Indonesia's large land area makes it home to a wide variety of animals. For personal gain, many animals are hunted and even killed. Body parts of animals are used as accessories, consumed until they are collected, leaving scarcity in their wake. The research aims to make an illustrated children's book that educates children about saving and caring for endangered species. Children's book illustrations combine text and illustrations to tell stories. A descriptive qualitative approach is used in this study. The data obtained were in the form of observations, literature studies, responses of children aged 8-10 years in Surakarta City and interviews with endangered species experts at the GembiraLoka Zoo. The contents of the story raise the topic of threats to endangered species, their rescue and maintenance. The design of the book begins with conducting research, making predictions about the budget for making the book, creating a storyline, sketches and layout for the book "Exploring Time at the Zoo". With children's book illustrations, it is hoped that children will care more about the environment and love animals
