This study aims to analyze waste management in Indonesia from 2001 to 2022, and identify challenges and solutions that can be implemented to improve the effectiveness of waste management. Waste is a major problem affecting the environment and public health, with around 34.29% of waste in Indonesia not being managed properly. This research uses a descriptive approach by analyzing data related to policies, infrastructure, and community participation in waste management. The results showed that although there are regulations governing waste management, the main challenges faced are low public awareness and limited waste management infrastructure in many regions. The research also found that collaboration between the government, communities and the private sector is crucial in creating sustainable solutions. In addition, the development of environmentally friendly waste management technologies, such as Waste Power Plants (PLTSa), can be an innovative solution to reduce the negative impact of waste on the environment. This research suggests the need to strengthen regulations, increase public awareness, and develop more efficient and environmentally friendly waste management technologies.

Effective agricultural waste management has a huge potential to increase community productivity and income. Agricultural waste, often considered a problem, can be processed into valuable resources such as organic fertilizer, biogas, and animal feed. By utilizing organic fertilizer from agricultural waste, soil fertility can be enhanced and dependence on chemical fertilizers can be reduced, thus contributing to increased crop yields. Biogas produced from the fermentation process of waste can be used as an alternative energy source, which in turn can reduce operational costs and increase income. Moreover, animal feed derived from agricultural waste can improve the quality and quantity of livestock production, which also contributes to changes in the income of livestock farmers. Additionally, good agricultural waste management can reduce environmental pollution and improve public health. Therefore, it is important to raise awareness and knowledge among the community about sustainable agricultural waste management practices. This needs to be complemented by adequate infrastructure and training so that waste can be processed into resources that benefit everyone.    

A collection of shoes that are not neatly arranged often makes you lazy to tidy up and clean them, whereas the condition of scattered shoes can spoil the view and reduce the durability and functionality of the shoes themselves. On the other hand, plastic waste, especially plastic bottles, is increasing and becoming a serious problem for the environment. In an effort to reduce the impact of pollution and utilize unused items, this study proposes a solution in the form of making a shoe rack from used plastic bottle waste. The use of plastic bottles not only reduces the amount of waste but also provides a practical solution for more organized shoe storage, especially for students who need efficient and environmentally friendly shoe storage space. The method used in this study is (R&D), which aims to develop a shoe rack product and test its effectiveness and feasibility. The test results show that this shoe rack can accommodate 12 pairs of shoes with a maximum strength of 5.5 kg per rack consisting of three levels. The use of 69 plastic bottles for the base and 24 bottles for the walls provides a large enough capacity to store shoes. Based on the test results, this shoe rack not only functions as a place to store shoes, but also as an effort to reduce plastic waste and support environmental sustainability. This product can also be used as an example in learning product design, recycling, and entrepreneurship.

Rock mining along the Bone River, Bone Bolango Regency, contributes to infrastructure development but also has negative environmental impacts. This study aims to analyze the effects of mining activities on river environmental quality, particularly water discoloration, erosion, river widening, and material accumulation. Data obtained indicate that mining activities cause water pollution characterized by discoloration due to increased sediment and mining waste. Moreover, rock excavation accelerates erosion along riverbanks, resulting in land degradation that affects the stability of surrounding areas. Mining activities also trigger river widening, altering the river's natural morphology and increasing flood risks. The accumulation of mining residues around the river worsens conditions by obstructing water flow, causing sedimentation, and damaging aquatic habitats. The analysis highlights the need for better environmental management to mitigate the adverse effects of rock mining. Recommendations include implementing strict environmental policies, monitoring mining operations, conducting reclamation, and ensuring sustainable waste management. Additionally, involving local communities in river rehabilitation efforts can expedite environmental recovery and sustain ecosystem balance. This study is expected to serve as a reference for policymakers in managing mining activities sustainably and preserving the Bone River ecosystem.

E The integration of Environmental, Social, and Governance (ESG) principles into e-procurement systems offers a pathway to achieving sustainable public procurement in Indonesia. This study explores relevant ESG criteria and formulates strategies to enhance the capacity of procurement personnel in implementing these principles. The findings highlight the importance of incorporating environmental criteria such as energy efficiency, eco-friendly materials, and waste management; social criteria like labor standards compliance, local MSME empowerment, and gender equality; and governance criteria including transparency, anti-corruption, and tax compliance. While e-procurement provides a digital platform to improve efficiency and transparency, challenges such as limited awareness, capacity gaps, and the absence of specific ESG guidelines hinder effective implementation. To address these issues, the study proposes strategic measures, including the development of ESG-based evaluation systems, comprehensive training programs for procurement personnel, and robust monitoring frameworks. These initiatives aim to align procurement practices with the principles of Sustainable Public Procurement (SPP), ensuring that procurement contributes to environmental sustainability, social equity, and better governance. By overcoming existing barriers and fostering collaboration among stakeholders, Indonesia can position itself as a leader in sustainable procurement practices. This research provides practical recommendations to integrate ESG into procurement systems, paving the way for a more accountable, equitable, and sustainable procurement framework.
