Analisis Kesulitan Belajar MYOB Accounting dalam Mata Pelajaran Komputer Akuntansi (Studi Kasus Pada Kelas XI Akuntansi Keuangan dan Lembaga SMK Negeri 1 Purwodadi 2021/2022)

This study aims to find out what learning difficulties are experienced by students of class XFinancial Accounting SMK Negeri 1 Purwodadi in the 2021/2022 academic year. This type of research is qualitative research with a descriptive design. The research subjects were MYOB Accounting teachers and 15 students of class XI Financial Accounting and SMK Negeri 1 Purwodadi as respondents. Data collection techniques used include interviews and observations. To ensure the validity of the data, triangulation (source and technique) was used. The data analysis technique uses data collection, data reduction, data presentation and drawing conclusions. The results showed that there were several difficulties experienced by students in learning MYOB Accounting, namely the lack of understanding in English, lack of understanding in operating computers. lack of understanding of basic accounting, computers that sometimes error, time constraints, delivery of material from teachers and students do not have devices that support MYOB learning at home. The conclusion of this study is that students experience learning difficulties due to a lack of understanding of English terms, lack of ability to operate computers where students look hesitant when holding a computer as well as when printing assignments on a print machine students look confused, there is a computer error , students only learn MYOB at school because dirumah does not have adequate devices to install the MYOB application, limited time in learning MYOB due to being cut off with On the Job Training (OJT) time, lack of student understanding of basic accounting, and teacher delivery that is too fast to make students lag behind the material that has been taught

Field oriented control driver development based on BTS7960 for physiotherapy robot implementation

In conjunction with sustainable development goal 3 (SDG 3), it is important to develop a national electrical component for physiotherapy robot development. This study aimed to develop an open-loop field-oriented control (FOC) driver utilizing BTS7960. The driver utilized three BTS7960s that produce sinewave with variable angular frequency (ω). The research then compared the open-loop FOC driver with electronics speed controller (ESC) performance to drive a brushless DC (BLDC) motor with an initial rotation per minute (RPM) of 400, 500, and 600. The main observation was RPM reduction when the BLDC motor was subjected to loads of 20, 35, 50, 65, and 80 gr. The result showed that the open-loop FOC driver performed better, especially on an 80 gr load. For an initial RPM of 600, the RPM reduced to 100 when controlled with an open-loop FOC driver, but lesser when controlled using ESC. The open-loop FOC driver produces higher torque on the BLDC motor so it could rotate with less reduction compared to ESC, which is evident. The open-loop FOC driver can be easily developed using BTS7960 with a settling time of 4 seconds. However future studies should still consider close-loop FOC drivers to achieve higher torque performance and faster transient response for physiotherapy robot applications
