Hasil analisis awal keterampilan berpikir kritis peserta didik Fase E di SMAN 1 Pariangan menunjukkan penerapan model Problem Based Learning selama ini belum mampu mengembangkan keterampilan berpikir kritis dan kurangnya bekal pengetahuan serta keaktifan peserta didik. Tujuan penelitian ini adalah untuk mengetahui pengaruh penugasan mind map pada model Problem Based Learning terhadap keterampilan berpikir kritis peserta didik Fase E SMAN 1 Pariangan pada materi virus. Penelitian ini merupakan penelitian eksperimen dengan rancangan pretest-posttest control group design. Instrumen yang digunakan berupa lembar soal pretest-posttest dalam bentuk esai yang telah valid dan reliabel. Hasil penelitian diperoleh data nilai keterampilan berpikir kritis peserta didik kelas eksperimen lebih tinggi dari pada kelas kontrol. Uji paired sample t-test mendapatkan hasil bahwa penugasan mind map pada model PBL berpengaruh terhadap keterampilan berpikir kritis peserta didik fase E SMAN 1 Pariangan pada materi virus.

Abstract

Fingerprints are one of the biological characteristics that can be used to confirm the identification of ethnic fingerprint patterns. Fingerprint patterns are a biological variation that differs from one racial group to another, between women and men and even identical twins. One of the races/tribes in Indonesia is the Nias tribe. This research is descriptive research with qualitative methods. Descriptive research is research that aims to describe, describe a phenomenon according to conditions in the field. The sample for this research is all Nias students at SMA Negeri 1 Pinangsori in the 2023/2024 academic year. The results of research on identifying fingerprint patterns of the Nias tribe at Pinangsori can be concluded that the most common fingerprint patterns are loop-shaped fingerprint patterns, namely 93%, whorl-shaped 7% and arch-shaped 0%. Apart from that, based on gender and age grouping, namely boys (14-19 years) and girls (14-18 years), the most common fingerprint pattern, namely the loop fingerprint pattern, is owned by 59% of female students and 59% of female students. male education is 34%. The whorl fingerprint pattern is mostly owned by male students, namely 4% and 3% of female students, while the arch fingerprint pattern is not shared by the entire sample group of Nias ethnic at Pinangsori.
