material and learning independently without the help 
of a facilitator. 
Preparation of problem based learning based 
learning modules has begun with previous research. 
From the results of previous studies it has been 
produced problem based learning modules with 
content material, language and design that are valid 
for use by students in taxation subjects. By 
presenting the problem based learning module, 
students are expected to be able to solve whatever 
problems they face. 
2  THEORICAL FRAMEWORK 
a. Learning Module 
Modules are a set of teaching materials that are 
presented systematically so that users can learn 
independently or without a facilitator / teacher. 
Thus, a module can be used as teaching material 
instead of the teacher's function. The teacher has the 
function of explaining material with sound. A 
module must be able to explain material with 
communicative language for students according to 
their level of knowledge and age. Modules are a way 
of organizing subject matter that takes into account 
the function of education. The strategy of organizing 
learning material contains squencing which refers to 
the making of the sequence of presentation of 
subject matter, and synthesizing which refers to 
efforts to show students the relationship between 
facts, concepts, procedures and principles contained 
in the learning material. To design learning material 
capability categories that can be learned by students, 
namely verbal information, intellectual skills, 
cognitive strategies, attitudes, and motor skills. The 
strategy of organizing learning material consists of 
three stages of the thinking process, namely the 
formation of concepts, interpretation of concepts, 
and application of principles (Santyasa: 2009). 
According to Sanjaya (2010: 332-333), the 
purpose of using modules in the learning process is 
as follows; (a) Increasing the effectiveness and 
efficiency of achieving educational and teaching 
goals, (b) Encouraging students to be more active in 
independent learning, (c) So that the learning 
process does not rely too much on the teacher, 
meaning that there are or not teachers ) Learners can 
find out the results of self-learning in an advanced 
manner, (e) Learners can know the results of their 
own learning on an ongoing basis, and will know 
where their own weaknesses are. 
According to the Ministry of National Education 
(2008b: 3-4) a module can be said to be good and 
interesting if there are characteristics as follows; (a) 
Self Instructional, that is through the module, 
someone or participant learns to be able to teach 
themselves, not dependent on other parties, (b) Self 
Contained, that is, all learning material from one 
competency unit or sub-competency studied is 
contained in one module as a whole The aim is to 
provide the opportunity for learners to learn the 
learning material that is complete, because the 
material is packaged into one whole unit, (c) Stand 
Alone (stand alone) ie the module developed is not 
dependent on other media or does not have to be 
used together with other learning media, (d) 
Adaptive modules should have high adaptive power 
to the development of science and technology, (e) 
User Friendly; the module should be friendly with 
the wearer. Information that appears is helpful and 
friendly to the wearer, including the ease of the user 
in responding, accessing as desired. The use of 
language that is simple, easy to understand and uses 
general terms. 
 
b. Problem Based Learning 
The problem based learning (PBL) learning model 
known as the problem-based learning model is a 
learning model that uses real problems encountered 
in the environment as a basis for gaining knowledge 
and concepts through critical thinking skills and 
solving problems. The application of the PBL model 
can help create learning conditions that originally 
only transfer information from lecturers to students 
to the learning process which emphasizes 
constructing knowledge based on understanding and 
experience gained both individually and in groups. 
The problems raised in PBL are real problems in the 
field. 
PBL is a learning method that uses problems as a 
first step in collecting and integrating new 
knowledge. According to Hmelo-Silver & Barrows 
in Fakhriyah (2014) states that the problems raised 
in PBL learning do not have a single answer, 
meaning that students must be involved in 
exploration with several solution paths. 
Problem Based Learning learning model shapes 
students' thinking abilities that are truly optimized 
and developed to be able to solve real problems. 
Based on Trianto's opinion (2010: 90) said that 
"Problem based learning model is a learning model 
that is based on the many problems that require 
authentic investigation, namely investigation that 
requires real solutions to real problems". 
Problem Based Learning learning has a purpose 
in its application in the learning process. As for 
Suyanto and Jihad (2013:154) argues that: Problem-
based learning is designed to (a) help students 
develop thinking skills and problem solving skills, 
(b) learn the role of adults authentic, and (c) 
becoming independent learners. The aim of using 
this model is to provide students with the basic
