Kehilangan gigi merupakan masalah kesehatan gigi dan mulut yang sering terjadi di masyarakat, salah satunya Edentulous yang merupakan suatu keadaan lepasnya satu atau lebih gigi dari tempatnya. Kehilangan tersebut dapat disebabkan oleh karies, penyakit periodontal, trauma dan atrisi yang berat. Penelitian yang menggunakan metode Forward Chaining ini bertujuan untuk mendapatkan diagnosis Edentul…
The Backpropagation algorithm has a weakness in processing data directly from the experience of experts without knowing the tendency to enter the target. Fuzzy Logic is the right choice in overcoming this, because the function of fuzzy logic is to create a degree of membership where the value of a higher degree of membership in a target can indicate that the data will enter the target. The effe…
Every year there are many students who want to take short semesters but cant take the courses they want due to majors that do not open these courses. Prediction of course demand is the use of programming technology to find out which courses have a lot of interest in the next semester. The a priori algorithm was chosen to predict course demand because of the method's ability to find final result…
Hepatitis is a disease that attacks the liver which can be caused by viral infection or can also be caused by other diseases or other conditions, under certain conditions hepatitis can cause complications if not immediately checked and treated. Diagnosing hepatitis is not an easy thing for the general public. In this case the expert system can help deal with the problem by building a system tha…
In the last few decades the Convolutional Neural Network has had outstanding results in various fields related to pattern recognition, one of which is the recognition of Hiragana's writing. For foreigners, hiragana characters are difficult to understand because they have similar characteristics. This study aims to develop software that can recognize hiragana writing using the Convolutioanal Neu…
As social beings, humans can communicate in two ways, namely verbal and non-verbal. One way of non-verbal communication is to use text. However, communication using text cannot show one's emotions. Therefore, it is necessary to classify texts in Indonesian. The first step in classifying text is to preprocess the data which consists of casefolding, tokenizing, filtering, stemming, then weighting…
Rubber plant farmers often suffer damage asa result of maladies that attack rubber plants, the limitations of one expert on information and counseling about solving problems that farmers experience. This requires a system that has the same abilities as one expert at diagnosing rubber plant disease. One is the expert system. Systems of experts require methods used to support the system's passing…

In 2018 WHO stated that the number of cancer cases and deaths was 18.1 million and 9.6 million deaths, and breast cancer is the 2 largest contributor to the number of cancer in the world. In this research using the Naïve Bayes method because there are advantages, namely considering the assumption of independent variables, where the Naïve Bayes classification assumes that the value of the vari…
Naive Bayes is a classification method that has a good speed processing in process breast cancer classification. But, Naive Bayes method has weaknesses in attributes weighting which assumes that all attribute have the same weight or priority. Absolutely, this has an effect on the value of accuracy produced. Therefore, Particle Swarm Optimization method is used which can give weight value to att…
Grouping or clustering is the process of classifying objects. This information is obtained from data that describes the relationship between objects by using the principle of maximizing similarities between members of one class and creating similarities between classes. One of the grouping methods is the K-Means algorithm. In general, the K-Means algorithm determines the centroid value randomly…
The Learning Vector Quantization (LVQ) method is a classification method that is quite effective and widely used. However, this method has a weakness, namely, each attribute needs to be calculated distance, and the resulting accuracy depends on the initialization of the model, input parameters, and the amount of training data. This affects the resulting accuracy value. Therefore, it is necessar…
