Abstract

ABSTRAK  Sistem Electronic Fuel Injection (EFI) dan ECU (elektronic control unit) pada mobil berfungsi mengatur jumlah bahan bakar yang digunakan, system pengapian dan beberapa perangkat lainnya. Penggunaan sistem ECU pada kendaraan bermotor khususnya mobil mampu meningkatkan kinerja mobil itu sendiri. Perangkat ECU merupakan salah bentuk perkembangan teknologi dibidang otomotif. Namun perkembangan teknologi tersebut harus diimbangi dengan pemahaman dari pengguna maupun mekanik mobil sehingga apabila terjadi kerusakan pada kendaraan khususunya mobil dapat terdeteksi dan dilakukan perbaikan. Kerusakan ECU dan perangkat atau komponen lain pada sistem injeksi dapat dilakukan pemeriksaan melalui proses scanner dengan bantuan perangkat komputer atau scanner. Yang menjadi kendala saat ini yaitu belum semua mekanik atau bengkel mampu menggunakan alat scanner tersebut untuk pemeriksaan kendaraan khususnya mobil. Hal tersebut terjadi karena kurangnya pengetahuan dan wawasan khususnya tentang proses scanner mesin mobil. Berdasarkan pertimbangan tentang kurangnya pengetahuan dan wawasan mengenai proses scanner untuk mesin mobil maka perlu dilakukan pelatihan tentang cara penggunaan dan perawatan alat scanner kepada para tenaga pendidik (guru) khususnya SMK otomotif. Dengan adanya pelatihan diharapkan dapat meningkatkan pengetahuan dan wawasan dari tenaga pendidik (guru) yang nantinya akan diajarkan kepada siswa/siswi sehingga dapat meningkatkan kuailtas lulusan. Pelatihan dilakukan dengan memberikan materi, penjelasan serta pelatihan yang diikuti oleh mitra (guru-guru SMK). Dengan adanya pelatihan maka dapat meningkatkan pengetahuan dan keterampilan mitra dalam perawatan, pemeriksaan dan perbaikan sistem injeksi pada mesin mobil menggunakanperalatan scanner. Kata Kunci : Pelatihan, scanner, injeksi, Guru SMK. ABSTRACT The Electronic Fuel Injection (EFI) system and the ECU (electronic control unit) on the car function to regulate the amount of fuel used, the ignition system and several other devices. The use of the ECU system in motor vehicles, especially cars, can improve the performance of the car itself. The ECU device is a form of technological development in the automotive field. However, these technological developments must be balanced with understanding from users and car mechanics so that if there is damage to the vehicle, especially the car, it can be detected and repaired. Damage to the ECU and other devices or components in the injection system can be checked through a scanner process with the help of a computer or scanner. The problem now is that not all mechanics or workshops are able to use the scanner to inspect vehicles, especially cars. This happens because of a lack of knowledge and insight, especially about the process of car engine scanners. Based on considerations about the lack of knowledge and insight about the scanner process for car engines, it is necessary to conduct training on how to use and maintain scanner tools for educators (teachers), especially automotive vocational schools. With the training, it is expected to increase the knowledge and insight of educators (teachers) which will later be taught to students so that they can improve the quality of graduates. The training is carried out by providing materials, explanations and training which is attended by partners (vocational teachers). With the training, it can increase the knowledge and skills of partners in the maintenance, inspection and repair of injection systems on car engines using scanner equipment.Keywords: Training, scanner, injection, SMK teachers.

Abstract

This study evaluates the potential of wet cassava stems, dry cassava stems, and dry cassava stem powder as biomass fuels for co-firing in power plants. The analysis includes proximate testing, calorific value, and ultimate analysis to determine the quality and combustion efficiency of each material. Proximate test results show that dry cassava stems have lower moisture content and higher ash content compared to wet cassava stems, which can affect residue and slagging in power plant equipment. The high volatile matter content and significant increase in fixed carbon from wet to dry conditions indicate a greater extractable energy potential. The gross calorific value shows a significant increase from 2676.11 kcal/kg (AR) to 4929.44 kcal/kg (DAF) for wet cassava stems, and from 3910.64 kcal/kg (AR) to 5046.48 kcal/kg (DAF) for dry cassava stems. Dry cassava stem powder shows a very high calorific value, reaching 4272 kcal/kg (DB). The best ultimate analysis results for cassava stem powder are carbon (C) 48.44%, hydrogen (H) 6.61%, oxygen (O) 43%, sulfur (S) 0.15%, and nitrogen (N) 1.80%.

Abstract

Used brake shoes are a component of a two-wheeled vehicle that has a type of aluminum material. Therefore, we can do remelting aluminum from brake shoes that can no longer be used for advanced application use and utilization of brake shoe waste which still has a sale value. This study aims to determine the best value or the one that approximates the fatigue limit endurance value of each loading variation given to the specimen and to determine the characteristics of the fracture surface from the differences in given loading. The research method used for fatigue testing is by using a literature study and direct observation or observation. Before doing the fatigue testing, first, do the tensile test to get the yield strength value where this value is used for the loading that will be given to the fatigue test, the loading variations are given for the fatigue test are 40%, 50%, and 60 % of the yield strength value. From the results of fatigue testing at a load of 60% with the stress of 100.2 MPa and a given load of 3.81 kg, it can be seen that the value of material fracture at 27,421 cycles and in the timeframe 00:18:16. Then at 50% loading with the stress of 83.5 MPa and a given load of 3.18 g, it can be seen that the fracture value of the material in the 51,659 cycles in the fracture period is 00:34:35. Then in the next test with a load of 40% and given the stress of 66.8 MPa and a load of 2.5 kg, it is known that the fracture value of the material in the 106,930 cycles in the fracture period reaches 01:11:17. From the test data, it can be concluded that the ratio between cycle and time with voltage is inversely proportional, that is, the smaller the voltage the greater the cycle and time obtained, and vice versa, the greater the voltage, the smaller the cycle and time will be obtained. Keywords: Used brake shoes, Aluminum, Remelting, load variation, fatigue test.
