Abstract

WMSD frequently occurs in agriculture works, because the working conditions that require awkward posture in standing or sitting position as well as lifting and carrying heavy loads. Preliminary study showed that oyster mushroom farmers experienced pain in several of body parts especially their waist.  Therefore, this paper aims to evaluate the working posture of oyster mushroom farmers using AWBA (Agriculture Whole Body Assessment) and provide recommendation to reduce risk of musculoskeletal disorder. AWBA evaluates working posture and duration of upper (AULA) and lower extremities (ALLA). The result showed that activity of oyster mushroom production was risky, since 46,7% of all activities were categorized as “very high” and “high” level. Skor of AWBA posture correlated significantly with ALLA (0.812) and and AULA (0,56). Regression analysis showed that AWBA positively correlated with AULA and ALLA. Duration analysis showed that 86,7% working duration were classified as “very high”. The riskiest activity was harvested mushroom from top shelf. Furthermore, distribution and mixing raw materials, taking out baglog from sterilizer, harvesting mushroom from middle shelf, and packaging mushroom into plastic bag also risky activities, since the duration and posture measurement were classified as very high and high, respectively. Recommendation for reducing WMSD were redesigning working area and facilities of oyster mushroom production, such as design ergonomics baglogs’ shelves so that farmers position when reached the baglog was neutral, utilizing table and chair with suitable height in filling media into baglog, inoculation, releasing baglogs’ ring, and packaging activities.

Abstract

When Covid-19 emerged in Indonesia in early 2020, students had to learn from home to prevent the spread of the virus. The changing activity could effect on physical and mental health caused by student’s behavior during learning from home. Survey showed that 84% students of Industrial Engineering, Mulawarman University used smartphone while learning from home. Therefore, this study aimed to identify students’ behavior, to measure physical (i.e., musculoskeletal and visual fatique) and mental health (i.e., stress and smartphone addiction) problems that occurred when they were learning from home, as well as to suggest ergonomic recommendation for reducing the negative effects. At the time of the study, they were 155 students studied in the IE department and a total of 134 (86.45%) participated in the online survey. Musculoskeletal disorder was assessed using Nordic Body Map and visual fatique was evaluated using symptoms that were reported on previous studies. Additionally, Smartphone Addiction Scale (SAS) and Perceived Stress Scale (PSS) were administered to identify smartphone addiction tendency and stress level respectively. The results showed that MSD occurred in left and right shoulder (95%), followed by upper neck (82.14%) and back (72.62%). 86% of participants experienced visual fatique with headache (71.55%), ache eye (68%) and dry eye (60.34%) symptoms. Subsequently, this survey revealed that 35% of the participants addicted to smartphone and 68.66% experienced moderate level of stress. To alleviate these physical problems, several ergonomic recommendations were proposed i.e., supporting the arm that holding the smartphone with the other hand, practicing the 20-20-20 rule and applying stop, drop and flop slogan. Moreover, cooperation among parents, students and lecturers was needed to create conducive learning environment so as the mental health problems could be minimized.
