Abstract

Limbah cair dari pabrik tahu mengandung senyawa organik tinggi, seperti protein dan asam amino, yang menurunkan kualitas air sungai melalui peningkatan Total Dissolved Solids (TDS), penurunan pH, dan penurunan oksigen terlarut. Dampak ini merusak ekosistem akuatik dan mengancam kesehatan masyarakat dengan risiko seperti penyakit kulit dan gangguan pencernaan. Metode penelitian melibatkan survei dan wawancara dengan warga serta pekerja pabrik, disertai observasi langsung di lokasi. Analis menunjukkan bahwa tingkat pengetahuan pengelolaan limbah oleh produsen tahu rendah, dan kurangnya fasilitas pengolahan air limbah (IPAL) mengakibatkan pencemaran yang parah. Limbah tersebut juga mencemari udara dan tanah, meningkatkan risiko gangguan pernapasan dan menurunkan kesuburan tanah. Penelitian ini merekomendasikan pengelolaan limbah yang lebih baik dengan pembangunan IPAL yang memadai, penerapan teknologi fitoremediasi, serta peningkatan regulasi dan kesadaran industri untuk melestarikan lingkungan. Diharapkan langkah-langkah ini dapat mengurangi dampak negatif limbah pabrik tahu, meningkatkan kesejahteraan masyarakat, dan menjaga kelestarian ekosistem sungai.

Abstract

Currently, development can be seen everywhere, there is a lot of land clearing by infrastructure development which can cause damage to the environment itself which can cause various environmental problems such as floods, landslides, extinction of endangered animals, lack of clean water, increasing air pollution. This research aims to determine the relationship between humans and natural resources and the environment as well as the role of humans in managing natural resources and the environment based on a philosophical perspective. This research is a qualitative descriptive research with data collection using literature study techniques using secondary data. The results and discussion show that the relationship between humans and natural resources and the environment reflects a complex interaction between needs, activities, influences, responsibilities and human awareness of the environment in which they live. So there needs to be a human role in it based on existing ethics and the two environmental ethics have differences, namely the difference in approach between ecopocentric and anthropocentric results in different priorities in managing natural resources and the environment. The ecopocentric approach emphasizes environmental preservation as the main goal, while the anthropocentric approach places more emphasis on the use of natural resources to improve human welfare.

Abstract

This paper explores the view of the responsibility of the Khalifah on earth in maintaining nature optimally. The sacralization of the universe triggers moral and religious responsibilities among Muslims to care for environmental sustainability. The environment is the place where all the activities of living things in the world take place. Environmental protection is a human job. The environment has a great influence on human life. The environment can change its function due to various factors, one of which is due to the global era. Ecological awareness is very important for people to cope with environmental changes. In addition, the deterioration of natural conditions continues, which is concerning. Ecological awareness can start with the application of environmental ethics. Environmental ethics can be addressed by changing the way we think and live as a whole rather than as individuals. There is a correlation between environmental ethics and the word of Allah SWT in Surah al-Araf verse 56, which prohibits humans from destroying the earth after Allah SWT restores it. The purpose of this study is to explain what is meant by environmental ethics and related issues. And knowing that the correlation between environmental ethics and the synthesis of the Qur'an from the 56 verses of Surah al-Araf is how the people live as the Qur'an.

Abstract

This research focuses on the balance between land use and land preservation, with a case study of land degradation in Sekaroh Village, Jrowaru District, East Lombok. Land degradation in this area is triggered by changes in land use, unsustainable agricultural practices, and a lack of effective conservation policies. This study employs a qualitative approach using a literature review to explore the factors influencing land degradation, the resulting socio-economic impacts, and community empowerment efforts in land rehabilitation. The findings reveal that land degradation not only threatens environmental sustainability but also reduces the welfare of local communities reliant on agriculture. Through community empowerment, as implemented in the critical forest and land rehabilitation programs in Sekaroh Village, conservation efforts can be carried out by actively involving communities in ecosystem preservation. This participatory approach is deemed effective in achieving a balance between land use for economic purposes and environmental preservation efforts. Recommendations include the adoption of sustainable agricultural practices such as agroforestry, soil conservation, and the provision of education and training to local communities. Policies supporting land conservation and economic incentives to promote environmental preservation are also considered important. Thus, a sustainable balance between land use and preservation can be achieved.

