Abstract

Gravity is a concept that is considered difficult for students and it is not uncommon for them to experience misconceptions about this concept. This study aims to analyze students' conceptions of the concept of gravity. The research was conducted at SMPN 1 Aikmel, West Nusa Tenggara, Indonesia. The sample consisted of 28 Class VIII students who were taken by simple random sampling technique. The instrument used is a standard test instrument used by TIMSS (Trends in International Mathematics and Science Study) by selecting content about the concept of gravity. Research data were analyzed using descriptive statistics. The results of the data analysis showed that only 32.14% of students were able to answer questions correctly. When compared with the average percentage of students at the international level for the same concept (Gravity), the number of students at SMPN 1 Aikmel is still below the international average (48.28%). This shows that the level of students' understanding of concepts at SMP 1 Aikmel is below the international average. This can be used as an illustration for teachers at SMPN 1 Aikmel and even for junior high school teachers in East Lombok Regency, considering that SMPN 1 Aikmel is the school with the second-highest National Exam (UN) scores in East Lombok.

Abstract

Penelitian ini bertujuan untuk mengetahui hasil uji instrumen penguasaan konsep fisika pada pokok bahasan elastisitas dan hukum Hooke. Metode penelitian yang digunakan adalah metode deskriptif. Populasi pada penelitian ini adalah instrumen penilaian penguasaan konsep fisika kelas XII MIPA di SMAN 1 Lembar. Adapun pengambilan sampel menggunakan teknik purpossive sampling dan dari empat kelas diperoleh peserta didik kelas XII MIPA 1. Teknik pengumpulan data menggunakan tes pilihan ganda sebanyak 30 soal untuk mengukur penguasaan konsep fisika peserta didik. Uji instrumen yang dilaksanakan yaitu uji validitas, uji reliabilitas, uji daya beda, dan uji tingkat kesurakaran. Berdasarkan hasil uji instrumen penguasaan konsep di SMAN 1 Lembar, diketahui bahwa untuk uji validitas dengan taraf signifikansi 5% diperoleh sebanyak 22 soal dalam kategori valid dan 8 soal dikategori tidak valid, untuk uji reliabilitas dengan taraf signifikansi 5% diperoleh 30 soal dalam kategori reliabel, untuk uji daya beda diperoleh 19 soal dalam kategori diterima, 4 soal dalam kategori diperbaiki dan 7 soal dalam kategori ditolak, untuk uji tingkat kesukaran diperoleh 14 soal dikategori mudah, 15 soal dikategori sedang dan 1 soal dikategori sukar.
