Abstract

The Covid-19 outbreak has caused economic downturns and recession. In 2021, Covid-19 cases in Indonesia has a significant increase. The construction sector in Indonesia faced substantial challenges due to the pandemic, evidenced by contracted growth. The impact of the Covid-19 pandemic on the construction industry cannot be viewed solely from an economic perspective but must consider various factors. Issues in the construction industry affect project performance. Previous research could not interpret the relationship between individual pandemic impacts and project performance levels. Therefore, this study aims to determine factors Covid-19 pandemic affects construction project performance in Indonesia. The study identifies five factors that may influence project performance: (1) challenges in implementing social distancing, (2) movement restrictions, (3) challenges of working from home (WFH), (4) planning for worker limitations, and (5) use of personal protective equipment (PPE). Data was collected using questionnaires distributed to project managers in the construction industry. Primary analysis was conducted using Partial Least Square (PLS). The results indicate that three variables significantly impact project performance in the construction industry. The level of movement restrictions during the pandemic (lockdown) and the planning for worker limitations negatively affect project performance, while movement restrictions positively affect the challenges of implementing social distancing.

Abstract

One of the home industry conventions warsito in the Pati area produces clothing products like pyjamas. This home industry is run by individuals or families on a small scale. Convex home industries often face the challenge of managing efficient production processes and meeting consumer expectations. Faced with such challenges, they often face problems of waste in the production process, such as excessive inventory, waiting times, unnecessary movements, and inefficient processes. Therefore, to eliminate such waste, the concept of lean manufacturing is needed. This research discusses waste reduction using the Value Stream Mapping (VSM) and Waste Assessment Model (WAM) methods. With this method, non-value added identification is produced through the process flow and the relationship of waste to each other. There are 2 largest wastes, namely waste defect and waste motion, which then require improvement proposals by analyzing the causes/root causes of the waste using a fishbone diagram. From this method, waste defect with a percentage of 20.452% and waste motion with a percentage of 16.16%. The improvement proposal for dealing with waste defects is to apply the 5s principle, group materials by type and color, schedule machine maintenance. At waste motion it is recommended to set the work position, use aids such as jig, quality control of materials, set a sewing machine calibration schedule.

Abstract

Work in the current industrial era, both on a small to large scale, almost always carries a risk of danger. One of them is an occupational disease caused by errors in posture when doing work. Illnesses caused by work posture errors usually do not have an immediate effect after finishing the job, but sometimes the impact often appears after quite a long time. Body posture is a determinant in assessing effectiveness at work. If the employee's posture is ergonomic then the results of the work will be good and the health of the workers is guaranteed. However, if the employee's posture is not ergonomic, then the results of the work are not necessarily good and can cause complaints on the body. In this study aims to analyze the performance posture of an employee in the quality control division. The method used is to use the nordic body map questionnaire and RULA calculations. The results obtained from the nordic body map questionnaire are that it can be seen which part of the body experiences pain, namely the upper body posture. While the results obtained from the RULA calculations were on the work of wiping components and checking data on the computer, the grand score obtained was 4, which means that it needs further investigation and if necessary repairs are made. Meanwhile, for the work of polishing components and measuring components, a grand score of 7 was obtained, which means that it needs to be investigated and repaired right away.
