Abstract

This study aims to develop a concept image-based E-LKPD on sequences and series using the ADDIE model.This development research was carried out up to the Development stage, which includes Analysis, Design,and Development. In the analysis stage, learning needs were identified through concept image tests,interviews, and documentation studies. The results of the analysis showed that students still had difficultyin understanding the concepts of sequences and series in depth, differentiating the concepts of sequences andseries, and connecting various mathematical representations. Based on these needs, an E-LKPD was designedthat included problem-oriented activities, pattern exploration, concept construction, concept reflection, andcontextual application. In the development stage, the E-LKPD prototype was compiled and validated bymaterial experts and media experts to assess the feasibility of content, presentation, language, andappearance. The validation results showed that the developed E-LKPD met the valid criteria and was suitablefor use as a supporting teaching material for mathematics learning. The concept image-based E-LKPD isexpected to help students build a better conceptual understanding of sequences and series through theintegration of visual, verbal, numeric, and symbolic representations.

Abstract

Epidemic-type mathematical compartmental models are no longer limited to biological infectious diseases; they are increasingly adapted to behavioral and social contagion phenomena. This study aimed to systematically review the use of SIR, SEIR, SEIRS, and modified compartmental models in infectious disease transmission and social phenomena. A systematic literature review was conducted by screening 24 full-text articles collected from journal databases and publisher repositories from 2020 to 2026. Eighteen primary modelling studies were included in the main synthesis, while six review or guideline articles were used as theoretical and methodological support. Data were extracted on model type, domain, compartments, data source, mathematical analysis, simulation method, software, and major findings. The reviewed infectious disease studies addressed tuberculosis, malaria, COVID-19, and typhus, whereas social-domain studies covered online game addiction, social media addiction (TikTok), online gambling, gambling crime, and impulsive buying. SEIR was the most frequent structure, followed by SEIRS and SIR. Most studies calculated equilibrium points and the basic reproduction number; fewer studies reported sensitivity analysis, parameter calibration, uncertainty analysis, or empirical validation. The findings indicate that compartmental models are flexible analytical tools across biological and social systems, but future studies need stronger reporting transparency, parameter justification, validation, and reproducible simulation procedures.

Abstract

Proses berpikir matematis merupakan kemampuan untuk memahami, menganalisis dan menyelesaikan masalah melalui prosedur yang logis. Proses ini menjadi penting karena meningkatkan analisis, logika, memecahkan masalah, mengembangkan kreativitas, meningkatkan komunikasi ataupun meningkatkan dalam menghadapi tantangan khusunya pada pembuktian prinsip matematika.Tujuan penelitian ini adalah untuk menganalisis kemampuan berpikir matematis mahasiswa pada pembelajaran Analisis Riil. Metode yang akan digunakan dalam pencapaian tujuan penelitian ini deskriptif kualitatif. Teknik pengumpulan data menggunakan tes dan wawancara. Tes yang di maksud pada penelitian ini adalah tes untuk melihat kemampuan berpikir matematis mahasiswa, kemudian untuk wawancara untuk mengetahui menggali secara oral kemampuan berpikir matematis mahasiswa. Hasil penelitian menunjukkan bahwa a) Mahasiswa yang dapat menjawab soal dengan benar melewati tahapan entry, attack, dan review dengan maksimal, b) Mahasiswa yang menjawab sebagian benar melewati masa entry dengan baik, tetapi kurang baik dalam melalui tahapan attack dan review, dan c) Mahasiswa yang menjawab salah semua melewati semua tahapan Mason dengan kurang baik.
