Abstract

Stellarium merupakan software simulasi gambar 3D yang dapat menampilkan benda-benda angkasa secara detail, sehingga pengamat astronomi dapat mengetahui koordinat suatu objek angkasa melalui data yang disajikan oleh stellarium. Akan tetapi pencarian objek berdasarkan koordinatnya jika dilakukan pengamatan secara manual menggunakan teleskop akan membutuhkan waktu yang cukup lama. Oleh karena itu diperlukan suatu sistem yang secara otomatis dapat menggerakkan teleskop berdasarkan data-data yang diperoleh melalui stellarium. Sistem tersebut dapat dibangun dengan mengintegrasikan arduino, kamera, sensor potensiometer, motor servo dan motor dc. Stellarium mengirimkan data ke komputer berupa koordinat objek. Kemudian di komputer koordinat tersebut dikonversi dalam bentuk derajat dan dikirim ke arduino. Dengan metode fuzzy logic arduino akan menggerakkan motor dc menuju objek berdasarkan data derajat dan sensor potensiometer. Kamera akan menangkap gambar real-time melalui teleskop dan ditampilkan ke layar monitor komputer. Kemudian komputer melakukan image processing yaitu autofocus dengan motor servo untuk memperjelas gambar dan tracking dengan menentukan titik tengah objek. Saat benda bergerak, kamera akan meng-update koordinat objek dan menggerakkan teleskop menuju koordinat baru objek tersebut. Berdasarkan pengujian, kesalahan hasil konversi sensor derajat azimuth rata-rata sebesar 0.6 derajat, sedangkan untuk altitude rata-rata sebesar 0.6 derajat ==================================================================================================== Stellarium is a simulation software that can display 3D images of celestial bodies in detail, so that observers can determine astronomical coordinates of a celestial object through the data presented by Stellarium. However, if object searching is observed manually, it will require considerable time. Therefore we need a system that can automatically move the telescope based on data obtained through Stellarium. The system can be constructed by integrating arduino, camera, potentiometer sensors, servo motors and dc motors. Stellarium transmit data to a computer in the form of the object coordinates. Then in the computer, coordinate is converted in the form of degrees and sent to arduino. By using fuzzy logic method, arduino will drive the dc motor toward the object based on the degrees data and potentiometer sensor. The camera will capture real-time images through the telescope and show it to a computer screen. Then the computer perform image processing that is autofocus with servo motors to clarify the picture and tracking by determining the midpoint of the object. When the object is moving, the camera will update the coordinates of the object and move the telescope to the new coordinates of the object. Based on testing, fault degrees azimuth sensor conversion results by an average of 0.6 degrees, while the altitude by an average of 0.6 degrees
