An analysis of the uncertainty value of measuring spur gear dimensions using a profile projector has been carried out. Dimensions of spur gears measured are pitch diameter, root diameter and outside diameter. The manufacture of 3 samples of spur gears was first made with a shape milling machine based on the initial technical data that had been determined. Then measurements were made with a profile projector measuring instrument for the three measuring dimensions, the best repeated measurement average was found in the root diameter measurement for the PJ01 sample of 32.4053 mm with a standard deviation of 0.0077 mm. The uncertainty method used is statistically and applies only to a series of observations. Determination of the uncertainty value is done by performing repeated measurements five times on the same sample. This method refers to ISO GUM with type A evaluation. The uncertainty value obtained for the best measurement is 0.0034 mm with an expanded uncertainty of 0.0068 mm with a 95% confidence level.

  Fixed assets are tangible assets that are owned for use in the production or supply of goods or services, for rent to other parties, or for administrative purposes and are expected to be used for more than one period. Due to its high value, relatively long use and being the company's main tool to generate revenue, investment in fixed assets (Capital Budgeting) must be carefully calculated. In addition, depreciation or depreciation is the allocation of the cost of a fixed asset which is the effect of the decline in the value of the fixed asset. The reason why many companies apply the straight line method of depreciation (Straight Line Method) is because there are relatively stable maintenance and repair costs in each period, and the costs are not affected by productivity or are not affected by deviations. Therefore, the assets owned must continue to be managed properly so that companies and individuals can benefit from the existence of these assets, especially fixed assets. But this is not the case with KSP Mandiri Sejahtera Semarang where fixed assets have not been well managed. This results in inconsistencies and calculation errors, incomplete data, which results in inappropriate decision making and the value of the company's fixed assets has not been recorded properly and accurately. With a new structured management system where the calculation and reporting of depreciation of fixed assets using the straight-line depreciation method helps the calculation of depreciation of fixed assets owned by the company, besides that it also provides information about the detailed condition of each fixed asset owned by the company so that it helps the company manage its fixed assets , as well as helping to present accurate and accurate reports for the benefit of the company's internal financial reports and taxation.
