Abstract

Renewable energy learning in science education requires contextual teaching materials that connect scientific concepts with local environmental issues and future-oriented skills. However, current classroom practices still face limitations in integrating project-based learning, socio-scientific issues, and entrepreneurial-oriented activities into structured learning resources. This study aimed to analyze the needs for developing a STEM-PjBL-SSI-based electronic student worksheet (e-LKPD) on renewable energy using oil palm empty fruit bunch waste as a local biomass context. A descriptive quantitative approach was employed through a survey involving 29 science teacher respondents. The data were collected using a questionnaire and analyzed descriptively using percentages. The results showed that Problem-Based Learning was the most frequently used learning model, applied by 51.7% of respondents, followed by Project-Based Learning at 37.9%, Discovery Learning at 27.6%, and Inquiry-Based Learning at 10.3%. The most commonly used teaching methods were discussion at 62.1% and experiment at 58.6%, while lectures were still used by 34.5% of respondents. In terms of learning resources, teachers mostly used learning videos at 72.4%, the internet at 65.5%, reference books at 55.2%, modules at 48.3%, and student worksheets at 44.8%. The findings also revealed that 62.1% of teachers were familiar with Socio-Scientific Issues, while misconceptions regarding renewable energy sources were still found among some respondents. Although 75.9% of teachers developed their own student worksheets, the existing worksheets had not systematically integrated STEM, project-based activities, socio-scientific issues, and entrepreneurial skill development. Therefore, the development of STEM-PjBL-SSI-based e-LKPD using oil palm empty fruit bunch waste as a renewable energy context is needed to support more contextual, interactive, and skill-oriented science learning.

Abstract

The increasing number of motor vehicles has been accompanied by a rise in vehicle-related crimes, highlighting the need for more advanced and adaptive security systems. Conventional vehicle security systems are limited by their inability to provide real-time monitoring and accurate intrusion detection. This study aims to develop and evaluate an Internet of Things (IoT)-based vehicle security system that integrates multiple sensors to improve detection accuracy and responsiveness. The research employs a Research and Development (R&D) Level 3 approach, involving system design, development, and performance testing. The proposed system utilizes a combination of piezoelectric sensors for vibration detection, glass break sensors for acoustic detection, and a GPS module for real-time tracking, all controlled by an ESP32 microcontroller and connected to a Telegram-based notification system. The results indicate that the multi-sensor integration enhances the system’s ability to detect various intrusion patterns more accurately while minimizing false alarms compared to single-sensor systems. Additionally, real-time notifications and location tracking improve user responsiveness to potential threats. In conclusion, the developed system provides a more effective, accurate, and adaptive vehicle security solution suitable for modern security challenges.

Abstract

This study profiled the critical thinking disposition of early-year science education students and examined preliminary psychometric evidence of an Ennis-based questionnaire. A quantitative descriptive survey with preliminary psychometric analysis was conducted with 90 second-semester science education students from three universities in West Nusa Tenggara Province, Indonesia. Data were collected using a 36-item questionnaire organized into 12 indicators of critical thinking disposition. Negatively worded items were reverse-scored before analysis. Descriptive statistics, category distribution, indicator-based profiling, Cronbach’s alpha, corrected item-total correlation, and exploratory factor analysis based on 12 indicator scores were applied. The results showed that students’ critical thinking disposition was generally moderate, with nearly all participants located in the moderate category. The highest indicator scores were found in precision required by situation, total situation, and employing critical thinking abilities, while the lowest scores were found in clear reasons, credible sources and observations, and being well-informed. The corrected internal consistency was modest, and several negatively worded items showed weak item-total correlations. The exploratory factor analysis suggested a tentative three-factor structure: evidence-based reasoning disposition, contextual and reflective judgment, and self-regulated critical engagement. These findings indicate that students’ critical thinking disposition is still developing and that the questionnaire requires further refinement.

