Hello Liana,
There's a list of OFBiz service providers at
https://cwiki.apache.org/OFBIZ/apache-ofbiz-service-providers.html . That list does not appear to include any company in Indonesia.
Some people from Indonesia have participated in the OFBiz mailing lists:
http://ofbiz.135035.n4.nabble.com/template/NamlServlet.jtp?macro=search_page&node=135036&query=indonesia . You could try and make contact with them perhaps.
Cheers
Paul Foxworthy
