Abstract

Abstrak. Banyak permasalahan di lingkungan kehidupan kita yang dapat dibentuk ke dalam model matematika sehingga dapat dianalisis secara matematik. Salah satu permasalahan itu adalah kejadian endemi, seperti transmisi penyakit malaria. Model matematika transmisi penyakit malaria berbentuk system Persamaan Diferensial Biasa (PDB) non linier orde satu. Dalam tulisan ini akan dibahas efektivitas dan efisiensi metode Runge-Kutta orde delapan yang dibandingkan dengan metode Adams Bashforth-Moulton orde sembilan. Selain itu juga akan dicari sifat-sifat, formula, konvergenitas, dan format pemrograman MATLAB dari metode itu. Efektivitas suatu metode bergantung pada error. Sedangkan efisiensi bergantung pada waktu tempuh suatu metode untuk menyelesaikan masalah. Metode pengumpulan data yang digunakan adalah metode dokumentasi dan eksperimen. Hasil dari tulisan ini yaitu sifat dan formula metode Runge-Kutta orde delapan, pembuktian konvergensi metode tersebut secara teoritis, dan format pemrograman yang hasilnya digunakan untuk menentukan metode yang paling efektif dan efisien untuk menyelesaikan model transmisi penyakit malaria. Kata kunci : Efektivitas, Efisiensi, Metode Runge-Kutta, Transmisi malaria.

Abstract

Abstrak. Model sistem kekebalan tubuh terhadap infeksi Mycobacterium tuberculosis telah dikembangkan dan dikemas dalam bentuk sistem persamaan diferensial biasa non linier order satu. Model tersebut sangat komplek sehingga memerlukan metode numeric untuk menyelesaikannya. Salah satu metode numerik yang yang efektif adalah metode Runge-Kutta. Penelitian ini akan merumuskan formula metode Runge-Kutta order sembilan, dan menentukan sifat dari metode tersebut sebelum merumuskannya, serta menganalisis konvergensi dan efektivitas dari metode Runge-Kutta order sembilan bila dibandingkan dengan metode Adam Bashforth-Moulton order sembilan. Metode dikatakan efektif dan efisien bila error yang terjadi pada metode dalam menyelesaikan model semakin kecil (menuju nol) dan waktu yang dibutuhkan metode untuk menyelesaikan model matematika semakin sedikit. Hasil penelitian menunjukkan bahwa metode Runge-Kutta order sembilan lebih efisien dan efektif dibandingkan metode Adam Bashforth-Moulton order sembilan dalam menyelesaikan model sistem kekebalan tubuh terhadap infeksi Mycobacterium tuberculosis. Kata kunci : Metode Runge-Kutta order sembilan, konvergensi, efektivitas, model sistem kekebalan tubuh terhadap infeksi Mycobacterium tuberculosis.

Abstract. Materials to produce fertilizer are NH3 Liquid and CO2 gas. Required CO2 gas should be free from condensation, so CO2 gas is refrigerated in intercooler. In this research, we analyse of mathematic model for heat transfer in fluid with finite volume method. We will review how the CO2 gas cooling process from mathematics model point of view. We will model the equations for CO2 gas cooling process which includes momentum dan energy. After that this model will be discretizatied. For numerical solution, we will use Matlab and Fluent to simulate CO2 gas cooling process. The simulation result using Matlab and Fluent forms will be presented descriptively in charts, tables, and images to show how the distribution process of heat transfer. The result show for error is 0,0087. In conclusion the model accurate for solving heat transfer process in CO2 gas. Key Words : Mathematics Models, Heat transfer, Finite Volume Methode,
