System dynamic models have been recognized as an effective approach in projecting and designing sustainable urban waste management systems. This study aims to explore the potential of system dynamic modeling in urban waste management. This study uses a literature study method with a qualitative descriptive approach that refers to various relevant previous studies. The results of the literature study show that the system dynamic model is able to map the complex relationships between variables in the waste management system, such as population growth, waste production, waste processing capacity, environmental impacts, and others. In addition, the system dynamic model can project future waste management conditions and prepare the most effective policy scenarios. Through simulations of various policy scenarios, the system dynamic model can provide insight into the impact of each scenario, both in terms of technical efficiency, operational costs, and reduction of waste generation in landfills. In implementing policy scenarios, collaboration between the government, community, and stakeholders is also needed in optimizing waste management programs.

Companies often face various obstacles related to managing raw material inventory to meet demand, one of which is Peuyeum Ketan Istimewa. Working in the food processing industry, of course, raw material inventory management needs to be planned optimally to avoid various risks that can harm the company. The Quantity Discount model is used to take advantage of cost savings provided by suppliers when purchases are made in large quantities, while other efforts that can help manage raw materials in a company are by knowing the safety stock and reorder point of raw materials and also forecasting demand to predict future demand. This study will use the Quantity Discount model which optimizes inventory levels by considering storage costs, ordering costs, and quantity discounts. The calculations carried out are also to find the value of the company's Safety Stock and Reorder Point. The results of this study indicate that the use of the Quantity Discount method can reduce total costs by Rp26,319,267/year, while forecasting using the seasonality method increases the accuracy of demand predictions, thus enabling more efficient inventory management. The implementation of this model is expected to provide a significant contribution to operational efficiency and cost reduction at Peuyeum Ketan Istimewa

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.

Agro-industry is a strategic sector that supports rural economic growth and food security. Agro-industry, as a strategic sector, often faces challenges in financial management, which have an impact on business stability and sustainability. This research analyzes the financial performance of the Tahu Bulat Putra Mandiri Agroindustry in Ciamis Regency based on liquidity, solvency and profitability ratios. Financial report data for the last three years (2022-2024) was analyzed using the case study method by calculating financial ratios, such as current ratio, quick ratio, debt to asset ratio, debt to equity ratio, return on assets (ROA), and return on equity (ROE). The results show fluctuations in financial performance, where the liquidity ratio is good enough to meet short-term obligations, but solvency reflects high financial risk due to dependence on debt, while profitability experiences a decrease in efficiency in generating profits. This research recommends improving capital structure, increasing operational efficiency, and business diversification to ensure the company's financial sustainability and stability.
