Green Belt Policy and Community Participation to Control Urban Heat and Air Pollution in Semarang City
type: item
description: This study aims to evaluate the effectiveness of the Green Belt Policy in controlling urban heat and air pollution in Semarang City, with a particular focus on the role of community participation in its implementation. A mixed-method approach was applied, combining legal analysis through statute and conceptual approaches with field research. Primary data were obtained from the Public Works Department (Dinas Pekerjaan Umum) of Semarang City, providing information on the extent, maintenance, and challenges of green belt areas, and from the Environmental Agency (Dinas Lingkungan Hidup), which supplied air quality index records and urban temperature data. Additional data were gathered through literature review, direct observation, and interviews with local communities. The results indicate that although green belts contribute to reducing local air temperatures and improving air quality, their potential is not fully optimized due to limited maintenance budgets, inadequate human resources, and low public involvement. Community participation remains minimal, largely due to a lack of awareness and incentives. Strengthening regulatory enforcement, integrating community-based management, and utilizing environmental monitoring technology are recommended to enhance the policy’s impact. These findings can serve as a reference for local governments in other urban areas to adopt similar strategies for sustainable environmental management

Integrating Inquiry-Based Learning within the 5E-Framework: Implications for Preservice Science Teacher Education
type: item
description: This study examines the effect of integrating inquiry-based learning within the 5E-Framework on enhancing conceptual understanding and critical thinking skills in the topic of density among pre-service teachers at Bagabaga College of Education, with attention to gender differences. Using a one-group pretest–posttest design, data were collected from Level 200 pre-service teachers (N = 52) and analyzed using SPSS. Results showed no statistically significant difference in normalized gain scores between males (mean NG = -0.045) and females (mean NG = -0.044); t(50) = 0.965, p > .05, indicating the model improved conceptual understanding similarly across genders. However, significant gender differences were found in critical thinking dimensions: analysis (p = .000, η² = .221) and logic (p = .005, η² = .129), while no significant difference was observed in the evaluation dimension (p = .444, η² = .010). These findings suggest that while integrating inquiry-based learning within the 5E-Framework is effective in supporting general learning gains in science concepts such as density, differences in specific cognitive skills remain. The study recommends incorporating targeted interventions to ensure more equitable development of critical thinking across genders in science education

Beyond Awareness: The Role of Environmental Literacy in Sustainable Fashion Behaviour Among Forestry Students
type: item
description: The fashion industry is rapidly expanding while exerting significant pressure on the environment through carbon emissions, textile waste, water pollution, and deforestation. This study investigates how environmental knowledge influences sustainable fashion behavior among forestry students at Tadulako University. A quantitative survey was conducted with 50 purposively selected students who had received basic environmental education. The data were analyzed using descriptive statistics, Pearson correlation, and multiple regression. Results show that overall environmental knowledge is positively related to sustainable fashion attitudes and behaviors, with correlation strengths ranging from weak to moderate. Multiple regression produced an R² of 0.495, indicating that the independent variables collectively explain nearly half of the variation in sustainable fashion behavior. Among the seven knowledge indicators, the ability to seek and read information on sustainable fashion (X6) emerged as the only significant predictor, strongly linked to practices such as reading garment care labels and upcycling. These findings highlight the critical role of practical, applicable knowledge in fostering sustainable fashion consumption

Effectiveness of Mendong (Fimbristylis globulosa) as A Phytoremediation Agent for Total Ammonia and Total Nitrogen Leachate
type: item
description: Landfills are one of the causes of environmental pollution resulting from the disposal of human activity waste without further treatment (Yusri et al., 2020). In 2023, the total waste generation reached 1,270.00 tons per day, with 900 tons of waste being transported to the landfill each day (Harjanti, 2020). This waste accumulation produces leachate—a thick, dark-colored liquid that carries pollutants and materials from the waste—which has the potential to contaminate the surrounding environment, including the Kreo River. Therefore, phytoremediation using Mendong plants is proposed to reduce the pollutants in the leachate. This research employed an experimental method with a Completely Randomized Design (CRD), using Mendong plants (Fimbristylis globulosa) and three biomass variations: P0 (0 g), P1 (1000 g), and P2 (2000 g). Each treatment involved 10 liters of leachate and was replicated three times. The phytoremediation process proved effective in reducing total ammonia levels in the leachate, with a reduction of up to 63%, and the highest total nitrogen reduction reached 53%. This phytoremediation approach can assist in reducing excess total ammonia in water bodies by absorbing organic pollutants through plant roots, as Mendong exhibits hyperaccumulator and hypertolerant properties. It is concluded that Mendong plants are effective in lowering total ammonia and total nitrogen levels in landfill leachate.

