Abstract

Learning difficulties are one of the problems that students often experience in the biology learning process, especially in abstract and complex materials such as the human nervous system. Less than optimal understanding of concepts can have an impact on low student learning outcomes and hinder the achievement of learning goals. This study aims to analyze students' learning difficulties in understanding the concept of nervous system material in humans at MAS Hajijah Amalia Sari for the 2024 academic year. This study uses a quantitative approach with the support of qualitative data. The subject of the study was 25 students in grade XI of MAS Hajijah Amalia Sari. Data collection techniques are carried out through concept comprehension tests, interviews, and documentation. The concept comprehension test is prepared based on seven indicators of concept comprehension, namely interpreting, giving examples, grouping, summarizing, drawing inferences, comparing, and explaining. The data obtained was analyzed descriptively to determine the level of students' understanding of concepts and the form of learning difficulties experienced. The results showed that the level of students' conceptual understanding of nervous system material was in the medium category with an overall average score of 60. Indicators provide examples and interpret are in the good category, while indicators summarize, draw inferences, compare, and explain are in the sufficient category and indicate a more dominant level of difficulty. Students' learning difficulties are influenced by various internal factors, such as low high-level thinking skills, uneven learning motivation, and differences in students' initial abilities. In addition, external factors such as limited learning media, practicum facilities, and learning methods that are still dominated by lectures also affect students' understanding of concepts. Based on these findings, improvement efforts are needed through the application of more innovative learning methods, the use of visual and audiovisual media, and student-centered learning to improve conceptual understanding and reduce students' learning difficulties in human nervous system materials.

Abstract

Sustainable agriculture requires innovations in environmentally friendly organic fertilizers to maintain soil fertility and reduce dependence on inorganic fertilizers. One such innovation is Jakaba (Jamur Keberuntungan Abadi), a liquid organic fertilizer produced through the fermentation of organic materials involving microbial activity. This study aims to compare three methods of Jakaba production, namely the firewood method, gas stove method, and rice water method, in terms of fermentation success. This research was conducted on April 06 at the Biology Laboratory yard of STAIN Mandailing Natal using a simple experimental method through direct observation. The observed parameters included growth rate, mycelium thickness, Jakaba quality, production cost, material availability, and processing procedure. The results showed that the firewood method produced the most optimal Jakaba growth, reaching approximately ±11 cm in height with thick mycelium and the best quality, while the gas stove method did not produce any growth, and the rice water method resulted in slow growth of about ±3 cm after three weeks of fermentation. Therefore, the firewood method is considered the most effective method for Jakaba production.

Abstract

This research is motivated by the low level of student learning independence in the learning process, which is indicated by the lack of initiative, self-confidence, discipline, and responsibility of students in learning. In addition, the low awareness of students in utilizing digital media or technology also causes limited interaction between teachers and students. This shows that the use of digital learning media is not fully effective in increasing student learning independence, because students' self-awareness in managing time, responsibility, and motivation for independent learning still need to be improved. The purpose of this study was to determine the effectiveness of the use of digital learning media on student learning independence in the excretory system material. This type of research is a quasi-experimental design. The population of this study was all 72 students of class XI MIA 1 and 2, and the sample used was also 72 students of class XI MIA 1 and 2. The data collection technique used a learning independence questionnaire, which consisted of 25 pretest and posttest statements. The data obtained were then analyzed using the SPSS 22.0 application for windows. Based on the results of the Analysis of Covariance (ANCOVA) test, the effectiveness value obtained was 0.001 < 0.05. It can be concluded that digital learning media such as learning videos provide effectiveness towards the learning independence of grade XI high school students in biology subjects. This shows that the use of digital learning media such as learning videos has a positive effect and can improve students' independent learning abilities, increase initiative and creativity, and facilitate students to have a better understanding of the learning concepts taught.

Abstract

Competency-based learning evaluation is an important aspect of Biology instruction in secondary education, as it assesses not only students’ mastery of knowledge but also their skills and attitudes. However, various studies indicate that evaluation practices in Biology learning remain dominated by cognitive assessment, thereby limiting the optimal measurement of competencies in a comprehensive manner. This study aims to analyze competency-based Biology learning evaluation systems in secondary education using a Systematic Literature Review (SLR) approach. The research method followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Articles were retrieved from Google Scholar, SINTA, DOAJ, and Scopus databases, with publications limited to the period from 2021 to 2026. The selection process consisted of article identification, screening, eligibility assessment, and inclusion. Of the 120 articles identified, 15 met the inclusion criteria and were analyzed using content analysis techniques.The findings indicate that competency-based evaluation in Biology learning has developed through the implementation of authentic assessment, performance assessment, portfolios, higher-order thinking skills (HOTS) assessment, and the use of digital technology. The application of these evaluation approaches contributes to improving students’ critical thinking skills, scientific literacy, and problem-solving abilities. Nevertheless, several challenges remain, including the dominance of written tests, limited affective and psychomotor assessment instruments, and teachers’ limited competence in developing competency-based assessments. Therefore, strengthening teachers’ capacity and developing more comprehensive evaluation instruments are necessary to support competency-oriented Biology learning.

