Abstract

ABSTRAK Semua kegiatan mulai terganggu akibat pandemi Covid-19 yang sedang berlangsung, terutama di sektor pendidikan. Pelayanan masyarakat ini kemudian diharapkan dapat menganalisis tingkat pemahaman guru terhadap beberapa metode pembelajaran yang diterapkan berdasarkan perspektif guru SMKN 12 JAKARTA sebelum dan setelah berbagi pengetahuan. Dalam kegiatan ini, metode yang digunakan adalah kualitatif, dengan implementasi teknis adalah survei SMKN 12 JAKARTA yang dihadiri oleh 40 guru. Kegiatan dimulai dengan distribusi pre-test kepada para guru, dilanjutkan dengan berbagi pengetahuan dan diskusi tanyajawab. Kemudian diakhiri dengan distribusi kuesioner (post-test). Data dalam kuesioner kemudian diproses menggunakan uji skala Likert, yang mendapatkan hasil yang berbeda untuk setiap pertanyaan. Dengan demikian, kesimpulan yang diperoleh adalah para guru sudah memahami dasar-dasar metode pembelajaran, sinkronus dan asinkronus. Selanjutnya, di masa depan, mereka dapat mampu menjalankan metode pembelajaran secara mandiri. Kata Kunci: Asinkronus, Kuesioner, Metode Pembelajaran, Pasca Covid-19, Sinkronus ABSTRACT All activities began to be disrupted due to the ongoing Covid-19 pandemic, especially in the education sector. This community service is later expected to be able to analyze the level of teacher understanding of several learning methods that are applied based on the perspective of the SMKN 12 JAKARTA teacher before and after sharing knowledge. In this activity, the method used was qualitative, with the technical implementation being the SMKN 12 JAKARTA survey which 40 teachers attended. The activity began with distributing pre-tests to the teachers, followed by knowledge sharing and question-and-answer discussions, and then ended with distributing questionnaires (post-test). The data in the questionnaire was then processed using the Likert scale test, in which different results were found for each question. Thus the conclusions obtained by the teachers already understand the basics of learning methods, synchronous and asynchronous. Furthermore, it will be able to run the learning method independently in the future. Keywords: Asynchronous, Learning Method, Post Covid-19, Questionnaire, Synchronous

Abstract

An electric motor is an electromagnetic machine commonly utilized across various industries and automotive products. One prevalent type of electric motor employed in electric vehicles is the Permanent Magnet Brushless DC Motor (PM-BLDC), a brushless motor employing permanent magnets. However, despite its efficiency, permanent magnet motors often experience vibrations that can disrupt their performance. This research aims to optimize the existing BLDC motor design, with a specific focus on reducing the existing cogging torque. Initially, the existing design exhibited a cogging torque level of 0.21482 Nm. The optimization process involved modifications to several key design parameters, such as air gap, magnet thickness, magnet type, and slot opening width. In previous research, only comparisons were made between stator slot designs, which proved to be less effective as significant differences were not evident in the results of the comparative analysis of BLDC motor designs. So, in this research, the Taguchi method was utilized for the optimization process due to several advantages it offers. Through an analysis of means and variance, the optimization process successfully achieved a significant reduction in cogging torque by 0.099744 and an increase in efficiency by 0.6%. The results of the optimized permanent magnet BLDC design indicated a cogging torque value of 0.115072 Nm and an efficiency of 86.64% at an operational motor speed of 1500 rpm. This research provides a substantial contribution to the development of more efficient electric motors suitable for various applications.
