Abstract

Aksara Jawa merupakan ciri khas dan warisan leluhur dari Suku Jawa yang perlu dijaga dan dilestarikan keberadaannya. Penulis mengembangkan perangkat lunak proses segmentasi citra aksara jawa. Tujuan dari dilakukan segmentasi citra adalah mengubah representasi dari suatu citra menjadi sesuatu yang lebih berarti dan mudah untuk dianalisis . Segmentasi citra dengan menggunakan metode clustering dapat digunakan dengan berbagai macam metode, salah satunya adalah Particle Swarm Optimization (PSO). Dalam prosesnya digunakan metode Particle Swarm Optimization (PSO) untuk proses segmentasi pada karakter Aksara Jawa. Untuk mengatasi beban komputasi yang cukup berat pada proses segmentasi citra, maka diterapakan metode parallel programing, dan arsitektur komputer yaitu GPU dengan support CUDA dari NVIDIA. Hasil akhir dari penelitian ini dapat mengimplementasikan segmentasi citra digital dengan metode Particle Swarm Optimization pada Aksara Jawa. GPU CUDA mempercepat proses segmentasi citra Aksara Jawa.

Abstract

In recent years, robots have captured the interest of more and more people. In the entertainment industry , robot has been developed in various style. One of it is robot that have shape and behavior like insect. Based on that reason, writer wants to make a robot that has a unique form. This kind of robot have a creative and imaginative design , of course it is supported by appropriate capability. This robot also have ability to calculate distance and avoid an obstacle that required by robot which works in frequently disturbed path. Range Detector Wire Leg Robot Base on AT89S51 use infrared detector as distance and obstacle detector. As infrared receiver used an infrared module GP1U52X . The range between the obstacle and robot is gotten by measuring the strength of the reflected burst of infrared light. The result of distance measurement is used by microcontroller to decide direction of robot movement. DC motor used to move the robot for DC motor driver used L293D IC’s. The research shows that wire leg robot can detect obstacle distance in front of it based on strength of the infrared reflected burst (near , medium and far distance) . From that detection result, wire leg robot can make movement to avoid the obstacle. Object used as an distance detector reference must not have slippery surface / flat
