In daily life, waste is something that is always there. Finding out about the current waste management system in Medan Krio, Sunggal subdistrict, and Deli Serdang district is the goal of this study. Qualitative research using a descriptive observational design is the methodology employed. The study employed various research techniques, including field surveys, participant-led focus groups, open interviews, and literature reviews. Representatives from the Environmental Agency, village heads, village representative bodies, youth organizations, and village organizations were among the participants in this study. The study's findings indicate that the village's waste management is still inadequate. This is because there isn't enough land to erect temporary shelters, the infrastructure and facilities are still subpar, and there is still a low level of public awareness of the significance of proper waste management. A budget for the purchase of land that will be used for temporary housing should be included, along with recommendations for routine village clean-up schedules and socialization about proper and ethical waste management.

One non-organic waste that is used extensively in daily life is plastic, particularly for food packaging vendors and as a raw material for toy manufacturers. Waste will result from the vast amount of plastic that residents of Medan Krio use and discard after consumption. The goal of the research program's implementation is to enable locals to recycle waste materials to create valuable products. The village of Medan Krio Village has a high population density, which has led to the development of waste management issues. The village has traditionally disposed of waste by burning it and throwing it beside the street, which is why there is a garbage stench. which has a strong odor as a result of careless trash dumping. In light of this issue, Ecobricks may offer a way to lessen plastic waste and turn it into products with a positive economic impact. Method: PAR (Participatory Action Research), which is study that identifies issues and then offers potential solutions. Findings: The Ecobrick technique is being used in Medan Krio Village to make use of plastic waste. A recycling technique known as "ecobricks" uses plastic bottles that have been packed full of non-organic materials until they are extremely hard and dense.

The high consumption of cooking oil in daily life and food preparation both at the household level and in the food industry has resulted in an increasing amount of used cooking oil waste being produced. When the public is educated about the dangers of used cooking oil, there will be an increase in knowledge and awareness not to use used cooking oil again. However, this actually results in negative behavior in the community in managing used cooking oil waste which actually has a bad impact on the environment. This behavior includes used cooking waste from households that is thrown into the trash or thrown directly into the gutter. This can pollute the environment and if it is thrown into the dishwashing sink it will also clog the pipes. This behavior can be minimized by training in managing used cooking oil waste into decorative candles with economic value. This activity is carried out using counseling, demonstration and training methods. The result of this service activity is an increase in community skills in managing used cooking oil waste. So it is hoped that education and training like this can continue to be carried out

E-waste has become a critical global issue due to the rapid growth of electronic product consumption and the environmental risks associated with improper disposal. Traditional disposal methods, such as landfilling and incineration, are no longer sustainable as they lead to environmental degradation, health hazards, and loss of valuable resources. In contrast, remanufacturing, a key component of the circular economy, offers a more sustainable solution. This study explores the effectiveness of remanufacturing as a strategy for e-waste management, focusing on its ability to reduce waste generation and improve material efficiency in the electronics industry. The research utilizes a case study approach, examining industrial-scale remanufacturing processes, including material input-output analysis to track resource flows and waste streams. The findings reveal a significant reduction in e-waste generation, with up to a 50% decrease in waste volume, and substantial improvements in material recovery, particularly in metals like gold and copper. Additionally, the study highlights the economic and environmental benefits of remanufacturing, such as cost savings and resource conservation. However, the study also identifies barriers to the widespread adoption of remanufacturing, including technological, financial, and regulatory challenges. The results underscore the potential of a circular-economy-based remanufacturing model as a sustainable solution for the electronics industry. The study calls for further research into improving remanufacturing technologies, enhancing policy frameworks, and expanding circular economy practices across various industries.

