KORESPONDENSI LINTASAN MATAHARI DAN BULAN SEBAGAI DASAR UNTUK MEMBANGUN MODEL DAN DATABASE KECERAHAN SINAR BULAN

Abstract

This paper aims to map the orbit of sun and moon mathematically toward the cartersis coordinate of earth to get the brightness moon light and to develop a database. The model approach proposed is using the trigonometric function. The brightness model of the moon proposed we obtain y = f(x)*100% dengan f(x) = Sin 0.5 x, (0⁰ ≤ x ≤ 360⁰) and the duration of  this brighness data was used to develop the database of the moon brightness in the period infinite bounded.

Keywords: Model, brightness, trigonometric, database, infinite
