Abstract

CV. XYZ is a manufacturing company in East Java that produces various types of concrete, including concrete roof tiles. The contract work system with half-day work hours often causes production targets to be missed, especially for workers who excuse themselves due to illness. This condition has an a impact on increasing the pysical and mental workload using a cardiovascular load (CVL) method and the mental workload using NASA-TLX. The results show that worker 3 at the roof tile printing station 1 had that highest %CVL value, namely 70,53%, and decreased to 59,25% after improvements were made. Meanwhile, worker 4 at the roof tile printing station 2 obtained the highest NASA-TLX score of 80,33, which then decreased to 72,33. This study recommends increasing discipline in the use of PPE and placing workers according to age to improve working conditions.

Abstract

This study analyzes workload and determines the optimal number of workers on the pond machine production line at UD. XYZ  using Workload Analysis (WLA) method and stopwatch time study. Data were collected through direct observation of 7 workers with 24 observations per work station during July-November 2025. The results show significant workload imbalance: the blade board manufacturing station experienced 446% overload, pond processes for Ivory 310, Duplex 350, and Duplex 310 were 185%, 191%, and 192% respectively, while plano paper cutting, QC cleaning, and packaging stations experienced underload below 75%. Standard time for pond processes ranged from 7.79-8.01 minutes. The study recommends adding 3 workers (total 10 people) with optimal redistribution to reduce workload to 46-111%, saving operational costs of Rp 10,368,000 per month (27%) while increasing productivity to achieve the target of 2,000 units per day.

Abstract

The increasing demand for glass cabinets at CV. Nanda Jaya has intensified the workload on the production line, leading to inefficiencies such as delays in order completion and potential worker fatigue. This study aims to analyze workload and determine the optimal number of workers at each workstation using the Work-Load Analysis (WLA) method. Data collection was conducted through direct observation, work-time measurement, heart rate monitoring using the Heart Rate Reserve (HRR) method, and uniformity and adequacy tests. The results indicate an imbalance in workload distribution, with the assembly station recording the highest standard time of 126.60 seconds, making it the primary bottleneck in the production process.

Abstract

Soybeans are an important food ingredient in Indonesia and are the main ingredient in making tempeh. Mr. Mahmudi's tempeh MSME in Sidoarjo has difficulty meeting market demand because the soybean peeling process is still done manually, resulting in slow production and less than optimal results. This study aims to design a more efficient soybean peeling machine and measure productivity increases after its implementation. The design process was carried out through literature studies, field observations, interviews, and data analysis, including worker anthropometric data to ensure the machine is ergonomic and safe to use. Test results showed that the machine was able to peel 8 kg of soybeans in 1 minute 9 seconds, much faster than the manual method which requires 8 minutes 23 seconds. Productivity increased by 628.9%, proving that this machine can significantly improve the efficiency, consistency, and production capacity of MSMEs.

Abstract

The Yos Sudarso Road section in Wolio District, Baubau City, is a major road with a strategic function, serving as the main connector between important centers such as the commercial area, Kamali Beach, and Murhum Port. The diverse land-use functions along this road generate high daily activity variations, which directly impact its traffic performance. Currently, Jalan Yos Sudarso is experiencing a decline in performance due to increased traffic volume and significant side friction from commercial activities. This research aims to analyze the traffic flow conditions and the Level of Service (LOS) of the road. The analysis method utilizes the Pedoman Kapasitas Jalan Indonesia (PKJI) 2023, based on primary data from surveys on road geometry, traffic volume, and side friction during peak hours. The traffic flow conditions reveal a very high level of side friction caused by on-street parking and vehicle maneuvers into/out of commercial establishments. This activity effectively reduces the road's effective width, consequently degrading its performance. During the peak hour (09:00–10:00), the number of side friction incidents reached 327 incidents per hour, with a concurrent traffic volume of 918.5 pcu/hour (passenger car units per hour). The analysis results show that the road section's actual capacity is 1,116.9 pcu/hour with a Degree of Saturation (DS) value of 0.82. This indicates congested flow conditions and a Level of Service (LOS) category D. This condition suggests that the road can still function, but it no longer provides an optimal level of service.
