Abstract

Penyakit Parkinson merupakan salah satu dari serangkaian jenis penyakit dengan angka kematian yang cukup tinggi dengan jumlah kematian sampai pada jumlah jutaan nyawa di seluruh dunia setiap tahunnya. Angka kematian tersebut cenderung meningkat karena kurangnya informasi tentang gejala awal dan bahaya dari penyakit parkinson itu sendiri, sehingga diperlukan suatu sistem yang dapat memberikan informasi tentang penyakit parkinson dan cara penanggulangannya karena kurangnya informasi deteksi dini. penyakit Parkinson menggunakannya. Masalah ini dapat diatasi dengan teknik berbasis sistem pakar, yang dapat melakukan deteksi berdasarkan gejala yang dialami pasien. Salah satu pendekatan yang dapat diterapkan pada aplikasi teknis sistem pakar adalah Teorema Bayes, yaitu suatu cara mendefinisikan ukuran kepastian tentang suatu fakta atau aturan yang menggambarkan tingkat kepercayaan yang dimiliki seorang pakar tentang masalah yang dihadapi. Perancangan dan penerapan pendekatan Bayesian pada sistem pakar untuk deteksi dini gejala penyakit Parkinson berjalan dengan baik dan menghasilkan jenis kategori penyakit Parkinson yang dialami oleh pengguna sistem, berdasarkan gejala yang dialami dan gejala yang dipilih oleh pengguna.

Abstract

Hemodialysis patients with diabetes face a significantly higher risk of mortality compared to those without diabetes. Accurate prediction of mortality in this patient population is crucial for guiding clinical decision-making, improving patient outcomes, and optimizing resource allocation. Hemodialysis is a procedure for cleaning the blood from the waste products of the body's metabolism. this is one of modality to treat end stage kidney disease. Diabetes mellitus is a significant contributor to the global burden of chronic kidney disease (CKD), and patients with diabetes undergoing hemodialysis are at a higher risk of mortality compared to those without diabetes. Identifying factors that influence mortality risk in this population can aid in clinical decision-making and improve patient outcomes. Dialysis is performed on patients with kidney failure, both acute kidney failure and chronic kidney failure. This study is aimed to predict the mortality risk of hemodialysis patients with diabetes. The Taiwanese hemodialysis center enrolled a total of 665 hemodialysis patients. The prediction is based on Decision Tree. Compared with K-Nearest Neighbor, linear discriminant, Logistic Regression, and Ensemble, Decission Tree performed better. As for related medical variables like parathyroid surgery, urea reduction ratio, etc., they play a much smaller role in mortality risk factors than diabetes and cardiovascular disease. Diabetes

Abstract

IEC TC10 is the most widely used Dissolved Gas Analysis (DGA) measurement dataset nowadays. Many DGA-based studies have been carried out using conventional methods and methods based on Artificial Intelligence Techniques (AITs). DGA is a diagnostic test performed on power transformers to detect and diagnose potential faults. The test involves analyzing the gases that are dissolved in the transformer oil, which can provide important information about the condition of the transformer. DGA is a widely used technique for transformer monitoring and maintenance in the power industry. However, this dataset is not perfect. There are still many problems in this dataset, one of which is the problem of missing value data. This problem will be significant if not appropriately handled. More reliable data from DGA measurement results is an in-dispensable reference in diagnosing faults in power transformers. This study focuses on dealing with the problem of missing value data using the Tertius algorithm, then testing the results using the J48 and Random Forest algorithms. The results obtained are pretty significant. Of the total 56 missing data, 36 could be predicted perfectly. And received the results of measuring accuracy using the J48 method of 62.73% and the Random Forest method of 70.71%. This result shows that the approach we applied is relatively good for handling missing values in IEC TC10 datasets.

Abstract

The determination of the composition of personnel in an organization, especially in the activities of the Branch Conference (Musran) of the Muhammadiyah Branch Executive of Belian Village, is still done manually and tends to be subjective. This has the potential to cause inefficiencies and internal conflicts in the decision-making process. This research aims to develop a web-based decision support system (SPK) that can help the management selection process objectively by using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The TOPSIS method was chosen because it is able to provide the best alternative ratings based on its proximity to positive and negative ideal solutions. The five main criteria used in decision-making include: organizational experience, level of education, loyalty to the organization, leadership, and availability of time. The system is designed using the PHP programming language and MySQL database. The results of the implementation show that the system is able to produce recommendations for a more systematic, transparent, and accountable management structure. With this TOPSIS-based SPK, the deliberation process can run faster and more efficiently without eliminating the principle of democracy in the organization. This research is expected to be an innovative solution in adaptive and sustainable information technology-based organizational governance.
