Abstract

Dalam pengenalan wajah menggunakan metode pengolahan citra, dibutuhkan proses segmentasi citra agar dapat dilakukan proses analisis citra selanjutnya. Segmentasi citra dapat dilakukan dengan metode clustering yang memiliki beberapa algoritma berbasis centroid, seperti k-means dan fuzzy c-means. Algoritma k-means sendiri memiliki beberapa varian, salah satunya k-means++ dimana varian ini lebih cerdas dalam memilih inisial centroid dibanding k-means yang memilih inisial centroid secara acak. Algoritma fuzzy cmeans sendiri telah memiliki keunggulan dalam  engelompokan objek yang tersebar secara tidak teratur. Untuk mendapatkan segmentasi yang baik untuk pengenalan wajah, perlu dicari algoritma mana yang dapat menghasilkan segmentasi citra dengan kualitas baik. Sehingga pada penelitian ini, dilakukan penelitian ekspresimen dengan menggunakan citra wajah yang disegmentasi dengan algoritma k-means++ dan fuzzy c-means, kemudian dilakukan evaluasi menggunakan RSME, PSNR dan SSIM. Dari penelitian ini dihasilkan segmentasi citra dengan fuzzy c-means lebih baik dibandingkan hasil k-means++ berdasarkan nilai RSME, PSNR dan SSIM

Abstract

Abstract : Property tax as one source of local revenue has an important role in the progress of the village. Management of property Tax data in general at the village level still uses the usual number management application. While the property tax data needs to be secured because it is classified as confidential data, which has the potential to cause damage if accessed by unauthorized persons. To maintain the security aspects of the information, a cryptographic system can be used which provides encryption and data description facilities. The cryptographic system used is Caesar Cipher's super encryption and Advanced Encryption Standard (AES) -128-EBC. To test the encryption quality of this cryptographic system an experimental method is used, by comparing the ciphertext file size, encryption time, entropi value, correlation value, histogram graph and avalanche effect. The test results obtained by Caesar Cipher and Advanced Encryption Standard (AES) -128-EBC cryptographic systems, have good correlation and entropy values ​​with better avalanche effect values ​​compared to the AES algorithm alone. Keywords: aes-128-ebc, caesar cipher, confidential, encryption, tax Abstrak : Pajak Bumi dan Bangunan sebagai salah satu sumber pendapatan asli daerah memiliki peranan penting dalam kemajuan desa.

Abstract

A computer shop is a place that sells equipment related to computers. As technology advances, people's needs for computer shop locations are also increasing. Computer shops themselves not only sell various computer needs such as hard disks, Random Access Memory, and accessories such as mice and keyboards, some computer shops also sell products in the form of services such as computer servicing, computer assembly, installing software, and buying and selling used computers. Currently, information about computer shops only consists of explanations about the shop and mapping of computer shop location points, there is no information based on completeness categories in the form of product services, computer accessories, computer buying and selling. This means that the public or potential consumers do not know much about the location and search for computer shops in the city of Garut. Because the level of public need for the availability of goods and services will be very necessary, an application system is needed that can help increase store sales and the needs of the public as consumers. The aim of this research is the design and development of web-based computer shop mapping in Garut Regency. The methodology used to design this application is Rational Unified Process (RUP) with several stages of inception, elaboration, construction, and using Unified Modeling Language (UML) modeling. The results of this research are a geographic information system mapping computer shops to help make it easier for users or potential consumers to choose a complete computer shop and recommended computer shop.

Abstract

Hiperkolesterolemia atau dengan kata lain adalah kadar kolesterol yang tinggi akan menimbulkan gangguan kesehatan, jika tidak segera ditangani akan semakin memperburuk kondisi dari penderitannya. Kolesterol sendiri tidak bisa dihilangkan karena merupakan zat penting yang dibutuhkan tubuh. Yang bisa dilakukan adalah mengkontrol agar kadar kolesterol dalam darah tidak melebihi batas normal. Saat ini cara yang dilakukan untuk mengetahui kadar kolesterol adalah dengan invasive yaitu dengan datang ke Rumah Sakit atau menggunakan alat pengukur kolesterol elektronik, cara tersebut dirasa kurang praktis untuk mengetahui kadar kolesterol karena membutuhkan waktu. Oleh sebab itu dengan dibuatnya alat pendeteksi kolesterol non invasive berbasis mikrokontroler Arduino Uno menggunakan sensor inframerah serta photodioda TCRT 5000 dan dihubungkan dengan aplikasi khusus untuk penginputan datanya yang akan dimasukan ke dalam database dapat berfungsi secara optimal, sehingga pengguna atau tenaga medis dapat melakukan langkah pengobatan atau penanganan kolesterol dengan tepat dan efektif. Tingkat akurasi yang dihasilkan oleh alat ini dibandingkan dengan alat kesehatan komersial yaitu sebesar 93.04%, hal ini tentu saja bergantung pada kualitas komponen terutama perangkat sensor yang digunakan.

Abstract

One of the requirements for graduating from the undergraduate level for universities in Indonesia is writing a final project or thesis. In order to graduate, of course, it is greatly influenced by the desire and strong spirit of the students and also the guidance of the supervisor. In determining the supervising lecturer, special attention must be paid to the field. Usually the selection of lecturers for thesis supervisors is determined by the study program through a meeting of lecturers in order to determine which lecturers are considered according to the title of the student and in accordance with the research of the supervisor. However, this method is a bit inconvenient and also quite time-consuming considering the number of students is more than a hundred and continues to grow every year. In this study, the thesis supervisor was classified based on the title proposed by the student. The methodology that will be used in this research is the Cross-Industry Standard Process for Data Mining (CRISP-DM) methodology whose stages are: Business Understanding, Data Understanding, Data Preparation, Modeling, Evaluation, and deployment, as well as using Generative Pre-Technology. trained Transformers 3 (GPT-3)