Biodegradation of Polystyrene Waste using Mealworm (Tenebrio molitor) Larvae as a Sustainable Waste Management Approach
type: item
description: Styrofoam is widely used as packaging for food, drinks and electronic goods. Usually stirofoam is only used once and thrown away. Styrofoam causes environmental problems, so efforts are needed to degrade it. Using larvae Tenebrio molitor is expected to be an innovative and environmentally friendly solution. The larval stage is used because larvae require large amounts of food for their growth. The larvae's food consists of organic waste such as fruit, vegetables, leaves, rice and others. In fact, stirofoam is considered organic waste because it is made from petroleum which contains hydrocarbons. T. molitor were chosen because they are not consumed by humans. This research aims to analyze the ability of T. molitor to be biodegradation agents for stirofoam. The research stages include cultivating T. molitor for 30 days and analysis which includes viability analysis and larval content using FTIR. The research method used is an experimental method with quantitative data collection. The results of the study showed that even though there was chewing activity, there was no stirofoam content in the bodies of T. molitor.

The findings indicate that the primary actors in mangrove management in Mundu are the Community-Based Coastal Resource Management group (Pokmaswas), which has a degree centrality of 1.2222; the Village Government, with a value of 1.3333; and the Department of Marine Affairs and Fisheries, which has a value of 0.6666. These results suggest that both Pokmaswas and Village Governments play central roles in mangrove management, with the Department of Marine Affairs and Fisheries following closely behind. This highlights the critical contribution of community groups to the success of mangrove conservation efforts in the region. However, UCINET analysis also reveals that interactions among stakeholders are limited, indicating a gap in collaboration. This lack of interaction may lead to suboptimal management and hinder the development of the mangrove ecosystem in Mundu.

type: item
description: Waste is one of the most common environmental problems, including organic and inorganic waste that is often found around settlements. The Heuleut Landfill in Majalengka Regency, West Java, has a problem of waste accumulation that exceeds its capacity, causing negative impacts on the environment and the health of the local community. The volume of waste is estimated to be more than 100 tonnes per day, with an average of about 0.7 kg of waste per person per day. This research used a descriptive qualitative approach, collecting primary data through field observations and interviews, and secondary data through document analysis. The research findings show the significant impacts of the Heuleut landfill management, including soil, water and air pollution, which affect health and agricultural yields. The results of the analysis were used as a supplement to the ecology course. The students' positive response to waste management reflects an increased level of environmental awareness. Waste management through the 3Rs (Reduse, Reuse, Recycle) method, such as the production of briquettes, pulp and compost, as an alternative to environmentally friendly waste management was presented to the students using interactive Flash Player applications to enhance their understanding. In conclusion, better waste management is needed so that Heuleut Landfill does not only function as a final disposal site, but also plays an active role in waste management by applying the principles of the 3R's. This is an important step in maintaining environmental sustainability and the welfare of the local community.

Effect of Learning Motivation on Science Literacy of 11th grade studentsof MAN on Climate Change material
type: item
description: The concept of motivation to learn encompasses a wide array of components. The attributes mentioned above collectively have an influence on the cognitive processes, emotional states, interpersonal relationships, and behavioral patterns of students in various educational and non-educational settings. While Fives, et al. (2014) classify scientific literacy into 5 components, namely: the role of science, scientific thinking and activities, science and society, mathematics in science, and science motivation and beliefs. In addition, the Program for International Student Assessment (PISA) framework from the OECD (2019a) defines scientific literacy as the ability to engage with science-related problems and with the idea of science as a reflective citizen. This research design uses correlation research to measure the research results, learning motivation as the independent variable and scientific literacy as the dependent variable. The approach used in the research is the survey method. From the overall results and discussion of the research above, it can be concluded that: Based on the R square value of 0.077 in the table above, learning motivation affects science literacy by 46.2%, for the remaining 53.8% ecoliteracy is influenced by other factors. Based on the results of the table above, it is known that the sig. value is 0.102> 0.05, so it can be concluded that learning motivation has no effect on students' scientific literacy.

