Abstract

The purpose of this research is to produce valid, effective, and practical textbooks. In the short term, it aims to produce valid and practical teaching materials for linear algebra courses. Validity based on the relevance of the expected competencies i.e. 21st century competencies. Practicality is measured by the use of teaching materials in classroom learning. This study used a development research design, followed by four steps: 1) initial research, 2) prototyping, 3) summative evaluation, 4) reflection and documentation. In our initial research, we analyzed the need for teaching materials for the Information Systems study program, the reason being that students really needed linear algebra teaching materials that had applied concepts that were described visually that were easy to understand by students. In the prototyping stage, we write teaching materials according to the needs analysis. The prototype was discussed with experts, revised after summative evaluation and implemented during lecture meetings. The result is the final product in the form of teaching materials used during reflection. Our systemic documentation was written according to the established research framework. Finally, a valid, practical linear algebra teaching material has been produced

Abstract

Seiring dengan perkembangan teknologi pada penjualan air minum dengan kepuasan permintaan pelanggan dalam membeli air minum kesehatan alkali yaitu air minum yang dikonsumsi oleh tubuh yang mengandung mineral, memiliki rasa yang manis dan ringan, berbeda dengan air minum yang biasa dikonsumsi oleh konsumen. Mengingat penjualan air minum berbahan dasar alkali semakin meningkat di setiap daerah selama perkembangannya khususnya di wilayah Medan Johor dan sekitarnya. Saat ini masyarakat lebih memilih untuk mengkonsumsi air minum berbahan dasar alkali pH 8,5-9,5 karena membuat tubuh jauh lebih sehat, berenergi, dan vitalitas juga akan meningkat serta menghemat waktu dalam pemesanan. Peningkatan penjualan air minum “kangen water” juga disebabkan sulitnya mendapatkan air bersih untuk konsumsi di kota-kota yang kekurangan air bersih untuk konsumsi saat itu. Penelitian yang dilakukan bertujuan menganalisis penjualan air minum berdasarkan pada tingkat kebersihan air, kualitas pelayanan, harga, dan waktu pengisian air. Dalam hal ini penulis menganalisis Depot Air Minum “KangenWater” Kecamatan Medan Johor dengan analisis menggunakan metode Rough Set dan Regresi Linier. Metode ini diharapkan dapat mengetahui kepuasan pelanggan terhadap penjualan air minum “Kangen Water”. Analisis ini diharapkan dapat membantu mengetahui tingkat kepuasan pelanggan terhadap penjualan air minum. Dan dari hasil analisa tersebut dapat diketahui nilai jual produk Kangen Water yang diberikan kepada pelanggan sesuai dengan kriteria tingkat kepuasan.

Abstract

The use of computers at this time is commonly used by students in the field of research, such as managing research data using the help of SPSS software which can be completed accurately and precisely. However, this SPSS software has a large memory space, so there are a few problems with computers with small RAM, which means that it can be installed but the process is slow when used. The point is that you need patience. But compared to us having to calculate research data one by one, of course, it is not comparable. Therefore, it is important to provide training and assistance on how to install and use and manage research data with SPSS software. Based on this, the PKM University Potential Main Team provided training and assistance to Diploma III Health Analyst students at Nahdlatul Ulama University North Sumatra (UNUSU), because based on observations, the ability of students to manage data using the SPSS application was still low. The training will be held on November 5, 2022 by giving a pretest first. Then materials provide installation and input data on the work page and read the conclusions. The Post Test is given by giving practical questions directly on the computer. After evaluating the results of practice, it can be concluded that the training resulted in the ability of UNUSU Diploma III students to process data significantly better (increase) and students were highly motivated during the training

Abstract

One of the factors to the lack of success in the mathematics learning process is that the teacher does not innovate in applying the media in learning. In general, teachers at Budi Agung Private High School still apply conventional media so that students become passive and less interested in mathematics. This has an impact to the low student learning outcomes. Therefore, innovation in Adobe Flash-based learning is needed. The purpose of this study was to test the effectiveness of the use of Adobe Flash learning media on students' mathematics learning outcomes at Budi Agung Private High School, Medan. This study uses a quasi-experimental design. Data collection techniques consist of unstructured interviews, observation, documentation, and tests. The data analysis techniques used are the Liliefors test to test the normality of the data, the Levene test to test the homogeneity, the independent sample test, and the party test through one sample t-test to test the hypothesis. The population in this study were classes X-A and X-B SMA Private Budi Agung Medan, totaling 72 students, consisting of 35 students in the experimental class and 37 students in the control class. The results of this study were obtained through the results of the students' final test (post-test). The average post-test result of the experimental class students using Adobe Flash was higher than the control class using conventional methods, with namely the experimental class was 75.1 and the control class was 55.73. And based on the results of the t-test, it was obtained that tcount > ttable, namely tcount = 5.072 and ttable = 1.997 with a significant level of 5% from hypothesis testing Ha was accepted and H0 was rejected, which means that there is an influence on students' mathematics learning outcomes through Adobe Flash-based Learning media

Abstract

Cognitive conflict is a condition where students encounter new experiences that are not neatly arranged in their cognitive structure. The process of assimilation between old and new concepts in students' cognition. So to hone and improve students' cognitive abilities, it is necessary to have repetition aimed at training students' computational thinking skills which will affect their mathematical mastery. The purpose of this study was to see the effect of cognitive conflict on students' mastery of mathematical concepts. The research method is a case study with a qualitative descriptive and quantitative approach. Learning was carried out to 35 semester II students collaboratively in mastering integral concepts. Pretests are given to determine initial mathematical abilities, then problems are given and solved with computational thinking-based cognitive conflict strategies. The results obtained were very significant for moderate initial abilities, but for high initial abilities it did not affect it, for low initial abilities there was no response. The process that occurs during settlement is very conducive. Post-test results compared to pre-test there is a significant difference

Abstract

Kreativitas adalah kemampuan untuk mempergunakan imajenasi dari berbagai kemungkinan yang diperoleh dari interaksi dan ide atau gagasan orang lain untuk membuat koneksi dan  mendapatkan hasil baru dan bermakna. Kreativitas sangat penting, guru tanpa kreativitas pembelajaran di kelas akan terlihat monoton dan kurang bermakna. Oleh karena itu guru perlu mengembangkan daya kreativitas pada saat membuat media pembelajaran. Pelatihan membuat media pembelajaran berbantuan GeoGebra guru TK YP Tridaya Mandiri bertujuan memberikan motivasi dan arahan membuat media pembelajaran. Diberikan tutorial praktek langsung membuat animasi gerak berupa aktivitas yang menarik bagi anak usia dini. Dengan ketertarikan anak menjadi daya ingat dan sebagai informasi baru yang berguna untuk mengetahui seberapa jauh logika matematis anak terhadap gambar-gambar yang ada hubungannya dengan bentuk bentuk geometri. Setelah diberikan pelatihan selama satu hari dalam bentuk workshop kepada guru TK YP Tridaya Mandiri dan dilakukan evaluasi dengan tugas membuat animasi sesuai ide peserta pelatihan maka diperoleh hasil kreativitas guru sangat signfikan. Berdasarkan hasil angket yang dibagi kepada peserta pelatihan dan observasi pada saat proses pelatihan diperoleh gambaran tentang  motivasi dan antusias peserta pelatihan sangat baik.
