Abstract. In order to support Indonesian Government priority sector to build toll maritime in conjunction to connect "nusantara" as an archipelago country, and also to develop the frontier area of Indonesia, the existence of a port should get more in attention as the gate of Indonesia. A port has significant role in changing of transport mode and at the end as catalyst of economic growth. An important thing from pre-feasibility studies is the priority factor will clearly shown wheather it is good or fair. As a supporting to service passenger moving, container, general cargo and also bulk, a port is necessary to have an excellent design and planning. A pre-feasibility study is required to obtain a scientific basis based on value of interest and the necessity of the region. A pre-feasibility study in this paper aims to identify potential support of the region and giving priority location of development of new port in Minahasa Utara regarding to spatial, government issues, transportation aspect, regional economics, environmental aspect and technical aspect consideration. Experimental Method used are qualitative and quantitative, going through to the data obtained and supported by interview on the spot as well as questionnaire surveys. Result of this paper showing that there are 5 locations suitable with the requirements. Based on the level of priority, high (Kema, Likupang), moderate (Linuhu, Kahuku) and low (Gangga 1).
The process towards sustainability is indeed very complicated, given the increasing need of the population for infrastructure to support human activities. The objective of the study is to analyze the influence of environmental factors and their awful effects on infrastructure projects with sustainable construction models in special economic zones. The methodology used are mixed methods, combination of quantitative and qualitative approaches with the total respondent are 80 persons. The respondents involved are divided by company/institution, company’s qualifications, and stakeholders. The first validity shows that all factors have a value above 0.5, by using Fornell Lacker Criterion, it is found that the CDV value met the requirements from all variables involved. The validation was calculated by a cross-loading method called discriminant validity. After validity, it is continued to obtain model fit value and the final model fit is 0.568 means good model. The NFI value released was 56.8%. It means that the declared model was good enough to be implemented within sustainability in SEZs. This result supported the previous research, which stated that a sustainable construction model using a multi-criteria approach is a good model choice for the development of a sustainable construction model.
