Abstract

The Covid -19 virus spread in the world, especially in Indonesia, very fast. This epidemic is of concern around the world because it has a quite bad impact in various sectors. With existing technological advances, the Expert System can assist medical personnel in detecting the Covid -19 Virus. The purpose of the author in conducting the study was to detect the Covid-19 virus as easily as possible with symptom data obtained from patients who had consultations. The Naïve Bayes method is a method that uses probability and statistics that can predict a person's chance of being exposed to Covid-19 in the future based on symptoms experienced in the previous period packed with a web-based program. For comparison, the author uses the Certainty Factor Method. Certainty Factor is a method that aims to determine the certainty value which is based on the previous calculation of CF value by manual calculation. The Naïve Bayes method can group the symptoms obtained from the official WHO website which has been given an indicator of the percentage of someone exposed to the Covid-19 Virus based on the symptom data experienced to determine a person exposed to the Covid-19 Virus. While the Certainty Factor method gets the confidence of someone exposed to the symptoms of the Covid-19 virus by using the calculation indicator on the CF value that has been consulted by the user, which can provide a percentage level of confidence that is 86%.Keywords:Expert System, Covid-19, Naive Bayes, Certainty Factor.

Abstract

Heart disease is a condition when the heart is experiencing a disorder. The forms of disturbance that are experienced are usually various. Usually there is a disturbance in the blood vessels of the heart, heart rate, heart cover, or congenital problems. The heart itself is a muscle consisting of four chambers. That is, the first two rooms are located at the top, the atrium (foyer) to the left and right. Then the other two rooms are at the bottom, namely the right and left ventricles. To provide information on how to diagnose the type of disease and how to control heart disease, an application of an expert system that can represent someone who is an expert in their field is needed to provide solutions to this disease problem using the Case-Based Reasoning method with the Sorensen Coeffient approach. The result of this research is the creation of an expert system for diagnosing heart disease using the Case-Based Reasoning method with the Sorensen Coeffient approach which is able to provide solutions to heart disease.Keywords:CBR, Expert system, Heart Disease, Method Sorensen Coeffient.

Abstract

Seleksi Paskibraka dilakukan pada setiap tahun dengan tujuan mencari putra putri terbaik yang nantinya akan ditugaskan pada upacara peringatan kemerdekaan Indonesia untuk mengibarkan duplikat bendera pusaka. Pada beberapa wilayah, seleksi Paskibraka masih menggunakan perhitungan dengan excel atau perhitungan manual lainnya dalam menentukan keputusan. Perhitungan manual ini tentunya membutuhkan waktu yang lebih lama dan hasil yang dapat kurang akurat. Oleh karena itu, dibuatlah aplikasi sistem pendukung keputusan dengan menggunakan metode Weighted Product(WP) dan Simple Additive Weighting (SAW) yang dapat memberikan nilai akhir penilaian seleksi sesuai dengan kriteria dan bobot yang telah ditetapkan. Hasil dari kedua metode ini nantinya akan dibandingkan agar didapatkan hasil yang terbaik. Hasil dari aplikasi ini berupa perangkingan peserta berdasarkan kecamatannya.Kata Kunci:Sistem Pendukung Keputusan; Paskibraka; Seleksi; Simple Additive Weighting; Weighted Product.
