Forward di-jet production in d+Au collisions at RHIC provides sensitivity toBjorken-x between 0.001 and 0.02 for the nuclear gluon density . The STARexperiment at RHIC has continuous azimuthal coverage with electromagneticcalorimeters for pseudo-rapidity from -1 to 4. We have measuredforward+mid-rapidity $\pi^{0}-\pi^{0}$ and $\pi^{0}-h$ azimuthal correlationsand forward+forward rapidity $\pi^{0}-\pi^{0}$ azimuthal correlations. Bothanalyses use the Forward Meson Spectrometer (FMS) triggered data in RHIC 2008run p+p and d+Au collisions at $\sqrt{s_{NN}}$=200 GeV. The end-capelectromagnetic calorimeter (EEMC) at STAR covers pseudo-rapidity from 1.07 to2. This provides us sensitivity to the nuclear gluon density at intermediate xvalues. Preliminary results on the $\pi^{0}-\pi^{0}$ and $\pi^{0}$ + jet-likeazimuthal correlations with both the FMS and the EEMC will be discussed.
