A cable car is a hanging car that runs by cable. Cable car carrier controlled by DC motor. The cable car can be a solution to accommodate the mobilization of agricultural commodities in areas that are difficult to access while still paying attention to safety and reliability. In this research, the speed of a cable car would be automatically controlled with Programmable Logic Control (PLC). PLC functions as a cable car operation controller by considering 3 parameters, namely: wind speed, maximum load weight, and distance (meters). The speed of the cable car is controlled by the PLC using fuzzy logic. Cable car speed is based on parameters of wind speed, load weight and distance. From the results obtained, the PLC has worked well in regulating the speed of the cable car and if any parameter exceeds the PLC limit, it can turn off the cable car.

Automatic Transfer Switch (ATS) adalah suatu rangkaian yang mampu memindahkan beban dari sumber listrik utama ke sumber listrik cadangan. Apabila kemudian PLN kembali normal selanjutnya ATS bertugas untuk mengembalikan jalurnya dengan memindahkan switch kembali ke sisi utama. Suplai daya utama dari PLN tidak selamanya berkesinambungan, suatu saat pasti terjadi pemadaman yang dapat disebabkan oleh perawatan secara berkala atau pun gangguan pada pembangkit di sistem distribusi dan sistem transmisi. Maka untuk mengatasi hal tersebut diperlukan back up daya yang berupa generator. Kendala dalam menggunakan generator ini adalah ketika suplai daya dari PLN terputus operator akan membutuhkan waktu yang lama dalam menghidupkan generator, inilah mengapa kita membutuhkan alat bantu otomatis untuk mempermudah operator yakni ATS. Alat yang dibuat ini dilengkapi dengan Programmable logic control (PLC), PLC ini merupakan sistem kontrol utama untuk alat yang akan dibuat sebagai kontrol otomatis sehingga memudahkan dalam pembuatan, instalasi, dan perawatan.Kata kunci : ATS, PLC, Generator

DC motors are included in the category of motor types that are most widely used both in industrial environments, household appliances to children's toys. The development of control technology has also made many advances from conventional control to automatic control to intelligent control. Fuzzy logic is used as a control system, because this control process is relatively easy and flexible to design without involving complex mathematical models of the system to be controlled. The purpose of this research is to study and apply the fuzzy mamdani logic method to the Arduino uno microcontroller, to control the speed of a DC motor and to control the speed of the fan. The research method used is an experimental method. Global testing is divided into three, namely sensor testing, Pulse Width Modulation (PWM) testing and Mamdani fuzzy logic control testing. The fuzzy controller output is a control command given to the DC motor. In this DC motor control system using the Mamdani method and the control system is designed using two inputs in the form of Error and Delta Error. The two inputs will be processed by the fuzzy logic controller (FLC) to get the output value in the form of a PWM signal to control the DC motor. The results of this study indicate that the fuzzy logic control system with the Arduino uno microcontroller can control the rotational speed of the DC motor as desired.
