This article investigates Permadi Lyosta's works from an aesthetic point of view by applying qualitative research methods and descriptive analysis. The technique used is to document Permadi Lyosta's works in in-depth interviews with resource persons who are considered competent and credible. Next, analyse and evaluate the data, classify and reduce the data, and then write the research results. The results that can be put forward are that the ideology believed to be for the benefit of the public is not just a sign or standard of norms to be guided. But it seems that Permadi has been ingrained in his flesh, painting as if it was just a vehicle or a way to apply this ideology. Painting or being a painter is not the only goal but a bridge to achieve what he is being fought for. Therefore, Permadi's paintings do not tend to be in an abstract/imaginative style but depict the real life of the people he has travelled with. Because of that, understanding Permadi's aesthetics is not enough if seen from his paintings but also by tracing his life's bitter and sweet lives. Permadi offers an aesthetic that is not only socialist and revolutionary but also humanistic
