Abstract

Fenomena fisik rangkaian listrik menghasilkan model matematika dan solusi untuk penyelesaiannya. Rangkaian listrik orde dua adalah penggunaan persamaan differensial orde dua sebagai model persamaan matematika pada rangkaian listrik. Rangkaian tersebut diantaranya rangkaian LC seri dan RLC seri. Penelitian ini memaparkan analisis dan penyelesaian dari model matematika pada rangkaian listrik LC seri dan RLC seri menggunakan persamaan diferensial orde dua dengan solusi homogen maupun tak homogen.

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

Penelitian ini bertujuan untuk mengevaluasi sejauh mana aplikasi GeoGebra dapat membantu siswa SMP dalam memahami materi matematika, khususnya pada topik bangun ruang yang sering kali dianggap sulit karena konsepnya yang abstrak dan kurang mudah dibayangkan secara nyata. GeoGebra menghadirkan kemudahan melalui fitur visualisasi interaktif yang memungkinkan siswa untuk melihat dan memanipulasi bangun ruang secara langsung, sehingga konsep yang awalnya abstrak dapat menjadi lebih konkret dan mudah dipahami. Penelitian dilaksanakan pada 25 siswa kelas IX di SMP Citra Harapan, Kecamatan Percut Sei Tuan, dengan menggunakan desain pre-eksperimental satu kelompok. Para peserta didik menjalani rangkaian evaluasi yang terdiri dari tes awal sebelum menerima pengajaran dengan GeoGebra dan tes akhir setelah proses pembelajaran itu untuk menilai sejauh mana pemahaman mereka terhadap materi meningkat. Selain itu, siswa juga diminta mengisi angket sebagai bentuk evaluasi terhadap pengalaman dan respons mereka terhadap metode pembelajaran berbasis aplikasi GeoGebra. Hasil penelitian menunjukkan adanya peningkatan nilai yang signifikan setelah siswa menggunakan GeoGebra dalam proses pembelajaran. Hal ini membuktikan bahwa aplikasi tersebut efektif dalam membantu siswa memahami bentuk dan sifat bangun ruang dengan lebih jelas. Visualisasi interaktif yang disediakan GeoGebra membuat siswa dapat secara langsung mengamati perubahan bentuk dan sudut bangun ruang, sehingga konsep yang semula sulit menjadi lebih mudah dipahami. Selain dari segi peningkatan pemahaman, penggunaan GeoGebra juga memberikan dampak positif terhadap suasana belajar, di mana siswa merasa lebih tertarik dan antusias mengikuti proses pembelajaran. Mereka menjadi lebih terlibat dan terdorong dibandingkan dengan pendekatan pembelajaran tradisional yang hanya mengandalkan penjelasan konsep. Berdasarkan hasil tersebut, dapat disimpulkan bahwa penggunaan aplikasi GeoGebra sangat efektif sebagai media pembelajaran, terutama untuk materi matematika yang memerlukan visualisasi tinggi seperti bangun ruang. GeoGebra tidak hanya memperdalam pemahaman siswa, tetapi juga mendorong rasa ketertarikan dan antusiasme dalam belajar matematika. Oleh karena itu, disarankan bagi para guru untuk mengintegrasikan GeoGebra dalam proses pembelajaran agar dapat menciptakan pengalaman belajar yang lebih interaktif, menarik, dan efektif

Abstract

Multipurpose Cooperative (KSU) Deli Serdang Front Group 926 Saentis Village is a cooperative engaged in various business fields in Saentis Village which has difficulty in compiling a computer-based year-end report (RAT). Therefore, training and assistance are needed that aim to improve the skills of functionaries in preparing reports. The methods of training and mentoring at KSU are carried out in stages, meaning that each stage has different materials presented. This training and assistance is stage 2, namely stage 1 training for mothers who are members of cooperatives, namely sewing activities during the pandemic. Furthermore, because some of the functionaries did not understand computer-based data reporting, stage 2 was given training on how to understand something we already know and need to improve and something we have not mastered, namely in making year-end reports. The report was compiled based on ICT which aims to make the report valid and accepted at the annual member meeting. After training and mentoring, significant results were obtained where reports made based on metacognition and ICT were very valid and accepted at RAT.
