Abstract

Slouching and squatting work postures in the fish cleaning process can cause skeletal muscle injury. Based on the results of previous research conducted by Adelia (2020), the results of the existing NBM show that workers have complaints in the muscles of the neck, arms, back, waist, buttocks, hands, wrists, thighs, knees, and feet. The result of total muscle complaints individual skeletal is 75, meaning that the existing work posture requires work improvement. Improvement of working posture can be done by designing work aids in the form of desks and chairs. The determination of the MSDs risk level category was carried out by identifying the skeletal muscle complaints felt by workers using a Nordic body map (NBM) questionnaire, a working posture assessment was carried out to determine the score level in work posture using the Rapid Upper Limb Assessment (RULA) method with the help of CATIA V5R20 software. Assistive devices in the form of desks and work chairs are designed based on complaints experienced by workers and use the anthropometric approach in determining the dimensions of work aids. Based on the results of the implementation of work aids, there was a change in the score for skeletal muscle complaints and work posture. The results showed that the average NBM value of individual muscle complaints was 56.75, this is included in the moderate risk level and the results of the RULA analysis on the repair work posture experienced a change in the final score, namely 4 (yellow).

Abstract. The purpose of this study is to analyze the determination factors ofcapital structure, such as deficit, profitability and tangibility asset, and theirinfluence to the use of short term debt, long term debt and total debt, based on twoperspective namely Pecking Order Theory (POT) and Trade-off Theory (TOT).From the perspective of POT, company has a certain order to choose theirfinancing decision. The order start from internal to external financing. Thus, inPOT, deficit has positive influence to the debts while profitability and tangibilityasset have negative influences. From the perspective of TOT, debts are able toprovide advantage to offset the tax value. Thus, based on TOT, deficit,profitability and tangibility asset have positive influence to the debts. The samplesof this study are 10 manufacturing companies listed in LQ45 for minimum of fourperiods in 2010-2014 with OLS Regression as the analysis method. The resultsimplied that in terms to the use of short term debt and total debt, financingdecision of sample companies has no path suggested by POT nor TOT; however,regarding the uses of long term debt, the companies follows the path suggested byPecking Order Theory.Keywords: Deficit, Profitability, Tangibility Asset, Debts, Pecking Order Theory,Trade-off Theory
