SISTEM PAKAR MENDIAGNOSA PENYAKIT PADA IKAN ARWANA MENGGUNAKAN METODE FORWARD CHAINING DAN DEFTH FIRST SEARCH BERBASIS WEB

Everyone can now find solutions to their problems either in person or through the internet, which can be accessed via a computer or mobile device, thanks to the advancements in contemporary technology. In addition, this technology is used in various end-use industries, including animal husbandry, agriculture, manufacturing, healthcare, and others. One of the problems that often arises for some people is health problems because it is difficult to obtain information about health, how to maintain health, and how to determine the best actions for handling and prevention, especially considering the needs of the community. for animal health technology services, especially arowana fish. By utilizing the PHP programming language, create an expert system for detecting arowana fish disease on the web. develop an online expert system that can support arowana fish keepers and make consultations more effective. using a forward chaining and defth first search approach. advanced chaining This technique is a way to find information or data that reveals conclusions through facts. In DFS, the leftmost node is where the lookup is performed. The search is carried out on the right node if the previous answer is found at the deepest level. In addition to using the HTML and PHP programming languages, black box testing is used to test the arowana fish expert system website. The design carried out by researchers on this website is limited to problem identification, conceptualization, research objectives, analysis of the necessary data, and the creation of an expert system for diagnosis of web-based arowana fish disease
