Focusing on the most active volcano Merapi, the role of ICT is crucial for improving the security and safety of the surrounding population. Wireless Sensor Network (WSN) which has the capability of monitoring remote and rural areas could be a solution to the early detection of local volcanic activity. Focusing on the most active volcano Merapi, the role of ICT is crucial for improving the security...
In the Wireless Sensor and Actuator Network (WSAN) system, a sensor node must have the function to turn on the actuator in order to move or control an equipment besides monitoring the measured parameter. With the addition function to control the actuator, the WSAN system will have a form of closed loop system. This paper propose a WSAN system in which the sensor nodes and actuator nodes are combined...
Data logger is a key component in building a telemetry system. Using the telemetry system, the activity measurements of an object and retrieval of measurement data can be done remotely (remote). Universal Data Logger (UniDalog), the data logger is a device that has ability to store measurement data, download the data remotely, as well as setting of data logger and remote sensor calibration. By utilizing...
Most of people likes living independently at home. Some activity in our daily life is prone to have some accidents, such as falls. Falls can make people in fatal conditions, even death. A prototype of fall detection system using accelerometer and gyroscope based on smartphone is presented in this paper. Accelerometer and gyroscope sensors are embedded in smartphone to get the result of fall detection...
In this paper, we report our experiment about wavelet decomposition for study environmental condition based on infrared images. Infrared images acquired by consumer digital camera, after replacing the infrared stoping filter with filter SRS, and the images captured sequentially every two hours (from 06:00–16:00). The result of this research is the increasing air pollution characterized using wavelet...
The paper proposes an ozone generation generated by double dielectric barrier discharge chamber which is operated at atmospheric pressure discharge and supplied by high frequency power converter. The air fed or oxygen is bombarded inside chamber that is constructed by a planar type chamber using double aluminum mesh on a metal plate and a double mica sheet as dielectric material. The power converter...
Today, Transformer monitoring is urgently needed. This come from the reality that Indonesian Electrical Company could not know the condition of the transformer which was installed. The transformer is known damaged after something happen with the transformer. The Indonesian electrical company does some maintenance for the transformer, but this maintenance is only for checking the transformer is working...
