Authors: Maulana H , Al-Khowarizmi  
Published: April 2021

Abstract
The development of information and data communication technology field in the world has now increasingly led to the development of the Internet of Things devices. The development of network technology in an organization/university has triggered the need for a system that can monitor computer networks and their devices in an organization/university environment that is quite extensive and complex. At this time, network monitoring becomes quite difficult to do if the computer network in a corporate environment has become very broad and complex. The wider the network and the complex network and multimedia topology that is built, the more difficult it is for network administrators to monitor the network. However, in its application to build a monitoring system it will require devices and hardware and computer requirements and specifications that are above average, which of course will also require substantial costs and large resources as well. In this research, a network monitoring and bandwidth management system will be built by using Raspberry-Pi and Icinga as the main modules in network management. Raspberry Pi is an alternative of computers that has many capabilities and has a high ability which is generally used as a Mini-Server at a very cheap price when compared with existing servers. And Icinga is an open source-based application platform that functions to monitor various types of variables contained in servers and infrastructure of the network such as availability and performance and provides easy access for network administrators to important data and to improve maintenance of network conditions. So, it is hoped that by applying this, a good and optimal network monitoring and bandwidth management tool can be produced at a low cost.

Published: April 2021

Abstract
The PHP programming language is now widely used by agencies and companies around the world. To distribute applications made using PHP must use the source code so that it is prone to theft of works. If the source code is found by the programmer, it will be a big problem because it can indirectly find a hole in the security of a system from the source code. To solve this problem, the source code was coded so that the source code could not be easily copied by other parties. One of the ways to encode the source uses a combination of the Merklee-Hellman Knapsack algorithm, Discrete Logarithm and character modification to obtain complex encryption
