Abstract

Pengamatan objek langit khususnya bulan seringkali terkendala oleh rotasi bumi yang mengharuskan penyesuaian posisi teropong secara manual dan terus-menerus, serta mahalnya harga sistem pelacak otomatis (GoTo Mount) di pasaran. Penelitian ini bertujuan untuk merancang bangun sistem penggerak teropong otomatis yang terjangkau berbasis mikrokontroler Arduino Mega 2560 dan ESP8266 yang terintegrasi dengan data koordinat dari perangkat lunak Stellarium, serta mengimplementasikan Algoritma Sunfa Ata Zuyan (SAZ) untuk mendeteksi fase bulan secara objektif. Metode yang digunakan meliputi perancangan mekanisme dudukan tipe Alt-Azimuth yang digerakkan oleh motor servo berdasarkan transmisi data nirkabel via protokol TCP/IP, serta penerapan teknik pengolahan citra digital untuk analisis visual fase bulan. Berdasarkan hasil pengujian, sistem mekanik mampu mengikuti koordinat target dengan rata-rata error sebesar 0.17° pada sumbu azimut dan 0.1127° pada sumbu elevasi, sementara kinerja Algoritma SAZ mencatatkan tingkat keberhasilan deteksi sebesar 96.61% pada citra statis dan 70% pada video Bulan dengan waktu komputasi yang cepat. Dapat disimpulkan bahwa prototipe star tracker ini berhasil berfungsi sebagai alat bantu observasi otomatis yang presisi dan responsif dalam melacak serta mengidentifikasi fase bulan.

Observation of celestial objects, especially the moon, is often hampered by the rotation of the earth, which requires manual and continuous adjustment of the telescope position, as well as the high price of automatic tracking systems (GoTo Mounts) on the market. This study aims to design an affordable automatic telescope drive system based on the Arduino Mega 2560 and ESP8266 microcontrollers integrated with coordinate data from Stellarium software, and implement the Sunfa Ata Zuyan (SAZ) Algorithm to detect the moon phase objectively. The method used includes designing an Alt-Azimuth type mount mechanism driven by a servo motor based on wireless data transmission via the TCP/IP protocol, as well as the application of digital image processing techniques for visual analysis of the moon phase. Based on the test results, the mechanical system is able to follow the target coordinates with an average error of 0.1127° on the azimuth axis and 0.17° on the elevation axis, while the performance of the SAZ Algorithm recorded a detection success rate of 96.61% on static images and 70% on videos of the Moon with fast computing time. It can be concluded that this star tracker prototype successfully functions as a precise and responsive automatic observation tool in tracking and identifying the moon phase.
