Abstract

The calculation of raw material inventory for pentol frozen products at UD XYZ using the probabilistic P Model Back Order indicates that the application of this method effectively helps the company optimize its inventory control. The probabilistic approach provides more accurate considerations in determining order quantities, order intervals, and minimizing the risk of stock shortages. The results show that beef reaches its optimal point with orders placed every 3 days at a quantity of 278.24 kg and a total cost of Rp 9,705,474, with a service level of 75%. Chicken also achieves optimal results with an order interval of every 3 days at 109.05 kg and a total cost of Rp 1,481,784 with an 80% service level. For sago flour, optimal inventory performance is achieved with orders every 6 days totaling 152.58 kg at a cost of Rp 946,617 and a service level of 76%. Meanwhile, tapioca flour reaches its optimal point with orders every 6 days amounting to 76.02 kg, a total cost of Rp 200,186, and an 81% service level. Overall, the application of the probabilistic P Model Back Order has proven to produce an efficient and measurable inventory system that supports the smooth production process of pentol frozen products at UD XYZ.

Abstract

UKM One Maxx Mojokerto is a small and medium-sized enterprise engaged in shoe production. The production process, particularly in the stage of attaching the upper to the sole, is still carried out manually using basic tools such as hammers, nails, and pliers. This method requires relatively long processing time, high physical effort, and potentially causes ergonomic complaints for workers. This study aims to design an ergonomic press machine as a work aid to improve productivity and operator comfort. The research method includes user needs analysis, anthropometric measurements for tool dimension determination, and work time analysis using the Maynard Operation Sequence Technique (MOST). The results indicate that the ergonomic press machine design is able to reduce production time compared to manual methods, increase work efficiency, and decrease workers’ physical workload. The implementation of this work aid is expected to enhance production capacity while improving ergonomic working conditions for SMEs.

Abstract

This study was conducted to analyze the imbalance between the manufacture and use of raw materials in the plastic sheet production process at PT XYZ.. As a plastic manufacturing company with an injection molding-based production process, production planning and control (PPIC) plays a crucial role in ensuring the availability of appropriate raw materials to ensure optimal production without shortages or excess stock. Raw material usage data from January to August 2025 showed significant fluctuations and discrepancies between the amount of raw materials produced and used, necessitating an evaluation of material planning methods. This study applied several forecasting methods namely Single Exponential Smoothing and Moving Average to determine the most accurate raw material requirement prediction model. The analysis results showed that the 3-Period Moving Average was the best method with the smallest MAD value and was used as the basis for preparing the Master Production Schedule of 4,585 units per period. The Bill of Material calculation demonstrated efficient material conversion, while the estimation of raw material requirements provided a more accurate picture of procurement planning. Overall, the integration of forecasting, MPS and raw material requirement calculations supports increased production efficiency and more measurable and sustainable decision-making.

Abstract

PT XYZ is a company engaged in the manufacture of semi-finished wood products. Based on field observations, where products come in varying sizes and shapes, it is important to consider ergonomic aspects in layout design. Inefficiencies in the current warehouse layout were found, resulting in long material handling times and operational disruptions. The purpose of this study was to improve the layout of the finished goods warehouse area and facilities by redesigning the facility layout at PT XYZ to optimize the finished goods warehouse layout. This study used the Activity Relationship Chart (ARC) method and volume handling analysis. A redesign was proposed to improve space management and material flow. Data were collected through observation, interviews, data analysis, and discussion. The proposed layout minimizes material movement distance and improves accessibility and ergonomics. As a result, the original facility produced 26,480 units, while the proposed facility produced 15,772 units. There was a decrease in handling volume of 10,708 units, or 40.43%, after the layout change.

Abstract

A person's social status is determined, in part, by their lifestyle. Many people prioritize their appearance and the items they use to demonstrate their social status. This trend has also given rise to financial technology systems to facilitate shopping for goods and other necessities. Lifestyle and the use of financial technology, if not balanced with adequate financial literacy, will lead someone into poverty. This study aims to determine the influence of financial literacy, financial technology, and a hedonistic lifestyle on the financial behavior of Generation Z. The data collected were primary data obtained through questionnaires. This study was quantitative, using statistical data processing. The hypotheses were tested using SmartPLS. The results indicate that financial literacy, financial technology, and a hedonistic lifestyle have a positive influence on the financial behavior of Generation Z

Abstract

The rapid evolution of retail business models in Indonesia has driven retailers to integrate offline and online shopping channels in order to adapt to shifting consumer behaviors. Alfamart has responded to this transformation by combining its extensive physical store network with the Alfagift digital platform, thereby enhancing consumer access, convenience, and the availability of product information. This study aims to examine the influence of consumer trust in offline stores and perceived confidence in online stores on consumers’ information-seeking intention and purchase intention. A quantitative approach was applied by distributing structured questionnaires to 170 respondents who had prior experience shopping at both Alfamart and Alfagift. The data collected were analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM) to assess the structural relationships among the proposed variables. The findings indicate that consumer trust in offline stores and perceived confidence in online stores have significant effects on both information-seeking intention and purchase intention. Moreover, information-seeking intention is found to significantly mediate the relationship between trust, perceived confidence, and consumers’ eventual purchase intention.
