Could you please help me understand the following order as it reads : Father is found in contempt of coyrt for non-payment of child support,

According to your post, the father was found in contempt of court for non payment of child support. Whether brought by the state or by you personally, you won your case against him. The court imposed a jail sentence on him unless he pays. Your post didn't indicate the due date. The amount due according to your post to avoid jail is 50% of what is owed to you as of August 2015. If the arrears are $20,000 by example, he would need to pay you $10,000 to avoid going to jail.
