Analysis of the growth and yield of Microgreens of the Brassica sp. family on the effect of limitied irradiation
Full text linkMicrogreens are a key concept in urban farming due to their ability to be grown easily, affordably, and efficiently in limited urban space. This study aims to determine the growth and yield of microgreens from the Brassica sp. family, which is cultivated under limited lighting conditions. This research was conducted from February to March 2025 at the laboratory of the Faculty of Agriculture, Singaperbangsa University, Karawang. This study employed an experimental method using a Split-Plot design within a Group Randomized Design framework, consisting of a main plot and a subplot. The main consisted of six levels of limited light exposure: indoor control, outdoor control, lighting at 60%, lighting at 50%, lighting at 40%, and lighting at 30%. The subplots were divided into three plant types: cauliflower, radish, and broccoli. Each treatment was repeated twice, resulting in a total of 36 experimental units. The effects of the treatment were analyzed using a variety of F-tests at the 5% significance level. When a significant interaction was detected, further analysis was conducted using the DMRT (Duncan's Multiple Range Test). The experimental results indicated a significant interaction between limited light exposure and plant type on the observed parameters of growth uniformity and plant height at 7 days after planting (DAP). The combination of lighting at 50% with broccoli plants provides the highest growth coherence value of 88%. In contrast, the highest value at 7 days after planting, measuring 6.55 cm, was observed in the lighting at 30% combined with broccoli plants
Analysis of students' ecoliteracy at Adiwiyata school in Padang City
Full text linkThe implementation of the Adiwiyata program is expected to enhance students' awareness and understanding of environmental issues, fostering a strong sense of ecoliteracy. However, based on the facts in the field, the existence of the Adiwiyata program has not been able to guarantee an increase in environmental awareness among students. This study aims to analyze the implementation of the Adiwiyata program in fostering and developing student ecoliteracy. This study is a descriptive research employing quantitative methods, aimed at objectively describing and analyzing existing phenomena or conditions related to the implementation of the Adiwiyata program and its impact on student ecoliteracy. In collecting data, researchers used a questionnaire completed directly by junior high school students participating in the Adiwiyata program, involving 101 students from six schools. The data collected from respondents were analyzed using quantitative descriptive analysis techniques. This study shows that students in Adiwiyata schools show a level of ecoliteracy in the sufficient category. This is due to various factors, one of which is that the implementation of the Adiwiyata program in junior high schools in Padang City is still relatively voluntary and independent. Support from all stakeholders, including the education office and local communities, is necessary to ensure that the Adiwiyata program is not only symbolic but also truly creates a sustainable ecoliteracy transformation.
 
Development of a critical thinking skills assessment instrument for students on diffusion and osmosis subject
Full text linkCritical thinking is a crucial 21st-century skill that enables students to analyze information, evaluate arguments, and make logical decisions. However, assessments in Biology education often focus more on factual knowledge rather than higher-order thinking skills. This research aimed to develop an assessment instrument for measuring students' critical thinking skills in diffusion and osmosis. This study used the ADDIE model, which consists of five stages: analysis, design, development, implementation, and evaluation. The research was conducted with 46 students from the XI MIPA class at MA Nurul Huda Munjul. The assessment instrument consists of multiple-choice questions designed to evaluate six components of critical thinking: interpretation, analysis, evaluation, inference, explanation, and self-regulation. Validation results indicate that 20 out of 24 test items are valid, while four require revision or replacement. Reliability testing using the split-half method shows a coefficient of 0.672, which falls into the moderate reliability category and is still acceptable for educational assessment purposes. The developed instrument provides teachers with a tool to evaluate students’ critical thinking skills better and tailor their teaching strategies accordingly. This study contributes to improving Biology education by promoting a more contextual and problem-solving-based approach to assessment
Development of test instruments to assess High School Students' critical thinking on the digestive system
Full text linkCritical thinking is one of the vital 21st-century skills, but many Indonesian students still show low proficiency in this area. To address this gap, it is essential to develop valid and reliable assessment instruments, particularly in science subjects like biology. This study aimed to develop and validate a test instrument to measure high school students' critical thinking skills on the topic of the digestive system. The research followed the ADDIE development model (Analyze, Design, Develop, Implement, Evaluate) and involved 74 eleventh-grade students. The instrument consisted of 30 multiple-choice items based on six critical thinking indicators by Facione: interpretation, analysis, evaluation, inference, explanation, and self-regulation. Validity and reliability were analyzed using the Rasch model with QUEST software. All items were found to be valid and fit the Rasch model, indicating strong construct validity. The item reliability was categorized as excellent (0.93), while student answer consistency was low (0.59), suggesting limited accuracy or care in responses. Most items (70%) were of moderate difficulty. The students' average critical thinking score was 47.25%, with self-regulation being the strongest indicator (63.51%) and analysis and inference being the weakest (35.13% and 38.64%). These results indicate that, although the instrument is effective in measuring critical thinking, students still encounter challenges, particularly in analytical reasoning. Enhancing learning strategies and assessment tools is crucial for improving students’ cognitive development in science education
Development of Socio-Scientific Issues Based Reproduction E-Module to Enhance Critical Thinking Skills
