speak intensively in the first semester in intensive speaking class, second semester in interpersonal and transactional conversation, and third semester in speaking for general
purposes  class.  In  addition,  other  subjects  which  they  have  joined  in  the  college, support them in speaking.
However, although cohesion is taught from junior high school, the students of English Department still face problem in applying cohesive devices. It was proved by
Sri  Suprapti  2009  who  did  the  research  by  using  the  junior  students  of  English Department of UNNES as the subject. In the research, she concluded that there were
some  cohesive  problems  in  the  investigated  data  both  of  grammatical  cohesion  and lexical cohesion. The problems in the grammatical cohesion could be sub-categorized
into: a wrong use of conjunction; b wrong use of demonstratives; c wrong use of pronominals. Then, the lexical cohesion problems are in forms of a lexical repetition
with irretrievable referents within the texts; b naming: the use of a more specific term subordinate term in place of a more general super-ordinate one.
From the above consideration, it is essential to acknowledge to what extent the third semester students
’ speeches are cohesively produced, especially the unified text, using cohesive devices, and what kinds of devices are found in their speeches.
1.2 Reason for Choosing the Topic
Some reasons why I chose the topi c “Cohesion in Students’ Speeches The Case of the
Third Semester English Language Students of UNNES ” are:
Cohesion is an important element that should be used in speaking. It is needed since  it  can  help  hearer  to  understand  the  text  easily.  The  students  of  English
department  are  expected  to  create  a  cohesive  speaking  because  they  have  learned speaking intensively. Moreover, they also joined paragraph based writing that trained
them to make good paragraph which is cohesive. According to Boardman 2001:36, another characteristic of a good paragraph is cohesion. When a paragraph has cohesion,
all the supporting sentence “stick together” in their support of the topic sentence. The methods of connecting sentences to each other are called cohesive devices.
I consider that cohesion is very important in English students ’ speaking, in this
case, is speech, therefore, I want to know to what extent the third students ’ speeches
are cohesively produced.
1.3 Research Problems
The research problems of this study are: 1.
To  what  extent  are  the  speeches  produced  by  the  third  semester  English language students cohesive?
2. What kinds of cohesive devices are found in their speeches?
1.4 Objectives of the Study
The objective of the study can be stated as follows: 1.
To  identify  whether  the  speeches  produced  by  the  third  semester  English language students are cohesive or not.
2. To describe the kinds of cohesive devices found in their speeches.
1.5 Significance of the Study
This study hopefully will give some significances to the readers. The significances are described as follows:
1. Theoretical significance
The result of the research will provide information about cohesive devices used by the third semester students of English Department of UNNES. Besides that,
the result of the research can be used to be an additional reference for further researchers especially those who are interested in discourse analysis within the
same field. 2.
Practical significance The  research  finding  will  help  students  to  understand  the  role  of  cohesive
devices  in  unified  discourse  and  how  they  structure  a  boundary  of  a  text discourse.
