Digital Image Processing To Detect Yellow Patch (Patch Yellow) on Oil Palm Plants Using the Sobel Algorithm

Introduction

Digital Image Processing: A Powerful Tool in Agriculture

Digital image processing is a process that utilizes computer hardware to manipulate and analyze data in image form. This technology has numerous applications in various fields, including agriculture. In the context of agriculture, digital image processing can be used to analyze the condition of plants without having to do direct physical interaction, which can risk damaging the plant. One important application of image processing is in edge detection, which allows identification of patterns or shapes in the image.

The Importance of Early Detection in Oil Palm Plants

In this study, the main focus is on the analysis of the image of oil palm leaves. Through image processing, we can evaluate the greenish level of the leaves and patterns that are visible, which in turn can help in determining the fertility of oil palm plants. Yellow line disease or known as "patch yellow" can affect plant productivity. Therefore, early detection is very important to minimize losses. The disease can cause significant economic losses to farmers and the oil palm industry as a whole.

Methodology

Descriptive Analysis: A Methodological Approach

The method used in this study is descriptive analysis. Researchers collect leaf samples to be analyzed using image processing software. After sampling, the leaf image experiences several stages, namely preprocessing to prepare data, feature extraction to extract important information, implement the system for data processing, and system testing to ensure the accuracy of the results obtained. Finally, documentation and reports are made from the results of the research.

The Role of Image Processing in Disease Detection

It is essential to note that the leaves infected with yellow line disease show certain patterns similar to patches on their surface. The more patterns identified, the more severe the level of disease. In this case, the Sobel filter-based image processing method is very effective in detecting and identifying these spots on the leaf image.

Image Analysis Using the Sobel Algorithm

The Sobel Filter: A Popular Edge Detection Algorithm

Image analysis using the Sobel algorithm is very popular because of its ability to detect edges well. Sobel filter works by calculating the intensity gradient of the image, thus facilitating the identification of areas that experience significant changes, such as the boundary between a healthy area and infected.

The Importance of Image Quality in Disease Detection

Success in detecting diseases in oil palm plants does not only depend on the algorithm used, but also on the quality of the image obtained. Therefore, it is essential to ensure that the image taken has sufficient resolution and good lighting. By paying attention to these factors, the results of the analysis will be more accurate and reliable.

Results and Conclusion

The Contribution of This Study to Farmers and Researchers

The results of this study are expected to contribute to farmers and researchers in an effort to monitor the health of oil palm plants. With early detection, preventive measures can be taken to overcome disease attacks before spreading more broadly. In conclusion, digital image processing with appropriate methods such as the Sobel algorithm can be an effective tool in monitoring and analyzing plant health, especially in identifying yellow-line diseases in oil palm.

The Future of Digital Image Processing in Agriculture

The use of digital image processing in agriculture has the potential to revolutionize the way farmers and researchers monitor and analyze plant health. With the advancement of technology, digital image processing is becoming more accessible and affordable. Therefore, it is expected that this technology will play a significant role in the future of agriculture, particularly in the detection and prevention of diseases in oil palm plants.
