Abstract

The aim of this research is to determine whether there are any misconceptions among first-year students regarding the concepts of heat and temperature. This study employs a descriptive research design. The sample used in this study consists of 224 first-year students from both public and private universities in the cities of Singkawang, Bima, Madiun, and the districts of Sumedang, Sintang, and Bandung. Data were collected through a g-form using a four-tier test instrument. The research results indicate that the percentage of misconceptions among students on the concepts of temperature and heat is highest in the sub-topic "Objects with higher temperature definitely have more heat content compared to objects with lower temperature," reaching 62.1%, and the lowest misconception in the sub-topic "Water at a temperature of 0°C has entirely turned into ice," reaching 40.6%. It is hoped that these findings can be utilized by lecturers and teachers in addressing the subtopic of heat and temperature, which is known to have many possible misconceptions. As a result, educators can employ effective instructional strategies to address their students' misunderstandings about heat and temperature

Abstract

This research aims to design practical learning for bioremediation of aquatic ecosystems from dye waste by utilizing enzymes extracted from baglog waste. The topic chosen was bioremediation of water polluted by acid blue 113. Purpose of this practicum is to provide in learning science by conducting a practicum that supports environmental sustainability. Variables in this study were enzyme extracts taken from baglog waste of brown oyster mushroom and the percentage of textile dyedecolorization. As a results showed that the percentage of decolorization of wastewater polluted by acid blue dye 113 was as follows: concentrations of 30 ppm (45.41%), 45 ppm (49.7%), 60 ppm (35.08%), and 75 ppm (23.09%). The enzyme extract of mushroom baglog waste can effectively degrade the content of acid blue 113 textile dye which is dissolved in water. This study is the first to be conducted in Indonesia which can be done easly and using available materials.

Abstract

Among the many things that can improve learning, self-efficacy gives a careful thought, especially in difficult subjects like science. This study aims to analyze the effect of reward and punishment system using Wordwall.net on students' self-efficacy in learning excretory system by using Transcript Based Lesson Analysis. This study used descriptive method conducted in a private school in Bandung. The data was collected through direct observation then will be analyzed based on observation sheet, the teachers' lesson plan, questionnaire, but mainly using the documentation from videos and voice recording to conduct the transcript-based lesson analysis. The results shows that rewarded students have higher engagement and involvement in the teaching and learning process, as well as the higher average value which is 68% categorized as good. In contrast, punished students have lower engagement and involvement in the teaching and learning process, as well as the lower average which 37% categorized as poor. However, the value of Pearson correlation is 0.065 which averages there is no significance correlation between. Thus, reward and punishment system still can be implemented in science learning even there is no correlation between reward and punishment system toward students' self-efficacy since there is still a positive impact towards students' self-efficacy as well as participation.

Abstract

This study explores the relationship between carbon dioxide (CO₂) concentration from paper combustion and temperature changes using a greenhouse effect simulation. Two desiccators were used: desiccator A with an LED lamp as an additional heat source, and desiccator B without an external heat source. The results showed that an increase in CO₂ in desiccator A significantly raised the temperature, demonstrating CO₂'s role in heat retention. However, in desiccator B, a temperature drop occurred due to the endothermic effects of paper combustion and water evaporation. These findings highlight the importance of external energy sources in manifesting the greenhouse effect and explain the complexity of the thermodynamic processes involved. This study contributes to a deeper understanding of CO₂-induced temperature changes and its relevance to global warming. The experiment can be used as an effective educational tool to introduce students to the greenhouse effect concept.

Abstract

Bone fractures are rising worldwide due to aging populations and increased trauma, creating demand for implants that overcome infection, delayed healing, and poor osteointegration. Multifunctional biomaterials, especially PLA–HA Bioxcrew systems, offer integrated mechanical support with antibacterial, anti-inflammatory, and osteogenic functions while remaining biocompatible. Implant-associated infections driven by Staphylococcus aureus and Gram-negative bacteria persist because of biofilm formation and chronic inflammation. Bioxcrew advancements address these barriers through metal-ion doping, nanoscale surface engineering, and incorporation of antimicrobial agents into biodegradable polymer matrices, enabling controlled ion release, immune modulation, stem-cell recruitment, and improved bone regeneration. Stainless steel provides strength, hydroxyapatite enhances biological integration, and PLA enables safe degradation and localized drug delivery, making their hybridization ideal for next-generation implants. Using a narrative–integrative review of peer-reviewed literature from 2018 to 2025, this study synthesizes trends in antibacterial strategies and regenerative performance. Findings show that hybrid Bioxcrew platforms significantly reduce infection risk and enhance functional bone healing.

Abstract

Electrolysis is a fundamental concept in electrochemistry, yet its real-world applications are often overlooked in classroom settings. This study aims to design and develop a rainwater electrolysis practicum tool that contextualizes electrochemical concepts, enabling students to directly observe chemical processes related to environmental issues such as acid rain. An experimental method was conducted by varying the applied potential difference (4, 6, 8, and 10 V) and measuring pH changes in rainwater. The apparatus was designed and fabricated by the authors, adapting established electrolysis principles into a hands-on practicum tool. The results indicate that increasing potential difference influences localized pH shifts, where the cathode environment becomes more basic while the anode becomes more acidic, visualizing ion distribution during electrolysis. Student responses, collected through questionnaires, revealed high levels of motivation, ease of use, attractiveness, and perceived usefulness of the practicum product. These findings demonstrate the effectiveness of the practicum in enhancing students' engagement and understanding of electrochemistry concepts. In conclusion, the rainwater electrolysis practicum developed in this study bridges the gap between theoretical knowledge and practical applications, fostering a contextualized learning experience that aligns with the objectives of science education while also embedding environmental relevance.

Abstract

The material on mixture separation is still challenging for students to grasp, students still do not fully understand the concept of chromatography. One way for students to gather information is by planning and carrying out experiments or practicum activities. The author wants to provide experience to students through experimental activities through separation of leaves pigments by paper chromatography with simple method. The method used is the development of an experiment-based practicum learning method on separation of mixture material which was carried out in class 7th grade students at junior high school level. The result of paper chromatography can separate pigments present in leaves. The pigments found in Iresine diffusa leaves are chlorophyll-a characterized by the green color, chlorophyll-b characterized by the yellow-green color, and carotene characterized by the orange color. However, the polarity of the solvent does not influence the Rf value in leaf pigments, as the range of Rf values remains consistent with other research results, even though the components of the solvent used are different. Students' responses, in terms of comprehension of the material and motivation to learn during this practical activity, also show high levels, with an average of 74.43%.
