Inclusive elementary classrooms require instructional approaches that accommodate substantial variation in students’ numeracy readiness, learning characteristics, and support needs. This study examined teachers’ instructional needs and preliminary learner differences as an empirical basis for designing a Differentiation-Based Problem-Based Learning (DIF-PBL) model for inclusive numeracy learning. The study was conducted as a descriptive needs assessment within a broader research and development project. Participants included 20 classroom teachers and special education support teachers from three inclusive elementary schools in Bone Regency, South Sulawesi, Indonesia. Data were collected using a 13-item four-point Likert questionnaire and structured observations of three students representing different learner profiles. Questionnaire data were analyzed using item-level means, standard deviations, and response frequencies, while student observations were treated as illustrative contextual cases. Teachers reported substantial instructional challenges, including disparities in numeracy achievement, difficulty balancing instructional support, limitations in conventional Problem-Based Learning, and practical difficulties in implementing differentiated instruction. The strongest responses concerned the need for an integrated PBL and differentiation model (M = 3.95, SD = 0.22), an operational teacher guide (M = 4.00, SD = 0.00), and the urgency of developing the DIF-PBL model (M = 4.00, SD = 0.00). The findings support several design requirements, including differentiated learning pathways, flexible PBL procedures, Concrete–Pictorial–Abstract learning progression, systematic scaffolding, adaptive assessment, and practical teacher guidance. The findings provide an empirical starting point for subsequent prototype development and validation rather than evidence of model effectiveness.

Inclusive elementary classrooms require instructional approaches that accommodate students with diverse learning characteristics while ensuring equitable opportunities to develop numeracy competencies. Although Problem-Based Learning (PBL) and Differentiated Instruction have individually demonstrated positive educational outcomes, limited studies have translated teachers’ instructional needs into evidence-based design requirements for an integrated instructional model. This study aimed to conduct a comprehensive needs assessment to identify instructional problems, critical root causes, and instructional design requirements that provide the empirical foundation for developing the Differentiation-Based Problem-Based Learning (DIF-PBL) model for inclusive numeracy learning. A mixed-methods convergent parallel design was employed as the initial phase of a Research and Development (R&D) project. Participants included 20 inclusive elementary school teachers who completed a needs assessment questionnaire and three students representing different learner profiles who were involved in initial numeracy observations. Quantitative data were analyzed using descriptive statistics, while qualitative observation data were analyzed descriptively and integrated with quantitative findings through methodological triangulation. The findings revealed four major issues: disparities in students’ numeracy achievement, limitations of conventional PBL in heterogeneous classrooms, practical challenges in implementing differentiated instruction, and a strong consensus regarding the urgency of developing a new instructional model. The analysis identified seven key instructional design requirements: adaptive learning pathways, flexible PBL syntax, Concrete–Pictorial–Abstract (CPA) learning sequences, systematic scaffolding, structured peer tutoring, tiered learning tasks, and adaptive assessment strategies. This study bridges empirical needs assessment and instructional design by translating authentic classroom evidence into evidence-based principles for developing the DIF-PBL model, providing a conceptual and empirical foundation for its subsequent prototype development, validation, and effectiveness evaluation.

Rug abuse is one of the major social issues in Indonesia, particularly in South Sulawesi. This study aims to develop a mathematical model that represents the dynamics of drug addiction in the population and to solve the model numerically using the Adams-Moulton method. The model applied is theSIIHRcompartment model, which segments the population into five groups: susceptible (S), light addict (IR), heavy addict (IB), in rehabilitation (H), and recovered (R). The analysis results indicate that the basic reproduction number푅₀is less than 1, suggesting that drug addiction in the population can be managed. Numerical simulations are conducted using the fifth-orderRunge-Kuttamethod for initial values, followed by theAdams-Bashforth-Moultonmethod as the numerical solution technique. The model demonstrates stability at the drug-free equilibrium point and consistency between the outcomes of mathematical and numerical analysis.

This study aims to obtain a numerical solution of the Susceptible-Exposed-Latent-Recovered (SELR) model with a delay time for diabetes cases among active students of FMIPA UNM. This SELR model is built based on certain assumptions, then an analysis is carried out to determine the stability of the model, and simulations are carried out to predict the incidence rate of diabetes. This study is an applied research, and the method used to obtain a numerical solution of the SELR model is the 4th Order Homotopy Perturbation Method, using secondary data. The results of this study include a numerical solution of the SELR model for diabetes cases with the Homotopy Perturbation Method, which shows that this model can predict the potential spread of diabetes among students.

This study is to build a time-delay SDIR model on the case of student interest in Organizations and Government Internship Programs, analyze the model and conduct a model simulation to predict the level of student interest cases in Organizations. This study is a theoretical and applied study. Analysis of the time-delay SDIR model of the case of student interest in Organizations, while the model simulation uses Maple Software. The population of the study was active students of FMIPA UNM, with a sample size of 1029 students obtained using the Sloving technique. The results of this study are a mathematical model of SDIR on the case of student interest in Organizations which is a system of differential equations. The model analysis provides a value of the free equilibrium point of the case of student interest in Organizations and a stable endemic equilibrium point. The results also found that the basic reproduction number value for cases without a solution would produce R0n = 9.912507841, which means that in social cases where one individual can influence 9-10 people in their environment to hesitate to participate in organizational activities or internship programs, but on the other hand if the case is given a solution, it will produce R0s = 0.2737372211, which means that there is no psychological spread, where each individual does not influence other individuals.

Celebrity worship is a form of almost obsessional participation in which people idolize and even start to “worship” their favorite celebrities. Twitter reveals that in 2021, Indonesia was ranked fourth as the country with the most number of Korean Pop (K-Pop) fans. In this study, we constructed a SEIRS mathematical model of celebrity worship tendency among K-Pop fans (CWKF) because there have not been specific mathematical models built on the problem of celebrity worship tendency among K-Pop fans. The CWKF free equilibrium point (E 0), endemic equilibrium point (E 1), and using the Next Generation Matrix for the Basic Reproduction Number (R 0) are calculated through analysis. Using the Routh-Hurwitz criteria for equilibrium analysis, we found that E 0 is locally asymptotically stable if R 0 < 1, and E 1 is locally asymptotically stable if R 0 > 1. Secondly, we conduct numerical simulations using Maple software, and research data consisting of 204 individuals from various regions in South Sulawesi serves as the basis for this mathematical analysis. The numerical simulation obtained supports the dynamic analysis results that the number of individuals who are K-Pop fans will decrease in the population and disappear within a certain period, even without any special treatment.

Silariang is a form of deviant behavior that is consciously carried out by men and women by taking shortcuts in marriage without getting the blessing of the family. The causes of silariang are not getting parental approval, cash problems, promiscuity, pregnancy out of wedlock. Abbaji ammotere is an alternative solution to improve relationships with family. This research aims to build a SEIR models. This model is divided into four classes, namely the class of people who have the potential to carry out silariang, the class of people who are affected by carrying out silariang, the people who carry out silariang, and the people who return to their parents (Ammotere Abbaji). The data used is primary data obtained by distributing questionnaires to 204 samples which were carried out offline for silariang perpetrators and online for vulnerable and affected communities. The real data results of the SEIR type model produce a basic reproduction number (R0) of 0,20381767, which means that the range class will experience a significant increase in the sense that at any time they will be affected and practice silariang, while for classes that have practiced silariang this will decrease over a certain period of time.
