The first legislative and presidential elections were held simultaneously on  17 April 2019. One of the parties that contributed to the implementation of the 2019 election was the organizer of the ad-hoc election. In carrying out its duties, of course, it is not free from various obstacles. This paper aims to evaluate ad-hoc domestic election organizers in the 2019 election and provide input for the next election which is expected to be even better. The method used in this writing is a qualitative approach to literature study. Ad-hoc election organizers have an important role in the running of the 2019 simultaneous elections. Elections for president/vice president and legislative bodies simultaneously have complexities, including for PPK, PPS, and KPPS personnel. In addition, the various types of alleged violations that occurred at TPS need to be noted for improving the performance of ad-hoc election organizers in the next election. The large number of ad-hoc election organizers who are sick and die requires further in-depth research to improve the work system and recruitment for the next election. Ad-hoc election organizers are also entitled to social security in the form of Employment BPJS while carrying out their duties.
