Abstract

This study analyzed high school students’ needs regarding the integration of Minangkabau ethnoecology into biology education to support sustainability-oriented learning. Using a mixed-method design, quantitative data were obtained from a validated 20-item Likert-scale questionnaire and qualitative insights were obtained from open-ended questions. The sample involved 666 students from 14 senior high schools in West Sumatra, representing diverse ecological and cultural settings. Statistical analyses—including reliability testing (α = 0.807), normality, homogeneity, and one-way ANOVA—confirmed data consistency and revealed no significant differences among schools (p = 0.085), indicating homogeneous perceptions. Descriptive findings showed high mean scores in learning preferences (M = 4.23), material needs (M = 4.35), and expectations (M = 4.12), reflecting strong demand for contextual and culture-based biology learning. Qualitative responses supported these results, revealing that students linked conservation with traditional practices such as gotong royong, rimbo larangan, and lubuk larangan. These findings highlight the need to design ethnoecology-based biology modules aligned with SDG 4 (Quality Education) and SDG 15 (Life on Land), ensuring culturally grounded and ecologically meaningful science learning.

Abstract

This study aims to analyze the cost and revenue structure and evaluate the financial feasibility of the tilapia (Oreochromis niloticus) seed production (hatchery) business. The breeding stage is a crucial early phase in the aquaculture production cycle. The feasibility evaluation encompassed calculations of the Revenue to Cost Ratio (R/C), Break-Even Point (BEP), and Return on Investment (ROI). The method employed was a profitability analysis using revenue theory, applying the R/C, BEP, and ROI formulas to the business's cost and revenue data. The results indicate that from a technical and technological perspective, all operational requirements for the hatchery were met, including location suitability, operational scale, pond management, and resource utilization, supported by a single-level distribution system. Economically, the business showed profitability and business viability. The total revenue reached IDR 79,552,083. The financial analysis yielded an R/C ratio of 1.5, signifying that every Rp1 spent generated IDR 1.5 in revenue. The production break-even point (BEP) was achieved at 12,635,416 fish seeds. It is concluded that the tilapia seed production business is comprehensively feasible and profitable for further development.

Abstract

The global demand for table grapes continues to rise, driven by consumer preference for sweet, high-quality, and seedless fruit. Local varieties such as Bali grape (Vitis vinifera L. var. Alphonso Lavallee) remain less competitive than imported grapes due to small berry size, high acidity, and seed presence. This study evaluated the optimal concentrations of gibberellic acid (GA3) and potassium chloride (KCl) and their interaction effects on Bali grape fruit quality. The experiment used a factorial randomized complete block design with two factors: GA3 at 0, 50, 100, and 150 ppm, and KCl at 0 and 300 g per plant, with five replications. The results showed that GA3 significantly affected all observed parameters. Application of GA3 at 150 ppm produced the longest clusters, largest berry diameter, highest berry weight, and greatest sugar content, while simultaneously reducing seed number and seed weight, indicating induced parthenocarpy. KCl application significantly increased sugar content and berry diameter but did not influence seed characteristics. A significant interaction between GA3 150 ppm and KCl 300 g per plant was observed, resulting in the highest number of berries per cluster and the highest sugar concentration. Combined GA3 and KCl application improved fruit quality and enhanced Bali grape competitiveness

Abstract

This study examines the effectiveness of Project-Based Learning (PBL) in the development of a non-invasive hemoglobin detection system using photoplethysmography (PPG) integrated with artificial intelligence. A quasi-experimental design was applied to 26 Electrical Engineering students enrolled in Big Data Analysis, Sensor Design, and Embedded Systems courses. Students worked in groups to design, implement, and test prototypes. Data were collected through project rubrics, questionnaires, observations, and reflections, and were analyzed to determine the effectiveness index. The results revealed an overall effectiveness index of 3.8, categorized as good. The highest score was achieved in the affective aspect (4.2), reflecting strong motivation, proactive attitudes, and teamwork. Cognitive (3.9) and reflection (3.8) aspects also showed positive outcomes, while psychomotor (3.6) and product quality (3.5) remained weaker due to technical issues, including prototype accuracy and troubleshooting difficulties. The study demonstrates that PBL effectively integrates theory and practice, enhances 21st-century skills, and fosters meaningful learning experiences. Additionally, the findings highlight the potential of incorporating advanced technologies into engineering education while contributing to innovative health technology solutions for addressing malnutrition.

Abstract

Chili pepper (Capsicum frutescens L.) is a high-value horticultural commodity, but its productivity is often hampered by the excessive use of chemical fertilizers. This study aims to evaluate the effect of planting medium composition and plant growth-promoting rhizobacteria (PGPR) concentration on the growth and yield of chili pepper. The study was conducted from May to August 2025 at the Kedungrejo Seed Garden, Madiun Regency, using a factorial Randomized Block Design (RAK) with two factors: planting medium (soil, soil + compost, soil + manure, and soil + compost + manure) and PGPR concentration (0, 8, 16, and 24 ml/L), each replicated three times. Significant interactions were found between planting medium and PGPR on plant height, number of leaves, and fruit weight. The combination of soil + manure with PGPR at doses of 8 and 16 ml/L produced the highest values ​​for fruit weight (up to 2.99 g) and number of leaves (44). Soil and manure alone also increased root weight and fruit number while accelerating flowering. PGPR at a dose of 16 ml/L significantly increased shoot dry weight and shortened the harvest period. This study demonstrates that combining organic media with PGPR can sustainably increase chili productivity.

Abstract

Learning in Stereochemistry still tends to lack contextualization and the integration of technology and ethnosciences. This study aims to develop and evaluate Smart Ethno-STEM (System of Mobile Augmented Reality Technology) as an innovative learning medium in organic chemistry, particularly on stereochemistry topics, to enhance students’ metacognitive skills and scientific literacy. The research employed a Research and Development (R&D) design using the ADDIE model, involving validation, practicality, and effectiveness testing. The data were analyzed using descriptive validation and practicality scores, N-Gain, and MANOVA analysis. Validation results from one media expert and two material experts indicated that the media was categorized as highly valid (average score 4.46). Practicality tests conducted with 16 students showed a very practical use (average score of 4.75). The effectiveness test showed significant improvements in both metacognitive skills and scientific literacy, with N-Gain scores in the high category in the experimental group (metacognition 0.75; literacy 0.72) and in the medium category in the control group (metacognition 0.59; literacy 0.57). MANOVA results confirmed a significant influence of the class factor on both variables simultaneously (Sig. Hotelling’s Trace = 0.013). These findings demonstrate that Smart Ethno-STEM effectively enhances students’ higher-order thinking skills and connects scientific concepts with socio-cultural contexts, offering a contextual and technology-based solution for organic chemistry learning
