This study aims to analyze the implementation of efficiency, effectiveness, and consistency in the Standard Operating Procedure for goods procurement in the purchasing department of The Oberoi Beach Resort, Bali. This research employed a descriptive qualitative approach, with data collected through semi-structured interviews, observation, and documentation. The informants included parties directly involved in procurement activities, namely the Purchasing Manager, Purchasing Supervisor, Purchasing Staff, Receiving Staff, and user departments. Data were analyzed through data reduction, data display, and conclusion drawing and verification. The findings show that the goods procurement SOP has been implemented in a structured manner through Purchase Requisition submission, document approval, Purchase Order issuance, supplier ordering, and goods inspection by the receiving department. The SOP is effective in supporting hotel operational needs and relatively consistent because control stages are maintained even under urgent requests. However, efficiency has not been fully optimized because administrative and approval processes still rely on a manual paper-based system. Other barriers include inventory data input errors, supplier stock limitations, customs constraints, and weather-related distribution disruptions. This study recommends the implementation of e-procurement, stronger interdepartmental coordination, improved inventory data accuracy, and supplier diversification.

This study aims to evaluate user satisfaction with the Customer Service Management System (CSMS) at PT Jaya Abadi Kontrindo using the End User Computing Satisfaction (EUCS) method. The CSMS is utilized to support various operational activities, such as purchase requests, payment requests, accounts receivable management, sales order rescheduling, and digital report generation. However, the system still faces several issues, including suboptimal response time, lack of user guidance, and the absence of a specific evaluation of user satisfaction. This study employs a qualitative approach by distributing questionnaires to 50 CSMS users using purposive sampling. The instrument was developed based on the five EUCS dimensions, namely content, accuracy, format, ease of use, and timeliness. The collected data were analyzed using validity testing, reliability testing, mean-based descriptive analysis, and Spearman correlation analysis. The results show that all questionnaire items are valid and reliable. In addition, all EUCS dimensions fall into the satisfied category, with the highest score in ease of use and the lowest in content. The Spearman correlation results also indicate that all EUCS dimensions have a significant relationship with user satisfaction.

The concrete block business is one of the micro-enterprises that develops in Wairotang Village and plays an important role in fulfilling the community’s need for building materials. However, in its development, sales fluctuate from year to year, which is assumed to be influenced by the level of consumer trust and the quality of the products produced. In addition, several problems still occur, such as concrete blocks that crack easily, inconsistent sizes, and varying levels of strength, leading consumers to hesitate in making repeat purchases. This study aimed to determine the influence of consumer trust and product quality on purchasing decisions of concrete blocks in Wairotang Village. The independent variables in this study were consumer trust and product quality, while the dependent variable was purchasing decision. This study was motivated by fluctuations in concrete block sales and the persistence of consumer doubts regarding product quality, including easily cracked blocks, inconsistent sizes, and varying strength levels. These conditions resulted in suboptimal consumer trust, which in turn affected purchasing decisions. This study used a quantitative research method. The population consisted of consumers of concrete blocks in Wairotang Village, and the sampling technique was purposive sampling. Data collection was conducted through questionnaires, observations, interviews, and documentation. The data were analyzed using descriptive analysis, validity tests, reliability tests, classical assumption tests, multiple linear regression analysis, t-tests, F-tests, and the coefficient of determination ($\text{R}^2$). The results were expected to show that consumer trust and product quality have a positive and significant influence on purchasing decisions of concrete blocks in Wairotang Village, both partially and simultaneously. A higher level of consumer trust and better product quality lead to increased purchasing decisions. Therefore, concrete block business actors will need to maintain product quality and build good relationships with consumers in order to improve purchasing decisions and ensure business sustainability.  

The rapid growth of digital technology and social media has reshaped communication practices, consumer behavior, and marketing approaches, particularly among Generation Z, who are widely recognized as digital natives. For this generation, social media serves as a major channel for obtaining information and exploring product references before making purchase decisions. In this environment, influencer marketing has emerged as a prominent promotional approach because it can foster audience interaction, emotional connection, and trust more effectively than conventional advertising. This study examines the role of influencer marketing in shaping the digital behavior of Generation Z in Indonesia. A qualitative literature review method was employed by analyzing secondary sources drawn from academic journals, books, and related publications. The findings indicate that influencer marketing has a meaningful influence on information-seeking behavior, decision-making processes, and the level of digital engagement among Generation Z. Influencers are commonly viewed as more credible, relatable, and authentic sources of information. Furthermore, the effectiveness of influencer marketing is determined more by credibility, authenticity, and the quality of interaction than by follower count alone. These findings suggest that companies should adopt digital marketing strategies that are more interactive, personalized, and relationship-oriented in order to engage Generation Z more effectively.

