Forecasting the Production of Cabbage Vegetable Crops and Carrots in Karo Regency 2021 and 2022 Using the Double Exponential Smoothing Brown Method

Introduction

Karo Regency is renowned for its thriving agricultural sector, particularly in the production of various types of vegetables and fruits that are exported globally. Among the leading commodities produced in this region, cabbage vegetables and carrots stand out due to the high level of productivity of local farmers. This not only provides opportunities for farmers but also opens international market access for Indonesian vegetable commodities, especially those from Karo Regency. With the existence of cabbage and carrot production centers, this area has significantly contributed to the country's foreign exchange through exports.

In this study, we utilized secondary data obtained from the North Sumatra Central Statistics Agency, which included information about the amount of cabbage and carrot production from 2010 to 2020. The method employed for forecasting was the Double Exponential Smoothing Brown, which aims to find the parameter and the right form of forecasting equation. Through this approach, we can estimate the amount of vegetable production until 2022.

The Importance of Production Forecasting

Forecasting production results are extremely crucial for farmers and stakeholders in the agricultural sector. By understanding and predicting the potential of production, farmers can make better decisions related to planting planning, use of resources, and marketing strategies. In addition, the government and other related parties can use this information to formulate policies that support the development of the agricultural sector, as well as maximizing the contribution of Karo Regency in the export market.

The significance of production forecasting can be seen in several aspects:

Improved decision-making: By having accurate production forecasts, farmers can make informed decisions about planting, resource allocation, and marketing strategies.
Increased productivity: With a clear understanding of production potential, farmers can optimize their resources and improve crop yields.
Enhanced policy formulation: The government and other stakeholders can use production forecasts to develop policies that support the agricultural sector and maximize the contribution of Karo Regency in the export market.

Double Exponential Smoothing Brown Method

The Double Exponential Smoothing Brown method is one of the efficient forecasting techniques, especially for data that shows seasonal trends. This method works by smoothing data by giving greater weight to the latest values, so that it can produce more accurate predictions. The use of mean absolute percentage error (mape) in this study as a measure of forecasting accuracy shows satisfactory results, so that it can be relied upon for estimated production in the coming years.

The Double Exponential Smoothing Brown method involves the following steps:

Data smoothing: The method smooths the data by giving greater weight to the latest values.
Parameter estimation: The method estimates the parameters of the forecasting equation.
Forecasting: The method uses the estimated parameters to generate forecasts for future periods.

Analysis of Forecast Results

Analysis of forecast results shows that the best parameter used to predict the number of cabbage production is 0.34. With this parameter, we estimate that cabbage production in 2021 reaches 143,519.47 kg and in 2022 it is predicted to be 152,292.37 kg. Meanwhile, for carrot production, the best parameter used is 0.42, which provides a projection of 102,233.32 kg for 2021 and 112,703.96 kg for 2022.

Conclusion

This study provides a clear picture of the potential for cabbage and carrot production in Karo Regency, as well as a strong basis for decision making in the agricultural sector. The ongoing effort to increase the productivity and quality of this commodity is expected to further advance Karo Regency as one of the leading vegetable production centers in Indonesia.

Recommendations

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

Continued research: Further research is needed to improve the accuracy of production forecasts and to identify new opportunities for increasing productivity and quality.
Policy formulation: The government and other stakeholders should use the findings of this study to develop policies that support the development of the agricultural sector and maximize the contribution of Karo Regency in the export market.
Capacity building: Farmers and other stakeholders should be provided with training and capacity building programs to improve their knowledge and skills in production forecasting and decision making.

Limitations of the Study

This study has several limitations, including:

Data limitations: The study relied on secondary data, which may not be comprehensive or accurate.
Methodological limitations: The study used a single forecasting method, which may not be the most accurate or reliable.
Geographical limitations: The study focused on Karo Regency, which may not be representative of other regions.

Future Research Directions

Future research should focus on:

Improving forecasting accuracy: Developing new forecasting methods or improving existing ones to increase accuracy.
Identifying new opportunities: Identifying new opportunities for increasing productivity and quality, such as new technologies or farming practices.
Expanding the scope: Expanding the scope of the study to include other regions or commodities.
