This research aim is to create the measurement index of the quality of FSLG, using data from APRGE, Notes to FSLG, and ICS. APRGE has many indicators, but the relevant ones are AIS, Competence, Performance, and GGG. The measurement index sourced from APRGE is calculated from the percentage of performance achievement of every indicators. 35 main and 7 conditional indicators are taken from the Notes to FSLG. The ICS has 101 indicators. Samples are 25 Local Governments of provinces, cities, and municipals since 2015 to 2018. Software E-Views 8 is used for statistical computation. The output of the measurement index is the FSLG quality assessment category. The index can be used to measure the quality of FSLG produced by Local Governments. The results of statistical testing show that Competence and GGG affect the Quality of FSLG. Meanwhile, AIS and Performance do not. However, AIS and Performance can still be used to measure the Quality of FSLG. AIS is a primary need that cannot be left out in the process of presenting FSLG. Likewise for Performance, each Local Government already has its own KPI which will make CSA work properly following the rules, including in the preparation of the FSLG. The implication is to facilitate the internal and external parties in assessing and improving the quality of FSLG.
