Abstract

Student participation and achievement in geography learning are often low due to limited use of contextual learning approaches. This study aimed to improve students learning activity and academic performance in Geography among tenth-grade students at Senior High School 1 Kampar through the REACT (Relating, Experiencing, Applying, Cooperating, Transferring) learning model. The study employed a classroom action research design conducted in three cycles, each consisting of planning, implementation, observation, and reflection. The participants were 38 students in the 2024/2025 academic year. Data were collected through observation sheets and achievement tests and analyzed descriptively with a paired sample t-test. The findings showed that student activity scores increased from 64.2 in Cycle I to 88.4 in Cycle III, and learning outcomes improved from 67.5 to 89.6, with significant differences across cycles (p < 0.05). These results demonstrate that the REACT model effectively enhances students’ engagement and academic performance. The implication of this study is that the REACT model can serve as an effective pedagogical strategy to promote active, contextual, and meaningful learning in geography education and other related disciplines

Abstract

This study aims to analyze the implementation of educational service practices that support children’s literacy and numeracy during the transition from Early Childhood Education (ECE) to Primary School, as well as to identify the supporting and inhibiting factors influencing this process. A descriptive qualitative approach was employed through classroom observations, in-depth interviews, and document analysis in schools implementing the Joyful Transition from ECE to Primary School program. The collected data were analyzed using the Miles, Huberman, and Saldaña interactive model. The results revealed three main themes. First, effective transition practices are supported by strong collaboration between ECE and primary school teachers, principal leadership, and active parental engagement. Second, play-based and science-integrated learning strategies enhance children’s literacy, numeracy, and socio-emotional development through contextual and exploratory learning experiences. Third, several challenges were identified, including limited learning resources, inconsistent perceptions of children’s academic readiness, and insufficient professional training related to transition policies. The discussion indicates that these challenges can be mitigated through reflective dialogue, peer mentoring, and the use of locally available learning materials. In conclusion, sustainable and joyful transition services require continuous teacher capacity building, pedagogical alignment between educational levels, and consistent policy support to ensure inclusive, meaningful, and developmentally appropriate learning experiences for all children.

Abstract

Goroho bananas (Musa acuminata L.) and gedi leaves (Abelmoschus manihot L.) have potential as functional foods due to their antioxidant content and nutritional properties. However, the use of these two ingredients in the form of composite flour and the determination of the optimal formulation to produce high antioxidant activity while maintaining acceptable physicochemical characteristics are still limited. This study aims to determine the optimal formulation of gedi leaf and goroho banana composite flour based on antioxidant activity and physicochemical properties. The study used a completely randomized design (CRD) with three replicates, consisting of five treatments, namely single gedi leaf flour, gedi leaf:goroho banana ratios of 75:25, 50:50, and 25:75, and single goroho banana flour. Antioxidant activity was analyzed by measuring total phenolic compound (TPC) content and DPPH free radical scavenging ability, while physicochemical characteristics included moisture, ash, fat, protein, carbohydrate, and crude fiber content. The results showed that increasing the proportion of gedi leaf flour significantly increased the protein, fat, ash, fiber, total phenolic content, and antioxidant activity, while increasing the proportion of goroho banana flour increased the carbohydrate content. These findings indicate a compromise between antioxidant capacity and energy contribution in composite flour formulations. Based on the balance between antioxidant activity and nutritional composition, the 50:50 and 75:25 gedi leaf:goroho banana formulations were determined to be the optimal formulations. The results of this study indicate that both formulations have the potential as functional composite flours for the development of antioxidant-rich food products

Abstract

This study evaluates the potential of molasses (sugarcane molasses) as the main feedstock for bioethanol production with a capacity of 100 kiloliters per day at PT Enaro Mojokerto. Assuming a fermentation efficiency of 90% and a theoretical sugar-to-ethanol conversion ratio of 0.511 kg ethanol per kg sugar, the required sugar is approximately 171.559 kg/day, corresponding to 343 tons of molasses (with 50% sugar content) to produce 100 KL of ethanol per day. Literature review and secondary data collection were conducted to evaluate three main criteria: feedstock availability, supply continuity, and fermentable sugar content. The analysis results indicate that East Java has a molasses production potential of 660,000 tons/year from 15 active sugar mills, with the highest concentration in Malang, Kediri, and Mojokerto regencies. This study concludes that the development of the molasses-based bioethanol industry in Mojokerto is technically and economically feasible with integrated supply chain management support.

