Meningkatkan Disiplin Diri melalui Bimbingan Klasikal Berbasis Komunikasi Asertif pada Peserta Didik SMK

Abstract

ABSTRACT

This study aimed to determine the effect of classical guidance services using assertive communication techniques on the self-discipline behavior of eleventh-grade Hospitality students at SMKN 2 Kediri. The study employed a quantitative approach with an experimental method using a One Group Pretest-Posttest Design. The sample consisted of 69 students selected through total sampling. Data were collected using a self-discipline questionnaire that had met validity and reliability requirements. Data were analyzed using the Wilcoxon Signed Rank Test because the data were not normally distributed. The results showed that the mean self-discipline score increased from 78.91 in the pretest to 128.25 in the posttest. Hypothesis testing yielded an Asymp. Sig. (2-tailed) value of < 0.001, which was lower than 0.05. Therefore, classical guidance services using assertive communication techniques had a significant effect on improving the self-discipline behavior of eleventh-grade Hospitality students at SMKN 2 Kediri.
