Abstract

The low level of students' conceptual understanding in science learning remains a primary issue, as instructional activities often emphasize rote memorization and fail to optimally utilize digital media to support meaningful learning. This study aims to examine the role of digital media across the stages of the Discovery Learning model, identify the most effective types of digital media, and determine the characteristics of science topics that require technological support. The research method employed is a Systematic Literature Review (SLR) of 15 relevant articles published between 2020 and 2025. Data were analyzed thematically by grouping findings based on the role of digital media in the Discovery Learning stages, media types, science topics, as well as supporting and inhibiting factors in implementation. The results indicate that digital media such as PhET simulations, animated videos, interactive flipbooks, and augmented reality significantly enhance students' conceptual understanding by providing visual and interactive representations. These media are most effective for abstract topics such as energy, the solar system, and the digestive system. However, their implementation faces challenges, including limited school facilities, low digital literacy among teachers and students, and insufficient preparation time. The integration of digital media within the Discovery Learning model proves effective in concretizing abstract science concepts, with the novelty of this study lying in its comprehensive mapping of the relationships between media types, learning stages, and topic characteristics. Practically, these findings can serve as a guide for educators in selecting and designing digital media for more innovative instruction. Academically, this study encourages further research to address implementation challenges and to explore more personalized and adaptive technology integration for supporting quality science education.

Abstract

This research is motivated by the fact that students frequently experience misconceptions, particularly in distinguishing between temperature and heat, understanding the direction of heat transfer, and analyzing the relationship between heat and phase changes. This study aims to analyze the effect of using the Hydrostatics and Heat Kit on senior high school students’ conceptual change in the topic of heat. The use of the Hydrostatics and Heat Kit in heat instruction is expected to facilitate students’ conceptual understanding through concrete and direct experimental activities. This study employed an experimental method with a one-group pretest–posttest design conducted at SMA Negeri 1 Bolangitang. The research subjects consisted of two classes: an experimental class and a replication class, each with 30 students. A Three-Tier Diagnostic Test was used as the research instrument to identify students’ conceptual status, which was classified into Guessing (MB), Lack of Conceptual Understanding (TPK), Misconception (M), and Scientific Understanding (PK). Data were analyzed using descriptive quantitative analysis by comparing pretest and posttest results to identify patterns of students’ conceptual change. These patterns were represented by red arrows (↑) indicating improvement from misconception to scientific understanding, blue arrows (↓) indicating a decline in conceptual understanding, and yellow circles (O) indicating no conceptual change. The results showed that students in both classes experienced conceptual changes toward more scientific understanding, as indicated by the dominance of red arrows (↑). The most significant improvements occurred in differentiating between temperature and heat and in analyzing the relationship between heat and temperature changes during phase transitions. These findings support the Constructivism Conceptual Change theory, which emphasizes learning as a process of reconstructing initial conceptions into more accurate scientific concepts. Overall, the use of the Hydrostatics and Heat Kit within an Inquiry-Based Learning framework was effective in improving students’ conceptual understanding and reducing misconceptions about heat.

Abstract

Conflict between local communities and wildlife in the buffer villages surrounding Bogani Nani Wartabone National Park (TNBNW) continues to rise due to increasing human pressure on forest ecosystems. This study aims to identify the types of conflict, the wildlife species involved, and community responses to these disturbances. Data were collected through interviews with 30 respondents in East Suwawa and West Dumoga Subdistricts. Results show that most conflicts (90%) are triggered by wildlife perceived as agricultural pests, while 10% are caused by animals entering residential areas. Key species involved include the crested black macaque (Macaca nigrescens), Sulawesi wild boar (Sus celebensis), snakes, lowland anoa (Bubalus depressicornis), and various bird species. Reported disturbances range from crop damage and wildlife presence in farmlands to potential threats to human safety. Most community mitigation efforts are non-lethal, such as installing nets, using spiritus as a repellent, guarding fields with dogs, and setting simple traps. However, hunting still occurs in some areas for crop protection or economic purposes. Habitat loss from encroachment, logging, and land clearing exacerbates conflict by pushing wildlife out of forests into human landscapes. Overall, these findings demonstrate that human–wildlife conflict leads not only to economic losses but also threatens the survival of protected species such as Macaca nigrescens (VU), Sus celebensis (NT), and Bubalus depressicornis (EN). This study demonstrates scientific novelty by presenting an integrated empirical analysis of the forms of human–wildlife conflict, the composition of species involved, and community response patterns in buffer villages surrounding Bogani Nani Wartabone National Park that have not previously been systematically documented, and provides practical contributions by offering an evidence-based foundation for the development of adaptive, non-lethal, and community-based conflict mitigation strategies to support conservation area management and the protection of threatened species.

