Refurbished products, which are repaired or restored to a like-new condition, offer a more sustainable alternative to new products by extending their lifecycle. However, the marketing of refurbished products faces several chal-lenges, including consumer perception, trust, and the impact of carbonemission-constraint policies. This study aims to address these challenges and provide recommendations for effective marketing strategies. We explore the marketing of refurbished products within the context of carbon-emission-constraint policies, specifically comparing offline and online channels. We present two channel models, with the first model, referred to as Model O, fo-cusing on marketing refurbished products through the manufacturer’s own e-commerce channel. The second model, known as Model T, explores the al-ternative approach of outsourcing the marketing activity to a third-party en-tity. Carbon-emissionconstraint policies impose restrictions on businesses’ carbon footprint, affecting their marketing strategies. Businesses must navi-gate these policies while effectively promoting refurbished products to envi-ronmentally conscious consumers. By addressing the challenges faced in marketing refurbished products with carbon-emission-constraint policies, consumer behavior, and comparing offline and online channels, this thesis aims to provide valuable insights for businesses and policymakers to effec-tively promote sustainable consumption and contribute to a more environ-mentally conscious industry.

To advance the circular economy, refurbishing activities are essential to mitigate industrial waste. While cap-and-trade policies regulate greenhouse emissions, their mathematical interactions with refurbishing distribution strategies remain under-researched. This study assesses the implications of distribution structures on profitability under environmental constraints. Two multivariable optimization models were developed: Model C (direct distribution) and Model M (indirect distribution via a retailer). Objective functions were optimized for price and production volume under cap-and-trade constraints. A sensitivity analysis of 15 parameters employed partial derivatives to determine the profit function's rate of change relative to market potential (Q), price elasticity (λ), cannibalization (β), and carbon costs. Model C yielded a higher optimum value ($165,796) than Model M ($124,341). Sensitivity analysis identified Q as having the highest positive gradient. Conversely, profits exhibited high sensitivity to λ and β, where incremental coefficient increases led to non-linear margin deterioration. Mathematically, optimal pricing proved nearly inelastic to carbon price fluctuations, suggesting that production costs and demand coefficients dominate the profit function's Hessian matrix. Model C maintained lower pricing for new ($370,219) and refurbished items ($220,163) compared to Model M ($555,109 and $330,081). This study demonstrates that direct distribution mitigates “double marginalization” in multi-tier chains. Mathematically, firms should prioritize optimizing market parameters (λ, β) over carbon-cost mitigation. Furthermore, policymakers must recognize that cap-and-trade programs may drive industries toward vertical integration to achieve mathematical optimality.

Strategic borderlands and regional development In strategic border regions,?we find a complex politico-geographical dynamic between the imperatives of state territorial security on one hand, and economic under-development on the other. It’s about Natuna?Regency, Indonesia's "front-door" in the North Natuna Sea, which is emblematic of the unique paradox of high resource potential and long-standing development lags. The research examine 77 village units in Natuna to investigate regional development trajectories through Gunnar Myrdal’s perspective of Circular and Cumulative Causation (CCC), exploring the mechanisms of economic “locking” mechanisms of borderland economy. The methodology employs an advanced?k-prototype clustering algorithm to interpret high-dimensional Podes 2025 secondary data. This model uses mixed-type variables (i.e., digital, infrastructure or the presence of BTS and signal strength), economic facilities (credit access/KUR) as well as environmental?risk factor to analyze spatial-economic disparities. The analysis reveals three clusters-Growth Poles (Bunguran Timur), with a?"virtuous cycle" of digital-institutional synergy, The Agricultural Periphery in the form of a "backwash effect," associated with logistical bottlenecks, and Isolated Maritime Units facing cumulative decay. The study reveals that borderland resilience cannot be solely attributed to physical infrastructure but to the management of the compounded effect of innovation. The present research provides a strategic blueprint for sub-national governance to harness secondary data for policy-making in critical maritime areas.

Most of the people of Manukan village, Bojonegoro regency, have livelihoods as farmers or as farm laborers. Floods that always come in every rainy season have destroyed hectares of rice fields ready for harvest. This is what causes poverty in Manukan village to be difficult to overcome. However, since the new irrigation system was discovered for rice farming in Manukan village called the Arealan System, precisely since 1997 the condition of community welfare in Manukan village gradually lifted. The use of agricultural systems in crops in terms of quality and quantity can be significantly improved.The purpose of this research is to know how far the role of paddy farming Arealan to poverty alleviation in Manukan village. The results of this study indicate that using the paddy system of farmers in Manukan village can increase rice yield in terms of quality and quantity. So with the increase in the quantity and quality of rice produced will increase the income obtained by farmers.
