Abstract

Data of alumni from 2012 to 2015 found that the average percentage of students graduating on time was 22%. The comparison between the number of students who graduate on time and new students who enter each year is not comparable, therefore a study is needed to find out the factors that affect student graduation and to prediction of the graduation period of the student through data mining research using the C4.5 algorithm. The data tested was student alumni data from 2012 to 2015. The instruments studied include study period, academic year, GPA, corner focus, gender, intensity of work during college, type of thesis, intensity of campus internal organization, intensity of external organization of campus, UKT group, scholarship status, pre-college education, hobby intensity, intensity of game play, academic competition participation status, non-academic competition participation status, and availability of facilities and infrastructure. The best test results using percentage-split 75% obtained 83.33% accuracy as well as the rules contained in the decision tree.

Abstract

Creativity is important in facing a challenging future life. Therefore, current learning is focused on not only values but also soft skills such as student creativity. Few teachers provide opportunities for students to develop their creativity in the classroom. This creativity can be developed and trained through various learning strategies. Probem-based learning was chosen in this study as a means to increase students' creativity through two learning methods, experiment and demonstration.  This study seeks to determine the effect of experimental and demonstration methods with problem-based learning model on student creativity on Newton's law material.  The subjects included 72 tenth-grade science students in Surakarta, Central Java.  They were selected using the purposed random sampling technique where out of 8 tenth-grade science students in SMA Al Islam, Surakarta, 2 classes that met the research category were selected.  This experimental study collected the data using pretest and posttest for cognitive data and questionnaire using a Likert scale for student creativity data. Data were analyzed descriptively through independent sample t-test. The results showed that both methods through problem-based learning model had a significant effect on the level of student creativity. From the characteristics of the methods and the number of students in the high creativity category, experimental method is superior to be applied. It is implied that teachers can use the experimental method with problem-based learning model in Newton's law to develop student creativity soft skills.