There are 514 urban areas in the archipelagic nation of Indonesia (Ministry of Home Affairs, 2016). There are many cities in Indonesia that are able to provide a sense of comfort and security for their residents, this of course has an impact on population growth. However, the amount of waste that can be generated and stored is limited by the carrying capacity of the urban environment. Using the idea of ​​a "green city" which consists of nine elements of road infrastructure, traffic, green open space, clean water, noise, energy, housing, clean air and buildings is one way to overcome the above problems. All these qualities need to be utilized immediately with a comprehensive systems approach and in accordance with economic, social and environmental principles in sustainable development. Blue economy approaches can be used to eliminate waste. The “blue economy” is a term that is becoming increasingly popular in today's seas and oceans. The aim of this concept is to combine sea base development opportunities with environmental management and protection. Four conceptual interpretations of the blue economy were determined through research into the dominant discourse in international economic policy documents. How the blue economy works is also examined through an “in practice” analysis of the blue economy and related actors. Next, the scope and focus of the blue economy is explored specifically on the maritime industry, which is included or excluded in various conceptualizations. This analysis reveals areas of agreement and conflict. The consensus range reflects the growing trend towards the commercialization and valuation of nature, delineating and defining maritime boundaries and enhancing the security of the world's oceans. There are several areas of conflict, particularly disputes over the legitimacy of individuals as part of the “blue economy”, highly carbon-intensive industries such as oil and gas and the growing deep sea mining industry. Oceans are becoming increasingly important in terms of potential international trade opportunities through intermediaries and buyers. the behavior of the model supporting such a relationship in the ocean is acceptable from a regular and economic point of view. The relationship between land and sea is increasing in the role and importance of the "blue economy" as the term emerges in the background. . A literature review was conducted to analyze the correct definition of the blue economy. This definition is analyzed based on the minimum requirements that are important for the blue economy. This article also tries to compile various types of activities related to marine services. This is done to determine what can be considered priority areas for blue economic growth. The blue economy concept is based on national economic development. This is comprehensively useful for achieving overall national development. Environmental accounting is stated as a process of reducing negative values ​​and creating positive values ​​in environmental accountability.

STBM is a comprehensive approach that not only includes sanitation infrastructure development, but also emphasizes changes in community behavior and sustainable waste management. Thus, in the implementation of STBM, the 3R Waste Disposal Site (TPS) is a key component in sustainable waste management. TPS 3R refers to waste management with the 3R principles, namely Reduce, Reuse, and Recycle. However, in this case Menur Pumpungan Village still does not have a 3R-based waste processing facility. So it is necessary to plan the optimal design of TPS 3R to be applied in the future and be able to make a significant contribution in efforts to realize Community-Based Total Sanitation. To calculate the number of TPS 3R services as the basis for design, data on the population in 2023 and the waste generation rate of 2.6 liters/person/day were used. Based on the calculations made, in an effort to support the implementation of the Community-Based Total Sanitation program. The construction of TPS 3R, which is planned to be able to serve the domestic waste processing of the entire Menur Pumpungan urban village community, is expected to reduce the amount of waste entering the landfill. The total land required for operational facilities is 511.85 m2 with a TPS 3R design consisting of a 440.85 m2 waste processing area and 96 m2 of other supporting facilities..

Emulsifier is one of the oleochemical products with high economic value. An alternative material that can be used as an emulsifier is pliek oil. The catalyst that can be used in the emulsifier production process is NaOH. The addition of this catalyst can enhance the glycerol's ability in oil to break down fatty acids, accelerate reactions, and suppress the reformation of diglycerides, which are then converted into monoglycerides through the more active glycerol and NaOH. This research aims to analyze the functional groups of the emulsifier substance, the influence of time and the amount of NaOH catalyst, and the characteristics of the emulsifier substance obtained from pliek oil with NaOH catalyst using the glycerolysis process. The research results show that in the FT-IR test, there is a peak at the wavenumber of 3741 cm-1, indicating the presence of the O-H group. The absorption peak at the wavenumber of 1506 cm-1 is characterized as the stretching vibration of C-C. At the wavenumber of 1273 cm-1, there is the presence of the C-N group. The influence of time and NaOH catalyst on the emulsifier substance, with the highest values based on the yield test, is obtained at a reaction time of 1 hour with a 4% catalyst, yielding 93.73%; the saponification value, with the highest value obtained at a reaction time of 2.5 hours with a 4% catalyst, is 161.41; the best acid value is obtained at a reaction time of 2.5 hours with an 8% catalyst, amounting to 0.35.
