Learning Effect Based on Socio-Scientific Issue on Students Learning Outcomes in Environmental Pollution Materials in Senior High School 1 of Meureubo, West Aceh, Indonesia (Published)
Biology is part of the natural sciences that discusses all aspects of life, both related to living things and the natural environment that supports the life of these living things. The biotic and abiotic components and their maintenance are important focus on biology learning. Students need a good understanding of their surroundings, maintaining, and controlling existing resources so they can take part as environmental preservation. Learning about the environment should have been designed and implemented with a learning model that is considered very appropriate to arouse interest as well as concern for students using learning models that synergize with efforts to preserve nature and the environment. Wrong on the environment is a learning model based on Socio-Scientific Issues. This study aims to determine the effect of Socio-Scientific Issues learning in environmental pollution learning in class X of SMAN 1 Meureubo West Aceh Regency. The approach used is a quantitative approach with the research design used is “Nonequivalent Control Group Design”. The research data is in the form of student learning outcomes data on environmental pollution material on the application of Socio scientific-based learning issues on learning environmental pollution material. Learning outcomes data are analyzed using linear regression analysis followed by T test and F test. The results showed that there were significant differences in student learning outcomes and students response to the application of a socio scientific based learning model between before and after the application of the model. Through improved learning outcomes and students response to environmental pollution material, it is hoped that this can be a trigger for the movement to protect the environment from an early age.
Owing to the on-going exhaustion of the natural environment and its consequences on the society, the present environmental state of Bangladesh, a populated country with inadequate resources, has become enormously alarming. The human health, ecosystems and economic growth are threatened by severe environmental pollutions and encroachments. Bangladesh is facing several natural catastrophes such as floods, cyclones, and tidal-bores every year because of the environmental externalities which cause severe socio-economic and ecological damage. Thus, this study aims to highlight various ecological difficulties that Bangladesh is currently facing and that pose obstacles to implementing environmental CSR for sustainable development. The review of the literature reveals that several environmental pollutions, climate change and the loss of biodiversity are continuously degrading the natural environment of Bangladesh and its resources. Consequently, these detrimental impacts are threatening the socio-economic growth of Bangladesh and its environment. Hence corporate social responsibility (particularly environmental) can play a significant role to control the current environmental degradation of Bangladesh. The government should, at the same time, undertake several initiatives to protect environmental degradation, foster the environmental CSR activities within all the business sectors and increase environmental awareness which is mandatory to attain sustainable development.
Can good environmental policy and planning reduce the negative external consequence that industrial activity can cause, to the environment? To what extent is the current level of industrial activity causing environmental degradation and affecting regional ecological environment across? Industrialization in many developing and developed countries is often associated with negative environmental consequences such as noise pollution, air pollution, water bed pollution and land degradation. Industrial waste and waste attributable to consumables from industrial final products also accounts for more than 65 Percent of all known waste worldwide IEA Report 2013. This study investigates the effect of regional Industrial Activity on environmental pollution using data from six regions worldwide. It was found that industrial activity were a principal causative agent of environment pollution and it is suggested that strategic planning and good policies to mitigate environmental pollution should be strengthened.
Effectiveness of Environmental Pollution Control Measures Implemented in Stone Crushing Sites Located at Kaduwela Municipality, Sri Lanka (Published)
Stone Crushing industry plays a major role in supplying construction materials in Sri Lanka. Although it gives a better financial and social development to the nation, the caused environmental pollution significantly influences the future sustainability of the industry. Therefore, this study was aimed to evaluate the effectiveness of pollution control measures that are already implemented in Welehandiya area in Kaduwela Divisional Secretariat in Colombo District by the Central Environmental Authority (CEA). Since the noise pollution and the dust emission were identified as the major impact categories, the equivalent continuous sound pressure level and concentration of Suspended Particulate Matter (SPM) in ambient air were measured in the study area. As the measurements were done after the successful implementation of recommended pollution control measures, results revealed a substantial reduction of noise level and very slight reduction of SPM levels recorded. Finally, the recommended noise pollution control measures can be introduced to similar industries while dust emission control measures need to be improved innovatively. Further intensive studies are required to analyse the effectiveness and generalize the results in future.
