Primary data and secondary data are used to calculate the WTP value. Primary data were obtained from 62 respondents using Accidental Sampling and key persons. Secondary data were obtained from relevant agencies. Descriptive statistical analysis is used to answer the first aim of this research, in-depth interview is used to the second aim of this research and the Contingent Valuation Method with the Bidding Game technique is used to answer the third aim of this research. The results of the research using questionnaires showed the perception of visitors  to  Taman  Indonesia  Kaya,  respondents  rated  quite  good  and  had  the potential to be developed with an average value of 6.5 out of 10 on all criteria. The results of the Contingent Valuation Method show that there are 90.32% who are willing  to  pay  (Willingness  to  Pay),  with  an  estimated  total  WTP  value  of  Rp396,833,500 per year. All of the community’s willingness (WTP) factors have a significant effect, except for marital status.

Abstract

Environmental degradation is an important issue which is currently can be a threat to sustainable economic development in both developed and developing countries. Research on environmental damage due to economic development actually has been done a lot in the previous research but most of them only uses CO2 emission indicators to measure the level of environmental degradation. This study uses the concept of Ecological Footprint and more specific this study want to analyst Carbon Footprint to see the level of environmental damage. The purpose of this study was to examine the effect of economic growth, population, energy consumption, foreign direct investment (FDI) and crisis economics on Carbon Footprint in ASEAN 8 during the period 2000-2017 and to prove the existence of Environmental Kuznets Curve (EKC) shown by Inverted U-shaped. The method that used in the study is panel data regression with the Random Effect Model. The results showed that the Environmental Kuznets Curve (EKC) hypothesis was proven in ASEAN 8 countries. Population and energy consumption variables have a positive and significant effect on the level of Carbon Footprint, while foreign direct investment has a positive effect and appropiate with Pollution Heaven Hypothesis, but does not significantly affect the Carbon Footprint.

Abstract

In recent years, almost all ASEAN members have experienced an increase in the value of the economic complexity index. This change can be seen in the improved ranking of ASEAN members in the economic complexity index. Growth can be driven by the process of diversification in knowledge to produce goods that are more sophisticated and more complex. The key to growth in economic complexity is relocated activities from less complex sectors to more complex sectors. More complex sectors require more knowledge to produce goods. The purpose of this study is to examine the effect of the internet, prosperity, entrepreneur, market share and total export on economic complexity in 2009-2018 in ASEAN member countries. This study uses secondary data with a panel data of 90 observations. The analytical tool used in this research model is Generalized Least Square. The results in this Study indicate that the internet, entrepreneur, and total export have positive and significant effect on economic complexity. Prosperity and Market share have negative and significant effect on economic complexity.
