Abstract

A UNP-100 is a canal iron that connects the storage area (bin) to the frame of a truck. Therefore, the selection of UNP-100 suppliers is an essential process. Suppliers are chosen to provide high-quality materials, in-time deliveries, affordable prices, and excellent services, the applied analytical network process (ANP) in this study. The quantitative method is conducted through questionnaires, and the qualitative method is by interviews. After distributing the questionnaires, calculations are carried out to assess suppliers by constructing an ANP supermatrix. The respondents are the purchasing managers, the quality managers, and the PPIC managers. The criteria to choose suitable suppliers are packaging (0.060), price (0.212), customer care (0.712), delivery (0.103), and quality (0.351). The prioritized UNP-100 suppliers are PT. KPPE (0.346), PT. KPS (0.344), and PT. SME (0.31).

Abstract

A wheelchair is an essential mobility tool for individuals with limitations, including children with Cerebral Palsy (CP). Cerebral palsy affects children under five and causes stiffness in various body parts. The design of wheelchairs for children with CP differs significantly from standard wheelchairs, prompting this research to identify the key factors that should be considered in designing such wheelchairs. This study used exploratory factor analysis, data was gathered from children with CP and their caregivers in Java. The findings revealed six fundamental factors to consider when designing wheelchairs for children with CP: Main features, Ultimate comfort, standard compliance, robust durability, thoughtful ergonomics, unique special features, user-friendly design, and aesthetic appeal. In summary, while the main features are crucial in the design of wheelchairs for children with CP, it is equally important that these wheelchairs comply with applicable standards and incorporate special features tailored specifically for these young users.

Abstract

Cerebral palsy is caused by brain damage that manifests as motor dysfunction. The most prevalent form of cerebral palsy is spastic diplegia, which causes walking difficulties. People with cerebral palsy, particularly children, require mobility aids, such as wheelchairs, to perform daily tasks. When designing wheelchairs for children with cerebral palsy, ergonomic evaluation is required to ensure that the resulting wheelchair is safe and will not pose a risk in the future. This paper investigates the use of digital human modeling to evaluate the ergonomics of wheelchairs for children with cerebral palsy. The method is used to collect samples from 5 to 18-year-old children with cerebral palsy. Digital human modeling is used to simulate and evaluate ergonomics using anthropometric data. The results obtained for the wheelchair dimensions are suitable for the 95th percentile value, while the seat length exceeds the popliteal length for the 50th percentile value. The ergonomic evaluation yielded satisfactory results for the lower back analysis parameter, and the comfort evaluation yielded satisfactory results for the 95th percentile value. In contrast, the 5th percentile value indicates knee discomfort in both the right and left knee.
