This thesis contains the relationship of risk factors for manual material handling (MMH) with complaints of subjective musculoskeletal symptoms (MSS) to workers in the Department of Textile Chemical Production of PT. X in 2020. In this study, observation of manual risk handling (MMH) risk factors is using questionnaires and the Quick Exposure Checklist (QEC) method. Besides, to find out complaints about musculoskeletal symptoms (MSS) researcher used the Nordic Body Map (NBM) Questionnaire. The study design is a cross-sectional study with an observational approach. The analysis used in this study is univariate and bivariate analysis. Univariate analysis is used to provide an overview of each risk factor for manual material handling. While bivariate analysis is used to see the relationship between individual risk factors (age, years of service, body mass index, exercise habits, and stress) and work risk factors (object weight, work duration, and work posture) with musculoskeletal symptoms (MSS) complaints that felt by workers in the Textile Chemical Production Department of PT. X in 2020. The results of this study found that there is a relationship between body mass index (BMI) with complaints of musculoskeletal symptoms (MSS) felt by workers (pvalue = 0.040). In addition, there is a relationship between work stress and musculoskeletal symptoms (MSS) complaints felt by workers (p-value = 0.044).
This study presents our investigations of ergonomic factors that related to Indoor Health and Comfort/IHC (with indicators Sick Building Syndrome (SBS) symptoms and work comfort) and Musculaskeletal Symptoms (MSS) suffered by functional and staff workers in Office X year 2017. Conducted in X Office in Indonesia, with the object study are functional and staff workers who work using computer or laptop in staff room which cubicle type (room A, B, C, D, and E). This study perform via walktrought observation, interview, measure indoor air quality/environment factors and fill indoor comfort quesionaire, SBS symptoms quesionaire and Nordic Body Map (NBM) quesionaire . 53,85% of workers have a high level of work comfort and 46,15% of workers have a low level of work comfort. 53,85% of workers suffered complaint of SBS symptoms with at most complaint of SBS symptoms be found are 33,85% tired or strained eyes and 33,85% fatigue or drowsiness. 78,57% of workers suffered MSS complaint. Ergonomic factors that not comform to standard include seat dimensions, table dimensions, computer used, work posture, room dimensions, room layout, room colors, and noise, lighting, temperature, humidity, carbon dioxide , formaldehyde, and VOCs. There is significant relationship between activity level factors and work comfort; VOCs concentration and complaint of SBS symptoms. There is no significant relationship between ergonomic factors are studied and MSS complaint.

MSDs sering dialami oleh pekerja perkantoran karena banyak menghabiskan waktunya
untuk melakukan pekerjaan statis. Di PT X, keluhan terkait MSDs seringkali muncul, namun PT X belum melakukan pengukuran terkait dengan risiko ergonomi dan MSDs sejak periode September 2021. Tujuan dari penelitian ini adalah untuk mengetahui gambaran tingkat keluhan MSDs PT X dan apakah ada hubungannya dengan faktor risiko individu (usia, jenis kelamin, aktivitas fisik, dan IMT) dan postur kerja. Hubungan di antar variabel diuji menggunakan uji spearman. Faktor risiko yang berhubungan signifikan adalah faktor risiko individu IMT dengan P value = 0.018 dan koefisien korelasi -0.41 yang menandakan arah hubungan negatif dengan kekuatan hubungan cukup. Arah hubungan negatif berarti adanya hubungan terbalik di antara IMT dan tingkat keluhan MSDs. Semakin tinggi IMT, kemungkinan untuk mengalami MSDs akan semakin rendah.
MSDs is closely associated with those who works office job as they spent most of their time sitting in the same position. At PT X, MSDs complaints frequently occurred, however, no ergonomic assessments have been conducted since September 2021. This study aims to get the general level of MSDs complaints among office workers at PT X and to examine whetere there is a relationship between the level of MSDs complaints and individual risk factors (age, gender, physical activity, and BMI) as well as working postures. The correlation between variables were tested using the Spearman correlation test. BMI was found to have a significant relationship with MSDs with a p-value of 0.018 and a correlation coefficient of -0.41 that indicates a moderate negative relationships. This outcome suggests that those with higher BMI, have a lower likelihood to experience MSDs
