Abstract

Currently, South Korean culture is very popular with many Indonesians, and the rapid development of Korean culture in Indonesia is currently very widespread and very popular. Many Indonesians even learn Korean to keep up with current trends, but due to the different structure of the language, learning Korean becomes more difficult for most people. The dictionary is an effective guide for translating foreign languages/terms. Conceptually, dictionaries are arranged alphabetically, along with explanations of definitions, uses or translations. This is also required for Indonesian to Hangul Korean translation. Many Indonesian-Korean dictionaries are currently published in printed form, but it is still difficult to use because users have to look up the meanings manually. We need practical and effective new media such as smartphone media. There are many algorithmic methods that can be used to create dictionary applications, one of which is using the Knuth Morris Pratt (KMP) algorithm. With this algorithm, every text to be translated is checked for word search and then a match is found with the appropriate word from the desired word. In this study, the final results of the study found differences in the use of the word hangul in formal and informal forms. In this study, the authors tested the application of the algorithm on an Android-based Indonesian-Korean dictionary application.

Abstract

Watering is one of the jobs that are routinely carried out in plant maintenance which usually causes various problems. One of them is the absence of the same measure of water quantity when watering will result in the plants being treated can experience excess or lack of water, causing the plants to dry out or rot and die. So we need a tool that can help in terms of watering plants. The internet of things-based automatic watering machine for water spinach plantations is expected to be a system to assist farmers in watering especially kale that can detect moisture in the soil and temperature around the land and has scheduling options, automatic fuzzy and manual that can be controlled via the android application. which has been designed and can work based on the selected option. This tool is made using the Sugeno fuzzy logic method because this method is suitable for use in making decisions to find the values ​​of humidity and temperature that fluctuate and are less certain. Based on the results of the study, the average percentage difference in the humidity sensor is 0.016 % and the accuracy (accuracy) on the humidity sensor circuit is 99.98%, while the percentage difference in the temperature sensor is 0.02% and the accuracy (accuracy) on the LM35 temperature sensor circuit is 99.99%.

Abstract

Abstract: Dental and oral health is sometimes a priority for some people, even though dental and oral diseases have a serious impact on general health, because the teeth and mouth are places where germs and bacteria enter so that they are likely to interfere with the health of other organs of the body. Periodontitis is a gum disease caused by bacteria that damages the supporting tissues of the teeth and causes tooth loss. This disease can be avoided if you come to the dentist early. However, the problem that often occurs is that many people only start treatment after periodontitis reaches a chronic stage, so an approach is needed that can assist people in diagnosing periodontitis early, quickly and accurately. An expert system is a system that seeks to implement human knowledge on computers so that computers can solve problems as experts do. Fuzzy Logic Sugeno and Backward Chaining methods are used for calculations because these methods can solve the hypothesis of a problem by measuring one's beliefs. The results of this study are an expert system that can have an output in the form of the name of the disease periodontitis and the degree of certainty of the user's disease. Keywords: expert system, fuzzy logic sugeno, backward chaining, periodontitis Abstrak: Kesehatan gigi dan mulut terkadang memang merupakan prioritas ke sekian bagi beberapa orang, padahal sebenarnya penyakit gigi dan mulut berdampak serius bagi kesehatan secara umum, sebab gigi dan mulut merupakan tempat masuknya kuman dan bakteri sehingga kemungkinan besar dapat mengganggu kesehatan organ tubuh lainnya. Penyakit Periodontitis adalah penyakit gusi yang disebabkan oleh bakteri yang merusak jaringan penunjang gigi dan meyebabkan kehilangan gigi. Penyakit tersebut bisa dihindari apabila datang ke dokter gigi lebih awal. Akan tetapi permasalahan yang sering terjadi adalah banyak masyarakat yang baru mulai berobat setelah penyakit periodontitis mencapai tahap kronis, sehingga diperlukan sebuah pendekatan yang dapat membantu masyarakat dalam mendiagnosis penyakit periodontitis secara dini, cepat dan akurat. Sistem pakar merupakan sistem yang berusaha mengimplementasikan pengetahuan manusia pada komputer agar komputer bisa menyelesaikan masalah sebagaimana yang dilakukan oleh para ahli. Metode Fuzzy Logic Sugeno dan Backward Chaining digunakan untuk perhitungan dikarenakan metode tersebut dapat menyelesaikan ketidakpastian terhadap suatu masalah dengan mengukur keyakinan seseorang. Hasil dari penelitian ini adalah sebuah sistem pakar yang dapat memiliki keluaran berupa nama penyakit periodontitis dan tingkat kepastian terhadap penyakit yang diderita pengguna. Kata kunci: sistem pakar, fuzzy logic sugeno, backward chaining, periodontitis
