Maternal Mortality Rate (MMR) is a metric used to assess a region's maternal health status. Maternal death occurs when a woman dies during pregnancy or until 42 days after to the pregnancy itself or its handling. It does not count if the death occurred as a result of an accident or injury. There are number of factors that cause maternal death, one of which is the direct factor that still dominates up to now on. In this study, MMR modeling in Bali was conducted in 2019 by using 6 factors that are thought to be influential. Poisson Regression method is used to determine the factor that cause maternal death. Based on this study of maternal death rate in Province of Bali, it shows that the percentage of pregnant mother visits K1 (X1) and the percentage of obstetric complication cases (X2) are significant towards the variable.

The Covid-19 pandemic caused many people starting to switch to buying and selling online, some of them use Shopee e-commerce. The aim of this study is to analyze the factors that influence customer satisfaction with service quality and to analyze Shopee's service quality using confirmatory factor analysis and e-servqual analysis. The variables of this study are divided into seven dimensions of e-servqual, namely efficiency, fullfilment, system avaibility, privacy, responsiveness, compensation, and contact, with a total of 23 indicators. This study took a sample of 126 Shopee user respondents in Bali Province who had made transactions at least 3 times until 2021. The results of the factor analysis show that there really are seven dimensions that affect the quality of online services. The results of the e-servqual analysis obtained the value of consumer perceptions of service quality is 7.82 , this value was included in the satisfied category. The factors that require focus of attention are the dimensions of system availability, need to improve the system so that the server does not down easily during heavy traffic.

The problem of transportation is a problem of distributing goods from several sources to several destinations with the aim of minimizing shipping costs. Distribution activities in a company sometimes experience problems in transportation problems so that a model is needed to determine the optimal distribution using the transportation model. This study aims to determine the route of distribution of beras putri sejati 25 kg in UD Sinar Jaya Abadi so that optimal expenses can be obtained using improved exponential approach and zero suffix method. Based on the calculation results, both methods produce the same three distribution path. The first distribution channel is from Agen Monang Maning to Toko Mekar Sari and Subur Jaya. The second distribution line from the Agen Gatsu Barat to UD Mas Ayana and Toko Dharma. The third line from agen Gianyar to UD Sinar Wangi, Toko Sari Artha, UD Amertha, and Toko Ayu Mega with optimal distribution costs of Rp 1.575.815.00. The difference or efficiency of the total costs incurred in the distribution before and after optimization by UD Sinar Jaya Abadi Rp 499,190.00 or 24%.

Small Area Estimation (SAE) is a statistical technique for estimating the parameters of a sub-population with a small sample size. SAE aims to improve the accuracy of parameter estimation, with indirect estimation. This study aims to determine the best method between empirical best linear unbiased prediction (EBLUP) and spatial EBLUP methods (with a queen contiguity weighted matrix) in estimating per capita expenditure per sub-district in Bali. The results of this study indicate that the best SAE method in estimating per capita expenditure per sub-district in Bali is the EBLUP method with the smaller mean squared error. The EBLUP estimation results are significantly influenced by three variables, namely the population, public primary schools, and families using PLN. The sub-district with the highest per capita expenditure in Bali is Denpasar Selatan sub-district. Meanwhile, the sub-district with the lowest per capita expenditure was Abang sub-district. Since the EBLUP model is better than SEBLUP model, this indicates that per capita expenditure per sub-district in Bali is not influenced by its neighbors.

Diabetes mellitus is a non-contagious disease that causes the increas of death rates in Indonesia. This study aims to determine the causality between Age, Occupation, Cholesterol effects of Age, Occupation, Cholesterol Levels, and Blood Pressure Risk of Diabetes Mellitus (DM). The population in this study were all patients at the Beru Public Health Center, with a sample of 200 patients. The analytical method used in this research is Path Analysis with the help of directly or indirectly. The results showed that age and blood pressure had a direct positive effect on cholesterol levels and blood pressure, and age, cholesterol levels and blood pressure also directly affected the risk of developing DM. Age and occupation also affect the risk of developing DM indirectly.

Asthma is defined as a chronic inflammatory disease of the respiratory tract. Since 2013, Bali ranks sixth out of thirty three provinces in Indonesia for the most asthma patient. This study has a purpose to examine the influential factors on the cure rate of asthma patients and determine the best model using the stepwise method. To determine the survival rate of asthma patients, a statistical method that involves censored data is used by applying the Cox Proportional Hazard regression. The data used in this study were medical records of asthma patients who were hospitalized at the Wongaya Regional General Hospital in Denpasar for the period January , 2019 to April , 2020. The analysis of this study discovered that significant variables for the survival of asthma patients were age and disease.

Convenience of the airline passengers are the most important thing for I Gusti Ngurah Rai Airport Authorithy. An exact forecast method is needed to predict the numbers of passenger in the future. There are two types of forecasting methods; triple exponential smoothing and Fuzzy Time Series Ruey-Chyn Tsaur, however based on the research Fuzzy Time Series Ruey-Chyn Tsaur is better than triple exponential smoothing due to a small error MAPE (Mean Absolute Percentage Error) of 2,4% and plot is close to actual data.

Erratic raifall in the future has a major effect on life. Extreme rainfall can result in vaarious natural phenomena that have a negative impact in various fields work. The aim of this research is to find the best rainfall forecastng model in Bali using ARIMAX modeling, namely the transfer function model with an indeks Nino 3.4 as the input series. The transfer function model is a time series model that combines the regression approach and the ARIMA model for its error. Forecasting results suggest that the rainfall is linearly related to the Nino 3.4 indeks in the previous month. The best rainfall forecasting model has a value Akaike information criterion (AIC) is equal to 1334,629.

Imbalanced data is a problem that is often found in real-world cases of classification. Imbalanced data causes misclassification will tend to occur in the minority class. This can lead to errors in decision-making if the minority class has important information and it’s the focus of attention in research. Generally, there are two approaches that can be taken to deal with the problem of imbalanced data, the data level approach and the algorithm level approach. The data level approach has proven to be very effective in dealing with imbalanced data and more flexible. The oversampling method is one of the data level approaches that generally gives better results than the undersampling method. SMOTE is the most popular oversampling method used in more applications. In this study, we will discuss in more detail the SMOTE method, potential, and disadvantages of this method. In general, this method is intended to avoid overfitting and improve classification performance in the minority class. However, this method also causes overgeneralization which tends to be overlapping.
