Abstract

This study aims to analyze the level of student misconceptions and identify the factors causing these misconceptions regarding the topic of thermochemistry students at SMA Negeri 7 Kendari. This descriptive study employed a quantitative approach, involving 32 students from class XI Merdeka 5, selected via purposive sampling. The research instruments consisted of a 25-item two-tier multiple-choice diagnostic test, a questionnaire on the causes of misconceptions, and interviews. Data were analyzed descriptively using percentages. The results indicate an average student learning outcome score of 57.38, with the majority of students failing to meet the Learning Objective Achievement Criteria. Diagnostic test results revealed the following average distribution: 14.00% understood the concepts, 40.20% held misconceptions, 15.27% guessed, and 10.47% did not understand the concepts. The highest rates of misconception were found regarding the indicators of enthalpy change properties and bond energy (45.00% each), while the lowest rate was associated with the system and surroundings indicator (23.75%). Questionnaire analysis showed that the causes of misconceptions stemmed from internal factors specifically cognitive aspects (55%), learning interest (60.31%), and learning motivation (61.25%) as well as external factors, including school-related elements (61%) and environmental factors (54.45%). In conclusion, the level of student misconception regarding thermochemistry falls into the moderate category and is influenced by both internal and external factors.

Abstract

A study has been conducted on the inhibitory effect of non-polar (n-hexane) extract of Ladhangka leaves (Lunasia amara Blanco) against Escherichia coli bacteria. The purpose of this study is to find out the compounds contained in the non-polar (n-hexane) extract of Ladhangka leaves obtained through the extraction process and to determine the inhibitory effect of the n-hexane extract of Ladhangka leaves on the growth of Escherichia coli bacteria. The extraction was done using the maceration method with n-hexane as the solvent, followed by phytochemical screening, identification using Thin Layer Chromatography (TLC), compound analysis with Gas Chromatography-Mass Spectrometry (GC-MS), and antibacterial activity tests using the disc diffusion method at concentrations of 75%, 50%, 25%, and 12.5% during 24 and 48 hours of incubation. GC-MS analysis results identified 4 main compound components, namely 2-Propenyl, 2-propenoate, 5-cyclopropylidene-, 1-pentanol, 2,3,5-trimethyl-4-methylene-2-cyclopenten-1-one, and Methyl-ω-3 Arachidonate. However, antibacterial activity tests showed that the n-hexane leaf extract of Lunasia amara Blanco at all tested concentrations (75%, 50%, 25%, and 12.5%) was unable to inhibit the growth of Escherichia coli bacteria, as indicated by the absence of an inhibition zone (0 mm).

Abstract

The low chemistry learning outcomes of students on the colloid topic indicate the need for a learning model that actively engages students in the learning process. One alternative is the guided inquiry learning model integrated with a deep learning approach, which facilitates students in constructing concepts through systematic, meaningful, and active inquiry. This study aimed to determine the improvement of students' chemistry learning outcomes through the implementation of the guided inquiry learning model with a deep learning approach on the colloid topic. The research employed a quantitative approach using a pre-experimental method with a One Group Pretest–Posttest Design. The participants were Grade XI science students at SMAN 5 Kendari. The research instrument consisted of a learning achievement test administered before and after the treatment. Data were analyzed using descriptive statistics and N-Gain analysis. The results showed that the students' mean score increased from 22.6 on the pretest to 76.8 on the posttest. The average N-Gain score was 0.84, which falls into the high category. These findings indicate that the implementation of the guided inquiry learning model with a deep learning approach effectively improves students' chemistry learning outcomes on the colloid topic. Therefore, the guided inquiry learning model with a deep learning approach can be used as an effective instructional alternative to improve students' chemistry learning outcomes. ABSTRAK Rendahnya hasil belajar kimia siswa pada materi koloid menunjukkan perlunya penerapan model pembelajaran yang mampu meningkatkan keterlibatan aktif peserta didik dalam proses pembelajaran. Salah satu alternatif yang dapat diterapkan adalah model pembelajaran inkuiri terbimbing dengan pendekatan deep learning yang memfasilitasi siswa untuk membangun pemahaman konsep melalui proses penyelidikan secara sistematis, aktif, dan bermakna. Penelitian ini bertujuan untuk mengetahui peningkatan hasil belajar kimia siswa melalui penerapan model pembelajaran inkuiri terbimbing dengan pendekatan deep learning pada materi koloid. Penelitian menggunakan pendekatan kuantitatif dengan metode pre-experimental dan desain One Group Pretest–Posttest Design. Subjek penelitian adalah siswa kelas XI IPA SMAN 5 Kendari. Instrumen penelitian berupa tes hasil belajar yang diberikan sebelum dan sesudah perlakuan. Data dianalisis menggunakan statistik deskriptif dan uji N-Gain. Hasil penelitian menunjukkan bahwa nilai rata-rata hasil belajar meningkat dari 22,6 pada pretest menjadi 76,8 pada posttest. Hasil analisis N-Gain memperoleh nilai rata-rata sebesar 0,84 yang berada pada kategori tinggi. Hasil tersebut menunjukkan bahwa penerapan model pembelajaran inkuiri terbimbing dengan pendekatan deep learning efektif meningkatkan hasil belajar kimia siswa pada materi koloid. Temuan penelitian ini mengindikasikan bahwa model pembelajaran inkuiri terbimbing dengan pendekatan deep learning dapat dijadikan sebagai salah satu alternatif pembelajaran yang efektif dalam meningkatkan hasil belajar kimia siswa.
