Abstract

Salah satu aspek penting yang harus dikembangkan sejak dini adalah kemampuan numerasi. Pada jenjang PAUD kemampuan numerasi merupakam kemampuan dasar yang mencakup pemahaman bilangan, pola, pengukuran, geometri dan analisi data sederhana hingga penerapan konsep matematika dalam kehidupan sehari-hari. Penelitian menggunakan pendekatan kuntitatif dengan desain quasi experimental dengan menggunakan desain non-equivalent kontrol group design. Sampel penelitian berjumlah 20 orang anak terdiri atas 10 anak kelompok eksperiment dan 10 anak kelompok kontrol. Kelompok eksperiment memperoleh pembelajaran STEAM berbasis budaya lokal Bugis Makassar, sedangkan kelompok kontrol menggunakan STEAM secara umum. Data dikumpulkan melalui observasi, tes dan dokumentasi berdasarkan indicator numerasi kurikulum Merdeka. Analisis data menggunakan N-Gain dan uji-t dua sampel independent. Hasil penelitian menjukkan rata-rata N-Gain kelompok eksperimen sebesar 0.86 berada pada kategori tinggi, sedangkan kelompok kontrol memperoleh rata-rata N-Gain sebesar 0,55 berada pada kategori sedang. Hasil Uji Hipotesis menunjukkan nilai t = 14,4444 dengan p = 0,000 < 0,05 sehingga H0 ditolak H1 diterima. Dengan demikian pembelajaran STEAM berbasis budaya lokal Bugis Makassar terbukti memberikan pengaruh signifikant dan lebih efektif dalam meningkatkan numerasi anak usia 5-6 tahun dibandingkan dengan pembelajaran STEAM secara umum. Integrasi konteks budaya lokal seperti rumah adat Bugis Makassar, kapal pinisi dan lipa sabbe menjadikan pemebelajaran Numerasi lebih konkret, konstektual dan bermakna bagi anak usia dini.

Abstract

Self-directed learning and creative thinking are essential 21st-century skills that need to be optimally developed in mathematics education. This study aimed to investigate how the implementation of a metacognitive learning model influences students’ self-directed learning and creative thinking skills. A quasi-experimental design was employed involving ninth-grade students at SMP Telkom Makassar. The population comprised all ninth-grade students, with data collected using a self-directed learning questionnaire and a creative thinking skills test. In the experimental class, the mean self-directed learning score after the treatment was 3.59 with an average normalized gain of 0.48, and 100% of students achieved at least a moderate category. The mean creative thinking score reached 83.86 with an average gain of 0.77, and 90.3% of students exceeded the minimum mastery criterion. In contrast, the control class obtained a mean self-directed learning score of 3.39 with an average gain of 0.39, and 96.7% of students reached at least a moderate category. The mean creative thinking score in this class was 72.50 with an average gain of 0.61, and 56.7% of students surpassed the minimum mastery criterion. Inferential statistical analysis revealed that the metacognitive learning model had a significant effect on students’ self-directed learning and creative thinking. These findings underscore the importance of process-oriented mathematics instruction that emphasizes self-regulation and creativity. Therefore, metacognitive learning is recommended as an effective instructional strategy to enhance students’ learning independence and creative thinking skills.

Abstract

This study aims to examine problem-solving abilities in early childhood through the use of geometric block media at TK Islam Athirah Bukit Baruga. Problem-solving ability is an essential cognitive skill that needs to be developed from an early age through meaningful learning experiences, one of which is play-based activities. Geometric block media were selected because they are constructive in nature and allow children to explore shapes, plan, try various strategies, and find solutions to problems that arise during play activities. This study employed a descriptive qualitative approach. The research subjects were children in Group B at TK Islam Athirah Bukit Baruga, with classroom teachers serving as supporting informants. Data were collected through observation, interviews, and documentation. Data analysis was conducted through data reduction, data display, and conclusion drawing, while data validity was ensured through source, technique, and time triangulation. The results indicate that the implementation of geometric block media was carried out through the stages of play environment preparation, pre-play activities, during-play activities, and post-play activities. These stages created a conducive play environment and stimulated children’s problem-solving abilities. Children demonstrated the ability to identify simple problems, try various problem-solving strategies, and evaluate outcomes through block play experiences. Social interaction during play also contributed to the development of children’s thinking skills. These findings are consistent with Piaget’s and Vygotsky’s theories, which emphasize the importance of concrete experiences and social interaction in children’s cognitive development.

