Abstract

This research aims to find out what factors influence the chemistry learning process at the Senior High School of 8 Mataram. The type of research used is descriptive qualitative, with the subjects 28 students of class XI MIA 6, 26 students of XII MIA 3, and 2 chemistry teachers. Data were collected using interview techniques with a validated interview guide sheet then worked interactively and carried out continuously until complete and clear where data analysis activities include data reduction, data presentation and conclusions/verification. Data validity was carried out by triangulating sources and time. The results showed that the factors that influence the chemistry learning process are the factors of teachers, students, learning facilities and infrastructure, and the social environment of students at school. There are 2 inhibiting factors that affect the chemistry learning process, namely student factors and learning facilities and infrastructure factors. Student factors that influence the chemistry learning process are readiness, interest and intelligence/ability of students to understand during the learning process. While the learning facilities and infrastructure factor is in the availability of laboratory tools and materials that are not complete and adequate. Teacher factors and the social environment of students at school are not an inhibiting factor that affects the chemistry learning process, because teachers have worked optimally, optimally and professionally in conducting learning. While the social environment of students at school shows a harmonious relationship between students and teachers, students with other students, and students with the school environment both inside and outside the classroom with cool and comfortable school environment conditions.

Abstract

This study aims to examine the impact of project-based learning supported by comic media on students' chemical science process skills in the experimental class XI MIPA at SMAN 1 Lembar, focusing on reaction rate material. The measured science process skills include observing, hypothesizing, planning experiments, using tools and materials, classifying, and communicating. Project-based learning is a method that emphasizes problem-centred instruction, problem-solving, decision-making, and collaborative opportunities for students. This quasi-experimental research employed a pretest-posttest control group design. From a population of 130 students, 62 samples were selected using a one-stage cluster sampling technique and divided into an experimental group (XI MIPA 1) and a control group (XI MIPA 2). Data analysis using N-Gain calculations revealed that the experimental class experienced a medium-level improvement (0.335), significantly higher than the control class's low-level improvement (0.011). Furthermore, the statistical analysis showed that tcount (3.15) exceeded ttable (1.671) at a 5% significance level, indicating that the use of project-based learning supported by comic media had a significant influence. The study concluded that while there was no significant difference between the pretest and posttest results of the two classes, project-based learning with comic media significantly enhanced the chemical science process skills of students in the experimental class compared to those in the control class, particularly for reaction rate material.

Abstract

The purpose of this study is to determine how the utilization of PhET multimedia virtual laboratory in interactive teaching materials impacts the acquisition of acid-base chemistry knowledge among grade XI students. This research was conducted through a pre-experimental design consisting of pre-test and post-test one group measurements. All students of class XI MIPA SMAN 1 Alas Sumbawa Besar constituted the population, while purposive sampling was conducted on class XI MIPA 3 consisting of 34 four students. Data collection instruments such as questions during the pre-test and post-test as well as survey sheets were valid and reliable for the purpose of data assessment. Both multiple choice questions and description questions have a high level of reliability, with values of 0.65 and 0.63 respectively. In addition, the average value of the Aiken V index for validity was found to be at the valid category level of 0.66. The questionnaire instrument used has a high level of reliability and validity with a value of 0.77 and high validity with the average value of the Aiken V index which is in the very valid category range with a value of 0.84. Data analysis techniques such as the N-gain test, normality test, and t-test were used to measure student learning outcomes, while reactions were assessed using the student interest test and resulted in an overall average N-gain value equivalent to a higher value scale. The pre-test significance (sig) value of 0.621 > 0.05 and the post-test value of 0.063 > 0.05 indicated that the pre-test and post-test data values were normally distributed, in accordance with the normality test results. The t-test resulted in a significance level of 0.000 < 0.05 (2-tailed). On the other hand, 74% of students' responses to the use of the materials fell into the interested group. The research findings show that the interest and learning outcomes of chemistry class XI IPA students of SMAN 1 Alas Sumbawa Besar are positively influenced by interactive learning materials based on virtual multimedia PhET lab on acid-base materials.
