Abstract

In the production process of EQ Spacing products at PT Sinar Semesta, it was discovered that there were eight types of defects which resulted in product defects exceeding company standards. The aim of this research is to carry out a series of analyzes and actions focused on controlling product quality and identifying various aspects that require improvement during the production process. The types of defects with the highest percentage include uneven surfaces at 35.3%, porous at 24.9%, and chipped at 19.3%. Using the Multivariate Exponentially Weighted Moving Average (MEWMA) approach with a weight of 4.05, shifts were found in periods 6, 10, 11, 12, 13, 14, and 15 of the MEWMA graph, with a DPMO value of 24268 and a sigma of 3.5. This analysis demonstrates that in order to prevent excessive defects, production process performance must be improved. PT Sinar Semesta must suggest modifications based on the 5W+1H approach in order to lower the quantity of flaws in bag products. The goal of this quality improvement is to get closer to zero defects and a very low failure rate. It is intended that by doing this, the final product will be superior and satisfy the company's quality requirements.

Abstract

Time measurement is carried out to determine the length of time required for workers to complete the production process, starting from raw materials to finished goods. Due to the low production volumes, the Barokah Tegal Tempe Home Industry's tempeh production process is not producing optimal results, which prevents them from fulfilling customers’ demands. Limited production capabilities due to lengthy processing times. Extended processing durations may result from non-value-adding movements or activities, as well as manual labor techniques. The aim of this research is to examine the tempe production process, with a focus on the three primary work stations—the peeling, washing, and mixing operations. The method used is the Maynard Operation Sequence Technique (MOST), where measurements are carried out on existing conditions and proposed work improvements. The research results show that the existing time measurement in the peeling process is 104,840 Time Measure Units (TMU), washing 316,020 TMU, and mixing 127,360 TMU. In order to reduce processing time, work tools should be able to do away with pointless movements. The proposed work improvement time for peeling process is 60,680 TMU, washing 93,800 TMU, and mixing 50,300 TMU. Calculations of the existing condition and proposed improvement can result in a 62% increase in working time efficiency.

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.
