Improvement of cinnamon (C. burmanii) sorting and grading through influencing factors

Abstract

Abstract Labour productivity influenced by work-in-process, labour skills, machineries and working environment. This study identified factors affecting the labour during sorting and grading of cinnamon. Five factors used as independent variables, namely working motivation (X1), working environment (X2), salary (X3), age (X4) and workload (X5). Factors then correlated with labour performance (Y) as dependent variable. Samples were randomly selected from respondents, of the Rasdi Fo & Co. Personal characterization calculated from employee’s years of service. Results then grouped according to the labour experienced, and statistical analyses were set according to F test, t test, power function, and influence factors. These methods used to analyse the working environment, in correlation to the employee performance, room temperature, humidity, lighting, and noise levels. From the results, X2, X3, X4 and X5 had no significant effect, while Y can be described as a function of 2,06(X10.326)(X20.016)(X30.170)(X40.479)(X5−0.172). Maximum room temperature recorded at 38.4°C, while minimum temperature recorded at 29.3°C, lower than the ideal level. Maximum and minimum humidity (RH) was 91.3 % and 59.2 %, respectively. The RH in working environment exceed normal level. The noise level recorded between 48.8 dBA and 78.4 dBA, which classified as normal without ear protection.
