Fuzzy delphi method: Issues and challenges
The Fuzzy Delphi Method (FDM) is the modified and enhanced version of the classical Delphi technique. Improvement was made to rectify the imperfection of traditional Delphi Method (DM) that leads to low convergence in retrieving outcomes, loss of important information, and long progress of investigation. Nevertheless, this approach has been employed in various application domains, including humanities, management, business, physical science, and engineering. Furthermore, the literature has exposed numerous key issues in relation to the existing FDM that need to be resolved with regard to the classical DM. Hence, the analysis obtained from the existing literature highlighted two key issues, which were; i) most FDM ignored certain important characteristics of DM, and ii) lack of explanation on how FDM obtained controlled feedback with the lack of iteration process. Additionally, it was observed that there had been lack of comparison between decision outcomes obtained based on FDM and the decision outcomes obtained from the traditional DM.
Defining e-portfolio factor for competency certification using fuzzy delphi method
This study is introducing the e-Portfolio function as a storage, workspace and showcase to support Competency Certification in Indonesia. Thus, the mix-method approach was implemented on determining important elements of e-Portfolio as a storage, workspace and showcase for competency assesment context. The research implemented thematic analysis and Fuzzy Delphi Method to obtain the result. Therefore, 20 experts in certification competency domain were participated in the process. As resulted, this study highlighted the basic role of e-Portfolio consists; workspace, storage and showcase. INTRODUCTION Indonesia as the country with the largest population in the ASEAN region, should be ready to face the free flow of labor both at regional (Economic ASEAN Community) and global (China-Asian Free Trade Agreement) levels (The ASEAN Secretariat, 2015), but the condition of Indonesian workers still showed relatively low competitiveness compared to the ASEAN member countries (Biro Pusat Statistik, 2015; The ASEAN Secretariat, 2015). To raise the competitiveness, Indonesia's government try to improve quality of human resources in Indonesia (Republik Indonesia, 2003, 2012, 2007). The Government set up some policies in objective to improving the quality of Indonesian human resources in national development, set up the system, the structure, organization and guidelines for integrating education and job training and work experience in order job competence recognition awards. (“PerMenakertrans no. 14 tahun 2015,” n.d.; Republik Indonesia, 2006, 2014) In line with the process of increasing the competence of labor in the process of obtaining certification of professional competence in Indonesia, previously performed Portfolio assessment process conducted by the Board of Certification of Profession Competency (Republik Indonesia, 2004) assisted by the Certification Body (Republik Indonesia, 2004), an assessment methods against someone based on those documents. The document is evidence that the professional has had a competency. To ensure that the portfolio held information is correct, then the assessor may verify the portfolio related to documents filed with the competency test participants using four criteria rules of evidence (Valid, First, Latest, Sufficient) (“PerMenakertrans no. 14 tahun 2015,” n.d.) (Republik Indonesia, 2004). However, the assessment portfolio process has a weakness, the portfolio is in paper form, the time for inspection the portfolio required a long time, there is no standard guidence to determine which one evidence must be submitted, it cannot be used to test a unit in an integrated, cannot render the evidence is not written, the reference list or index of the portfolio proposed to be set in advance, the evidence indicated must be current and valid and the election and an explanation of the evidence submitted by the participants competency tests may have an impact the expected results. Based on the issues, e-portfolios can be the one way to solve it, where e-Portfolio as a professional profile in digital form can capture and compare the information on the level of skills and professional competence, potential for development, and career prospects (JISC, 2009; Smith, 1996; Woodbury, Addams, and Neal 2009). Besides e-Portfolio also have broad implications for public tool used by the government where they can be used to describe the services provided by the government, which is a service that is more transparent and more accountable pursuant to Presidential Instruction No. 3 of 2003, O'Brien et al, (O’Brien, Osbaldiston, & Kendall, 2014) stated e-Portfolio is a form of e-government implementation in the development of an entrepreneurial society independently.

Development Strategies for Improving the Services of Tourist Night Markets through Hybrid MCDM Technique
Night market has cultural uniqueness and becomes a must-visit for international visitors. Each night market has its own characteristics and can attract some specific kinds of consumers with particulr preferences. However, against the growing competition from other tourist spots, it is very critical to build the development strategies of night markets. This study explores tourists' preferences and analyzes competitiveness of night markets through the following service value model. The criteria inter-relationship structure is firstly analyzed by establishing the connecting diagram of Interpretive Structural Modeling (ISM), and criteria are classified based on their characteristics by employing the Principal Component Analysis (PCA). Moreover, the Analytic Network Process (ANP) is used to realize the magnitude relationship among the criteria, while the VIKOR (Vlsekriterijumska Optimizacija I Kompromisno Resenje) is adopted to evaluate and resolve the problem of mutual competition among criteria and issues of alternative prioritization. Ultimately, preference differences between night markets for tourists are identified. This study lists the items emphasized by tourists on night markets through applying the multi-criteria decision-making model and incorporates the findings into planning and redesigning of night markets. Lastly, this study is one of handful researches applying quantitative methods to evaluate the characteristics of night markets, and is the only one work using the multicriteria model for evaluation. In other words, it has importance on relative policy application and innovation of research approaches.