This study aims to analyze the influence of ready-to-use template designs, design consultation services, and the ease of online ordering on consumer purchasing interest at the Bahtera Batam Printing Shop, both partially and simultaneously. This study used a quantitative approach with a survey method. The population in this study was all consumers who made purchases at the Bahtera Batam Printing Shop, with a sample size of 123 respondents. The sampling technique used non-probability sampling with a purposive sampling method. Data collection was conducted through questionnaires measured using a Likert scale. Data were analyzed using multiple linear regression, hypothesis testing (t-test and F-test), and coefficient of determination testing using SPSS.The results of the partial test (t-test) indicate that ready-to-use template designs have a positive and significant effect on consumer purchasing interest (significance value 0.005 < 0.05). Design consultation services also have a positive and significant effect on consumer purchasing interest (significance value 0.002 < 0.05). Similarly, the ease of online ordering had a positive and significant effect on consumer purchase intention (significance value 0.001 < 0.05). Simultaneous testing (F-test) demonstrated that ready-to-use template designs, design consultation services, and ease of online ordering collectively had a positive and significant effect on consumer purchase intention at Bahtera Batam Printing Shop (significance value 0.000 < 0.05). Based on the coefficient of determination test (Adjusted R-square), 48.1% of the variation in consumer purchase intention was influenced by these three services, while the remaining 51.9% was explained by factors outside this research model.

Customer loyalty is an important factor in maintaining the sustainability of restaurant businesses amid increasingly intense competition in the culinary industry. This study aims to analyze the influence of service quality, product quality, and price on customer loyalty with customer satisfaction as a mediating variable at Waduk Malahayu Restaurant, Brebes. This research used a quantitative approach with a survey method through the distribution of questionnaires to 100 respondents who were customers of Waduk Malahayu Restaurant. The sampling technique used was accidental sampling. Data analysis was conducted using the Partial Least Square (PLS) method with the assistance of SmartPLS version 3 software. The results of the study indicate that service quality has no effect on customer loyalty, product quality has no effect on customer loyalty, and price has a positive and significant effect on customer satisfaction. Customer satisfaction is unable to mediate the relationship between service quality and customer loyalty, while customer satisfaction is able to mediate the relationship between product quality and customer loyalty, as well as the relationship between price and customer loyalty. In addition, customer satisfaction has a positive and significant effect on customer loyalty. These findings indicate that product quality, price suitability, and customer satisfaction are the main factors in increasing customer loyalty at Waduk Malahayu Restaurant, Brebes. Therefore, the restaurant management needs to maintain product quality, improve service, and set appropriate prices in order to retain customer loyalty and encourage repeat purchases in the future.

The lack of a systematic calculation approach makes it difficult for APR Nine to monitor fabric raw material inventory, resulting in raw material purchases still being based on habit and intuition. With a total inventory of 2,001 rolls and raw material usage of 1,803 rolls of fabric, there were seven times of excess stock and five times of shortage during the period of October 2024 to September 2025. The difference between the two was 198 rolls. This study uses the Economic Order Quantity (EOQ) method to analyze fabric raw material inventory control. This study uses a quantitative approach with descriptive analysis using data from the period of October 2024 to September 2025. The results of the study indicate that 1694 orders with an ordering frequency of 10 times, a safety stock of 29 rolls, and a reorder point of 35 rolls are the ideal quantities when using the Economic Order Quantity (EOQ) approach. Compared to the previous APR Nine approach, the application of the Economic Order Quantity (EOQ) method is more effective in reducing overall inventory costs from Rp. 5,011,949.35 to Rp. 4,508,824.67.

This study aimed to analyse the impact of customer service quality on sales at CV BILCA Digital Printing in Maumere for the 2024-2025 period. Grounded in the SERVQUAL model, this qualitative research posits that the five dimensions–responsiveness, reliability, empathy, assurance, and tangibles–synergistically build customer trust, which in turn drives repeat purchases and word-of-mouth (WOM). The study involved 15 customers selected through purposive sampling. Data were collected via in-depth interviews, participant observation, and internal documentation. Analysis was conducted using the Miles & Huberman model, encompassing data reduction, display, and conclusion drawing. The findings confirm that all five SERVQUAL dimensions collectively cultivate trust, leading to increased repeat purchases and positive WOM. Key results reinforce a “Trust Chain” mechanism: response times of ≤30 minutes and on-time production foster initial trust; personalized interactions strengthen affective bonds; and robust recovery policies reduce perceived risk by exceeding expectations. Notably, no instances of customer churn were observed, as all participants made repeat orders within 24 hours of a positive experience. This study contributes to the services marketing literature by empirically validating trust as a key mediator between service quality dimensions and behavioural outcomes, while also offering a replicable empirical model for Micro, Small, and Medium–sized Enterprises (MSMEs) in the digital printing sector.