Abstract

Chili farmers in Kendalbulur Village are the main subjects that have a great influence due to exposure to pesticide residues (toxicity). Pesticide toxicity affects enzymes produced by the liver that cause changes in its working system. This study aims to look at the characteristics and levels of the enzymes SGOT, SGPT, and ALP in chili farmers exposed to pesticides that perform spraying activities. The SGOT-SGPT liver function test is a health screening that combines the examination of SGOT and SGPT enzyme levels in the blood. The purpose of this liver function test is to detect hepatitis or cirrhosis of the liver in chili farmers. The alkaline phosphatase (ALP) enzyme test is conducted to help diagnose and evaluate cirrhosis and inflammatory diseases of the liver. In addition to evaluating liver function, the alkaline phosphatase (ALP) enzyme test can also help detect bone disorders or protein deficiencies in chili farmers. Respondents were 20 chili farmers and pesticide users with an age range of 34–71 years. Test method using the non-analytical descriptive method and sampling technique using total sampling. The examination carried out is the rate of SGOT, SGPT, and ALP using spectrophotometry. The results of the SGOT examination showed that all respondents had SGOT levels in the normal range of <40 U/L, where the lowest result was 16 U/L and the highest was 35 U/L. While SGPT showed that all respondents were in the normal range of 40 U/L, with the lowest result of 2 U/L and the highest of 23 U/L, the ALP levels of many respondents were above normal values. The lowest value is 131 U/L, and the highest is 222 U/L. The results showed that the respondents showed disruption of the liver because ALP levels give high results. Where should ALP levels decrease with age.

Abstract

Misconceptions persist and hinder the achievement of learning goals. The purpose of this study is to identify and explain issues that arise when students attempt to comprehend the circulatory system concept. A multiple-choice questionnaire based on the Four-Tier Diagnostic Test question model that has been validated serves as the instrument. Students have the validity tested by distributing it and using the R-Table is greater than the R-Count. Three experts delivered an average value of 0.73, which was then used in Aiken's Test. The study reveals that the majority of students (36.2%) have a low level of understanding of the human circulatory system. This is due to students' tendency to memorize scientific terms and difficulty understanding the system. The percentage of students in the FP and FN categories is relatively low, with 14.9% and 10.2% respectively. This suggests that students' understanding of the concept is similar to the percentage of M (27.6%). SK, which comprises 11.1% of overall student responses, is the lowest compared to LK, M, and collaboration of FP and FN categories. This low SK percentage can be attributed to limited hands-on activities, inadequate teaching methods, and insufficient emphasis on the circulatory system's importance in overall health.

Abstract

This study aims to identify students' learning styles, assess their science problem-solving abilities, and analyze these abilities in relation to their learning styles on the topics of vibration, wave, and sound. Employing a quantitative descriptive approach, data were collected through tests, observations, and interviews. Instruments included a learning style questionnaire, problem-solving ability test, and interview guidelines. The findings reveal four learning styles among students—visual (25%), auditory (13%), kinesthetic (58%), and visual-kinesthetic (4%)—with kinesthetic being the most prevalent. However, 71% of students demonstrated low science problem-solving ability, with an average score of 52.9. Specifically, problem-solving performance was categorized as low across all four indicators: understanding the problem (36.5%), planning the solution (29.2%), implementing the solution (29.7%), and rechecking the answer (18.3%). Students with visual learning styles performed better in all problem-solving stages compared to their auditory and kinesthetic peers. This study highlights the need for tailored teaching strategies to improve problem-solving skills, particularly for students with auditory and kinesthetic learning styles, as no prior research has focused on the interplay between learning styles and problem-solving abilities in the context of vibration, wave, and sound materials.

