infinitive in a sentence which causes them to choose option B call to as the incorrect item in question 5. In the other side, the choice of option B call to for question 5
is also a sign that the students have known the rule of
have
causative which
have
is followed by infinitive.
b. Misordering
Misordering is the other error type that students did in question 4. Although most  of  students  had  answered  the  question  corretly,  there  were  five  students  who
answered  option  A  always  as  the  incorrect  word  in  the  sentence.  Here  is  the question for number 4 Part A:
Question 4: Romantic movies always have her cry. A        B         C
The  word
always
in  the  sentence  describes  habitual  activity.  This  is  the reason  why  always  is  put  between  the  subject  and  the  causative  verb.  Nonetheless,
some of students might think that
always
in this sentence is the incorrect word for the question  4.  It  is  probably  because
always
also  can  be  used  in  present  or  past progressive  for  special  circumstances,  such  as  expression  or  anger  and  complaint
Azar,  1999:  30.  In  this  case,  students  might  consider  the  presence  of  be
arewere
before the word
always
in the sentence, thus influencing them to choose option A. Overall, the result of Part  A in  the test  shows that  most of  the students  have
understood the active-form  of causatives.  On the contrary, some of the results  show that  the  students  still  have  some  mistakes  in  differentiating  the  differences  of
causative’s function and meaning.
2. Students’ Errors in Part B
Part  B  contains  of  six  questions;  6,  7,  8,  9,  10,  11,  of  active causative  sentences.  Here,  the  students  are  instructed  to  change  the  active  sentence
into passive causative  form. The purpose of the  six questions  is  to  find out  how far the students’ comprehension about passive causative form.
In order to sum up the result of test in Part B, some steps were taken by the researcher to make the analysis better. All of error types that have been explained in
Chapter III are found out in each question. The following table shows the number of each error.

From  the  table  above,  misformation  is  the  most  common  mistake  with  the highest  number of  error  in  Part B. Then, it is  followed with  omission as  the second
common mistake. Next, misordering is the third common mistake and addition error
has the lowest number compared to others. In addition to those four types of error, the researcher  also  found  out  that  some  students  did  some  combination  of  errors  in
several  questions.  This  combination  of  errors  will  be  explained  further  later.  The number of unanswered questions is not counted.
a. Misformation
There are several mistakes that can be categorized as misformation, the wrong use of morpheme or structure. First is the change of
have
into
get
of causative verbs or otherwise in the answer. For example:
Question 9  : We need to have someone check out our computer for viruses.
SA : We need to get our computer checked out for viruses.
Question 7  : Though Bruno refused at first, we got him to paint our house last year.
SA : Though Bruno refused at first, we had our house painted
last year. It is indeed that
get
and
have
causatives have some similarities. First, both of them  have  a  same  structure  in  passive  which  is:  [
Subjcauser+   haveget+ complement +  past participle + by  objcausee
] Stefanowitsch, 2001: 201. Second, the  semantic  meaning  of  passive  causatives  of
get
and
have
when  it  comes  to  the absence  of  the  causer  has  no  difference  Celce-Murcia,  Marianne  and  Larsen
Freeman, 1999:  653.  It  happens  when  the speaker does not  know who is  doing the job. According to the fact that
get
and
have
causatives share some things in common, the  students  might  think  that  it  will  not  affect  the  result  if
get
is  changed  into
have
causatives and otherwise.
Semantically, when it comes to a known causer in Question 9,
get
and
have
causatives  will  cause  different  meaning.  Although  the  causee  will  bring  about  the same effect, the process that the causee will come through is different. Stefanowitsch
explains  that the causee  in
have
causative sentence shows no resistance at  all in  the causing event 2001: 204. It is because the service frame connecting the causee and
causer causes the causer to have less effort for affecting the causee. In the other hand,
get
causative  gives  a  sense  that  some  difficulties  are  involved  Celce-Murcia, Marianne  and  Larsen  Freeman,  1999:  653.  The  causee  needs  to  be  convinced  into
doing the causer’s intended action Stefanowitsch, 2001: 205. As a result in question 9,  it  will  lose  the  sense  of  persuading  Bruno  if  the  students  changed  the  sentence
with
had
causative. The next misformation error is the change from active causative sentence into
regular passive sentence. Take a look at these examples: Question 7  : Though Bruno refused at first, we got him to paint our house
last year. SA
: Bruno was got to paint our house last year. Question 9   : We need to have someone check out our computer for
viruses. SA
: Someone is needed to check out our computer for viruses. Students’ answers in both examples above seem to maintain the grammar of
the sentences;  past  tense and simple present  tense. However, there are two mistakes done  in  both  questions  which  are:  first,  they  failed  to  recognize  the  causer  and  the
causee; and second, they failed to change the sentence into a correct passive causative form.
In  question  7,  the  student  seemed  to  be  influenced  by  the  rules  of  regular passive voice. This might be the cause why the students added
was
as the be before
got
. This error is also similar with the student’s answer in question 9. In  the  other  side,  the  students  decided  to  put
Bruno
as  the  subject  for  the passive sentence because
him
in the question is put after the verb that can be a sign as the  object  of  the  active  sentence.  The  students  seemed  to  notice  the  rule  of  regular
passive voice where: one, the form of be is added before past participle of a transitive verb  Zandvoort,  1969:  54;  and  two,  the  subject  of  a  passive  sentence  may
correspond  to  the  direct  object  of  active  sentence  Zandvoort,  1969:  56.  This problem  is  similar  with  question  9  where  the  students  contemplated
need
as  the main verb,
someone
as the object, and
to check out our computer for viruses
as the to- infinitive  clause.  The  omission  of
have
in  the  sentence  is  probably  because  the student thought
need
as the main verb for the sentence. Next,  the  students  also  did  some  errors  in  changing  active  causative  of
have
into passive form in modal tense. The example is in question 9. Question 9  : We need to have someone check out our computer for
viruses. SA
: The computer have to be checked by someone. In  the  example  above,  there  are  two  types  of  error:  misformation  and
omission.  Misformation  error  in  that  answer  is  the  change  in  the  verb  into
have
as modal. The reason why student omitted
need to have
and changed it into
have
modal probably was because of the meaning of
need
itself. Based on the meaning in Oxford Dictionary,
need
has  the  meaning  of:  to  show  what  you  have  to  do.  Due  to  this
