Strategy Design Dynamic System-Based Circular Supply Chain Management on Waste Management in Sleman Regency, Yogyakarta

/in /by

This study aims to design a dynamic system-based Circular Supply Chain Management (CSCM) strategy for waste management in Sleman Regency, Yogyakarta. The increase in population and economic activity has led to a significant increase in waste volume, necessitating a sustainable and efficient management model. The CSCM approach is used because it integrates circular economy principles through the 5R concept (Reduce, Reuse, Recycle, Recover, and Redesign) to create a closed-loop supply chain system for waste management. The research method uses a system dynamics approach. Modeling with qualitative and quantitative analysis stages through the creation of Causal Loop Diagrams (CLD) and Stock and Flow Diagrams (SFD). Research data were obtained from field observations, interviews with the Environmental Agency, and supporting literature. Simulation results show that the existing waste management model in Sleman has implemented some CSCM principles but is still semi-linear. Through the development of four simulation scenarios, Scenario 4, which integrates the Organic Processing Center (OPC), the Plastic Shredding 3RWPS (Reduce, Reuse, Recycle (3R) Waste Processing Site), and the Compost IWPS (Integrated Waste Processing Site), is considered the most optimal in reducing waste generation and increasing management efficiency. This scenario successfully forms a multi-loop circular chain system that minimizes waste, maximizes resource utilization, and shifts the paradigm from waste management to resource management. The resulting model is expected to be a strategic reference for local governments in formulating long-term policies towards sustainable waste management.

The Influence of Economic Value and Environmental Threat on Waste Management Behavior Among University Students

/in /by

This study investigates the role of economic value and environmental threats in influencing waste management behaviors among Generation Z online shoppers. The rapid increase in e-commerce activities has led to a significant rise in packaging waste, particularly plastic, posing severe environmental threats. This research aims to understand how perceptions of economic benefits and environmental threats drive waste management behaviors, with a focus on engagement levels as a mediating factor. The research employs a quantitative approach, using surveys distributed to Generation Z online shoppers in Java and Sumatera, Indonesia. The data reveals that both economic value and environmental threats significantly impact waste management behaviors. Specifically, economic incentives and financial rewards encourage better waste management practices, while heightened awareness of environmental threats drives individuals to adopt sustainable behaviors. The level of engagement plays a crucial mediating role, enhancing the effects of both economic value and environmental threats on waste management behaviors.

Implementation Strategy “3R CIRCULAR ECONOMY” To Achieve SDG Target 11.6 “Municipal Waste Management” In Cipaganti Village, Bandung City (Study at the Cihampelas Mandiri Unit Garbage Bank)

/in /by

Good municipal waste management is very important for a sustainable urban order. Good municipal waste management can reduce negative impacts on the environment, public health and natural resources. The application of a Garbage Bank is one of the solutions for good municipal waste management. This is due to the concept of a Garbage Bank which is aligned with sustainable city management. One of the principles that is effective in helping the performance of waste management at the Garbage Bank is a circular economy based on 3R (reduce, reuse, and recycle). The application of this concept needs to be supported by campaigns involving various activities such as outreach, education, training and promotion which aim to increase public awareness about the importance of sustainable waste management. This study aims to examine the Garbage Bank campaign strategy as an effort to support the achievement of Target 11.6 of the Sustainable Development Goals (SDG), namely “Urban Waste Management”, by implementing a 3R-based circular economy approach in Cipaganti Village, Bandung City. This study uses a qualitative approach with a case study method of a Garbage Bank in Cipaganti Village, Bandung City. Data was collected through in-depth interviews, participatory observation, and analysis of related documents. The key informants in this study were community members, related stakeholders, and the management of the Waste Bank in Cipaganti Village. The results of this study are expected to provide a better understanding of the effectiveness of the Garbage Bank campaign strategy in realizing SDG Target 11.6 in Cipaganti Village, Bandung City, as well as provide guidance for the government and related organizations in planning and implementing sustainable waste management activitiesgovernment and related organizations in planning and implementing sustainable waste management activities.

Penta Helix Partnership Program to Increased Waste Management Based on SDG Target 11.6 “Handling the City Waste” in Coblong District Bandung City

/in /by

Sustainability Development Goals (SDGs) are one of national and global efforts to maintain and create a clean and safe environment. However, the increasing amount of waste, especially in the city of Bandung, means that this criterion is broken. The community’s daily waste production is still high, causing waste to continue to pile up. Ironically, with the population of Bandung City being quite large and dense, especially in Coblong District, the TPA around Bandung City is no longer able to accommodate waste from Bandung City. As a result, the rubbish was simply abandoned on the side of the road. However, this waste problem is not the responsibility of just one party. This waste problem is a problem that requires cooperation from various parties called Penta Helix consisting of Academics, Business, Community, Government and Media. This research was conducted using explanatory qualitative research methods. With the aim of finding out how Penta Helix collaborates in realizing waste management in realizing the SDG 11.6 target in Coblong District through analysis from five points of view of the Penta Helix pillars. Because in dealing with this problem, multi-party cooperation is needed so that its implementation can be realized well and the impact given is more comprehensive and maximum. The result is that the collaboration between Penta Helix pillars is still not synergistic and the efforts shown, especially by the Government, are still not serious. Like waste that has been sorted and mixed again at the landfill, existing regulations are still minimally enforced and the human resources involved still do not meet the standards they should be. Then, the basic problem experienced by all the pillars in Penta Helix is the lack of community ability in sorting and managing waste from the household.

Vermicomposting in Silver Oak Plantation Areas for Sustainable Waste Management and Enhanced Livelihood: A Case Study of Kolli Hills, Tamil Nadu, India

/in /by

Silver Oak plantation on farmlands growing coffee and black pepper has gained importance in recent times in the areas surrounding the Kolli hills in the Namakkal district of Tamil Nadu, India. The Silver Oak trees shed significant quantities of dry leaves during the summer season which the local Malayali tribal community burns and/or leaves on ground. The current case study is based on an experiment of vermicomposting using local Silver Oak leaf litter, cow dung and earthworms. The results show that joint production of manure from agroforestry practices is an option in self-sufficiency for the rural communities and has the potential for a business model. Moreover, this ensures environmental sustainability by avoiding green-house gas emissions that are caused by the practice of burning leaves and/or leaving the mulch to rot. The present paper attempts to develop a sustainable model of vermicomposting in the Kolli hills region that can offer triple solutions encompassing organic manure production, environmental quality improvement and livelihood opportunity enhancement. Based on field surveys and physiochemical experiments in the Perungiraipatti village of the Kolli hills, the study presents a sustainable model of vermicomposting with specifications on nutritional quality, environmental sustainability and economic development.
