This study aims to develop a multiple choice evaluation tool based on Wondershare Quiz Creator in economic mathematics courses, so as to produce valid evaluation tools that can be applied to students in understanding learning. This type of research is development research with the ADDIE development method which consists of 5 stages namely Analysis (Analysis), Design (Design), Development (Evaluation), Implementation (Implementation), Evaluation (Evaluation). Before the trial, the Wondershare Quiz Creator-based evaluation tool was first conducted a validation test by media experts and material experts. In addition, a questionnaire for students' responses to the Wondershare Quiz Creator-based assessment tool was also conducted. The results of the media expert validation were good, the results of the validated material expert validation were very good and the results of the questionnaire responses of the students were very good, namely for media experts 89.58%, for material experts 89.58% and student responses questionnaire 90.67%. So the evaluation tool is feasible to use. From the results of the calculation of the final analysis of the average student test using the right-t test shows that the value of t_count is greater than t_ (table) which is 15.12> 1.70 then H_0 is rejected. In addition, the completeness test was carried out stating that the experimental class was completed in a classical manner with a percentage of 94%. This means that the multiple choice evaluation tool based on Wondershare Quiz Creator in mathematics courses at STEKOM Semarang is better. The conclusion in this study is the Wondershare Quiz Creator based multiple choice evaluation tool in valid economic mathematics courses according to media experts, material experts, and student responses, as well as classically completing that the experimental class is better than the control class.

This study aims to develop The Zero-based Ubuntu Open Source Distribution Operating System to minimize software piracy among students. Distribution Zero Development is implemented on Ubuntu 18.04 Linux with pinguy builder software, all functional requirements have been successfully implemented in accordance with the design. The planning used in this study is the development and use of the waterfall development model with stages, namely analysis, design, program making, program testing, implementation, to the stage of validity testing, practicality and effectiveness. The test was carried out using a validity questionnaire, practicality and user satisfaction questionnaire. The conclusion of the Zero Linux Ubuntu Open Source Distribution Operating System design is to make the Operating System easy to use by students so as to minimize software piracy among students.
