Abstract
This study aims to develop geometry learning media on curved-solid objects using Ispring Suite 8 with 3D effects supported by Google SketchUp. It also aims to find the effectiveness of the media towards the basic geometry skills and the learning result of 9th-grade students of junior high school. This study is a development study which refers to Budiyono’s development model that includes four stages. These stages are the preliminary, product development, product trial on its effectiveness, dissemination and product implementation. The entire stage was imposed on three different schools in Karanganyar, one of a district in Indonesia, by using stratified cluster random sampling. Within the three schools, we took seven classes to join the effectiveness test through the assessment questionnaire and the before-after test, as well as the efficacy test after the expert's judgement using the validation sheet. The result shows that the geometry learning media is valid based on the experts' validation judgement, and also practical based on the teacher and students’ judgement in the trial of the product. The students’ basic geometry skills and learning result are improved after getting the treatment with the media. Finally, we can conclude that this media is effective and able to be used further in the junior high school level.

There were suggestions and feedbacks from the validators. They suggested fixing the system in the Ispring Suite 8 media to link with Google SketchUp
Summary
We found that the teachers’ activity only supported by text-book. They delivered the lesson without any visual model. To get a wider range of material, the students demanded a learning source that was from the textbook, for instance, from the internet; (2) The students still struggled to visualize the geometry shapes We conducted a literature study to find the syllabus information for the material referred to the basic competence It was to find the surface geometry area and curved-solid objects (cylinder, cone, and sphere) volume formulas as well as to solve the related contextual problem. Product Development The development stage started with composing the media draft It included the homepage, the sub-materials page of curved-solid objects, and the quiz page that made by Ispring quiz maker.
