Telah dilakukan penelitian yang berjudul “Pengembangan Lembar Kerja Mahasiswa (LKM) berbasis Contextual Teaching and Learning (CTL) untuk Melatihkan Keterampilan Proses Sains (KPS) pada Materi Koloid”. Penelitian ini bertujuan untuk menganalisis kelayakan LKM, mendeskripsikan tanggapan mahasiswa, dan menganalisis KPS mahasiswa. Jenis penelitian yang digunakan adalah Research and Development (R&D) dengan model ADDIE yang terdiri dari lima tahap, yaitu analisis (analysis), desain (design), pengembangan (development), implementasi (implementation), dan evaluasi (evaluation). Subjek penelitian berjumlah 61 mahasiswa aktif angkatan 2021 dari Jurusan Pendidikan Kimia FKIP USK yang terdiri dari 57 mahasiswa perempuan dan 4 mahasiswa laki-laki. Teknik pengumpulan data dilakukan dengan observasi aktivitas, sikap, keterampilan, dan angket. Instrumen yang digunakan adalah lembar angket kebutuhan, lembar angket penilaian kelayakan LKM, lembar angket penilaian KPS mahasiswa, lembar angket tanggapan mahasiswa, dan lembar angket penilaian diri mahasiswa. Hasil penelitian menunjukkan bahwa hasil penilaian kelayakan LKM oleh 4 validator secara keseluruhan yaitu 92,05% dengan kategori “sangat layak”. Hasil penilaian KPS mahasiswa berdasarkan 10 indikator KPS terhadap pengembangan LKM secara keseluruhan yaitu 88,6%, dengan kategori “sangat baik”. Tanggapan positif yang diberikan oleh mahasiswa terhadap pengembangan LKM berdasarkan aspek kesesuaian LKM dengan materi kuliah kimdas II, kualitas tampilan LKM, bahasa dan kegunaan LKM secara keseluruhan yaitu sebesar 88,05%, dengan kategori “sangat baik”. Hasil penilaian sikap diri mahasiswa secara keseluruhan yaitu 68,15% dengan kategori “baik”. Berdasarkan hasil penelitian dapat disimpulkan bahwa LKM berbasis CTL untuk melatihkan KPS pada materi koloid sudah layak digunakan sebagai bahan ajar dan mahasiswa memberi tanggapan positif terhadap pengembangan LKM berbasis CTL untuk melatihkan KPS pada materi koloid.

A research has been conducted entitled "Development of Contextual Teaching and Learning (CTL)-based Student Worksheets to Practice Science Process Skills (KPS) on Colloidal Materials". This study aims to analyze the feasibility of the LKM, describe student responses, and analyze student KPS. The type of research used is Research and Development (R&D) with the ADDIE model which consists of five stages, namely analysis, design, development, implementation, and evaluation. The research subjects were 61 active students from the class of 2021 from the Department of Chemistry, FKIP USK, consisting of 57 female students and 4 male students. Data collection techniques were carried out by observing activities, attitudes, skills, and questionnaires. The instruments used were a needs questionnaire sheet, an LKM feasibility assessment questionnaire sheet, a student KPS assessment questionnaire sheet, a student response questionnaire sheet, and a student self-assessment questionnaire sheet. The results showed that the results of the MFI feasibility assessment by 4 validators overall were 92.05% with the "very feasible" category. The results of the student KPS assessment based on 10 KPS indicators on the overall development of MFIs are 88.6%, with the "very good" category. The positive responses given by students to the development of the LKM were based on the aspects of the conformity of the LKM with the Kimdas II course material, the quality of the appearance of the LKM, the language and the overall usability of the LKM, which was 88.05%, with the "very good" category. The results of the overall student self-assessment were 68.15% in the "good" category. Based on the results of the study, it can be concluded that the CTL-based LKM to train KPS on colloidal material is appropriate to be used as teaching material and students give positive responses to the development of CTL-based LKM to train KPS on colloidal material.
