ABSTRAK-Titi laras merupakan tangga nada yang digunakan pada jenis alat musik karawitan (gamelan) yang merupakan salah satu seni kebudayaan Jawa Barat. Karena kesenian merupakan salah satu unsur budaya yang bersifat universal, maka kesenian tersebut perlu dilestarikan.Fisher-Yates merupakan teknik pengacakan pada soal sehingga soal yang keluar akan berbeda dan bisa dihasilkan tanpa pengulangan dan duplikasi. Fuzzy Tsukamoto merupakan metode yang digunakan dalam pengambilan keputusan untuk menentukan skor pada akhir kuis. Untuk menentukan berapa nilai tertinggi dalam kuis adalah dengan cara menghitung x ꞊ waktu dan x ꞊ nilai, proses perhitungan dilakukan dengan cara menghitung variabel-varibel Fuzzy Logic yang telah ditentukan. Dari penelitian ini dapat ditemukan bahwa Fisher-Yates mampu menentukan solusi pengacakan yang tidak berganda dan pengacakan objek yang variatif. Fuzzy Tsukamoto memiliki akurasi yang cukup baik antara perhitungan berdasarkan sistem dan perhitungan secara manual, meskipun tidak menunjukan hasil yang 100% sama pada masing-masing perhitungan.Rentan nilai antara perhitungan sistem dengan perhitungan manual mempunyai rentan yang berbeda pada setiap nilainnya.

The more rapid and large number of electronic documents stored in University library repositories or Departments, such as scientific works from academicians including theses, research reports, etc., are available in the digital version. In the process of grouping the thesis title automatically it is hoped that it can help policy makers such as the head of the study program. In this case the researcher uses fuzzy c-means algorithm which can group data in clusters so that the data of a cluster has a high level of equality with each other. In the application there is a text mining method which is a development of data mining that can be applied to overcome thesis grouping problems or research data. The result is a web that can classify research data / thesis data with a total accuracy of 96%. This number is the accuracy given based on the performance of the fuzzy c-means algorithm on the system.

Security issues and data confidentiality are very important in the digital and internet era today. Important files circulating on the internet, both in the form of documents, images, and videos need to be supported with good security. This article aims to secure files by utilizing steganography technology, both in encryption and decryption of the file. The method used was the Advanced Encryption Standard (AES) which was applied to Stego-Object. Experiments were done on document files with extensions .doc, .xlsx, .pdf, and .txt, also on image files with extensions .jpeg, .png, and. bitmap. The experimental results showed that AES can encrypt and decrypt quite effectively without changing the quality of files both images and documents. This research could develop for video files.
