Abstract

The material of particle dynamics, notably Newton second law, highly demands students’ ability to analyze and describe the directions of the certain force at one particular system as a mean to assist them in comprehending a concept. The teachers, who involve in the process of teaching the materials, need to choose a visual representation that is supported by other representation formats. Through this technique, students are demnded to comprehend the concept and solve the problems easier. The purpose of this research was to investigate the influence of free-body diagram representation skill towards the comprehension of the concept in particle dynamics material. In line with the purpose, the researcher decided One-Shot Case Study as the research design. Then, Sample class was selected by purposive sampling.The results of this research showed that there was a linear and significant influence of the free body diagram representation skill towards students’ concept comprehension. It was about 43,6%. The degree of relation between free-body diagram representation skill and concept comprehension had a strong relationship and its influence contributed positively.Keywords: Free Body Diagram Representation Skill, Inquiry Learning Model Multiple Representation Based, Concept Comprehension.

Abstract

Kali Wafor terletak di Distrik Biak Utara dan mengairi beberapa perkampungan yakni Dofyo Wafor, Warsansan, Kobeoser, Dernafi dan Sarwom, tujuan penelitian ini dilaksanakan  untuk mengetahui tingkat keanekaragaman jenis ikan dan kualitas perairan di Kali Wafor Distrik Biak Utara. Metode yang digunakan secara kualitatif dan kuantitatif. Analisis data secara kualitatif diolah dan dianalisis secara deskripitif dalam bentuk tabel dan gambar, sedangankan data kuantitatif diolah dengan menggunakan rumus Shanon Wienner, yakni dengan melihat indeks keanekargaman. Dari hasil penelitian diperoleh enam jenis ikan yang berhasil diidentifikasi. Sampel penelitian diambil dari tiga stasiun pengamatan. Dari hasil analisis data diperoleh nilai indeks keanekaragaman yang rendah. Tingkat keanekaragaman jenis ikan di Kali Wafor Distrik Biak Utara dipengaruhi oleh beberapa faktor diantaranya adalah suhu, DO (oksigen terlarut), pH, kecepatan arus, dan tingkat kecerahan perairan. Dari hasil pengamatan di tiga stasiun diperoleh hasil bahwa jenis ikan yang dijumpai pada dasarnya sama di setiap stasiun.
