Abstract

The development of technology is currently developing very quickly, this is directly proportional to releasing cyber crime. One crime that often occurs is the case of Pornography. This application is done using one of the very popular Instant Messenger (IM) applications, the WhatsApp application. But after the crime is committed next or sending evidence in the form of conversations, video recordings, images and others committed by the suspect using the WhatsApp application. Therefore, this study proposes to find evidence related to digital pornography. This research produced a forensic procedure in conducting an investigation of the WhatsApp application to obtain previously published evidence containing a conversation session, a list of contact numbers, a profile photo of the victim and others. This research was conducted by reading a backup file of the encrypted WhatsApp application database that stores the conversation session that has been released. This research uses the method (National Institute of Standards and Technology (NIST). This digital evidence can be obtained using one of the forensic tools namely WhtasApp Viewer. The results obtained in this study contain WhatsApp contents that have been available which can be found digitally in uncovering the crime of pornography that is happen.

Abstract

Southeast Aceh Regency is one of the hazelnut-producing areas that produces large amounts of shell waste. This study aims to utilize hazelnut shell ash as a replacement filler in the Asphalt Concrete – Wearing Course (AC-WC) mixture with variations in 2%, 3%, and 4% levels, as well as an optimal asphalt content of 6.4%. The test was carried out using the Marshall Test method referring to the 2018 General Specification of Bina Marga to assess the parameters of stability, flow, Void in Mix (VIM), Void in Mineral Aggregate (VMA), Void Filled with Bitumen (VFB), and Marshall Quotient (MQ). The results of the study showed that all parameters met the specification limits of Bina Marga 2018. The stability value increased with the addition of filler content, from 1464.00 kg (2%) to 1749.67 kg (4%). The flow value is in the range of 2–4 mm, VIM is in the range of 3–5%, VMA is above 14%, and VFB is above 65%. Although the MQ value decreases with increasing filler levels, all values remain above the minimum standard. In conclusion, hazelnut shell ash is effectively used as an alternative filler that is able to improve the technical performance of the AC-WC mixture while providing environmental benefits through the use of organic waste
