Abstract

Based on the results of initial observations at SMP Negeri 40 Medan, there are teachers who have not maximized the design, development, and utilization of learning media, especially flipbook media that has never been implemented. As well as the mathematical literacy skills and learning motivation of students are still low. This study aims to (1) produce flipbook media based on the Problem Based Learning learning model that is valid, practical and effective, (2) analyze the improvement of mathematical literacy skills and (3) analyze the improvement of student learning motivation using flipbook media based on Problem Based Learning. This study uses the ADDIE model. This study involved class VIII students of SMP Negeri 40 Medan. The instruments used in the development of flipbook media are Teaching Modules, LKPD, Mathematical Literacy Ability Tests and Student Learning Motivation Questionnaires. The results of the study are that the flipbook media meets the valid criteria with a score of 4.69, then the flipbook media was tested to obtain practical and effective media so that it meets the practical criteria with a score of 88.95, and the flipbook media meets the effective criteria with a score of 87.79. The increase in mathematical literacy skills measured by N-gain on the development trial conducted twice against pretest with posttest I with an average N-gain of 0.33 in the medium category, then against posttest I and posttest II with an average N-gain of 0.73 in the high category. Furthermore, the increase in students' learning motivation by measuring the pretest and posttest with an average N-gain of 0.6 in the medium category. Based on the N-gain results, it is stated that flipbook media based on the Problem Based Learning learning model is able to improve students' mathematical literacy skills and learning motivation at SMP Negeri 40 Medan.

Abstract

This study emphasises the application of mathematical and computational modelling to support multi-criteria decision-making in the selection of online transportation services. Using Microsoft Excel, the research employs the Weighted Product (WP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) methods to assess alternatives based on six quantitative criteria: price, promotion, service variety, payment method, convenience, and punctuality. The integrated application of WP and TOPSIS provides a systematic process of normalisation, weighting, and ranking to determine the optimal alternative. The findings indicate that GOJEK achieves the highest preference value (0.6107), followed by GRAB (0.5533), IN-DRIVE (0.5000), and MAXIM (0.3893). The methodological contribution of this research lies in demonstrating how the integration of WP and TOPSIS within computational tools establishes an effective mathematical framework for optimising decision-making in service evaluation.

Abstract

Program pengabdian ini bertujuan meningkatkan kapasitas perajin batik melalui pendampingan desain batik digital menggunakan aplikasi Ambatig untuk mempercepat perancangan dan menata konsistensi pengulangan motif tanpa menghilangkan identitas Batak–Melayu. Kegiatan dilaksanakan selama empat minggu melalui sosialisasi, pelatihan, penerapan teknologi, dan pendampingan dengan pemanfaatan pengaturan pola frieze (satu arah) dan kristalografi (dua arah). Evaluasi melibatkan 15 peserta menggunakan angket skala Likert pada lima poin serta observasi terhadap durasi pradesain, jumlah varian desain, dan kesalahan sambungan pola. Hasil menunjukkan rerata kepuasan peserta di atas skor 4 dengan sekitar 80% respons positif, terutama pada aspek kesesuaian gaya visual (4,5) dan kemudahan dipelajari (4,3). Secara operasional, waktu pradesain berkurang dari sekitar 90 menit menjadi 40–50 menit per varian, peserta mampu menghasilkan 2–3 varian desain dalam 90 menit, dan kesalahan sambungan pola berkurang. Program ini juga menghasilkan portofolio desain digital berisi parameter siap produksi. Dengan demikian, pemanfaatan Ambatig efektif meningkatkan efisiensi dan kerapian perancangan motif batik serta mendukung pelestarian dan keberlanjutan motif Batak–Melayu melalui dokumentasi digital dan penguatan kapasitas perajin lokal.

Abstract

Line integrals are one of the fundamental concepts in advanced calculus used to determine the accumulation of a quantity along a specific path within a vector field. This concept has various applications in science, particularly in physics and engineering, especially in calculating the work done by a force acting on an object moving along a certain trajectory. This study aims to examine the application of line integrals in vector fields for calculating the work of a force and to analyze the relationship between a particle’s path and the resulting work. The research method employed is a qualitative approach with mathematical analytical study through theoretical review and calculation of line integrals in two-dimensional vector fields. The analysis process involves defining the vector field function representing the force, parameterizing the particle’s path, and evaluating the line integral to obtain the resulting work. The results show that the work done by a force can be determined through the evaluation of a line integral along the path taken by the particle. Furthermore, the analysis of the vector field indicates that the field is conservative, meaning that the work depends only on the initial and final points of the displacement, not on the shape of the path taken. The visualization of the vector field, particle trajectory graphs, and calculation tables helps provide a clearer understanding of the application of line integrals in analyzing work. Therefore, the concept of line integrals in vector fields can be used as an effective mathematical approach to explain the relationship between force and displacement in a physical system.