Abstract

Biochar is a solid product derived from biomass pyrolysis with considerable potential as an alternative energy source and functional material. One of the key parameters influencing biochar characteristics is pyrolysis temperature. This study aims to model and optimize the effect of slow pyrolysis temperature variations on the yield and calorific value of biochar produced from corncob feedstock. The pyrolysis process was conducted using a slow pyrolysis method at temperatures of 350, 400, 450, and 490 °C, with a low heating rate and a residence time of 60 minutes. The resulting biochar was characterized through proximate analysis, while its calorific value was determined using a bomb calorimeter. The relationship between pyrolysis temperature and both yield and calorific value was modeled using polynomial regression. Multi-response optimization was subsequently performed using the desirability function approach. The results indicate that increasing the pyrolysis temperature leads to a reduction in biochar yield, while simultaneously increasing fixed carbon content and stabilizing the calorific value at higher temperatures. The regression model demonstrated strong agreement with the experimental data, with a coefficient of determination (R²) of 0.9582, indicating excellent model fit. Multi-response optimization revealed that the optimal pyrolysis temperature was 350 °C, producing a biochar yield of 79.71% and a calorific value of 7050 cal/g. This study provides a scientific basis for determining optimal slow pyrolysis operating conditions to enhance the valorization of corncob waste as a biochar-based renewable energy resource.

Abstract

Landslides are among the most frequent natural disasters in Indonesia, posing significant threats to human safety and infrastructure, particularly in regions characterized by steep topography and high rainfall intensity. This study aims to spatially analyze landslide susceptibility using machine learning algorithms and to identify the most influential conditioning factors contributing to landslide occurrences. The research was conducted in Kabupaten Luwu Utara, located in Sulawesi Selatan, utilizing recorded landslide events from 2015–2025. The analysis incorporated biophysical and geospatial variables, including rainfall, humidity, and the Normalized Difference Vegetation Index (NDVI). The study employed a quantitative explanatory approach with predictive modeling based on Random Forest (RF), Support Vector Machine (SVM), and Artificial Neural Network (ANN) algorithms. The dataset was constructed as a balanced binary classification of landslide and non-landslide events. Model performance was evaluated using multiple metrics, including accuracy, precision, recall, F1-score, ROC-AUC, and precision–recall curves to ensure comprehensive assessment. The findings indicate that the Random Forest model achieved the highest overall accuracy, while the Artificial Neural Network demonstrated superior capability in detecting landslide occurrences within the testing dataset. However, the relatively modest AUC and Average Precision values suggest limitations in the models’ discriminative performance. Variable importance analysis revealed that rainfall is the most dominant conditioning factor, followed by humidity and NDVI. Overall, the machine learning approach successfully represents landslide susceptibility spatially. Nevertheless, further model optimization and integration of additional relevant variables are required to enhance predictive reliability and to support robust disaster mitigation and early warning systems.

Abstract

Groundwater often contains iron (Fe), which can cause a metallic taste, yellow color, iron bacteria growth, and turbidity. One method used to reduce iron content in water is the use of activated carbon. However, activated carbon has disadvantages such as long separation times and requires filtration equipment that can filter activated carbon. This study aims to produce magnetic activated carbon from cassava peel composite with magnetite to be used in reducing iron concentration in water. The methods used in this study included carbonization, activation with 2.5% KOH activator, activated carbon and magnetite composite with a 2:1 ratio, FTIR analysis, quality analysis through water content, ash, and iodine adsorption capacity tests in accordance with SNI 06-3730-1995 standards, surface area analysis using a BET instrument, and Fe adsorption application with varying times. The results showed that magnetite activated carbon was successfully synthesized, as confirmed by FTIR analysis, which indicated the presence of Fe-O bonds in the activated carbon and its ability to be attracted to a magnetic field. The adsorption effectiveness of magnetic activated carbon reached 77.38% with a contact time of 30 minutes. The quality test results of magnetic activated carbon did not meet the SNI 06-3730-1995 standard, with an iodine adsorption capacity of 620 mg/g. This study provides an overview of magnetic activated carbon composites  from cassava peel, which have advantages in the separation process between adsorbent and adsorbate after adsorption. Research on the optimization of the manufacturing process for magnetic activated carbon that meets SNI standards is urgently needed.
