certain needs and demands. Thus, there is an approach to language learning which is called English for Specific Purposes ESP.
According  to  Hutchinson  and  Waters  1991,  instead  of  a  language product, English for Specific Purposes ESP is an approach to language learning,
which  is  based  on  learner  need.  Furthermore,  the  approach  is  used  to  make  a decision about the content and method which will be used based on the learners’
purposes  in  learning.  Supporting  this  view,  Richards  2001  also  states  that  ESP concerns to make language courses more relevant to learners’ needs. So, basically,
ESP is developed based on why people learn English and what for. From the other point of view, ESP is a movement based on the idea that all
language  teaching  should  be  tailored  to  the  specific  language  use  and  learning needs of certain  groups of learners Johns and Machado in Celce-Murcia, 2001.
In addition, Basturkmen 2008 states that typically, the purpose of ESP is to help language learners to deal successfully with the features of language or to develop
the  competencies  needed  to  function  in  a  discipline,  profession,  or  workplace. Thus,  the  language  features  in  ESP  teaching  will  be  based  on  the  target  needs
which then can be identified by doing needs analysis.
b.   Needs Analysis
In  terms  of  linguistic  deficiency,  needs  are  often  described  as  the difference  between  what  learners  can  presently  do  in  a  language  and  what  they
should  be  able  to  do  Richards,  2001.  While  in  the  language-centred  approach, needs  are  the  ability  to  comprehend  andor  produce  the  linguistic  features  of  the
target situation Hutchinson and Waters, 1991. The target situation itself refers to those learners should complete in their future jobs. So, in ESP context, needs are
language  features  that  learners  should  have  in  order  to  be  able  to  carry  out  their tasks.
In  relation  to  this,  Richards  2001  states  further  that  in  ESP,  learner’s needs are often described in terms of performance or what the learner will be able
to do with the language at the end of a course of study. These should be identified before  determining  the  content  of  any  course  because  different  types  of  learners
will have different language needs. An  attempt  which  is  usually  made  to  discover  learners’  true  needs  is
known  as  needs  analysis  Hutchinson  and  Waters,  1991.  There  are  some procedures  suggested  for  conducting  needs  analysis.  These  are  questionnaires,
surveys, and interviews. According to Richards  2001, there are some purposes of needs analysis
in  language  teaching,  for  example,  finding  out  what  language  skills  a  learner needs in order to perform a particular role, helping determine if an existing course
adequately  addressed  the  needs  of  potential  students,  and  determining  which students  from  a  group  are  most  in  need  of  training  in  particular  language  skills.
Besides, needs analysis is aimed to identify a change of direction that people in a reference group feel is important, identify a gap between what students are able to
do and what they need to be able to do, and collect information about a particular problem learners are experiencing.
In  needs  analysis,  basic  information  that  should  be  gathered  are  target needs  and  learning  needs.  Then,  the  information  about  the  target  situations  must
be taken into consideration also. Hutchinson and Waters 1991 explain that target needs  refer  to  what  the  learner  needs  to  do  in  the  target  situation,  and  learning
needs  are  what  the  learner  needs  to  do  in  order  to  learn.  Meanwhile,  target situations are those that are related to what occasion in which the learner performs
the language. In  relation  to  the  target  needs,  there  are  three  important  things  to  be
considered. They are necessities, lacks, and wants.  Necessities can be defined as what learners have to know so that they can communicate effectively in the target
situation.  This  type  of  need  is  determined  by  the  demand  of  the  target  situation Hutchinson  and  Waters,  1991.  Then,  lacks  are  identified  by  find  out  what
learners  already  know  and  do  not  know  about  the  language  used  in  the  target situations. In other words, lacks refer to the gap between the existing proficiency
of  the  learners  and  the  target  proficiency.  For  the  last  term,  wants  are  what learners  expect  during  their  language  learning  processes  such  as  any  kinds  of
learning activities the learners expect. Beside  the  target  needs,  learning  needs  and  target  situation  analysis  are
also important to be taken into account. Dealing with learning needs, some points which  need  to  be  analyzed  are  the  learners’  learning  background,  the  learners’
interests  and  socio-cultural  background,  and  the  resources  are  available.  The information  about  learning  needs  will  be  used  to  determine  how  the  learning
activities  will  be.  On  the  other  hand,  analysis  of  target  situation  needs  is
concerned with language use Hutchinson and Waters, 1991. The information can be about the content of the area, how, when, and where the language will be used.
In  sum,  information  for  the  needs  analysis  can  be  gathered  from  the learners and those who know the target situation well. Then, the information can
be  used  as  the  consideration  to  determine  what  kind  of  methods  and  materials which are appropriate for the learners.
