The Influence of Iteration Calculation Manipulation On Social Network Analysis Toward Twitter's Users Against Hoax In Indonesia With Single Cluster Multi-Node Method Using Apache Hadoop Hortonworkstm Distribution

摘要

Social network analysis (SNA) examines the relationship of nodes in the graph. This study uses Hadoop technology with the use of clustering method (High-Performance Cluster) and 5 SNA parameters (Degree Centrality, Betweenness Centrality, Closeness Centrality, Eigenvector Centrality, and PageRank) on hoax topic, by manipulating the iteration of calculation on Gephi tools. Based on 1 month of observations, the authors found 18 days where keyword hoax became the trending topic on Twitter. This means 58% of Twitter's users are more often talk about hoaxes. Intact-group comparison experiments are applied to Twitter data that will be grouped into 2 groups (controls and experiments). The authors were able to get data as much as 16,400 data during data gathering phase. Variable changes were performed in the experiment group. The addition of iteration from 100 to 200, which increase the value of degree centrality from 3601 to 5070 or about 40.79%. This research can be developed using True Experiment Design and the addition of Sentiment Analysis.
