Abstract

Thematic Literacy Student Community Service Program (KKM) of Group 35, Sultan Ageng Tirtayasa University, was implemented from July 8 to August 7, 2025, at the Sumber Ilmu Library, Mekarsari Village, Rajeg Subdistrict, Tangerang Regency. This activity aimed to revitalize the function of the village library as a literacy center and to improve the reading skills of elementary school students. The implementation method employed a participatory approach through coordination with schools, library managers, the village government, and the community. The main programs included Read Aloud, Read Me a Book, Smart Book Review, Book-Based Project and Story Creation, and Village-Level Literacy Appreciation. Supporting programs comprised reading tutorials, creative competitions, healthy exercise sessions, and communal work (gotong royong). The results indicated increased participation of students from SDN Sukasari 2, enhanced creativity, and strengthened communication skills through storytelling competitions. Program sustainability was achieved through the commitment of village youth volunteers to continue weekly reading tutorials and the routine scheduling of healthy exercise sessions by the karang taruna (youth organization). In conclusion, the revitalization of the village library through the Thematic Literacy KKM has proven effective in fostering reading interest, creativity, and social interaction among children, while simultaneously reinforcing the library’s role as an active community learning center.Keywords: Literacy; Village Library; Community Service; KKM; UNTIRTA

Abstract

Mastery of the concept of surface area in solid figures remains a challenge for junior high school students, particularly in linking three-dimensional representations with their corresponding nets. This study aimed to examine the effectiveness of transparent solid figures as concrete learning media in improving students’ understanding of surface area concepts. Conducted at SMPIT Al Mubarok, Serang City, during the 2025/2026 academic year, the study employed a quantitative method using a one-group pretest–posttest experimental design. Thirty ninth-grade students were selected through accidental sampling based on accessibility and availability. A concept comprehension test was administered before and after the treatment, and data were analyzed descriptively and inferentially. Results indicated that students’ surface-area comprehension improved significantly following the use of transparent concrete instructional media. The mean pretest score of 81.43 increased to 100 on the posttest. The Wilcoxon Signed-Rank Test revealed a significance value of 0.000 (<0.05), and the N-Gain score of 1.00 was categorized as high, confirming that transparent solid media were highly effective in enhancing students’ conceptual understanding of surface area.

Abstract

This study aims to examine the effectiveness of implementing a discovery learning model combined with scaffolding techniques in improving students' mathematical problem-solving competencies through a Systematic Literature Review approach. The underlying problem of this study is the low ability of students to solve mathematical problems due to the dominance of conventional learning approaches that are still teacher-centered. The Discovery Learning model provides opportunities for students to construct conceptual understanding independently, but in practice, students often require guidance. Therefore, scaffolding techniques are needed to direct the learning process to be more systematic and meaningful. This study analyzed 15 scientific articles with a publication period of 2020–2025 from Google Scholar, Publish or Perish, Sinta, and Garuda using the PRISMA-based Systematic Literature Review method. The analysis of these findings can be concluded that Discovery Learning assisted by scaffolding is proven to be effective in improving mathematical problem-solving abilities the use of this model is better than the use of conventional models. Scaffolding supports each stage of problem-solving, reduces cognitive load, and increases student motivation. The integration of Discovery Learning assisted by scaffolding, effectively develops students' mathematical problem-solving abilities
