Abstract The Increasing need of storing large amounts of data presents a new challenge. One way to address this challenge is to use distributed data storage system. One of the strategies implemented in the distributed data storage system is using the technique of regenerating code. The code used in this technique is based on the algebraic structure of fields. Some studies have also been carried out to create code that is based on the other algebraic structure namely module. In this study, we attempted to assess the implementation of the code module at regenerating technique code. The study showed there is a potential properties code based on module that can be used in regenerating code technique. Keywords: Distributed storage, regenerating code technique, module code

Abstract

Citra landsat (land satellite) merupakan data citra area daratan dan lautan di bumi. Data citra tersebut tersedia dalam Sistem Informasi Geografis (SIG). Banyaknya aplikasi SIG menyebabkan adanya perbedaan kualitas citra satelit landsat. Buruknya kualitas citra satelit yang diperoleh dapat menyusahkan beberapa pihak yang membutuhkan letak geografis dengan jelas. Oleh sebab itu, perlu dilakukan perbaikan kualitas suatu citra satelit. Pada penelitian ini menggunakan dua tahapan metode yaitu dengan transformasi kosinus diskrit dan dekomposisi nilai singular. Tahapan pertama dengan transformasi kosinus diskrit yang bertujuan untuk mengurangi gangguan dasar citra dengan membaginya menjadi beberapa komponen dasar. Tahapan kedua dengan dekomposisi nilai singular yang merupakan metode untuk mengekspos struktur citra sehingga dapat diketahui beberapa properti penting dari suatu matriks. Dengan kedua tahapan tersebut, dapat dilakukan proses perhitungan secara matematis dan aplikatif dalam proses perbaikan kualitas citra satelit. Hasil akhir dari penelitian ini berupa aplikasi perbaikan kualitas citra satelit landsat.Kata kunci: kualitas citra, citra landsat, transformasi kosinus diskrit, dekomposisi nilai singular
