Low light intensity
Iron or manganese deficiency
Overfertilizationl be brown

not really sure though .
I just c internet guide guess one 

If I'm not mistaken, this is Sansevieria..(common name mother-in-law tongue)
This is a favourite low maintenance  indoor plant .. It needs the soil to be dry between waterings.. So once a week should be enough...
Sometimes, when we buy from nursery, the soil provided in the pot have very high water retention ... This is because they cultivate and keep the plants under plastic shade with controlled watering... When conditions too wet, the roots will rot....Best to change the soil by adding Tanah bakar (coarse red type)
