Abstract. This study aims to determine the improvement of student’s problem solving skill after applying the problem based learning model and determine it’s effectiveness. This is a quantitative research with one group pretest-posttest design. Cluster random sampling was used, and 28 samples were obtained from one of high schools in Samarinda. The result of the analysis with Wilcoxon Signed Rank Test. The result showed that there’s a significant difference between students’ problem solving skill before and after the treatment, with the ­p-value 0,00 with significance 0,05. Generally, students’ problem solving skill increased from 8.5 to 29.5, with N-Gain of 0,2, which is classified as a low category. The highest gain was found in the ability of understanding the problem, with the ­N-Gain of 0,4, which is classified as a middle category. Meanwhile the indicator of students’ skill on planning problems, solving problems, and doing the re-check, were classified as low increasing category with N-Gain of 0,2. Based on calculation of effect size (d), which is 1,96 that is classified as a big category, the implementation of the treatment had a high effectiveness.   Keywords : Problem Based Learning, Problem Solving Skill, Simple Harmonic MotionAbstrak.

Lutut merupakan sendi utama penyangga beban tubuh. Kestabilan kerja sendi ini tergantung dari otot-otot dan ligamen-legamen disekitarnya.  Kekuatan muscular mulai merosot sekitar usia 40 tahun dengan suatu kemunduran yang dipercepat setelah usai 60 tahun. Tanda utama pada gangguan sistem muskuloskeletal adalah nyeri dan rasa tidak nyaman, yang dapat bervariasi dari tingkat yang paling ringan sampai yang sangat berat. Hasil wawancara dengan 10 orang lansia yang mengalami nyeri  lutut, ditemukan 7 orang lansia menggunakan obat farmokogi, 3 orang tidak mengkonsumsi obat-obatan tertentu. Dari 7 lansia yang menggunakan obat-obatan mengatakan sering merasakan efek samping dari obat yang dikonsumsi seperti mual dan diare dan merasakan efek ketergantungan. Jenis Penelitian penelitian pra-eksperimen dengan rancangan pra-test dan pasca-test menggunakan pendekatan penelitian kuantitatif dengan design Quasi dalam satu kelompok (one group pre-posttest design) untuk mengetahui kekuatan pengaruh kompres jahe terhadap intensitas nyeri lutut. Metode penelitian melakukan observasi langsung kepada responden dengan mengisi lembar observasi intensitas nyeri pretest dan Posttest dengan skala intensitas nyeri numerik (0-10). Data penelitian dianalisa dengan menggunakan wilcoxon signed rank test. Hasil penelitian didapatkan rata-rata (mean) intensitas nyeri sebelum diberikan kompres jahe sebesar 4,56 dengan standar deviasi 1,381. Rata-rata (mean) intensitas nyeri setelah diberikan kompres jahe sebesar 2,89 dengan standar deviasi 1,451. Dari hasil uji statistik didapatkan nilai p Value (α) sebesar 0,000, bahwa terdapat pengaruh kompres jahe dengan nyeri lutut pada lansia.
