Preparing muster roll - all our workers are on a contract basis then the contractor should prepare the muster

I recently joined a manufacturing company. It is an SSI with approx 20 cr business. the practice here is they are not maintaining muster roll. when I asked the employer if it is mandatory as per law, he said all our workers are on a contract basis then the contractor should prepare the muster (ok up to this) but all staff are on company roll even though the employer is not allowed to prepare the muster roll.
Please suggest to me what should i do in this respect. In last month labour inspector visited our premises he he also queried the same.

Respected Sirs,
Kindly some one suggest on the query raised by Mr.Kulkarni... Even I am looking for the solution.
I am also working for a Manufacturing Company..
When I said my head we have to maintain Muster roll, Entry Exit register for Employees as well as visitors they did not agree that and claiming to be un professionalism..
Kindly suggest us with the Importance of Muster and the consequences of non maintenance.

Dear All
I require Labour compliance Muster Roll Form XII.- FORMAT
Register of Wages Form XIII.
