Ergonomic portable toilet for women in public facilities

Abstract

Portable toilet is the type of toilet that can be moved easily. It usually has rectangular shape with walls made of fibreglass. Portable toilet is commonly produced for public use. In the designing process of portable toilet, there are some aspects that need to be taken for consideration, such as functional, aesthetic, cultural, and comfortability. To find out the lack of toliet design and complaints about the use of portable toilet, the distribution of open and closed questionnaires were conducted. The questionnaire also contains several questions about the user’s wishes. Once the result was obtained, validity test and reliability test are applied to examine the answers and later to create the base for the conceptual design. The design process has been carried out based on ergonomics principles. Dimension of the design is derived from anthropometric data of Indonesian women. The analysis tool being used in this research is Rapid Entire Body Assessment (REBA), to be implemented before and after improvement. Simulation has been done using CATIA software. The final product of the portable toilet design has hexagonal shape with 1600 mm x 2070 mm dimension, equipped with septic tank and water container that uses rain harvesting and solar panel innovation. Result of the simulation foresees a decrease in REBA score, from 6 (medium risk level) to 1 (low risk level).
