Abstract

Feed represents the largest expense in catfish (Clarias sp.) aquaculture, accounting for up to 70% of production costs. Improving feed efficiency is therefore essential to enhance productivity and reduce operational costs. This study developed and evaluated an Internet of Things (IoT)-based automatic feeder designed for small-scale aquaculture. The novelty of this research lies in the integration of Arduino and BARDI components into an affordable autofeeder system that supports precision feeding management for smallholders. Two feeding methods were compared: manual feeding and automatic feeding using the developed IoT-based system. Productivity indicators measured included Feed Conversion Ratio (FCR), Specific Growth Rate (SGR), Survival Rate (SR), and water quality. Results showed that conventional feeding produced lower FCR (0.29) and higher SGR (18.50%/day) during the early growth phase. Survival rates were relatively low (60–63%) but improved in later weeks. Most water quality parameters remained within the optimal range, except for temperature, which slightly exceeded tolerance levels and contributed to mortality. Although the IoT-based feeder requires further refinement to match manual feeding performance, it demonstrates strong potential to improve feeding accuracy, reduce labor dependency, and promote sustainability in small-scale catfish aquaculture.

Abstract

21st-century education demands that students not only master content but also possess scientific communication skills, thereby requiring innovative learning approaches to develop these competencies. The STEM approach, which integrates science, technology, engineering, and mathematics, along with the RANDAI learning model culturally-based and problem-solving oriented is considered effective in fostering such skills. This development research employed the Plomp model, consisting of three phases: preliminary research, prototyping, and assessment. The object of the study was a RANDAI Teaching Module integrated with STEM, with Grade VIII students as the subjects. The instruments used included tools for assessing validity, practicality, and effectiveness to measure students’ scientific communication and argumentation skills. Data analysis for validity and practicality employed descriptive analysis, while effectiveness was analyzed using ANOVA tests with SPSS software. The results showed that the module is valid with a score of 87.33%, highly practical with scores of 92.44% from teachers and 91.24% from students, and effective in enchance students' scientific communication skills

Abstract

Despite the central role of teachers in fostering students’ scientific literacy, assessment instruments targeting in-service science teachers remain limited. This study aimed to develop and examine the preliminary quality of a scientific literacy instrument for junior high school science teachers, informed by OECD documents outlining the direction of the PISA 2025. A design-based research approach was employed using Tessmer’s formative evaluation model, encompassing iterative stages of preliminary analysis to pilot field test. The instrument comprised nine context-rich stimuli and 25 items across multiple formats designed to elicit scientific reasoning and decision-making in real-world contexts. Expert validation produced a Mean Expert Score of 4.67, while teacher readability evaluation yielded a Mean Readability Score of 4.29, indicating strong content representation and clarity. Pilot psychometric analysis showed a balanced distribution of item difficulty (32% easy, 40% moderate, and 28% difficult), and item-level validity and discrimination indices provided diagnostic evidence for refinement. Pilot psychometric analysis indicated that the instrument’s reliability remains preliminary and highlights the need for further refinement through larger-scale field testing. Overall, this study contributes a forward-looking assessment instrument that supports formative evaluation of teachers’ scientific literacy and provides a robust foundation for subsequent large-scale validation aligned with emerging international assessment orientations.

Abstract

Arabica coffee seedlings grown on Ultisols often experience limited growth due to low levels of organic matter and nutrient deficiencies, presenting a major challenge for nursery productivity in Central Sulawesi. This study aimed to evaluate the effectiveness of organic matter derived from Paitan (Tithonia diversifolia) in improving the growth performance of Coffea arabica seedlings. A Completely Randomized Design (CRD) was employed using five compost dosages (0, 5, 10, 15, and 20 tons/ha equivalent) with four replications. Growth parameters—including germination time, plant height, stem girth, leaf number, leaf area, biomass accumulation, and relative growth rate—were observed over 17 weeks. Soil chemical properties were analyzed to assess changes in fertility. Data were processed using ANOVA followed by an HSD test at the 5% significance level. The results showed that compost substantially improved plant height, stem diameter, leaf number, shoot and root dry weight, and relative growth rate, while germination time, leaf area, and root length remained unaffected. Soil analysis indicated increases in organic carbon, nitrogen, potassium, and cation exchange capacity, demonstrating enhanced nutrient availability. The study concludes that Paitan compost, particularly at 13–15 g per polybag, is an effective organic amendment that improves seedling vigor and offers a sustainable alternative to chemical fertilizers for nursery management on Ultisols.

