Abstract

Environmental Management Systems (EMS) have been widely implemented to improve organizational environmental performance; however, their integration with Green Supply Chain Management (GSCM) remains limited, particularly in the seafood processing industry. This study aims to evaluate the gap between operational-level EMS implementation and integrated GSCM practices at PT. IAMBEU Mina Utama while identifying priority improvement areas to strengthen sustainable supply chain performance. A quantitative-evaluative case study approach was employed using the Green Supply Chain Operations Reference (Green SCOR) framework covering the Plan, Source, Make, Deliver, and Return processes. Data were collected through Likert-scale questionnaires, interviews, field observations, and document analysis. Gap analysis and priority assessment based on environmental and operational impacts were applied to determine critical Key Performance Indicators (KPIs). The results show that EMS implementation (4.20) exceeds GSCM implementation (3.89), indicating a moderate integration gap. The largest gaps were identified in the Return, Deliver, and Plan processes, while priority KPIs include waste management monitoring, circular economy implementation, supplier environmental evaluation, transportation emission monitoring, energy efficiency, and production waste management. The findings indicate that although the company has established a strong internal environmental management system, sustainability practices have not been fully integrated across the supply chain. This study contributes to the development of EMS–GSCM integration using the Green SCOR framework and provides practical recommendations to support sustainable supply chain performance in line with the Sustainable Development Goals, particularly SDG 12 (Responsible Consumption and Production).

Abstract

Stunting is a nutritional problem that requires innovation in functional food products made from natural ingredients that are nutritious and easy to consume. This study aimed to formulate an anti-stunting nutraceutical product based on multigrain ingredients and moringa leaves (Moringa oleifera L.) in the form of a cereal-like health drink. Product evaluation was conducted through organoleptic testing, pH stability testing, proximate analysis, and hedonic testing. The organoleptic results showed that the three formulations had relatively similar color, taste, aroma, and texture characteristics and remained stable during one month of storage. The pH values were also stable, indicating good chemical stability of the product. Proximate analysis showed that the protein content of 8.14-9.13%, ash content of 1.36-1.74%, and carbohydrate content of 75.15-77.88% met the requirements of SNI 01-4270-1996. However, the moisture content of 7.56-8.01% still exceeded the maximum limit, while the fat content of 4.49-6.19% remained below the standard. The hedonic test results showed that all formulations were accepted and preferred by the panelists, with an average score exceeding 4. Formulation 3 showed superiority in the color parameter, while Formulation 2 was more preferred in terms of taste. Overall, this product has the potential to be developed as an anti-stunting nutraceutical innovation. However, further optimization of the drying process and the composition of fat-source ingredients is still required.

Abstract

Rainfed paddy fields relying entirely on rainfall are vulnerable to seasonal water deficits and limited to one planting season per year (Cropping Index/CI 100). This study analyzed the water balance of 77 ha of rainfed paddy land in Padang Kunik Village, Kuantan Singingi Regency, and formulated a technical storage solution to improve irrigation water availability. Water availability was calculated using the Simple Water Balance method with 20 years of rainfall data (2006–2025) from three rain gauges, while irrigation demand followed KP-01 guidelines. The Ripple (mass-curve) method determined the required Effective Storage Capacity. Results showed deficits in seven separate periods, with a cumulative peak deficit of 140,647.00 m³ in April I and a total required storage volume, after accounting for evaporation, seepage, and sediment losses, of 175,077.41 m³. A combination of an embung (172,800.00 m³ on 4.3 ha of non-productive land) and 4,562 m of long storage was planned, yielding a total volume of 177,362.00 m³, or 101% of the requirement, distributable to the paddy fields by gravity given the elevation difference. The proposed system is technically feasible to eliminate seasonal deficits and could raise the Cropping Index from CI 100 to CI 200.

Abstract

The absence of quality standards for moringa leaf powder has caused product variability, limiting consistency, competitiveness, and industrial use. This study developed quality criteria using the FACTS framework, integrating stakeholder priorities (via Exponential Comparison Method across 24 participants) with laboratory characterization of samples from five Indonesian regions. Stakeholders prioritized food safety, sensory quality, and nutritional consistency. However, food safety parameters were excluded as they are already regulated by Indonesian Food and Drug Authority (BPOM). Laboratory data revealed high variability in fineness (CV = 28.83%) and acid-insoluble ash (CV = 52.67%). Benchmarking against Kenya Standard KS 2848:2019 confirmed compliance for moisture and acid-insoluble ash, while fineness, ash, protein, and color required local specifications. Using Adopt–Adapt–Originate, acid insoluble ash was adopted (≤ 0.5%); moisture and fineness adapted; and ash, protein, and color originated. Stakeholder expectations (protein ≥ 27%; moisture ≤ 8%) exceeded empirical thresholds (≥ 23%; ≤ 10%), resolved through inclusive limits supporting a future tiered system. Proposed specifications, i.e. color (green to bright green), moisture (≤ 10%), ash (≤ 13%), acid-insoluble ash (≤ 0.5%), protein (≥ 23%), and fineness (≥ 80% passing 100-mesh) provide a scientific foundation for moringa powder standard in national level.

Abstract

This study aimed to examine the effectiveness of the PAREPIA teaching aid in enhancing fifth-grade students' conceptual understanding of the human respiratory system. A quantitative approach employing a quasi-experimental nonequivalent control group design was conducted with 64 fifth-grade students, comprising 32 students in the experimental class and 32 students in the control class. Data were collected using a 25-item multiple-choice test administered as a pretest and posttest. The data were analyzed using the Rasch Model with stacking analysis through Winsteps 4.8.2 to evaluate changes in students' conceptual understanding. The results showed that the experimental class achieved greater conceptual gains than the control class. The mean measure increased from 0.28 to 1.70 logits (+1.42 logits) in the experimental class, whereas the control class increased from 0.24 to 1.19 logits (+0.95 logits). These findings indicate that the PAREPIA teaching aid effectively facilitates students' conceptual understanding by providing interactive, hands-on learning experiences that help transform abstract concepts into concrete understanding. Therefore, the PAREPIA teaching aid is effective in improving fifth-grade students' conceptual understanding of the human respiratory system and contributes to enhancing the quality of elementary science education.

