Abstract

AbstrakPenelitian ini bertujuan mendeskripsikan dan menjelaskan kesulitan belajar siswa dan faktor-faktor penyebab kesulitan belajar siswa dalam mempelajari materi kelarutan dan hasil kali kelarutan. Subjek penelitian adalah 38 orang siswa dari seluruh kelas XII IPA. Metode penelitian yang digunakan adalah mixed method. Pengambilan data dilakukan dengan cara observasi, tes, dan wawancara. Analisis data yang dilakukan adalah analisis hasil observasi, analisis hasil tes diagnostik dan analisis hasil wawancara. Data yang diperoleh berupa hasil belajar siswa dan informasi mengenai faktor-faktor penyebab kesulitan belajar siswa pada materi kelarutan dan hasil kali kelarutan. Hasil penelitian menunjukkan bahwa bentuk kesulitan belajar siswa pada materi kelarutan dan hasil kali kelarutan adalah pemahaman materi prasayarat, menuliskan ionisasi garam, penggunaan rumus Ksp, pemahaman siswa pada konsep asam basa, pemahaman siswa pada konsep kesetimbangan kimia, pemahaman siswa pada penulisan persamaan reaksi, dan kemampuan operasi matematika. Faktor-faktor penyebab kesulitan belajar siswa yang disebabkan oleh faktor internal, meliputi: minat belajar kimia rendah, motivasi belajar kimia rendah, pemaknaan konsep siswa terhadap materi kelarutan dan hasil kali kelarutan rendah, pemahaman konsep prasyarat materi kelarutan dan hasil kali kelarutan rendah, dan kemampuan siswa dalam operasi matematika yang lemah. Faktor eksternal, meliputi: pengaruh negatif dari teman sebaya dan cara mengajar guru.Kata Kunci: kesulitan belajar, kelarutan dan hasil kali kelarutanAbstractThis study aims to describe and explain student learning difficulties and the factors that cause students' learning difficulties in learning the material solubility and solubility results. The research subjects were 38 students from all XII IPA classes. The research method used is a mixed method. Data retrieval is done by observation, tests, and interviews. Data analysis was carried out by analyzing the results of observations, analyzing the results of diagnostic tests and analyzing the results of interviews. Data obtained in the form of student learning outcomes and information about the factors that cause student learning difficulties in the material solubility and solubility results. The results showed that the form of student learning difficulties in the solubility and solubility results material was understanding pre-set material, writing salt ionization, using Ksp formula, understanding students on the concept of acid base, understanding students in the concept of chemical equilibrium, understanding students in writing equation, and mathematical operating abilities. Factors that cause student learning difficulties caused by internal factors include: low chemistry learning interest, low chemistry learning motivation, meaning of students' concept of solubility and low solubility products, understanding the concept of solubility material and low solubility results, and ability students in weak mathematical operations. External factors include: negative influence from peers and how to teach teachers.Keywords: learning difficulties, solubility and solubility results
