This study conducted the manufacture of permanent magnet composite based on NdFeB magnetic powder and polymer adhesives, the purpose of this study was to determine the effect of the composition of the mixing of raw materials on mechanical properties and magnetic properties. Neodymium Iron Boron (NdFeB) composite was made by mixing of NdFeB magnetic powder and binder of silicon rubber (SR) in form liquid. The percentage of silicon rubber was varried of 5 %, 10%, 20 % and 30% by volume. Both raw materials were mixed until homogeneous and poured into the mold and allowed to dry at room temperature.The formed samples were characterized which includes the measurement of tensile strength and magnetic properties . The characterization results show that the sample with 20 % and 30 % SR has good flexibilty and other samples are rigid or not flexible. The variation in the composition of silicon rubber has a significant effect on mechanical properties and magnetic properties, especially remanence. The characteristic of flexible rubber magnet with a composition of 20% and 30% silicon rubber is that it has a tensile strength of 9.31 - 11.46 N / mm2 with an elongation of 17.55-26.74% and a hardness of 38-42 HA. While the magnetic properties achieved are magnetic field strength = 430-500 Gauss, remanence = 30-35 emu / g and coercivity of 2000 Oe

This study aims to examine in depth the dynamics of the professional identity of manufacturing sector employees in the face of an increasingly intensive wave of automation. Automation based on robotic technology and artificial intelligence has fundamentally changed the structure of work on the production floor, raising fundamental questions about how workers build, maintain, and change their professional identities in the midst of changes they cannot fully control. This study uses a Narrative Analysis approach that allows researchers to explore the construction of identity through the stories told by the participants themselves about their work life journeys. Data collection was conducted through in-depth narrative interviews with twelve employees working in the automotive and electronics manufacturing sector in the Central Java region who have experienced an automation transition in their workplaces for at least the past two years. Narrative analysis results in three main identity configurations, namely: identities that have collapsed and have not been reconstructed, identities that are in active negotiation, and identities that have been positively transformed. The findings of this study make an important contribution to the understanding of the psycho-social dimensions of technological disruption on the industrial workforce, as well as provide concrete implications for the design of worker empowerment and mentoring programs in the era of automation. Theoretically, this study enriches the conceptual framework of professional identity by including techno-social variables as determinants of identity dynamics that previously received less attention in the literature of vocational psychology and contemporary human resource management.

Laundry businesses require fast, accurate, and structured clothing weight recording to support operational efficiency and billing to customers. This study designed and built a prototype of a digital scale based on a load cell sensor integrated with the Internet of Things (IoT) to automatically record weighing data into a Google Sheets spreadsheet application. The hardware used includes a load cell, an HX711 module as an amplifier and ADC converter, an ESP32 microcontroller, and a 16x2 I2C LCD as an information display, while the software utilizes Google Apps Script as a middleware service for real-time data storage. The system is also equipped with a customer name input feature via Serial Monitor so that every weighing data stored in Google Sheets is accompanied by the customer's identity, facilitating the process of searching transaction history and creating business reports. The research method used is the Prototype method, including hardware and software design, sensor calibration, and system functionality testing using Black Box Testing. The test results show that all system components work according to the design with a high level of accuracy compared to standard scales, as well as the successful automatic sending of weighing data (weight, customer name, time, and date) to Google Sheets. Thus, this prototype effectively integrates automatic weight measurement and digital record-keeping, providing a practical solution for improving data management and operational efficiency in laundry businesses.
