Abstract

ELCONAS (Electronic Control with Android System) is a tool designed to control electronic devices. This control Android via Bluetooth communication and SMS Gateway that can be controlled by the user. Control using Bluetooth, applied for a certain distance which is connected to android, Bluetooth with limited distance range of services and the use of the remote system is used SMS Gateway is connected via a short message that is sent to the microcontroller through a module that has been installed on the microcontroller, using ArdunioMega 2560. ELCONAS designed to minimize the occurrence of short circuits and even prevent fires because the user can handle it via the application without having to interact directly with electronic devices that are at home or office.

Abstract

Pendeteksian tepi menjadi salah satu tahapan penting pengolahan citra dalam proses segmentasi karena dapat mempertegas batas-batas antara objek dan latar belakang. Banyaknya metode deteksi tepi saat ini menimbulkan keraguan dalam memilih metode deteksi tepi yang tepat dan sesuai dengan kondisi citra. Berdasarkan masalah tersebut dilakukan penelitian untuk menganalisis kinerja metode deteksi tepi Sobel, Prewitt, Roberts dan Canny menggunakan thresholding Otsu berdasarkan nilai threshold, waktu proses dan pengamatan visual. Program dibuat menggunakan perangkat lunak Microsoft Visual C# 2010 Express. Hasil penelitian terhadap tiga citra uji bahwa metode Canny menghasilkan tepian yang tipis dan halus serta tidak menghilangkan informasi penting pada gambar meskipun membutuhkan waktu komputasi yang tidak sedikit. Nilai threshold yang diperoleh dari Otsu  merupakan nilai ambang terbaik dan optimal untuk setiap metode
