Sistem Pakar Diagnosa Hama dan Penyakit Pada Jamur Tiram dengan Metode Case Based Reasoning Berbasis Web

Abstract

Mushrooms are useful plants for humans, mushrooms as one of the food needs that are often hunted by the community. Lately, many people want to cultivate oyster mushrooms, but to cultivate oyster mushrooms is not easy because oyster mushrooms are easily attacked by pests and diseases. Most farmers only mimic the concept of how to grow other oyster mushrooms without knowing how to properly grow oyster mushrooms. Most oyster mushrooms that are stricken with disease are only left to die, this method can potentially spread to other mushroom plants. Another factor that can cause oyster mushrooms to die is in terms of humidity, oyster mushrooms must be cultivated in a humid room because the habitat of oyster mushrooms grows in humid temperatures. With this the authors took the initiative to create a system that can help oyster mushroom farmers know pests and diseases by creating an expert system. Expert system is a system that functions to transfer knowledge from experts and then it is applied to computer programs. In the research conducted using the case-based reasoning method, there are weight values for each symptom, the weight values obtained from experts. After testing 100 data samples, the calculation results get an accuracy value of 93% and a precision value of 93% which shows the system is functioning properly according to expert identification.
