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

Integral is a branch of algebra included in the calculus course, making it essential to master. This research aims to analyze the skills of students with visual learning styles, auditory learning styles, and kinesthetic learning styles using discovery learning on the topic of integrals. The method used in this study is a mixed-method approach with an Explanatory Design. The first stage involves the collection and analysis of quantitative data, which takes priority in answering the research questions. The next stage is the qualitative data collection phase, where three students with different learning styles are interviewed to gain deeper insights. The results of the study indicate that learning using the discovery learning model has a significant effect on students' learning outcomes. The average score improvement of visual, auditory, and kinesthetic students shows positive results through learning using the discovery learning model, with the highest improvement seen in kinesthetic students (23.67) and visual students (22.89). The results of the mean comparison test or ANOVA (One-Way ANOVA) show that the significance value is 0.027 < 0.05, which means there is a difference in the mean posttest scores of visual, auditory, and kinesthetic students. This study demonstrates the significant impact of the discovery learning model on integral learning outcomes, revealing that visual learners outperform auditory learners, while kinesthetic learners show comparable outcomes to visual learners.

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 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

This study examines the evolving landscape of formative assessment in primary and secondary education through bibliometric analysis, emphasizing theoretical foundations, technological integration, and global applications. A total of 398 documents from the Scopus database (1997–2024) were analyzed using Biblioshiny for R, with an annual growth rate of 14.74%. Key metrics such as keyword co-occurrence, thematic clusters, and global collaboration networks were evaluated to identify prevailing research trends and gaps. The results highlight significant themes, including feedback mechanisms, self-assessment, peer assessment, and the integration of digital technologies like e-learning, gamification, and artificial intelligence. Collaboration patterns reveal the USA, China, and Germany as research hubs, while Southeast Asia demonstrates regional efforts. However, barriers such as inconsistent definitions, limited teacher training, and technological inequities persist. This study contributes novel insights by bridging critical gaps in the literature, particularly the lack of cultural perspectives and underexplored non-traditional educational contexts. It combines bibliometric analysis with thematic insights to illuminate the transformative potential of formative assessment across diverse educational settings. Educators and policymakers can use these findings to develop regionally tailored strategies for formative assessment, addressing implementation challenges and promoting effective practices globally. By fostering personalized learning and equitable access, formative assessment supports inclusive education, narrowing disparities across various learner demographics.

Abstract

The glyphosate’s continuous application in agricultural fields has caused adverse environmental effects. Utilizing indigenous microorganisms as glyphosate-degrading agents can be an effective and eco-friendly solution. Isolate Cf2, obtained from a local chili pepper plantation in Indonesia, grew as a co-dominant isolate in media with 50 ppm glyphosate, indicating its potential as glyphosate-degrading bacteria. However, this isolate cannot be applied yet because it has not been identified. Identification can provide initial insights into the safety of indigenous isolates for ecological application. Thus, this study aims to identify isolate Cf2 by utilizing the 16s rRNA gene sequence as the genetic marker. The data was compared to the database using the web-based BLAST2 program (version 2.13.0). Then, the evolutionary relationship of this isolate with its closest relatives was assessed through phylogenetic tree reconstruction. The results demonstrate that the isolate Cf2 has a sequence similarity of 98.88% with Bacillus subtilis. The phylogenetic tree reconstruction further indicates that isolate Cf2 forms a monophyletic clade with this species. Hence, it can be concluded that isolate Cf2 is indeed B. subtilis. This study is the first report of glyphosate-degrading B. subtilis isolated from chili pepper plantations in Indonesia, offering a new insight into bioremediation strategies.
