Abstract

Kemampuan representasi matematis sangat penting untuk dimiliki dan dikembangkan. Penelitian ini bertujuan untuk menganalisis kemampuan representasi matematis siswa, serta bentuk representasi matematis yang muncul. Penelitian ini menggunakan studi kasus terhadap empat siswa SMP Kelas VII dengan kemampuan sedang, yang dilaksanakan dalam pembelajaran Mengenal Bentuk Aljabar. Penelitian dilaksanakan pada semester ganjil pada tahun ajaran 2022/2023 sebanyak tiga kali pertemuan. Adapun teknik pengumpulan data yang dilakukan yaitu angket, wawancara, dan lembar analisis pemecahan masalah. Hasil penelitian menunjukkan bahwa siswa kelas VII merupakan siswa tahap abstraksi awal sehingga kemampuan representasi matematis belum banyak muncul dan berkembang dengan baik. Adapun bentuk representasi yang muncul yaitu representasi simbolik dengan tipe rendah dimana masih terdapat Gap antara berpikir konkrit dengan kemampuan abstraksi awal. Beberapa hal yang mempengaruhi munculnya kemampuan representasi adalah motivasi yang tinggi dalam memecahkan masalah, metode belajar yang disajikan, dan kemampuan siswa dalam belajar matematika. Mathematical representation ability is very important to develop. This study aimed to analyze students' mathematical representation abilities, as well as the forms of mathematical representations that appear. This study used case studies of four Grade VII junior high school students with moderate abilities, which were carried out in Recognizing Algebraic Shapes. The research was carried out in the odd semester of the 2022/2023 academic year in three meetings. The data collection techniques utilized questionnaires, interviews, and problem-solving analysis sheets. The results showed that class VII students were students at the early abstraction stage, so their mathematical representation abilities had not emerged and developed well. The form of representation that appears was symbolic representation with a low type where there was still a gap between concrete thinking and initial abstraction abilities. Some of the things that influenced the emergence of representational abilities were high motivation in solving problems, the learning methods presented, and students' abilities in learning mathematics.

Abstract

The aim of this research is to find out the level of students' preparedness for earthquake disasters. This type of research is qualitative descriptive research with a survey method with the population being junior high school students where schools are selected based on several conditions, two schools were selected. The total number of respondents taken from 2 schools, SMPN 2 and SMPN 4 Tanantovea, was 49 students. Data were taken from a questionnaire that had been modified by the author. The results of the research show that the knowledge aspect of SMPN 2 students is in the low category of 14%, for SMPN 4 the percentage of 14% is also in the low category, the emergency response plan aspect of SMPN 2 students is in the low category of 12%, for SMPN 4 students is in the low category. 15% in the low category, the early warning aspect of SMPN 2 students in the percentage of 14% in the low category, for SMPN 4 students in the percentage of 13% in the low category, and the resource mobilization aspect of SMPN 2 students in the percentage of 15% in the low category, and for SMPN 4 students in the the percentage of 16% is in the low category. So the overall results conclude that students' preparedness in facing earthquake disasters at the junior high school level in Tanantovea District, Donggala Regency is still in the low category.
