    Abstract
    Solar Tracking System (STS) is an optimal way to maximize the capture of sunlight on solar panel. This research discusses optimizing sunlight’s effectiveness in a solar tracker which has two rotational axes (2 axes) in vertical rotation and horizontal rotation based on NodeMCU ESP8266 as the control center and Fuzzy algorithm. This system consists of 4 Light Dependent Resistor (LDR) light sensors as input consisting of 2 LDR sensors to identify the direction of the movement sun from the east to embers and 2 other LDR sensors to detect the sun’s direction omovement from south to north. These LDR sensors are placed on each side of the outer part of the solar panel. This system needs a 5Wp polycristalline solar panel and an adapter that will be connected to a power source. The driving motor in this system is in the form of 2 servo motors. This system test is still brought out on a laboratory research scale with the help of smartphone lights that are manually driven towards the LDR light sensor. The angle value obtained is determined by the direction of movement of the light that comes to the LDR light sensor. The effectiveness of the light received using a 2-axis solar tracker will be greater than that of a 1-axis solar tracker.
     
    Solar Tracking System (STS) adalah satu dari banyak cara yang optimal demi peningkatan efektivitas pengambilan sinar matahari oleh solar panel. Pembahasan penelitian ini tentang pengoptimalan efektivitas sinar matahari pada solar tracker yang memiliki dua sumbu putar (2 axis) secara rotasi vertikal dan rotasi horizontal dengan berbasis NodeMCU ESP8266 sebagai pusat pengendali dan algoritma Fuzzy. Terdapat 4 sensor LDR sebagai masukan dan sensor LDR ini untuk mengecek arah bergeraknya sinar matahari pada segala arah. Sensor-sensor LDR ini ditempatkan pada setiap sisi-sisi bagian terluar pada solar panel. Sistem ini memakai panel surya polycritalline 5Wp dan satu buah adaptor yang akan disambungkan ke sumber listrik. Motor penggerak pada sistem ini berupa 2 motor servo. Sistem ini diuji dalam masih dalam ruang lingkup penelitian laboratorium dengan bantuan cahaya senter smartphone dan digerakkan oleh manusia kearah sensor cahaya LDR. Nilai sudut yang diperoleh ditentukan arah pergerakan cahaya yang dating terhadap sensor cahaya LDR. Efektivitas cahaya yang diterima menggunakan solar tracker 2 axis akan lebih besar dibanding solar tracker 1 axis.
