Abstract

Product design has emerged as a crucial element in developing innovative solutions that prioritize not only functionality and aesthetics but also sustainability. The Human-Centered Design (HCD) approach has long been employed to ensure that user needs remain the primary focus throughout the design process. However, global challenges such as climate change, social inequality, and the long-term impacts of products necessitate a more comprehensive approach. Consequently, the concept of Humanity-Centered Design has been developed as an extension of HCD, emphasizing the importance of considering the entire ecosystem, other living beings, and long-term consequences in the product design process. This research utilizes a narrative literature review method to examine the Humanity-Centered Design (HuCD) approach within the context of sustainable product design. The review findings indicate that Humanity-Centered Design introduces five key principles, which include a focus on fundamental issues, a holistic ecosystem perspective, long-term outlook, continuous iteration, and community participation. This approach has been shown to enhance the relevance, acceptance, and sustainability of solutions across various sectors, including health technology, manufacturing, and digital domains.

Abstract

This study examines the performance of a three-phase decanter centrifuge in separating oil, water, and solids in palm oil mills. Efficient separation is critical to improving crude palm oil (CPO) yield and minimizing losses, yet many mills face challenges such as excessive sludge, unstable emulsions, and oil loss. The objective of this research is to compare the operational performance of decanters at A and B mills and to identify the dominant factors influencing oil loss. A case study approach was employed, combining sampling of light, heavy, and solid phases with operational data analysis and direct observations. The results indicate that PKS A experienced high non-oil solids (NOS) in the feed, which caused excessive oil loss in the sludge, while PKS B faced unstable and high emulsion levels, resulting in greater oil loss in the heavy phase. These findings confirm that decanter performance is highly site-specific, even when identical machines are used. The study concludes that operational strategies must be tailored: reducing NOS in PKS A and controlling emulsions in PKS B. The main contribution of this research is providing empirical evidence of differing decanter challenges across mills, offering practical guidance for optimization. The limitation lies in the scope restricted to two mills, suggesting that future research should include more sites and external variables to develop a comprehensive optimization model.
