Forecasting the Mortality Rate of Toddlers at the North Tapanuli District Health Office with the Arima Box-Jenkins Model

Introduction

The infant mortality rate is a crucial indicator of a community's overall welfare. In North Tapanuli Regency, the mortality rate of toddlers has been a pressing concern. With the availability of time series data from January 2005 to November 2010, this study aims to predict the trend of toddler mortality rates in the future using the Arima Box-Jenkins model. This model is a widely used technique in time series analysis, which can help forecast future values based on past data.

Background

The North Tapanuli District Health Office has been working tirelessly to reduce the mortality rate of toddlers in the area. However, the lack of accurate predictions and effective prevention strategies has hindered their efforts. The Arima Box-Jenkins model offers a promising solution to this problem. By analyzing the time series data, this model can identify patterns and trends that can be used to predict future mortality rates.

Methodology

The data used in this study consists of time series data on toddler mortality rates in North Tapanuli Regency from January 2005 to November 2010. The data was analyzed using the Arima Box-Jenkins model, which involves several steps:

Stationarity Test: The first step in time series analysis is to determine whether the data is stationary or not. Stationary data has a constant mean and variance over time, whereas non-stationary data has a trend or pattern that changes over time. In this study, the data was found to be non-stationary.
Differencing: To overcome the non-stationarity of the data, the researcher performed a differencing operation on the data. This involves subtracting each value from the previous value to create a new series.
Parameter Estimation: After differencing the data, the researcher used the smallest square method to estimate the Arima model parameters. This involves finding the best combination of parameters that minimizes the sum of the squared errors.
Model Selection: The researcher selected the most appropriate model based on the smallest mean absolute percentage error (MAPE). The MAPE is a measure of the accuracy of the model, which shows the average absolute error of the percentage of predictions.

Results

The results of this study show that the most appropriate model to predict the mortality rate of toddlers in North Tapanuli is the Arima model obtained. This model was chosen because it produced the smallest MAPE value of 0.074. The MAPE value indicates that the model is accurate in predicting the data, with an average absolute error of 7.4%.

Discussion

The results of this study provide an important picture of the trend of toddler deaths in North Tapanuli and help in formulating a more effective prevention strategy. The Arima Box-Jenkins model can be used by the North Tapanuli District Health Office to predict the possibility of an increase or decrease in the mortality rate of toddlers in the future. With this information, the Health Office can focus on the precise prevention program and maximize efforts to reduce the mortality rate of toddlers in the area.

Conclusion

In conclusion, this study demonstrates the effectiveness of the Arima Box-Jenkins model in predicting the mortality rate of toddlers in North Tapanuli Regency. The model provides a valuable tool for the North Tapanuli District Health Office to develop a more effective prevention strategy. However, it is essential to remember that this model only provides predictions based on historical data. Other factors, such as socioeconomic factors, access to health services, and environmental conditions, can also affect the mortality rate of toddlers. Therefore, further analysis needs to be done by considering these factors to produce a more comprehensive prevention strategy.

Recommendations

Based on the results of this study, the following recommendations are made:

Use of the Arima Box-Jenkins model: The North Tapanuli District Health Office should use the Arima Box-Jenkins model to predict the mortality rate of toddlers in the future.
Development of a prevention strategy: The Health Office should develop a more effective prevention strategy based on the predictions provided by the model.
Consideration of other factors: Further analysis should be done to consider other factors that can affect the mortality rate of toddlers, such as socioeconomic factors, access to health services, and environmental conditions.

Limitations

This study has several limitations, including:

Limited data: The data used in this study is limited to time series data from January 2005 to November 2010.
Assumptions: The Arima Box-Jenkins model assumes that the data is stationary, which may not be the case in reality.
Other factors: The model does not consider other factors that can affect the mortality rate of toddlers, such as socioeconomic factors, access to health services, and environmental conditions.

Future Research Directions

Future research directions include:

Extension of the data: The data used in this study should be extended to include more recent data to improve the accuracy of the predictions.
Consideration of other factors: Further analysis should be done to consider other factors that can affect the mortality rate of toddlers, such as socioeconomic factors, access to health services, and environmental conditions.
Development of a more comprehensive prevention strategy: The North Tapanuli District Health Office should develop a more comprehensive prevention strategy that takes into account the predictions provided by the model and other factors that can affect the mortality rate of toddlers.
