Habing Maragondon, established in 2017, produces handwoven textiles using manual handloom tools,
exposing weavers to ergonomic risks and musculoskeletal disorders due to repetitive motions and prolonged
discomfort. This study aimed to design and develop an ergonomic handloom weaving tool, employing the
DMADV (Define, Measure, Analyze, Design, Verify) method. The define phase found problems with the current
handloom tool that includes the weavers' discomforts. Anthropometric data and rapid entire body assessment
(REBA) evaluations showed in the measure phase that there is a medium risk on the tool, and it requires
modifications. In the analyze phase, problems were translated into customer requirements and prospective
solutions, and technical requirements were compiled using a tree diagram. Quality function deployment (QFD)
ensured alignment between customer and technical requirements. The design phase included the visual image
of the prototype along with its parts, comparison of the current and developed tools, bill of materials, and
standard operating procedures. The verify phase evaluated the prototype's features and quality, as well as
utilizing the following tools: REBA, time study, flow process charts, productivity, and cost-benefit analysis.
Results indicated that the ergonomic design significantly improved working conditions by reducing physical
stress and enhancing comfort during the weaving process. This study concludes that the ergonomically
designed handloom weaving tool offers substantial benefits, promoting better health and efficiency for
weavers. Keywords: Ergonomics, Handloom weaving tool, Semi-automatic weaving | Domain: Ergonomics

This study focused on developing a machine that will help tire technicians in vulcanizing shops lessen the
musculoskeletal disorders (MSDs) they experienced. The study gathered data through different registered
vulcanizing shops around four municipalities of the province of Cavite. By these data, problems encountered
by the tire technicians were identified and a technical requirement was made. These served as the
specifications in making the multi-functional machine. The results showed that constructing an ergonomically
designed machine lessen the MSDs, and assembling the machine a multi-functional increased the productivity
of the tire technicians and created a safe and comfortable workplace for them. Keywords: Vulcanizing Shops,
