Abstract

During this time the determination of the best homeroom teacher at MIS Nurul Huda Pantai Labu  was still using a manual process , so the results were not optimal. In this study the  decision support system was built to facilitate the school in determining the best homeroom teacher using the Topsis method. The criteria used are 5: attendance, organizational experience, data on student achievement, interaction with students, and final education. This system design application is expected to help the school principal in making decisions about determining the best homeroom teacher

Abstract

In best selection process such as best student, best employee, best destination, etc. need an effective method so it may have the best object in output. Criteria on each process consist of among qualitative variable and numeric variable. In fact, to make a decision we cant use our feeling but should use science method. In our research we offer integrated AHP (Analytical Hierarchical Process) and Fuzzy-Promethee to solve the selection process that has among categorical variable. The result show algorithm from integrated AHP and Fuzzy-Promethee.

Abstract

This study aims to see the effect of realistic mathemathic education models on students' mathematical reasoning abilities in terms of learning styles. This type of research is quantitative. Data collection techniques used are essay tests and interviews. The data analysis technique used is hypothesis testing using anava 2 roads. However, before the anova test is carried out, the normality, homogeneity and balance test are carried out first. Based on the data that has been known that normal data, based on the same and balanced variance, the 2-way ANOVA test results show that there is an influence of the RTE model on students' mathematical reasoning ability, namely the reasoning ability of students with the RME model treatment is better than mathematical reasoning ability with conventional treatment methods. In addition, there is the influence of student learning styles on students' reasoning abilities.

Abstract

This study aims to obtain zeolite powder from Sarulla natural zeolite as an adsorbent, particle size of zeolite powder, and water analysis before and after water purification. The benefit is to increase the benefits of zeolite to a higher economic value.The method used is the grinding mill method to smooth the zeolite chunks. Whereas the water purification process uses a screening process.The results of this study were zeolite produced at 200 mesh or 74 microns, and the purification was successfully carried out.The conclusion of this study is that zeolite powder obtained from Sarulla natural zeolite as an adsorbent, obtained zeolite particles namely 200 mesh or 74 microns, and the water purification process was successfully carried out.

Abstract

This paper we propose graceful labeling and  labeling on a graph then referred to as 8-Bintang graph, the basic idea of formulation graceful labeling and  labeling on an alfabet bintang graphs wih the question a stars graph . Then we constructing graceful labeling and  labeling on the 8-Bintang graph with circle graph  for  odd.  The results obtained are illustrated in the theorem that the 8-Bintang graph with  for  odd has the following graceful labeling with the proof.
