textbooks to guide them in giving subject matter.
For students, textbooks are important learning
materials for understanding the subject delivered by
the teacher. Because of this important function, the
choice of words contained in the textbook must be in
accordance with the student's level so that the
vocabulary that has been learned can support the
understanding of the material at the next level. Very
important to present classifying in word formation
patterns that should appear in Indonesian textbooks.
Word formation can be done through several
processes, 1) merging words, 2) derivation of zero,
3) affixation, and 4) other forms of derivation. Word
formation that is done by affixation produces
derivative words. Affixation is a productive process
in Indonesian language. Affixation is the addition of
affixes, either prefixes, suffixes, confixes, or infixes
to the primary base, secondary base, and tertiary
base (Badan Bahasa, 2017: 118). Affixation,
according to the Indonesian Language Standard
Grammar, is carried out by four components of
affixes, namely prefix, suffix, confix, and infix.
Matthews stated that there are five types of affixes,
namely prefix, suffix, infix, circumfix, and superfix
(1997: 11). The modern linguist Katamba claimed
that there are three types of affixes, namely prefix,
suffix, and infix (1994: 44). However, not all types
of affixes that exist in the languages of the world are
found in Indonesian, for example, the circumfix
type.
Theaffixed words research done by Grangé,
Philippe (2013)discusses free forms and bound
forms in Indonesian. Grange found 72 combinations
of free forms and bound forms. All bound forms are
not classified into simple or complex forms.
However, we can easily sort out that an affixed word
that contains more than two bound forms is a form
that can be categorized as complex rather than a free
form that only gets one bound form.
2 METODOLOGY
The focus of this study is to discuss combined
affixed vocabulary with more than two affixes. The
corpus of this study is the Indonesian Language
textbooks of grade VII, grade VIII, and grade IX.
The study was conducted using a qualitative
approach and content analysis method, while the
design of the study is combined affixed vocabulary
with more than two affixes. Creswell (2009) stated
that qualitative inquirers use theory in their studies
in several ways. This research also belongs to
descriptive study since it just collected and analyzed
the combined affixed vocabulary with more than two
affixes in Indonesian Language textbooks. The
subjects of the study are photographs, art objects,
videotapes, or any forms of sound (Creswell, 2009).
Here the researchers use textsfrom the Indonesian
Language textbooks of class VII, class VIII, and
class IX. Data refers to a collection of organized
information, usually the result of experience,
observation, and experiment. These may consist of
numbers, words, or images, particularly as
measurements or observations of a set of variables
(Yin, 2011). The data in this study was collected
using the following steps: first, researchers chose the
textbook. Second, the researchers described and
listed all the words containing combined affixed
vocabulary with more than two affixes in each class.
Third, the researchers described word formation
pattern. Fourth, the researchers compared the data of
each class. Fifth, the reseacher proposed the
distribution of forms of combined affixes in each
class.
3 RESULT
The results show that there are 12 forms of complex
affixes in Indonesian Language textbooks ofgrade
VII, VIII, and IX. These combined affixes have
more than two affixes so that in their formation
patterns they also go through several stages.
