Abstract

Every year, the number of vehicles is increasing due to the development of the population, economy and improvement in living standard. Although there are parking lots, there are still many drivers who park their vehiclesin places where they can disrupt the smooth flow of traffic. The application of a parking reporting system uses the Google Maps API to mark areas and get coordinates for reporting illegal parking. The process of marking the parking ban area uses the polygon method with the number of roads as test data as many as 14 street names, 25 parking ban areas and 100 coordinate points (latitude, longitude). Every report on illegal parking has images and coordinates of location reporting that will automatically be validated by the system. The validation process by the system uses the JavaScript API Geometry library to get the results of whether a reported vehicle is in the parking ban area. Of the 12 coordinate points randomly placed with 6 positions insidethe parking ban area and 6 outside the parking ban area, the system is ableto validate the data correctly.

Abstract

Abstract— Literally embedded systems are defined as equipment that computes a particular job. Embedded Linux System was also developed as a means of education, one of which is ED-255EK Embedded Education Platform, designed to be very practical and consume very low power. ED-255EK is also equipped with a PXA255 processor that is compatible with ARM version 5TE ISA, so it can be used to carry out various kinds of lab work or experiments on embedded systems. The working principle of this tool begins with the configuration of data communication between Fedora Linux and ED-255EK. When the communication goes well, it is downloaded by the ED-255EK system to a laptop or computer that has been installed with the Fedora 9.0 Linux operating system. To take advantage of the ED-255FPGA module, driver module installation is required first, after which the application program is installed. Laptops or computers that have installed the Fedora 9.0 Linux operating system will act as input and output programs making it easier to monitor each module that is being run. The module used is the ARM 1923 Robot Module and Voice Module ED4321.

Abstract

One of the facilities provided by cellular phones is to send data in the form of short messages via Short Message Service (SMS). Most people use SMS services more often than phone services because they are cheap and easy to use. Open networks, easy access, standard platform and open source development bring security threats such as viruses, phishing, spam on SMS. Security information in SMS can be done by encrypting messages to be sent. The AES (Advanced Encryption Standard) algorithm is a standard for data encryption, suitable for scenarios where memory and processing capabilities are very limited as in mobile devices. Encryption for text data types can also use the Blowfish algorithm, where the Blowfish algorithm can perform encryption and decryption with better performance compared to other symmetric algorithms if packet data size changes. Research designing systems that can be utilized by users who want to send a confidential information to someone via SMS without fear of information from the message will be known by others. The method used by the system in encrypt and decrypt the message is AES method and Blowfish Cipher which implementation using java programming language on Android.

Menjangan feeder is a medium-voltage network system which distributes electricity throughout Gilimanuk and some areas in Buleleng. It has 69 distribution substations, which one of them, substation GR088, contributes to the highest value of the total harmonic distortion (THDi). In this research, the effect of harmonic distortions on losses at low voltage system of substation GR088 will be evaluated. The method used in this study is direct measurement of harmonic distortions at each low-voltage costumer whose electricity is generated by substation GR088 at Menjangan Feeder. Software is also used to perform harmonic load flow analysis and simulations. The total value of losses on transformer and low voltage system of substation GR088 Menjangan feeder, in a no-harmonic condition is 1481,689 Watt. On under-harmonic condition, the total value of losses is 1552,5 Watt. Therefore there is a 70,811 Watt difference between the two conditions. At this case, beside the heat created by the harmonic distortion that can affect the performance of transformers, it also cause a quite great value of losses, which is 1,699 kWh per day, or approximately 620 kWh per year. It means the harmonic distortion in substation GR088 can cause PT PLN (Persero) lose Rp.910.018,79 per year.
