Abstract

The agricultural sector plays a strategic role in supporting Indonesia’s food security and national economy. Agricultural productivity in South Kalimantan Province, particularly in Barito Kuala Regency, is strongly influenced by climatic dynamics such as temperature variation, rainfall, and humidity. This study develops a crop yield prediction model for major food commodities (rice, corn, and tubers) based on weather factors using the Naïve Bayes algorithm as a Decision Support System (DSS) to mitigate crop failure risks. The research data were obtained from the Meteorology, Climatology, and Geophysics Agency (BMKG) and the Central Bureau of Statistics (BPS) of Barito Kuala Regency for the period 2018–2023, covering temperature, rainfall, humidity, sunlight duration, and yield production. The research stages include data preprocessing (cleaning, missing value imputation, augmentation, and labeling), machine learning modeling, and performance evaluation using accuracy and weighted F1-score metrics. The experimental results show that the Naïve Bayes model can classify crop yield categories (high, medium, low) with an accuracy of 90% and a weighted F1-score of 0.89. These results demonstrate stable and consistent performance across various climatic conditions. The main advantage of this study lies in the integration of local weather data with a lightweight machine learning model that is computationally efficient and easily implemented in regional agricultural prediction systems. This research provides a tangible contribution to strengthening food security and data-driven agricultural risk management in tropical humid regions such as South Kalimantan.

Abstract

Salah satu kemampuan berpikir formal penting untuk dikembangkan dalam proses pembelajaran matematika adalah kemampuan berpikir kreatif. Berpikir kreatif merupakan kemampuan berpikir yang dapat menghasilkan sesuatu baru dari yang telah ada, menciptakan solusi, dan membuat rencana inovatif. Penelitian ini bertujuan untuk menganalisis efektivitas model pembelajaran kooperatif, khususnya tipe snowball throwing, dalam meningkatkan kemampuan berpikir kreatif siswa. Kajian dilakukan melalui sintesis penelitian terdahulu yang diterbitkan pada jurnal nasional terakreditasi SINTA dan jurnal nasional bereputasi. Berdasarkan temuan penelitian yang relevan, model kooperatif tipe snowball throwing menunjukkan pengaruh positif terhadap peningkatan kemampuan berpikir kreatif siswa, dengan rata-rata peningkatan sebesar 20–30%, siswa mengalami peningkatan dalam memecahkan permasalahan, memahami tujuan permasalahan, mencari beberapa solusi, dan menentukan cara yang tepat untuk digunakan. Secara keseluruhan, hasil sintesis ini menunjukkan bahwa model pembelajaran kooperatif tipe snowball throwing layak diterapkan sebagai strategi pembelajaran aktif untuk meningkatkan kemampuan berpikir kreatif siswa.

Abstract

AbstrakKegiatan pengabdian kepada masyarakat ini dilatarbelakangi oleh masih rendahnya pemahaman konseptual siswa dalam memvisualisasikan struktur dan geometri molekul pada pembelajaran kimia, yang umumnya bersifat abstrak dan sulit dipahami hanya melalui penjelasan konvensional. Untuk mengatasi permasalahan tersebut, kegiatan ini bertujuan meningkatkan pemahaman dan keterampilan siswa kelas XI Madrasah ‘Aliyah Negeri (MAN) Insan Cendekia Kota Palu melalui pemanfaatan perangkat lunak Avogadro sebagai media pembelajaran berbasis komputer. Mitra sasaran dalam kegiatan ini adalah 40 siswa/siswi kelas XI MAN IC Kota Palu pada tanggal 8 September 2025 yang memiliki minat tinggi terhadap pembelajaran kimia. Metode pelaksanaan mencakup tahapan pengenalan konsep dasar Avogadro, pelatihan penggunaan perangkat lunak, praktik langsung dalam membangun dan menganalisis struktur molekul tiga dimensi, sesi diskusi interaktif, serta evaluasi hasil belajar melalui pre-test dan post-test. Hasil kegiatan menunjukkan adanya peningkatan signifikan pada pemahaman konseptual siswa. Rata-rata nilai meningkat dari 60 menjadi 81,76, dengan peningkatan tertinggi pada aspek pemahaman bentuk molekul (dari 53,33% menjadi 91,67%) dan sudut ikatan (dari 46,67% menjadi 100%). Hasil survei kepuasan menunjukkan respons yang sangat positif, di mana 67,5% siswa menyatakan puas atau sangat puas terhadap kualitas materi, 62,5% puas atau sangat puas terhadap penyampaian narasumber, 70% puas atau sangat puas terhadap kemudahan pembelajaran kimia menggunakan Avogadro, serta 77,5% menyatakan puas atau sangat puas terhadap dukungan pihak sekolah dalam keberlanjutan program. Hasil wawancara dan observasi partisipatif juga menunjukkan meningkatnya keterlibatan aktif dan antusiasme siswa selama kegiatan berlangsung. Temuan ini menunjukkan bahwa pemanfaatan perangkat lunak Avogadro efektif dalam meningkatkan pemahaman konsep, keterampilan praktis, dan literasi digital siswa. Kata kunci: avogadro; kimia visual; pembelajaran berbasis komputer; peningkatan pemahaman konsep. AbstractThis community service activity was motivated by the still low level of students’ conceptual understanding in visualizing molecular structures and geometries in chemistry learning, which are generally abstract and difficult to comprehend through conventional explanations alone. To address this issue, the activity aimed to improve the understanding and skills of eleventh-grade students at Madrasah ‘Aliyah Negeri (MAN) Insan Cendekia Kota Palu through the use of Avogadro software as a computer-based learning medium. The target participants consisted of 40 eleventh-grade students of MAN IC Kota Palu, and the activity was conducted on September 8, 2025, involving students with a strong interest in chemistry learning. The implementation methods included the introduction of basic Avogadro concepts, software usage training, hands-on practice in constructing and analyzing three-dimensional molecular structures, interactive discussion sessions, and evaluation of learning outcomes through pre-tests and post-tests. The results of the activity indicated a significant improvement in students’ conceptual understanding. The average score increased from 60 to 81.76, with the highest improvement observed in molecular shape understanding (from 53.33% to 91.67%) and bond angle comprehension (from 46.67% to 100%). The satisfaction survey results showed a highly positive response, with 67.5% of students stating that they were satisfied or very satisfied with the quality of the materials, 62.5% satisfied or very satisfied with the delivery by the instructors, 70% satisfied or very satisfied with the ease of learning chemistry using Avogadro, and 77.5% satisfied or very satisfied with the school’s support for program sustainability. The results of interviews and participatory observations also revealed increased active engagement and enthusiasm among students throughout the activity. These findings indicate that the utilization of Avogadro software is effective in enhancing students’ conceptual understanding, practical skills, and digital literacy. Keywords: avogadro; visual chemistry; computer-based learning; conceptual understanding improvement.
