In the case of Total Permanent Disability or death, the insurer will continue to pay your regular monthly deposits (maximum Rp 5.000.000 or USD 500 per month).
So, at the end of the agreed term, you can still cash in your savings and interest. Alternatively, you can opt to be paid a lunp sum equivalent to the amount of your remaining regular monthly deposits, after the calculation of Net Present Value (NPV) using the prevailing discount rate.
As an illustration, you, as the source account holder (Mandiri Tabungan / Mandiri Giro Rupiah account), open a Mandiri Tabungan Rencana account for your 2 children based on regular monthly deposits of 1 million rupiah for each child over a period of 10 years.
If something happens to you in the 5th year, then the insurer will automatically continue making the regular monthly deposits up to the end of the period (10th year).
Thus, your children will each receive Rp 135,750,230.91 in the 10th year (assuming a 3.00% p.a interest rate, after deduction of tax).
