In fact,the distribution of credit facilities for microenterprises are much less than for non-microenterprises. It is shown by the existing distribution of outstanding credit. Non-performing loan often becomes the reason to limit the distribution of credit for microenterprises. Nevertheless, the contribution of non-performing loan of microenterprises is much less than non-performing loan of non-microenterprises. The result shows that the proportion of distribution of outstanding credit and non-performing loan of microenterprises are much less than the proportion of distribution of outstanding credit and non-performing loan of non-microenterprises.

The KMLI E-Falco electric car uses a BLDC type electric motor with a power capacity of 2 kW. To find out the amount of torque of a 2 kW BLDC motor when driving with variations in speed, it can be done by manual calculations using the torque equation and doing a dynotest test. The dynotest results show that the motor torque at the speed: 1 km/h is 1 Nm, 10 km/h is 131 Nm, 13 km/h is 228 Nm, 20 km/h is 225 Nm, 30 km/h is 219 Nm, 40 km / h is 188 Nm, 50 km / hour is 145 Nm, 60 km / h is 113 Nm, and 70 km / h is 85 Nm. From the results of the dynotest, it shows that the peak torque occurs at a speed of 13 km / h at 228 Nm. Racing software installed in the controller can increase the motor torque by four times at a speed variation of 13-70 km/h based on the results of the dynotest above. Keywords: motor, BLDC, torque, speed, acceleration.

In fact,the distribution of credit facilities for microenterprises are much less than for non-microenterprises. It is shown by the existing distribution of outstanding credit. Non-performing loan often becomes the reason to limit the distribution of credit for microenterprises. Nevertheless, the contribution of non-performing loan of microenterprises is much less than non-performing loan of non-microenterprises. The result shows that the proportion of distribution of outstanding credit and non-performing loan of microenterprises are much less than the proportion of distribution of outstanding credit and non-performing loan of non-microenterprises.

The KMLI E-Falco electric car uses a BLDC type electric motor with a power capacity of 2 kW. To find out the amount of torque of a 2 kW BLDC motor when driving with variations in speed, it can be done by manual calculations using the torque equation and doing a dynotest test. The dynotest results show that the motor torque at the speed: 1 km/h is 1 Nm, 10 km/h is 131 Nm, 13 km/h is 228 Nm, 20 km/h is 225 Nm, 30 km/h is 219 Nm, 40 km / h is 188 Nm, 50 km / hour is 145 Nm, 60 km / h is 113 Nm, and 70 km / h is 85 Nm. From the results of the dynotest, it shows that the peak torque occurs at a speed of 13 km / h at 228 Nm. Racing software installed in the controller can increase the motor torque by four times at a speed variation of 13-70 km/h based on the results of the dynotest above. Keywords: motor, BLDC, torque, speed, acceleration.

College, public, and regional libraries have started to develop digital libraries. The development of digital libraries is based on the consideration of providing opportunities for greater access to collections owned by libraries and adjusting the format of library services with the characteristics of users who are familiar with information technology products. Seeing the importance of digital libraries, BPAD DIY began to develop a digital library under the name I-Jogja. I-Jogja is a digital library portal developed in the Android and iOs operating systems. I-Jogja was developed using the iLibrary software created by PT. Woolu Maya script. I–Jogja offers a new concept in digital library management, where to access public collections, people do not need to download but borrow collections from the digital library portal. This digital collection lending concept is known as e-lending. Through research, the r...

Three previous editions of Team Building have been well received by managers, team leaders, and team consultants. In fact, roughly 100,000 copies have been sold in several languages over the almost three decades since our father, William G. “Bill” Dyer, wrote the first edition, making it one of the most widely read books on the subject. Bill was the consummate social scientist, trained in sociology at the University of Wisconsin after World War II. He had grown up in a rather large family of seven children (one was his half-brother Jack Gibb, another prominent social scientist) in a rather poor section of Portland, Oregon. Bill’s father ran a small grocery store attached to their home, and it was there that Bill learned the importance of hard work, and teamwork, as he worked in the family store. From these experiences he also recognized that education was the key to his future.
