Abstract

Peserta didik selama ini menggunakan LKPD yang masih memiliki keterbatasan dalam aspek desain dan tampilan. LKPD tersebut hanya disajikan dalam format hitam putih sehingga kurang menarik secara visual. Selain itu, LKPD tersebut cenderung digunakan secara dominan sebagai satu-satunya bahan ajar, sehingga belum mampu mendukung variasi sumber belajar yang lebih kaya pada pelaksaan pembelajaran. Studi ini difokuskan mengembangkan LKPD berbasis Problem Based Learning pada materi Statistika yang layak digunakan, ditunjukkan melalui tingkat kevalidan dan kepraktisannya, serta memiliki tampilan yang menarik dan berwarna. Riset ini mengadopsi model 4D: mendefinisikan, merancang, mengembangkan, dan menyebarkan. Penelitian ini melibatkan ahli materi, ahli desain, ahli bahasa, serta guru mata pelajaran matematika, serta 9 peserta didik kelas X SMA Negeri 11 Rejang Lebong. Temuan riset mengindikasihkan capaian indeks validitas sebesar dapat dilihat dari aspek kevalidan bahasa (0,94), media (0,85) dan materi (0,92), Berdasarkan angka tersebut, kualitas media pembelajaran dinyatakan memenuhi kriteria Sangat Valid. Secara praktikalitas, produk ini mencatatkan skor 97,1% sehingga dinyatakan masuk dalam kategori Sangat Praktis. LKPD berbasis Problem Based Learning yang dikembangkan telah memenuhi kriteria kevalidan dan kepraktisan. Dengan demikian, disimpulkan bahwa LKPD berbasis Problem Based Learning pada materi Statistika yang dikembangkan dinyatakan valid dan praktis digunakan dalam pembelajaran.

Abstract

Mathematical literacy is an important ability for students in Indonesia to face the implementation of minimum competency assessment and learning in the 21st century.This study aims to describe students' mathematical literacy skills in solving problems on pattern material in the Bengkulu local context. This study used a descriptive qualitative design. The research subjects were 30 students grade VIII from five schools in Bengkulu City. Subject selection through purposive sampling technique based on the level of intelligence with the number of each school is six students. Data were collected through interviews and mathematical literacy test using description questions that have been validated and tested. The data analysis consists of data reduction, data presentation, and concluding. The findings of this study are that students with low to moderate knowledge tend to have literacy skills at level 2. In contrast, students in the high knowledge group have literacy skills at level 3. Many students have used mathematical arguments to solve literacy problems but did not use concepts correctly.Students have not used the model structurally at the modeling stage, which resulted in errors in problem-solving and representation. Based on this, teachers need to emphasize the concept of material and mathematical modeling in learning.

Abstract

This study aims to determine the extent to which the Problem Based Learning (PBL) model influences problem-solving ability. The type of research used is experimental research with a Pretest-Posttest Control Group Design. The research subjects were tenth-grade high school students who were divided into two groups: the experimental class, which received learning using the PBL model, and the control class, which received conventional learning. Data were collected through a problem-solving ability test and analyzed using the t-test. The results showed that the problem-solving ability of students taught with the PBL model was better than that of students taught with conventional methods. In addition, PBL learning also enhanced students’ teamwork skills and fostered a sense of responsibility in solving the given problems. Therefore, the PBL model can be considered an alternative in mathematics learning to improve students’ problem - solving abilities.   Keywords: PBL; Problem Solving Skills; Mathematics Learning

Abstract

Purpose of the study: This study aims to determine the validity and practicality of a Problem-Based Learning (PBL) module integrated with the Wordwall application for teaching the topic of similarity in junior high school mathematics. Methodology: The research adopts the Plomp development model, which includes five systematic stages: preliminary investigation, design, realization/construction, test-evaluation-revision, and implementation. Data were collected using expert validation sheets and student practicality questionnaires to assess the quality and usability of the developed module. Main Findings: The results show that the PBL–Wordwall-integrated module achieved a validity score of 89.83% (Very Valid) and a practicality score of 88.5% (Very Practical). The high validity demonstrates that the module’s content, structure, and linguistic elements are consistent with curriculum standards and responsive to learners’ cognitive levels. Likewise, the high practicality indicates that teachers and students found the module engaging, interactive, and easy to apply in classroom settings. Novelty/Originality of this study: The novelty of this study lies in the integration of the PBL approach with digital gamification through Wordwall, creating an innovative learning environment that fosters problem-solving, critical thinking, and motivation simultaneously. Unlike traditional static modules, this design embeds real-world contextual problems within interactive digital activities, bridging pedagogical theory and technological application. This research contributes both theoretically and practically by offering a replicable model for blending inquiry-based learning with gamified platforms in mathematics education. Overall, the developed module is effective, feasible, and capable of enhancing students’ engagement, conceptual mastery, and collaborative learning in mathematics.

Abstract

This study applies graph theory to optimize the placement of electric vehicle (EV) charging stations in Banyumas Regency, Indonesia, using real geospatial data from 27 sub-districts. Each sub-district is modeled as a vertex, with edges defined by a 10 km coverage radius. The domination number is employed to identify the minimum number of charging stations required to ensure full spatial coverage. Unlike prior EV infrastructure studies in Indonesia that primarily rely on demand-based heuristics or clustering methods, this research explicitly guarantees coverage through graph domination theory. To enhance robustness, the domination-based solution is compared with a Set Covering Problem solved using Ant Colony Optimization (ACO). Both approaches consistently identify six strategic locations, achieving 100% coverage while reducing infrastructure requirements by approximately 78% compared to a one-station-per-sub-district strategy. The results provide practical guidance for policymakers and urban planners by supporting cost-efficient, scalable, and equitable EV charging infrastructure deployment in regions with early-stage EV adoption.
