According to several studies, different indicators should have equal weight (Esty
et al. 2005, 2006; Barrera-Roldán and Saldıvar-Valdés 2002). Differently-weighted
determination would introduce a subjective component to indice development. For
indicator aggregation, the averaging method was used. Sensitivity analysis was a
measure of how far the composite index had developed that depended on information and assumptions. It was necessary to conduct this analysis due to a lack of
theory in allowing the aggregation of different categories into an index. A change in
weightage was used to observe changes in the composite index. Sensitivity analysis
for uncertainty in weighted selection was used to prevent conflicts in policies.
According to previous research, this study assumed an equal weightage system,
which meant every criterion and sub-criterion was considered equally important.
Then, the indicators were tested in the sensitivity level sustainable index.
Criteria Selection
The framework of ecological sustainability for Tasik Kenyir was a combination and
modification based on the theme indicators of a framework by the United Nations
Commission on Sustainable Development (1996) and the Barometer of Sustainability
(Kunasekaran et al. 2017; IUCN 1996). The "barometer" was divided into four
aspects, namely the environment, management, natural resources and politics.
Reflective
Based on Goldberg (2002), indicators did not cater to scientific demands only, but
must also be seen as a symbol of achievement of the best knowledge or idea.
Therefore, only indicators that described sustainable development were selected.
Availability, Continuity and Trustworthiness
Good development index and application played important roles to ensure that the
data was available. According to Barrera-Roldán and Saldıvar-Valdés (2002), the
availability and trustworthiness of data were very important factors in the methodology stated by Agenda 21 and the Organisation for Economic Cooperation and
Development (OECD). Empirical success depended on the availability of a series of
continuous and significant data. For this study, chosen indicators were depended on
what was available in Tasik Kenyir.
