Background: The greenhouse effect cause the temperature in earth, one of the main contributor in GHG g emission is carbon dioxide (CO2). In order to reducing GHGs empathize in mitigation can be one of the way. By implementing Carbon capture using Algae, where it considered as the main resource of renewable biofuel in the future and possibly play important role in the mitigation of the greenhouse effect. By utilize the photosynthesis process from algae, it can be used for CO2 sequestration as a great potential to reduce GHS gas. The objectives of this research is to understanding and know the process and benefit on using microalgae as the carbon dioxide capture to mitigate climate change (reducing Green House Gas emission). Method and results: The method use in this literature review, method that firstly discussed is the general description with pro cons of carbon capture technology method also with the background in order to reducing the highest contributor of Green House gas Emission (GHGs) which is Carbon Dioxide (CO2), from this utilizing the natural process method from photosynthesis of microalgae whose need a lot source of CO2 being the most beneficial method, and the end of product create a biomass and that will be helping to reducing the use of fossil fuel. Discussing the photosynthesis system it can be far from light dependent and light independent reaction since both of it is a recycled system. Therefore, implementing carbon dioxide capture using microalgae is very useful. Though there still need improvement in this sector. Conclusion: Carbon capture using Microalgae CO2 sequestration is one of the promising way to mitigate climate change and control environmental pollution is by fixing CO2 in the atmosphere and recovering organics from wastewater.

Nowadays, coffee is one of needs among metropolitan people. This lifestyle impact to increasing waste along coffee production, one of them is coffee ground. Coffee ground has toxic properties to the environment such as caffeine, tannins, and polyphenols. While other chemicals contain on coffee ground are 2.28% nitrogen, 0.06% phosphorus, 0.6% potassium, which means has a good impact to the soil. In existing condition, coffee grNowadays, coffee is one of needs among metropolitan people. This lifestyle impact to increasing waste along coffee production, one of them is coffee ground. Coffee ground has toxic properties to the environment such as caffeine, tannins, and polyphenols. While other chemicals contain on coffee ground are 2.28% nitrogen, 0.06% phosphorus, 0.6% potassium, which means has a good impact to the soil. In existing condition, coffee ground is commonly used to, biodiesel and bioethanol or by direct used to the soil. The processing of coffee ground to be liquid organic fertilizer by using bio-activator are considered to substitute the direct used, it will improve the quality of soil. Objectives: The objective of this research is to study of liquid fertilizer from coffee ground, whether comply or not to the standard regulation Ministerial Decree of Agriculture of the Republic of Indonesia Number 261/2019. Method and results: This research use a coffee ground from arabica and robusta coffee and applied 2(two) different dilution by repeated 2x2 on one time by using EM4 as bio-activator. The pH and temperature for 4 experiment measured daily and has an average on 4.8 and 31-degree celcius for 10 days. Nitrogen, Phosphorus, and phosphor measured in the end of experiment has average results on 0.18, 0.17, 0.04, sequentially. Conclusion: The result for chemical parameter; Nitrogen, Phosphorus, and phosphor has not comply to the standard of liquid organic fertilizer by Indonesia Government.ound is commonly used to, biodiesel and bioethanol or by direct used to the soil.

As in the current topic of discussion, namely climate change, where long-term climate change is one of the major environmental concerns. If we look ahead to what is happening in our surroundings, both in terms of weather and temperature, as well as the water we consume, we will notice changes over time. Higher wildfires have resulted from these changes, which have resulted in losses to living creatures on Earth, ranging from increased heat, drought, and insect outbreaks, all linked to climate change. Additional worries include dwindling water supplies, lower agricultural yields, heat-related health effects in cities, and coastal flooding and erosion. As a result, it provides renewable energy that can help mitigate the worst effects of climate change. Objectives: When discussing climate change, we are addressing alterations in weather patterns. Climate change denotes a protracted modification in climate conditions extending over decades, or even longer periods. It emerges as a consequence of global warming, which ensues from both natural phenomena such as fluctuations in solar radiation, volcanic activities, or intrinsic variability within the climate system, and anthropogenic factors including alterations in atmospheric composition or land use. Climate change is contingent upon meteorological variables such as temperature, humidity, wind patterns, precipitation, drought occurrences, aridity levels, and solar radiation impacting the Earth. Method and results: The sources utilized for this composition encompass articles and journals sourced from online social media platforms, alongside a comprehensive review of articles and journals published by international and national agencies, focusing on pertinent issues related to the subject matter. Renewable energy emerges as a formidable tool in combatting climate change, exhibiting promising potential for success. Conclusion: After we investigate and learn about renewable energy in order to discuss the impact of climate change, we can learn about the advantages it offers, such as the advantages of using renewable energy in the environmental and economic sectors, such as generating energy that produces no greenhouse gas emissions from fossil firing and reduces some types of air pollution, as well as the advantages of diversifying energy supply and reducing reliance on imported firing.

Study of Social Carrying Capacity in The Development of Tanjung Lesung as a Sustainable Tourist Destination

Waste problems in Indonesia has reached a critical point that is contaminating many aspects in community. Poor waste management in land have an impact in water pollutions, rivers, and toward the ocean. This rivers and oceans pollution are become the spotlights for the world and the government. As a part of education community in West Java, President University has an important role to educati and find solutions relate with this issues, one of them is to implement Thidharma in the form of social empowerment in Jatireja Village. This environmental education activities was sharing knowledge about plastic waste treatment and management that can be conducted in household scale, and to encourage behavioral change and awareness among communities. Creative product of eco-brick was also implemented tas a part of waste utilization to make valueable product. Environmental education are needed to improve community awareness on plastic waste in Indonesia, especially in West Java.
