Vina,

It is difficult to identify the plant by this type of image. Please post good quality image(s) with flowers and fruits of the plant.

I would guess it as Pittosporum moluccanum of Pittosporaceae family on the basis of this attached publication.

I agree with Arvind Singh in the difficulty of classification of most plants if the picture does not contain flowers or fruits because the leaves do not rely heavily on them in the diagnosis of most plants

I would like to thank Arvind Singh for being informative and helpful to many researchers and I wish success to all

unfortunately, i dont have other image of the plant. my guess is also Pittosporaceae but i'm not really sure what species it is. Thank you so much for your helps its really help my research.
