    fungsi : buat cek cuaca terbaru
    note   : search locationnya aku pakai google maps, enak, gak kaku search
             nya.. cobain aja hehe. skrep bisa search by query atau input
             koordinat langsung. cek cara pakai di bawah ya!
             sorry yak kalau kadang anomali result. wkwk.
