Abstract

Abstract This study aims to develop  centrifugation tool to improve performance in the laboratory and problem solving skills. The research method used is Research and Development (R and D) with 4D model. The results showed that the developed centrifuge was declared according to the material, had educational value, was durable, precise in measurement, efficient and safe for students based on the responses of teachers and students respectively at 100 percent and 96.15 percent with very high criteria. Student performance scores in the laboratory have a distribution close to the average student performance score (91.52). The effectiveness of the application of centrifugation using the students worksheet obtained good results in improving problem solving skills with moderate criteria (0.60) and giving moderate effect (0.42). Based on these results, the developed centrifuge was declared effective for improving laboratory performance and problem solving skills. Keywords: centrifuge, student performance, problem solving. Abstrak: Penelitian ini bertujuan untuk mengembangkan alat sentrifugasi untuk meningkatkan kinerja di laboratorium dan keterampilan pemecahan masalah. Metode penelitian yang digunakan adalah metode Research and Development (R dan D) dengan model 4D. Hasil penelitian menunjukan bahwa alat sentrifugasi hasil pengembangan dinyatakan sesuai materi, memiliki nilai pendidikan, tahan lama, tepat dalam pengukuran, efisien serta aman bagi siswa berdasarkan tanggapan guru dan siswa masing-masing sebesar 100 persen dan 96,15 persen dengan kriteria sangat tinggi. Nilai-nilai kinerja siswa di laboratorium memiliki persebaran yang dekat dengan nilai rata-rata kinerja siswa (91,52). Keefektifan penerapan alat sentrifugasi dengan menggunakan lembar kerja siswa diperoleh hasil yang baik dalam meningkatkan keterampilan pemecahan masalah dengan kriteria sedang (0,60) dan memberikan pengaruh sedang (0,32). Berdasarkan dari hasil tersebut, alat sentrifugasi hasil pengembangan dinyatakan efektif untuk meningkatkan kinerja di laboratorium dan keterampilan pemecahan masalah. Kata kunci: alat sentrifugasi, kinerja siswa, pemecahan masalah.DOI: http://dx.doi.org/10.23960/jpmipa/v23i2.pp853-865
