Forecasting the Amount of Sea Fish Production in North Sumatra in 2018-2019: A Statistical Analysis

Introduction

Forecasting is a crucial activity in various sectors, including the fisheries production sector. It enables us to estimate what will happen in the future, allowing us to make informed decisions and take necessary actions. In this study, we aim to predict the amount of sea fish production in North Sumatra for the next two years, using the double moving average method. This method is widely used in time series analysis to forecast future values based on past trends.

The Importance of Forecasting in the Fisheries Sector

Forecasting is essential in the fisheries sector, as it helps policy makers and stakeholders to anticipate and prepare for changes in fish production. Accurate forecasts can inform decisions on resource allocation, fishing quotas, and conservation efforts. In addition, forecasting can help to identify potential problems and opportunities, enabling the development of strategies to maintain the sustainability of fisheries resources.

Methodology

To achieve our goal, we used secondary data obtained from the Central Statistics Agency (BPS) of North Sumatra. The data analyzed included information from 2007 to 2016, which is a comprehensive enough period to produce accurate predictions. We employed the double moving average method, which involves calculating the average of the current and past values to forecast future values.

Data Analysis

The data analysis involved several steps, including:

Data collection: We obtained the secondary data from the BPS, which included information on sea fish production in North Sumatra from 2007 to 2016.
Data cleaning: We cleaned the data by removing any missing or inconsistent values.
Data transformation: We transformed the data into a suitable format for analysis.
Double moving average method: We applied the double moving average method to forecast the amount of sea fish production in North Sumatra for 2018 and 2019.

Results

The results of the forecasting show that the amount of sea fish production in North Sumatra for 2018 is expected to reach ... tons, while in 2019 it is expected to reach ... tons. These results indicate a decrease in the amount of sea fish production when compared to the previous period.

Additional Analysis and Explanation

It is essential to understand why this decline occurs. Some factors can affect marine fish production, including:

Climate change: Changes in ocean temperature and chemistry can impact fish populations and their habitats.
Excessive fishing: Overfishing can lead to the depletion of fish stocks and damage to marine ecosystems.
Habitat damage: Human activities, such as coastal development and pollution, can harm fish habitats and reduce fish populations.
Fluctuations in market demand: Changes in market demand can affect the price and availability of fish, impacting production results.

By using the Double Moving Average method, we are trying to get a clearer picture of the trend of sea fish production, so that policy makers and stakeholders in the fisheries sector can take appropriate action to overcome this problem.

Conclusion

The results of this study are expected to be an important reference for all interested parties in the fisheries sector, so that they can formulate the right strategy to anticipate a decline in sea fish production and maintain the sustainability of fisheries resources in North Sumatra. Accurate information is crucial for effective decision making and planning in the field of fisheries resource management.

Recommendations

Based on the results of this study, we recommend that:

Policy makers and stakeholders in the fisheries sector should take into account the decline in sea fish production and develop strategies to maintain the sustainability of fisheries resources.
Fisheries management should be implemented to ensure the long-term sustainability of fish populations and their habitats.
Research and development should be conducted to identify new fishing technologies and methods that can help to reduce the impact of fishing on marine ecosystems.
Education and awareness should be raised among fishermen and the general public about the importance of sustainable fishing practices and the impact of climate change on marine ecosystems.

By implementing these recommendations, we can work towards maintaining the sustainability of fisheries resources and improving the welfare of fishermen in North Sumatra.
