Abstract

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.

Abstract

The Gunung Kuda mining area in the Cipanas Village area, Dukupuntang District, Kuningan Regency has the potential for natural resources as a type of C excavation mine with a limestone soil texture where the results are partly used as raw materials for cement, natural stone and ceramics. The aim of this research is to examine the impact of Gunung Kuda mining activities on environmental quality as a source of SDGs-based science learning. The research method used is descriptive qualitative. Data collection techniques were carried out using open interviews, field observations and literature reviews. The results obtained show that Mount Kuda mining activities have positive and negative impacts. The positive impact felt by the surrounding community is as a center of livelihood to stabilize the economy. However, there are also negative impacts in the form of decreasing the quality of the surrounding environment, such as the river in the Gunung Kuda mining area which is classified as moderately polluted, namely with a value of Plj 10.39; air pollution in the form of dust resulting from the breakdown of rocks; as well as reduced vegetation in mining areas. Efforts made by the management and surrounding communities to balance the environment in the mining area are by replanting trees that have been reduced due to the mining process with trees that are considered to have benefits such as mango trees, durian trees and sengon trees. The results of the analysis of the impact of Mount Kuda mining on environmental quality are suitable as a study in SDGs-based contextual science learning resources.

Abstract

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.

Abstract

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.

Abstract

The mangrove area in Tritih Cilacap, Central Java is decreasing due to illegal logging. This affects the distribution pattern of gastropods. This study aims to determine the distribution pattern of gastropods and provide information related to physical chemical factors that play a role in gastropod distribution patterns. This study was conducted at five sampling points. Five sampling points from the sea to the land. The sampling method used for gastropods was collection from 1x1 m plots. Gastropods in the plot were collected by hand on the top of the sediment and in the sediment were taken 10 cm deep using a corer with 3 repetitions for each station. Environmental parameters measured were: temperature, salinity, organic matter content, pH, and substrate type. The distribution of gastropods in Tritih Cilacap mangrove forest has a clustering and random pattern. There were 11 species of gastropods found from 7 families. Gastropod species that have clustered distribution patterns are: Ceritidhea alata, Telescopium telescopium, Neritina violacea, Neritina zigzag, Chicoreus capucinus, and Assimenia brevicula. Gastropod species that have random distribution patterns are: Ceritidhea quadrata, Neritina lineata, Cassidulla aurisfelis, Cassidulla nucleus, and Littoraria carinifera. The results of BIOENV analysis showed that the most influential environmental factors on gastropod density were water temperature, salinity, organic matter content and sand substrate.

Abstract

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.
