Based on the preliminary analysis, one of the things needed in learning is a learning media that describes the material clearly, briefly, easily understood, and fulfills offline and online learning. This research aims to develop a digital comic learning media on the concept of the human excretory system. This study uses the R&D (Research and Development) method with the ADDIE model. The instruments in this study include a validation questionnaire, practicality test sheets, readability questionnaire, and student response questionnaire sheets to the developed digital comic learning media. The research data were analyzed quantitatively by calculating the percentage. The results showed that the digital comics learning media was valid and feasible to be used as learning media (combined average of 83%). The results of the student response test showed a very good response to the digital comic learning media with a percentage of 84%

Abstract. The Phylogenetic tree is a visual representation depicts a hypothesis about the evolutionary relationship among taxa. Evolutionary experts use this representation to evaluate the evidence for evolution. The phylogenetic tree is currently growing for many disciplines in biology. Consequently, learning about the phylogenetic tree has become an important part of biological education and an interesting area of biology education research. Skill to understanding and reasoning of the phylogenetic tree, (called tree thinking) is an important skill for biology students. However, research showed many students have difficulty in interpreting, constructing, and comparing among the phylogenetic tree, as well as experiencing a misconception in the understanding of the phylogenetic tree. Students are often not taught how to reason about evolutionary relationship depicted in the diagram. Students are also not provided with information about the underlying theory and process of phylogenetic. This study aims to investigate the initial ability of undergraduate students in understanding and reasoning of the phylogenetic tree. The research method is the descriptive method. Students are given multiple choice questions and an essay that representative by tree thinking elements. Each correct answer made percentages. Each student is also given questionnaires. The results showed that the undergraduate students' initial ability in understanding and reasoning phylogenetic tree is low. Many students are not able to answer questions about the phylogenetic tree. Only 19 % undergraduate student who answered correctly on indicator evaluate the evolutionary relationship among taxa, 25% undergraduate student who answered correctly on indicator applying concepts of the clade, 17% undergraduate student who answered correctly on indicator determines the character evolution, and only a few undergraduate student who can construct the phylogenetic tree.
