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

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

Social media is an alternative means of communication on smartphones, as many as 28% of the WeChat instant messenger application is used as a social interaction for the delivery of messages by senders and recipients, Cyberbullying on the WeChat application results in intimidation by users, so to deal with the crime of Cyberbullying applications WeChat on Smartphones requires a Mobile Forensic technique to identify digital evidence of verbal conversations on the WeChat ap-plication using the Framework In- tegrated Digital Forensics Process Model (IDFPM) method based on SNI 27037: 2014 which is carried out on Smartphones. WeChat application which was previously encrypted and hashing values of md5 and sha1 are authentic, as well as metadata or timestamp in the WeChat application conversation mes- sages using the Mobileedit Forensic Express Tools, and successfully implemented Frame Work Inte- grated Digital Forensic Process Model (IDFPM) based on SNI 27037: 2014 on the forensic investiga- tion process using Android Smartphone media.

Abstract

Penyakit jantung merupakan penyakit paling mematikan didunia. Laporan WHO tahun 2019 menyebutkan penyakit jantung sebagai penyebab kematian tertinggi didunia dengan persentase 16% dari jumlah kematian atau 8.9 juta kematian. Tingginya kematian yang disebabkan oleh penyakit ini terjadi karena penyakit ini biasanya timbul tanpa adanya gejala sehingga sulit untuk diketahui sejak dini oleh penderita. Salah satu cara untuk mengatasi permasalahan tersebut adalah dengan pemanfaatan metode klasifikasi. Hasil klasifikasi multi-class pada penelitian sebelumnya dengan dataset dan metode yang sama masih terbilang rendah yang salah satunya disebabkan oleh adanya imbalace data. Untuk itu dibutuhkan teknik balancing data serta feature selection (FS) untuk melihat pengaruh imbalance data dan pengaruh korelasi fitur pada klasifikasi multi-class. Pada penelitian ini menggunakan Synthetic Minority Over-sampling Technique (SMOTE) untuk balancing data dan Pearson’s Correlation (PS) untuk memilih fitur dengan korelasi yang baik pada klasifikasi penyakit jantung menggunakan metode Multi-Layer Perceptron (MLP). Penelitian ini dengan MLP+Pearson’s Correlation hanya mendapatkan akurasi tertinggi sebesar 63.33%. Akurasi tertinggi dengan penggabungan metode MLP+SMOTE+Pearson’s Correlation sebesar 92.5%. Serta akurasi tertinggi pada penelitian ini didapat menggunakan metode MLP+SMOTE yaitu sebesar 97.5%.

Abstract

Interactions in social media can be seen from comments as feedback from every activity on social media, starting from statuses in the form of text, images or videos. One area of computer technology that can study the meaning of text is text mining. Sentiment analysis or opinion mining is a solution to solving problems to automatically classify opinions into positive and negative. Comments from YouTube video viewers on the TvOne channel about Ustadz Abdul Somad being deported from Singapore. From the various responses in the comment column, information is obtained from unstructured data, so there is a needfor a technique to define the value of information. The focus in this research is to verify the truth and explore the value of structured information so that itcan describe events and topics that are connected from the comments in the YouTube videos which are the object of this research. From the test results above, it can be seen that the performance values from the test results using the Support Vector Machine method get 95.02% Accuracy, 95.02% Recall, 95.18% Precision and 95.01% F1-Score.

Abstract

One of the solutions used for access speeds is to maximize non-volatile storage functions by a conventional Hard Disk Driver with Solid State Drive that has the TRIM architecture using the Redundant Array of Inexpensive Disks 0 configuration or the commonly known RAID 0. RAID 0 is a stripping technique that has the highest speed among other RAID configurations. However, this configuration has a disadvantage in that when there is damage to one of the storage disks all the data will be corrupted and lost. It's becoming one of the challenges in digital forensic investigation when it comes to computer crime. Furthermore, this research uses experimental practices using live forensic methods to perform analysis and examination against the merger of HDD and SSD configuration RAID 0 TRIM features. The expected is an overview of the characteristics of recovery capability to find out the authenticity integrity values of files that have been lost or permanently deleted on both TRIM SSD functions disable and enable. Furthermore, this research is expected to be a solution for the experimental and practical investigation of computer crime especially in Indonesia given the increasing development of technology that is directly compared with the rise in computer crime.