Abstract

Low learning outcomes, especially in IPAS subjects, are often caused by students becoming passive and disengaged in class when learning is dominated by lecture methods (teacher-centered). Thus, the purpose of this study is to investigate how well the Teams Games Tournament (TGT) model, combined with question-ball media, affects fourth-grade students' learning outcomes. In this study, a quantitative, one-group pretest-posttest design was used, with 24 students from SDN 03 Sidigede as the research subjects. The instrument in this study was a validated learning outcome test, and the data analysis involved normality testing and N-Gain analysis using IBM SPSS version 25. According to the analysis, using the TGT model with question-ball media improved student learning outcomes. This is indicated by the N-Gain values in the moderate improvement category for the concept understanding and skills processes, which are 0.57 and 0.54, respectively. These findings indicate that implementing the TGT model with the help of question ball media not only improves learning outcomes but also encourages active student participation in learning, strengthens learning motivation, and helps students understand IPAS concepts more contextually through game activities and group work.

Abstract

Motivation plays a crucial role in the integrated science learning process. Low learning motivation is often not due to limited ability but rather to a lack of encouragement. In integrated science learning, the human digestive system presents complex material that is difficult to visualize, resulting in decreased student learning motivation. This research aims to develop the Uno Dare Card learning media, which is feasible (valid, practical, and effective), to enhance students' learning motivation in the human digestive system material. The research method employed the ADDIE development model with 29 eighth-grade students from class VIII I of SMP Negeri 1 Martapura Kota as research subjects. The instruments used to collect data included test and non-test instruments. The research results show that the Uno Dare Card learning media is highly valid across content, presentation, language, and media feasibility, with an overall score of 0.943 in the highly valid category. The Uno Dare Card is also highly practical, and the Uno Dare Card learning media has been proven effective in enhancing learning motivation, with N-gain values in the high category. The Uno Dare Card learning media is valid, practical, and effective for teaching material on the human digestive system and for enhancing students' motivation to learn.

Abstract

Iron (Fe) contamination in Indonesian waters frequently exceeds the drinking water quality standard (0.3 mg/L) and poses risks to human health and aquatic ecosystems, highlighting the need for a selective and effective removal method. This study aimed to analyze the effect of solution concentration on the adsorption capacity of an EDTA-based Ion Imprinted Polymer (IIP) for Fe(III) ions. The research employed an experimental design through the synthesis of IIP using the precipitation polymerization method, with methacrylic acid (MAA) as the functional monomer, ethylene glycol dimethacrylate (EGDMA) as the crosslinker, and benzoyl peroxide (BPO) as the initiator. Data were collected through characterization using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy with Energy Dispersive X-ray (SEM-EDX), while Fe(III) concentrations were measured using Atomic Absorption Spectrophotometry (AAS). Fe(NO₃)₃ solutions at concentrations ranging from 5 to 35 ppm were tested at neutral pH. Data analysis was conducted by calculating the adsorption capacity as the difference between the initial and final concentrations. The results showed that increasing the initial concentration increased adsorption capacity until equilibrium was reached, with a maximum of 19.06 mg/g. FTIR analysis confirmed the presence of characteristic functional groups and the removal of Fe–O bonds after extraction, while SEM analysis revealed the formation of specific cavities in the IIP structure. In conclusion, the synthesized IIP demonstrates good selectivity and effectiveness for Fe(III) adsorption from aqueous solutions, indicating its potential application as a selective adsorbent for heavy metal-contaminated water treatment.

Abstract

Education is currently one of the most important aspects of human life. Education is the process of developing students' abilities. The importance of developing learning media is that using them can help students understand complex, abstract material more simply. This study aims to analyze the need for learning media in biology material at MA Darussalam Lempuing OKI. This study employed quantitative descriptive analysis techniques. Data collection used a questionnaire, with subjects being 11th-grade students and biology teachers at MA Darussalam Lempuing, OKI. The sample for this study consisted of 30 students. The analysis showed that only 23% of activities supported student collaboration, and that 60% of students' conceptual understanding remained low. This was influenced by the use of less engaging learning media, such as PPT (50%), YouTube (33%), and visual aids (17%). Furthermore, the teaching method used by teachers remained dominated by lectures (57%), leading to student boredom and disinterest. Thus, a flashcard learning media integrated with augmented reality is needed to improve students' collaboration skills and their mastery of concepts through the TGT model.

