Abstract

The basic problem of the research study is the mastery of reduplication on the ability to understand discourse, so the purpose of the study is to determine the relationship between mastery of reduplication and the ability to understand discourse by students of the Even Semester of the Indonesian Language Education Study Program, FKIP-USI, Academic Year 2023/2024. To analyze the research data, a correlational method was used for two research variables, namely mastery of reduplication (X) and ability to understand discourse (Y). The research population was all students of the Even Semester of the Indonesian Language Education Study Program, FKIP-USI, Academic Year 2023/2024, totaling 193 people, so the researcher took 15% of the population as a research sample, so that 30 people were obtained randomly. The research instrument was a multiple-choice test with 20 questions for each research variable and 4 possible answer choices (options). Based on the results of the data normality test for the reduplication mastery variable, the value of c² count <c² table (0.05) was obtained, namely 5.210 <11.070 (normally distributed data). Likewise, for the discourse comprehension ability variable, the value of c² count <c² table (0.05) was obtained, namely 8.291 <11.070 (normally distributed data). The results of the homogeneity test of the research variables obtained a value of F_h<F_table (0.05%) = 1.35 <1.85. This means that the research variables have homogeneous variance. There is a positive and significant relationship between reduplication mastery and discourse comprehension ability by Sem.Genap students of the Indonesian Language Education Study Program, FKIP-USI, Academic Year 2023/2024. This is evidenced by the results of the t-test data analysis obtained that the t_h > t_table at a significance level of 5%, namely 4.05> 2.00.
