Abstract

Climate change is a global issue requiring a strong scientific understanding, particularly of atmospheric dynamics and the factors driving rising global temperatures. However, physics learning on this topic remains dominated by theoretical approaches, limiting students’ opportunities to analyze real-time data. This study aims to develop an Earth Nullschool-assisted learning e-module on climate change materials as an interactive, contextual digital learning medium that supports 21st-century skill enhancement. This research employed a research and development (R&D) method using the 4D development model, comprising define, design, develop, and disseminate stages. The study was limited to the development stage, as the main objective was to produce a valid and feasible model. The research subjects were grade X students of SMAN 10 Kota Jambi, selected using random sampling. The instruments included validation questionnaires from material, media, and pedagogical experts, as well as student response questionnaires. Quantitative data were analyzed using a Likert scale, while qualitative analysis was obtained from comments, critiques, and suggestions from validators and teachers. The results show that the e-module received a “very feasible” rating from the three experts and a positive response from the teacher and students. Thus, the Earth Nullschool- assisted e-module meets feasibility criteria as learning medium for climate change topic.

Abstract

The advancement of digital technology in education demands the availability of teaching materials that facilitate independent, interactive, and student-centered learning. In line with the implementation of the Independent Curriculum, the use of digital learning media is an alternative to increase student engagement in the physics learning process, which has traditionally been considered abstract and difficult to understand. This study aims to develop an interactive physics e-module based on guided inquiry on the Nature of Physics and Occupational Safety and to determine its level of validity, practicality, and effectiveness. The study used the Research and Development (R&D) method with a 4D model that includes the define, design, develop, and disseminate stages. The study was conducted at SMA Negeri 8 Jambi City with 35 students of grade X Phase E as subjects. The research instruments were validation sheets from material experts and media experts, questionnaires on teacher and student practicality, and questionnaires on student effectiveness. Data were analyzed descriptively quantitatively using percentages. The results showed that the e-module obtained a very good level of validity with a percentage of validation from material experts of 81.95% and media experts of 89.00%. The practicality level obtained a percentage of 94.7% based on teacher assessments and 87.3% based on student assessments. The effectiveness level reached 89.3%. These results indicate that the interactive physics e-module based on guided inquiry developed meets the criteria of validity, practicality, and effectiveness, making it suitable for use as a learning medium to support the implementation of the Independent Curriculum

Abstract

This study aims to review the effectiveness of the PBL model combined with the simulation of PhET in improving students' creative thinking skills on alternative energy materials. The study was conducted through a review of 19 selected articles from 49 relevant studies, based on the suitability of the research variables, the quality of the journals, and the clarity of the methodologies. The analysis showed that PBL improved students' learning outcomes, concept understanding, and creativity, while the PhET simulation helped visualise abstract concepts interactively. However, few studies have developed specialised PBL-based modules integrated with PhET to train creative thinking on alternative energy topics. Therefore, this study provides novelty by emphasising the importance of the direction of development of PBL-PhET modules as innovative teaching materials that support the learning needs of the 21st century.

Abstract

Penelitian ini bertujuan untuk mengevaluasi efektivitas platform berbasis awan Google Earth Engine (GEE) sebagai instrumen studi pendahuluan untuk menganalisis dinamika iklim regional dan lokal di Indonesia. Metode penelitian yang digunakan adalah studi literatur sistematis dan analisis eksploratif terhadap dokumentasi teknis serta katalog data GEE dan uji kemampuannya GEE. Hasil penelitian menunjukkan bahwa GEE mampu merevolusi pengolahan data geospasial melalui arsitektur komputasi paralel yang memungkinkan ekstraksi tren suhu permukaan (Land Surface Temperature), anomali curah hujan, dan perubahan tutupan lahan selama lebih dari beberapa dekade. Sintesis data dari berbagai wilayah di Indonesia mengonfirmasi adanya tren pemanasan suhu permukaan dalam sepuluh tahun terakhir yang berkorelasi dengan fenomena Urban Heat Island dan deforestasi. Data satelit sawit global Year of Planting (YoP) diolah menggunakan Google Colab dan Python untuk memetakan umur perkebunan kelapa sawit di Kabupaten Muaro Jambi. Peta yang dihasilkan dapat mendukung pengelolaan perkebunan serta analisis dampaknya terhadap lingkungan dan iklim lokal. Kesimpulannya, GEE merupakan platform yang sangat efektif dan efisien untuk mendukung kebijakan mitigasi serta adaptasi perubahan iklim berbasis bukti di tingkat daerah maupun nasional.

Abstract

Rainfall is a crucial meteorological parameter that directly affects maritime activities and port operations, particularly in coastal regions. Tanjung Perak Port, as one of the busiest ports in Indonesia, is highly vulnerable to weather disturbances due to rainfall variability. This study develops a rainfall prediction model based on machine learning using the Random Forest algorithm optimized with the Synthetic Minority Over-Sampling Technique (SMOTE) to address data imbalance. Daily meteorological data for 2013-2024 were obtained from NASA POWER, including rainfall, minimum and maximum temperature, relative and specific humidity, wind speed, and surface pressure. Model performance was evaluated using Mean Absolute Error (MAE), Mean Squared Error (MSE), and Root Mean Squared Error (RMSE). SMOTE improved the model's ability to identify high-intensity rainfall events. The combined 2024-2025 evaluation produced an MAE of 1.457 mm, an RMSE of 1.819 mm, and R² of 0.861. The model therefore captures seasonal rainfall patterns and has potential as a decision-support tool for weather-risk mitigation at Tanjung Perak Port.

Abstract

Pemodelan curah hujan menjadi tantangan besar bagi model iklim. Project simulasi CORDEX-SEA melakukan downsacle dari model iklim global dan  menyediakan serangkaian model iklim regional  yang beresolusi tinggi dan terlengkap untuk Asia Tenggara. Terdapat kesenjangan yang cukup besar dalam literatur penelitian mengenai evaluasi performa model curah hujan dalam simulasi ini. Sebagian besar evaluasi yang ada hanya berfokus pada aspek spasial. Penelitian ini bertujuan mengevaluasi performa temporal periode tahun 1976-2005 terhadap sembilan model hujan pada database CORDEX-SEA dan dibandingkan dengan data referensi GPCP dan data reanalisis ERA5. Evaluasi kemampuan model dilakukan dengan menggunakan skor Taylor dan bantuan koding Python. Hasil penelitian menunjukkan bahwa tidak ada model yang secara konsisten berkinerja baik di semua aspek dan sub wilayah penelitian. Namun model NorESM1_d seringkali mengungguli model lainnya, diikuti oleh HadGEM2_a dan HadGEM2_c. Sebagian besar model di wilayah Laut Cina Selatan dan setengah dari model di wilayah Indonesia memiliki kemampuan rendah. Berdasarkan korelasi siklus tahunan dan analisis Transformasi Fourier (FFT), rata-rata ensemble CORDEX-SEA mengungguli semua model, tetapi tidak dalam analisis tren dan analisis dengan plot wavelet. Temuan ini memberikan wawasan berharga mengenai pemilihan model hujan yang tepat untuk analisis proyeksi iklim di seluruh Asia Tenggara berdasarkan analisis aspek temporal.
