This research aims to formulate a business development strategy for AK Laundry, a micro, small, and medium enterprise (MSME) located in Palembang that operates in the laundry service industry. As competition in this sector continues to intensify, MSMEs are required to adapt quickly through effective strategic planning. The study employed a descriptive qualitative approach, with data collected through interviews, direct observations, documentation, and questionnaires, ensuring a holistic understanding of both internal and external conditions.

The main objective of this study is to analyze business innovation implemented by Coffee Shops in Coblong District, Bandung City, considering the increasing number of similar businesses emerging, triggering fierce competition in this industry. In facing these conditions, business actors are required to continue to innovate to be able to survive and excel in the competition. This study uses a descriptive analysis method with an approach to calculating the average value of each variable measured using a Likert scale. The study population consisted of 38 Coffee Shop entrepreneurs who served as research samples. Based on the analysis results, business innovation was measured through four main indicators, namely relative advantage, compatibility, dissemination, and communicability. In general, Coffee Shops in this area have succeeded in innovating well, although there are variations in achievement for each indicator. The indicator with the highest score is communicability, which refers to the ability of staff, especially baristas and cashiers, to interact with customers in a friendly, polite, and effective manner. This is not only limited to greeting but also creating a comfortable atmosphere so that customers feel appreciated, which ultimately increases customer loyalty. Conversely, the indicator with the lowest score is dissemination, which indicates that most customers tend to only order a specific type of coffee without exploring other menu variations. This condition can be seen as an opportunity to strengthen superior products, but also signals that the product diversification strategy is not running optimally. Therefore, it is important for coffee shop businesses in Coblong to develop a menu diversification strategy, both in terms of beverage types and service variations, so that the business remains competitive, relevant to diverse consumer preferences, and able to increase competitiveness amidst the increasingly rapid growth of the coffee shop industry.

The increase in customer complaints in e-commerce services requires an effective excellent service strategy to maintain customer trust and loyalty. This study aims to analyze the complaint handling strategy at PT. XYZ. This study uses a descriptive qualitative method with in-depth interview techniques on four respondents who have different roles in customer service management. The results show that the most common complaints include product discrepancies, delivery delays, and slow refund processes. The main challenges include limitations in digital systems, interdepartmental coordination, and limited human resources. This study suggests optimizing customer service technology, strengthening internal coordination, and enhancing human resources to support 24/7 service and reinforce the company's image. Product discrepancies often arise from miscommunication between the sales and warehouse departments, leading to customers receiving products that do not match their expectations or the descriptions provided. Delivery delays are a common frustration, particularly during high-demand periods, affecting customer satisfaction and leading to negative reviews. Additionally, slow refund processes create frustration for customers, especially when dealing with returns or faulty products. These delays hinder the company's ability to provide excellent service and detract from the customer experience. One of the primary challenges identified in the study is the limitation in the digital systems used for customer service management. PT XYZ’s current system is not fully optimized to handle high volumes of complaints, leading to delays in responses and resolutions. Interdepartmental coordination is also a significant issue, as different departments such as logistics, sales, and customer service often operate in silos, making it difficult to resolve customer issues promptly.

This strategy helped foster trust and loyalty, as customers felt valued and personally attended to. The event was promoted not only through traditional marketing tools but also through word-of-mouth, leveraging employees' personal networks to spread the message. The study also highlights the role of digital marketing tools in enhancing the reach of the hotel's communication efforts. By utilizing platforms like Instagram, Facebook, and WhatsApp, Adhiwangsa Hotel was able to reach a broader audience, particularly among younger consumers who are more active on social media. These platforms allowed for real-time updates, engagement, and interaction with potential customers, making the event more dynamic and accessible. Overall, the success of the "So Kiss Me" event can be attributed to the hotel's effective use of integrated marketing communications, where personal selling played a significant role in delivering a more personalized and direct message to potential customers.

