Abstract

Climate change has altered rainfall patterns in Indonesia; however, spatially detailed climate classification in Gorontalo Province remains limited. This study aims to identify climate patterns using the Schmidt–Ferguson method combined with spatial analysis. The novelty lies in integrating data consistency testing, quantitative Q index analysis, and GIS-based interpolation to produce spatial climate zoning. This study uses monthly rainfall data from 41 consistent observation stations (out of 48 stations) during 2015–2024, obtained from BWS Sulawesi II and BMKG. Data consistency was tested using the Double Mass Curve method, followed by calculation of the Q index and spatial interpolation using the Inverse Distance Weighting (IDW) method. Results show that rainfall data are highly consistent (R² ≈ 1). The Q index ranges from 7.6 to 119, indicating diverse climate types: very wet (A), wet (B), moderately wet (C), moderate (D), and slightly dry (E). Spatially, wet climates dominate mountainous areas, while relatively drier conditions occur in coastal regions. These findings are applicable for crop calendar planning, irrigation management, and disaster mitigation such as flood-prone and drought-prone zoning. However, the study is limited by uneven station distribution and a 10-year observation period. In conclusion, Gorontalo Province exhibits high spatial variability of climate influenced by topography and geographic location.

Abstract

The increasing volume of corn cob waste in Indonesia poses environmental challenges and reflects underutilized biomass with potential economic value. This study examines the conversion of corn cobs into Bio-CNG through anaerobic digestion and the utilization of fermentation residues as livestock feed within a circular economy framework. The novelty lies in integrating energy production, feed generation, and circular system marketing in a single agro-based model. A laboratory experimental study using a 3×3 factorial Completely Randomized Design (CRD) was conducted, employing Biomethane Potential Tests (BMP) with rumen and methanogenic inoculums at different temperatures and fermentation times (2–6 days). Gas production and digestate composition were analyzed using standard methods, including proximate analysis. Results show substrate degradation up to 55.34%, methane production reaching 3.82% (rumen microbes, 39°C) and 10.79% (methanogenic basis), and total gas production up to 10.29%. Digestate quality improved, with protein increasing from 4.95% to 7.39% and TDN from 53.34% to 55.42%, indicating suitability as ruminant feed. The study is limited to laboratory-scale and short fermentation duration. Practically, this model can support integrated agroenergy systems in rural areas. In conclusion, corn cobs offer significant potential as a dual resource for renewable energy and livestock feed, supporting sustainable circular agriculture.

Abstract

This study examines the effect of Problem Based Learning (PBL) integrated with Information and Communication Technology (ICT) on students' mental models and self-efficacy in elementary school science learning. This study used a quantitative approach with a quasi-experimental nonequivalent control group design. The study population consisted of fourth-grade students in Cluster I, Pariaman Tengah District, in the 2024/2025 academic year, with two classes selected through purposive sampling as the experimental and control groups. Data were collected using a validated mental model test and self-efficacy questionnaire, then analyzed using descriptive and inferential statistics, including prerequisite tests and independent sample t-tests. The results showed that the experimental class obtained a higher mental model post-test score (79.17) than the control class (59.17). Self-efficacy scores increased significantly in the experimental group from 50.54 to 81.08, while the control group only reached 63.75. The results of statistical tests showed a significant difference between groups (p < 0.05). These findings indicate that ICT-integrated PBL is effective in improving students' conceptual understanding and self-confidence, thus becoming a relevant and innovative learning strategy to improve the quality of science learning in elementary schools.

Abstract

This study aims to analyze the implementation of Product-Based Learning (ProdBL) integrated with peer assessment in a bakery practicum and its contribution to student learning interest. The study employed a pre-experimental design with a one-group pretest-posttest approach involving 20 third-semester students of the Culinary Education Study Program. Data were collected using a validated learning interest questionnaire and supported by classroom observations and student reflections. The results of the paired sample t-test showed a significant difference between pretest and posttest scores (t = -2.816, p = 0.011 < 0.05), indicating an increase in student learning interest. The mean score improved from 31.15 in the pretest to 37.65 in the posttest. Qualitative findings revealed that students became more active, confident, and collaborative during the practicum process. The use of watermelon rind as food waste and local palm sugar contributed to meaningful and contextual learning experiences. These findings suggest that the integration of ProdBL and peer assessment can enhance student learning interest and support sustainability-oriented vocational education.

Abstract

This study aims to design multimodal digital materials on energy transformation in primary education in terms of validity, practicality, and effectiveness in improving students’ conceptual understanding. The study employed design-based research by integrating the Rowntree model for the planning as well as  development phases and Tessmer’s formative evaluation (self-evaluation, expert review, one-to-one, small-group, and field test). The subjects of this study consisted of 33 fourth-grade students at SDN 1 Sumber Rezeki. Data were collected through practicality questionnaires, expert validation sheets, and tests, and analyzed using descriptive statistics, paired-sample t-test, and effect size analysis. The validation results showed that the multimodal digital materials were in the highly valid category (94.7%). The practicality test in the one-to-one showed practical category  (71%-80%) and small-group evaluation stages fell into the very practical category (86%–92%). The effectiveness test showed a significant increase in learning outcomes, with the mean score improving from 53.42 (pre-test) to 82.90 (post-test) and an N-gain of 0.59 (moderate category) (t = 8.383, p < 0.05), with a Cohen's d effect size of 1.459, which is classified as a large effect.These findings indicated that the developed multimodal digital materials are valid, practical, and effective in improving students' understanding of energy transformation. This study implies that the integration of multimodal elements in digital learning materials can enhance meaningful and contextual science learning. It also serves as an innovative reference for developing instructional materials aligned with 21st-century learning.

