Abstract

Nowadays there are many cases of plagiarism that are becoming our concern. Therefore, the writings on plagiarism are one of the things that is important to be understood by the world of education, to avoid plagiarism. Respect, acknowledge and give credit for the work of others is a necessity in producing writing. We all know that science is developed based on pre-existing science. So that there is no need to hesitate for anyone among Educators when composing scientific papers / written works, mentioning the reference sources. This must be understood as intellectual honesty that will not reduce the weight of our writing. Mention honestly, the source of reference that we use, or quote, so that it will be seen clearly, which parts of our work are ideas or taken from dictionaries, encyclopedias, articles, reports, books, magazines, internet, and others.

Abstract

Video is one the valid evidence if the handling process is in accordance with digital forensic procedures. Closed circuit television is a video sourse that is often used as authentic evidence in court. The authenticity of the video is something that is often doubted by certain parties. For this reason, this discusses how to detect the authenticity of video as digital evidence by comparing the original video files and tampering video files resulting from attack frame addition and attack frame delection. The media info tool is used to analyze the metadata and the localization tampering method is used to detect the frame where manipulation occurs. Localization tampering analyzes frame by frame, calculates as histogram and displays a histogram graph. Based on the results of the metadata analysis of the original video file and the video file tampering, it displays different information, which means that the video has been manipulated. Next, analyze the video with the localization tampering method to display the location on the video frame where manipulation has occurred. From the analysis results provide different information both from the calculation of the RGB value and the histogram graph.

Abstract

Conventional crimes recorded on CCTV (Closed Circuit Television) cameras are increasing, every criminal who is proven to have committed a certain crime will be punished in accordance with statutory regulations. The problem is how a case recorded on a CCTV camera can be used as digital evidence. Digital evidence is closely related to ensuring data security, privacy and integrity while following the stages of the digital forensic identification process. The identification stage using the NIST (National Institute of Standard Technolog) method is used for investigations in finding information related to metadata on CCTV camera footage so that it can provide structured information, describe and process information obtained from digital forensic investigation sources that can be implemented into the Chain of Custody document which aims to be used as legal digital evidence in court

Abstract

Solid State Drive (SSD) is the latest solution to speed up data processing from various multiplatform desktop computers. The TRIM features on SSDs has contribute for eliminating garbage data which is permanently deleted by users, where this method has the benefit of extending the service life of SSD devices. Contradiction of implement this method is obstacle potential for forensic investigators to recover deleted data in term of cyber crime in the case of evidence in the form of computers with SSD storage. The experimental object in this study is based on the perspective of mainstream operating systems, namely Windows, Linux and Macintosh installed on the SSD where each operating system simulates the deletion of stored data with a comparison of TRIM enable and TRIM disabled configurations. National Institute of Justice (NIJ) Digital Forensic method implemented in this case, because this method serves as a reference in the practice of Digital Forensics in this study. The SLEUTH KIT Autopsy software is a Digital Forensic tool being used in the perspective of investigators in the acquisition and analysis of SSD evidence in the case simulation of this study. Novelti obtained from the research content is that the operating system which is the object of experimentation is the latest release of Windows, Linux and Macintosh operating systems which certainly has great potential in terms of exploration, especially Digital Forensics. Windows has the greatest chance of recovery results among the other 2 operating systems in this study.

Abstract

The management of citations and reference articles from various scientific journals must be mastered by students in order to produce good scientific works. One of the tools that can be used in managing scientific work citations is the Mendeley tool. The Mendeley tool provides a lot of convenience in improving the quality of writing scientific articles, namely making it easier for students to make citations and bibliography. This training is held at the Universitas Islam Indragiri (UNISI) by involving students who will carry out final research (scripts).

Abstract

Stroke merupakan penyakit yang berpotensi menyebabkan kelumpuhan bahkan kematian. Pada tahun 2022, stroke terdapat 12,2 juta kasus stroke baru yang menambah jumlah total penderita stroke sebesar 101,4 juta. Dari perolehan data maka diperlukan sebuah teknik yang mampu melakukan deteksi pada penyakit tersebut untuk membantu dalam mendeteksi penyakit stroke, dalam hal ini pendekatan machine learning sebagai salah satu solusi yang dapat digunakan untuk melakukan deteksi pada penyakit stroke. Namun sayangnya data yang diperoleh dalam mendeteki penyakit stroke ditemukan adanya imbalance class dalam menangani tidak imbangnya class sehingga dapat mempengaruhi hasil nilai akurasi dalam mendekteksi penyakit stroke, untuk itu dibutuhkan sebuah algoritma random forest dan metode SMOTE dalam menangani imbalance class. Output yang dihasilkan ialah berupa nilai akurasi, presisi, recall, dan f1-score pada algoritma random forest tanpa SMOTE sebesar 0.98, 0.69, 0.51, dan 0.51. Sedangkan algoritma random forest dengan SMOTE mendapatkan masing-masing sebesar 0.91, 0.92, 0.91, 0.91. Terjadi kenaikan signifikan pada presisi, recall, dan f1-score.
