Abstract

Food technology that is increasingly advanced makes people tend to consume fast food, as well as foods that contain chemicals. This causes the tendency of an unhealthy lifestyle and becomes one of the factors that cause stomach disease. Stomach disease can be experienced at the age of children to adulthood. Unhealthy lifestyle means eating patterns that are initially consumptive on healthy foods and then turn into consumptive foods that are less healthy. Not only food, rarely exercise is also likely to cause pain in the stomach. Diagnosing stomach disease is still carried out by conducting face-to-face consultations with health workers, which can take a long time and cost a lot of money. Lack of information on stomach disease sufferers about the symptoms of stomach disease, causes patients not to know the type of stomach disease they are experiencing. This is the goal of research that will build an expert system software that is expected to be able to analyze stomach diseases and help the community, stomach sufferers and health workers in diagnosing types of stomach diseases. The method used in this study is Certainty Factor (CF) or the certainty value of a disease. Expert system software development is done by analyzing software requirements, system user needs. The dataset of this study is the symptoms and types of stomach diseases that occur at the Salido Health Center. The result of the system built is the result of the diagnosis of stomach disease with the percentage of certainty value from the calculation using Certainty Factor. The system will also provide information about the description, causes and prevention of the types of stomach diseases diagnosed. With the construction of an expert system of stomach diseases, it is hoped that this research can be a reference for users in diagnosing stomach diseases. The accuracy results obtained after testing the system is 80%.

Abstract

The body parts that also need to be kept healthy are the teeth and mouth. Because if the part is experiencing problems, it can be ascertained that the body is in a serious problem. Tooth erosion is the most obvious form of impact when this problem is underestimated. Tooth erosion is damage that occurs by involving the hard tissues of the teeth by chemical processes that reduce the function of the teeth themselves. This situation is caused by the lack of a person having their teeth checked by a dentist due to a lack of awareness and attention to dental health, the high cost to go for a consultation, the long queues making it less comfortable and comfortable to wait. Therefore, this study aims to create a system that can represent the expertise of the dentist himself so that whenever and wherever the public can easily consult about dental health. The data used in this study involved a history of patient consultations at the Drg Florentina clinic where 10 patient data with the same diagnosis were taken as samples. The results of this study the system can identify the severity of dental erosion as much as 80%. Therefore, this research can be used as a reference for further research with the same theme.
