Judul: Aplikasi Theory of Planned Behavior dan Atribut Produk terhadap Keputusan Pembelian Susu Cair dalam Kemasan pada Mahasiswa Indonesia dan Malaysia
Abstrak: Tingkat konsumsi susu di Indonesia masih lebih rendah dibandingkan negara lain di ASEAN, termasuk Malaysia. Perbedaan letak geografis membuat konsumen memiliki perbedaan perilaku dalam keputusan pembelian produk. Berdasarkan theory of planned behavior (TPB), keputusan pembelian dibentuk niat yang dipengaruhi oleh sikap, norma subjektif dan pengendalian perilaku. Atribut produk dianggap memengaruhi keputusan pembelian, seperti harga, citra merek, kemasan dan kualitas. Penelitian ini bertujuan membandingkan pengaruh theory of planned behavior dan atribut produk terhadap keputusan pembelian susu cair dalam kemasan pada mahasiswa Indonesia dan Malaysia. Penelitian ini menggunakan survei online pada 200 mahasiswa Indonesia dan Malaysia dengan metode convenience sampling dan analisis SEM PLS. Hasil penelitian menunjukkan bahwa ada perbedaan variabel TPB yang signifikan, pada mahasiswa Indonesia adalah sikap dan pengendalian perilaku, sedangkan pada mahasiswa Malaysia, yaitu sikap, norma subjektif dan pengendalian perilaku. Variabel atribut produk yang signifikan pada mahasiswa Indonesia adalah kemasan dan citra merek, sedangkan pada mahasiwa Malaysia tidak ada variabel atribut produk yang signifikan.

This research is intended to as follows : (1) to identify the characteristic of the costumers of Ultra Milk, (2) to identify a process of deciding to buy Ultra Milk, (3) to analyze the factors influencing the customers’ decision to buy Ultra Milk, (4) to analyze customers attitude towards the attributes owned by Ultra Milk. The data used in this research are primary and secondary. The primary data are taken from the spreading of questionaires and the secondary data are taken from a library study, information on the internet, and a study of references. Secondary data are taken frombook’s study, internet and literature’s study.The technique to take samples used in this research is a quota sampling. The means of analyzing are the descriptive analysis, the factor analysis and a model of MultiattributeFishbein analysis with the help of SPSS software version 17 and Microsoft Excel. The results of the research show that the majority of the customers of Ultra Milk’s liquid milk are the female university students (62%), aged 21 years old (46%), their origins of Jakarta, Bogor, Tangerang and Bekasi (41%).

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.
