Development Of Automatic Traffic Light Based On Wireless Sensor Networks With Star Topologies

Traffic jam at the intersection is caused by many things such as the number of vehicles that exceed the capacity of the highway, road users who do not obey the rules, or lights on a traffic light that is not in accordance with the road conditions. The government has implemented measures to control congestion solutif at a crossroads in Indonesia, especially in big cities by installing the ATCS (Automatic Traffic Control System) that regulate light traffic lights based on real time conditions crossroads. The weakness of this system still needed the operator to settings the traffic light lamp replacement and maintenance costs are expensive. Therefore, we need a system that can regulate light traffic lights adaptively based on the length of the queue of vehicles. In this project, created a system that is able to set the lights on the traffic light by the long queues of vehicles adaptively based wireless sensor networks. Data from XBee sent with a frequency of 2, 4 Ghz towards the coordinator node, the coordinator node data is then processed by a microcontroller arduino mega to compare the length of the queue between the road and determine the traffic light lights adaptively. The test results show a sensor capable of detecting the vehicle up to a distance of 175 cm, the system can detect the length of the queue as far as 56 meters, and can be changed adaptively in a ccordance long queues of vehicle.

Batik Originality Marker As a Protection Model To The Manufacturer And Batik's Consumer

Such way from Pekalongan City Government in protecting the existence of crafstmen/batik seller and its consumer is by publishing region regulation of Pekalongan City Number 6 in year 2014. By that regulation, Pekalongan city government obligue all manufacturer/batik seller that produce and sell batik product in/from Pekalongan city should label their product with “ Batik Pekalongan”, hence it is not only functioned as a marker for consumer that is not able to identify the kinds of batik nor differentiate with printing batik, but also functioned as a protection model for the manufacturer/batik seller in Pekalongan. Nevertheless the absence of monitoring in the usage of label “Batik Pekalongan”, has been absorbed by certain manufacturer/batik seller to make fraud, thus the effort of Pekalongan city governmnt in giving protection to the manufacturer/batik seller and also their consumer hasn’t been well realized. The research resulted an e-label batik application that supports the effort of Pekalongan city government, by augmented reality technology utilization will make the label of “Batik Pekalongan” displaying such information about the kinds of batik, batik pattern/motif, the profile of the manufacturer/batik seller and other related information, if consumer scans that label by their smartphone, the information will be just displayed, and when the Pekalongan city government as the observer of the usage of batik label has done the validation based on the sustainability of the label certainty with the kinds of batik sold by the manufacturer/seller, the label of “Batik Pekalongan” will be functioned as the trusted mark
