Some of the damage that occurs in the structure and construction of engine elements that experience dynamic loading at the time of operation is caused by fatigue (fatigue), which occurs without beginning signs so that it causes great damage and loss. Fatigue strength is the process of local changes in the structure that occur permanently in accordance with the period of time caused by conditions where stress or strain occurs which results in cracks or fractures after being subjected to repetitive loads. Surface roughness factors that affect fatigue are applied in the analysis and application of machining, which are finely grinded and rough machined. Analysis was carried out on 6063-TF aluminum alloy material which is widely used for motor vehicles. To find out the effect of the above, the fatigue strength test is carried out with a Rotary Bending Fatique Test to obtain a cycle value or fatigue age and certain neighbors so that it can make a semi-log S-N diagram with statistical calculations.

Good production results will be a benchmark for a company to compete in today's free market era. To improve good quality is determined by several factors, including: raw material factors, production processes, labor, the state of the engine or dies and the environment. Basically, the production results are not all good, because there are several factors that influence it, as noted above. To overcome this, a company sets a quality requirement because it is very useful for good and quality production results. In determining good quality, it is necessary to conduct a research on the raw material at the SPC 270 E foot step by means of the testing method that will be carried out. The testing methods carried out consist of: tensile testing, hardness testing, metallographic testing, chemical composition testing, and dye penetrant testing. From the results of the research that has been done, it can be seen that the thinning material has an average tensile strength of 307.41 N/mm2, the standard used by the company is 270 - 323 N/mm2 and is still in accordance with the tolerance value. Whereas the material with a lump has an average Vickers hardness value of 124.24 HV, the standard used by the company is 135 HV and still fits the tolerance value.

Indonesia is one of the developing countries and is actively pioneering development, especially development in the industrial sector. The industry that is quite developed at this time is the manufacturing industry which produces a finished product that can be directly used by consumers. These products are expected to have a high enough quality level so that they can compete in the market. To support this quality, one of the factors is to pay attention to the level of precision of the workpiece in this case is the level of surface roughness of the object or product produced. The surface roughness value is obtained from the tests carried out on the product which has an average surface value (Ra) and a maximum roughness value (Ry). To achieve the desired roughness value, it is necessary to make improvements in metal forming work. In the variable cutting with variations in cutting speed, it is said that the cutting speed on work with smaller diameter objects should use a high cutting speed. Feeding thickness that is too large can cause high surface roughness values and high rotation at low cutting speeds to produce a smooth surface but takes a long time. With the selection of the speed of ingestion that varies for the price of the ingestion speed of 43.52 m/minute, the surface roughness value is 6.78 m, the speed is 48.32 m/minute, the surface roughness value is 3.64 m and the ingestion speed is 59.25 m. /min the surface roughness value is 6.14 m. Meanwhile, for the infeed thickness which varies for a feed thickness of 1.2 mm, the surface roughness value is 4.06 m; a feed thickness of 2.4 mm obtained a surface roughness value of 27.82 um and a feed thickness of 3.2 mm obtained a surface roughness value of 7.02 m.

This plan aims to minimize wasted energy in the air freshener system and utilize the wasted energy to heat water. Here using a split type air conditioner system which is commonly used. The author slightly modified the air conditioning system which previously used an air conditioning condenser, here the author added a condenser with a water cooler that functions as a condenser and at the same time as a water heater. The energy used to heat the water is obtained from the heat released by the refrigerant so as to minimize the energy wasted when only using an air conditioning condenser. But the air conditioning condenser is still used in this system, because when hot water is not needed, the water in the heater does not flow and of course cannot take heat from the refrigerant. In this condition the air conditioning condenser can work to help the process of releasing heat from the refrigerant. This tool can heat water up to 43oC with a flow rate of 1 liter per 9 seconds which can be used at home, SOHO, office for bathing, washing face, washing hands, etc.
