The problem based on the findings of the Supreme Audit Agency (BPK) on licensing performance checks at the Ministry of Communication and Information Technology (KOMINFO) is that the certification data of telecommunication tools and equipment in the e-certification information system database is incomplete, inaccurate, and invalid in supporting equipment and equipment certification services telecommunication. Based on these conditions, the level of maturity of data quality management is measured. The measurement of the level of maturity of data quality management is carried out using the Modelo Alarcos de Mejora de Datos (MAMD) 2.0 framework. The result of measurement data quality maturity level is level 1, while the expected level is level 2. The strategy to improve the quality of certification data for telecommunication tools and equipment is prepared based on an analysis of the causes of data problems, gaps in the current condition of quality data management and expectations, and regulations related to data governance. The recommendations produced are grouped into eight data discipline points that need to be implemented by the Directorate of Standardization agreeing to reach the desired level of data quality management maturity. Eight points of data discipline are data requirements management, technology infrastructure management, configuration management, historical data management, data security management, data quality control and control, data life cycle management, as well as standard resolutions, policies, and procedures.
