| Abstract: | Ayam merupakan bagian dari hasil produksi sektor pertanian yang penting secara ekonomi di dunia. Infeksi virus Gumboro merupakan salah satu penyakit pada ayam yang menjadi suatu ancaman besar yang harus dicari solusi penanganannya. Penelitian ini terdiri atas penentuan titik tetap bebas penyakit dan endemik, analisis kestabilan menggunakan kriteria Routh-Hurwitz, dan perhitungan bilangan reproduksi dasar (R0) dengan menggunakan matriks next generation. Simulasi numerik digunakan untuk melihat parameter yang memiliki pengaruh besar terhadap dinamika penyebaran penyakit. Pemilihan parameter dilakukan dengan menghitung indeks sensitivitas dari semua parameter terlebih dahulu. Hasil simulasi menunjukkan bahwa dengan menurunkan tingkat penambahan populasi ayam, mengurangi kontak ayam rentan dengan lingkungan terkontaminasi virus Gumboro dan meningkatkan laju kematian ayam akibat penyakit selain Gumboro dapat menurunkan bilangan reproduksi dasar. Chickens are a significant part of agricultural production that is economically important worldwide. Gumboro virus infection is one of the diseases affecting chickens that poses a major threat requiring solutions for its management. This research includes determining disease-free and endemic fixed points, stability analysis using the Routh-Hurwitz criterion, and calculating the basic reproduction number (R0) using the next generation matrix. Numerical simulation is used to observe the parameters that have a large impact on the dynamics of disease spread. The selection of parameters is conducted by first calculating the sensitivity index of all parameters. The simulation results showed that reducing the rate of chicken population increase, decreasing contact of susceptible chickens with Gumboro virus contaminated environments, and increasing the mortality rate of chickens due to diseases other than Gumboro virus could reduce the basic reproduction number. |
