Pagar Alam is a city with the aim of utilizing technology that is quite high, it can be seen from the public interest, with the ownership of plantations such as salak fruit. Based on the results of observations obtained if there is a problem at the time of harvest the community takes action directly to the agricultural service even though the obstacle is caused by a lack of understanding of plantations. So researchers consider that an expert system is needed to identify the quality of this fruit, the development of this expert system utilizes the advantages of the forward chaining method, forward chaining is a process that begins by describing the collection of data (facts) that are very accurate to conclusions (search) with the support of data starting from input information (if) preliminary to conclusions (then). The programming language used is PHP programming language, supported by MYSQL database. The stages of system development using the waterfall method are preceded by analysis, design, program code creation, testing and support or maintenance. The test is carried out to measure the validity of the system using the black box testing method.
