Abstract

The effectiveness of communication is a crucial component in healthcare services, significantly contributing to patient satisfaction. In conventional contrast examination procedures, effective communication is essential for conveying information about the methods, benefits, risks, and preparation required for the examination. A survey conducted through interviews with 30 patients and their families at the Radiology Department of RS XYZ revealed that 23 respondents expressed dissatisfaction with the communication provided by radiology staff. They reported difficulties in understanding instructions and explanations, noted that explanations were poorly structured, some components were omitted prior to the examination, and the language used was often difficult to comprehend. This study aims to evaluate the effectiveness of radiographer communication in relation to patient satisfaction during conventional contrast examinations at RS XYZ. Employing a quantitative descriptive design with a survey method, data were collected via questionnaires distributed to 30 respondents undergoing conventional contrast examinations or their family members. The data were analyzed using the Percentage Index formula to measure satisfaction levels. The study was conducted between May and June 2025. Key factors assessed included respect, empathy, listening ability, clarity, and humility. The results showed that respect scored 68% (categorized as fairly satisfied), empathy 81% (satisfied), listening ability 88% (satisfied), clarity 85% (satisfied), and humility 75% (satisfied). The lowest score was for respect, while the highest was for listening ability. Overall, the effectiveness of radiographer communication in relation to patient satisfaction during conventional contrast examinations at RS XYZ reached 61%, categorized as satisfied.

Abstract

Polyester is a type of polymer commonly used in the production of bottle packaging and textile products. However, polyester takes hundreds of years to decompose naturally, making polyester waste management a critical issue. One of the emerging solutions is the production of recycled polyester. In Indonesia, the utilization of recycled polyester has seen significant growth, particularly in the textile and fashion industries. Several studies have shown that recycled polyester exhibits the same tensile strength and tear resistance as virgin polyester, but with higher stiffness, making it more suitable for geotextile applications. For example, polyester-based plastics are often used as protection in road casting. This study aims to develop nonwoven geotextile using a blend of recycled polyester and low melt polyester fibers with a basis weight of 150 g/m2. Test results indicate that the geotextile fabric has a tensile strength of 240 N, a tear strength of 109.06 N, and a concrete compressive strength of 18.91 MPa.

Abstract

Toko Sembako Mulia has adopted a web-based system to track the movement of inventory, including incoming and outgoing goods. Despite this, reports on sales, purchases, and stock-taking are still recorded manually, which increases the risk of data inconsistencies—especially when managing expired items. To overcome this challenge, an inventory management system was developed using the First Expired First Out (FEFO) strategy, the Rapid Application Development (RAD) method, and design modeling with Unified Modeling Language (UML). The system was implemented using the CodeIgniter framework, PHP as the programming language, and MySQL for database management. The resulting system provides features for managing stock reports, purchase and sales transactions, as well as employee and supplier information

Abstract

This study aims to assess the implementation of smart city innovations in West Bandung Regency in 2024, utilizing a fuzzy logic-based approach. Unlike previous research, which relied on the Unified Theory of Acceptance and Use of Technology (UTAUT) model, this study employs fuzzy logic techniques to evaluate user satisfaction with 37 prioritized innovative city applications. Fuzzy logic is selected for its capability to process qualitative and subjective data, enabling a more adaptive assessment of user perceptions. Data were gathered through structured questionnaires and in-depth interviews with public service employees, who are the primary users of these digital platforms. Evaluation dimensions—including ease of use, perceived benefits, social influence, and facility availability—were translated into fuzzy sets and analyzed through a Mamdani fuzzy inference system to derive comprehensive satisfaction scores. The results reveal that the “Smart Branding: Visit KBB” and “BA QRIS” applications achieved the highest satisfaction levels, particularly in terms of usability and infrastructure support. The study offers fuzzy logic-based recommendations to enhance the effectiveness, acceptance, and strategic development of smart city innovations. It also proposes an alternative, more responsive evaluation method for policy-making in the context of digital governance.

Abstract

This study aims to analyze the effectiveness of the AfterTreatment machine maintenance at PT XYZ using the Overall Equipment Effectiveness (OEE) and Six Big Losses methods. The AfterTreatment machine is a crucial part of the rayon fiber production process but has been experiencing a high level of downtime. The OEE method is used to measure machine effectiveness based on three key components: availability, performance efficiency, and quality. Data was collected from machine operations between September 2024 and February 2025. The results show that the average OEE value is 75.99%, which is below the world-class standard of 85%. The primary causes of low OEE are losses due to reduced speed, equipment failure, and idling & minor stoppages. By identifying the loss causes through the Six Big Losses and Fishbone Diagram methods, this research proposes improvements including preventive maintenance planning and enhanced operator training. The study concludes that machine effectiveness can be improved by minimizing major losses and optimizing maintenance strategies.

Abstract

Workload is a critical factor influencing employee performance and well-being, particularly in fast-paced work environments such as fast-food restaurants. Employee complaints and differing perceptions regarding the most demanding aspects of the job indicate a potential workload imbalance. This study aims to analyze employee workload levels, identify the most influential NASA-TLX dimensions, and explore factors contributing to high workload at Ayam Geprek Sambel Cenghar Restaurant. The research method used the NASA-TLX (Task Load Index), which measures workload based on six dimensions: mental demands, physical demands, temporal demands, performance, effort, and frustration levels. Data were obtained from 21 respondents from four operational departments: cashiers, kitchen staff, waitstaff, and chili sauce mashers (grinding). The results showed that 48% of employees were in the medium workload category, 38% in the high category, and the remainder in the low category. The dimensions with the highest scores and contributing the most to the overall workload were physical demands and effort, each contributing 18%. Based on respondents' responses, it was found that long work hours (12 hours) were the main factor increasing workload. Therefore, an evaluation of work hours, including the implementation of a rotating work system (shift), was recommended to reduce fatigue and improve operational efficiency.

Abstract

Unpredictable weather often complicates the process of drying clothes, especially when rain suddenly falls. This becomes a challenge for both households and laundry businesses. This research aims to design an automatic clothes drying system based on the Internet of Things (IoT), utilizing a rain sensor and a light sensor to detect weather conditions in real-time and automatically adjust the position of the drying rack. The research uses the prototype method, which includes rapid design, device construction, and system testing. The device is controlled by a NodeMCU ESP8266 and connected to the Blynk application for remote monitoring. A BYJ-48 stepper motor moves the drying rack based on input from the rain sensor and LDR (Light Dependent Resistor). Test results show that the system works well and responds quickly to weather changes. The drying rack automatically retracts during rain or low light conditions and extends when the weather is clear. This system offers convenience, efficiency, and a practical solution for everyday clothes drying activities
