Abstract

This research aims to design a teaching materials for increasing motivation and learning achievement of the students in Microcontroller course, Department of Electronics Engineering, Politama Surakarta. It also aims to identify effects of using Arduino Kit teaching materials in motivation and learning achievement. Data is taken from 2 groups of Assembly Language course, each has 32 students. Research instruments use questionnaire, pretest and post-test. The questionnaire uses 5-point Likert Scale. The pretest and post-test use objective test with 4 options. Data is collected and analyzed with SPSS v23. Homogeneity and normality test are used before testing hypothesizes. Hypothesizes are tested with nonparametric statistics Mann-Whitney U-Test. Research results show that the use of Arduino Kit instructional media has positive impact on both motivation and learning achievement. The average score of motivation of the treatment group (72,90) is higher than the average score of motivation of the control group (68,19). Results also show that the post-test average learning achievement of the treatment group (26,49) is higher than the average learning achievement of the control group 22,03.

Abstract

There are various kinds of database server application, including MySQL and SQL Server. Each has advantages and disadvantages. Politama server uses SQL Server as its database server application. Program used to access this server is created with desktop applications. Up to this time applications can run smoothly. However, if the server is used to serve as many data requests at the same time, servers are often slow to respond. One solution to overcome this problem is to use an alternative database server application such as MySQL. Before it is implemented, we try to examine the response speed between SQL Server and MySQL. Comparisons were made using two computers with identical specifications. SQL Server and MySQL installed on each computer. Then, an application is created to access both the database server application. The tested instructions are SELECT, INSERT and DELETE. The results showed that MySQL applications provide better performance on all SQL commands. Access time to MySQL 1.85 times faster in SELECT command and 18.25 times faster at INSERT command KRS table records. The difference of access time increase as the number of record increase.
