It publishes twice in a year, in April and October. The journal accepts original articles written in English which have not been published and not under consideration to be published in another journal or proceedings. All submitted articles which meet these criteria will be double-blind reviewed by at least two international reviewers before the editor(s) decided to accept or to reject them. We are looking forward to see your contribution in the journal.</p> Universitas Ahmad Dahlan en-US Bulletin of Applied Mathematics and Mathematics Education 2776-1002 <p>Authors who publish with this journal agree to the following terms:</p> <ol type="a"> <li>Authors retain copyright and grant the journal right of first publication with the work simultaneously licensed under a <a href="https://creativecommons.org/licenses/by/3.0/" target="_new">Creative Commons Attribution License </a>that allows others to share the work with an acknowledgement of the work's authorship and initial publication in this journal.</li> <li>Authors are able to enter into separate, additional contractual arrangements for the non-exclusive distribution of the journal's published version of the work (e.g., post it to an institutional repository or publish it in a book), with an acknowledgement of its initial publication in this journal.</li> <li>Authors are permitted and encouraged to post their work online (e.g., in institutional repositories or on their website) prior to and during the submission process, as it can lead to productive exchanges, as well as earlier and greater citation of published work (See <a href="http://opcit.eprints.org/oacitation-biblio.html" target="_new">The Effect of Open Access</a>).</li> </ol> https://journal2.uad.ac.id/index.php/BAMME/article/view/9351 <p>The two-person zero-sum discrete-time feedback linear quadratic dynamic game is considered. A method that provides a saddle-point for the zero-sum discrete dynamic game is developed to derive a necessary and sufficient condition under which the game has a feedback saddle-point solution. Existence solutions, which are described in terms of a sequence of nonnegative definite algebraic Riccati matrices, are constructed. Next, a generalization of such a game to a multi-player case is studied. Using the results in a two-person case, the characterization of a feedback saddle-point solution for the multi-player game is derived.</p> Muhammad Wakhid Musthofa Jacob Engwerda Copyright (c) 2024 Muhammad Wakhid Musthofa, Jacob Engwerda https://creativecommons.org/licenses/by-sa/4.0 2024-06-07 2024-06-07 4 1 1 8 10.12928/bamme.v4i1.9351 https://journal2.uad.ac.id/index.php/BAMME/article/view/10021 <p>This research aims to develop a guidebook for the use of GeoGebra in creating mathematics learning media based on ethnomathematics for university students in mathematics education study program at Pattimura University PSDKU Maluku Barat Daya. The method used in this research is Research and Development (R&amp;D) with 4D model developed by Thiagarajan et al. (1974) which consists of 4 stages, namely Define, Design, Develop and Disseminate. This method and model are very feasible and systematically supports the development of the guidebook. By involving 2 validators, namely material experts and linguists, the draft of the guidebook was then revised and tested on a small limited group. Furthermore, based on descriptive statistical analysis and qualitative descriptive analysis, it can be concluded that the reference book using GeoGebra has been successfully prepared and meets the criteria of valid and effective. In addition, the use of this guidebook can also increase students' knowledge in understanding material related to cartesian coordinates, especially in drawing graphs of linear functions, quadratic functions, polynomials, trigonometric functions, exponent functions, and logarithms.</p> John Nandito Lekitoo Ratnah Kurniati MA Sigit Sugiarto Andy Sunder Keer Dahoklory Michael Inuhan Karolina Rupilele Copyright (c) 2024 John Nandito Lekitoo, Ratnah Kurniati MA, Sigit Sugiarto, Andy Sunder Keer Dahoklory, Michael Inuhan, Karolina Rupilele https://creativecommons.org/licenses/by-sa/4.0 2024-06-07 2024-06-07 4 1 9 18 10.12928/bamme.v4i1.10021
