Abstract

This research aims to document and analyze semiotic studies in Serdang Malay Ethnomedicine mantra texts, especially regarding signs and markers which are believed to have spiritual power in Kuala Lama Village, Serdang Bedagai Regency, North Sumatra. This research uses a qualitative approach with field data obtained through observation, in-depth interviews and documentation. The results of this research show that in the old Malay Serdang mantra, there are two main signs, namely the sound or phrase "Bismillahirrohmanirrohim" which always appears at the beginning or above the mantra sentence. The two words "Hu" have a social meaning as a place to express requests for desires, recognition of human helplessness, and special sentences in begging. The research conclusion shows that the semiotic social meaning of the old Malay Serdang mantra lies in the sound "Bismillahirrohmanirrohim," which is an expression of a request for healing to God. In the context of ethnomedicine treatment, the use of this mantra also reflects cooperation and mutual assistance between the Serdang Malay community.

Abstract

This study investigates the correlation between students' reading interest at home and their summary writing ability among fifth-grade students at UPT SD Negeri 060819 Medan during the 2025-2026 academic year. The research employed a quantitative correlational design with 25 fifth-grade students as participants. Data were collected through a reading interest questionnaire and a summary writing test. Results from normality testing indicated that data were normally distributed (significance value = 0.086 > 0.05), confirming the appropriateness of parametric statistical analysis. The Pearson Product Moment correlation analysis yielded a correlation coefficient of 0.811, which exceeded the critical value of 0.396 at a 5% significance level (N = 25), leading to acceptance of the alternative hypothesis. The coefficient of determination (R² = 65.77%) indicates that approximately 66% of the variance in summary writing ability can be explained by reading interest at home. Based on interpretation guidelines, this correlation coefficient of 0.811 represents a very strong positive relationship. These findings demonstrate that students with higher reading interest at home demonstrate correspondingly better summary writing abilities. The study concludes that fostering reading interest among students, both in family and school environments, should be prioritized to enhance literacy skills, particularly in written expression and comprehension

Abstract

This study aims to determine the effectiveness of interactive learning media based on the Canva application on poster-writing abilities of grade VI students of STATE ELEMENTARY SCHOOL 060875 Medan in the 2025-2026 ACADEMIC YEAR. This study used a quantitative method with an experimental approach, specifically a Pre-Experimental Design with a One Group Pretest-Posttest Design. The research sample was all 57 students, selected using Purposive Sampling technique. Data were collected through observation sheets of student and teacher activities, test sheets (pretest and posttest) to measure poster writing skills, and documentation. The results of the descriptive statistical analysis showed that the average pretest score of students' poster writing skills was 43.44, with 100% of students (57 people) not completing the KKM based on the 70. After being given treatment using Canva media, the average posttest score increased significantly to 78.58, with 96.5% of students (55 people) achieving completion. The average increase in scores from pretest to posttest was 35.14%. The results of the normality test showed that the posttest data were not normally distributed, and the homogeneity test showed that the data were not homogeneous. Nevertheless, the hypothesis test using the Paired Samples t-test (noting that a non-parametric test such as the Wilcoxon Signed-Rank Test would be more appropriate given the violation of the assumptions) yielded a significance value (Sig. 2-tailed) of 0.000. Since the significance value of 0.000 < 0.05, the Null Hypothesis (H0) is rejected and the Alternative Hypothesis (H1) is accepted. Based on the results of this study, it is concluded that the use of interactive learning media based on the Canva application is very effective in improving poster writing skills in sixth-grade students at UPT SD Negeri 060875 Medan. Canva media has been proven to improve cognitive learning outcomes and student activity during learning

Abstract

This study investigates the effectiveness of YouTube learning videos in enhancing fifth-grade students' comprehension of procedure text structures at UPT SD Negeri 064004 Medan during the 2025-2026 academic year. Initial observations revealed low student comprehension of procedure texts and insufficient variety in teaching media utilized by educators. This qualitative descriptive research involved 22 fifth-grade students who engaged with a YouTube video from the "Titiz Craft" channel titled "Creative and Unexpected Ideas from Waste Materials." Data were collected through observation, interviews with both teachers and students, documentation, and procedure text writing assessments. Results demonstrated significant improvements in student understanding, with mean scores of 84.63 (categorized as "Good"). Of the 22 students, 6 (27.27%) achieved "Very Good" category (86-100), 14 (63.63%) attained "Good" category (75-85), and 2 (9.09%) scored in the "Sufficient" category (56-74). No students fell into the "Poor" category. The findings indicate that video-based learning effectively supports students' comprehension of procedure text structures through concrete visual representation and enhanced classroom engagement

