The purpose of this study was to determine the science process skills of high school students through scientific approach-based learning on the topic of Biology, Monera and Circulation Systems. This study involved students in grades X and XI from two public high schools in Palembang City. This research uses Quasi Experimental method with Non-equivalent Control Group Design research design. Collecting data using a written test of 25 questions consisting of 5 aspects of science process skills (observing, communicating, classifying, interpreting data, and planning experiments). Data were analyzed by Mann-Whitney test. The results showed that there was a significant increase in science process skills on both learning topics with a significance value of p=0.000 and 0.001, respectively. The improvement of science process skills in students is included in the medium category, with an average normalized gain (n-gain)=0.55 and 0.44. The highest increase in science process skills was in the classification aspect (n-gain=0.95) and the lowest was in the communication aspect (n-gain=0.36). Based on the results of this study, it is shown that learning based on a scientific approach can improve the science process skills of high school students in learning biology on the topic of Monera and the circulatory system.
