Abstract

Indonesian government has recommended chemistry teachers to implement active learning models such as Jigsaw when teaching. Jigsaw learning model provides many benefits for students including the improvement of learning outcomes and the reduction of anxiety in learning science. However, the facts in the field show that the adoption of the Jigsaw learning is still minimal. Two constraints are the lack of knowledge and skills of chemistry teachers in using the learning model and the absence of training. Therefore, a training is needed to help chemistry teachers to be able to apply the Jigsaw learning model. The training has been carried out at SMAN 2 Muaro Jambi in 4 stages. Stage I is face-to-face lectures, stage II involves teaching practice, stage III is mentoring for the revision of the Learning Plan (RPP) based on the jigsaw model, and stage IV is evaluation. The evaluation results show that this training has been successful in improving teachers' knowledge and skills in applying the jigsaw model. Teachers are expected to continue using the jigsaw learning model when teaching chemistry. Abstrak. Pemerintah Indonesia telah merekomendasikan agar guru-guru kimia menerapkan model-model pembelajaran aktif seperti Jigsaw saat mengajar. Model pembelajaran jigsaw banyak memberikan manfaat bagi siswa meliputi peningkatan hasil belajar bahkan membantu siswa menurunkan kecemasan dalam belajar sains. Namun fakta dilapangan  menunjukkan penerapan model pembelajaran Jigsaw masih minim. Dua masalah penyebabnya adalah kurangnya pengetahuan dan keterampilan guru kimia dalam menggunakan model pembelajaran tersebut serta tiadanya pelatihan. Oleh karena itu, perlu dilakukan pelatihan untuk membantu guru-guru kimia agar mampu menerapkan model pembelajaran Jigsaw. Pelatihan tersebut telah dilaksanakan di SMAN 2 Muaro Jambi dalam 4 tahap. Tahap I adalah kuliah tatap muka, tahap II melibatkan praktek mengajar, tahap III adalah mentoring untuk revisi Rencana Pelaksanaan Pembelajaran (RPP) berbasis model pembelajaran jigsaw, dan tahap IV adalah evaluasi. Hasil evaluasi menunjukkan bahwa  pelatihan ini telah berhasil meningkatkan pengetahuan dan keterampilan guru dalam menerapkan model jigsaw. Guru diharapkan akan terus menggunakan model pembelajaran jigsaw saat mengajar kimia

Abstract

Identifying potential customers for term deposit products remains a challenge in the banking industry due to class imbalance in marketing datasets. This study proposes an integrated approach that combines Support Vector Machine (SVM) with the Synthetic Minority Oversampling Technique (SMOTE) and hyperparameter tuning via GridSearchCV to enhance prediction performance. The dataset comprises 45,211 records containing demographic and campaign-related features. Preprocessing steps include categorical encoding, feature scaling, and SMOTE-based resampling. The optimized SVM model achieves an accuracy of 91% and an AUC of 0.96, outperforming the baseline model and demonstrating strong discriminatory ability, particularly for the minority class. This method improves the balance between precision and recall while reducing bias toward the majority class. The findings confirm the effectiveness of combining SMOTE and SVM for imbalanced classification tasks in the financial domain. These results contribute to the advancement of applied machine learning in informatics, particularly in developing robust decision support systems for data-driven banking strategies. Future work may extend this approach to diverse datasets and explore advanced resampling or ensemble techniques to improve model generalization.

Abstract

Laporan keuangan yang disusun secara baik dan akurat dapat memberikan gambaran keadaaan yang nyata mengenai hasil atau prestasi yang telah dicapai oleh suatu perusahaan selama kurun waktu tertentu, keadaan inilah yang digunakan untuk menilai kinerja keuangan. Apalagi informasi mengenai kinerja keuangan suatu perusahaan sangat bermanfaat untuk berbagai pihak seperti investor, kreditur, pemerintah, bankers, pihak manajemen sendiri dan pihak-pihak lain yang berkepentingan. Tujuan dari penelitian ini adalah menganalisis pengaruh Net Profit Margin (NPM), Return On Equity (ROE), dan ukuran perusahaan terhadap harga saham Perbankan 2012-2018, sehingga dapat menjadi tolak ukur bagi investor dalam berinvestasi. Penelitian ini termasuk dalam jenis penelitian kausal komparatif, yaitu tipe penelitian dengan karakteristik masalah berupa sebab akibat antara dua variabel atau lebih. Berdasarkan sumber data penelitian ini termasuk dalam jenis penelitian sekunder yaitu suatu penelitian dimana peneliti tidak melakukan observasi langsung, namun hanya mengambil data yang disajikan pihak lain. Hasil Penelitian diperoleh Variabel Net Profit Margin (NPM) berpengaruh signifikan terhadap harga saham Perbankan. Variabel Return On Equity (ROE) berpengaruh signifikan terhadap harga saham Perbankan. Variabel Ukuran Perusahaan berpengaruh signifikan terhadap harga saham Perbankan.
