Penelitian ini dimulai karena ditemukan bahwa siswa mengalami kesulitan mengkomunikasikan ide matematika di kelas matematika. Tujuan penelitian ini adalah untuk mengetahui bagaimana strategi pembelajaran problem pose diterapkan terhadap kemampuan komunikasi matematis siswa SMP Negeri 1 Mazo. Siswa SMP Negeri 1 Mazo kelas VIII semester I tahun ajaran 2023–2024. Siswa dibagi menjadi dua kelompok: kelas kontrol (VIII–2, dengan 20 siswa) dan kelas eksperimen (VIII–1, dengan 20 siswa). Tes kemampuan komunikasi matematika bergaya esai digunakan sebagai instrumen penelitian. Ujian tersebut dievaluasi secara teoritis sebelum versi final diujikan di SMP Negeri 4 Mazo untuk menjamin keabsahannya. Hasil uji hipotesis dengan thitung = 3,197 dan ttabel = 1,655 menunjukkan bahwa penerapan model pembelajaran problem pose mempunyai pengaruh yang signifikan terhadap kemampuan komunikasi matematis siswa. Karena thitung (3,197) lebih besar dari ttabel (1,655), maka hipotesis alternatif yang menyatakan penerapan model pembelajaran problem pose berpengaruh terhadap kemampuan komunikasi matematis siswa diterima.

Student academic performance is a key indicator of successful study program management. Detection of academic performance can help study program managers monitor and take proactive action against students who are potentially experiencing difficulties. Machine learning can be a solution to this challenge by assisting in the classification and detection of students' academic abilities. Machine learning techniques have proven to be very effective in analyzing complex data and uncovering hidden patterns that are difficult to detect by humans. This research aims to explore the implementation of machine learning algorithms in detecting students' academic performance, especially in the Mathematics Education Study Program at Nias University. With the advancement of technology, machine learning has proven to be effective in classifying data and detecting hidden patterns that traditional methods cannot identify. This research uses the Support Vector Machine (SVM) algorithm to predict student academic performance based on a dataset collected from student primary data. The dataset includes factors such as GPA, attendance, participation, and use of learning resources. The analysis results show that the SVM model used has an accuracy of 77.59%, with a bias that is more inclined to the class of students with good academic performance. The results of this study are expected to make a practical contribution in the development of more effective learning methods and personalization of academic interventions in higher education.

Faktor- faktor penyebab kemampuan berpikir kreatif siswa Kemampuan berpikir kreatif berkategori kurang disebabkan karena Siswa tidak memiliki minat, kesungguhan dan rasa ingin tahu dalam belajar matematika sehingga mengalami kebingungan dalam menentukan rumus yang akan digunakan, Siswa tidak paham pelajaran ketika guru menjelaskan dan Siswa tidak berani bertanya kepada guru. Kemampuan berpikir kreatif berkategori cukup disebabkan karena Siswa tidak terbiasa berlatih mengerjakan dan menjawab soal-soal dan Siswa cenderung masih menghafalkan atau meniru apa yang diberikan oleh guru, sehingga hal tersebut membuat siswa belum tampak berpikir orisinil dalam menyelesaikan suatu masalah. Kemampuan berpikir kreatif berkategori kreatif disebabkan karena adanya usaha siswa dalam memecahkan suatu masalah, Siswa berlatih mengerjakan soal-soal matematika dan adanya rasa kepercayaan diri siswa. Kemampuan berpikir kreatif berkategori sangat kreatif disebabkan karena siswa memiliki minat dalam belajar, Siswa sering berlatih mengerjakan soal-soal khususnya matematika dan Siswa berani bertanya kepada guru tentang soal yang tidak jelas. Penelitian ini menyarankan agar penelitian selanjutnya meningkatkan kemampuan berpikir kreatif siswa melalui latihan soal-soal sehingga siswa terbiasa menjawab soal- soal. Kata kunci: Kemampuan Berpikir Kreatif, Memecahkan Masalah Abstract This study aims to determine the creative thinking ability of 8th grade students of SMP Negeri 4 Gunungsitoli Selatan in solving math problems and the factors that cause students' creative thinking ability. This type of research is descriptive qualitative research. The subjects in this study were class VIII with a total of 26 students. Based on the results of the study, it shows that the creative thinking ability of students in class VIII of SMP Negeri 4 Gunungsitoli Selatan in solving math problems is quite creative where the average score is 51.3 and the number of students is 26 people. The factors that cause students' creative thinking abilities The ability to think creatively is categorized as less because students do not have interest, seriousness and curiosity in learning mathematics so that they experience confusion in determining the formula to be used, students do not understand the lesson when the teacher explains and students do not dare to ask the teacher. The ability to think creatively in the sufficient category is because students are not accustomed to practicing working and answering problems and students tend to memorize or imitate what is given by the teacher, so that this makes students not appear to think original in solving a problem. Creative thinking ability in the creative category is due to students' efforts in solving a problem, students practicing working on math problems and students' self-confidence. Creative thinking ability in the very creative category is due to students having an interest in learning, students often practice working on problems, especially mathematics and students dare to ask the teacher about problems that are not clear. This study suggests that further research should improve students' creative thinking skills through practicing problems so that students are accustomed to answering questions. Keywords: Students' Creative Thinking Ability, Solving Problems
