Abstract: BATACLAN, KAYE PATRICIA C. and SALVACION, REYLENE FAE F.. Risk Assessment and Development of an Ergonomically-Designed Portable Workstation for Shoemakers. Undergraduate Thesis. Bachelor of Science in Industrial Engineering. Cavite State University, Indang, Cavite. May 2018. Adviser: Ms. Mary Joyce P. Alcazar. Shoemaking is a high risk occupation for developing work-related musculoskeletal disorders (WMSDs). The study aimed to assess the risk and develop an ergonomically-designed portable workstation for shoemakers. The Define-Measure- Analyze-Design-Verify (DMADV) approach was used in undertaking this study. The define phase shows the determination of the demographic and anthropometric measurement of the shoemakers, the identification of the frequency and the severity of the work-related musculoskeletal disorders; the identification of the level of risk associated to the working posture of the shoemakers; the evaluation of the current workstation of the shoemaker, and the identification of the problem they experienced. A survey In the form of questionnaire was designed and administered as a pre-treatment measure to determine the necessary data needed on the study. Thirty (30) shoemakers were selected as participants. This study was conducted at selected cities and municipalities of Cavite only. The resulting average age was 44 years old, have an average normal Body Mass Index of 22.56, all were male and have an average working period of 8 hours. In terms of posture, Rapid Entire Body Assessment (REBA) was used. The assessment showed that the majority of the shoemakers (73.3%) were working at very high risk. The result calls for engineering and/or work method changes. The measure phase involves correlation analysis to determine if the current workstation has a significant effect on the development of WMSDs. Correlation analysis showed that the shoulder of the shoemaker experienced muscle pain and the arm experienced strain when there is no proper arm rest. In terms of back, the shoemaker's experienced muscle pain when there is no proper back rest. The legs of the shoemaker experienced nerve tension for having no proper chair. Lastly, the shoemakers also experienced muscle pain in the neck for having no proper table. The analyze phase shows the analysis of the considered factors through the identification of customer requirements and were evaluated with respect to the technical requirements using quality function deployment (QFD). Designing and developing a new workstation was the method done by the researchers to reduce the occurrence of WMSDs. For the design, the concept appearance and function of the product were based on the factors chosen in the analyze phase. The workstation was made to be ergonomically-designed for suitability purposes: it has a chair with foldable characteristics and table with extendable features for wider working area, made from standard materials for durability or good condition, and involves creative and unique feature for ease of use such as door panel with storages, rotational plantilya, pull bars and separate thread holder for easy sewing. The developed ergonomically-designed portable workstation for the shoemaker has positive feedback from the respondents. Although the chair got a fair rating, other factors got a high rating of good, very good, and excellent.
