Abstract

Background: This study aims to analyze the economic feasibility and environmental impact of coastal tourism development using an Environmental Economy approach. The research is grounded in the urgency of promoting sustainable local economic development, particularly in coastal areas that hold high tourism potential but are vulnerable to environmental degradation. Methods: The methods employed include primary and secondary data analysis, in-depth interviews, direct observation, and Environmental Cost and Benefit Analysis. Findings: The findings indicate that the development of the Cemara Sewu Beach tourism area is economically feasible, with a benefit-cost ratio of 1.77 and a net present value (NPV) of IDR 129,611,000. Environmentally, the area demonstrates sufficient carrying capacity, with community-based management identified as a key factor in ensuring sustainability. Conclusion: In conclusion, the project is viable and should be pursued using an environmental economic approach that balances economic gains with ecological conservation. Novelty/Originality of this article: The novelty of this research lies in the integrated application of economic feasibility analysis and environmental carrying capacity assessment as a unified framework for sustainable tourism planning.

Abstract

This study examines the use of NaCl as an activator in the production of activated carbon from Polyethylene terephthalate (PET) waste to overcome environmental problems due to the accumulation of plastic waste that is difficult to decompose. This study aims to examine the effect of NaCl concentration on the iodine adsorption capacity of activated carbon. This type of research is experimental research. The samples used were 15 samples of activated carbon. Data collection methods through laboratory experiments. Data analysis was performed by simple linear regression analysis. The results of the analysis showed that variations in NaCl concentration had a significant effect on iodine adsorption capacity, with an R² value of 0.868 indicating 86.8% of variations in adsorption capacity could be explained by NaCl concentration. A concentration of 1M was considered optimal in balancing effectiveness, production cost, and environmental impact, although higher concentrations resulted in better adsorption capacity. This study concludes that the utilization of PET waste for activated carbon production provides a sustainable solution to plastic pollution, reduces waste while producing high-value products for industrial applications, and contributes to the development of more environmentally friendly and economical activated carbon production methods.
