Abstract

The development of social media, particularly Twitter, has become a primary means for the public to express opinions, criticisms, and complaints regarding train services, ranging from delays, facility comfort, to ticket policies. The large number of opinions appearing in short, non-standard characters, and containing slang and emoticons makes manual analysis ineffective, resulting in service providers not optimally utilizing valuable information from the public. This study aims to analyze public opinion sentiment on Twitter regarding train services to systematically and structuredly determine public perceptions. The methods used in this study are K-Means Clustering and Support Vector Machine (SVM). K-Means is used to group public opinion based on similarities in language patterns and sentiments to obtain initial labels, while SVM is used to classify opinions into positive and negative sentiments more accurately. The research data comes from the Twitter platform and is obtained through a crawling technique. The maximum limit of tweets retrieved is set at 2005 tweets. The results show that the K-Means method is able to assist the initial labeling process of sentiment data, while the SVM algorithm can classify public opinion with an accuracy level of 99.02%. The combination of clustering and classification methods has proven effective in processing large-scale, unstructured opinion data. Based on the research results, it can be concluded that the sentiment analysis approach using K-Means and Support Vector Machines can provide an objective picture of public perception of train service quality. The results of this analysis are expected to be used by service providers as evaluation material and a basis for decision-making to improve service quality to the public

Abstract

The rapid development of information technology in the era of the Industrial Revolution 4.0 has had a major impact on various aspects of life, including the world of education and the daily lives of the younger generation. One of the most prominent technologies today is Artificial Intelligence (AI). Understanding of AI is still very limited, especially among teenagers who come from economically disadvantaged backgrounds, including children in orphanages. Children at the AL-Hidayah Padang Orphanage often face limited access to information and cutting-edge technology, including knowledge about AI. As part of the role of the tri dharma of higher education, lecturers have a responsibility to participate in educating the nation's life through community service activities. Through the PKM program entitled "Introduction to Artificial Intelligence Technology at the Al Hidayah Padang Orphanage", lecturers and students want to make a real contribution by introducing the basic concepts of AI to foster children and the orphanage's guidance. This socialization is expected to spark curiosity, enthusiasm for learning technology, and open their insights to future opportunities in the digital and artificial intelligence fields. This activity aims not only to provide a theoretical understanding of AI, but also to provide practical and interactive experiences through simple demonstrations, AI-based educational games, and inspiring discussions. With a fun and easy-to-understand approach, this activity is expected to be the first step in building technological literacy among the foster children and their caregivers at the Al Hidayah Orphanage in Padang.