Abstract

This study was motivated by the low ability of fourth-grade students at UPT SD Negeri 064956 Medan to understand fable texts. Preliminary observations indicated that most students struggled to analyze the intrinsic elements of fables, showed low levels of participation and enthusiasm in learning, and were subject to predominantly lecture-based instruction, which failed to capture their interest. These conditions revealed a gap between the learning objectives and students' actual achievements, highlighting the need for innovation in the learning model. The population and sample comprised all 28 fourth-grade students of UPT SD Negeri 064956 Medan. Data were collected through fable comprehension tests (pre-test and post-test), observations, interviews, and questionnaires. The results showed a significant improvement in students’ ability to understand fable texts after the implementation of the Jigsaw model. In Phase 1 (before the Jigsaw model was applied), the average comprehension score was 63. Of the 28 students, 18 (64.3%) had not yet met the Minimum Mastery Criteria (KKM) of 75, and only 10 students (35.7%) were in the “good” category (scores between 75–84). After applying the Jigsaw cooperative learning model in Phase 2, the average student score increased sharply to 88. All 28 students (100%) achieved scores within the “very good” category (85–100), successfully exceeding the KKM. This increase from an average of 63 to 88 strongly indicates that the Jigsaw cooperative learning model is effective in enhancing students’ comprehension of fable texts. This success is attributed to the characteristics of the Jigsaw model, which promote active participation, collaboration within expert groups, and individual responsibility in sharing knowledge. Questionnaires and interview responses also reflected positive feedback from both students and teachers, indicating that the model made the learning process more enjoyable, easier to understand, and helped develop students’ discussion skills and self-confidence

Abstract

This study investigated the effect of a card box game strategy on the speaking ability of young children in Group A (aged 4–5 years) at One-Roof Kindergarten SDN 146 Kayu Laut, Mandailing Natal Regency, Indonesia, in the 2025–2026 academic year. The intervention addressed low speaking skills characterized by limited vocabulary, reluctance to express opinions, and minimal oral interaction among peers. A quantitative approach with a quasi-experimental one-group pretest–posttest design was employed. Fifteen children participated in four sessions of learning activities using a card box game, an educational medium containing thematic pictures and symbols designed to stimulate oral language. Speaking ability was assessed through observation on three indicators: mentioning familiar words, answering questions appropriately, and imitating writing and pronouncing letters. The mean pretest score was 48.00, with most children categorized as “Not Yet Developed” or “Starting to Develop”. After the intervention, the mean posttest score increased to 82.67, with a predominance of the “Very Well Developed” category. A paired-samples t-test yielded t(14) = 15.53, exceeding the critical value at the 5% significance level, indicating a statistically significant improvement. These findings demonstrate that the card box game strategy is an effective, play-based approach for enhancing young children’s speaking ability

Abstract

This study investigates the correlation between home reading habits and Indonesian language learning outcomes in identifying main ideas in reading texts among sixth-grade students. The research was motivated by observations of low home reading frequency and suboptimal achievement in determining main ideas in Indonesian texts. A quantitative correlational design was employed. The population comprised all 30 sixth-grade students of State Elementary School 357 Natal, Mandailing Natal Regency, in the 2025–2026 academic year; total sampling was applied. Data on home reading habits were collected using a Likert-scale questionnaire, while learning outcomes in determining main ideas were measured through a validated achievement test. Both instruments met requirements of validity and reliability, and data distributions were normal and linear. The results showed a moderate, positive, and statistically significant correlation between home reading habits and Indonesian language learning outcomes (r = 0.5526, t = 3.507, df = 28, p < 0.01). The coefficient of determination indicated that home reading habits accounted for 30.5% of the variance in students’ scores for determining main ideas. These findings underscore the importance of cultivating regular reading practices at home, supported by parents and schools, to enhance reading comprehension—particularly the ability to identify main ideas in Indonesian language texts

