To find a house number for humans is very easy, but it becomes difficult when the computer is doing it all. Artificial Neural Network (ANN) is a branching science of artificial intelligence. Artificial intelligence (AI) and Convolutional Neural Network (CNN) is one of the branches of ANN. The data was processed in the form of images sourced from the udfdl.stanford.edu page with a total of 73.257 training data and 26.032 testing data. The data is preprocessed and processed using CNN so that the house number in each image will be automatically tested try the result will appear.</p> Nur Anisa Dewi Arnes Sembiring Kalvin Chiuloto Copyright (c) 2022 Nur Anisa Dewi, Arnes Sembiring , Kalvin Chiuloto https://creativecommons.org/licenses/by/4.0 2022-03-10 2022-03-10 8 1 22 27 10.46880/mtk.v8i1.920 SISTEM PAKAR MENDIAGNOSA PENYAKIT COVID-19 DENGAN MENGGUNAKAN METODE CERTAINTY FACTOR STUDI KASUS (Puskesmas Tebing Syahbandar) https://ejurnal.methodist.ac.id/index.php/methodika/article/view/919 <p><strong>COVID-19 is an infectious disease caused by a newly discovered type of coronavirus. The WHO (World Health Organization) reported that this virus first appeared on December 31, 2019 and the country that was first confirmed was China, precisely in the city of Wuhan. Indonesia became one of the confirmed countries after President Jokowi and Minister of Health Terawan Agus Putranto on Monday, March 2, 2020. Most people who are exposed to COVID-19 experience symptoms such as: fever, respiratory tract infection, loss of sense of smell, coughing runny nose, headaches, sore throats, loss of sense of taste, and nausea.. Previous research is a science to find comparisons and results to find new inspiration for research. Research methodology is a scientific process or method to obtain data to be used for research purposes. Methodology is also a theoretical analysis of a method or method, research is a systematic investigation to increase a number of knowledge. Based on the results of the CF calculation, the value obtained for the Covid-19 disease from the calculation results above can be seen the level of confidence from the results of the diagnosis of the Covid-19 disease, which is 0.97 x 100%, which is 97% with the results obtained, the system identifies that the patient is Covid-19 negative. Based on the results of the analysis and design that have been achieved, it can be applied to apply an expert system application to diagnose Covid-19 disease, where in this application the user can enter and find out the types of symptoms of the Covid-19 disease that the user has and can find out the right handling solution to help dealing with Covid-19</strong></p> Suprianto Sirait Suci Ramadani Anton Sihombing Copyright (c) 2022 https://creativecommons.org/licenses/by/4.0 2022-03-23 2022-03-23 8 1 1 6 10.46880/mtk.v8i1.919 PENERAPAN METODE MODELLING DALAM PENGARSIPAN DOKUMEN DI KPU TOBA https://ejurnal.methodist.ac.id/index.php/methodika/article/view/918 <p><strong><em>The document archiving system at the Toba Regency KPU is still done manually and takes a very long time. The purpose of "Document Archiving Design at the Toba KPU Using the Mixture Modeling Method" is to facilitate the Toba KPU agency in archiving incoming and outgoing letters. The Mixture Modeling method used serves to classify the types of letters based on the categories of letters that exist in the Toba KPU. The implementation of making this filing system uses PHP and MySQl programming.</em></strong></p> Yolanda Y.P Rumapea Rida Silaen Copyright (c) 2022 rida Silaen, Yolanda Y.P Rumapea https://creativecommons.org/licenses/by/4.0 2022-03-10 2022-03-10 8 1 13 17 10.46880/mtk.v8i1.918 SISTEM INFORMASI PEMBAYARAN SPP PADA SMA KATOLIK 1 KABANJAHE https://ejurnal.methodist.ac.id/index.php/methodika/article/view/887 <p><em>SMA Katolik 1 Kabanjahe School is an educational institution under the leadership of YPK Don Bosco KAM that always improves the quality of education services. Like education to find out the SPP payment information service. Efficient, fast, accurate, and secure tuition payment is needed for the administration of the school. For this, we need a system that requires SPP payment processes. At present, the administrative registration process in SMA Katolik 1 Kabanjahe School still uses a manual system and uses Microsoft Exel to process student transaction data. The problem that arises is the number of times the recording process causes a process that requires a long time making financial statements received less effective. The purpose of this research is to build an information system that will help the SPP payment process so that it reduces problems in making reports on cash receipts for the receipt of SPP payments. SPP Payment Information System Application in SMA Katolik 1 Kabanjahe School was designed with several stages consisting of data and information, needs analysis, and system design. The research method uses the waterfall method while the data collection method uses interviews, observation, and literature study. The design of this information system is created using the Visual Basaic.Net application and uses MySQL as its database.</em></p> Santa Lidwyna Br.

One of the causes of the fire is a gas cylinder leak. A fire disaster is a disaster that often occurs in Indonesia. In general, fires are known when the fire has started to appear and grow and the smoke has started to come out, therefore fires can appear at any time no time In trying to extinguish a fire in the event of fire, a fire alarm system was made using Arduino Uno, MQ-2 gas sensor, fire sensor, buzzer, mini water pump. The working method of this fire alarm system is that the MQ-2 gas sensor detects gas, the buzzer sounds, if the fire sensor detects fire and the MQ-2 gas sensor detects gas, the buzzer sounds and the mini water pump releases water simultaneously.</p> Iip Supiyani Nur Arifin Copyright (c) 2022 Iip Supiyani, Nur Arifin https://creativecommons.org/licenses/by/4.0 2022-03-10 2022-03-10 8 1 18 21 10.46880/mtk.v8i1.921
