Abstract

ABSTRAK   Pemodelan transpor ion dalam sistem saraf sangat penting untuk memahami mekanisme potensial aksi dan dinamika membran sel. Penelitian ini menyajikan simulasi dinamika potensial membran akson berdasarkan model Morris-Lecar, yang merepresentasikan aktivitas neuron dengan memasukkan kontribusi utama dari ion K⁺ (Kalium) dan Ca²⁺ (Kalsium). Simulasi dilakukan menggunakan metode numerik ODE45 pada platform Matlab. Model ini mencakup dua variabel utama: potensial membran dan variabel saluran ion (K⁺ dan Ca²⁺), yang diturunkan dari sistem persamaan diferensial. Hasil simulasi menunjukkan bahwa model Morris-Lecar secara efektif merepresentasikan osilasi dan ambang eksitabilitas neuron dalam menanggapi stimulus arus. Pengaruh dominan ion Ca²⁺ terhadap proses depolarisasi serta peran ion K⁺ dalam repolarisasi juga ditunjukkan secara kuantitatif. Dengan pendekatan ini, metode ODE45 terbukti stabil dan efisien dalam menangani dinamika neuron yang kompleks. Studi ini memberikan dasar yang kuat untuk analisis lebih lanjut dalam neurofisiologi komputasional dan pemodelan biologi seluler.   Kata  kunci : Transpor Ion, Model Morris-Lecar, Metode ODE45.   ABSTRACT   Modeling ion transport in the nervous system is essential to understanding the mechanisms of action potentials and cell membrane dynamics. This study presents simulations of axon membrane potential dynamics based on the Morris-Lecar model, which uses K⁺ (potassium) and Ca²⁺ (calcium) ions to represent neuronal activity. The simulations were performed using the ODE45 numerical method on the MATLAB platform. The model comprises two primary variables: the membrane potential and the ion channel variables (K⁺ and Ca²⁺), which are derived from a system of differential equations. The simulation results demonstrate that the Morris-Lecar model accurately represents neuronal oscillation and excitability thresholds in response to a current stimulus. The simulations also quantitatively demonstrated the dominant influence of Ca²⁺ ions on depolarization and the role of K⁺ ions in repolarization. This approach proved the ODE45 method to be stable and efficient in handling complex neuronal dynamics. This study provides a solid foundation for further computational neurophysiology and cellular biology modeling analysis.   Keyword: Ion transport, Morris-Lecar model, ODE45 method.

Abstract

ABSTRAK   Teknologi artificial intelligence (ai) berpotensi meningkatkan kemampuan berpikir kritis dan pemecahan masalah pada mahasiswa, khususnya pada mata kuliah hidrodinamika yang menuntut keterampilan analitis dan pemecahan masalah. Penelitian ini bertujuan menganalisis efektivitas pembelajaran berbantuan gemini dibandingkan pembelajaran konvensional. Metode penelitian menggunakan desain pretest–posttest dengan membandingkan n-gain berpikir kritis dan pemecahan masalah pada tiga kategori kemampuan awal (low, medium, high). Hasil menunjukkan bahwa kelas kontrol dengan pembelajaran konvensional hanya mengalami peningkatan rendah hingga sedang, baik pada kemampuan berpikir kritis maupun pemecahan masalah (n-gain 0,16–0,43). Sebaliknya, kelas eksperimen yang menggunakan ai-gemini mengalami peningkatan signifikan dengan n-gain berada pada kategori sedang hingga tinggi (0,47–0,76). Seluruh kelompok mencapai nilai post-test pada kategori tinggi–sangat tinggi. Temuan ini mengindikasikan bahwa integrasi ai gemini mampu memberikan umpan balik cepat, penjelasan adaptif, dan dukungan konseptual yang memperkuat pengembangan berpikir kritis dan kemampuan pemecahan masalah mahasiswa. Pembelajaran berbasis ai direkomendasikan sebagai alternatif inovatif dalam perkuliahan hidrodinamika.   Kata kunci: Artificial Intelligence, Gemini, Hidrodinamika, berpikir kritis, pemecahan masalah.   ABSTRACT   The use of artificial intelligence (ai) technology has the potential to improve critical thinking and problem-solving skills in students, especially in hydrodynamics courses that require analytical and problem-solving skills. This study aims to analyze the effectiveness of gemini-assisted learning compared to conventional learning. The research method used a pretest–posttest design by comparing n-gain critical thinking and problem solving in three categories of initial abilities (low, medium, high). The results show that the control class with conventional learning only experienced low to moderate improvement in both critical thinking and problem solving abilities (n-gain 0.16–0.43). In contrast, the experimental class that used ai-gemini experienced a significant increase with n-gain in the moderate to high category (0.47–0.76). All groups achieved post-test scores in the high to very high category. These findings indicate that the integration of ai gemini is capable of providing rapid feedback, adaptive explanations, and conceptual support that strengthen the development of students' critical thinking and problem-solving skills. Ai-based learning is recommended as an innovative alternative in hydrodynamics lectures   Keywords: Artificial Intelligence, Gemini, Hydrodynamics, critical thinking, problem solving.
