Abstract

Tuberculosis (TB) is the second leading cause of death after coronary heart disease. The bacterium type Humanus of Mycobacterium tuberculosis causes the infectious illnessTB. According to WHO, in 2018 Indonesia had 8% of TB cases, the third highest after India (27%) and China (9%). Therefore, efforts are needed to reduce the number of cases and deaths due to TB, in line with efforts to achieve point 3 of target 3 of the SDGs, namely ending the TB pandemic. This study uses the Geographically Weighted Poisson Regression (GWPR) model approach with the aim of analyzing the factors that influence TB, so that preventive interventions to reduce TB cases can be carried out. The data used in this study is secondary data in the form of data on the number of TB cases in 2018 obtained from the Ministry of Health (Kemenkes RI) and the Central Agency of Statistics (BPS). The observation unit is 34 provinces in Indonesia. Based on the smallest Akaike Information Criteria (AIC) value, the best GWPR model is obtained with Adaptive Bisquare weighting. Each province has a different model. The GWPR model in West Java Province which has the highest number of TB cases in Indonesia is . The results of the analysis show that the number of poor people has a very significant influence in almost all provinces in Indonesia. While this is going on, a considerable impact can be seen in the proportion of unfit homes and the percentage of unsanitary food processing facilities (TPM). Provincial governments in Indonesia can consider the results of modeling with GWPR in formulating strategies to reduce the number of TB sufferers in their regions

Abstract

Life test data analysis is a statistical method used to analyze time data until a certain event occurs. If the life test data is produced after the experiment has been running for a set amount of time, the life time data may be type I censored data. When conducting observations for survival analysis, it is anticipated that the data would conform to a specific probability distribution. Meanwhile, to determine the characteristics of a population, parameter estimation is carried out. The purpose of this study is to use the linear exponential loss function method to derive parameter estimators from the exponential distribution of two parameters on type I censored data. The prior distribution used is a non-informative prior with the determination technique using the Jeffrey’s method. Based on the research results that have been obtained, application is carried out on real data. This data is data on the length of time employees have worked before they experienced attrition with a censorship limit based on age, namely 58 years, obtained from the Kaggle.com website. Based on the estimation results, the average length of work for employees is 6.29427 years. This shows that employees tend to experience attrition after working for a relatively long period of time.
