Handwritten Alphabet Recognition is one of the artificial intelligence applications which provides animportant fundamental for various advanced applications, including information retrieval and human-computerinteraction applications. This paper elaborates a research which is performed to build a system which is able torecognize handwritten latin alphabets in the form of images. The system is developed using the HammingNetwork method.From the experiments of 100 prototypes of data, the system is able to identify handwritten latin alphabetswith 76.97% average accuracy. Mistaken recognitions are mainly caused by the similarity of the alphabetpatterns, such as the pattern of I, T and Z, or the pattern of C and G. The value of ε and the matrix b which aregiven in the system may affect the recognition results.Keywords: Handwritten Alphabet Recognition, Hamming Network

Shape recognition is important in digitizing information era. It enables computer system to recognize someshapes. The shape could be a picture or a handwriting letter. There are many methods can be applied to do so.This paper presents on how n-tuple method and fuzzy logic sistems can also be implemented. The shapes can be recognized by the system are limited to capital letter from A to E, and some plane geometriessuch as square, circle, triangle, hexagon, and rhomboid. The image input is a binary image and processedthrough n-tuple method. Tsukamoto method is used for fuzzy inferencing. The inputs in this fuzzy system aretaken from the output of n-tuple method.During the experiments, the system had been trained by 10 data samples for each shape, and then tested by 20data for each shapes. From the experiments, capital letter ‘E’ can be recognized 100% correctly. On the otherhand, the least correctly recognized is shape hexagon which is only 60%.Keywords : Shape Recognition, N-tuple Method, Fuzzy Logic

Abstract— An automatic parking system miniature modeldesign and implementation is reported in this paper. The systemis a minimum based system using Near Field Communication(NFC) technology, and connected to a database server. Thesystem can be divided into two subsystems, namely a decision andcontrol system, and database server system. Furthermore, thedecision and control system can be divided into two elements: (i)Element 1 which consists of LCD module, NFC module, andEthernet module, and (ii) Element 2 which consists of LCDmodule and stepper motor driver module. The two elements areconnected through a wireless connection using XBee wirelessdevice. To implement the NFC feature, NFC Shield V2.0manufactured by Seed Studio is used. As an initial process, allNFC tags and cards are registered to the database server system.Then the parking process is starting with the detection of NFCtags or cards in Element 1 of the decision and control system.Based on the detection results and the results of querying thedatabase server a decision is then send to Element 2 that willmove the lift to the designated parking lot. In that sense, thesystem is able to allocate the parking space to its users who havethe registered card or tag. Freetronics EtherMega v3.0 is used asthe central processing unit for the system which is used forquerying the database and take actions based on that queryresults. An integrated Ethernet chip on EtherMega is used toconnect the decision and control system to the database serversystem, because the system can connect directly to the databaseserver. A computer that is usually needed to be the middle manfor procession queries is no longer needed. From a number oftests performed, the system works well and can achieve 100%allocation success rate. The system is able to allocate the parkinglot very well and to check whether the lot is occupied or free. Thesystem can also control the lift to move to the appropriate lot.Observed weakness is that the system’s stability is affected byheat generated by the system itself.Keywords—wireless, database, automatic parking, feedforward,RFID

Fuel shortage is a common problem in Indonesia. This prompted many cases of vehicle fuel theft. As a solution to this problem, an Arduino-based vehicle fuel theft detector system is implemented. Arduino-based vehicle fuel theft detector system is a prototype that uses Arduino UNO as a microcontroller, IComSat v1.1 SIM900 GSM/GPRS Shield to communicate with mobile phone, fuel level sensor as a volume detector, and push button as a detector to check whether the fuel tank’s lid is open or closed. The working principle of this system is to detect the state of the fuel tank lid. When the lid is open, the system will make a phone call. Then, the system will keep track of fuel volume. If there is a drastic decrease in volume, the system will send information about the decreasing volume in the form of a short message to the owner of the vehicle. The success rate of the communication system between Arduino UNO and other electronic devices is 100%. Accuracy of fuel level sensor is 90%. Success rate of push button switch in detecting the state of fuel tank’s lid is 100%. Success rate of GSM Shield communication is 90%.

The purpose of Hoare Logic is to provide a set of logical rules in order to reason about the correctness of computer programs with the rigor of mathematical logic. Because of that, Hoare Logic becomes the axiomatic basis for computer programming with several rules to prove the correctness of program. Hence, we can apply the proven rules of Hoare Logic as the basis to design a program correctly according to Hoare Logic. In this paper, Hoare Logic is applied in a software which is designed to help the user to design a program in C programming language correctly based on rules in Hoare Logic. When using this software, the user needs to know what program he will create and analyze an algorithm for it. After that, the user can use the software containing the rules of Hoare Logic and write the pseudo-code of C to design his program. At the end of this application, the user will obtain a source code of the program written in C programming language. This software is guaranteed to produce 100% correct output only if the users have the basic understanding of Hoare Logic as well as C program language before using this software.

According to how soccer robot movement is controlled, approaches in soccer robot can be divided into two categories, namely centralized and decentralized. Centralized approach is an example of control over network concept where devices are controlled over the network. Each robot obtains information from a vision system outside the robot to detect the ball, and the central computer makes decision on which robot to approach and kick the ball. Wireless communication between robot and central computer must be reliable. One of the most important components in soccer robot is the ball kicking mechanism, which has to be able to kick the ball accurately. The wireless communication system is developed with a WeMos D1 microcontroller. Ball kicking mechanism is developed using solenoid circuit controlled by the microcontroller. Testing showed that wireless communication system has 100% reliability when operated in range up to 300cm. The ball kicking mechanism was able to respond accurately to ball kicking command when the robot is stationary and moving. When the robot is stationary, average kicking distance of the ball is 42.22cm and average tilt angle is 29.58°. When robot is moving, average kicking distance is 40.98cm and average tilt angle is 26.12°.
