Sentiment Analysis Regarding the Name of “Nusantara” in Indonesia’s New Capital City Using Convolutional Neural Network

The decision of the government of the Republic of Indonesia to move the national capital from the Special Region of Jakarta to East Kalimantan became a hot topic of conversation among the people. Various capital city names have sprung up, including “Nusantara.” By applying Natural Language Processing (NLP) technology, this study aims to analyze public sentiment toward naming the new capital city of the Republic of Indonesia as “Nusantara.” This research uses the Cross Industry Standard Process for Data Mining (CRIS-PDM) method for its development and the Convolutional Neural Network (CNN) algorithm for sentiment classification. The data used in this study amounted to 4,344 Indonesian language text data, which would then be used for the preprocessing stage, followed by the vectorization stage using FastText and classified using CNN. The results show that the CNN algorithm has a sentiment classification accuracy value of 90%. Based on the results of an in-depth analysis, the number of positive sentiments was greater, with a total of 1,566, compared to a negative sentiment which amounted to 1,459 and a neutral sentiment which amounted to 1,319. The results of this sentiment analysis show that most Indonesian people can accept the name “Nusantara” as the new capital of the Republic of Indonesia.
