Assessing the progress of lectures ensures the involvement of lectures in the exercise of science dissemination by research, education, and community service. That job affects the performance of lecturers at universities throughout the country. The performance of lecturers is evaluated regularly because of the vast number of evaluation attributes. Manual assessment can take time and cannot be carried out. In the evaluation of lecturer’s outcomes, a decision support model is needed to facilitate decision making. This study applies the preference ranking organization method for enrichment assessment (PROMETHEE) as a decision model in Multi-Criteria Decision Making (MCDM) and Geometric Analysis for Interactive Aid (GAIA) as a geometric analysis in determining lecturer performance. This analysis resulted in the maximal value of an alternative of 2 with Phi 0.2333, followed by 1 and 3 alternatives. These results suggest that alternative 2 is the best way to assess the performance of lecturers as the main indicator. Alternative 3 is the least recommendable alternative because of its lowest precision on the basis of visualization results.

UCD (User Centered Design) is a design philosophy of putting users at the center of a system development process. The difficulties experienced by the tourists who visited West Sumatra during traveling is in communicating which can be helped by using UCD method. The approach using UCD method has been supported by various techniques, methods, tools, procedures and processes that help to design more user-centered applications. In the UCD method the user is at the level of design sophistication of all interfaces used based on the guide application. In making the application, the tool used in designing tourist guide application design is using Unified Modeling Language (UML). Data excavation is done by interview and observation to the end user, and library study. Tour guide application built using eclipse with SQLite database storage media. The result of this design is expected to provide convenience to the tourists in making tourism visits to West Sumatra.
