<![CDATA[The car accident while passing on the railroad tracks is not new anymore. Several assumptions emerged about the cause of the breakdown of the car. Some say it's because of the magnetic field that arises from the friction between railroad iron and railroad wheels. Various internet sites have discussed the problem of car accidents that often occur at train crossings, but do not include the cause of the accident. Logically, it is true that the friction between two metals will cause something that according to physics is called thermal energy in the form of heat. The heat generated by the friction of the railroad tracks and wheels is certainly not the cause of these accidents. In several previous studies, it was stated that the friction between the wheels and railroad tracks causes changes in the earth's magnetic field. The change in the earth's magnetic field is not yet known whether it affects the performance of a car engine. This research will look for the effect of changes in the earth's magnetic field on the performance of car engines. The engine performance under study is to compare car engine speed between car engine speed data due to changes in the earth's magnetic field with car engine speed data without the influence of changes in the earth's field using the t test method for two paired samples. The results of the data test show that changes in the earth's magnetic field do not affect the performance of a car engine speed.]]>

<![CDATA[Carburizing is a process of adding carbon content in steel by using solid media. This study aims to determine the effectiveness of the carburizing process on the hardness and depth of carbon diffusion on ST 42 steel with a variety of donor media. Meanwhile, the donor media used were teak wood charcoal, coconut shell charcoal, and graphite. The results of this study are the highest level of hardness in coconut shell charcoal, namely 815.39 HV, teak charcoal 715.5 HV, and the lowest hardness is graphite at 343.975 HV. While the highest average carburizing depth was coconut shell charcoal of 0.0133 µ, teak charcoal at 0.0085 µ, and graphite by 0.00416 µ. This shows that there are differences in the hardness value and the depth of carbon diffusion in the three types of donor media used in the carburizing process, so it can be concluded that the type of donor media can also affect the effectiveness of the carburizing process itself.]]>

<![CDATA[Tofu has the best quality vegetable protein because it has the most complete amino acid composition and is believed to have a relatively high digestibility of 85 - 98%. Basically, making tofu uses acidic / coagulation using vinegar, but different from tofu nigari, the coagulation process uses seawater rice extract. This material was chosen because in the process it does not produce waste and also does not smell so it is environmentally friendly. The background of making this tool is to provide learning as well as knowledge about tofu nigarin and to make prototypes so that it is easier to digest knowledge and also this tool uses a semi-automatic process, which usually makes tofu still using manual technology. For the method itself, it uses the fuzzy method, which is comparing several results to find out the right size in the manufacturing process. With this tool, it is hoped that the public will know what tofu nigarin is and can also use this tool to start their own business at home because by using this tool making tofu becomes easy.]]>
