Abstract

Badan Kepegawaian Negara is a government agency that has the task of carrying out governmental tasks in the field of state staff management. Badan Kepegawaian Negara accommodates students who want to do an internship. There were several obstacles in organizing internship activities, namely the internship registration that requires the internship candidate to come to the office of Badan Kepegawaian Negara, the recapitulation of the internship students that were separated, and monitoring the daily activities of the internship students that were difficult. The problems existed in the internship activities could hamper the administrative processes of internship students, so this research aimed to build an internship information system that could help the administrative processes. The internship information system development used waterfall approach. In this research, the problem related to administration processes of the internship students can be made easier by adding, eliminating, or changing the current business process (as-is) to a proposed business process (to-be) to produce features in the internship information system that was built with the laravel framework. The internship information system that has been build was then tested using the user acceptance test approach to measure the level of user acceptance of the internship information system features, the flow of activity on the internship information system, and the interface of the internship information system. The results of the user acceptance test showed the number 92,39% which showed the user accepted the information system and the features inside the system.

Abstract

Wireless Sensor Network (WSN) technology becomes a popular technology these days and it even becomes one of the most promising Internet of Things (IoT) applications. Heterogeneous network sensors are needed for integrated sensing systems. Universal Plug and Play (UPnP) is one of the most promising technologies that enable network and service deployments. The UPnP protocol was previously successfully implemented on IP-based Smart Home devices that function for device and service recognition through the UPnP discovery and description stages. This research creates a gateway on non-IP-based wireless sensor nodes which implements the search and recognition system of sensor nodes using the concept of the UPnP protocol to recognize sensor nodes so that interoperability in WSN can be improved. There are two tests conducted, namely functional testing and system performance testing with several scenarios. In functional testing, the system can perform discovery, addressing, and description. Performance testing is measured when the system performs the discovery and data transmission by using delay parameter and success ratio with a total of 10 tests with several variations of distance. The results of the total average delay discovery tests with distance of 5m, 30m, 60m, 90m and 100m are 6,195s, 50,845s, 29,549s, 21,605s and 26,534s with total success ratio of 100%, 98%, 98 %, 90% and 83%. The results of the total average delay of sending data with distance of 5m, 30m, 60m, 90m and 100m in sequence are 0.959s, 2,231s, 3,807s, 3,480s and 3,713s with total success ratio of 95%, 85%, 88%, 95% and 95%.

Abstract

Software-Defined Networking (SDN) is a new concept on network computers. By seperating the data plane and the control plane, logics and algorithms for managing networks are placed on a controller. Currently, an algorithm that is being used for finding a shortest path on SDN networks is Diijkstra's algorithm. However, Dijkstra's algorithm has its downside, that is doesn't count bandwidth overhead. As a result, network congestion will occur if the packet size that is being send, is bigger than the available bandwidth. Therefore, the modification of Dijkstra's algorithm is needed. Dijkstra's algorithm is modified with available bandwidth as its cost. When searching a path, the algorithm will find a path which has a bigger avalaible bandwidth. There are three tests on topology A and B, that is finding a path 1 test, finding a path 2 test, and time convergence test. Finding a path 1 test is conducted when there is no traffic and changes of bandwidth on networks. Finding a path 2 test is conducted when there is traffic and changes of bandwidth on networks. Time convergence test is conducted by counting how much time that the algorithm needs to find a path 1 and 2 on each topology. When finding a path 1 and 2 tests, Dijkstra's algorithm succeed for finding a path based on bandwidth. For time convergence test, the algorithm works better on topology A when finding a path 1 and 2. The average time is 8.2 seconds and 13.1 seconds. However on topology B, finding a path 1 and 2 takes an average time about 93 seconds and 114.8 seconds.