Abstract

This study aims to analyze the influence  of Mind Mapping learning strategies  on the creativity and sustainability awareness of elementary school students in motion energy learning. This study uses a quantitative approach with a quasi-experimental research method with a nonequivalent control group design. The research subjects consisted of elementary school students who were divided into experimental groups with the application of Mind Mapping strategies  and control groups with conventional learning. The research data was collected through creativity test instruments, sustainability awareness questionnaires, and observation of learning activities, then analyzed using inferential statistical tests. The results of the study show that the application of the Mind Mapping strategy has a positive influence on increasing students' creativity and sustainability awareness in motion energy materials. Students who participate in Mind Mapping-based learning  show better ability to organize concepts, develop ideas, and understand the relationship between energy use and environmental sustainability. These findings suggest that the Mind Mapping strategy can be an innovative learning alternative that supports the development of creative thinking skills and sustainability literacy in primary schools. Thus, the Mind Mapping strategy contributes to creating science learning that is more meaningful, contextual, and oriented towards 21st century competency development.

Abstract

This study aimed to compare the learning outcomes of fifth-grade students in Natural and Social Sciences (IPAS) taught using the Somatic, Auditory, Visual, Intellectual (SAVI) learning model and the Visual, Auditory, Kinesthetic (VAK) learning model. This study employed a quantitative approach with a quasi-experimental posttest-only design involving 64 fifth-grade students. The participants consisted of 32 students in the SAVI group and 32 students in the VAK group. Data were collected using a 25-item multiple-choice post-test and analyzed using the Rasch Model with the stacking technique using Winsteps version 4.8.2. The results showed that the mean measure of the SAVI group was 1.49 logits, whereas the VAK group achieved 1.67 logits, indicating a difference of 0.18 logits. Both learning models supported students' IPAS learning outcomes, with the VAK learning model demonstrating a higher mean measure than the SAVI learning model. These findings indicate that the VAK learning model is a promising alternative for supporting student-centered IPAS learning in elementary schools.

Abstract

Developing an effective game-based learning environment to improve elementary students' critical thinking skills remains a challenge in science education, particularly for food chain learning. This study aimed to develop and evaluate an Interactive Articulate Storyline-based Food Chain Edugame using a Research and Development (R&D) approach with the ADDIE model. Product quality was evaluated through expert validation, teacher and student practicality assessments, instrument testing, and effectiveness analysis using a quasi-experimental pretest–posttest control group design. The critical thinking instrument consisted of 12 essay items, of which 10 were valid and demonstrated high reliability (Cronbach's Alpha = 0.877). The developed learning environment met the criteria for validity, practicality, and effectiveness. No significant difference was found between the experimental and control groups in the pretest (p = 0.725), whereas the posttest showed a significant difference (p < 0.001). The experimental group achieved a higher mean posttest score (85.63) and normalized gain (0.680) than the control group (67.34; 0.273). These findings demonstrate that integrating game-based learning activities, formative assessment, and immediate feedback within a meaningful learning design effectively enhances elementary students' critical thinking skills.

Abstract

Food security remains a major challenge in developing countries, particularly in relation to the vulnerability of food consumption among low-income households. Rice plays a central role in Indonesia’s food system as the main staple food and a key determinant of food availability and access. However, increasing rice production does not necessarily guarantee adequate food consumption if economic access to food remains limited. This study aims to analyze the relationship between rice production, food access factors, and the prevalence of food consumption inadequacy as an indicator of food poverty vulnerability. The analysis employs a Two-Stage Least Squares (2SLS) econometric approach using secondary data from the Indonesian Central Bureau of Statistics and related institutions for the period 2018–2023. The first-stage estimation shows that paddy harvested area is the most significant factor influencing rice production, highlighting the importance of land utilization in determining food availability. In the second stage, the number of poor population emerges as the most influential factor affecting food consumption inadequacy, while income per capita and average rice production contribute to reducing the prevalence of inadequate food consumption. These findings indicate that food insecurity is driven not only by the availability of staple food but also by households’ economic ability to access food. Therefore, strengthening food security requires integrated policies that simultaneously support agricultural production, protect agricultural land, and reduce poverty to improve household access to food

Abstract

This study aimed to determine the genetic diversity, heritability, and correlation of quantitative traits of the fifth generation (S5) of selfing lines of maize plants. The experiment was conducted in the dry land of Gumantar village, North Lombok, from February to May 2025. The design used in this experiment was a randomized block design. The number of treatments was 30 S5 lines. Each treatment was repeatedThe experiment was conducted twice, resulting in 60 experimental units. Eleven quantitative characters were observed, consisting of growth variables, yield components, harvest age, and yield. The experimental data were analyzed using analysis of variance at a significance level of five percent. The correlation between characters and yield was calculated using Pearson rank correlation. The results showed that six quantitative characters of the S5 line had narrow genetic diversity and six characters had moderate criteria; with genetic diversity coefficients ranging from 1.56 for harvest age and 13.02 for yield. The broad-sense heritability of 1,000-grain weight was high, six characters were moderate, and the rest were narrow. The yield character was strongly correlated with the harvested dry cob weight per plant; with cob length being moderately correlated; four characters were weakly correlated, and the other characters were not correlated with yield. The plants selected to form the sixth selfing generation were taller plants with narrower leaf angles and flowering simultaneously
