Abstract

Technology continues to develop, especially in the world of manufacturing. Processes done manually by humans are replaced gradually by machines through automation. This paper proposes a batik drawing machine with Arduino-based computer numerical control (CNC). The intention is to reduce the production of small-sized batik products by eliminating the sketching process of the batik design on the fabric. Besides, the expertise in using canting, a pen-like tool, to apply the liquid wax on the fabric will not be required. A prototype of a batik drawing machine was designed and constructed using main components such as Arduino Mega 2560, NEMA17 HS4401 stepper motor, and RAMPS 1.4 controller board. The batik design data is to be prepared by using a graphic editor, computer-aided design (CAD), and computer-aided manufacturing (CAM) software. After several trials, the best setting for the canting temperature was found to be 112 °C with a drawing speed of 25 steps/mm and a 3 mm distance between the cloth and the tip of the canting. Three batik designs with different difficulty levels were tested for fabric printing. The fabrics were colored to obtain the final results. The batik products with a diameter of up to 450 mm can be finished satisfactorily

Abstract

Machines are valuable assets that need to be protected from damage and failure through proper maintenance measures. This paper proposes a system that automatically monitors the running time of machines and sends notifications regarding their preventive maintenance (PM) schedules. The system core consists of a programmable logic controller (PLC) and a human machine interface (HMI). The HMI is connected to an online platform via internet connection provided by a router, so that the monitoring result can be accessed via Android smartphone or laptop/PC. This IoT-based running time monitoring system (IRTMS) will be particularly helpful in implementation at an production site that consists of multiple various machines. The PM items of a machine may vary from cleaning, changing single component, to an overhaul, each with different time interval. By using the IRTMS, the user will have an overview of the PM schedules anytime and anywhere. The preparation of material, components, or tools can be known ahead of time. For simulation purpose, a prototype is constructed by using components as used in industrial real-life condition. Four output connections are provided to simulate the simultaneous monitoring of four machines. The IRTMS prototype is tested and completely successful on doing the running time monitoring, the running time reset, the PM notifications, and the remote access for monitoring and control.

Abstract

In the midst of lakes or oceans, boats used for recreational fishing that are left immobile are more vulnerable to rolling waves or wind. This study was conducted to develop a prototype of the boat's stabilization system and control scheme in order to address the stability issue with the craft. Based on the prototype concept, a small boat was constructed with a control loop that included two DC motors, a motor driver, a gyroscope MPU6050, and an Arduino Uno microcontroller. A prototype stabilizer was used to evaluate two different sets of control parameters, and in both situations the stabilizer was able to provide the boat with critical interference before bringing it back to a vertical position. PWM 1 level change rate (Pulse-Width-Modulation) yields better results than 4 level change rates (PWM), with faster stabilization achievement. (1,12 seconds versus 2,46 second). In the development of the prototype, it is necessary to test the implementation of the system on the boat to the actual size.

Abstract

The rapid development of the Industrial Revolution (IR) 4.0 and the transition towards Society 5.0 demand an increase in digital literacy and a basic understanding of technology systems starting from secondary education. The Community Service (CS) Program conducted by the Department of Electrical Engineering Universitas Presiden aims to introduce the concepts of logic gates and digital systems to students of SMA 1 Cikarang Pusat. This CS integrates theoretical explanations and simulation practice using the online platform Circuitverse. This CS was evaluated using a Likert scale (1–4) questionnaire instrument, namely Expectation (Importance) and Performance, with a total of 40 student respondents. The analysis results show that all indicators received an average performance score above 3.30, with satisfaction indices ranging from 82.50% to 90.62%, which falls into the very high category. The indicator for the use of appropriate technology received the highest score of 90.62%, indicating the relevance of the material to current technological developments. The Importance–Performance Analysis (IPA) shows that most indicators are in the 'maintain performance' quadrant, indicating alignment between participants' expectations and the activity's performance. These findings suggest that the workshop is effective in enhancing students' understanding of basic digital system concepts while also fostering interest in engineering and technology fields. The activity underscores the strategic role of universities in bridging the technology literacy gap at the secondary education level in response to the challenges of the IR4.0 and Society 5.0.
