Abstract

An Expert System can be interpreted as a composition of data and information obtained from an expert or experts which is then processed by a system to be able to solve a problem according to the method used by experts or experts. One of the applications of expert systems is in the medical field, namely in the diagnosis of disease. In the research carried out, the design and creation of an expert system was created as problem solving to help diagnose mental disordersschizophrenia which begins with determining the symptoms to determine the type of mental disorder. In its design, this expert system uses the Simple Additive Weighting algorithm to determine the weight of each symptom experienced by the patient. Then the algorithmDempster Shafer to calculate the confidence value for the symptoms experienced by the patient.

Abstract

NodeMCU is an open source IoT platform, NodeMCU ESP8266 can be used for Internet of Things (IOT) because the facilities are equipped with Wi-Fi, RFID is a process of identifying objects or objects using radio frequency, this device is widely sold in stores online at a very low price. The type of research used in this research is qualitative research, while the data collection method used is observation andto study, the design method uses the method postage type. This system tests every piece of hardware used and tests the software from a specific functional perspective. The result of this study is the teacher attendance system using Microcontroller NodeMCU ESP8266 replace the manual attendance recording model in the attendance book by writing the entry and rturn hours and filling in the teacher's signature with id card attached to the device RFID connected to microcontroller NodeMCU ESP8266. Thus, reducing the occurrence human error when recap attendance, and reduce paper use.

Abstract

Teachers are one of the most important components owned by schools in sustaining life, which is a challenge for the management of educational institutions to be able to provide an appropriate, effective and efficient decision in managing data in an increasingly competitive business world that encourages schools to work harder. in improving the quality of their schools. The Decision Support System or SPK for determining subject teachers with the (SAW) method produces a system that can determine an option that can assist the head in making decisions. The simple additive weighting (SAW) method applies a weighted average to calculate the amount of production as the final result.

Abstract

One of the causes of the failure of hybrid corn cultivation activities is pests and diseases which are the result of complex or unbalanced interactions between the three components in weak aquatic ecosystems, ferocious pathogens and deteriorating environmental quality. With that, it is necessary to have an application that can help farmers to take care of corn plants so that they are not attacked by pests and diseases. The application system created in this study is an expert system that can analyze the types of diseases in corn. The expert system in this study uses the Forward Changing method. This expert system is expected to be able to assist farmers in solving farmer problems in detecting corn disease by making applications using WEB, with MySQL and Xampp databases.

Abstract

The era that is increasingly developing requires that we have to keep up with the times that are increasingly developing. Meant in medical science, in detecting disease must also follow the current developments. Digestion is one of the organs that exist in humans created by God. The digestive system is present in the body, it is difficult to detect any disease that is in the digestive tract. With this expert system, it is able to make it easier to detect digestive diseases with the help of information technology. And the data makes it easier for medicine to detect this disease. By making applications using WEB, with MySQL and XAmpp databases. By using the Forward Chaining method.

Abstract

This research is motivated by problems in Siamporik Village who have good celery planting skills, but lack knowledge about this celery plant disease. In the village of Siamporik, the skill of growing celery is due to the lack of detecting celery disease which makes the harvest unsatisfactory. To reduce yield losses, an expert system for diagnosing sop leaves (celery) was created so that it can detect plant diseases, using the Forward Channeling method, using the Web as an application, and using MySQL and Xampp databases.
