Abstract

Induction motors have a problem that is very detrimental to the system, namely their high starting current when turned on directly. Efforts to reduce the large initial currents required a soft starting method. Soft Starting aims to get a low starting current and a smoother motor rotation. The Soft Starting method will regulate the voltage and current into the induction motor by providing a triggering angle on the TRIAC which is regulated by the Arduino platform by applying the Fuzzy Logic control system. This Fuzzy Logic method uses one input "time" and one "dimmer" output. The results of the design of a soft starting on a single phase induction motor, which can flow the voltage and current gradually, so that it can overcome the problem of a current surge of 1.58A to 0.065A at the initial starting of the induction motor, and produce controlled motor rotation with 7 seconds to achieve, the speed of boarding at Soft Starting is set to 10 to 15 seconds. The use of Fuzzy Logic control can accelerate the Soft Starting process, so that the voltage and current can reach their nominal value 1 to 2 seconds faster than without using Fuzzy Logic control.

Abstract

The aim of this research is to determine the role of understanding Islamic religious education for students who have difficulty reading and writing the Koran at SMP Negeri IV Koto. The research method used is a qualitative approach. By collecting data through observation, interviews and documentation. Interviews were conducted with Islamic religious education teachers and other teachers involved in the process of helping students overcome their difficulties in reading and writing the Koran. This research shows that Islamic religious education plays an important role in helping students overcome difficulties in reading and writing the Koran. Elements such as a structured curriculum, interactive learning, and quality teacher support are very helpful in improving students' ability to master reading and writing the Koran. These results provide a better picture of the importance of Islamic religious education in schools and can serve as a guide to further improve Al-Quran education at SMP Negeri IV Koto School.
