Abstract
Based on the results of research on government-issued textbooks using the 2013 Curriculum for elementary school education levels, it can be seen that the materials in the book do not describe the integration of one material with other materials from various competencies in different fields of science, although under the same theme or sub-theme.In fact, on the cover page it is labelled "Thematic Books for Integrated Curriculum 2013".The lack of integration of these materials is due to the absence of competency material from certain fields that can become the binding thread and act as a medium of transmission from one competency to another when there is a change of discussion material.On that basis, this article provides an overview of how Bahasa materials can be used as a binder and transmission medium between various materials of competence in different fields of science or subjects.In other words, this article presents the conceptual design of an integrated thematic learning material design model based on the role of language as a fetcher of knowledge.
