Abstract
This study was conducted to determine whether the backpack’s load of sixth grade elementary school students has exceeded the recommended load limit and to design an ergonomic backpack based on the ideal weight of the backpack’s load. The data were obtained using anthropometry and interviews with 70 respondents of 6th grade elementary school students in Bandung. It is known that the average of backpack load has exceeded the limit based on previous research has done to 10% of the child’s weight can caused musculoskeletal disorders in shoulder and back parts, so in this study a backpack was designed ergonomically based on the ideal weight of a backpack by converting 10% of the average weight of the students into the backpack capacity. The conversion result is combined with anthropometric data to determine the dimension of backpack, which is 35 x 25 x 6 cm. Backpack equipped with some additional features such as front pocket, back pads and chest straps as well as waist straps. Finally, this study showed the design of an ergonomic backpack for sixth grade elementary school students, where the capacity of the backpack is conditioned to not carry loads that exceed the ideal weight of a backpack.
Highlights
Previous research has been conducted by Amiri et al [4] to design an ergonomic backpack with the User Centred Design method [4], but the design of the backpack is done without regard to the ideal weight, so this study will consider the ideal weight of backpack load in the design of the backpack
Student backpack weight measurement is done by weighing student's weight when carrying school backpack and weighing student weight without carrying backpack, so that student backpack weight is obtained from the difference
While the students backpack weight measurements, interviews with the students were conducted with the help of the body chart of the Nordic Body Map, so that the students just pointed to the number of body parts where the students felt ill when carrying their school backpack
Summary
There are a lot of researchs is done to overcome the phenomenon students heavy bags that occur concerns about the development of the child's body. Other studies have been conducted to examine the effect of school bag weight on body health, proving that there is a significant relationship between bag weight and lower back pain in primary school children [2]. This study was conducted to find out whether the condition of backpack weight of sixth grade elementary school students have exceeded the recommended load limit and design an ergonomic backpack based on the ideal weight of backpack load. Previous research has been conducted by Amiri et al [4] to design an ergonomic backpack with the User Centred Design method [4], but the design of the backpack is done without regard to the ideal weight, so this study will consider the ideal weight of backpack load in the design of the backpack. This research conducted for sixt grade elementary school student
