Using ergonomic orthopaedic chairs can address spinal issues, particularly HNP, due to their flexible and elastic properties. By achieving optimal ergonomic design, various positive aspects can be achieved, such as increasing work quality productivity and reducing the cost of injuries or accidents. This research demonstrates diverse product design approaches to enhance posture health ergonomics, address specific musculoskeletal disorder issues, and consider local needs and available materials. Rattan is a tropical vine widely used in the furniture industry and predominantly found in wooded areas such as Indonesia. This research combines market research, morphology, ergonomic study, concept selection, QFD, HoQ, stiffness test, and prototype review. The QFD method was chosen in this study due to its excellence in connecting consumer desires with the product development process. Data of respondents consist of 51 % of respondents were male, 49 % were female, 88 % were aged between 18 and 34 years old, and 10 % were aged between 35 and 54 years old. The approach of 6 stages of product design as the primary framework for developing our product such as: planning, concept development (concept screening, product morphology, concept selection), system-level design, detailed design, testing, refinement and launching. Based on the calculations using the HOQ, it is identified that the primary focus in designing the rattan-based orthopaedic seating, lies in the orthopaedic design that provides maximum comfort for the spine. The comparison results indicate that the stiffness level of rattan weaving is nearly like latex, with a similarity percentage of 89 %. Data analysis using the QFD method indicates that the primary priority aspect is the orthopaedic design, followed by the selection of quality materials, cost-effectiveness, versatility, and appealing design aspects. Rattan's superior air circulation provides comfort by preventing excessive heat accumulation, excellence in strength and durability, ensuring ease of lightweight modelling, and providing more sustainable material.
This research was conducted on industrial agriculture in Indonesia. Risk analysis was carried out based on previous research. One source of risk was obtained, namely raw materials that did not meet specifications, which was then proposed to be mitigated by evaluating supplier performance. This activity involves a lot of data, requiring efficient and effective data storage and access. The level in the simulation layout includes analysing system needs, using problem diagrams, compiling activity diagrams, deciding subprocesses, and filtering information. The analysis is carried out by comparing the use of supply chains with Blockchain and without Blockchain, which is then obtained to determine whether there is an increase. A sequentially stored data scenario describes a situation when the transaction process is in progress and is stored sequentially according to the process that occurs. Storing data in groups explains a problem when a transaction has been completed and stored in groups with similar data, making it easier to track specific data. In this regard, a simulation will be carried out using a website, namely a blockchain demo. The design stage starts with identifying system requirements, creating use case diagrams, compiling activity diagrams, determining subprocesses, and selecting information. The simulation results obtained will be analysed to determine the feasibility of Blockchain as a means of supporting risk mitigation related to data using aspects, including security, trust, traceability, sustainability, and costs.
