Abstract

Clustering is a one of the text operations to categorize documents using similarity contents to find the relationship between the news or topics. In this study, single-linkage clustering is used to categorize the content of tweets and generate a topic to each cluster. We used Manhattan Distance to calculated the distance between words. In this paper, we also used thesaurus for clusttering process. The data will be joined according to the tweets and distance of the closest synonym. The experiments were performed using 4 sets of data with different threshold values. The accurary of this system is evaluated using the value of purity. It will be used to compare the result between the system result and the references. It turn out, purity using a thesaurus is better than without using thesaurus, because the cluster will be joined when words have synonyms in tweets. The best clustering accurary obtained from first dataset with 0.0003 threshold value is 80.16%. Key words: Clustering, Hierarchical Clustering, Manhattan Distance, Single-Linkage Clustering, Thesaurus, Tweets

Abstract

Kemejing Village is geographically hilly with winding roads and minimal lighting, reducing visibility and potentially compromising the safety and security of road users, especially at night. This community service activity aims to improve visibility and safety for road users in Kemejing Village, Loano District, Purworejo Regency, by installing road reflectors and street lighting (PJU) using photocell sensors. The method used was community empowerment based on field actions, which included observation, planning, implementation, and evaluation, involving students, village officials, and the community. The results of this activity showed that the road reflectors and PJU using photocell sensors successfully improved visibility at night, provided automatic and energy-efficient lighting, and made road users feel safer and more comfortable. This activity provided positive benefits to the community and helped build village infrastructure that can continue to develop in line with the Sustainable Development Goals (SDGs).