Abstract

Cigarette smoke contains nicotine compounds (C10H14N2), tar and carbon monoxide (CO), which cause inhibition of Leydig cells, damage to seminiferous tubules and damage to spermatozoa cells. The aim of this study was to determine the anti-infertility effect of Zinc supplements on the quality of Wistar rat (Rattus norvegicus L.) spermatozoa exposed to cigarette smoke. This research is an experimental study consisting of 4 treatments with 3 replications: Control (drinking water), P1 (14 mg/g BW), P2 (28 mg/g BW), and P3 (42 mg/g BW) Zinc. Exposure to cigarette smoke was carried out twice a day for 14 days in all treatments, and zinc was given for 14 days in treatments P1, P2 and P3. On the 29th day, mice were sacrificed by anesthesia using chloroform and dissected to observe the quality of spermatozoa with parameters of motility, viability and morphology. Data were analyzed using ANOVA (Analysis of Varience) and the BNT test with a 95% confidence level. The results showed that Zinc supplementation in treatments P1 and P2 significantly improved spermatozoa quality, whereas in P3 it decreased significantly. The conclusion of this study is that Zinc (Zn) supplements at a dose of 14 mg/g BW (P1) and a dose of 28 mg/g BW (P2) have an anti-infertility effect by improving the quality of rat spermatozoa that have been exposed to cigarette smoke. The results of this research can be important information for improving male reproduction due to exposure to free radicals from cigarette smoke.

Abstract

The Argument-Driven Inquiry (ADI) learning model is designed to provide students with opportunities to improve their methods of data collection, investigation, writing, answering investigative questions, and critical thinking. The ADI model also allows participants to participate in scientific debates and peer review. This study used a quasi-experimental one-group pretest-posttest design. Data were collected through a pretest and posttest comprising 10 essay questions, which were validated by expert lecturers and tested for validity and reliability. The data obtained from the tests were analyzed using test statistics, namely the Kolmogorov-Smirnov normality test, hypothesis testing, and n-gain analysis. The results showed that the average posttest scores in the experimental class across replications 1 and 2 were 84.5 and 83.7, respectively. Analysis using a t-test confirmed that the argumentation ability of class XI MAN 1 Boalemo students on the sound wave material taught using the Argument Driven Inquiry (ADI) model was significantly higher than the KKM of 70. The magnitude of the influence of the use of the Argument Driven Inquiry (ADI) model was also shown by the course average normalized gain per class, with the magnitude of the gain of the three classes consistently being in the high category, namely 0.77 for the experimental class, 0.77 for replication class 1, and 0.76 for replication class 2. The statistical test in this study shows that the calculated t-value (thitung) exceeds the critical t-value (ttabel) at the 5% significance level. This indicates a significant difference between students’ pre-test and post-test argumentation skills. These findings are consistent with various previous studies.

Abstract

Minimum Competency Assessment (MCA), known in Indonesia as Asesmen Kompetensi Minimum (AKM), is a national assessment of basic mastery that students must complete. Teachers must be able to compile MCA questions that accurately measure student knowledge. Well-written questions are crucial for creating high-quality assessments. This study analyzes the quality of MCA items on the topic of linear motion in science education at a junior high school in Surabaya. The study aims to evaluate multiple-choice questions using key psychometric parameters, such as validity, reliability, difficulty index, discrimination index, and distractor efficiency. The questions were created by the author and administered to 15 ninth-grade students on 8 May 2024. The analysis used descriptive quantitative methods, and data processing was performed in Microsoft Excel. The results showed that only 4 of 10 items were valid, and the overall reliability coefficient was low (KR-20 = 0.213). Based on the difficulty index, six items were categorized as moderate, three were difficult, and one was easy. The discrimination index analysis revealed that five items had good to excellent discrimination power, whereas others showed poor discrimination and required revision. Distractor efficiency analysis indicated that several distractors were non-functional, particularly in items with low discrimination indices. These findings imply that although some MCA items are suitable for use, many require improvement to ensure accurate, reliable, and diagnostic measurement of student competencies. The study highlights the importance of item analysis as a basis for improving the design of MCA-based assessments in science education.
