Abstract

Now the development of smart phone technology has evolved rapid, especially Smartphone Android. Where multiple sensors embedded in a mobile phone, primarily an accelerometer sensor support be used of smartphone phone. Accelerometer is used to measure the acceleration reviews Angle X, Y and Z smartphone. So that the sensor is used to review the Movement Robot Arm matching is done with corner acceleration motion X, Y and Z smartphone Method on the system is backed with Fuzzy Logic the which serves to Determine the movement of the robot arm that is sent to the microcontroller. Arm robot system is processed using Matlab 6.1 and using the Software Arduino, and then implanted into the microcontroller, so that the robot goes According movement. Keywords : Android, Accelerometer, Robot Arm, Fuzzy Logic

Abstract

Air mancur banyak digunakan untuk memperindah suatu tempat agar tempat tersebut lebih menarik, pancaran air mancur yang banyak digunakan di taman-taman tidak bervariasi sehingga hiasan taman dalam kurun waktu yang lama akan membuat tempat tersebut kurang menarik. Oleh karena itu dibutuhkan suatu alat pengontrol bentuk semburan pada air mancur,dengan pola semburan air bervariasi sesuai dengan irama music yang bervariasi sehingga lebih atraktif dan menarik serta sewaktu waktu bisa diubah sesuai yang diinginkan. Music hanya mengiri air mancur bukan mengikuti air mancur. Air mancur dapat dibuat bergerak mengikuti pola-pola yang telah ditentukan. pola-pola tersebut tidak selalu sama dan akan selalu berubah setiap saatnya. Agar air mancur dapat bergerak sesuai dengan pola-pola yang diinginkan, pengerak berupa motor ditambahkan pada penyemburan air mancur, sehingga pergerakkan air mancur lebih dinamis.

Abstract

Fingerprint recognition system aims to identify someone. The main obstacle in recognizing a person's fingerprints is that the image has a low quality. The quality is caused by the type of oily, dry, dirty skin and the type of fingerprint scanner used. For this reason, an increase was made with the aim of improving fingerprint images as the main factor determining the level of accuracy of fingerprint image recognition results. In order for fingerprint images to be easily interpreted by humans and machines, it is necessary to improve quality by clarifying the fingerprint line. This study aims to improve the quality of fingerprint images with the Minutiae Extraction algorithm and the Learning Vector Quantization (LVQ) method as a test. This test is carried out using 4 images as training in each class. The total number of classes in this test is 10 classes with each class consisting of 10 images. In testing 75 fingerprint image data obtained an accuracy rate of 83.3333%.
