Abstract

One of the causes of traffic accidents is the vehicle factor caused by the brake system that is not functioning properly. Brakes are a very important component in a vehicle, its function is to reduce the kinetic energy of the vehicle where the safety of the driver is very dependent on this component. Materials are very important role in the design of disc brakes, the main factor in the braking process is friction, and each material has its own friction coefficient. In the automotive industry there are many types of disc brake materials, so it is necessary to conduct a more indepth study on the effect of the disc brake material to determine the deformation, stress and strain that happen during the braking process. The method we used is to design a disc brake on solidworks and simulate it in ansys 19.2 software to find the structural transient values of gray cast iron, aluminum alloy, stainless steel, and titanium alloy materials. The result of this research is a data on the transient structural disc brake of the Vario 125 CBS motorcycle with the highest maximum total deformation happens in the gray cast iron material of 8.4965 mm. For the maximum value of equivalent elastic strain, the highest happens in aluminum alloy material at 0.012275 mm/mm. For the highest maximum equivalent stress value happens in stainless steel material at 1494.3 Mpa.

Abstract

The Management of Pedagogical Competence and Professional Competence Improvement for Elementary School Teachers through Education and Training (Diklat) must be continuously enhanced and intensified, and should be conducted well to achieve the Diklat goals from the planning stage to implementation and evaluation, even though there are still some weaknesses in the planning and execution of the Diklat. This is based on a preliminary study that found about 60% of elementary school teachers in Karawang Regency apparently have insufficient mastery of teaching competencies, especially in pedagogical and professional competencies. Meanwhile, among the prospective Diklat participants, 37 individuals (61.6%) claimed to have a sufficient grasp of pedagogical and professional competencies, while 23 individuals (38.3%) lacked mastery of these competencies. The Diklat planning process involves conducting a Need Assessment analysis of the training, including a strategic program analysis, a personal analysis of prospective participants and training instructors, and an analysis of tasks related to the training's content and objectives. The implementation phase begins with Diklat packages for Mathematics Adaptation, Science Adaptation, ICT Learning, and the Reading Program. Diklat activities are carried out gradually, starting with School Team Workshops (STW), Teacher Study Groups (KKG), and Teacher Coaching and Assistance Teams (KKKS). Participants, who are elementary school teachers, are trained by MI/SD supervisors and instructors from public and private higher education institutions (PTN/PTS) using inquiry, demonstration, role-playing, and problem-based learning methods. The Diklat is expected to enhance teachers' competency by achieving a high level of mastery of the training material. They should also have a good grasp of teaching competencies and be able to contribute to improving teacher performance. Despite some challenges encountered during its implementation, including: a. A small number of training instructors lacking professionalism in mastering the training material; b. The combination of teacher participants with different educational backgrounds, some having completed SPG/SLTA-equivalent education and others holding a Bachelor's degree, resulting in varying rates of material absorption and reduced motivation for learning among SPG/SLTA-equivalent graduates; c. Insufficient computer facilities for ICT lessons.

Abstract

In general, coolant is a cooling medium used to cool workpieces and cutting tools during the machining process. In PT Komatsu Undercariage Indonesia, the LNC OKUMA 0002 chip crankcase contained a lot of stagnant coolants. The factor that causes the coolant to stagnate is that the growl is wasted through the chip conveyor and the coolant is carried along with the growl to the chip. Changing the coolant fluid needs to be done in a certain phase because the use of the coolant for too long causes sand to accumulate. Excessive sand can close the cooling duct system. The quality of the coolant can deteriorate due to heat and a dirty environment. In addition, corrosion on the radiator can also result in the deposition of dirt on the coolant. When this happens, the engine overheats easily and triggers a stall. The repairs that have been carried out are examining and repairing the components of the coolant system by adding a coolant channel and a pump that functions to suck the coolant so that the coolant returns to the LNC OKUMA 0002 engine.

Abstract

Penelitian ini membahas pengaruh variasi sudut belok dan kecepatan terhadap performa sistem kemudi pada kendaraan listrik tipe Formula SAE. Sistem kemudi memiliki peran penting dalam menentukan stabilitas, akurasi, dan kenyamanan manuver kendaraan, terutama dalam lintasan sempit dan dinamis. Tiga variasi sudut belok yang dianalisis adalah 25°, 30°, dan 45°, dengan pendekatan simulasi numerik menggunakan perangkat lunak Solidworks dan validasi melalui perhitungan manual berbasis prinsip kinematika kendaraan. Parameter utama yang dianalisis meliputi radius putar minimum, maksimum, rata-rata, serta kecepatan kendaraan dalam satuan m/s pada masing-masing variasi sudut dan kecepatan awal. Hasil menunjukkan bahwa semakin besar sudut belok, maka radius putar kendaraan menurun secara signifikan, memungkinkan kendaraan bermanuver dengan lebih lincah. Selain itu, peningkatan sudut belok dan kecepatan awal menghasilkan peningkatan kecepatan aktual kendaraan, dengan nilai tertinggi mencapai 8,93 m/s pada sudut 45° dan kecepatan 25 km/jam. Temuan ini mengindikasikan bahwa sudut belok 45° merupakan konfigurasi paling optimal dalam meningkatkan kemampuan manuver dan performa kendaraan secara keseluruhan. Penelitian ini memberikan kontribusi penting dalam pengembangan desain sistem kemudi yang efisien, stabil, dan adaptif terhadap berbagai kondisi pengendaraan, serta dapat digunakan sebagai acuan dalam pengujian kendaraan listrik di lintasan sesuai standar FSAE.
