Abstract

This paper discusses DC motor rotational speed control using fuzzy logic method. The system works by utilizing ultrasonic sensors to detect distance. The detected distance affects the rotational speed of the DC motor which is controlled by the Arduino UNO microcontroller. Fuzzy logic is applied to the Arduino UNO microcontroller in which distance as the input, and the rotational speed of the DC motor in the form of Pulse Width Modulation as the output. There are several classifications of distance: very close, close, normal, far and very far. In addition, there are several classifications in the motor rotational speed response: slow, very slow, medium, fast, and very fast. The design of the fuzzy logic system is carried out in the Arduino IDE application and MATLAB using the Mamdani method at the inference stage. Fuzzy logic system is run on the Arduino UNO microcontroller in which the simulation is carried outthrough Proteus application. The test results show that the largest percentage of errors/discrepancies between the Proteus system design and the MATLAB is 1.55%. In the future, this simulation can be applied to systems such as selfdriving cars.

Abstract

The environmental uncertainty due to the COVID-19 pandemic poses severe challenges for all parts of the supply chain in the tourism industry. The focus of the Indonesian government is to improve the condition of the tourism industry, which has experienced a decline in the number of tourists due to the Covid-19 pandemic. A supply chain tourism industry framework was developed through the Support System and Facilities (SSF) variable with the aim of being able to map the actors in the tourism industry activities in an uncertain environment due to COVID-19. The method in this study uses a qualitative descriptive approach through in-depth interviews, direct observation, and literature study. The results of this study state that there are several stages in distributing services and support systems and facilities to tourists, namely through suppliers, tour operators, tour agencies, and tourists. This finding has practical implications for the government in making a policy strategy.

Abstract

CV. Istiqomah Furniture is a company engaged in manufacturing furniture located in Klaten, Central Java. The problems that are often faced by CV. Istiqomah Furniture, namely the decrease in worker productivity and the number of final products that are not following company standards. One of the departments responsible for these problems is the service department. The high intensity of work in the service department can cause a mental burden for workers. The purpose of this study is to calculate the mental workload felt byworkers, find out the dominant factors that cause this mental burden, and provide alternative improvements based on the problems faced by the company. The method used in this research is NASA-TLX (National Aeronautics and Space Administration Task Load Index). The results of this study are that the average worker has a high mental workload with a WWL value of 72.11, and the mostinfluential factors are physical and mental needs. Based on these results, the proposed improvements provide sufficient rest time, improve worker safety and comfort, increase work motivation, provide adequate facilities, conduct medical tests, and provide good nutrition.
