Abstract

TTS Regency is the second largest regency with the highest population in East Nusa Tenggara. The ratio of general practitioners from 2015 to 2017 is below national standard. Therefore, the TTS regency has experienced a crisis of general practitioners. The research was conducted by taking the number of TTS population of the last eight years. We use the Verhulst model to predict the number of population and propose the ideal number of general practitioners. We found that the number of TTS population is predicted to be 647.815 in 2027. Furthermore, the ideal number of general practitioners in 2027 is 259 people.

Abstract

An increase in the number of cases related to radicalism in Indonesia is an early warning for the government and is very dangerous for the lives of Indonesian people including the Bima community. Therefore, an anticipated strategy is required to determine the best control of the radicalism. This study aims: (1) to determine the attitude of university student radicalism in the City of Bima, (2) build a mathematical model that is in line with the problem of radicalism in the City of Bima, and (3) to construct the reproduction number from the mathematical model of radicalism, and use the to explain the dynamics of the spread of radicalism in the city of Bima. The following results have been obtained: (1) STKIP Bima students' perceptions of radicalism are categorized into three groups, namely the healthy group of 295 people (12%), the neutral group of 1,768 people (72%), and the radicalism (in perception) group of 393 people ( 16%), (2) The mathematical model has been validated against the real data obtained from the STKIP Bima student population in 2019. It shows that if the chance of moving individuals from neutral groups to radical groups is greater or equal with the opportunity of individuals from neutral groups to healthy groups, one person who believes in radicalism can produce four to five new individuals who understand radicalism.

Abstract

In this paper, the mathematical model used is the host-vector model for transmission on of dengue hemorrhagic fever where the host population consists of three compartments, namely susceptible host, infected, and recovered, while the vector population consists of two compartments, namely susceptible vector and infected vector. From this model, an estimate of the basic reproduction number will be constructed with the assumption that the number or humans and mosquitoes infected with the dengue virus grows exponentially with the same growth rate. Applications using field data in the City of Bima obtained an basic reproduction number estimates of . Because the estimated values for the basic reproduction number are greater than one, it illustrates that the spread of dengue hemorrhagic fever in Bima City from 2018 to 2020 is categorized as an epidemic.

Abstract

The spread of covid-19 poses a threat to the transmission of diseases related to the lungs, including TB. TB is one of the main problems that is still easily found in various areas, including Bima Regency, NTB. To find out the dynamics of the distribution and the strategy to solve it, it is necessary to conduct research from various aspects, including the mathematical aspect. One of the important indicators in mathematical epidemiology is the basic reproduction ratio. Therefore, this study was conducted to determine the estimated value of the basic reproduction number, and the relationship between the rate of cure of the disease and the basic reproduction value using a mathematical model for the dynamics of the spread of TB tuberculosis in Bima Regency. The method used in this study is the early-take off-rate method, which is estimating the initial growth of the infected population. Bima Regency is included in the TB disease emergency category because from January 2020 to May 2022, 1,245 new cases of infected people were found, and the occurrence of the covid-19 pandemic in the last two years has contributed to a decrease in TB disease cases in Bima Regency. Based on the results of research data analysis, the spread of TB disease in Bima Regency is included in the endemic category with the indicator value of being in the range between 2 and 3. The spread of TB disease in Bima Regency will disappear from the population if the value of the disease transmission rate is below 0.168 with the healing rate is greater (or the treatment period is shorter).
