exercise; pursue hobbies (such as: farming and raising 
pets); participate in PHBI (Commemoration of 
Islamic Holidays); periodic recreation / spiritual 
tourism (such as: travel / pilgrimage guardian); 
fasting sunnah (such as: fasting Monday-Thursday 
and fasting David); follow religious studies (such as: 
Dhuha lectures every Sunday morning, Yasinan / 
mujahadah every Friday night), and perseverance in 
performing worship, both obligatory and sunnah, 
shows better productivity. Not only that, these 
positive activities were also able to improve good 
relations with God and with others, both at work and 
outside of work, such as with family at home. This is 
different from employees who, when experiencing 
stress, instead carry out immoral activities, such as 
alcohol, drugs, cheating, and gambling. 
Various studies of experts as well as preliminary 
findings of the study indicate that employee 
productivity cannot be separated from the issue of 
religiosity. Therefore, researchers assume that 
religiosity plays an important role in increasing 
employee productivity in the steel industry. 
2  LITERATURE REVIEW 
2.1  Religiosity 
Religiosity is a person's religious beliefs based on 
monotheism and how these beliefs have implications 
for everyday life. It is not uncommon for religiosity 
to be interpreted and known by beliefs that are 
practiced by ritual and tend to be good or can also be 
called morally. Therefore, Nashori and Mucharam 
(2007: 237) reiterated that for a Muslim, religiosity 
can be known from how far knowledge, belief, 
implementation and appreciation of Islam. 
In Islam and for a Muslim, religiosity or 
religiosity is not only realized in the form of ritual 
worship, but also actualized in various other 
activities. As a comprehensive system, Islam 
encourages its adherents to be religious as a whole as 
the word of Allah SWT (QS. Al Baqarah: 208), 
namely: "O you who believe, enter into Islam as a 
whole, and do not join in the steps of Shaykh. Surely 
Syaithan is a real enemy to you. " 
Religiosity is related to cognition, namely 
religious knowledge or beliefs that influence what is 
done with attachment or emotional feelings about 
religion and / or behavior, such as: attendance at a 
place of worship, reading scriptures and praying. 
Someone who is said to be religious are those who try 
to understand life and life more deeply than the 
outward boundaries that move in the vertical 
dimension of life and transcend this life. 
Measurement of religiosity can be focused on 
involvement in religion and behavior or on attitudes 
and orientation towards religion (Bastaman, 1995: 
56). 
In this study, what is meant by employee 
religiosity in the steel industry is the behavior of 
Muslim employees that work is an actualization of 
worship carried out regardless of the material by 
promoting effectiveness (on target) and efficiency 
(appropriate). 
2.2  Productivity 
Productivity implies an understanding of economic, 
philosophical, and system concepts. Economic 
concepts, productivity with regard to human business 
or activities to produce goods or services that are 
useful for meeting the needs of human life and society 
in general. Philosophical concepts, productivity 
contains a view of life and a mental attitude that 
always strives to improve the quality of life where the 
situation today must be better than yesterday and the 
quality of life of tomorrow must be better than today. 
This gives encouragement to try to develop 
themselves. The system concept, productivity 
provides a guideline for thinking that achieving a goal 
must have cooperation or integration of the relevant 
elements as a system (Anoraga, 2004: 175). 
In this study, what is meant by the productivity of 
Muslim employees in the steel industry is a mental 
attitude to produce quality work. 
3  METHODOLOGY 
3.1  Research Methods 
The method used in this study is a case study. Study 
methods or case studies are methods that intensively 
study a symptom that occurs in one or several places 
as a whole (Bhattacherjee, 2012: 93). 
Judging from the type of research, this research is 
qualitative research. Qualitative methods are used to 
examine the condition of natural objects (the 
opponent is an experiment) where the researcher as a 
key instrument, data source sampling is done 
purposively and snowball, data collection techniques 
with triangulation (combined), data analysis is 
inductive / qualitative and the research results are 
more stressful meaning rather than generalization 
(Sugiyono, 2011: 15). 
The qualitative method in this study emphasizes 
the researcher to pay attention to the process, the 
researcher as the main instrument of data collection 
and analysis so that researchers are directly involved 
in the field work. The research findings were 
reviewed descriptively and it was hoped that data and
