Abstract

Application which is a computer program that made to do and implement a special assignment from users, in which the application can be used many people to ease in the daily. in STMIK Nurdin Hamzah contract lecture is still classified as manual, especially student who have to write the registration form study as many as three sheets of in accordance with the subjects that will taken, that calls for more of the time and energy. This is exactly the foundation for a review what do research on STMIK Nurdin Hamzah. In conducting the study, the authors using some of the research methodology, including field research, to the library and laboratory. This application was built with support for Visual Basic 2013, Crystal Report 13 as well as additional libraries are required. Furthermore, the application that has been built is expected to be more helpful STMIK Nurdin Hamzah in contracting lectures, such as the students taking the course. From the results of this study concluded contract applications lectures pas STMIK Nurdin Hamzah were made with the aim of helping STMIK Nurdin Hamzah in data processing of the contract relating to the students, and the application is built with support for Visual Basic 2013, Crystal Report 13 as well as additional libraries are required.

Abstract

Misconceptions in learning chemistry have the potential to have a negative impact because of the close interrelationship of chemical materials. This study aims to develop an effective five-level diagnostic test to identify students' misconceptions in the topic of chemical equilibrium. Through the R&D approach and Rasch model. Data from validation by experts (3 chemistry lecturers and 2 high school teachers) were processed using Minifac software. Furthermore, the raw data from the pilot test on 32 students were analyzed with Ministep software. The results of the analysis showed that the research instrument had good content validity, sufficient to very good reliability (0.70-0.86), the analysis of the difficulty index showed that the questions at the first and third levels had four categories of difficulty, while at the fifth level there were three categories. The differentiated power of the questions also showed a similar pattern, with four categories in the first and third levels and three categories in the fifth level.