Abstract

The use of bamboo as a substitute for wood for construction needs is increasing along with the decreasing availability of wood. Meanwhile, on the other hand the strength and durability of bamboo are different from wood, so it is necessary to conduct research to determine the strength of bamboo before it is used as a raw material for construction needs to replace wood. Based on this, this study aims to determine the types of bamboo found around Palu City and to test the strength of bamboo as a substitute for construction wood or other uses. This study was conducted in July–October 2025 at the Forestry Laboratory and Mechanical Engineering Laboratory of Tadulako University. The raw materials used in this study were types of bamboo that are widely found around Palu City aged 4–5 years. The tools used in this study were handsaws, calipers/vernier calipers, ovens, digital scales, and Universal Testing Machines (UTM) for testing the mechanical properties of bamboo. The results showed that the type of bamboo and the position of the base, middle, and tip affected the water content and density of the bamboo studied. The density value of bamboo showed a tendency from the base to the tip of bamboo; the value became higher. The flexural strength of bamboo batu is equivalent to wood of strength class IV, and the flexural strength of bamboo betung and bamboo tali is higher than the flexural strength of wood of the same strength class. The shear and tensile strength values of bamboo are not affected by the type and axial position. The tensile strength values of bamboo studied have met the allowable stress limit of bamboo for tensile stress.

Abstract

This study aims to analyze the effectiveness of pineapple peel waste-based ecoenzymes as liquid organic fertilizer on the height growth of mung beans (Vigna radiata L.). Ecoenzymes are the result of organic waste fermentation with carbon sources from sugar and water, produced through the activity of decomposing microbes. The compounds contained therein, such as enzymes, organic acids, and beneficial microorganisms, play an important role in increasing soil biological activity, improving soil structure, and accelerating the absorption of nutrients by plant roots. The research was conducted in a laboratory experiment using a three-main-treatment design, namely: control without fertilizer, application of pineapple ecoenzyme liquid organic fertilizer, and application of EM4 liquid organic fertilizer as a commercial comparison. Observations were made every two days during a 14-day period, focusing on the variable of plant height increase. The results showed that the pineapple ecoenzyme treatment significantly increased vegetative plant growth, with an average growth of 10.40 cm, higher than the control (6.20 cm) and close to the EM4 results (11.10 cm). These findings confirm that pineapple ecoenzyme has the potential to be an environmentally friendly liquid organic fertilizer alternative, which not only supports plant growth but also contributes to sustainable household organic waste management

Abstract

This research comprehensively evaluates the economic, technological, and environmental feasibility of green hydrogen adoption in Bogor City's transportation sector. Utilizing Techno-Economic Assessments (TEA), Life Cycle Assessment (LCA), and Scenario Modeling, the study compares centralized versus decentralized production pathways. TEA findings indicate that decentralized production is not financially viable, while centralized production with CCS technology shows positive financial potential, underscoring the role of economies of scale. LCA results confirm that green hydrogen offers significant emission reduction potential, up to 90% compared to fossil fuel alternatives, and produces zero emissions at the point of use, though high CCS costs remain a constraint. Scenario Modeling determined that Scenario 3 (high carbon tax, government subsidies, and reduced renewable energy prices) is the most effective pathway for accelerated adoption. Cost-Benefit Analysis (CBA) suggests that long-term non-economic benefits, such as improved public health and reduced air pollution, significantly outweigh high initial infrastructure costs. This study provides a novel, integrated assessment for a high-density urban context, advising policymakers to implement a higher carbon tax and subsidies to expedite the transition.
