These findings contribute to the management of vocational education as an effort to implement VHS revitalization. However, it is also possible that these findings can apply more broadly to student learning in other skills competencies in VHS. This finding is very useful for vocational teachers as an effort to improve the learning process of building interior design. On the other side, the students who have a low need for motivation, the use of the Google SketchUp application does not differ significantly compared to the use of PowerPoint Slides. For students who have a high need for motivation, using the Google SketchUp application is more effective than using PowerPoint Slides.

There is an interaction between the Google SketchUp application and the students’ need for achievement. Students who classified with a high need for achievement earn higher learning achievement compared to the lower one. The results show that the Google SketchUp application is more effective than the PowerPoint in the learning of building interior design. To test the hypothesis using multiple variance analysis techniques and the Tukey test. The instruments used are need for achievement tests and learning achievement tests with reliability coefficients of 0.916 and 0.671. The sample consisted of 56 VHS students, study program of modeling design and building information. The Google SketchUp application was used in the experimental group, while the PowerPoint Slides were used in the control group. Quasi-experimental research was conducted at the Vocational High School (VHS) with a 2 x 2 factorial design. This study aims to find out the effect of the Google SketchUp application and the need for achievement on students’ learning achievements of building interior design.
