Background: Air pollution is an issue that has received a lot of attention in the past year, especially in DKI Jakarta. Economic growth after the pandemic has driven high community activity. High community activity drives high energy use. Findings: Through this article, we can find out what sources contribute to urban air pollution and what and how to determine air quality. With high levels of air pollution greatly affecting biodiversity and ecosystems, we can find out the impact and influence on these ecosystems. So we have to find a way out to minimize pollution and maintain the sustainability of urban ecosystems. Methods: This study uses a qualitative approach with a literature study method. The literature study method is a series of activities related to the method of collecting library data, reading and recording, and processing research materials. This method aims to examine various theories that are relevant to the topic being studied as reference material in the analysis and discussion of research results. The literature includes journals, academic publications, and publications by institutions. Conclusion: High human activity drives environmental damage, more than 56.7% of the population is in urban areas. The main characteristics of urban ecosystems include high human population density, intensive land use for settlements, industry, and transportation, and the presence of urban infrastructure such as roads, high-rise buildings, and wastewater systems. Indicators for air quality are the Air Quality Index (IKU) and the Air Pollution Standard Index (ISPU). NOx and ammonia are pollutants that can settle in water bodies, where they contribute to eutrophication. O3 can interfere with the photosynthetic function of plants which eventually causes the plants to not grow and die. Sulfur dioxide and Nitrogen cause "acid rain", thereby increasing acidity which has a negative impact on flora and fauna. Ultimately, acidification affects the ability of ecosystems to provide "ecosystem services". Air pollution factors are the seasonal cycle, community activities for illegal burning and from mobile and stationary sources. Transportation is the first order contributor to poor air in cities. Climate cycles such as differences in wind direction and speed support the accumulation of pollutants which cause high levels of pollution. In DKI Jakarta, the loss of sensitive species that inhabit water channels and also butterflies that are bioindicators of contaminated air

Background: Emperor penguins are one of the species that their life a affects by climate change. They are part of the ecosystem. As a human, we need to know about the condition of the other living things as the effects of this climate change. This journal review wants to prove that the life of emperor penguins are in danger from any aspect because of climate change. Based on a study, the researcher tries to protect the penguins and does several methods to protect them. The researcher also uses the future climate projections to know the condition in the future. Some of the research used the thermal effects test, and observe the model habitat suitability. If the global emissions continue to increase, there is look like no future for emperor penguins. We need to know that every little thing of our action towards this climate change affects the other living things. Therefore, as a human, we need to be more aware of what happens around us. This research objective is to explore more about how climate change affects the emperor penguins' life and why we should care about it. Methods: This research used the literature review method. Two concept approaches were used in this journal review. Findings: The first is about the habitat, life cycle, and how the emperor penguins lived. The second is about the impact and what changes in their life. The result showed that there is a change in the life of emperor penguins, and their existence is endangered due to climate change effects. Conclusion: Emperor penguin is a part of our ecosystem. As a part of this earth, we need to know what is going on around us. We need to know that not only our life that affects by climate change but also the other living things. We could know what kind of actions that we can take to help the emperor penguins' life so they will not decline in the future which can affect life on this earth

Kajian potensi pengembangan teknologi hidrogen sebagai sumber EBT melalui skema CDM dalam mendukung pencapaian NDC Indonesia

Background: In realizing the mitigation of global climate change, Indonesia is committed to participating in formulating policies for the use of environmentally friendly clean energy. One of the policy formulations produced is an effort to reduce emissions by implementing New and Renewable Energy (EBT). Findings: One of the potential uses of EBT that can be developed is hydrogen. Hydrogen technology is a potential fuel-producing technology because it can produce clean and sustainable energy sources without emissions. This article aims to review the prospects and challenges of the potential use of hydrogen-producing technology in Indonesia. Methods: To achieve this goal, the systematic literature review method is used in examining primary and secondary data sources from previous studies. The results of the literature study were then analyzed qualitatively (descriptively). Conclusion: The results of the study show that as a potential fuel, hydrogen is the most abundant element in the earth and can be produced based on the energy source used. In addition to its clean combustion features, the appeal of hydrogen as an environmentally friendly EBT comes from its greater level of effectiveness than gasoline. Based on the results of the comparative analysis, the opportunity for hydrogen production using geothermal energy in Indonesia is considered high because geothermal resources are widespread in several regions of Indonesia. The results of the study also revealed that the cost for small-scale geothermal utilization is 1.08 USD/kgH2 using a power plant. However, of all the resources considered in this article, Steam Methane Reforming (SMR) and coal gasification are the cheapest techniques related to operational technical factors and costs of 1.2 - 2.2 USD / kg.H2. With the CDM mechanism, Indonesia can use hydrogen EBT to achieve national emission reduction targets. This article ends with a form of proposal that can help implement CDM in Indonesia towards achieving national emission reduction targets or Nationally Determined Contribution (NDC)

Identification of urban green space availability and utilization in Semarang City

Background: Urban green space land a has been used differently because of Semarang City's rapid development in several sectors, including industry, transportation, and economics. Gajahmungkur Subdistrict determined that the minimum urban green space requirement of 30% had been reached. Methods: The method used in this research is quantitative method with remote sensing. Quantitative methods are used as systematic, rational, measurable, objective, and concrete methods. Findings: However, the identification results may not represent the total amount of urban green space in the village. Conclusion: Therefore, using remote sensing satellite image interpretation of Sampangan Village, the results of urban green space identification amounted to 22.97 ha or 22.6% of the 77.4% non-urban green space area with most of the land being urban green space of riparian type connected to Sampangan Park as a form of utilizing riparian urban green space which is frequently used by visitors to traders. In addition, Kelurahan Sampangan has urban green space utilization in the form of river borders, Sampangan Park, Sampangan Mitra Field, UNNES Labschool Elementary School sports field, Wotgaleh Cemetery, and parking lots. Sampangan Village only has 22.6% of the required minimum of 30% of urban green space, so it still falls short of the standard. Thus, efforts are needed to increase the provision of urban green space in Sampangan Village to become a residential area that is suitable for people to live in from an environmental aspect
