Abstract

The labor-intensive apparel manufacturing sector is continually focused on meeting output goals, necessitating continuous improvements in production efficiency. Achieving targets at the lowest feasible cost is crucial for production management efficiency, especially in clothing production. The sewing component plays a vital role in enhancing the usefulness of clothing through a series of steps to produce ready-made garments. To optimize this process, we developed a model using an artificial intelligence (AI)-based method, specifically Artificial Neural Networks (ANNs), to enhance sewing production efficiency. The model focused on optimizing parameters that significantly influenced efficiency. Our results demonstrate that the ANNs model, with 1000 iterations, successfully replicates empirical data with an R-squared value of 0.98. The research introduces the novel use of an ANNs model with a five-node configuration and 1000 iterations, proving effective in optimizing sewing process parameters. This AI-based approach is a powerful tool for improving production efficiency in the textile industry, making significant theoretical and practical contributions. The findings offer substantial practical implications for practitioners in the textile industry and provide a robust framework for optimizing sewing production process parameters to achieve higher efficiency.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) in the angkringan-based coffee shop sector have significant economic potential; however, many of them still face challenges in production decision-making due to limited resources and the lack of data-driven planning. This study aims to optimize the beverage production mix at Coffee Suganda, an MSME coffee shop located in Majalengka Regency, which produces 25 product variants, with three main products: palm sugar milk coffee, creamy milk coffee, and chocolate. The research applies Linear Programming (LP) to maximize profit under constraints related to raw materials, production time and is further strengthened by sensitivity analysis to examine the robustness of the optimal solution under parameter changes. Research data were collected through field observations, interviews with the business owner, and records of production and sales activities. The results indicate that the Linear Programming approach provides a more optimal production combination compared to the existing conditions and improves resource utilization efficiency. The sensitivity analysis reveals that changes in raw material availability and selling prices significantly affect the optimal solution, highlighting the importance of adaptive production planning. This study contributes practical insights for angkringan-based coffee shop MSMEs in developing data-driven and adaptive production strategies, as well as academic contributions to the literature on MSME production optimization

Abstract

The Global Positioning System (GPS) relies on highly precise atomic clocks in satellites and ground stations to determine global time and position accurately. Relativistic effects, including gravitational fields and satellite orbital motion, induce frequency shifts in these clocks, necessitating corrections for accurate navigation. This study developed a novel approach to integrate general coordinates into GPS, emphasizing implementation simplicity. We investigated the application of special relativity to calculate time and frequency shifts in GPS satellites. Our analysis estimated a daily relativistic correction of approximately 21.6 microseconds, with a positional imprecision of 6.48 km per day if uncorrected. By employing a general time-space coordinate system, we calculated position-4 and velocity-4 vectors, accounting for special relativistic effects on GPS time and frequency. The proposed method simplifies relativistic corrections while enhancing their conceptual clarity. Results demonstrate improved precision and efficiency in GPS positioning through the integration of general coordinates with a streamlined approach. This research offers valuable insights for international engineering communities, scholars, and practitioners, advancing the understanding of relativity’s impact on GPS satellite operations.

Abstract

Product damage is a common problem in storage and distribution processes, particularly due to impacts, temperature fluctuations, and uncontrolled humidity. Limitations of manual inspection systems often result in inefficient and non–real-time damage detection. This study aims to design and develop an Internet of Things (IoT) system based on Android for automated and integrated product damage inspection. The proposed system utilizes sensors to detect physical parameters that may indicate potential damage, such as vibration and environmental conditions. Sensor data are transmitted wirelessly to a server and presented through an Android application, enabling real-time monitoring of product conditions. The research methodology includes hardware design, software development, and functional system testing. The experimental results demonstrate that the system is capable of detecting and displaying indications of product damage with good reliability and fast response time. Therefore, the developed system is expected to improve monitoring efficiency, reduce the risk of product damage, and support more accurate decision-making.

Abstract

Reactive dyeing processes generally exhibit a relatively low fixation efficiency, ranging from 50% to 70%, which results in approximately 35% to 35% of the dye being discharged into the dyeing wastewater. In this study, cotton fabric was treated with a cationizing agent, CHPTAC, at a concentration of 5%, combined with different NaOH concentrations of 15%, 25%, and 35% relative to CHPTAC, using the exhaust method. The dyeing process was carried out using color Red Type A(vinyl sulfone type) and color Red Type B (monochlorotriazine type) reactive dyes. The results indicated that the cationized cotton fabric exhibited higher dye uptake compared to the untreated fabric. This improvement was confirmed by FTIR analysis, which showed the formation of N–H functional groups within the wavenumber range of 1580 cm⁻¹ to 3490 cm⁻¹. Furthermore, the color strength (K/S value) for vinyl sulfone dyed fabric increased from 1,65 for non-cationized samples to 3,31 for samples treated with 5% CHPTAC and 35% NaOH. Similarly, in monochlorotriazine dyeing, the K/S value increased from 2,04 for untreated fabric to 4,07 after the cationization process. The rubbing fastness test demonstrated satisfactory results, with dry rubbing values in the range of 4–5 and wet rubbing values between 3–4 and 4–5 for both vinyl sulfone and monochlorotriazine reactive dyes applied to 100% cotton fabric
