RapidMiner is an application that is used to analyze data quantities and qualitatively to obtain information and knowledge as expected. This software is implemented to process data using several methods or algorithms in Data Minig learning. However, when using this software, users sometimes cannot distinguish between various methods or algorithms in Data Mining. Therefore, it is necessary to evaluate to optimize the use of this software in data mining learning. This study focuses on RapidMiner evaluation of data mining learning using the Persiva model. This model consists of aspects of satisfaction, behavior, impact, and effectiveness. The data collection technique was in the form of a questionnaire with 48 subjects. Data analysis used is descriptive statistics to determine satisfaction, behavior and effects. Meanwhile, Think-Aloud Retrospective technique is used to determine the effectiveness of RapidMiner. Our findings show that users are satisfied with the results of respondents on average agreeing (80%), in the aspect of behavior and impact, the percentage results are above 80%, and the use of this application has been effective with a completion rate above 90%. So it can be concluded that by using this application in data mining learning users can easily complete tasks, and be motivated, and add insights and knowledge in relevant disciplines.

AbstrakPemanfaatan website banyak digunakan pada lembaga pendidikan, salah satunya di sekolah. Demi meningkatkan kinerja dan performa dari sebuah produk (website) tersebut, perlu dilakukannya evaluasi usability. Salah satu metode yang digunakan untuk mengevaluasi produk tersebut adalah dengan menggunakan metode usability testing. Penelitian ini bertujuan untuk mengetahui tingkat efisiensi, efektivitas dan kepuasan pengguna website SMKN 1 Praya menggunakan usability testing method. Jenis penelitian ini adalah kuantitatif dengan menggunakan pendekatan deskriptif. Populasi penelitian ini adalah seluruh siswa dan guru SMKN 1 Praya yang berjumlah 1543. Sedangkan jumlah sampel yaitu 10 orang. Teknik pengumpulan data pada penelitian ini menggunakan Performance Measurement, Retorspektive Think Alound (RTA), dokumen, dan kuesioner SUS (angket). Penelitian ini menunjukkan bahwa tingkat efisiensi website SMKN 1 Praya yang di ukur menggunakan mann withney u-test di peoleh hasil 1 ≤ 2 sehingga website SMKN 1 Praya di kategorikan tidak efisien. Efektivitas website SMKN 1 Praya sudah efektif dengan hasil succes sebesar 88,3%. Selanjutnya tingkat kepuasan pengguna website SMKN 1 Praya berada pada kategori good (bagus) dengan nilai SUS skor adalah 69,1≥68 dengan grade B. Rekomendasi perbaikan pada website SMKN 1 Praya adalah dapat menampilkan informasi mengenai data sekolah secara lengkap dan kegiatan untuk menunjang proses pembelajaran. AbstractUtilization of the website is widely used in educational institutions, one of them in schools. In order to improve the performance and performance of a product (website), it is necessary to evaluate usability. One method used to evaluate these products is usability testing method. This research aimed to know the level of efficiency, effectiveness, and satisfaction for users of the website of SMKN 1 Praya using the usability testing method. This research was quantitative descriptive. The populations were all students and teachers at SMKN1 Praya which consisted of 1543 people. The samples were 10 people. The technique of data collection of this research used Performance Measurement, Retrospective Think Aloud (RTA), documents, and SUS questionnaires (questionnaire). This research showed that the level of the efficiency on the website of SMKN 1 Prayawhich was measured by the man Whitney u-test obtained 1 ≤ 2 results so that the website of SMK 1 Praya was categorized inefficient. The effectiveness of the website at SMKN 1 Praya had been effective with success results of 88.3%. Furthermore, the level of satisfaction of users of website of Praya SMKN 1 was good category with a score of SUS score was 69.1≥68 with grade B. Based on the result of this research, the researcher Recommend the improvement of the website of SMKN 1 Prayaon case display the information of the school data completely and the school activities to support the learning process.

<p class="15cKeywordsBInggris"><span>The current condition of learning is carried out online based on government regulations to prevent the spread of the COVID-19 virus. Therefore, it is necessary to have android-based learning media (Belajar Asik) to make it easier for independent learning in their respective homes. This study aims to develop and find out the feasibility and user responses of Belajar Asik media in mathematics subjects. This type of research is Research and Development (R&amp;D) using the ADDIE development model with five stages, namely: Analysis, Design, Development, Implementation, and Evaluation. This research is limited to the implementation stage using limited tests and has not yet arrived at a test on a wide scale. Validation is carried out by material experts and media experts as many as two people each. The subjects in this study were 27 students, with data analysis techniques using a quantitative description. The findings are in the form of android-based cool learning media in mathematics learning. Validation results based on material experts obtained a very-feasible category (92%), while results from media experts obtained a feasible category (78%). Meanwhile, the results of students' responses to this media received a very positive response category (68%). Therefore, thus this application is feasible to use and can be applied as a learning medium in mathematics subjects’ trigonometric competencies class XI MA NW Kabar.</span><strong></strong></p>

Among other things, the teacher's tasks include planning and implementing the process of teaching and learning activities and evaluating student learning outcomes. The role of the teacher in learning is the educator, the model, and the instructor and tutor. Learning success is measured based on the achievement of competencies established since the beginning of the learning activities. Learning assistance at MA NW Lepak, which has been carried out by the PPM Hamzanwadi University team can increase student motivation, it is seen from 65% of students in the category of high and very high learning motivation. Learning outcomes increase after mentoring, viewed from learning outcomes with an increasing trend. The distribution of student learning outcomes in the excellent category from 17% increased to 26%, and the good category from 30% to 32%. Whereas for students whose categories failed to drop from 9% to 0%.
