Abstract
Sutri, 2025. Penerapan Model Problem Based Learning (PBL) untuk Meningkatkan Kemampuan Pemecahan Masalah Siswa pada Materi Fluida Statis di Kelas XI SMA Negeri 4 Kota Jambi : Skripsi Ilmu Pengetahuan Alam, FKIP Universitas Jambi, Pembimbing : (I) Dra. Astalini, M.Si., (II) Dwi Agus Kurniawan, S.Pd., M.Pd. Kata Kunci: Problem Based Learning (PBL), Kemampuan Pemecahan Masalah, Fluida Status, Penelitian Tindakan Kelas (PTK) Metode penelitian yang digunakan adalah Penelitian Tindakan Kelas (PTK) yang terdiri dari tiga siklus. Setiap siklus melibatkan tahap perencanaan, pelaksanaan, observasi, dan refleksi untuk mengukur efektivitas penerapan Problem Based Learning (PBL) dalam meningkatkan kemampuan pemecahan masalah peserta didik. Data dikumpulkan melalui tes kemampuan pemecahan masalah, observasi aktivitas guru dan peserta didik, serta angket persepsi siswaterhadap pembelajaran. Pada siklus pertama, model Problem Based Learning (PBL) mulai diterapkan dengan memberikan masalah nyata yang relevan dengan konsep fluida statis. Hasil tes menunjukkan adanya peningkatan, dengan nilai rata-rata mencapai 77,2 dan ketuntasan belajar sebesar 55,56%. Meskipun belum mencapai target yang diharapkan, siswa mulai menunjukkan keterlibatan yang lebih baik dalam diskusi. Namun, siswa masih mengalami kesulitan dalam mengidentifikasi konsep dan menyusun solusi terhadap permasalahan yang diberikan. Pada siklus kedua, model Problem Based Learning (PBL) ditingkatkan dengan pemberian bimbingan yang lebih intensif serta umpan balik dari guru. Hasil evaluasi menunjukkan adanya peningkatan ya ng cukup baik, dengan nilai rata-rata mencapai 81,4 dan ketuntasan belajar sebesar 72,22%. Siswa lebih aktif dalam diskusi dan lebih mampu memahami serta menerapkan konsep fisika dalam pemecahan masalah. Namun, masih terdapat beberapa siswa yang belum sepenuhnya mandiri dalam menyelesaikan permasalahan yang diberikan. Siklus ketiga menunjukkan hasil yang lebih optimal, di mana siswa semakin terbiasa dengan pendekatan Problem Based Learning (PBL) dan mampu berpikir lebih kritis dalam menyelesaikan masalah. Nilai rata-rata meningkat menjadi 85,2 dengan ketuntasan belajar mencapai 88,89%. Sebagian besar siswa (32 dari 36) berhasil mencapai standar ketuntasan. Selain itu, aktivitas siswa dalam diskusi dan keberanian siswa dalam menyampaikan pendapat juga mengalami peningkatan yang signifikan. Hasil ini menunjukkan bahwa model Problem Based Learning (PBL) dapat menjadi alternatif pembelajaran yang efektif dalam meningkatkan kemampuan pemecahan masalah siswa pada materi fluida statis. Hasil penelitian menunjukkan adanya peningkatan aktivitas guru dan siswa serta kemampuan pemecahan masalah siswa. Pada siklus I, ketuntasan klasikal siswa sebesar 55,56%, meningkat menjadi 83,33% pada siklus III. Model Problem Based Learning (PBL) efektif dalam meningkatkan kemampuan pemecahan masalah siswa. Sutri, 2025. Implementation of the Problem Based Learning (PBL) Model to Improve Students' Problem-Solving Skills in Static Fluids Material in Class XI of SMA Negeri 4 Kota Jambi: Undergraduate Thesis in Natural Sciences, Faculty of Teacher Training and Education, Jambi University. Supervisors: (I) Dra. Astalini, M.Si., (II) Dwi Agus Kurniawan, S.Pd., M.Pd. Keywords: Problem Based Learning (PBL), Problem-Solving Skills, Static Fluids, Classroom Action Research (CAR) This study employed Classroom Action Research (CAR), consisting of three cycles. Each cycle involved the stages of planning, implementation, observation, and reflection to measure the effectiveness of implementing Problem Based Learning (PBL) in enhancing students' problem-solving skills. Data were collected through problem-solving ability tests, observations of teacher and student activities, and student perception questionnaires regarding the learning process. In the first cycle, the Problem Based Learning (PBL) model was introduced by presenting real-life problems relevant to the concept of static fluids. The test results showed an improvement, with an average score of 77.2 and a mastery learning percentage of 55.56%. Although the expected target had not yet been achieved, students showed better engagement in discussions. However, they still faced difficulties in identifying concepts and formulating solutions to given problems. In the second cycle, the PBL model was enhanced with more intensive guidance and teacher feedback. The evaluation results indicated significant improvement, with an average score of 81.4 and a mastery learning percentage of 72.22%. Students became more active in discussions and demonstrated a better understanding and application of physics concepts in problem-solving. However, some students were still not entirely independent in solving the given problems. The third cycle showed optimal results, as students became more accustomed to the Problem Based Learning (PBL) approach and developed more critical thinking skills in problem-solving. The average score increased to 85.2, with a mastery learning percentage of 88.89%. Most students (32 out of 36) successfully met the mastery standard. Additionally, students' participation in discussions and confidence in expressing their opinions significantly improved. These findings indicate that the Problem Based Learning (PBL) model can be an effective alternative for enhancing students' problem-solving skills in static fluids material. The results showed an increase in both teacher and student activities, as well as students' problem-solving abilities. In the first cycle, the classical mastery level was 55.56%, which increased to 83.33% in the third cycle. The Problem Based Learning (PBL) model proved to be effective in improving students' problem-solving skills.
