The Indonesian government wanted to determine the transmission of the Omicron virus via immigrants and foreign tourists in Indonesia. Hence, the Omicron transmission Susceptible–Infectious–Recovered model, with parameters of foreign travelers and immigrants was constructed. Then, using the next-generation matrix method, it was discovered that when the number of foreign travelers and immigrants who entered Indonesia (a) is constant and the number of foreign travelers who leave Indonesia (c) varies, the basic reproductive number is R0 = 5.6. Conversely, when the number of foreign travelers and immigrants entering Indonesia (a) varies and the number of foreign travelers leaving Indonesia (c) is constant, the basic reproductive number is R0 = 6.7. © (2023), (Badih/Ghusayni).
