Abstract

Terdapat berbagai macam teknik pengujian otentisitas dan kredibilitas foto yang digunakan pada forensik foto digital. Penelitian ini berusaha melakukan pengujian kinerja deteksi tiga teknik pengujian dalam forensik foto digital, yaitu: jpeg-ghost, histogram equalization-gamma correction, dan error level analysis (ELA) terhadap tiga kategori manipulasi foto digital, yaitu: splicing-duplicate, splicing-erase, serta copy-move. Prosedur Verification yang dipinjam dari metode ACE-V (bidang forensik identifikasi) diterapkan lewat penggunaan lebih dari satu teknik pengujian yang bertujuan menguji hipotesis yang didapat dari temuan hasil pengujian menggunakan salah satu teknik. Dengan demikian, prosedur Verification diharapkan dapat meningkatkan validitas hasil pengujian yang mampu mengungkap temuan yang relevan antar teknik pengujian

Abstract

Pharmacy has a lot of transaction data on the distribution of pharmaceutical supplies, especially drug management. There are several obstacles that occur in the drug supply management system at this pharmacy, one of which is the accumulation of drug stock, where pharmacists find it difficult to determine what drugs should be in stock or not in stock. In order to avoid the accumulation of drugs that exceed the user limit (expired) which will result in losses for pharmacies. For this reason, the authors want to deal with these problems through the Design of a web-based Drug Inventory Prediction Information System using the Itertive Dichotomiser Algorithm method which will predict the stock of drugs that are expected to manage drugs at pharmacies to be wiser in choosing products to sell. In designing information systems Supporting software is also used, namely PHP and MYSQL databases. The final result of this research is, with this information system, it can help pharmacists in supporting drug management so that they can be more selective in choosing the items to be purchased for sale so as to minimize losses that will occur in pharmacies.
