Optimalisasi Kapasitas Stasiun Kerja dengan Metode Theory of Constraints (TOC) di PT. XYZ

PT. XYZ is a company that produces rims cars. One of the products produced is rims with ABC type. The production process carried out is make to order repetitive. PT. XYZ has a production capacity problem, causing an unfulfilled order. The production floor has a bottleneck work station at work stations 1 and 2. The accumulation occurs because of the standard time difference and the maximum capacity. This study uses the Theory of Constraints (TOC) method to deal with bottlenecked work stations. Calculating the maximum capacity of each work station results in work station s 1 and 2 having less capacity than the other work station. To solve the bottleneck problem at work stations 1 and 2, there are two alternative solutions, overtime and the addition of a work shift. After analyzing the existing problem, to solve bottlenecks at work station s 1 and 2, add the shift of work from 2 shifts to 3 shifts with an overtime of 1 hour per shift.

Lead (Pb) Exposure on Hemoglobin Levels and Decreasing Lung Function of Fuel Station Workers Banjarmasin

Introdution:Exposure to airborne pollutants such as lead (Pb) can cause health problems. Fuel stations are one of the places with a high risk of Pb exposure sourced from fuel or motor vehicle exhaust emissions. This research aims to know the effect of Pb exposure on hemoglobin levels and lung function in fuel station workers. Methods: This study was observational, analytical, and cross-sectional on 40 fuel station workers in South Banjarmasin District. Urinary Pb measurement was carried out by spectrophotometry, then the relationship to peripheral blood hemoglobin (Hb) levels and lung function was analyzed based on FEV1 (%), FVC (%), and FEV1/FVC ratio with a simple linear regression test. The data met the classical assumptions of normality, heteroscedasticity, and with no autocorrelation. If abnormal distribution was found, data transformation was carried out. Results: Study obtained urinary Pb levels below the normal threshold of 0.0356±0.0074 ppm. Respectively, urinary Pb levels did not have a significant effect on Hb levels (mean±SD:14.39±1.41, adjusted R2:6.2%, p=0.067), FEV1 (94.15±6.93, 5.8%, p=0.074) and FVC (89.68±6.24, 0.5%, p=0.380). However, urinary Pb significantly correlated with decreasing the FEV1/FVC ratio (90.87±3.36, 10%, p=0.026) with the equation y=96.550159.454x even without any obstruction value. Conclusion: This study showed that urinary Pb levels were normal. An increase in urinary Pb levels has a significant effect on decreasing the FEV1/FVC ratio. Prevention to reduce the health impacts of Pb needs to be taken. More research on at-risk populations with longer years of service needs to be done

B-Splined Trajectory Modified Generation to Maximize Speed of the Nonholonomic AMR Robot

Abstract: Trajectory path generation is critical for the Autonomous Mobile Robot (AMR) when moving frequently in the working environment in the shop floor to transport loads from one work station to another continuously. Traditionally, the AMR moves from one point to stop at the next point or turn which is inefficient and consumes much energy. This paper proposes the new concept of AMR trajectory path planning with curvature driven by maximizing speed control of the differential drive at each curve to move smoothly. B-splined is commonly applied to CAD and CAM machining effectively for tool path trajectory. Therefore, the B-splined curvature is studied and validated by simulation together with energy consumption. The simulation is on Matlab Simulink with numerical model. It is investigated that the B-splined trajectory is efficient in animating the AMR’s actual system. The velocity can obtain both linear and angular velocity of the AMR movements on forward and backward directions as well as the acceleration. The trajectory can be selected based on the degree of closeness and used to generate speed and velocity control for the AMR system.

Usulan Perbaikan Proses Produksi Pada CV. Kandayas Furniture dengan Pendekatan Model Simulasi Sistem

Kandayas Furniture is one of the companies engaged in manufacturing tables. The table production process goes through several stages. Based on field observations and interviews that have been conducted, problems arise from the company's production process. The problem exists in the assembly process because many products are waiting, so there is a buildup in the assembly process of the table. The buildup occurs because the assembly process to the finished material warehouse has a considerable distance difference. This resulted in an ineffective production process. Then, in Promodel Now the movement of each work station still uses human labor which results in delays in the production process. From this problem, it is obtained that the process flow changes are more structured, the material handling distance from assembly to finished goods is shorter because there are changes in the lay out that we propose and make material handling time more efficient, using handlift conveyance in each flow, adding assembly operators due to bottlenecks in assembly due to the paint drying process, using a paint oven machine for drying paint to shorten the time and reduce the accumulation of goods, and implementing K3 according to the SOP so that employees avoid work accidents.

