Scholars have analysed moral values in textbooks and children's storybooks, but little research has examined how these values are portrayed in storybooks written by young Indonesian authors. This research examines how young Indonesian authors incorporate moral values into their narratives to bridge this gap. The study is focused on the Kecil-Kecil Punya Karya (KKPK) series, which is commonly written by children across Indonesia. Using Moral Foundations Theory (MFT) and a mixed-methods approach, the study aims to understand the moral perspectives expressed in these texts written by young people. The findings indicate that young authors intentionally choose vocabulary, expressions, and narrative events to introduce and reinforce moral principles. Their stories highlight prosocial values such as helping others, showing respect and politeness, and demonstrating empathy and care toward peers, family members, and the wider community. These values align closely with ethical principles embedded in Indonesia’s national ideology, Pancasila, particularly those emphasising cooperation, social harmony, and respect for others. Children's storybooks are not only entertaining but also educational tools that subtly instill and transmit societal moral values. The study emphasises the importance of young authors in shaping moral awareness and supporting cultural development among young readers.
