The lack of use of learning media at SD Negeri Kutowinangun 08 Salatiga causes the learning outcomes of water cycle material in class V to be low. Based on these problems, this study aims to develop and test the feasibility, as well as the effectiveness of diorama media on water cycle material, hereinafter referred to as PBL-based SIAR in grade V. This R&D research adapts 9 of the 10 steps of the Borg and Gall development model. Quantitative and qualitative data obtained were collected using test and non-test techniques using questionnaire instruments, observation, interviews and documentation which were then analyzed descriptively and inferentially. The developed media was validated by media experts and material experts who showed very valid criteria with a percentage of 82% and 90.67%. Based on the results of the paired sample t-test test, it is known that the significance value is 0.000 <0.05 so that H0 is rejected and Ha is accepted, which means that the product developed is effective in improving student learning outcomes. The N-Gain test results obtained a gain value of 0.64 (medium). Based on the results of the response questionnaire distributed very positive from teachers and students. From these results it can be concluded that the diorama media SIAR (water cycle) based on PBL developed is very feasible and effective to improve the learning outcomes of IPAS fifth grade students of Kutowinangun 08 Salatiga State Elementary School.
