The principle of fast, simple and low-cost justice has been regulated in Law Number 48 of 2009 concerning Judicial Power. However, in practice the application of these principles actually often results in accumulation of material and overlapping cases, the formulation of the problem is how to apply the principle of simple, fast and low costs and what factors influence the application of these principles in the Class II Banyumas District Court. The aim of the research is to find out the application and factors that influence the simple, fast and low cost state state courtprinciples in the Class II Banyumas District Court. Descriptive research, empirical juridical approach methods and interviews were used as additional data sources in this research. The research location is at the Class II Banyumas District Court. The research results show that the Class II Banyumas District Court has implemented the principles of fast, simple and low-cost justice, but there are still cases that are resolved in more than 5 (five) months because SEMA No. 2 of 2014 is a new regulation promulgated on March 13 2014. In its implementation at the Class II Banyumas District Court it did not immediately run effectively, while the factor that influenced the application of the simple, fast and low cost principle at the Class II Banyumas District Court was the number of cases submitted relatively many while the courtroom is limited; the prosecutor's readiness in preparing the Indictment, Defense Memorandum and Charges; defendants who are sometimes uncooperative in following the trial process; and judges who are sometimes unable to attend trials because they are attending training or other activities that cannot be missed. The suggestion is that all parties involved in the justice system, including judges, prosecutors and legal advisors (advocates), must provide commitment and support for the realization of simple, fast and low-cost justice by consistently being able to attend trials according to the predetermined schedule.
