Abstract

Currently the introduction and detection of heart abnormalities using electrocardiogram (ECG) is very much. ECG conducted many research approaches in various methods, one of which is wavelet. This article aims to explain the trends of ECG research using wavelet approach in the last ten years. We reviewed journals with the keyword title "ecg wavelet" and published from 2011 to 2020. Articles classified by the most frequently discussed topics include: datasets, case studies, pre-processing, feature extraction and classification/identification methods. The increase in the number of ECG-related articles in recent years is still growing in new ways and methods. This study is very interesting because only a few researchers focus on researching about it. Several approaches from many researchers are used to obtain the best results, both by using machine learning and deep learning. This article will provide further explanation of the most widely used algorithms against ECG research with wavelet approaches. At the end of this article it is also shown that the critical aspect of ECG research can be done in the future is the use of datasets, as well as the extraction of characteristics and classifications by looking at the level of accuracy.

Abstract

One of the causes of the unattractiveness of learning mathematics for high school is the complexity factor of learning media that is in harmony with complex material. Therefore, learning media need a form of presentation that is simple but attractive. Efforts to increase student interest, which require media to support learning mathematics. One of them is by using Geogebra learning media. This study aims to determine the influence of the use of learning media based on the Geogebra application on student learning outcomes at Senior High School 8 Cirebon. The research method used is a quasi-experimental design, which is a research method that has a control group, but cannot function fully to control external variables that affect the implementation of the experiment. The results of the study obtained the value of F-count > Ftable or 26,358 > 4,13. And the correlation (r) = 0.661 then it is included in the medium category. The coefficient of determination (r2) = 0.437 or 43.7%, then the learning media has an effect on student learning outcomes on the subject of trigonometric functions. Based on the results of the Independent T-test analysis, the t-count value of 11,037 using a significance level of 5% obtained t-table of 1,994. The t-table value is obtained from the excel program by means of =tinv(0.05;69.) then enter. Because the value of t-count > t-table (11.037 > 1.994) then Ho is rejected. This means that Geogebra learning media can improve student learning outcomes

Abstract

The existence of technological advances in the field of education does not rule out the possibility of negative things arising from the existence of e-learning. For students, the negative impact of based e-learningis a decrease in the affective or character aspects. Technological progress should be a bridge for the progress of the nation, in education to overcome the shift in character in students is to make e-learning a medium for character building. E-learning can be integrated with the implementation of strengthening character education programs (SCE). The program is implemented to reduce cases of moral degradation that are currently occurring among the community, especially teenagers, to optimize the use of technology in learning mathematics, and to implementation of SCE in based e-learning. This study uses a qualitative method with a case study approach. The instruments used are a self-assessment scale, peer rating scale, and interview guidelines for managing character education strengthening for students at SMPN 3 Plered. The results obtained are that most of the students (97%) have religious character values, honesty, responsibility, curiosity, discipline, independence, communicativeness, and tolerance. The obstacle experienced when implementation SCE in mathematics learning based e-learningis teachers and students lack of understanding and awareness regarding character education. Efforts made to minimize the obstacles experienced are to provide an understanding of character education for teachers and students, as well as provide direction to students who still do not have the awareness to instill character values in themselves.

Abstract

Motivation is one of the most important factors in influencing learning and learning outcomes for students at the kindergarten, elementary and junior high school levels.  However, in learning activities, it turns out that there are still students who are less active in participating in learning during the lesson.  Students or students still look lazy to learn.  Students also do not show their expressions that are happy and not enthusiastic in following ongoing learning.  Their attention is more focused on something that is opposite them than their learning tasks such as playing games in class and others. Learning motivation has a positive relationship with the learning outcomes of a subject. Thus, learning motivation contributes greatly to the achievement of student learning outcomes. Therefore, teachers must have the ability: (First) encourage learning motivation, (Second) directing learning motivation to achieve goals in achieving the learning outcomes of a subject, and (Third) strengthen learning motivation in order to ensure the consistency of students learning actions.
