Abstract

Sensitivity analysis is an important method in linear programming used to evaluate the impact of parameter changes on optimal solutions in production optimization. This study aims to identify and analyze various sensitivity analysis methods applied in previous studies. Through a systematic literature review approach, the research finds that sensitivity analysis provides valuable insights into solution stability and the effects of parameter changes on optimal outcomes. The findings indicate that this method can support better strategic decision-making in industrial contexts. The results of this research are expected to offer practical recommendations for practitioners to enhance production efficiency and effectiveness.

Abstract

The purpose of this study is to examine how the art festival organized by students participating in the Community Service Program (KKN) of the State Islamic University of North Sumatra in Nagori Bukit Rejo serves to enhance social interaction, promote diversity, and encourage the development of the village community.  This research was conducted using qualitative methods with a Participatory Action Research (PAR) approach, which involved observation, interviews, and documentation during the Art Festival activities. The results of the study show that the art festival not only serves as a place of entertainment, but also as a social and educational tool that can help strengthen solidarity among residents across age, ethnicity, and religion. Overall, the art festival helps preserve local culture, foster a sense of community, and raise awareness of the importance of diversity in social life.