Traditional association rule analysis is effective at uncovering co-purchase patterns but fails to provide a global structural view of the market, which often results in fragmented and isolated insights. This study proposes a hybrid framework that integrates the Apriori algorithm with a Minimum Spanning Tree (MST) in order to validate and contextualize association rules within a single structural backbone. Transaction data from a retail store are transformed into a weighted, undirected product graph using an inverse-support function, and an MST is then extracted to represent the market backbone, while frequent itemsets and strong rules are obtained using Apriori. Experimental results on 236 multi-item transactions show that the MST backbone comprises 10 products and 9 fundamental links, with 66.67% of these links being confirmed by strong association rules, indicating a substantial coherence between statistical and structural evidence. The proposed model identifies 41 Apriori patterns that can be embedded in the MST and ranks them using a new metric, Structural Distance, which enables the categorization of Core Patterns, Bridge Patterns, and Complex Patterns according to their structural tightness. This hybrid perspective distinguishes dense, strategically meaningful bundles from anomalous but frequent combinations that are structurally peripheral, thereby offering a more holistic and actionable alternative to conventional Market Basket Analysis. The validated framework can support various applications, including store layout optimization, cross-selling strategies, and the design of path-based recommender systems, and it opens avenues for future extensions based on dynamic graphs and Graph Neural Networks.

This study analyzes the influence of Digital Marketing Strategy and Brand Image on consumer purchasing decisions and tests the role of Brand Awareness as a moderating variable at Moringa Coffee and Eatery. Data collection was conducted using a Likert scale questionnaire and processed using SmartPLS 4.0 with a quantitative PLS method approach. The results show that Digital Marketing Strategy and Brand Image have a significant effect on purchasing decisions. However, Brand Awareness does not act as a moderating variable because it does not strengthen the relationship between the two on Purchase Decisions. These findings emphasize the importance of optimizing digital marketing strategies and strengthening brand image, as well as the need to increase brand awareness in order to support the effectiveness of marketing strategies. Furthermore, the study highlights that consumers tend to make purchasing decisions based on the perceived value and credibility presented through digital platforms, making consistent online engagement crucial. Improving brand awareness may require more targeted promotional activities, interactive content, and customer involvement to build a stronger emotional connection with the brand. Overall, these results provide valuable insights for managers aiming to enhance competitiveness and customer loyalty in the digital marketplace.

This research investigates the application of the Economic Order Quantity (EOQ) method to improve drug inventory management in a primary hospital pharmacy, with a particular focus on reducing storage costs. A descriptive quantitative approach was applied using secondary data from January to December 2024, covering annual demand, purchase price, ordering cost, and holding cost. The analysis concentrated on fast-moving vital essential and moderate vital drugs that are critical for sustaining patient treatment. The study revealed inefficiencies in the hospital's procurement practices, with some medicines simultaneously facing overstock and stockout risks, indicating weak planning. EOQ calculations provided alternative procurement quantities that were smaller but more frequent, resulting in lower storage costs and better stock control. Simulation outcomes demonstrated notable cost savings, particularly for Flamicort, Diazepam, and Ventolin. These findings emphasize the value of integrating EOQ into hospital pharmaceutical logistics to reduce financial losses, strengthen supply chain efficiency, and ensure the continuous availability of essential medicines in primary hospital settings.

EOQ calculations suggested lower and more frequent procurement, reducing storage costs and improving stock control. The findings demonstrated that applying EOQ could minimize financial risks, optimize resource allocation, and ensure continuous access to essential medicines. This research highlights the relevance of structured inventory models in supporting hospital efficiency and sustainable pharmaceutical logistics, particularly in resource-limited primary hospitals.

This study aims to compare two methods of raw material inventory management, namely Economic Order Quantity (EOQ) and Periodic Order Quantity (POQ), in improving efficiency and reducing operational costs at Konveksi Arey Hijab. The main problem faced by this company is the irregularity in raw material inventory management, which causes wasteful costs, especially ordering costs and storage costs. Based on raw material purchase data in 2024, which recorded a total purchase of 26,203 kg with a total cost of IDR 1,834,573,300, this study uses a descriptive quantitative approach to compare the two methods. The results of the study show that the EOQ method produces lower inventory costs, namely IDR 16,568,074, compared to the POQ method. The application of the EOQ method can reduce the frequency of excessive ordering, while the POQ method is more effective for ordering periods that are adjusted to seasonal demand. This study recommends that Konveksi Arey Hijab adopt the EOQ method to optimize raw material inventory management, reduce wasteful costs, and improve the company's operational efficiency.
