Is it permissible for daughters to have the same share as sons in this division, and what is the ruling on the father's division, and what is the solution?

The father's will that the land be inherited by the two daughters is invalid because it is a will to an heir, and it is not valid unless the rest of the heirs agree. Those who participated in purchasing the land or building on it own a share proportionate to what they paid, and this is not part of the inheritance. In case of disagreement, the matter should be referred to the Sharia court or scholarly advice should be sought.
