According to the NI Staatsblad 1905 no.99 (NI Statutebook) the authorities had to hire staff  for the  Inlandsch Hospitaal (Indigenous hospital) at Serang (Bantam). The hospital was a small local hospital financed by the NI Government. Later on its status was improved into a so-called GBZ: Government Civil Hospital.
The personnel that was hired included one mandoer (supervisor) at a monthly pay of f 15 and one male and one female servant at a monthly pay of f 10. Might the number of patients exceed the 40, an additional male or female servant should be employed per 15 patients (above 40). With the same monthly pay of f 10.

The Gouvernementsbesluit (Government Decision) no. 33 of 6 December 1922 (Addendum to the NI Statutebook no. 10212) pubished rules on the status and the tariffs of nursing in the  Government Civil Hospitals. The GBZ at Serang then was classified as a hospital that nursed only 3rd and 4th class patients (tariffs resp. f 3 and f 1.50). This was reaffirmed in the Addendum to the NI Statutebook no. 11446 of 30 August 1927.
