Abstract

Madura stalls, as part of informal micro-enterprises, play a vital role in meeting the needs of urban communities. However, most still operate without a structured strategic management system and performance measurement. This situation makes it difficult for business owners to monitor efficiency, understand customer satisfaction, and plan for long-term competitiveness. On the other hand, there is a research opportunity to adapt modern management methods, such as the Balanced Scorecard (BSC) and Value Engineering (VE), to suit the context of simple yet influential small businesses. This study aims to design a performance measurement system by integrating VE into the BSC framework at a Madura stall in Klampis, Surabaya. The method used is an exploratory case study with a mixed-methods approach, involving owners (n = 5), employees (n = 10), and customers (n = 30). Data were collected through interviews, observations, questionnaires, and document review. Data were then analyzed using the Function Analysis System Technique (FAST), KPI formulation, AHP weighting, and performance evaluation. The study results show that several key performance indicators exceeded targets, such as daily sales volume (226.7%), number of customers (200%), and net profit (120%). These achievements confirm that the integration of the BSC and VE can improve cost efficiency, strengthen customer orientation, and provide a clearer strategic direction for informal micro-enterprises. This study contributes by providing a contextually relevant performance measurement framework and opens up opportunities for further research on the application of the BSC and VE to other micro-enterprise units.

Abstract

The current condition, learning media in Manufacturing Process Design practicum still lacks teaching aids so that it cannot adjust its output according to industry needs. This needs to be improved to support industry-based learning. Before implementing teaching aids, the learning process was theoretical and did not involve students in real simulations, so their understanding of the manufacturing workflow was limited. This study aims to design and implement teaching aids in Manufacturing Process Design and Assembling practicums to support learning with the Learning Factory approach. The design of the teaching aids begins with observing the existing conditions, then determining the improvement plan through focus group discussions. After that, the design is carried out according to the needs of the practicum. The teaching aids made use a Programmable Logic Controller consisting of 4 stations. The use of designed teaching aids provides students with direct experience in the design and assembly process, and facilitates more interactive learning. The results of the study showed a significant increase in students' understanding of the manufacturing process, with more active involvement and an increase in the quality of assignments and practicum reports. These teaching aids have proven effective in creating a learning environment that is closer to real industrial conditions, so that they can improve students' competence in understanding manufacturing and assembly processes comprehensively.

Abstract

Improving and enhancing the performance of both service and manufacturing systems is essential for achieving customer satisfaction with the service. Research on improving and enhancing the performance of gas stations, whether using simulation methods or combinations with other methods, has been extensively conducted. However, studies that focus on improving the queue system at gas stations using simulation methods to reduce queue length and total operational costs are still limited. Previous research has proposed changes in the combination of fuel types at nozzles and the number of operators working per shift to reduce operational costs. However, these studies did not consider the resulting queue lengths. Therefore, this study will propose a design for the queue system and determine the number of operators to reduce queue length and total operational costs. First step, a simulation model of the actual queue system is created. Next step, alternative scenarios are developed for fuel type allocation at each nozzle and for determining the number of operators. Then, a simulation model of the queue system for each scenario is created. The final step is to calculate the queue length and total operational costs for the actual and proposed queue systems. There are 5 alternative scenarios to reduce the number of operators, with the best alternative being scenario 5. Scenario 5 also results in a shorter average vehicle queue length and lower total operational costs compared to the actual queue system. The average vehicle queue length decreased by 0.52 units or 31.71%. Additionally, the total operational cost decreased by Rp 714,717.74, or 23.24%.

Abstract

In the process of learning, having good memory skills is crucial for students. Several factors can affect memory, one of which is an external factor, sound. Sound distraction can disrupt concentration, speed up the pulse rate, and cause sleepiness, but on the other hand, it can also eliminate sleepiness. This research aims to analyze the effect of type and intensity of sound on college students' short-term memory abilities, sleepiness level, and heart rate, analyze the relationship between these variables, and provide suggestions for a conducive learning environment. This research was conducted in a laboratory using Task Short-Term Memory, the Stanford Sleepiness Scale, and an oximeter. The data collected will be processed using ANOVA and Pearson Correlation Tests. The results indicated that the type of sound (preferred music and crowd noise) and sound intensity (±50 dB and ±70 dB) do not affect short-term memory ability, sleepiness level, and heart rate. Furthermore, sleepiness level has a negative correlation with heart rate. Based on the findings, the optimal learning environment suggested for college students is music with a preferred intensity of ±50 dB. In contrast, the worst learning environment is a crowded environment, such as a café.

