Forecasting the Number of Labor Force in North Tapanuli Regency with Periodic Series Methods Based on 2011-2022 Data

Introduction

The North Tapanuli Regency is one of the regions in Indonesia that has been experiencing rapid economic growth in recent years. However, this growth is not without its challenges, particularly in terms of labor force. The increasing number of workforce in the region poses a significant challenge for the local government in terms of providing jobs, education, and training. Therefore, it is essential to forecast the number of labor force in North Tapanuli Regency using periodic series methods based on 2011-2022 data.

Background

The Central Statistics Agency (BPS) of North Sumatra Province has been collecting data on the number of labor force in North Tapanuli Regency since 2011. The data collected is secondary data, which is obtained from various sources, including the BPS. The data is then processed, arranged, and presented in the form of numbers to provide a clear picture of the existing data set.

Methodology

The periodic series method is a statistical method used to forecast the number of labor force in a region. This method is effective in analyzing the trend of data collected for several years. In this study, the semi-flat method is used as a supporting method to increase the accuracy of forecasting results. The data used in this study is secondary data obtained from the BPS.

Results

The results of this study show the projection of the number of labor force in North Tapanuli Regency for 2023 is estimated to reach 168,737 people. Furthermore, for 2024 the number will increase to 171,991 people and in 2025 it is estimated to reach 175,218 people. These results provide valuable information for developing regional economic development strategies, especially in increasing labor capacity and reducing unemployment.

Discussion

Forecasting the number of labor force is a crucial aspect in regional development planning. By knowing the projection of the number of workers, local governments can anticipate the need for appropriate jobs, education, and training. The numbers obtained from this forecast provide valuable information for developing regional economic development strategies, especially in increasing labor capacity and reducing unemployment.

The periodic series method used in this study is very effective because it allows the trend analysis of the data collected for several years. In addition, the use of semi-flat methods as a supporting method also increases the accuracy of forecasting results. Secondary data obtained from BPS guarantees the validity and reliability of information analyzed.

Conclusion

The increasing number of workforce in the next few years shows the potential for positive economic growth in North Tapanuli Regency. However, to take advantage of this potential, local governments need to formulate the right policy. This includes providing relevant skills training, the development of local industries, and creating a conducive business environment. Thus, the existing projection is not only a number, but also as a driver to improve the welfare of the local community.

Recommendation

In facing global and regional challenges, adaptation to changes in the job market is also a key to success. Therefore, collaboration between the government, the private sector, and educational institutions is very important to prepare a quality workforce and ready to compete. With the right approach, North Tapanuli Regency can maximize the potential of its workforce and achieve sustainable growth.

Limitation

This study has some limitations. The data used in this study is secondary data, which may not be accurate or reliable. In addition, the periodic series method used in this study may not be suitable for all types of data. Therefore, further research is needed to validate the results of this study and to explore other methods that can be used to forecast the number of labor force in North Tapanuli Regency.

Future Research

Future research can focus on validating the results of this study using other methods, such as the ARIMA model or the exponential smoothing method. In addition, further research can explore the impact of labor force on regional economic development and the role of local governments in providing jobs, education, and training.