Abstract

This study addresses the need for culturally responsive science learning in elementary teacher education by developing and empirically examining Affiliation–Interpersonal Skills (AKI), comprising affiliation motivation and interpersonal skills, within an ethnoscience learning context. Using a cross-sectional design, the study involved 50 prospective elementary teachers from a public university in Papua, Indonesia, most of whom were from disadvantaged, frontier, and outermost areas. Content validity was evaluated by five experts using the Content Validity Index, while item performance and internal consistency were examined through descriptive statistics, corrected item–total correlations, and reliability analysis. The results showed that the AKI instrument demonstrated strong content validity (most items I-CVI ≥ 0.78; S-CVI/Ave ≥ 0.90) and satisfactory reliability (subscale and total coefficients ≥ 0.70). Empirically, participants exhibited generally moderate to high affiliation motivation, reflecting a strong tendency toward collaboration and social connectedness, while interpersonal skills varied across individuals, particularly in empathic communication and conflict management. Based on these patterns, three AKI profiles were identified, indicating differentiated training needs in ethnoscience-based science learning. These findings suggest that AKI is a measurable and meaningful construct for mapping prospective teachers’ social–interpersonal readiness and for informing targeted interventions to strengthen culturally responsive science instruction.

Abstract

This study aims to develop a geography literacy-based learning model in an effort to build spatial intelligence in junior high school students. The model was developed using the ADDIE (Analysis, Design, Development, Implementation, Evaluation) procedure. The analysis stage found that teachers and students needed an innovative model that could connect geographical concepts with the surrounding environment. The design stage produced model tools in the form of syntax, lesson plans, student worksheets, and assessment instruments that were validated by experts with an average score of 88% (highly valid category). In the development stage, a limited trial involving 25 students showed an increase in student engagement from 62% to 82%. The implementation stage involved experiments in two classes, where the experimental class used the geographic literacy model and the control class used conventional methods. The posttest results showed that the average spatial intelligence of students in the experimental class reached 82.6 (high category), higher than the control class at 74.1 (medium category), with a significant difference (p < 0.05). The evaluation showed a 16% increase in geographic literacy skills and an 18% increase in spatial intelligence, as well as positive responses from teachers regarding the practicality of the model. These results confirm that the geography literacy-based learning model is valid, practical, and effective in improving the spatial intelligence of junior high school students.

Abstract

Fantasy hair styling in vocational cosmetology is commonly treated as a tacit craft activity, leaving limited evidence that material and geometry choices lead to ergonomic and stable designs. This study aimed to develop and validate craft-based support frames for fantasy buns while making materials-science and basic biomechanics concepts explicit. Using a 4D Research and Development model (Define–Design–Develop–Disseminate), undergraduate cosmetology students produced three frame variants (foam, thin wire, and polymer mesh). Product quality was evaluated by three cosmetology/beauty-education experts using a 1–5 Likert rubric covering aesthetics (neatness, proportion, creativity, harmony) and ergonomics (comfort, lightweight, ease of application/removal, positional stability). Three models conducted short wear-and-movement trials (standing, walking, head turns). Quantitative scores were converted to percentages and categorized; expert comments were analyzed thematically. Aesthetic performance averaged 87% (Very Good: neatness 90%, proportion 85%, creativity 88%, harmony 85%). Ergonomic performance averaged 83% (Very Good: comfort 85%, lightweight 82%, ease 80% [Good], stability 85%), with frame weights ranging from ~500 to 2,000 g. These results indicate that craft-based frames can produce visually coherent and ergonomically acceptable fantasy buns while supporting concept-based reasoning; future work should strengthen durability and application techniques and extend trials to longer wear durations.

Abstract

This study aimed to develop an electronic student worksheet (e-LKM) based on the case study method for the Multicultural Education course, focusing on multicultural education issues in Indonesia. The study was conducted due to students’ difficulties in understanding the material caused by limited interactive and accessible learning resources. This research employed a Research and Development (R&D) method using the 4D development model, consisting of define, design, develop, and disseminate stages. The developed e-LKM includes instructional materials, contextual case studies, videos, supporting articles, and higher-order thinking skills (HOTS) questions at the C4 and C5 levels. Canva and Flip PDF Professional were used to support interactivity and visual appeal. The feasibility of the e-LKM was evaluated through validation by subject-matter experts and media experts, assessments by the course lecturer, and student responses. The validation results indicated that the case study–based e-LKM was categorized as highly feasible in terms of content quality, language, visual design, and interactivity. Student responses also showed positive perceptions of accessibility, visual attractiveness, and the effectiveness of the e-LKM in enhancing understanding and learning engagement. Therefore, the case study–based e-LKM is suitable for use as an alternative learning resource in Multicultural Education.

Abstract

Mangrove ecosystems contribute to biodiversity conservation and climate-change mitigation through carbon storage. This study assessed the association between biodiversity (flora and fauna) and carbon stocks in mangroves of North Sulawesi across three management contexts: a conservation zone (Bunaken), a protected forest (Sondaken), and an unprotected area (Bitung). Field surveys were conducted to compile species inventories, and carbon stocks were estimated from biomass measurements. Protected sites showed higher species richness and larger carbon stocks than the unprotected site. Species richness was positively and significantly correlated with carbon storage, indicating that sites with greater biodiversity also tended to store more carbon. These results support the role of effective protection in maintaining both ecological integrity and carbon sequestration capacity. In conclusion, strengthening mangrove protection in North Sulawesi is likely to deliver co-benefits for biodiversity conservation and climate mitigation.
