Abstract

This paper introduces an enhanced IS-LM business cycle model by integrating control parameters using the Pontiyagin Maximum Principle Method, aiming to maximize income within economic cycles. It develops a dynamic model incorporating import and consumption rates as controls, showcasing their impact on economic variables through simulations and analytical methodologies. The results exhibit a significant increase in income by up to 10% through the reduction of interest rates and capital stock. The efficiency of the proposed controls is visually demonstrated, providing a robust validation of the methodology used, aligning with prior research, and offering substantial insights into dynamic business cycle modelling for economic analysis and policy-making.

Abstract

The transportation problem is a problem of distributing goods from several sources to several destinations so as to minimize transportation costs. Solving the transportation problem is needed to determine how many items must be sent from each source to each destination that must be met with minimum shipping costs. The purpose of this research is to examine, investigate, and apply the SS method to the minimum case transportation problem, both balanced and unbalanced. This research method is in the form of literature study and literature review from various sources that are relevant to the research. The results showed that the SS (Sheethalakshmy Srinivasan) method proposed by A. Seethalakshmy and Dr. N. Srinivasan can provide the optimal solution without having to find an initial feasible solution to the transportation problem so as to reduce the calculation time. This method provides an optimal solution for the minimum case transport problem for both balanced and unbalanced cases.

Abstract

The purpose of this research is to design logarithmic teaching materials based on mathematical proof. The subjects in this study were 23 students of SMA 1 Sumberjaya, Majalengka Regency, Indonesia, consisting of 23 students in class X IPA-2. This research is a pre-research of the 4P development design study adapted from the Thiagarajan model, et al. namely: (1) Definition; (2) Design; (3) Development; and (4) deployment. In this study, the stages carried out are limited to stage 3, namely development. The deployment phase will be carried out again later. The method used in this study is qualitative method with several data collection techniques in the form of tests of students' mathematical proving abilities in logarithmic material, interviews, and teaching material validation questionnaires. Based on the results of the study, it showed that teaching materials were in the appropriate category with a very good predicate with a percentage of 88.93% from material experts and in the appropriate category with a good predicate of 85.08% from media experts. The results of the practicality test on students amounted to 82.5% indicating that the teaching materials that have been made have a practicality category with a good predicate.
