Abstract

Penelitian ini bertujuan untuk menganalisis kualitas pembelajaran matematika pada materi persamaan kuadrat dengan implementasi GeoGebra pada siswa SMA. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan desain studi kasus, serta pengumpulan data melalui tes dan wawancara. Hasil analisis menunjukkan bahwa siswa mampu memahami konsep persamaan kuadrat, mengidentifikasi metode pemfaktoran, dan menyelesaikan soal cerita dengan baik. Siswa juga dapat menerjemahkan masalah sehari-hari ke dalam model matematika dan menggunakan GeoGebra untuk memverifikasi jawaban. Meskipun demikian, siswa masih membutuhkan pendalaman dalam menjelaskan konsep secara sistematis dan cenderung lebih menyukai metode konvensional. Implementasi GeoGebra dalam pembelajaran ini menunjukkan potensi sebagai alat bantu yang menarik, namun belum sepenuhnya menggantikan metode pembelajaran konvensional. Penelitian ini menyimpulkan bahwa penggunaan GeoGebra dapat melengkapi pembelajaran matematika, tetapi perlu diintegrasikan dengan metode pembelajaran lain untuk mencapai hasil yang optimal.

Abstract

The issue of students' lack of discipline in public schools remains a major challenge in educational institutions. When disciplinary issues such as tardiness, failure to complete homework, skipping classes, and truancy are left unaddressed, they can disrupt the learning process and directly impact students' academic performance. This study aims to analyze the improvement of learning discipline among vocational high school students (SMKN) using behavioristic group counseling with self-management techniques to enhance student discipline. The research employed a quantitative approach with an experimental method. The design used in this study was a quasi-experimental design. The sample consisted of 195 students, from which 10 students were selected for the experimental group and 10 students for the control group, all of whom exhibited low levels of learning discipline. The sampling technique used was simple random sampling. Data analysis techniques included the Wilcoxon Signed Rank Test and the Kolmogorov-Smirnov 2 Independent Samples test. The findings revealed that group counseling services using a behavioristic 1approach with self-management techniques effectively improved students' learning discipline. These results provide practical implications for school counselors in delivering guidance and counseling services, particularly group counseling services, using a behavioristic approach with self-management techniques to systematically improve students' learning discipline.

Abstract

Jumlah kendaraan pribadi di Indonesia meningkat setiap tahunnya, peningkatan tersebut di dominasi oleh sepeda motor. Sayangnya, hal ini juga diikuti oleh meningkatnya jumlah kecelakaan kendaraan bermotor khususnya sepeda motor di Indonesia, yang korbannya di dominasi oleh generasi muda. Sosialisasi ini dilakukan untuk memberikan informasi lebih jelas tentang asuransi yang dapat mengalihkan risiko ketika terjadi kecelakaan lalu lintas. Pada sosialisasi tersebut ditemukan bahwa belum banyak peserta yang memahami asuransi kecelakaan. Melalui sosialisasi ini, diharapkan generasi muda memahami manfaat perlindungan finansia yang diperoleh. Sehingga, peserta sosialisasi dapat membuat keputusan yang cerdas tentang melindungi keluarga, aset, dan diri mereka sendiri. Selain itu, juga mengajarkan generasi muda tentang manajemen risiko, pentingnya perencanaan keuangan, dan membiarkan mereka melihat masa depan dengan lebih percaya diri.

Abstract

Random Forest memiliki versi modifikasi dan sejumlah hyperparameter yang terpasang “default” pada aplikasi. Penelitian terdahulu telah membahas bahwa penyetelan hyperparameter dapat berpengaruh terhadap kinerja sistem. Namun, penyetelan hyperparameter secara manual bukan pekerjaan yang sederhana untuk sebuah algoritma yang kompleks. Mempertimbangkan bahwa banyak dataset keamanan data yang berdimensi tinggi, maka otomatisasi dan efisiensi menjadi pertimbangan dalam pekerjaan ini. Penyetelan hyperparameter bertujuan membentuk kombinasi hyperparameter yang dapat meningkatkan kinerja prediksi. Penelitian ini memuat perbandingan kinerja evaluasi hasil prediksi dengan penyetelan hyperparameter. Hasil yang diperoleh pada pendeteksian spam dengan 3-fold dan 5-fold-cross-validation, variabel menunjukkan bahwa kinerja prediksi meningkat menjadi 95% dan 95.4% pada Accuracy  dan mencapai 98.5% dan 98.7% pada AUC, sementara ukuran tingkat kesalahan menurun hingga .50 dan .46  untuk MMCE dan .75 dan .80 untuk  Brier Score.Kata Kunci — penyetelan, hyperparameter, kinerja, prediksi.
