Cybercrime on Internet that keeps increasing does not only take place in the environment that running web applications traditionally under operating system, but also web applications that are running in more advance environment like container service. Docker is a currently popular container service in Linux operating system needs to be secured and implements incident response mechanisme that will investigate web server that was attacked by DDoS in fast, valid, and comprehesive way. This paper discusses the investigation using Grr Rapid Response framework on web server that was attacked by DDoS running in container service on Linux operating system, and the attacker using Windows oprating system that runs DDos script. This research has succesfully investigated digital evidence in the form of log file from web server running on container service and digital evidence through netstat on Windows computer.

An attack on Internet network does not only happened in the web applications that are running natively by a web server under operating system, but also web applications that are running inside container. The currently popular container machines such as Docker is not always secure from Internet attacks which result in disabling servers that are attacked using DoS/DDoS. Therefore, to improve server performance running this web application and provides the application log, DevOps engineer builds advance method by transforming the system into a cluster computers. Currently this method can be easily implemented using Docker Swarm. This research has successfully investigated digital evidence on the log file of containerized web application running on cluster system built by Docker Swarm. This investigation was carried out by using the Grr Rapid Response (GRR) framework.

This paper describes the design and manufacture of an underwater explorer robot. The proposed Mini Remotely Operated Vehicle (ROV) is designed to be controlled remotely using a wireless communication module outside the water. ROV stability is needed to support the operation of ROV when do maneuvering in the water. The design of the ROV is aimed to maintain stability using a PID control system. Moreover, the gain PID values, kP gain, kI gain, and kD gain, must be set to perform roll stability. After performing a fine-tuning of the PID gain values, the experiment result shows that the system can maintain an average error of -1.70 degrees.
