Abstract

Performance measurement method, Performance Prism, was used to improve performance measurement method in this furniture company. Until now, performance measurement system in this company  haven’t represented overall organizational performance since it only used performance measurement based on individual ability. Performance measurement using Performance Prism method was used because it could reflects the needs and desire of each identified stakeholder within company. This performance measurement is an integrated measurement, encompassing all company aspects (stakeholder) which related with stakeholder satisfaction and stakeholder contribution for the company. Performance measurement in this study also supported by several other methods such as weighting with Analytical Hierarchy Process (AHP) to determine priority scale of each KPI, Scoring System using Objectives Matrix (OMAX) and Traffic Light System to determine total index value of company in corporation level and category of those indices. Results of performance measurement in this company using Performance Prism indicated 79 KPI’s consist of 17 KPIs on Investor perspective, 16 KPI’s on Customer perspective, 16 KPI’s on Employee perspective, 15 KPI’s on Supplier perspective and 15 KPI’s on Regulator perspective. Based on performance measurement calculation using Objective Matrix and Traffic Light System, it obtained total index value 5,8364. This showed that performance of this furniture company  still yet to reach desirable performance thus it would need some improvement in this matter.

Abstract

Small and middle enterprises  have been the important part of the economic of a nation or a local. Karang Write-Batik is one industrial center which is located at Karang Village, Semanding Subdistrict, Tuban District. Early observation shows that various processes within the production of Write-Batik are conducted without considering ergonomic aspects, such as work method and work facility. It may result in complaint and even muscle injury which is called Musculoskeletal Disorders (MSD’s) Many pronlem of pain perceived by workers are caused by less ergonomic work position or work posture. It may also be evident because the less correspondence between work equipment and workers’ anthropometry size. To measure workers’ musculoskeletal injured, the author uses Standard Nordic Questionnaire (SNQ) and to assess work posture, Quick Exposure Check (QEC) is used. The reduction of workers’ musculoskeletal injuredt can be realized by improving work facility based on workers’ anthropometry size. Result of early measurement of exposure level of several parts of body indicates that the exposure level of the back is 26, while that of the arm is 30, that of the hand wrist is 26, and that of the neck is 16. After the improvement of work facility, workers’ complaint is reduced and so is exposure level. The exposure level with the improved work facility is shown as follows: the exposure level of the back is 22, while that of the arm is 22, that of the hand wrist is 22 and that of the neck is 14.
