INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 8, ISSUE 12, DECEMBER 2019 ISSN 2277-8616 307 IJSTR©2019 www.ijstr.org Morphological Material Analysis Of Affixation In 2013 Curriculum Thematic Teaching Books In Indonesia Guesa Maiwinda, Aninditya Sri Nugraheni Abstract: This article discusses the morphology material in the field of affixation in the integrated thematic textbooks of the 2013 curriculum class V theme II on 'Clean Air for Health'. Many morphology materials in the field of affixation that we often encounter in various reading books, both formal and informal reading books. It's just that the reader doesn't know what affixation is or what is commonly called affix. The purpose of writing this article is to describe the many morphological studies in the field of affixation contained in thematic textbooks made by the government. The use of morphological material in affixation studies includes prefixes, infixes, suffixes, and confixes. This research is a qualitative descriptive study. The data in this study are words that contain elements of affixation in the study of morphology in thematic teaching materials in class V theme II. The results showed that there were many morphological studies in the 2013 V grade II thematic curriculum thematic textbooks.

INTRODUCTION The 2013 curriculum is designed to be able to develop a balance between developing spiritual, cognitive, social, and self-skills in students [1]. In applying the 2013 curriculum, there were several changes made. One of the changes made is related to the use of thematic books / teaching materials. Textbooks must be adapted to the development of science and society. One of the 2013 curriculum books is thematic books / teaching materials. In making and developing thematic teaching materials, of course the government also pays attention to the rules in language, the use of Enhanced Spelling, the use of punctuation and also the role of linguistics which is often referred to as linguistics as well as formulating teaching materials so that teaching materials made can be of quality and easily understood by all parties. Linguistics has a very important role in education. For a teacher, knowledge in language and linguistics is very important. How is it possible for a language teacher to practice language skills if he does not master the language, how is it possible for a teacher to practice writing (writing) skills if he does not master spelling. As a teacher, especially in elementary schools, it is not only necessary to practice language skills, but also to explain the rules of language correctly. It also includes the use of linguistics in teaching including phonology, morphology, syntax, semantics, psycholinguistics and sociolinguistics [2]. The analysis of morphological material on the 2013 curriculum thematic teaching materials aims to determine the extent of morphological material contained in the thematic teaching materials. Then it aims to pay attention to the rules in language, the use of Enhanced Spelling, the use of punctuation, the use of affixes (affixation), and also the role of linguistics which is often referred to as linguistics as well as formulating teaching materials so that teaching materials made can be of high quality and easily understood by all parties. The use of affixation or affix that is not right, can be due to lack of student knowledge about the use of affixation or lack of teacher attention to students. So to overcome this, the government as early as possible to make efforts to reform. It can be seen from the many uses of affixation contained in the 2013 curriculum thematic teaching materials which in general we have encountered many but do not pay attention to their functions. hence, researchers here will explain the affixation section broadly. This study refers to other research related to research on this topic, namely research on morphological analysis studies including conducted by Yulino Indra (2014), Agustina Putri (2017), Lismelinda (2017), Tiara Puspita (2016), Ella Sari (2016) 2016). Based on previous studies, seen more researchers here want to identify the morphological material in the field of affixation contained in thematic teaching materials. The benefits of this research are that teachers and students can easily understand teaching materials in class, making the reader accustomed to using good and correct Indonesian, especially in making works, becoming a reference for teachers when making/developing teaching materials following Indonesian language rules. The use of language (in teaching materials) that follows the rules that are considered standard is the correct or correct rules [3]. The theory used in this study is about affixation and teaching force. Affixation is a bound affix because he cannot stand alone, always side by side with the basic word [4]. Affixation is the topic of the smallest part of morphology [5]. Types of affixation include prefixes, infixes, suffixes, and confixes [6]. In the Indonesian morphological process, there are several types of affixes known as follows [7]: a) Prefixes are affixes that are attached to the basic form (basic words). Prefix is also called prefix or more commonly called prefix. Various prefixes: me, di-, ter-, per-, se, per-, per-, para-, pre-, and so on. b) Infix is an affix attached to the middle of the basic form because it attaches to the middle of the basic word so it is called an insert affix or commonly referred to as an insert. Various kinds of insertions/infixes: -el, -em-, and -er- c) Suffix is an affix that is attached behind the basic form (basic word). Suffixes are the final affix usually called the suffix. Various suffixes / suffixes: -i, -an, -kan, -nya, -wan, - wati, -man, -is, and so on. d) Confixes / simulfixes are a combination of prefixes and suffixes [8]. Both types of affixes are attached together in a basic form on the front and back. In line with this, if related to teaching materials a standard book ————————————————  Guesa Maiwinda, Faculty of Tarbiyah and Education State Islamic University Sunan Kalijaga, Yogyakarta, PH-082283862131.