A Comprehensive Analysis of Ambient Air Quality at Pitalganj Depot of Dhaka Metro Rail Line 1 Project
type: item
description: The Dhaka Metro Rail Line 1, also known as DMRT Line 1, is the first subterranean metro rail project in Bangladesh, and is currently undergoing depot construction work under contract package-1 (CP 01). The construction of depot work is mainly susceptible to ambient air quality due to the land development and soil improvement activities. The long-term construction period can significantly impact the surrounding air quality of the project area and so it is crucial to identify air pollution concerns and analyze the impact of air quality on the environment. This study evaluated ambient air quality in four distinct zones of the depot area from June 2023 to September 2024. There were several pollutants measured in the ambient air including Particulate Matters (PM10 and PM2.5), Ozone (O3), Lead (Pb), Sulfur Dioxide (SO2), Nitrogen Dioxide (NO2), Carbon Monoxide (CO). The air quality monitoring machine Oceanus AQM-09 and Haz-Scanner (HIM, 6000) were used for 8 hours on the site. The power-law equation of Schroeder and Jugloff, 2012 was applied to provide 24-hour and 8-hour averages for the air quality parameters. It is observed that in pre-monsoon period of 2024, there is quite high intensity of particulate matter (PM2.5) present in the air, whereas other air pollutants values were found in all four zones are moderate in the air samples as prescribed by Air Pollution Control Rules, 2022.

type: item
description: Gili Iyang Island is one of the islands in Sumenep district, Madura Indonesia, which is known as the island with best oxygen after research by Lembaga Penerbangan dan Antariksa Nasional (LAPAN) with an average oxygen level of 20.9%. In 2022, there will be research by the Faculty of Advanced and Multidisciplinary Technology, Air Langga University which states that the oxygen level on Gili Iyang Island has an oxygen level of 20.3%. As a tourist village in Sumenep district, its existence is an attraction for tourists for oxygen tourism. How can the community and local government protect this area so that it remains sustainable? This research aims to see the extent to which the conservation of Gili Iyang Island is carried out using an ecophilosophy perspective. This research was conducted using a qualitative approach through data triangulation including interviews, observation, and documentation and supported by literature studies. The research results show that the people of Gili Iyang is quite good at protecting the nature of this island. There have never been any complaints about illegal felling of trees or pollution activities that have caused oxygen levels to drop significantly. Many trees grow abundantly on this island, while people's use of motorized vehicles is still relatively normal, and the cleanliness of the island at many points is also well maintained. Even so, wise behavior towards nature as taught by ecophilosophy must continue to be socialized and intensive education given to local communities. The eco-philosophy pattern implemented by the Gili Iyang community must be maintained and improved through sustainable conservation on the island they live on.

Mapping the Dynamics of Mangrove Density in Alas Purwo National Park using the ARVI Index
type: item
description: This study aims to compare the sensor/Top-of-Atmospheric (TOA) reflectance correction method and surface reflectance correction in the ARVI (Atmospherically Resistant Vegetation Index) vegetation index transformation application. The resulting comparison of the two has a correlation that is not much different, sensor reflectance correction (R = 0.9723) and surface reflectance correction (R = 0.9781) are both able to represent mangrove forest canopy density well. The model accuracy resulting from the surface reflectance correction RMSE 1.408 and MAPE 0.48%, is higher than that of the sensor correction (TOA) which has an RMSE value of 2.184 and MAPE 1.34%. For advanced remote sensing analysis, it is better to perform radiometric correction of surface reflectance because the reflectance value used for analysis is the true reflectance value. The condition of mangroves in Grajagan Bay in Alas Purwo National Park is very well preserved, this is shown by the mangrove canopy density >50% increased by 49.11 Ha in a period of 7 years from 2016 to 2023.

Effectiveness of Water Bamboo as Phytoremediation Agent BOD and COD Leachate
type: item
description: Leachate is a liquid with an unpleasant odor and dark color that generally contains high organic and inorganic matter. High levels of organic and inorganic matter in leachate will potentially cause environmental pollution if not treated properly. One of the efforts that can be made to overcome these problems is with phytoremediation techniques. This study aims to determine the effectiveness of water bamboo (Equisetum hymale) as a phytoremediation agent of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) leachate of Jatibarang landfill. This study used experimental research with a one-factorial Complete Randomized Design (RAL) design with three treatments (P0 without water bamboo, P1 750 gr water bamboo, and P2 1000 gr water bamboo). Based on the results of research shows that water bamboo plants can reduce BOD and COD levels. The decrease in leachate BOD levels was caused by the phytoremediation process by water bamboo during the study, where the organic matter content in leachate would be degraded by microorganisms. Meanwhile, COD levels decreased due to the chemical oxidation reaction process and phytoremediation process that runs side by side. The effectiveness of reducing BOD levels most optimally occurred in treatment P2 on day 7 of treatment, which was 28.42%; while the percentage of effectiveness of reducing COD levels most optimally occurred in treatment P2 on day 7 of treatment, which was 39.14%
