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.

Abstract

This study examines differences in student learning outcomes based on learning models (Problem-Based Learning and Cooperative Learning) and students’ levels of interpersonal intelligence. This study employed a quasi-experimental design using a 2 × 3 factorial framework. This research was conducted in the 2nd semester of the elementary school teacher education study program, the Basic Concepts of Basic Science/Social Studies course at Setiabudi Rangkasbitung University in Banten Province. A total of 100 students participated in the study, with each group including fifty students. The sampling method used, cluster random sampling. The interpersonal intelligence instrument uses a questionnaire with a Likert scale of 1-5 and the learning outcomes of the instrument are multiple choice pre- and post-test questions. This study yielded three main findings. There was a significant difference in learning outcomes between students taught using different learning models (PBL vs Cooperative), as indicated by an F-value of 10.739 and a significance level of p < 0.001. There were also significant differences in learning outcomes among students with high, medium, and low levels of interpersonal intelligence, as shown by an F-value of 23.419 and a significance level of p < 0.001. In addition, there was a significant interaction effect between the learning model and students’ levels of interpersonal intelligence on learning outcomes, as evidenced by an F-value of 8.357 and a significance level of p< 0.006. This study implies that the choice of learning model plays a crucial role in improving learning outcomes, as problem-based learning and cooperative learning contribute in different ways.

Abstract

Limited forage availability due to land conversion has become a major constraint in goat farming development. Therefore, the utilization of agricultural waste as alternative feed is increasingly important, including young coconut husk waste which is abundant but underutilized. However, its high lignocellulosic content, particularly lignin, limits digestibility and nutritional value for ruminants. This study aimed to evaluate the ability of several white-rot fungi to reduce lignin content and improve the cellulose characteristics of young coconut husk waste as a potential alternative feed ingredient. The research was conducted in two stages: fungal selection and optimization of fermentation conditions. The first stage used five fungal treatments, namely Trichoderma sp. TR3, Pleurotus sajor-caju, Pleurotus ostreatus, Trametes versicolor, and Lentinus edodes. Parameters observed included lignin and cellulose contents after 20 days of incubation. The second stage evaluated the effect of incubation period (20, 30, and 40 days) and inoculum volume (0.5, 0.7, and 1.0 mL) using Pleurotus sajor-caju as the selected fungus. The results showed that Pleurotus sajor-caju produced the lowest lignin content (17.93%) and the highest cellulose content (48.80%) compared with other fungi. In the optimization stage, the lowest lignin content was observed in treatment A3B1 (40 days incubation and 0.5 mL inoculum) at 15.47%, while the highest cellulose content was obtained in treatment A2B1 (30 days incubation and 0.5 mL inoculum) at 61.15%. These findings indicate that Pleurotus sajor-caju has strong potential for selective delignification of young coconut husk waste while maintaining cellulose content. Biological fermentation using white-rot fungi can therefore be considered a promising and environmentally friendly approach for improving the quality of lignocellulosic waste as ruminant feed

Abstract

The development of functional meat products has gained increasing attention, particularly through the incorporation of dietary fibers to enhance nutritional value while maintaining product quality. This study aimed to evaluate the effect of adding 3% banana blossom flour (BBF) on the quality characteristics of spent hen meat sausages subjected to refrigeration at a temperature of 4°C over periods of 0, 7, 14, and 21 days. The experiment was arranged in a completely randomized design, with storage duration as the treatment factor and five replications. The parameters observed included moisture content, pH, texture, color (L, a*, b*), microbial counts, peroxide value, and sensory attributes during cold storage. The results showed that storage periods of spent hen meat sausages with BBF addition exerted a statistically significant effect (P < 0.01) on all parameters. During storage, pH value, redness, yellowness, total microorganism, and peroxide value increased, whereas moisture content, lightness, and sensory quality decreased. In conclusion, BBF addition extended the shelf life of sausages, allowing to remain acceptable until 21 days of cold storage, despite a gradual decline in sensory quality associated with increased peroxide values. Moreover, the utilization of BBF facilitates the enhancement of agricultural by-products as part of sustainable food innovation.

Abstract

Rice (Oryza sativa L.) is one of the most important crops as a major source of carbohydrates for the majority of the world's population. However, to date, rice farming in West Kakas District, Minahasa Regency, still faces problems due to pest attacks. The purpose of this study was to determine the types and diversity of insects on rice plants in West Kakas District, Minahasa Regency. The research was conducted in West Kakas Subdistrict, which was determined using the purposive method, at four locations with five observation points. Insects were captured directly using insect nets. The captured insect samples were collected and grouped according to type. The types and population densities of the captured insects were counted and identified, then analyzed for diversity using the Shenon and Wivier formula to obtain the diversity index (H), similarity index (E), richness index (R), and dominance index (C). The results of the study show that there are insect pests and natural enemies (parasitoids and predators). The insect pests consist of 5 orders, 12 families, and 16 species, namely Dolycorus sp, Scotinopharasp., Stenodema sp, Leptocorisa sp, Paraecosmetus sp, Cofana spectra, Recilia sp., Nephotetix sp, Oxya sp. , Anacridium sp, Chilo sp, Parnara sp, Cnaphalocrocis sp. , Orseolia sp , Chlorops sp, and Phyllotretra sp. Meanwhile, natural enemies consist of 3 orders, 9 families, and 9 species, namely Cyrtohinus sp. , sp, Agryophylax sp. , Sepedon sp., Encarsia sp., Menochilus sp. , Ophionea sp. , Paederus sp., Sceliphron sp. and Agriocnemis sp. The results of the Shannon and Wiever diversity analysis are H' = 3.04 or a high diversity index, the richness index R = 4.67 or moderate criterion value, the evenness index E = 0.52 or moderate and unstable evenness index, and the dominance index C = 0.377 or low dominance.

Abstract

The digital transformation of contemporary society has reshaped religious authority, identity construction, and intra-religious interaction. Social media platforms now function as primary arenas for theological negotiation, organizational affiliation, and discursive contestation within religious communities. In this context, intra-religious tolerance—the capacity to accept doctrinal, interpretive, and organizational diversity within the same religious tradition—has become increasingly mediated by algorithmic systems and digitally structured communication environments. Traditional survey-based and ethnographic approaches face limitations in capturing large-scale, real-time patterns of tolerance and polarization. This study develops a comprehensive conceptual framework for measuring intra-religious tolerance through a computational social science approach grounded in big data analytics. Using a qualitative research design based on systematic literature review (2016–2025), thematic synthesis, and conceptual integration, the study bridges scholarship in computational social science, big data methodologies, sociology of religion, and social psychology. The findings propose a multidimensional tolerance model encompassing cognitive, affective, behavioral, and algorithmic-structural dimensions. The article introduces a Big Data-Based Intra-Religious Tolerance Index (IRIT Index) grounded in digital trace indicators such as sentiment polarity, interaction diversity, network modularity, and hostility frequency. The framework contributes theoretically by integrating macro-sociological and micro-psychological theories within computational measurement paradigms, and methodologically by advancing qualitative conceptual modeling within data-intensive research. Ethical considerations, epistemological challenges, and implications for digital governance are discussed.