Abstract

Clean and Healthy Living Behavior (CHLB) is one of the key promotive and preventive approaches to improving public health. As a productive age group, university students play a significant role in fostering a healthy lifestyle culture both on campus and within the wider community. This study aimed to analyze the level of CHLB implementation among university students. A descriptive quantitative research design with a survey method was employed. The research instrument consisted of a CHLB questionnaire covering indicators of personal hygiene, nutritious food consumption, physical activity, rest patterns, environmental hygiene, utilization of health services, and smoke-free behavior. The data were analyzed using descriptive statistics, including percentages and mean scores. The findings revealed that the overall level of CHLB implementation among university students was categorized as high. Personal hygiene and environmental hygiene achieved the highest scores, whereas physical activity and rest patterns were only categorized as moderate. These findings indicate the need for sustainable health promotion programs to enhance students' awareness and encourage the consistent adoption of clean and healthy living behaviors.

Abstract

This study aims to evaluate the implementation of Biology learning assessment on the concept of environmental pollution in the Merdeka Curriculum for Grade VIII junior high school students. The evaluation was conducted on the implementation of diagnostic, formative, and summative assessments applied by the teacher during the learning process. This study employed an evaluative approach using Stake’s Countenance evaluation model, which includes the stages of antecedents, transactions, and outcomes. The research subjects consisted of one science teacher and 32 Grade VIII junior high school students. Data were collected through observation, document analysis, questionnaires, and interviews. The data were analyzed using descriptive quantitative and qualitative methods by comparing actual conditions with the assessment standards in the Merdeka Curriculum. The results showed that the implementation of Biology learning assessment on environmental pollution material was in the good category, with an average implementation rate of 83.2%. Diagnostic assessment obtained a score of 78.5%, formative assessment 85.6%, and summative assessment 85.4%. Nevertheless, challenges were still found in the implementation of non-cognitive diagnostic assessment and the provision of individual feedback to students. This study recommends the development of more authentic assessments that are oriented toward students’ learning needs in accordance with the principles of the Merdeka Curriculum.

Abstract

This study aims to evaluate the quality of Biology learning assessment instruments on the excretory system material for Grade VIII junior high school students based on their alignment with Learning Outcomes (Capaian Pembelajaran, CP), Learning Objectives (Tujuan Pembelajaran, TP), item indicators, cognitive domains, and item quality. This study employed an evaluative descriptive approach using a document evaluation model. The data were obtained through an analysis of 30 test items used by teachers in the excretory system material. The evaluation instrument was a review sheet covering aspects of substance, construction, language, alignment with CP and TP, and the distribution of cognitive levels based on the Revised Bloom’s Taxonomy. The results showed that most of the items were aligned with CP and TP; however, they were still dominated by lower cognitive domains (C1–C2). The alignment of the indicators reached 86.67%, whereas the proportion of HOTS items remained low. These findings indicate the need to develop assessment instruments that are more oriented toward higher-order thinking skills.

Abstract

Lichens are symbiotic organisms formed by the union of fungi and algae or cyanobacteria that play an important role in ecosystems, including as bioindicators of environmental quality, pioneers in soil formation, and producers of bioactive compounds. The Minanga Waterfall area, located in Rantau Balai Village, Aranio Subdistrict, Banjar Regency, has a humid, shaded environment with relatively low pollution levels, making it a potential habitat for various lichen species. This study aims to identify the lichen species found in the Minanga Waterfall area. The research was conducted using an exploratory survey method with purposive sampling and transect surveys along predetermined observation routes. Data were obtained through direct observation, documentation, morphological identification, and literature review to determine the species found. The results showed that 14 lichen species belonging to 14 families were identified, namely Phlyctis argena, Punctelia jeckeri, Dyplolabia afzelii, Rhizocarpon lecanorinum, Phellinidium ferrugineofuscum, Cylindrobasidium laeve, Leptogium cyanescens, Trapelia coarctata, Trypethelium virens, Bacidia viridifarinosa, Ceriporia purpurea, Peniophora limitata, Lepraria finkii, and Dictyonema sericeum. Most species were found on tree trunks, with crustose thalli being the dominant type. The results of this study can serve as a source of scientific information on lichens in the Minanga Waterfall area and support the utilization of local resources as a source of biology education.
