ANALYSIS OF PHYSICAL AND MENTAL WORKLOAD OF WORKERS WITH CARDIOVASCULAR LOAD (CVL) AND BOURDON WIERSMA AT PT XYZ
Get PDFPT XYZ is a manufacturing company that produces fabricated components and machines for various heavy construction industries, but the well-known product is train components. PT XYZ has agreed to export train components to many countries so that PT XYZ has a large production target. Workers must work on requests for goods according to a predetermined date, which can cause fatigue. Based on these problems, this research was conducted to determine the value of the physical and mental workload of shift 1 and shift 2 PT XYZ workers and provide suggestions for improvement. Cardiovascular Load (CVL) and Bourdon Wiersma methods are used to identify the worker's workload. Based on the research results, it is known that the workload of shift 2 workers is heavier than shift 1 workers. This problem can be influenced by working hours at night which are less optimal for work. Improvements suggested to overcome this include increasing rest time, setting up a shift system or rolling shifts, and improving the workplace

META ANALYSIS THE EMISION OF GREEN PORT CITY : A LITERATURE REVIEW
Get PDFABSTRAK Air emission not only from waste or gas from chimney of factory or ships in port, but also from leaking gas of freon/chloro in air that can damaging the ozone. Our current understanding of the sources and increase in emissions of leaked refrigerant gases derives from two data sources: ground-based and airborne point measurements, or from reports of the quantity of products manufactured and purchased. Thus, port-related air pollutant emissions and their environmental impacts are not systematically reported. The solution to the environmental impacts of refrigerant gases would therefore pass by a gas which contains no chlorine no fluorine and does not reject any CO2 emissions in the atmosphere, in brief a green gas. The method used is expected to be able to map the center of the pollutant source
