Abstract

Abstrak Tujuan dari penelitian ini adalah untuk membantu pengambilan keputusan dalam penggantian ban truk pada sebuah jasa angkutan darat di Surabaya. Metode yang digunakan dalam penelitian ini menggunakan metode penelitian kuantitatif dan data yang didapatkan, diolah dengan menggunakan logika Fuzzy. Data yang diolah berdasarkan dari surat jalan dari setiap truk serta data penggantian ban dari setiap truk. Hasil penelitian dengan menggunakan logika Fuzzy, dapat memberikan output data berupa sudah layak atau belum layak ban untuk diganti. Faktor yang digunakan sebagai data untuk persamaan logika Fuzzy antara lain jarak dan umur ban. Dengan adanya penelitian ini, maka dapat menghasilkan efisiensi waktu dalam pengambilan keputusan untuk menentukan penggantian ban truk yang berpengaruh juga pada efisiensi biaya operasional. Penelitian selanjutnya dapat dilanjutkan untuk menghasilkan data secara otomatis dalam penggantian ban truk yang digunakan.

Abstract

The development of the digital era has brought significant changes to various aspects of life, including the field of photography. Digital photos offer both advantages and disadvantages, one of which is the ease with which they can be modified using image editing software. This makes it increasingly difficult to distinguish between original and manipulated images. Edited photos can spread widely through social media, causing public concern and doubts about the authenticity of information. Individuals often manipulate images for personal gain or interests. The easy access to image editing software further facilitates this manipulation process. In the field of research, digital image forensics has emerged as a scientific method to verify the authenticity of images through accountable evidence. This study aims to detect forgery in digital photos using that approach. The method employed in this research is metadata analysis with the assistance of an offline tool called JPEGsnoop and online tool Forensically Beta. The results show differences in metadata between the original and manipulated images, indicating that modifications have been made to the image.
