Machine tools in manufacturing that produce workpieces with high accuracy are needed for the world of Manufacturing Industry. Machine tools that produce workpieces (low roundness deviation) with good quality will produce prices comparable to those offered. So that requires more optimum maintenance and maintenance of the engine. Mechanical Laboratory Manufacturing Polytechnic of Bangka Belitung State has several lathes to produce workpieces in the form of student training products, machined parts and production activities with a precision size, this lathe has been used for approximately 20 years, the usage of which has been long can lead to changes in machine geometry deviations. Deviations that occur will affect the quality of the product produced. Among the lathes there are 3 units of Geminis lathes. To find out the roundness deviation that occurs after being used in the teaching and learning process and the manufacture of spare parts for 20 years and to determine the feasibility of a lathe if it is used to process workpieces with a certain size tolerance, it is necessary to do testing. The test that is done is testing the geometric of the machine on the roundness of the workpiece .. The results of the cutting process of the test object will be measured by rounding the analysis by means of a minimum circle area. The three geminis have an average deviation of 45.33 μm and the smallest average deviation of 20 μm can produce workpieces with tolerances above 41 μm.

The use of bricks in both non-structural and structural construction needs to be an increase in the product produced, either by improving the quality of materials based on SNI 15-2094-2000 which explains the red brick. The purpose of this study was to analyze the effect of the Independent Variable, namely the Comparison of heating temperatures with a processing time of 12 hours, 24 hours and 36 hours, with temperatures of 300oC, 500oC and 700oC and the percentage of sand mixture of 5%, 10% and 15%. Comparison of the three independent variables will be seen what is the Optimum value of the Impact test and how the fracture that occurs is seen with SEM. The results show the smallest impact value of 264 kj / m2, and the largest value of 164 kj / m2. the calculated F value of FModel = 33.29 obtained at a significant level of 0.01 or 1% and the p value (0.0002) gives a significant value to the existing model. Whereas the Lack of Fit that occurs is 0.000199 and does not have an effect (not significant) so that the cubic mathematical model regression equation used can be accepted. Based on the interaction data and surface response to the impact strength, the effect of heating time, heating temperature and percentage of sand is very large. The point is that if the temperature and the heating time get bigger the impact test results will be even greater
