Abstract

Usaha Mikro, Kecil, dan Menengah (UMKM) berperan penting dalam menciptakan lapangan kerja dan menjaga stabilitas ekonomi, namun di pedesaan masih terkendala adopsi digital yang terbatas pada promosi dari mulut ke mulut. Penelitian ini berfokus pada pemberdayaan UMKM di Desa Raya Dusun IV melalui optimalisasi Google Maps guna meningkatkan literasi digital, memperluas pasar, dan memperkuat daya saing. Metode yang digunakan meliputi sosialisasi, pelatihan, dan pendampingan teknis untuk mendaftarkan serta mengelola lokasi usaha di Google Maps. Hasil penelitian menunjukkan bahwa digitalisasi lokasi secara signifikan meningkatkan visibilitas, aksesibilitas, dan kepercayaan konsumen, sehingga berdampak positif pada peningkatan penjualan UMKM.

Abstract

Purpose of this study is to: to find out the objective conditions of local superiority in mathematics learning in elementary schools in Central Aceh Regency, to design mathematical learning models based on local superiority of class I students, and to find out student responses to local excellence based mathematics learning models in Central Aceh Regency. The subjects of this study were all 4th grade students of elementary school in Bebesen Central Aceh District. And the samples are SD 1 Bebesen, SDN 2 Bebesen, SDN 5 Bebesen, SDN 8 Bebesen, SDN 9 Bebesen, SD 10 Bebesen, SDN 10 Bebesen, SDN 11 Bebesen, SDN 12 Bebesen, SDN 14 Bebesen, SDN 16 Bebesen, SDN 16 Bebesen, SDN 17 Bebesen, SDN 17 Bebesen, SD IT Scholar. The research results were obtained that: (1) the objective conditions of mathematics learning of elementary students in Central Aceh Regency as follows. a) In the learning process the teacher has not linked mathematics with the local character and potential of the area. b) The mathematics handbook used today has not linked students' personal character. (2) During the learning process of mathematics based on local excellence and the potential character of antusius elementary school students to learn mathematics, the steps of the local superiority-based learning model are (a) the teacher conditions the class, starts with prayer by preparing facilities and infrastructure, doing Apperception of the local potential of central Aceh district b) Presenting contextual problems, Explicitly negotiating, Cooperative intervention, guiding students in groups to discuss contextual issues contained in the LAS. Give students the opportunity to present their model findings through class discussions. c) Guiding students to formulate the results of the discussion while making a summary of the material discussed, Providing material evaluations through giving quizzes or home assignments. The design of elementary school mathematics learning based on locally designed excellence received a good response from all students. 83.74% of students gave a positive response to the local excellence-based learning model. From these results it is expected that the mathematics learning model in the class must be tailored to the needs of students so that the objectives of the learning process can be achieved maximally.

Abstract

Mathematical communication is a fundamental competence that enables students to express, interpret, and justify mathematical ideas clearly; however, many junior high school students still demonstrate low proficiency in this skill. This study examines the effect of the Problem Submission and Solving (JUCAMA) learning model on students

Abstract

Purpose: This study responds to the limited comprehensive evaluations on research trends in school mathematics education through bibliometric approaches, particularly within the past decade. The main aim is to systematically examine how research in school-level mathematics education has evolved from 2015 to 2024 using bibliometric analysis. Method: Publication data were obtained from the Scopus database, with analyses conducted using VOSviewer and the R-Bibliometrix package. These tools were employed to map out key areas such as scientometrics, patterns of scholarly collaboration, institutional participation, and shifts in research methodology. In total, 3,053 documents containing the keywords “mathematics education” and “school” were included in the analysis. Findings: The results reveal a significant surge in publications since 2020, which coincides with the educational challenges brought about by the COVID-19 pandemic. Research in this field has increasingly emphasized the integration of technology, interdisciplinary STEM perspectives, and applied science. The United States and Indonesia have emerged as leading contributors, underlining their active institutional engagement and influential roles in shaping the global landscape of mathematics education research. Most studies continue to be published as scientific articles. Significance: This study provides a thorough overview of recent developments in school mathematics education research. The insights gained are expected to support educators, researchers, and policymakers in formulating more effective and adaptive strategies for the future of mathematics teaching and learning.
Students’ errors in solving problems involving the polar form of complex numbers: An analysis based on kastolan’s stages Lubis, Nur Ainun; Zaiyar, M.; Harahap, Rosliana; Umar, Ali

Abstract

Purpose: The application of Kastolan's error analysis framework to the polar form of complex numbers remains limited, leaving a gap in the diagnostic literature for undergraduate mathematics education. This study aims to describe and classify the errors made by students when solving complex number polar form problems based on Kastolan's error stages: conceptual, procedural, and technical, to provide an empirical basis for more targeted instructional strategies in complex analysis.Method: A qualitative descriptive approach was employed. Data were collected through a written descriptive test and documentation of student answer sheets, which were analysed using Kastolan's error classification rubric. The research subjects were 21 seventh-semester Mathematics Education students at UIN North Sumatera who had completed the Complex Analysis course. Three students were selected through purposive sampling to represent each dominant error category.Findings: Three dominant error types were identified. Conceptual errors appeared in incorrect identification of arguments and angular quadrants. Procedural errors occurred when students bypassed the required polar form in division operations. Technical errors involved incorrect values of special angles and trigonometric function signs.Significance: These findings provide an empirical basis for lecturers to design targeted learning strategies addressing concept understanding, procedural order, and computational accuracy in complex number polar form instruction.

Abstract

Adversity Quotient (AQ) is widely theorized to predict student engagement in challenging mathematics learning, yet the assumption that this stable psychological trait manifests directly in observable classroom behavior has rarely been tested with direct observational data, particularly within Indonesian madrasah aliyah populations. This study aimed to (1) profile the AQ of Grade X students at a state Islamic senior high school along Stoltz's three categories and four CO₂RE dimensions, and (2) examine whether AQ category is reflected in observable activity during Problem-Based Learning (PBL). A descriptive quantitative design was applied to 20 purposively selected students. Data were collected via an adapted Adversity Response Profile (21 items; Gregory content validity = 0.952; Cronbach's α = 0.90) and a 17-indicator observation sheet covering the five PBL syntactic phases (1–5 scale). Three findings emerged. First, the AQ distribution was dominated by low- and moderate-resilience profiles (50% Quitters, 45% Campers, 5% Climber), converging strikingly with the larger ARP-ML survey of (Gradini & Noviani, 2025) and indicating a possibly structural pattern of low resilience among Indonesian mathematics learners. Second, the CO₂RE dimensions, although uniformly classified as High to Very High, were unevenly develop. Control and Reach were strongest (81.25%), while Origin and Ownership lagged (75.38%), with the weakest single item reflecting anxiety about group-leadership responsibility. Third, AQ category was essentially uncorrelated with observable PBL activity (r = 0.156). A Quitter recorded the second-highest activity score, while the only Climber recorded below-average activity. This trait-process dissociation suggests that AQ operates over cumulative learning timescales rather than within single sessions, and that group-based PBL may function as social scaffolding that compensates for individual trait limitations. The study contributes the first direct observational test of the AQ-PBL behavioral linkage in an Indonesian madrasah context and identifies Origin and Ownership as a priority pedagogical target.