Abstract

This research aimed to produce feasible and practical teaching modules on grade X chemical bonding topic based on Technological Pedagogical Content Knowledge (TPACK) and Culturally Responsive Transformative Teaching (CRTT). It is a Research and Development (R&D) using the five-step Borg and Gall model. 36 students from class X at SMAN 1 Narmada participated in this study’s limited trial. Data collection techniques used validation instruments and practicality questionnaires. Aiken’s V index which measures the validity of six aspects including aspects of content feasibility, aspects of suitability for the learning model, aspects of cultural suitability, language, assessment, and completeness of attachments, obtained an average value of V = 0,89 which indicates that the TPACK and CRTT-based teaching module is classified as very valid. The feasibility of the validation results of the teaching module includes six aspects of assessment, with the acquisition of scores in each aspect including; the aspects of content eligibility, suitability with the learning model, cultural suitability, language, assessment, and completeness of attachments obtained an average score of 0.95 consecutively; 0,83; 0,91; 0,83; 0,83; and 1.00. Meanwhile, the practicality test of teaching modules based on teacher responses on the aspects of ease, practicality, attractiveness and benefits of teaching obtained an average practicality of 90% classified as very practical, with four aspects of assessment by teachers, namely ease of use, practicality, attractiveness, and benefits that obtained an average score of 84%; 92%; 92%; and 93%  respectively. Students’ responses on the aspects of presentation, ease of use and benefits of learning devices obtained an average practicality of 83% classified as practical, with an assessment of three aspects, namely media presentation, ease of use of media, and benefits, the average practicality of each was 83%; 82%; and 84%. Thus, it can be concluded that the TPACK and CRTT-based teaching module on the topic of chemical bonding class X SMAN developed is feasible to use in terms of validity and practicality. TPACK and CRTT-based development research is more carried out on the development of e-modules, LKPD for students has not developed many TPACK-based and CRTT-based teaching modules. In addition, previous research has integrated PBL, discovery learning, and PjBL models in developing a teaching material on chemical equilibrium, colloid, and others using 4D and ADDIE development models.

Abstract

Climate change is a critical global issue with complex and far-reaching impacts that extend beyond the environment to include social, economic, and health dimensions. Addressing these challenges requires future professionals, such as forestry students, to develop strong analytical thinking skills, particularly in identifying and formulating environmental problems. Despite the growing recognition of climate change, limited research exists on forestry students’ understanding and analytical response to this issue, especially within specific regional contexts such as West Nusa Tenggara (NTB), Indonesia—a region particularly vulnerable to climate-related effects. This study aims to examine the level of awareness among forestry students regarding climate change issues in NTB and to evaluate their problem-identification and problem-formulation skills based on the phenomenon of global warming in the area. The novelty of this research lies in its regional focus, as NTB is seldom featured in climate literacy studies despite its unique climatic challenges. Using a descriptive quantitative method, data were collected from 26 forestry students enrolled in a Basic Chemistry course through an essay-based test administered in October. The variables observed were environmental awareness, problem-formulating ability, and problem-identifying ability. Data analysis was conducted descriptively and presented in tables and graphs. Results showed low student performance across all variables, with mean scores of 44.6 (awareness), 50.96 (problem formulation), and 40.76 (problem identification). These findings underscore the urgent need for strategic, problem-based educational approaches to improve students’ climate awareness and analytical competencies, ultimately preparing them to effectively contribute to sustainable environmental solutions in their future professional roles.

Abstract

The purpose of this study was to describe the mathematical ability of grade VIII students at SMP Negeri 2 Sungai Keruh, Musi Banyuasin Regency in solving problems on the material of straight line equations by using the context of school cooperatives where school cooperatives provide an authentic context-based learning environment, allowing students to directly apply the concepts they have learned, including in the field of mathematics. Students' ability to solve mathematical problems plays an important role in determining the level of student success in learning. The subjects this study involved 30 students who were class VIII students. To describe in depth the students' ability to solve problems, a comprehensive approach is needed that not only includes the final results, but also the thought processes and strategies they use in solving these problems. With descriptive method and qualitative approach is the type of this research. The tool instrument in this study used in the form of an instrument to do a test on the ability solve mathematical problems with the material straight line equations as much as 2 activities of problem test activities and in the form of interviews. The level of students' ability to solve math problems at each Polya stage is as follows. 27% of students are categorized as high ability, 50% of students with medium ability and 23% of students with low ability to solve problems. In general, this situation illustrates that students' ability to solve mathematical problems is at a moderate level. These results illustrate that students' ability to solve mathematical problems can be improved through a more contextualized direct approach where problem-based learning helps students understand mathematical concepts by linking theory to real situations, encouraging students to think critically in solving problems directly using problems that are very relevant in everyday life.