Abstract

In the modern era, consumers prioritize convenience and speed in shopping, making drive-thru services an innovative solution to meet this demand. To retain customers, Customer Satisfaction is the key to winning the competition. This study aims to examine the relationships between variables influencing Customer Satisfaction and their impact on Repurchase Intention. The research variables include Perceived Value (X1) and Service Quality (X2) as independent variables, Repurchase Intention (Y) as the dependent variable, and Customer Satisfaction (Z) as the mediating variable. Each variable will be measured by its respective indicators. This research employs a causal research design with a quantitative approach, utilizing primary data collected from 160 respondents via accidental sampling. Data analysis was performed using the SEM-PLS method. The results show that Perceived Value and Service Quality have a significant positive effect on Repurchase Intention. Perceived Value has a positive but not significant effect on Customer Satisfaction, while Service Quality has a positive effect on Customer Satisfaction. Customer Satisfaction mediates the indirect effect of Service Quality on Repurchase Intention but does not mediate the effect of Perceived Value on Repurchase Intention.

Abstract

Managerial performance varies greatly, as does leadership, with some having a significant influence and others having little to no impact. One way to improve managerial performance is by implementing heart-centered leadership. Therefore, it is necessary to study the influence of heart-centered leadership on managerial performance and related variables in palm oil companies. This research aims to analyze the influence of Heart-Centered Leadership on Self-Efficacy, Communication Effectiveness, and Managerial Performance at PT Perkebunan Nusantara III (Persero). The method used in this study is Partial Least Square (PLS) analysis, with steps including data preparation, building the model (path diagram, measurement model, and structural model), running the analysis using PLS algorithms and bootstrapping to test the significance of the paths, evaluating the measurement model by assessing reliability and validity, and evaluating the structural model to assess the strength of relationships between variables using R-square values and path coefficients, followed by result interpretation. The findings show that Heart-Centered Leadership influences Self-Efficacy and Communication Effectiveness but does not directly affect Managerial Performance. Self-Efficacy has an influence on Managerial Performance, but Communication Effectiveness does not. Heart-Centered Leadership has an indirect influence on Managerial Performance through Self-Efficacy.

Abstract

The tofu industry sector in Aceh is a strategic sector to support the community's economy. In every major production, often found waste in the form of liquid waste and solid waste. Substances contained in tofu waste contain polluted substances in the form of BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand) and TSS (Total Suspendeal Solid). Energy waste also occurs in the equipment used, as well as having an impact seen from economic and environmental aspects. This research was conducted to identify the amount of waste produced in each tofu production process and to provide alternative proposals for improvement of clean production to minimize the amount of waste produced by the PT.X, Banda Aceh. This research was conducted by collecting primary data obtained directly from the company and interviews. Data processing is carried out using mass diagrams to identify waste and the concept of good house keeping clean production, material changes, technological changes, product changes and on-reuse sites. Waste produced in the form of solid waste is 5 grams of spilled soybean and pulp as much as 168 kg, while liquid waste is 109.8 L of water, 15.4 L of scattered water, 953 L of whey and 953 L of vinegar. The results of the identification get as many as 19 problems that will be given a proposal for the implementation of clean production by providing the principle of good house keeping of technological change and site on reuse.

Abstract

This study analyzes the efficiency of diesel fuel inventory management at PT. XYZ, located in Desa Peunaga Cut Ujong, Kecamatan Meureubo, Kabupaten Aceh Barat, Aceh. The main problem faced by the company is inefficient fuel inventory management, leading to a mismatch between stock and usage, potential equipment downtime, and high inventory costs. The research objective is to evaluate PT. XYZ's current fuel inventory policy and compare it with the application of the Economic Order Quantity (EOQ) method to identify potential improvements in efficiency and cost savings. The research method used is a quantitative approach with a comparative descriptive design. Secondary data, including records of fuel purchases, usage, and ordering and holding costs for 2024, were collected from PT. XYZ's Supply Chain Management (SCM) division, supplemented by primary data from interviews. Data analysis involved calculating EOQ, determining optimal ordering frequency, safety stock, reorder point, and comparing the Total Inventory Cost (TIC) between the company's existing policy and the EOQ method. The results indicate that PT. XYZ's current fuel inventory management policy incurs significantly higher Total Inventory Costs (TIC) compared to those achievable using the EOQ method. Implementing EOQ substantially optimizes order quantity, frequency, safety stock, and reorder point, which in turn can lead to considerable cost reductions. This suggests that adopting the EOQ recommendations can improve operational efficiency and provide financial benefits for PT. XYZ.
