Abstract

The purpose of this study was to determine the significant or not influence of the level of service and relational promotion on the decision to stay at the Platinum Rantauprapat hotel. The study used quantitative methods and through an associative causality approach. The data collection technique used was through observation and interviews. The sample in this study was 50 respondents or consumers. The sampling technique was simple random sampling. The data analysis technique used statistical techniques/SPSS by conducting validity and reliability tests then for questionnaires and multiple linear regression analysis with the T Test and F Test to prove the hypothesis. The results of the study showed that there was a close and significant influence of the level of service on the decision to stay, there was a close and significant influence of relational promotion on the decision to stay, the influence of friendliness to customers and the availability of goods was 98.6% and the remaining 1.4% was influenced by other factors and variables

Abstract

This study aims to examine the effectiveness of the Discovery Inquiry method in improving students’ creative poetry writing skills among eighth-grade students at SMP Negeri 1 Silangkitang. The research employed a Classroom Action Research (CAR) design consisting of four stages: planning, implementing actions, observing, and reflecting. The participants were 25 students from class VIII. Data were collected through classroom observations, student interviews, and analysis of students’ poetry. The results show that the Discovery Inquiry method significantly enhanced students’ performance in writing poetry. The average score increased from 68.4 in the first cycle to 86.2 in the second cycle, marking a 26% improvement. Students showed notable progress in creativity, word choice accuracy, and mastery of poetic structure. Moreover, their self-confidence, critical thinking ability, and willingness to experiment with language and poetic forms also improved. During the implementation, students became more engaged and active in the learning process, as they were encouraged to explore ideas and express emotions freely through poetry. The findings indicate that the Discovery Inquiry method not only develops technical writing skills but also nurtures creative expression and motivation to learn literature. Therefore, this method can be considered an effective and student-centered strategy for enhancing poetry writing skills and promoting creative learning in language and literature classes.

Abstract

Mathematical critical thinking is a fundamental competency in mathematics education; however, instructional practices often provide limited opportunities for students to engage in reasoning, inquiry, and reflective thinking. While ethnomathematics has been increasingly integrated into mathematics learning, most studies emphasize cultural artifacts as contextual resources rather than cultural practices as mechanisms of thinking. This study explores the role of Bilah Panai cultural practices, namely pantun and merisik/telangkai, in enhancing students’ mathematical critical thinking skills. Pantun was implemented as a cognitive activation strategy to stimulate prior knowledge and interpretation, whereas merisik/telangkai was adapted as a local inquiry process that encouraged investigation, discussion, argumentation, and collaborative problem solving. The study involved Grade 10 students participating in mathematics learning activities grounded in Bilah Panai cultural practices. Data were collected through classroom observations, students’ mathematical critical thinking assessments, and learning activity documentation. The findings indicate that pantun supported students in identifying mathematical ideas and constructing initial interpretations, while merisik/telangkai facilitated reasoning, analysis, and problem-solving processes. These cultural practices created meaningful learning experiences and promoted active engagement in mathematical inquiry. The study highlights the potential of local cultural practices to function not merely as learning contexts but as cognitive and inquiry mechanisms that support the development of mathematical critical thinking. This finding contributes to the advancement of ethnomathematics and culturally responsive mathematics education. Quantitative findings showed an improvement in students’ mathematical critical thinking scores from a mean pretest score of 58.60 to a mean posttest score of 88.20, yielding a high normalized gain score (g = 0.715). Keywords: Mathematical Critical Thinking; Ethnomathematics; Bilah Panai Culture; Pantun; Local Inquiry; Culturally Responsive Mathematics Education.
