Expert Systems To Determine Disease and Pests in Watermelon Plants Using the Forward Chaining Method

Introduction

In the field of agriculture, diagnosing diseases and pests in watermelon plants is a crucial task that requires expertise and experience. However, with the advancement of technology, expert systems have emerged as a powerful tool to aid in this process. An expert system is a computer-based system that mimics the ability of an expert in solving problems to get the right solution. In this study, we designed an expert system that can help determine the types of diseases and pests in watermelon plants using the forward chaining method.

What is an Expert System?

An expert system is a computer-based system that uses artificial intelligence to mimic the decision-making ability of a human expert. It is designed to solve complex problems by using a knowledge base and inference engine. The knowledge base contains a set of rules and facts that are used to make decisions, while the inference engine applies these rules to arrive at a solution. In the context of disease diagnosis, an expert system can be used to identify the symptoms of a disease and provide a diagnosis based on the user's input.

The Forward Chaining Method

The forward chaining method is a technique used in expert systems to make decisions based on the user's input. It starts with a set of symptoms and uses a knowledge base to match these symptoms with possible diseases or pests. The system then uses a set of rules to narrow down the possibilities and arrive at a diagnosis. In the context of watermelon plant disease diagnosis, the forward chaining method can be used to identify the symptoms of a disease and provide a diagnosis based on the user's input.

Design and Development of the Expert System

The expert system was designed and developed using the PHP programming language version 5.3.5 and MySQL 5.0.7 as a knowledge storage. The system consists of a user interface that allows users to input symptoms and a knowledge base that contains a set of rules and facts used to make decisions. The system uses the forward chaining method to match the user's input with possible diseases or pests and provide a diagnosis.

Analysis and Explanation

The forward chaining method in this expert system serves to process information based on the symptoms inputted by the user. This process begins by identifying the symptoms listed, then the system will match these symptoms with the existing knowledge base. With every answer given by the user, the system will continue to reduce the possibility of a type of disease or pest that may occur up to the most appropriate diagnosis. This is certainly very beneficial for farmers, given the symptoms that are not diagnosed can cause significant losses to the harvest.

Benefits of the Expert System

The expert system provides several benefits to farmers, including:

Improved diagnosis: The system can provide a more accurate diagnosis of diseases and pests in watermelon plants, reducing the risk of misdiagnosis.
Effective handling steps: The system can provide recommendations for the use of precise pesticides or appropriate prevention methods, allowing farmers to take fast and appropriate action.
Increased independence: The system can help farmers to be more independent in dealing with the problems they face, reducing the need for expert consultation.

Testing and Evaluation

The expert system was tested and evaluated using real data about diseases and pests in watermelon plants. The results of the evaluation were compared with the results obtained through the forward chaining process. The evaluation showed that the system was able to provide accurate diagnoses and effective handling steps, demonstrating its potential as a useful tool for farmers.

Conclusion

The application of expert systems to detect diseases and pests in watermelon plants with the Forward Chaining method offers practical and efficient solutions for farmers. With this system, farmers are expected to be more independent in dealing with the problems they face, so as to increase yields and reduce losses due to pests and diseases. Further development of this system will be very useful, both for science and for people who depend on agriculture.

Future Directions

The expert system can be further developed and improved in several ways, including:

Expansion of the knowledge base: The system can be expanded to include more knowledge about diseases and pests in watermelon plants, allowing it to provide more accurate diagnoses.
Improvement of the user interface: The system can be improved to make it easier for users to input symptoms and access the knowledge base.
Integration with other systems: The system can be integrated with other systems, such as crop management systems, to provide a more comprehensive solution for farmers.