Abstract

This study aims to develop contextual-based Indonesian language teaching materials to improve the reading ability of grade VIII students of SMP Negeri 7 Siobon, Mandailing Natal Regency. The background of this study is the low reading ability of students caused by the lack of interesting, contextual teaching materials, and in accordance with student needs and curriculum. This study uses a Research and Development (R&D) approach with a modified Borg and Gall development model. The development process was carried out through the stages of preliminary study, planning, product development, expert validation, limited trials, product revision, and field trials. The trial subjects were 30 grade VIII students, with data collected through validation questionnaires, student response questionnaires, and reading ability test instruments. The teacher's assessment also showed an average score of 4.2–4.5, which was categorized as good to very good. At the field trial stage, the average score of student responses to the teaching materials was 3.8 (good category), covering aspects of content suitability (3.98), language and image readability (3.7), material presentation (3.8), and visual appearance (3.7). In addition, from the results of the effectiveness test, there was an increase in students' reading ability based on the results of the pretest and posttest. Students showed an increase in scores on the indicators of the ability to find explicit and implicit information, and to conclude the contents of the reading. The developed teaching materials present contextual reading texts, reflective activities, evaluations, and exercises that are arranged based on a contextual approach by considering the students' environment and culture. Learning is arranged in stages and encourages students to think critically and actively in understanding the contents of the reading. Thus, the developed teaching materials are proven to be feasible, practical, and effective in improving the reading skills of grade VIII junior high school students

Abstract

This study aims to determine the effectiveness of implementing the playing method as a learning strategy in developing beginning reading skills in grade I students of State Elementary School 050 Malintang Julu, Mandailing Natal Regency, Academic Year 2025–2026. The main problem raised in this study is the low beginning reading ability of students due to the use of monotonous learning methods that are not in accordance with the characteristics of early age development. The research method used is a quantitative approach with a quasi-experimental design, using a one group pretest-posttest design model. The research subjects were 22 grade I students. The instruments used included an initial reading test and a student activity observation sheet. Data analysis was carried out using the t-test and regression test using SPSS version 25. The results showed that the application of the play method had a positive impact on improving students' initial reading skills. The results of the t-test showed that there was a significant difference between the pretest and posttest results (t count = 1.717, t table = 1.720, α = 0.05). Although statistically the t count value was slightly smaller than the t table, the results of direct observation, positive correlation value (r = 0.186), and simple linear regression results Y = 102.943 + 0.254X indicated that the play method had an effect on improving student learning outcomes. The effect of the play method on initial reading skills was 35%, while the rest was influenced by other factors. Thus, it can be concluded that the play method is effectively used as a learning strategy to develop early reading skills in grade I elementary school students. This method is able to create a fun learning atmosphere, motivate students, and increase their activeness and involvement in the reading learning process

Abstract

This study aims to analyze the comparative results of Indonesian language learning through the use of PowerPoint and picture media on the writing ability of fourth grade students of State Elementary School 112 Parbangunan, Mandailing Natal Regency in the 2025–2026 Academic Year. The background of this study is the low writing ability of students due to the lack of variety of learning media used. Writing is a basic skill in learning Indonesian that needs to be developed early on because it is closely related to the ability to think, organize ideas, and communicate thoughts in writing. This study uses a comparative quantitative approach with a Nonequivalent Control Group Design. The population of the study was all 40 fourth-grade students of SD Negeri 112 Parbangunan, divided into two groups: class IVA as the experimental group with PowerPoint media and class IVB as the control group with image media. The research instrument was a writing test given during the pretest and posttest. The data analysis technique used a normality test, homogeneity test, and t-test to determine significant differences between the two groups. The results showed that the average posttest score of students who learned with PowerPoint media was higher than students who used image media. Based on the t-test, the t-count value was 2.27 with a t-table of 2.024 at a significance level of 0.05. Because t-count> t-table, there is a significant difference between the two media. Thus, it can be concluded that PowerPoint media is more effective than image media in improving students' writing skills
