Synchronization of learning management systems with store-and-forward communication using ship to support e-Learning at rural islands. Alwin Melkie Sambul, Agustinus Jacobus, Alan Riyaldi Universitas Sam Ratulangi Abstract One of the challenges for the people who live in the rural islands of the developing countries is the lack of access to education. Although ICT (Information and Communication Technology) is increasingly regarded as an essential tool to support learning activities in rural areas, the availability of telecommunication infrastructure in such areas is still problematic, primarily because of high implementation cost and low revenue. This study aimed to develop an e-Learning model for the community in the rural islands which utilize ship to deliver to and receive data from the island using store-and-forward communication technique over a transient long-range wireless link established when the ship is at a certain distance from the island. Here we focused on the design of a synchronization method between databases of multiple learning management systems (LMS) between the ship and the island. The design has been implemented and tested using Moodle installed on low-power Raspberry Pi computers. The result showed that our design is suitable to be used in such requirements, hence making it a feasible solution to support ICT-based learning for the people in rural islands.

As far as we know that physics experiments wich conducted in well-equipped laboratories, improve students science process skills (Hirca:2012). It is hard to imagine learning to do science, or learning about science, without doing laboratory or fieldwork (Trumper:2003). But many schools in various part of the world have very poor or no laboratories, so the teachers have to use their own equipment and replace the students experimental work with simple demonstration experiments (Ozvoldova, Spilakova, Tkac). The purpose of this study was to create physics learning media for archimedes law using simulation to cover the lack of the availability of laboratories and physics paracticum tools.

Wireless Sensor Network (WSN) is the solution for a monitoring technology. However, not all monitoring must be continuous, there are some monitoring that can be carried out periodically. Therefore it is possible to invent a mobile sensor communication system on multicell networks. This research aims to implement a WSN system by collecting data from mobile sensors on multicell networks. The focus of research is on the design of mobile sensor communication with low-cost device as transceivers, namely NodeMCU. The design is implemented using 4 NodeMCU units, 3 of them are functioned as access points, while 1 unit is employed as a client connected to the sensor. The experimentation was conducted by varying transmission distances of sensors with and without barriers. Moreover, handover and blankspot areas are also included accordingly. The result of experimentation shows that the usage of low-cost devices has still possibility to built monitoring mechanism on multicell networks eventhough the transmission power was significantly influenced by the availability of barriers.

STUDY OF ELECTRIC POWER SYSTEM OSCILLATION DAMPING 1Daryanto, 2M. Rifan, 3Purwanto Gendroyono Electrical Engineering Education Study Program, Faculty of Engineering, Jakarta State University, Jakarta, Indonesia Abstract Delivery of electrical power from the power plant to the load center of widespread done through transmission networks with limited capacity. The operation of such an electric power system can cause a stable condition to be disturbed and a worse result is a total blackout. This study aims to investigate the influence of dynamic loads on the electric power system oscillation damping. The behavior of the electric power system after disruption studied to determine the effect of parameter changes the dynamic load of the electric power system oscillation damping. The electric power system model in this study is a dynamic load model and synchronous generator model. Dynamic load models are developed from the Hill model based on load power responses due to voltage changes. The mathematical formula that describes the interaction between voltage and load power is realized by first-order differential equations. While the electric power system model is based on a model developed by Demello, which is a single electric generator connected to an infinite bus. The synchronous machine in this model is obtained from the classical Park model by assuming that (1) the condition is balanced, (2) the stator coil resistance is ignored, (3) the influence of saturation is ignored, (4) the transmission network is assumed to be zero, and (5) the local load is assumed the voltage depends only on the real power. Based on the two models, an overall block diagram is made that illustrates the interaction between dynamic loads and the electric power system. The results showed that there was an increase in the stability of the electric power system with dynamic load feedback and a decrease in the rotor angle and increase in voltage. So that it can be concluded that changes in dynamic load parameters affect the stability of the electric power system. Keywords: Keywords: damping, oscillation, dynamic load parameters, electrical power system, synchronous generators. PermaLink | Plain Format | Corresponding Author (Daryanto, M.T. -)
