Identification of the development of special interests and talents needs to be done in order to find out the potential of students. This knowledge is needed by the teacher when providing counseling guidance to students in order to know the types of special interests and talents of students. This study aims to identify the development of special interests and talents in students based on the characteristics of special interests and talents appropriately. In this study using the Certainty Factor method where this expert system can assist experts in identifying the development of special interests and talents based on the characteristics of special interests and talents in students. Followed by calculating the level of accuracy with the results of the counseling guidance teacher analysis. The results of the testing of the Certainty Factor method were successfully applied by comparing the data with the system that had been designed so that a good level of accuracy was obtained from the results of the system calculations with expert decisions of 80% of the 5 test data. This expert system application can be used as an alternative in identifying the development of special interests and talents in students
Teeth and mouth are parts of the body that cannot be separated, where the teeth are in the oral cavity so that if there is interference with the teeth it will affect the mouth. Knowledge to recognize dental and oral diseases from an early age is very much needed to be able to maintain healthy teeth and mouth. Lack of knowledge about these oral and dental diseases will result in severe damage to teeth and mouth. This study aims to measure the severity of oral disease and provide a diagnosis of oral and dental disease so that later it can be used as a reference for consultation with a doctor. The method used in this research is Forward Chaining to represent the rules of 27 symptom facts and 8 diseases described by experts. The results of testing for this method are as many as 10 patient data were diagnosed to get the same result as the doctor's analysis so that the accuracy rate is 80%. The expert system designed with the Codeigniter Framework can provide insight by being able to identify the disease suffered by patients and measure the severity of the oral and dental disease suffered.
Caries disease in human teeth is a disease that permanently destroys the inner walls of teeth and forms small holes in the teeth. The Indonesian people lack the knowledge to find information and identify tooth decay, which makes many people unaware of the consequences and dangers of this disease. Tooth decay disease is usually caused by three factors. The first factor is teeth and saliva, which are the hosts of microorganisms in the oral cavity. Bacteria and food are the second and third factors. The purpose of this research is to help the public find information about tooth decay, thus forming a branch of artificial intelligence, the expert system. Artificial intelligence is a science that allows you to build computer systems that display intelligence in different ways. An expert system is a computer program or information system that uses some knowledge of an expert. The methods used in this study are the Naive Bayes method and the model's view controller, which are implemented as a database in the PHP Codeigniter framework and MySQL. The data processed in this study is knowledge about the symptoms of dental caries obtained from experts. The test results of this method provide patients with the knowledge necessary to prevent tooth decay, with an accuracy rate of 83.61%. This expert system helps the public to recognize and obtain information about tooth decay. The Expert System can also be used to take the first step in preventing tooth decay.
Dalam memenuhi kebutuhan konsumen, ketersediaan produk kalsium merupakan suatu masalah yang perlu diperhatikan. Barang yang sering terjual yang akan menjadi stock terbanyak, sehingga permintaan barang jadi terpenuhi dan pendapatan juga akan meningkat. Penelitian ini bertujuan untuk memprediksi tingkat pendapatan penjualan produk kalsium di stokies tiens 872, dalam menentukan produk yang akan di sediakan untuk tahun berikutnya. Data yang akan digunakan yaitu data penjualan produk kalsium dari tahun 2018 hinga tahun 2019. Pengolahan data dilakukan dengan menggunakan algoritma monte carlo, kemudian data tersebut diolah dan dibangkitkan menggunakan bilangan acak yang di ambil secara random, setelah itu dikonversi atau di ubah dalam bentuk distribusi dengan mengunakan teknik simulasi untu mendapatkan hasilnya. Hasil yang di dapatkan dalam memprediksi tingkat pendapatan penjulan produk kalsium, dengan cara membuat perbandingan terhadap data penjualan yang banyak terjual yaitu Nutrient High Calcum Powder yang ada pada tahun 2018, dengan hasil simulasi tahun 2018 dengan tingkat akurasi data sebesar 91%, dengan jumlah produk kalsium sebanyak 1367 produk. Kemudian Data Pada tahun 2019 dengan hasil simulasi tahun 2019 dengan tingkat akurasi data sebesar 93% dengan jumlah produk kalsium sebanyak 1667 produk. Dengan tingkat akurasi yang dihasilkan pada penelitian, maka simulasi monte carlo dapat membantu pihak stokies dalam memprediksi pendapatan penjualan berdasarkan data yang sudah diolah, Sehingga penelitian ini mampu memprediksi tingkat pendapatan untuk tahun berikutnya.
Perkembangan pendidikan saat ini dipengaruhi oleh kemajuan teknologi informasi dan komunikasi. Salah satu teknologi informasi yang berperan dalam dunia pendidikan pada masa pandemi COVID-19 yaitu pembelajaran daring. Pembelajaran daring digunakan sebagai penghubung dosen dengan mahasiswa dalam satu jaringan internet yang dapat diakses kapan saja. Media daring yang digunakan yaitu Whatsapp, Google Classroom, Google Meet, Cloud x dan aplikasi Zoom. Penelitian ini bertujuan untuk memprediksi tingkat kepuasan mahasiswa dalam pembelajaran daring dan memberikan kontribusi pada perguruan tinggi dalam mengambil kebijakan yang berhubungan dengan peningkatan kualitas pembelajaran secara daring. Data yang digunakan diperoleh dengan memberikan kuesioner kepada mahasiswa angkatan 2020/2021 sebanyak 110 mahasiswa. Parameter yang terdapat pada kuesioner yaitu komunikasi dosen, suasana pembelajaran daring, penilaian terhadap mahasiswa, penyampaian materi. Naïve Bayes merupakan salah satu teknik prediksi untuk mencari probabilitas sederhana berdasarkan teorema bayes dengan asumsi independensi yang kuat. RapidMiner merupakan salah satu tools yang digunakan untuk pengujian data dan melihat hasil akurasi berdasarkan data keusioner. Hasil dari pengujian dengan menggunakan 80 data training dan 30 data testing menunjukkan akurasi sebesar 90 % yaitu 3 responden menyatakan ketidak puasan dan 27 responden menyatakan puas terhadap pembelajaran daring. Dengan class precision pada prediksi tidak puas memiliki nilai 90 % sedangkan pada prediksi puas memiliki nilai 10 % dan class recall pada true tidak puas memiliki nilai 10 % sedangkan class recall pada true puas memiliki 90 %.
