Abstract

Kaur Regency has abundant marine resources, particularly Octopus vulgaris. According to data from the local Fisheries Service, octopus production in 2023 reached 349,310 kg. However, utilization remains limited to dried products. An alternative innovation is processing octopus into flour, which offers high nutritional value, longer shelf life, and broader applications as a raw material for various food products. This study aimed to produce octopus flour and analyze its proximate composition. Fresh octopus samples were selected, cleaned, boiled, sliced, and sun-dried until completely dehydrated. The dried material was then ground into powder and stored in airtight containers. Proximate and mineral analyses were conducted at the Biology Laboratory, University of Bengkulu, following SNI 01-2715-1996 standards. The macronutrient analysis showed that fat content was 8.19%, meeting SNI Class II standards (<10%). Protein content reached 32.41%, while carbohydrate content was 7.08%. For micronutrients, calcium content was 0.15%, meeting SNI Class I standards (>0.1%), magnesium content was 0.87%, and iron content was 5,412 ppm. Additional nutritional analysis indicated moisture content of 1.96%, fiber content of 0.73%, and ash content of 4.2%, all complying with SNI Class I criteria. In conclusion, octopus flour produced from local resources meets SNI Class I and II standards for macronutrients, micronutrients, and other nutritional parameters, demonstrating its potential as a nutritious and durable alternative food ingredient.

Abstract

Understanding students’ mental models is essential to identify conceptual and representational challenges in learning intricate biological processes such as photosynthesis. This study explores senior high school students’ mental models of photosynthesis using a five-tier open-ended diagnostic test that integrates conceptual and visual understanding. A qualitative case study was conducted with 27 students in Bandung, Indonesia. The results revealed that only 22.8% of students demonstrated scientific understanding of the light reaction, and just 16.0% did so for the dark reaction. The majority of students exhibited initial or synthetic models, indicating fragmented knowledge, misconceptions, and difficulties in depicting key photosynthesis processes. Visualization results further highlighted students’ limited ability to construct accurate scientific representations, especially for the dark reaction. These findings suggest a need for model-based teaching strategies, multimodal representations, and formative assessments to enhance students’ conceptual and visual understanding of photosynthesis.

Abstract

The practicum guide is a guideline for conducting practicum activities. Cincalok was chosen as the practicum guide because of its closeness to the local wisdom of the students, so that the concept of conventional biotechnology can be understood contextually. The use of locally-based fermented products supports relevant learning, and strengthens students' appreciation of local culture and food resources. This study aims to analyze the feasibility of teaching materials for practical guides on conventional biotechnology sub-material regarding the results of physical, chemical, and organoleptic tests of cincalok in West Kalimantan. The research design used was quantitative descriptive. The feasibility test was conducted in three stages, namely instrument validation, media validation, and data analysis. The validators consisted of five people, namely two lecturers from the Biology Education Study Program and three biology teachers from grade X high school. The validation results obtained a CVR value of 0.99 and a CVI value of 0.99, indicating that all aspects of the practical guide assessment were valid. This shows that the practical guide that was created met the criteria in terms of format, language, and content. The practical guide that met the validity criteria could be used in the next stage to evaluate its effectiveness.

Abstract

This study aims to identify the types of spices used in Ancak cuisine, and to describe the composition and basic ingredients. The research methods included field surveys and in-depth interviews, which were analyzed using an ethnobotanical approach. The level of plant utilization was analyzed using Use Values (UVs), and the frequency of use based on cultural importance was measured using Index of Cultural Significance (ICS), while the frequency of mention of plant types was analyzed using Relative Frequency of Citation (RFC). The results show that there are 19 types of spice plants used in Ancak cuisine. The highest UVs value is found in Tamarindus indica with a value of 6, followed by Cinnamomum verum with a value of 5 and Myristica fragrans with a value of 2. The highest ICS values for spice plants are found in Allium cepa and Allium sativum at 30, and Zingiber officinale at 12. In addition, 20 types of plants were identified as ingredients and basic materials for making Ancak. The highest UVs value was found in Apium graveolens at 2, followed by Raphanus sativus var. hortensis and Nasturtium officinale at 1. The highest ICS value was found in Oryza sativa at 30, followed by Cocos nucifera at 9 and Allium fistulosum at 6. The highest RFC value was also found in Oryza sativa at 1, followed by Glycine max at 0.95, and Cucumis sativus at 0.35. These findings indicate that the Ancak dish reflects rich local ethnobotanical knowledge and strong social and cultural values.

Abstract

Creative thinking is an essential skill that must be explicitly and systematically taught in classrooms because of its significant contribution to student learning outcomes. However, many schools still rely on conventional teaching methods, which often lead to student boredom, reduced motivation, and low engagement. Therefore, an effective learning model is needed to address this issue. This study examines the effect of the Reading Map Group Investigation (Remap-GI) learning model on cognitive learning outcomes and creative thinking skills in Biodiversity material at SMAN 1 Muncar. This study employed a quantitative quasi-experimental approach using a non-equivalent control group design. The sample consisted of 70 students (36 in the experimental group and 34 in the control group) selected through random sampling. Creative thinking data were collected using open-ended test items based on four indicators, while cognitive learning outcomes were measured using pre-test and post-test scores. Data were analyzed using Analysis of Covariance (ANCOVA), preceded by normality and homogeneity tests. The results showed that the ANCOVA test for creative thinking skills produced a significance value of 0.000 (p < 0.05), indicating that the Remap-GI model significantly improved students’ creative thinking compared to the control group. Similarly, the ANCOVA test for cognitive learning outcomes also showed a significance value of 0.000 (p < 0.05), indicating a positive effect on students’ cognitive performance. Practically, this model can be an alternative teaching strategy to reduce boredom, increase active participation, and improve conceptual understanding, especially in agro-industrial school environments where students need support in developing independent learning habits.

Abstract

Critical thinking skills and sustainability awareness are essential competencies for addressing global challenges in the 21st century. However, students in Indonesia still demonstrate relatively low levels of both competencies. This study examines the effect of the Concept Attainment Model (CAM) based on Education for Sustainable Development (ESD) on the improvement of students’ critical thinking skills and sustainability awareness in ecosystem learning. A quasi-experimental design with a non-equivalent control group was employed, involving two tenth-grade classes at one public high school in East Lampung, Indonesia (experimental group, n = 28; control group, n = 29). Data were collected through pretests, posttests, and sustainability awareness questionnaires. Data were analyzed using normalized gain (N-gain), independent samples t-test, and effect size (Cohen’s d). Results showed that the experimental class achieved higher improvement in critical thinking skills than the control class, with moderate N-gain values (0.47 vs 0.37) and a large effect size (d = 1.12. Sustainability awareness improved more substantially in the experimental group than in the control group, with emotional awareness achieving a high N-gain (0.89 vs 0.52), behavioral and attitude awareness showing moderate improvement (0.61 vs 0.27), and sustainability practice awareness demonstrating lower but still higher gains in the experimental class (0.51 vs 0.31. These results indicate that the integration of CAM with ESD effectively enhances both cognitive and affective domains of learning. The study highlights the potential of this approach for fostering competencies that are critical to sustainable education and suggests its application across various subjects and educational levels.
