Kombinasi Damerau Levenshtein dan Jaro-Winkler Distance Untuk Koreksi Kata Bahasa Inggris
Get PDFWriting is one of the efforts made by the writer to express ideas and ideas to others. But sometimes when writing, there are many errors in typing spelling, especially English spelling, resulting in errors in capturing the meaning and meaning of the writing. To overcome this problem, we need a system that can detect word spelling errors. Damerau Levenshtein and Jaro Winkler Distance Algorithms are algorithms that can be used as a solution to detect English typing errors. From the test results, it can be concluded that the Damerau Levenshtein and Jaro-Winkler Distance are able to optimally detect word mismatches and look for similarities of words compared. The Damerau Levenshtein Distance works by finding the smallest distance value, while the Jaro-Winkler Distance works by finding the greatest proximity value of the string being compared. Using this algorithm, errors in writing the spelling of words can be minimized.

Penerapan Keamanan Penyampaian Informasi Melalui Citra dengan Kriptografi Rijndael dan Steganografi LSB
No full textKomunikasi telah menjadi bagian dari kehidupan manusia dan menjadi hal yang sangat penting seiring dengan berjalannya waktu. Dalam proses komunikasi, banyak terjadi kegiatan pertukaran informasi. Ada kalanya informasi yang dipertukarkan tersebut bersifat penting dan rahasia sehingga keberadaannya tidak boleh diketahui oleh pihak yang tidak berkepentingan. Dengan berkembangnya teknologi informasi, banyak cara yang dilakukan agar kerahasiaan informasi tersebut dapat terjaga agar tidak jatuh ke tangan pihak-pihak yang tidak berkepentingan. Kriptografi merupakan kajian ilmu dan seni untuk menjaga suatu pesan dan meningkatkan aspek keamanan informasi. Selain menggunakan teknik kriptografi, menjaga kerahasiaan informasi juga dapat dilakukan dengan menggunakan metode steganografi, dimana dalam metode ini informasi yang akan dikirimkan disisipkan melalui sebuah media (gambar, musik, suara, video). Dalam penelitian ini, peneliti merancang sebuah aplikasi dengan menerapkan kombinasi steganografi teknik Least Significant Bit untuk menyisipkan informasi pesan dalam media Gambar bitmap 24 bit dan kriptografi Rijndael yang digunakan untuk melakukan enkripsi terhadap gambar bitmap sehingga informasi pesan dapat diamankan dari pihak-pihak yang tidak berkepentingan.Communication has been a part of human life and become very important over time. In the process of communication, a lot going on information exchange. There are times when the information exchanged is important and so secret that its existence should not be known by unauthorized parties. With the development of information technology, many ways in which the confidentiality of the information that can be maintained in order not to fall into the hands of parties who are not interested. Cryptography is the study of science and art to keep a message and to improve aspects of the security of information. In addition to using cryptographic techniques, confidential information can also be done by using steganography, which in this method of information to be transmitted is inserted through a media (images, music, sound, and video). In this study, researchers designed an application by applying a combination of Least Significant Bit steganography techniques to insert messages in the media information 24 bit bitmap images and Rijndael cryptography is used to encrypt the message bitmap image so that information can be secured from the parties who are not interested.</jats:p

Get PDFVaginal discharge is a common gynecological symptom that often indicates various diseases, but its diagnosis frequently requires specialized medical examinations. The limited access to healthcare professionals and the lack of awareness can lead to delayed diagnosis and ineffective treatment, potentially resulting in more severe health complications. This research aims to develop an artificial intelligence (AI) system capable of identifying common vaginal discharge diseases, such as Bacterial Vaginosis, Candidiasis, and Trichomoniasis, based on a series of user-provided symptoms. The study utilizes a rule-based expert system approach with the forward chaining method to process symptoms logically and arrive at a probable diagnosis. The system\u27s knowledge base is constructed from established medical literature and expert physician consultations to ensure high accuracy and reliability. The developed system was tested using a set of clinical cases, achieving an accuracy rate of 92.5%, demonstrating its effectiven ss as a preliminary diagnostic tool. This AI-based system is expected to serve as a valuable early screening instrument, helping to increase access to gynecological health information and facilitating timely medical intervention for women, particularly in areas with limited medical resources
Pemanfaatan Algoritma Porter Stemmer Untuk Bahasa Indonesia Dalam Proses Klasifikasi Jenis Buku
Get PDF. Stemming is the process of mapping and decomposition of various forms (variants) of a word to essentially find the root word. This process is also referred to as the conflation. Stemming process has been widely used in the activities of the information retrieval (search information) to improve the quality of the information obtained. Stemming works by employing words taken froma dictionary and the USAge of the basic rules of affixes. Porter stemmer for Indonesian or commonly referred as Tala stemmer uses the rules of basic analysis to find the root of a word. Tala Stemmer does not use a dictionary in the process. Instead, it uses a rule-based algorithm. In this study, the principal issue raised is how to make the process of classification/determination of the book/library materials in a library with a fast and effective manner in order to minimize error in determining the type of books. The solution is to utilize the method used by the porter stemmer for stemming Indonesian
Implementasi K-Means Clustering Pada Sistem Pakar Penentuan Jenis Sayuran
Get PDFIndramayu is one of the regencies in West Java Province that produces food crop production in the agricultural and plantation sectors. Many people work in the agricultural sector, one of which is by growing vegetables on their land. Planting vegetables on land in the Indramayu area often experiences problems, for example the land used is not in accordance with the type of vegetables grown. Some farmers have difficulty in evaluating land due to their lack of understanding of the land to be planted so that farmers rely on the system of planting habits that they usually do. The wrong land selection can result in energy and financial losses used for maintenance. Vegetables will develop imperfectly, even vegetables can die because of the inappropriateness of the land used. This study aims to assist farmers in determining what types of vegetable crops can be planted on their land using the k-means clustering method. There are 7 data criteria used for processing k-means so that later it can produce output a recommendation of vegetable types that can be planted by farmers according to the criteria they enter into the system. The results of this study produce an expert system that can provide information about vegetables selected according to the criteria selected by each user and with this system, ordinary people can find out how the selection of types of vegetables is practically on the land to be planted with vegetables
