Forecasting Model of Indonesian Crude Oil Prices Based on the Fuzzy Time Series Model Chen Model and Markov Chain Model

Introduction

Indonesian crude oil prices (Indonesian Crude Price (ICP)) have a significant impact on the preparation of the State Budget (APBN) as it is one of the sources of state revenue in the export sector. Therefore, the forecasting of ICP prices is crucial to prepare the APBN better. The ICP data that we observe in the same time and period interval allows us to process it into time series data. In this context, the Fuzzy Time Series method is the choice for the forecasting of the price. This article will discuss the application of the Fuzzy Time Series Model Chen and Markov Chain Model in forecasting Indonesian crude oil prices.

The Importance of Forecasting Indonesian Crude Oil Prices

Forecasting Indonesian crude oil prices is essential for several reasons. Firstly, it helps in preparing the State Budget (APBN) more accurately. The APBN is a crucial document that outlines the government's revenue and expenditure for a particular fiscal year. Accurate forecasting of ICP prices enables the government to make informed decisions regarding revenue allocation and expenditure. Secondly, forecasting ICP prices provides valuable insights for policy makers, investors, and industry players in planning their strategies in the future. It helps them to anticipate potential changes in the market and make informed decisions accordingly.

The Fuzzy Time Series Method

Fuzzy time series is a method that utilizes Fuzzy's principles as a basis for calculating data. This method has been developed through several models, including the Chen model and the Markov Chain model. The Fuzzy Time Series method allows us to capture the uncertainty that often appears in economic data. By using the fuzzy approach, we can overcome the problem of price fluctuations that can occur due to various external factors, such as changes in government policy, international market conditions, and environmental factors.

The Chen Model

The Chen model prioritizes the division of fuzzy intervals that help in the calculation of predictions. This model is based on the concept of fuzzy sets, which are used to represent uncertain or imprecise data. The Chen model is widely used in forecasting applications, including stock prices, exchange rates, and commodity prices.

The Markov Chain Model

The Markov Chain model is more focused on the transition between price status over time. This model is based on the concept of Markov chains, which are used to represent the probability of transitioning from one state to another. The Markov Chain model is widely used in forecasting applications, including weather forecasting, traffic flow, and financial markets.

Comparison of the Chen and Markov Chain Models

In this study, we will compare the two models to predict the ICP during the 2016 to 2022 period. The results of the study show that the Fuzzy Time Series-Markov Chain model showed a better performance compared to the Chen model. This can be seen from the Mean Square Error (MSE) which is within the range of 222.05 to 364.39 and the mean absolute percentage error (MAPE) which ranges from 11% to 15%. These figures indicate that the Markov Chain model is more accurate in predicting ICP prices than the Chen model.

Conclusion

Thus, the use of the Fuzzy Time Series-Markov Chain model can be a more effective alternative in forecasting crude oil prices in Indonesia. The results of this analysis are not only beneficial for the preparation of the state budget, but can also be a reference for policy makers, investors, and industry players in planning their strategies in the future. It is essential to continue to conduct research and development of forecasting models that can adapt to changes in market conditions in order to produce more accurate predictions.

Recommendations

Based on the results of this study, we recommend the use of the Fuzzy Time Series-Markov Chain model in forecasting Indonesian crude oil prices. This model has shown a better performance compared to the Chen model and can provide more accurate predictions. We also recommend the use of other forecasting models, such as the ARIMA model and the LSTM model, to compare their performance with the Fuzzy Time Series-Markov Chain model.

Limitations

This study has several limitations. Firstly, the data used in this study is limited to the 2016 to 2022 period. Secondly, the study only compares the performance of the Chen and Markov Chain models. Thirdly, the study does not consider other external factors that may affect ICP prices, such as changes in government policy and international market conditions.

Future Research Directions

Future research directions include the development of new forecasting models that can adapt to changes in market conditions. This can be achieved by incorporating machine learning algorithms, such as deep learning and reinforcement learning, into the forecasting models. Another direction is to use big data analytics to analyze large datasets and provide more accurate predictions.
