Abstract

The teaching media that a teacher uses can have an impact on the comprehension and memory of the students. Chemical bonding material is one of the learning resources that educators are encouraged to employ to assist and promote more creative, engaging, and enjoyable learning experiences. Chemistry Edutainment media is one type of educational resource that can be employed. This study attempts to characterize student learning retention following chemistry lessons using chemistry edutainment on chemical bond material for class X MAN 3 Pontianak, as well as to ascertain the validity, practicality, and efficacy of chemistry edutainment media. The methods of measurement, observation, and interviewing are employed in the data collection process. Student learning outcomes assessments, observation sheets, and interview sheets were the instruments utilized to collect the data. The study employs the ADDIE method, yielding validation rates of 93.3% for the material aspect and 90.6% for the media aspect. These percentages denote a high level of validity. The practicality percentages, derived from the initial and main field trial questionnaire responses, are 87.17% and 94.03%, respectively, indicating a high degree of practicality. Moreover, the effectiveness analysis, based on the learning outcomes following the use of Chemistry Edutainment media, resulted in N-Gain scores of 0.92 and 0.71 for the initial and main field trials, respectively, meeting the high effectiveness criteria. The retention percentages obtained in the initial and main field trials are 75% and 89.97%, respectively, which meet the high retention criteria.

Abstract

This study aims to determine the effect of the Problem Based Learning (PBL) learning model on increasing Self-Esteem and student learning outcomes in the excretory system material. In this study, there are two types of variables used. First, the independent variable is the level of student self-esteem, and the dependent variable is the learning outcomes of students. The study was conducted at MTS Al-Misbah located at Jalan Desa Cipadung No.22, Cibiru District, Bandung City, West Java. The population in this study were all students of class VIII MTS Al-Misbah consisting of two classes, namely class VIII A and VIII B with a total of 73 students. The sampling method used was purposive sampling. The learning outcomes of students using the PBL model produced an N-gain of 0.7 with a high category. In addition, the results of self-esteem after using the PBL model got a high category, this proves that the learning model can affect the level of student self-esteem. The application of PBL in an effort to improve students' self-esteem is one solution where with this model students are more involved in the learning process so that it can improve students' self-esteem and learning outcomes. So, from the two hypothesis tests it can be concluded that there is an influence of the PBL learning model on improving students' Self-Esteem and learning outcomes in the excretory system material.

Abstract

Peat water in Indonesia, abundant in swamp regions, is acidic and rich in humic substances and Fe²⁺ ions, making it unsuitable for direct use. This study explores a sustainable approach to treating peat water using hydrogel synthesized from durian rind (Durio zibethinus), an agricultural waste rich in cellulose. Cellulose was extracted via alkali and bleaching treatment, then crosslinked with chitosan in a NaOH/urea solvent system to form a biodegradable, porous hydrogel. The hydrogel exhibited a swelling ratio of 857% and a gel content of 98.23%, indicating high hydrophilicity and network integrity. Adsorption experiments demonstrated removal efficiencies of 98.96% for methylene blue and 25% for Fe²⁺. The high dye removal at low concentrations suggests strong interaction between hydrogel functional groups (–OH, –NH₂) and organic molecules, while Fe²⁺ removal was attributed to electrostatic interaction and potential chelation. Adsorption followed pseudo-second-order kinetics, indicating chemisorption as the rate-limiting step. These results suggest that durian rind hydrogel is a promising low-cost material for organic and inorganic pollutant removal in acidic water systems. This study highlights the potential of agro-waste valorization in developing eco-friendly materials for water purification.

Abstract

The insufficient engagement of students in the learning process is linked to the utilization of teaching models and tools that fail to encourage direct involvement. Hence, there is a need to devise a learning framework that emphasizes active student participation. One potential strategy is project-based learning, integrating science, technology, engineering, and mathematics (STEM). This research aims to determine the effectiveness of the STEM-based 3D atomic theory teaching aids project on student learning outcomes. This research is a quantitative research with a pre-experimental design method type one group pretest-posttest with a sample of 30 class X SMAIT Al-Fityan Kubu Raya students taken using a purposive sampling technique. The data collection tools used were pretest and posttest and observation sheets. Testing the normality of the distribution of each pretest and posttest group using the SPSS 26.0 for Windows test. The results of the research show that there is an increase in student learning outcomes from 18% to 82% with an effect size value of 5.03 obtaining the Strong Effect category. This research shows that STEM-based 3D atomic theory teaching aid project learning is effective in improving student learning outcomes.

Abstract

The absence of self-learning resources tailored to the characteristics of students to study the identification of secondary metabolite functional groups based on research on medicinal plants in West Kalimantan necessitates the development of an e-module. This research aimed to develop an e-module based on Premna serratifolia research to identify functional groups in the Natural Products Chemistry course, ensuring its validity and practicality. The ADDIE model was followed, which included analysis, design, development, implementation, and evaluation stages, to develop this e-module. Data were collected using an indirect communication technique by distributing questionnaires. The research sample comprised 30 participants from Universitas Muhammadiyah Pontianak, Universitas Tanjungpura University, and Akademi Farmasi Yarsi Pontianak. The e-module was validated by nine validators, including subject matter experts, media experts, and language experts, with a validity score of 89.3%, indicating it is highly valid. The module was also found to be highly practical through individual, small-group, and large-group testing, with scores of 95.6%, 94.3%, and 98.3%, respectively. This research-based e-module is considered highly suitable and practical as a learning resource for identifying functional groups.
