dengan mempertimbangkan dummy Covid-19. Penelitian ini menggunakan data bulanan dari 34 provinsi di Indonesia selama 2018-2021 dan dianalisis menggunakan metode panel spasial. Hasil penelitian menunjukkan harga daging ayam ras dan upah minimum provinsi memiliki pengaruh positif signifikan terhadap inflasi suatu provinsi serta provinsi terdekat. Sebaliknya, suku bunga kredit konsumsi, kredit UMKM, dan dummy Covid-19 memiliki pengaruh negatif signifikan terhadap inflasi suatu provinsi dan provinsi terdekat., The Covid-19 pandemic impacted the demand and supply of a strategic food commodity, such as chicken meat with fluctuating prices, thus affecting the inflation rate, which is one of the benchmarks for economic conditions. Inflation needs to be monitored and controlled by considering monetary and non-monetary factors. This study analyzes the development of inflation, chicken meat prices, provincial minimum wages, interest rates for consumption loans, and MSME loans. This study also analyzes the impact of regional inflation determinants and spatial interactions that impact the spillover of regional inflation bu considering the Covid-19 dummy. This study uses monthly data from 34 provinces in Indonesia for 2018-2021 and analyzes using the spatial panel method. The results showed that the price of chicken meat prices and the provincial minimum wage have a significant positive effect on inflation in a province and the nearest province. In contrast, interest rates for consumption loans, MSME loans, and the Covid-19 dummy have a significant negative effect on in a province and the nearest province.

Judul: The Effect of Rice Prices and Other Determinants on the Spillover Effect of Inflation Between Provincial Capitals in Indonesia
Abstrak: Pandemi Covid-19 berdampak pada perubahan keseimbangan permintaan dan penawaran agregat pada komoditas pangan strategis sehingga menyebabkan fluktuasi harga sehingga mempengaruhi tingkat inflasi yang merupakan indakator kestabilan perekonomian negara. Penelitian ini bertujuan untuk melihat pengaruh interaksi spasial harga beras dan determinan lain seperti upah minimum provinsi, suku bunga kredit, kredit UMKM dan pandemi Covid-19 terhadap inflasi di 34 ibu kota provinsi di Indonesia. Selain itu, penelitian ini juga menganalisis keterkaitan spillover effect inflasi antar 34 ibu kota provinsi di Indonesia. Penelitian ini menggunakan analisis panel spasial dengan tahun penelitian yaitu 2018-2021. Hasil penelitian menunjukkan bahwa terdapat interaksi spasial yang positif dan keterkaitan spillover effect inflasi yang signifikan. Berdasarkan hasil estimasi harga beras (positif signifikan), upah minimum provinsi (negatif signifikan), suku bunga kredit (negatif signifikan), kredit UMKM (negatif signifikan) dan faktor eksternal pandemi Covid-19 (negatif signifikan), terhadap interaksi spasial dan keterkaitan spillover effect inflasi di 34 ibu kota provinsi di Indonesia., The Covid-19 pandemic has an impact on changes in the balance of aggregate demand and supply for strategic food commodities, causing price fluctuations that affect the inflation rate which is the stability of the country's economy. This study aims to see the effect of the spatial interaction of rice prices and other determinations such as the provincial minimum wage, loan interest rates, MSME loans and the Covid-19 pandemic on inflation in 34 provincial capital cities in Indonesia. In addition, this study also analyzes the correlation between the spillover effects of inflation among 34 provincial capital cities in Indonesia. This study uses spatial panel analysis with the research year 2018-2021. The results showed that there was a positive spatial interaction and a significant correlation between the spillover effect of inflation. Based on the estimated rice price (significantly positive), the provincial minimum wage (significantly negative), loan interest rates (significantly negative), MSME credit (significantly negative) and the external factors of the Covid-19 pandemic (significantly negative), on spatial interactions and spillover linkages of influence inflation in 34 provincial capital cities 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.
