Abstract

Penelitian ini bertujuan untuk mengetahui tingkat praktikalitas modul praktikum kimia kelas XI MIA SMAN 1 Lingsar yang dikembangkan. Jenis penelitian yang digunakan adalah penelitian dan pengembangan dengan menggunakan rancangan penelitian dari model pengembangan Thiagarajan yang terdiri dari 4 tahap pengembangan atau yang biasa disebut dengan model 4D (define, design, develop and disseminate). Populasi yang digunakan pada penelitian ini adalah siswa kelas XI MIA SMAN 1 Lingsar, sedangkan sampel yang digunakan adalah sebanyak 58 sampel. Teknik pengambilan sampel yang digunakan pada penelitian ini adalah proportionate stratified random sampling. Data tingkat praktikalitas modul praktikum yang telah diuji kelayakan dan reliabilitasnya dikumpulkan menggunakan angket dengan skala Likert. Empat indikator tingkat praktiklaitas yang diukur dalam penelitian ini adalah kemenarikan, kemudahan penggunaan, waktu pelaksanaan dan manfaat. Hasil penelitian menunjukkan bahwa tingkat praktikalitas modul pratkikum kimia dengan empat indikator tersebut masuk ke dalam kategori sangat praktis dengan presentase respon peserta didik sebesar 92.47% dan persentase repon guru kimia sebesar 94.85%.

Abstract

Learning difficulties are obstacles that hinder students from achieving optimal academic performance. This study aims to analyze the learning difficulties encountered by Grade XI students in chemistry and to identify the contributing factors. The research employed a descriptive method with a qualitative approach, involving 70 students from MAN 1 Central Lombok as research subjects. Data were collected using questionnaires, interview guides, and students’ test scores. The research instruments were validated by three expert validators, yielding a validity score of 0.88, indicating a high level of validity, and tested for reliability using Cronbach’s Alpha, which confirmed their consistency. Data were analyzed descriptively by calculating the percentage of learning difficulties based on specific indicators or criteria. The findings revealed that students faced major difficulties in calculation-based materials (60%) and theoretical concepts (54.06%). Interviews were conducted to strengthen the data obtained from the questionnaires. The contributing factors were categorized into internal factors, external factors, and learning approaches, with internal factors being the most dominant at 59%. This study is expected to serve as an evaluation material for teachers and schools in designing more effective and context-based learning strategies in chemistry education.
