Abstract

Indonesia is an archipelagic country with more than seventeen thousand islands, both in the interior and border areas. The border area is directly or indirectly a barrier to other countries. The purpose of this study is to provide an overview for readers to conduct forecasting method research. This study aims to describe the profile of the spread of the virus and provide input on education policies in border areas for forecasting. This research may need to be more thematically up-to-date and slow in publication. Still, researchers believe this is useful for policymakers to determine policies from reading existing patterns using equations in forecasting methods. Especially in the era of disruption, which is full of uncertainty, knowledge like this is needed to make predictions. In this study, the characterization is divided into gender, age, occupation, and interaction. The results showed that the gender of COVID-19 patients in the border areas had the same proportion of both men and women, the age range of twenty to forty-eight years had a greater probability of being affected, employees/private sector were more dominant to be involved, groups and the most prevalent cause of transmission of COVID-19 is family interaction. In addition, using Brown's double smoothing exponential method shows that predictions for July, August, and November for suspects and patients with COVID-19 will increase. Thus, the recommendation from this research for the Education Office as a policy maker in border areas is that school learning activities should be postponed until conditions are feasible. Implementasi metode peramalan guna menentukan kebijakan model belajar mengajar saat pandemic di daerah perbatasanIndonesia merupakan negara kepulauan yang terdiri lebih dari tujuh belas ribu pulau, baik yang berada di pedalaman maupun di daerah perbatasan. Daerah perbatasan secara langsung atau tidak langsung menjadi pembatas dengan negara lain. Tujuan penelitian ini secara umum memberikan gambaran kepada para pembaca untuk melakukan sebuah penelitian metode peramalan. Secara kusus, dalam penelitian ini bertujuan untuk menggambarkan profil sebaran virus, dan memberikan masukan kebijakan pendidikan di daerah perbatasan atas peramalan yang dilakukan. Penelitian ini mungkin tidak up to date secara tema dan lambat dalam publikasi, namun peneliti berkeyakinan ini berguna bagi pengambil kebijakan untuk menentukan kebijakan dari membaca pola-pola yang ada menggunakan persamaan dalam metode peramalan. Apalagi di era disrupsi yang penuh dengan ketidak pastian, pengetahuan seperti ini sangat diperlukan untuk memprediksi. Dalam penelitian ini, karakterisasi dibagi menjadi empat yaitu jenis kelamin, usia, pekerjaan, dan interaksi. Hasil penelitian menunjukkan bahwa jenis kelamin pada pasien COVID-19 di daerah perbatasan memiliki proporsi yang sama baik laki-laki maupun perempuan, rentang usia dua puluh sampai empat puluh delapan tahun memiliki kemungkinan lebih besar untuk terkena, pegawai/swasta lebih dominan untuk terkena, kelompok lain dan juga penyebab paling dominan penularan COVID -19 adalah interaksi keluarga. Selain itu dengan menggunakan metode double smoothing exponential Brown menunjukkan bahwa prediksi Juli, Agustus hingga November kondisi suspek dan pasien COVID -19 akan naik. Dengan demikian, rekomendasi dari penelitian ini  untuk Dinas Pendidikan sebagai pengambil kebijakan di daerah perbatasan adalah kegiatan belajar di sekolah sebaiknya ditunda hingga keadaan sudah bisa dikatakan layak.

Abstract

With the rapid changes in the times, the emphasis in education has also shifted, from equipping students with highly codified knowledge to developing routine skills to empower them to face and overcome complex and non-routine cognitive challenges. Students must be able to think flexibly and creatively when asked to solve problems for which they do not yet have strategies. The purpose of this study was to describe the creative mathematical reasoning (CMR) abilities of students in solving multiple solution tasks (MSTs) in analytical geometry problems. The CMR indicators in this study were novelty, plausibility, and mathematical foundation. The research used a qualitative descriptive design, describing how students' CMR abilities and their own abilities in solving MSTs questions. The subjects of this study were second-semester students in the mathematics education program at a university in Subang in the 2024/2025 academic year. The subjects were given MSTs questions, grouped into high, medium, and low groups based on their scores. Then, two participants were selected from each group. The criteria for selecting research subjects were: fulfilling the CMR ability aspect; being able to solve several MSTs questions to assess novelty, plausibility, and mathematical foundation, including the stages of initiating reasoning, developing reasoning (incubation, illumination), verifying reasoning, and justifying reasoning; and being able to communicate well. The research subjects were divided into three groups based on the MSTs' question scores: high, medium, and low.  The results of the study illustrate that students' mathematical creative reasoning abilities in solving MSTs questions are not optimal, as reflected in the solutions they provide. Therefore, to optimize students' CMR abilities, assignments should combine question types and use interactive, practical, relevant, comfortable, and connected learning models. For example, project-based or technology-based learning models. Keywords: analytical geometry, creative reasoning, multiple solution tasks.

Abstract

Penilaian kualitas wine selama ini masih banyak bergantung pada evaluasi subjektif oleh panel ahli, yang berpotensi menimbulkan ketidakkonsistenan hasil. Penelitian ini bertujuan untuk mengembangkan sistem klasifikasi kualitas wine secara otomatis dengan memanfaatkan algoritma Support Vector Machine (SVM). Dataset Wine Quality Red yang bersumber dari UCI Machine Learning Repository digunakan sebagai objek penelitian, terdiri dari 1.599 data dengan 11 atribut fisikokimia. Tahapan penelitian meliputi proses standarisasi data menggunakan StandardScaler, pemodelan SVM dengan kernel Linear, Radial Basis Function (RBF), dan Polynomial, serta optimasi hyperparameter melalui Grid Search dan validasi silang 5- fold. Hasil pengujian menunjukkan bahwa kernel RBF dengan parameter optimal (C=100, gamma=0.1, dan class_weight='balanced') menghasilkan performa terbaik dengan akurasi sebesar 66,88%, nilai precision macro 0,519, recall macro 0,529, serta F1-score macro 0,514. Optimasi parameter dan penskalaan fitur terbukti mampu meningkatkan kinerja model secara signifikan. Dengan demikian, SVM berpotensi menjadi pendekatan yang efektif dalam mendukung klasifikasi kualitas wine secara objektif dan konsisten.
