This research is quasi-experimental with a two-group pretest-posttest design. The research population is all grade 11th IPA SMAN 3 Bungo students, and the sample was determined by random sampling. Three projects conducted by the students were water pump free energy, fountain free energy, and air bubble generator. Two instruments of creative thinking test in essay form and multiple-choice for learning outcome test were used. The averages of pretest results of creative thinking and learning outcomes were 27.97 and 30.00 for the experiment class and 30.16 and 30.31 for the control, respectively. This shows that initial student ability in both the creative thinking skill and learning outcome of both types are level. STEM integrated PJBL was then used in the experiment class, and a conventional learning strategy was used for the control class. The average posttest results indicate that the student creative thinking skill of the STEM integrated PJBL class (82.81) is significantly higher than that of the control (36.72). Contrast with the posttest learning outcome showed no difference. These results show that the students actively engaged with the projects in the STEM integrated PJBL class improved their creative thinking skills significantly compared to the control class. This research's main finding is that implementing the STEM-integrated PJBL effectively enhances students' creative thinking skills. Manova analysis shows the students of the experiment class scored 76% in high and 63% in medium categories for both the creative thinking skills and learning outcome, respectively

A Study of Sound Materials of Water Hyacinth (Eichhornia Crassipes) as Alternative STEAM Integrated Project-Based Learning Model (PjBL)
No full textThis study aims to find an alternative sound-absorbing material from nature that is cheap and environmentally friendly, namely the water hyacinth plant (Eichhornia crassipes). The experimental soundproofing tool from a glass box with a placemat skat was developed by integrating science, technology, engineering, arts, and mathematics (STEAM) elements as an alternative project-based learning model (PjBL) for students. The research method used is experimental. Water hyacinth was sun-dried, woven in the form of a placemat with two variations of the test samples at several frequencies of 250 Hz, 500 Hz, 750 Hz, 1000 Hz, and 1500 Hz. Six stages of PjBL are used, and elements of STEAM are integrated. The results of the study obtained the value of Noise Reduction (NR) of sound for test samples 1, test sample 2, or a combination of test samples 1 and 2. Each test sample is effective at 1500 Hz high frequency; namely, test NR 1 = 8.7 dB, test NR 2 = 8.3 dB, and NR Gab=9.3 dB. The combined test sample was also effective at frequencies of 500 Hz and 750 Hz, with NR Gab=4.3 dB and NR Gab=4.7 dB. Following the theory that changes in sound between 3 to 12 dB have effects that humans can feel. This study concludes that natural water hyacinth fiber has fairly good quality as an alternative sound-dampening material. This experimental tool can also be an alternative to the STEAM-integrated PjBL learning model
