Abstract

Acute liver disease can affect liver function, but can identify the patient's clinical and physical symptoms. One of the problems faced by society today is the delay in treatment of liver disease patients, most patients do not carry out self-examination until an advanced stage is found. To overcome this problem, we need a system that can determine whether a person is a patient with liver disease, so that they can carry out routine checks as soon as possible and allow liver disease patients to get timely treatment. The system can generate classification with the help of data mining algorithms. In this paper, Liver Patients have been investigated using an Artificial Neural Network model to predict a Liver Patient or not and analysis using ANN with Python was used to determine the effect of input variables based on data in the literature and obtained an accuracy of 74%.

Abstract

The hospital is a place to treat patients who come from various regions with various diseases, because lifestyle and the environment play a role in the course of the disease. Some of the problems that arise in dealing with disease include lack of information about the spread of disease and the percentage level of disease spread in the community. One solution to this problem is the application of the association rule method that looks for patterns or relationships between items in a dataset determined by an a priori algorithm that can search historical data to identify data patterns based on previously identified properties. This research method is quantitative data with primary data taken from medical records of Johar Baru Hospital Jakarta. Which then can be obtained an information on what diseases most often appear together in hospitals so that prevention of these diseases can be done. This study aims to find patterns of disease that are developing in the community. The resulting information can then be used by the hospital to maximize the availability of drugs, complete medical equipment, and rooms in the hospital.

Abstract

Breast cancer is the second leading cause of death in female patients in the world. Breast cancer has caused death in more than 100 countries. Early diagnosis of breast cancer patients is important to reduce the possibility of death. Researchers focus on accurate breast cancer detection, automated diagnostic methods and breast cancer diagnosis. This paper proposes Adam's optimization for Deep Learning Algorithm to classify breast cancer detection. This study aims to overcome the problem of data instability and overfitting, as well as update network weights on deep learning training data. In this study, the authors conducted experiments with a combination of three hidden layers and learning speed to improve classification accuracy. The experiment used the breast cancer data set obtained from the UCI Study: the WBCD data set (Original) while the experimental results showed that the proposed scheme achieved 96.3% accuracy for classifying breast cancer.

Abstract

Currently, competition in the trading business world is very tight, especially in the fast food restaurant industry, such as Nusa Ricebowl & Burger, to attract customer interest in the food products being sold. So a strategy is needed to beat the market, especially in product sales at Nusa Ricebowl & Burger. With the right strategy, it will sell products quickly so that sales can increase to achieve maximum profit so that maximum profit is achieved which is the company's goal. By using Nusa Ricebowl & Burger transaction data, you can find out what products consumers buy the most and can also determine consumer buying patterns. The amount of sales transaction data available, of course, makes it more difficult to analyze data manually, so it must be done with the help of a system so that sales patterns are easily obtained. One common method used to analyze consumer buying patterns is basket analysis or market basket analysis (MBA). The research applies the FP-Growth algorithm in carrying out the data mining process to find consumer purchasing patterns at Nusa Ricebowl & Burger Stores. To find the frequency between items with a support value of 20% and 30% confidence. This is done by looking for a single path that is combined with the Conditional FP-Tree that has been obtained. The overall results obtained from the sales sample data are 22 rules consisting of 2 association rules that meet 20% support and 2 rules that meet 30% confidence. Of the 110 association rule transaction data that met the requirements ≥ 0.30 were: P→H 0.40 (if the consumer buys Aqua, then he buys Nusa Dua) it can be concluded that the Nusa Dua and Aqua menus are the most frequently purchased by consumers together. The rules have generated new information about consumer buying patterns that are not yet known. This can be used to help shop owners maintain good quality for consumers.

Abstract

Kegagalan peralatan dan waktu henti yang singkat dari proses manufaktur sering menyebabkan kerugian ekonomi yang besar bagi perusahaan. Berdasarkan tingkat keparahan degradasi kinerja mesin dan penggalian pengetahuan dari beberapa input, model penurunan kinerja dari berbagai jenis peralatan yang sama, tetapi faktor manusia, mesin, dan lingkungan yang berbeda. Dengan evaluasi efektivitas perawatan pada kebijakan perawatan yang berbeda, biaya relevan, sumber daya, dan strategi perawatan yang optimal dapat ditentukan. Dengan memanfaatkan berbagai model machine learning, pengklasifikasi diharapkan mampu memprediksi kondisi mesin apakah gagal mesin atau tidak gagal mesin sehingga dapat menjadi input dalam mengestimasi biaya pemeliharaan serta peningkatan masa pakai mesin produksi. Pada penelitian ini memanfaatkan model machine learning dengan menggunakan dua algoritma yaitu Support Vector Machine dan Logistic Regression, kedua model tersebut menggunakan teknik Smote untuk mengatasi imbalance class dan menggunakan metode data preprocessing yang sama, kan tetapi mendapatkan hasil yang berbeda, dengan perbedaan persentase sebesar 9%. Sehingga dapat disimpulkan model dengan menggunakan algoritma SVM bisa lebih baik dalam memprediksi kegagalan mesin atau tidak dengan tingkat keakuratan sebesar 93% dibandingkan dengan model menggunakan algoritma Logistic Regression yang hanya menghasilkan keakuratan sebesar 84%.
