Abstract

The growth of the population and the development of the city are interrelated. Each increase in the population has an impact on the growth of the city, and vice versa. With the increasing population, the demand for settlement land also increases. Consequently, the availability of land becomes more limited and diminishes every year. Medan city is an example of a city experiencing rapid regional growth and development due to fast population growth, leading to an increase in land requirements. The author examines the regional development of Medan city, urban spatial planning approaches, and environmental issues faced by the city's growth. The author employs a qualitative approach and utilizes qualitative descriptive techniques based on literature research. The research results indicate that the residential area of Medan city has increased by 235.94%, rising from 84.56 km2 (1989) to 199.50 km2. The city's development pattern in 1989 was leap frog development, while in 2002, it showed concentric development. From 2007 to 2018, the Medan Marelan district experienced significant development, amounting to 491.06 hectares.

Abstract

Waste management has currently become a significant problem faced by every segment of society, from individuals to institutions. It is almost certain that the amount of waste will increase each year due to Indonesia's large population. According to data from the Ministry of Environment, the general waste generated is approximately 2.5 liters per person per day or equivalent to a total of 625 million liters. The method used in writing this article is a qualitative approach through literature review or literature study. The literature used in this writing consists of scientific articles relevant to the discussion of imported waste. Since 2018, the Chinese government has successfully reduced the level of plastic waste imports due to policies restricting waste imports. This has led waste-exporting countries to seek new target markets, especially in Southeast Asia. The issue of waste imports in Indonesia persists despite existing bans, as there is still imported waste used as a source of livelihood for the community. Importing waste has environmental and environmental pollution crises and negative impacts on human health due to water and air pollution caused by imported waste management. Regulations regarding the ban on waste imports will be effective with the involvement of the community, starting with knowledge about waste, waste management, and its dangers. The role of the community in the recycling process is crucial to reduce the burden of waste collection, industrial and hazardous waste, mitigate environmental impacts, and increase income.

Abstract

Background: Indonesia, as the largest palm oil-producing country in the world, will also produce palm oil mill effluent (POME). POME production from palm oil processing is faced with many environmental problems from the release of emissions. The development of new renewable energy in Indonesia needs to be increased to reduce dependence on fossil energy and commit to reducing greenhouse gas emissions. The purpose of this study is to discuss the potential for new renewable energy from the utilization of POME biogas energy and how the environmental impacts are caused as well as the opportunities and challenges of developing EBT from POME.  Methods: This research analysis method is LCA, and descriptive. Findings: Total CO2 emission (eq) of biogas production from POME is -24.62 Kg CO2 (eq), eutrophication is -0.2188 Kg PO43- (eq) and acidification is 0.00552 Kg SO2 (eq). Biogas production from POME in Jambi Province is not optimal and has not been used optimally, the process efficiency is low, and the profitability is low. Conclusion: There is a need for a concept to utilize biogas energy that does not only focus on electrical energy but also as a renewable energy source such as bio-CNG which has wider use. Novelty/Originality of this article: The novelty of this research lies in the comprehensive analysis of the utilization of Palm Oil Mill Effluent (POME) as a renewable energy source that is not only limited to electrical energy but also includes the potential conversion of POME into bio-CNG as a more flexible and sustainable alternative.

Abstract

The aim of this research is to see how economic growth, poverty, and welfare levels in North Sumatra Province, Indonesia, relate to each other. This research investigates how these components interact in regional development using various theoretical frameworks. This research method involves the analysis of secondary data from North Sumatra Province, including data on economic growth, poverty levels, and indicators of people's welfare. Economic data will be evaluated using economic growth theory, and factors such as access to clean water, electricity, schools, health facilities, and infrastructure will be considered in the poverty and welfare analysis. It is hoped that the results of this research will provide in-depth insight into how economic growth impacts community welfare and poverty levels at the provincial level. It is hoped that this research will provide policy benefits for local governments as they create plans for sustainable economic development, improve community welfare, and overcome poverty.