Abstract

Project Based Learning (PjBL) is a learning model that emphasizes active student involvement in the learning process through contextual and meaningful project activities. This study aims to analyze the application of the Project Based Learning (PjBL) model to the concept of global warming and its impact on the knowledge of tenth-grade students. This study used a quantitative approach with a quasi-experimental method and a pretest–posttest control group design. The research sample consisted of two classes: class IA X-1 with 22 students as the experimental class and class IA X-2 with 21 students as the control class, resulting in a total sample of 43 students. The experimental class was given treatment in the form of learning using the PjBL model, while the control class used conventional learning. The research instrument was a knowledge test administered before and after the treatment. Data were analyzed using descriptive statistics and N-Gain calculations. The results showed that there was a difference in knowledge gain between the experimental and control classes. The increase in student knowledge in the experimental class was higher than in the control class, with the N-Gain results being in the moderate to high category. Based on these results, it can be concluded that the implementation of the Project Based Learning (PjBL) model is effective in increasing student knowledge on the concept of global warming.

Abstract

The endangered Salmon-crested Cockatoo (C. moluccensis) is an endangered species endemic to Maluku and faces serious pressures due to habitat loss and illegal trade. As a species that relies heavily on vocal communication, bioacoustic analysis offers an effective, non-invasive approach to support monitoring and conservation. This study aims to analyze and characterize the spectral profile of Salmon-crested Cockatoo (C. moluccensis) vocalizations using the FFT algorithm. Voice recordings were conducted on individuals in their natural and captive habitats using a Zoom H5 Handy recorder. Audio data were processed through noise filtering, normalization, and segmentation stages before being analyzed using computational programming-based FFT to obtain the main spectral parameters. The results show that Salmon-crested Cockatoo (C. moluccensis) vocalizations have a consistent spectral structure with the main parameters being dominant frequency, bandwidth, spectral centroid, and amplitude. Spectral analysis shows variations in frequency characteristics influenced by environmental and individual conditions. The dominant frequency of Salmon-crested Cockatoo (C. moluccensis) behavior in its natural habitat was 1981 Hz, while in captivity it was 2497.9 Hz, both of which are within the main frequency range of ± 1500 – 4000 Hz. These different conditions show that frequency alone is not enough to explain behavior, but must be combined with context (call patterns, social interactions, and other behavioral expressions). The FFT method proved effective in identifying and characterizing vocalization patterns quantitatively. These findings indicate that FFT-based bioacoustic analysis has the potential to be developed as a non-invasive monitoring tool to support the conservation and population management of endangered endemic bird species.

Abstract

Early renewable energy education has become increasingly vital since the urgency of sustainability in the energy sector continues to grow. This study provided a comparative analysis of students’ multiliteracy enhancement between urban and rural schools in the Science, Technology, Engineering, and Mathematics Project-Based Learning (STEM-PjBL) setting. A quasi-experimental design was employed involving 120 students from one urban and one rural secondary school, selected using stratified random sampling. Multiliteracy was measured using pre- and post-tests and analyzed through normalized gain (N-gain) scores. Results indicated that both schools demonstrated moderate improvement in multiliteracy after the intervention. However, the urban school achieved relatively stronger performance compared with the rural school.  It is found that urban students were associated with greater access to digital teaching and learning facilities. Conversely, rural students benefited from rich local knowledge and community practices related to natural resource management, which supported contextual understanding of renewable energy concepts. Future research is recommended to integrate sustainability education at earlier educational stages and further embed renewable energy applications within the formal curriculum to promote sustained multiliteracy development.

Abstract

Science learning in Indonesian schools continues to face structural and instructional challenges, particularly in laboratory management, inquiry-based implementation, science literacy development, and supervision of science instruction. Effective principal leadership plays a crucial role in ensuring that science learning is systematically planned, implemented, and evaluated. This study examines how Ki Hadjar Dewantara’s Among System can be integrated into science learning management to strengthen principals’ instructional leadership. Using a qualitative literature review approach, this study analyzes empirical research on science education leadership and Dewantara’s educational philosophy. The findings indicate that Dewantara’s leadership trilogy ing ngarsa sung tuladha, ing madya mangun karsa, and tut wuri handayani, supports science learning management through strategic laboratory planning, participative supervision of science teachers, collaborative curriculum development, and the promotion of inquiry-based learning. The Among System encourages structured autonomy in scientific exploration while maintaining professional accountability. However, institutional rigidity, limited laboratory facilities, and administrative constraints remain significant challenges. Integrating Dewantara’s philosophy into science learning management provides a culturally grounded and humanistic leadership framework that enhances instructional quality, scientific literacy, and sustainable school improvement.
