This study aims to determine whether group guidance incorporating the bentengan game has an influence on the self-confidence of Grade XI LAS 1 students at SMK Negeri 2 Tarakan. Low student self-confidence was indicated by observable behaviors such as appearing nervous when speaking in front of the class, consistently seeking assistance before attempting tasks independently, rarely raising their hand or answering questions even when knowing the correct answer, and limited interaction with classmates during group activities. One approach that can be undertaken to address this issue is through group guidance services incorporating the bentengan game. The study employs a quantitative approach using experimental research. The research design applied is a applied is a pre-experimental design in the form of a one-group pretest-posttest design. Data were collected using a self-confidence scale. The study population consisted of 59 students in Grade XI LAS 1 at SMK Negeri 2 Tarakan, with a sample of 12 students selected using simple random sampling. Data were analyzed using descriptive and inferential statistics with the aid of SPSS version 21. The pretest results indicate that students' self-confidence scores fell within the low to very high category, with a mean score of 71.50. Following the intervention, the posttest results show an improvement, with scores falling within the high to very high category and a mean score of 80.41. Based on hypothesis testing using the Wilcoxon Signed-Rank Test, a significance value of 0.002 was obtained, which is below the threshold of 0.05. Consequently, the alternative hypothesis (Ha) is accepted, and the null hypothesis (Ho) is rejected, indicating that group guidance incorporating the bentengan game has a significant influence on the self-confidence of Grade XI LAS 1 students at SMK Negeri 2 Tarakan.
