Abstract

The increase in population certainly greatly affects the amount of existing energy consumption. Based on data taken by the Indonesia Energy Outlook 2019, in 2018 Indonesia has a total final energy consumption (not considering conventional energy) of around 40% of the energy used for the transportation sector, then 36% for industry, 16% for households, commercial and other sectors respectively 6% and 2% respectively. Then, in 2019 the total final energy consumption was 989.9 million Barrels of Oil Equivalent. Then the use of fossil energy has an impact on sustainable life because fossil energy is one of the contributors to carbon emissions on earth. The increase in emissions has an impact on the increase in GHS that has been felt by the earth, namely, the occurrence of very drastic climate changes, as well as affecting temperature rises of up to 3∘C. For this reason, it is necessary to have the potential for renewable energy by utilizing solar energy, namely the process of converting energy produced by solar radiation into electrical energy and efficient use of this energy using smart buildings.. Objectives: The aims of the journal is to know another potential energy sourced to reduce the fossil fuel uses. Method and results: Literature review.

Abstract

Background: Water is an important component for living things on earth, so water cannot be separated from human life. This is because the human component consists of 70% water in it. The increase in population and polluted water sources has caused humans to experience a clean water crisis, thereby hampering human socioeconomic life on earth. Findings: Considering that Indonesia has a fairly high rainfall, namely 2,702 mm3 per year, and has polluted water sources and a large sea area, the innovative idea of using rainwater harvesting and reverse osmosis is a solution to overcome problems and be able to overcome the risk of a clean water crisis in the future. front. Discussing the clean water crisis in Indonesia, the area that has this problem is one of the DKI Jakarta areas, namely, Muara Angke, Pluit, and North Jakarta. Methods: In writing this idea, systematic literature reviews and article reviews were used. The systematic method of the literature review is collecting metadata obtained according to the journal database via https://scholar.google.com/ and visualizing it using VOSviewer. This is intended to show research trends regarding clean water technology. Conclusion: Three blocks have a water shortage crisis, namely the Waste Block, the Eceng Block, and the Empang Block. The scarcity of clean water in this area is caused by illegal land issues which makes it difficult to obtain permits for piping systems from the PDAM and the contamination of springs due to the influence of geographical location. The implementation of this technology is considered quite simple in the community so it can be a solution to the clean water crisis problem.Of course, the treated water is expected to meet the parameters of clean water, namely the Ministry of Health Regulation Number 32 of 2017 concerning sanitation water and the Ministry of Health Regulation Number 492 of 2010 concerning drinking water quality standards. So that the water can be utilized by the people of Indonesia.

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.
