Abstract

More than 13 countries in the Americas have reported sporadic Zika virus infection that show very rapid geographic expansion. While in Indonesia, the euphoria is also increasingly prevalent virus discussed especially after the discovery of Jambi positive patients infected with the virus Zika on January 26, 2016 last.Viruses transmitted by mosquito bites to humans are the same mosquito transmits dengue fever, chikungunya and yellow fever with symptoms that have similar resemblance to the zika virus. Based on similarity of symptoms of infection with dengue virus, can be analyzed using sequence alignment to get identical percentage, local alignment calculation, genetic mutation and the spread of the zika virus to Indonesia. From the whole process, Smith Waterman algorithm can be used to align dengue virus type 1, type 2, type 3, and type 4 with zika virus (Jambi). Mutations between dengue virus and zika virus on average 28% of dissimilarity sequences in the same position between the sequence. Overall, the dengue virus type 1 mutation to the zika virus was 28.2723%, the dengue virus type 2 mutation to the zika virus was 28.1984%, the dengue virus type 3 mutation to the zika virus 27.9373% and the mutation of dengue virus type 4 to the zika virus of 28.7206%. By looking at all mutations, from the simulation results note that the mutations of both viruses include mutation type I. The phylogenetic tree showed the spread of the Zika virus to Indonesia, originally from South Africa, the islands of Chile, Caledonia, the Philippines, Yap Micronesia, Thailand, Cambodia, and finally reached Indonesia. Zika virus jambi suspected of dengue virus mutation because a few years earlier there was a dengue virus outbreaks in a long time in Jambi, it turns out the virus zika jambi is not from mutation dengue virus but the virus comes from the Asian region.

Abstract

The allocation of student dormitory rooms often faces potential conflicts if not managed properly, especially when students from the same study program are assigned to the same room. This study aims to optimize the room assignment of students in Dormitory F at Universitas Islam Darul ‘Ulum by applying graph theory, specifically graph coloring using the Welch-Powell algorithm. Each student is represented as a vertex, and edges connect students from the same study program, indicating they should not share a room. The Welch-Powell algorithm colors the graph by ordering vertices in descending order of degree and assigning colors so that no two adjacent vertices share the same color. The results show that 14 students from 8 different study programs were successfully grouped into 4 rooms, ensuring no students from the same program share a room. This method effectively reduces potential conflicts, fosters an inclusive and heterogeneous dormitory environment, and broadens inter-program student interactions. The approach provides a practical solution for dormitory management to arrange room assignments efficiently and harmoniously.
