Abstract

Hidrolisis Garam merupakan salah satu konsep yang relatif dianggap sulit dan membingungkan bagi siswa. Salah satu sebabnya adalah karena konsep ini, berkaitan dengan konsep asam-basa, sebagai konsep prasyarat yang harus dikuasai siswa sebelum mempelajari Hidrolisis Garam. Materi Hidrolisis Garam yang dipelajari siswa kelas XI IPA di SMA dimaksud, mencakup konsep asam basa, persamaan reaksi, konsep mol, serta rumus-rumus perhitungan pH. Penelitian ini bertujuan untuk mendeskripsikan kemampuan pemahaman konseptual Hidrolisis Garam siswa kelas XI SMA di Gorontalo. Deskripsi penelitian ini dilakukan secara kualitatif, dari hasil analisis data 81 siswa sebagai subjek penelitian. Subjek ditentukan secara random dari beberapa SMA di Gorontalo. Data dikumpulkan mengunakan tes pilihan ganda Hidrolisis Garam, yang dikerjakan subjek secara tertulis. Hasil penelitian menunjukkan bahwa kemampuan siswa dalam menentukan sifat asam, basa, dan netral suatu senyawa, mencapai rata-rata 47%. Hasil ini makin menurun, di mana hanya ditunjukkan rata-rata 42% siswa yang dapat menentukan sifat garam yang mengalami hidrolisis. Demikian pula, hanya rata-rata 34% siswa yang dapat reaksi hidrolisis dari berbagai jenis garam ditinjau dari jenis reaksi dan dari hidrolisis (sebagian, total dan tidak terhidrolisis). Dan, hanya rata-rata 38% siswa yang dapat menentukan pH larutan garam yang terhidrolisis. Temuan ini mengindikasikan bahwa sebagian besar siswa yang cenderung mengalami miskonsepsi pada materi hidrolisis garam.

Abstract

This study aims to determine the critical thinking skills of high school students on salt hydrolysis. This research is quantitative descriptive. The population used in this study were all class XI IPA SMA in Gorontalo with a total sample of 64 respondents. Collecting data using a five-level multiple choice test instrument on salt hydrolysis material with an instrument validity value of 100%. The data analysis technique used in this research is descriptive quantitative. The results obtained the percentage of indicators of critical thinking skills, namely the focus criteria or Q1 level an average of 77.60%, the Reason criteria or Q2 level of 23.95%, the inference criteria or Q3 level of 8.85%, at Situation criteria or the Q4 level of 4.34% and the Clarity criteria or the Q5 level of 3.12%. Based on the results of the study it can be concluded that the ability of high school students to think critically on salt hydrolysis is 51.56% of students are in the very low category, 46.87% of students are in the low category and 1.56% of students are in the moderate category.

Abstract

The ability of students to understand and use concepts is the main key in scientifically explaining various chemical phenomena in nature. This ability develops relatively, often with the development of the learner level. This study aims to understand the level of understanding of the concept of salt hydrolysis of class XI high school students and chemistry students in the I, II, III and IV years and non-chemistry students with a total sample of 875 respondents. The instrument used in this study was a four-level multiple choice test. This diagnostic test combines the measurement of knowledge and reasoning with the level of self-confidence, as a reflection of the level of mastery of concepts. The data analysis technique used is quantitative, using SPSS 25 software, namely the non-parametric test (Kruskal Wallis test), comparing the significance value (Asmp. Sig) with a probability of 0.005. The results showed that the significance value of 0.00 was less than 0.05; That is, there is a significant difference in the level of understanding of the salt hydrolysis concept of students. The level of understanding of the concept of high school students is better than the first, second, third, and fourth year students in chemistry and non-chemistry students. These findings reinforce the story that although students have experienced learning experiences at a higher level, it does not guarantee the development of mastery of understanding the concept of hydrolysis