Evaluation of exposure to volatile organic compounds (BTEX) and Polycyclic Aromatic Hydrocarbons (PAHs) in gas station workers and oxidative stress assessment in Karaj city

Gas stations are one of the sources of benzene, toluene, ethylbenzene and xylene (BTEX) and polyromantic hydrocarbons (PAHs). The present study was conducted with the aim of evaluating the level of breathing exposure of gas station workers to BTEX, PAHs and oxidative stress caused by exposure to these compounds in Karaj city. Oxidative stress and reactive oxygen species (ROS) is one of the mechanisms involved in the toxicity caused by exposure to gas vapors. In this study, all 25 gas stations in the city of Karaj were investigated. Personal sampling and analysis of BTEX and PAHs was done according to National Institute for Occupational Safety and Health (NIOSH) 1501 and 5515 methods, respectively. Finally, oxidative stress markers were investigated in 25 gas station workers and 25 control group. The results showed that the mean age and employment history of gas station workers are 39.96 ± 9.55 and 12.84 ± 6.92, respectively. Also, no significant difference was reported between gas station workers and control subjects in terms of oxidative stress parameters including the level of ROS, oxidized glutathione (GSSG) content, malondialdehyde (MDA) and reduced glutathione (GSH) content. The concentration values of personal exposure of gas station workers to BTEX and PAHs are lower than the occupational exposure limits (OEL). Although the level of oxidative stress parameters in gas station workers is higher than the control group, this difference is not statistically significant (p>0.05). It is recommended to take personal protection measures in case of chronic exposure.

ABSTRACT This study investigates the implementation of the station-rotation blended learning model in science education within rural classrooms in Turkey. The research employs a case study approach to explore the learning experiences of 5th-grade students as they engage with this model. Throughout the implementation, teacher-led instruction, online instruction, and independent work instruction stations were established, and students rotated between these stations. The participants include eight 5th-grade students, comprising five girls and three boys, aged 10-11. Data were collected through focus group interviews, open-ended questionnaires, reflective diaries, and a researcher diary including researcher observations. The students expressed positive sentiments, stating that they learned better in the teaching process, found the lessons enjoyable, acquired independent learning skills, gained different perspectives, improved their peer teaching and collaboration skills, and experienced increased interest in the subjects. However, they also reported negative experiences, such as limited classroom space, issues during station transitions, and insufficient time. Additionally, students mentioned facing the most difficulty with the independent work station, finding the online station the most entertaining, and considering the teacher-led station to provide the most information. Finally, two models for the implementation of the station-rotation model in science classes, tailored for small and large classes, are proposed.

Biochemical study of the effect of lead exposure in nonobese gasoline station workers and risk of hyperglycemia: A retrospective case-control study.

Evaluate the relationship between blood lead (Pb) levels and other biomedical markers and the risk of diabetes in gasoline station workers. The participants were separated into 2 groups: group A consisted of 26 workers from gasoline filling stations, while group B comprised 26 healthy individuals. Serum levels of malondialdehyde, IL-1β, visfatin, insulin, fasting blood sugar, and vitamin D were assessed. Mean Pb level was significantly higher in group A compared to group B (almost 2.9 times higher levels) (14.43 ± 1.01 vs 5.01 ± 1.41, µg/dL). The levels of visfatin (23.19 ± 0.96 vs 3.88 ± 0.58, ng/mL), insulin (22.14 ± 1.31 vs 11.26 ± 0.75, mU/L), fasting blood sugar (118.4 ± 26.1 vs 82.7 ± 9.2, gm/dL), malondialdehyde (6.40 ± 0.27 vs 1.62 ± 0.21, nmol/mL), and IL-1β (330.25 ± 10.34 vs 12.35 ± 1.43, pg/mL) were significantly higher in group A, meanwhile; vitamin D (11.99 ± 1.55 vs 35.41 ± 3.16, ng/mL) were significantly lower in group A. A positive association exists between blood Pb levels and increased inflammatory markers. Lead exposure increases serum insulin and fasting blood sugar, which suggests that it is diabetogenic and that increased inflammation is a possible cause.