Abstract

This study discusses the management of coastal resources in the Province of West Nusa Tenggara (NTB) with a focus on current conditions, integrated management strategies, and policy recommendations. The NTB Provincial Government has issued NTB Governor Regulation Number 100 of 2023 concerning Whale Shark Management in the Saleh Bay Waters to regulate management and tourism activities in the area. However, challenges such as environmental degradation, land use conflicts, and climate change remain major obstacles. This research employs a literature review method with a normative approach and qualitative data analysis. The results indicate that effective coastal resource management requires the integration of local knowledge, community-based management practices, and sustainable management policies. Active community participation and collaboration between the government, communities, and other stakeholders are crucial to achieving harmony between economic utilization and environmental conservation. One of the coastal areas that has become a tourist destination and a coastal management program is in Labuhan Jambu Village, Sumbawa, which focuses on whale shark ecotourism. Awareness of human responsibility towards nature and the integration of science, technology, and local values are also necessary for the sustainable management of coastal resources in NTB.

Abstract

Waste management with the old paradigm (collection, transportation, disposal) causes waste to be concentrated in landfills in large quantities (Tchobanoglous et al., 1993). Waste that ends up in landfills will undergo a decomposition process and cause emissions of one of the GHGs, namely methane gas (CH4). This gas causes an effect 20-30 times greater than carbon dioxide gas (CO2) (Damanhuri, E., & Padmi, T., 2015. Effective waste management in urban areas poses a major challenge in reducing greenhouse gas (GHG) emissions and ensuring environmental sustainability. This research analyzes the optimization of waste management and recycling as a strategy to lower GHG emissions in several major cities in Indonesia. A qualitative approach was employed, utilizing surveys and interviews with stakeholders, including government, waste managers, and community members. The findings indicate that an integrated management system, accompanied by educational programs and incentives for community participation, can enhance recycling rates and reduce waste volume. The reduction in GHG emissions positively correlates with decreased poorly managed waste and increased use of recycled materials. This study emphasizes the importance of collaboration among government, community, and private sectors in creating sustainable management systems, while recommending policies to raise awareness and improve urban waste management infrastructure, ultimately supporting the conservation of natural resources.

Abstract

The waste problem in Indonesia has become a serious problem. As much as 64.88% of the tens of millions of tons of waste per year is organic waste. Although classified as organic waste, this remains a major concern due to the various negative impacts caused by it. The purpose of this study was to explore the latest information regarding the effectiveness of maggots in overcoming the problem of organic waste. The research method used in writing this article is descriptive analysis with a literature study method. The results of the study indicate that maggots are able to decompose organic waste by actively eating it for 2-3 weeks for the growth process. By eating organic waste, these black soldier fly larvae are able to grow and develop well. Therefore, organic waste can be decomposed and reduced by making it into maggot feed. In addition, the maggots produced can also be used as feed for chickens, fish, or other animals. The remaining organic waste decomposition by maggots can also be used as organic fertilizer that fertilizes the soil. Thus, it can be concluded that black soldier fly larvae (maggots) have proven effective in overcoming the problem of organic waste.

Abstract

The background of the problem underlying this research is the students' low understanding of basic scientific concepts such as the introduction of nature, animals, plants and the surrounding environment. This can be seen from the results of initial observations that show a gap in the ability to recognize, read, and write related to the world of science. This type of research is descriptive research with a qualitative approach. The data collection techniques used include observation, interviews, and documentation. The main data sources came from students, teachers, and observations of learning activities carried out at Nurul Illmi Kindergarten. Data analysis techniques were carried out inductively, by identifying patterns in the data obtained to draw conclusions related to the impact of the application of science literacy. The results showed a significant increase in students' scientific thinking skills after the science literacy program was implemented. Out of 30 students, 22 students showed good progress, 5 students were in the moderate category, and 3 students were still in the deficient category. This indicates that the program is effective in improving children's understanding and scientific thinking skills. As a follow-up, this study serves as a reference for researchers and teachers to look more carefully at science literacy programs as a fundamental need for children in learning.
