With the advancement of technology and on the basis of the need for transaction management, data management, and information delivery, it is necessary to create a web-based camping and hiking equipment rental application at Pandanaran Outdoor, this website is designed using CodeIgniter, PHP, Visualcode, Bootstrap, Javascript, and MySQL Database. The system method used in this research is the waterfall method, the results obtained are used to describe the sequence of software development processes as a cycle in the flow of making rental applications. The presence of this application is expected to speed up and simplify the process of renting camping and hiking equipment at Pandanaran Outdoor.

Interior is the arrangement of the inner room with the aim of meet the needs of the facility, namely the element of functionality and the aesthetic element of beauty. However, not all rooms can implement both elements because of a lack of knowledge about rooms and interiors. Interior design also can’t be done carelessly, especially the bedroom. This is because the bedroom can give an impression which is an important principle for users, namely the level of comfort and type of activity. Therefore, the aim of this research is to provide the visualization of bedroom interior in 3D animation to be a source of reference for users. This research use R&D (Research and Development) method, which use a qualitative approach by interviewing 30 respondents as a research method and by Multimedia Development Life Cycle (MDLC) method as a development method. The result of this research is the visualization of bedroom interior in 3D animation that can be used as a reference source for users to design bedroom interiors.

The current condition of the Karangantu Archipelago Fisheries Port (PPN) is still considered unfavorable because the operational area of ??the port waters looks dirty and shabby. There are many ships that are no longer used in the Karangantu PPN operational area. Based on the results of interviews with PPN Karangantu officers, there are several things that cause ships to be abandoned in the operational area of ??PPN Karangantu waters, including the age of the ship, costs or capital, and human resources. Abandoned ships that are not immediately handled will result in obstacles to the flow of water traffic at the port and create a risk of collision for other ships passing by. Therefore, web-based mapping of abandoned ships (WebGIS) is needed in the operational area of ??PPN Karangantu waters. It is hoped that the results of this abandoned ship mapping can be used by the port to report abandoned ships to the center so that they can immediately take action to transport the abandoned ships. With the existence of WebGIS mapping abandoned ships, the port does not need to go directly to the field to find the location of abandoned ships because the information can be accessed via the web that has been created. Data collection on coordinate points was carried out by field survey and tagging using the GPS Map Camera application. The research results show that there are 74 abandoned ships in the Karangantu PPN operational area.

A Currently, various communication platforms are available, and one of them is Discord. Discord is utilized by users to interact and share various types of content. However, Discord is often implicated in the distribution of inappropriate content that goes against Discord regulations. This can lead to cybercrime cases such as Child Sexual Abuse Material (CSAM). The main challenge faced is the recovery of digitally deleted data through these communication platforms. The objective of this research is to analyze digital evidence in the form of deleted text messages, images, and documents in the chat rooms of the desktop-based Discord application. The research method employed is the Live Forensic Technique, applying the DFRWS (Digital Forensics Research Workshop) method. The digital forensic analysis process is conducted using the digital forensic tool Magnet Axiom. The research results indicate that the accuracy of digital evidence analysis using Magnet Axiom reaches 94.11%. A total of 16 digital evidence items were successfully recovered out of the total 17 items available

Securing image files is a crucial aspect in addressing information security challenges. Super encryption is an approach that combines various cryptographic algorithms to enhance data security. In this research, we implement Super Encryption by combining two algorithms, namely Route Cipher and VMPC (Variably Modified Permutation Composition). Firstly, we employ the Route Cipher to encrypt image files by rearranging the pixels in the image using a specific mapping scheme. Subsequently, we apply VMPC, a key-symmetric encryption algorithm, to encrypt the previously modified image. The use of VMPC as the second layer aims to provide additional security by incorporating efficient and secure key-symmetric encryption. The results of this research demonstrate that the combination of Route Cipher and VMPC provides strong security for image files. This method introduces a high level of complexity for attackers attempting to decrypt the image without the correct key. Moreover, this Super Encryption offers higher confidentiality and resilience against attacks on image files compared to using a single encryption algorithm.
