Research results from Agsarini&Wiguna (2015) [3] ; Huda &Wibowo (2013) [21]; Omran et al. (2012) [22], concludes that the performance of a construction project is said to be good and can give satisfaction to the project owner if the project is successful in three things: low cost, high quality and timely completion. The result study of Sumaga (2013) [23] and Idrus&Sodangi (2011) [24] concluded that project construction products and contractor service quality can satisfy project owners.   [5] and Devia& Huda (2012) [25] recommend the satisfaction of the project owner if the project is carried out with care for the environment (green construction). Wieke et al. (2012) [4] in his study concluded that simultaneously and partially the occupational health and safety work factors in the implementation of a project can provide satisfaction to the project owner.   [22], consists of indicators: (a) cost of construction works (X11), (b) time of execution of work (X12) and (c) quality of work (X13). 2) Project Products (X2): is the end result of the development process from planning, engineering, auction and construction of construction projects undertaken by the contractor in accordance with the contract of work agreed upon by each party. This construction project product variable is a global dimension and has at least 7 indicator elements adopted from Sumaga (2013) [23] and Idrus&Sodangi (2011) [24], which consists of indicators: (a) performance, (X21), (b) durability (X22), (c) privileges (X23), (d) reliability, (X24), (e) consistency (X25), (f) austhetic (X26) and (g) conformance (X27) 3) Project Services (X3): is the ability of construction service companies to provide services to users of project owners in all aspects, whether written or implied, in morally or materially. The service variable of the popular service concept construction service concept, ServQual stated that the service quality has 9 dimensions (indicator), which is adopted from Parasuraman in Sumaga (2013) [23] and Idrus&Sodangi (2011) [24], which consists of indicators:

D. Data Analysis Technique and Model Test
Descriptive analysis is used to describe the characteristics of respondents and also the responses of respondents. Descriptive analysis is done with the help of computer software SPSS. Similarly, validity test and tool reliability. The measuring tool is valid if the Product Moment correlation coefficient between the item score and the total score is significant (p-value / sig value <α = 0.05). Reliability testing is done by calculating Alpha Cronbach (α) value, if Cronbach Alpha value (α) is greater than 0.60 then research data is considered good enough and reliable to be used as input in data analysis process to test the research hypothesis (Maholtra, 2004) [26]. The results obtained that the value of cornbach alpha from each research variable> 0,6. This means that each research variable has met the requirements of cornbach alpha value, so it can be concluded that all variables have a high level of internal consistency reliability. Similarly, based on the results obtained that the value of composite reliability of all research variables> 0,7. These results indicate that each variable has met the composite reliability so it can be concluded that the overall variable has a high level of internal consistency reliability.
The model analysis used in this research is Structural Equation Modeling (SEM) with the help of SmartPLS software. The results of the model analysis can be seen in Figure 2 and Figure 3. Figure 2 shows that the loading factor estimation result is the coefficient generated from the evaluation of confirmatory factor analysis for the measurement model. Factor loading is used to assess the suitability, conformity or unidimensionality of the dimensions in forming a factor. The estimated load factor values are obtained together with the result of the loading factor estimation for each factor variable of the indicators. Figure 2 also shows the path coefficient value between the latent variables. Figure 3 shows the amount of t-value that will be used as a reference for hypothesis analysis. The value of coefficient and t-value can be seen in Table 2.   Hypothesis testing is done by comparing t-count value of each latent variable with t-table (1,96), that is said significant if t-value latent variable is bigger than t-table (t-value > 1,96). Table 2 shows that the t-value of all variables> 1.96. Meaning all variables: Project performance (X1), Project products (X2), Project services (X3), Green construction (X4) and Work Safety &Health (X5) are stated to have a positive and significant impact on project owner satisfaction (customer). The contribution of independent variable (X1 to X5) to project owner satisfaction (Y) is 97,53%.

Source: SmartPLS Results
Based on the data presented in Table 3, it can be seen that the R-Square value for the customer satisfaction of construction (project owner) is 0.9753. These results explain that the percentage of owner satisfaction can be explained by the research variable of 97.53 percent. While the remaining 2.47 percent is explained by other variables.

III. RESULT AND DISCUSSION Effect of Project Performance:
The project performance is the ability of the contractor to carry out construction work in accordance with the construction work contract. Project performance consists of cost, time and quality indicators. If the lower the project cost, the faster the implementation time and the better quality of the work, the better the project performance and the more satisfying the project owner. The results show that project performance has a positive and significant effect on project owner satisfaction. The findings of this study support the results research of :Agsarini&Wiguna (2015) [3], Huda &Wibowo (2013) [21]; Omran et al., (2012) [22].

Effect of Project Product:
The project product is the end result of the development process from planning, engineering, auction and construction of construction projects undertaken by the contractor. The project product consists of aspects; performance, durability, privilege, reliability, consistency, austhetic and conformance. The results show that the project product has a positive and significant effect on the satisfaction of the project owner. This means that the higher the value of project products, project owner satisfaction will be higher. The findings of this study support the results research of :Sumaga (2013) [23] and Idrus&Sodangi (2011) [24].

Effect of Project Services:
The project services are the ability of contractor companies to provide services to project owners in all aspects. Project service variables conform to the popular service quality concept. ServQual states that service quality has indicators that consist of: reliability, responsiveness, assurance, empathy, tangible, understanding, competence, credibility and communication. The results of this study indicate that project services have a positive and significant impact on project owner satisfaction. This means that the higher the level of project services, the project owner's satisfaction will increase. The findings of this study support the Sumaga study (2013) [23] and Idrus&Sodangi (2011) [24].

Effect of Green Constructionl:
The green construction is the technology and techniques used by contractors in the construction of construction projects oriented to the project cycle by considering energy, pollution, water, air, materials, equipment that have an impact or risk to the environment. Green construction aspects of the construction project is a global issue and has at least five elements of the indicator consisting of indicators: technology, project cycle, energy saving, pollution, material and efficiency. The results showed that green consruction gave positive and significant influence to project owner's satisfaction. This means that the more concerned the contractor to the project environment, the project owner's satisfaction is increasing. The findings of this study support the results of a study by Colliver et al. (2009) [7];   [5] and based on research by Devia& Huda (2012) [25].
Effect of Health& Safety Works : The involvement and active role of the management of contractor companies in formulating programs, shaping culture and realizing kelamatan and occupational health in the construction project environment, accompanied by high commitment to realize the health and safety of project environment during the project. This construction and health & safety works variable is a contractor's competency dimension consisting of 5 indicators elements, namely: top management commitment, rules and procedures, communication, worker competence, worker involvement and work environment. The results showed that health and safety work have positive and significant impact to the project owner's satisfaction. This finding is consistent with the results of research by Wieke et al. (2012) [4] and Huda &Wibowo (2013) [21]. The better the contractor's health and safety management the more satisfying the project owner.
