In this research, the process of nitridation was carried out using the variation of temperature of 4500C, 5000C, and 5500C, and the variation of endurance time of 1 hour, then 3 hours, and 5 hours. The experiment results indicated that the highest hardness value of the steel ST 40 at the temperature of 5500C were consecutively for the endurance time of 1 hour, 3 hours, and 5 hours were 115,46 HB, 116,30 HB, and 116,51 HB. The increase in the surface hardness of the specimen is affected by the increase in temperature and holding time. Meanwhile, the results of the smallest wearing out of the steel ST 40 at temperature of 5500C with the endurance time 5 hours were consecutively at the wearing out time of 60 minutes, 90 minutes, and 120 minutes were 0,38 mm3/ minute, 0,44 mm3/minute, and 0,57 mm3/minute. The value of the wearing out on the specimen is affected by temperatue and holding time during nitriding. As for the results of the obsevation using the microscope at the micro structure of stell St 40 after undergoing nitiridation, showed an increase of number of fasa perlite at the specimen surface, the higher the heating temperature the more the fasa perlits formed, this is directly roportional with the hardness of the specimen surface.The fasa perlite formed has better hardness than of fasa ferrite.","PeriodicalId":315673,"journal":{"name":"Jurnal Teknik Mesin Sinergi","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122340468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extrusion machine made with the principle of horizontal shape and use screw conveyor as a material drive in the extrusion process. Extrusion Machine uses HDPE pellets as a test material to print filaments with a attached specification of 31.81 rpm of speed and 915 watt of element band heater power. The process of designing an extrusion machine with the screw conveyor was using standard flight or standard blade, on the grounds that the screw or thread only serves to move the material to the end of the nozzle. The screw conveyor size is 500 mm long, screw diameter is 50 mm and the distance between pitches is 25 mm followed by the dimensions of the machine is 800 x 400 x 600 mm. The test results were conducted using HDPE polyethylene pellet material with variable temperature variations consisting of 5 types of temperature, namely, 120 ° C, 110 ° C, 110 ° C, 95 ° C and 90 ° C, form the five variables above we conducted trials on each temperature. Then we got it and we concluded that the experiment using the temperature variable of 100 ° C has the most optimum output results, where the temperature of 120 ° C and 110 ° C has a liquid output result then the temperature of 90 ° C and 95 ° C has a condition where the material dries too quickly and make the nozzle clogged.","PeriodicalId":315673,"journal":{"name":"Jurnal Teknik Mesin Sinergi","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130008396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using functional suspension systems to maximize performance from vehicles. The specific function of suspension that consists of absorbing oscillation and surprise vibrations, supporting weights, maintaining geometric wheels, adding traction to the wheel, and carrying on the braking style. The BLDC motor is one of the types of synchronous motors where the magnetic field produced by the stator and the magnetic field produced by the rotor spins at the same frequency. In writing this final assignment was used by the BLDC motor in order to control the velocity of the propulsion system on a conveyor test device to move the belt conveyor. The motor BLDC is controlled by a high power brushledd controlled which has an average voltage of 48 [v], an average of 35 [a], and an average power of 1000 [w]. The power supply is supplied from a power supply capable of producing 50 [v] tension and a current of 30 [a]. The suspension test came with a 16x2 LCD to show a junction for the shock junction of the springs, and was equipped with logger data to store the junction when the current charge used a 1 - centimeter roadblock against the springs. The junction mostly comes in a suspension with a pressure of 1-3 [bar] which is 6.4 [mm]. Based on the research and discussions it may be concluded that suspension devices could move the wheels of vehicles with additional loads and fixed speed and could identify the junction with the body of vehicles using the logger data.","PeriodicalId":315673,"journal":{"name":"Jurnal Teknik Mesin Sinergi","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114727599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
