Thesis, Surakarta: Faculty of Teacher Training and Education, Sebelas Maret University Surakarta, July 25, 2023.

This study aims to determine; 1) the effect of integrating blended discovery learning with a bioenial website to empower KPS of grade X students on the material of environmental change and preservation and 2) the effect of integrating blended discovery learning with a bioenial website to empower the scientific attitude of grade X students on the material of environmental change. This research is a quasi-experiment method with a quantitative approach. The research design used was a posttest-only control group design to measure KPS and a pretest-posttest non-equivalent control group design to measure scientific attitudes. The population in this study were students in grades X1-X7 of SMA Negeri 3 Sukoharjo in the 2022/2023 academic year as many as 251 students. The sampling technique used was cluster random sampling. The samples of this study were X2 class as E1 class using the Blended Discovery Learning model with the Bioenial Website with as many as 36 students, X4 as E2 class using the Discovery Learning model without the Bioenial Website with as many as 36 students, and X5 as K class using the Problem-Based Learning model without the Bioenial Website as many as 36 students. Data collection questionnaire (scientific attitude), observation (KPS, scientific attitude, syntax implementation), and documentation. Data analysis techniques used ANOVA hypothesis testing for KPS and ANCOVA for scientific attitudes. The ANOVA test results showed the effect of integrating blended discovery learning with the bioenial website to empower KPS. The results of further testing with LSD show that Blended Discovery Learning is a treatment that is significantly different among the three class groups. The ANCOVA test results show that there is no difference in integrating blended discovery learning with the bioenial website to empower scientific attitudes.