The concept of market orientation is an important cornerstone in modern marketing strategies, where companies not only focus on a deep understanding of customer needs, but also actively monitor competitors and maintain internal coordination between departments. Jaworski and Kohli (1993) emphasized that market orientation is one of the key factors that can affect a company's performance. Through the use of market information, companies can adjust their business strategies to meet current customer needs while anticipating future needs. A strong market orientation is believed to be able to make a significant contribution to increasing the company's competitiveness in the long term. However, if market orientation is based solely on materialistic goals and worldly gains, then the value of sustainability and societal well-being is often overlooked. From an Islamic perspective, market orientation needs to be based on sharia values, especially the principle of maslahah. This concept emphasizes that every business activity must bring benefits, avoid harm, and be in harmony with maqasid al-shariah, which is to protect religion, soul, intellect, descent, and property. Thus, market orientation is not only directed at the fulfillment of customer satisfaction and competitive advantage, but also at the achievement of blessings and social welfare. The integration of maslahah values in market orientation gives birth to the concept of Maslahah Market Responsiveness, which is the ability of companies to respond quickly and appropriately to market dynamics while still being based on ethics and social responsibility. This is an advantage in itself because it not only improves marketing performance, but also strengthens the company's image as a trustworthy and ethical entity. By combining conventional market orientation and sharia values, companies can build a sustainable competitive advantage, increase customer satisfaction, and make a positive contribution to society at large.

Companies should focus on enhancing these three aspects in order to build stronger customer loyalty. The results of this study can serve as valuable insights for businesses, particularly in the smartphone industry, to improve their customer retention strategies by strengthening brand loyalty through effective brand management practices.  

This study aims to analyze customer satisfaction with the Byond by BSI service at PT Bank Syariah Indonesia Tbk KCP Palembang KM 6, focusing on the influence of service quality and security. The research population consisted of 2,800 customers, with a sample of 97 respondents selected through purposive sampling. A quantitative approach was employed, using a structured questionnaire as the primary data collection instrument. The collected data were analyzed using multiple linear regression, accompanied by instrument testing, classical assumption testing, as well as t-test, F-test, and the coefficient of determination (R²).

The regression coefficient shows that security has the most dominant effect, with a value of 0.427, which is higher than the influence of service quality. This highlights that the sense of safety in conducting digital transactions is the primary concern for customers when using Byond by BSI services. The implications of this study emphasize the importance for banks to continuously improve the quality of digital services, particularly in terms of responsiveness, speed of access, and ease of use of the application. In addition, strengthening digital security mechanisms, including customer data protection, transaction encryption, and early detection of potential cyber threats, is crucial in building and maintaining customer trust. The study further underlines the need for continuous improvement in both service quality and security systems as a key strategy to address the challenges of digital banking transformation in an increasingly competitive environment. Therefore, this research contributes to the development of Islamic banking management strategies that focus on customer satisfaction and loyalty in the digital era.

This study aims to analyze the effect of relationship marketing on customer loyalty with customer satisfaction as a mediating variable at Sky Beauty Care Surabaya. Relationship marketing, which encompasses aspects of trust, commitment, communication, and complaint handling, has been identified as an important strategy in building long-term relationships with customers. In this study, a quantitative approach was used with a survey method, where data was collected through questionnaires distributed to customers who have used Sky Beauty Care services. The analysis results show that relationship marketing has a significant effect on customer satisfaction. The trust built between customers and the company, the company's commitment to providing the best service, clear and open communication, and prompt and effective complaint handling all contribute to increased customer satisfaction.

Customers who are satisfied with the service they receive are more likely to use the service again and recommend it to others, ultimately strengthening the customer's relationship with the company. These findings provide an important contribution to Sky Beauty Care in formulating more effective marketing strategies. Better implementation of relationship marketing can increase customer satisfaction and loyalty, which ultimately has a positive impact on business sustainability and growth.

This study discusses the phenomenon of silent lead in digital marketing strategy Amanah Bunda Daycare Semarang. This phenomenon refers to potential customers who have made an initial interaction through WhatsApp Business After seeing Meta Ads ads, but then do not continue communication or convert into customers. The phenomenon of silent leads is an important concern because although the digital marketing process manages to reach the target audience and trigger an initial response, the interaction does not continue until the purchase or registration stage of the service. This study uses a descriptive qualitative approach to explore the characteristics of passive behavior. The Data was collected through in-depth interviews with the internal manager of Amanah Bunda Daycare and five informants identified as silent leads. The results showed that the passive attitude of potential customers is influenced by several main factors, namely the location that is considered less strategic or too far, the perception of prices that are considered high, personal conditions such as changes in plans or time constraints, as well as the quality of customer service communication that is perceived to be less than optimal in providing responses, information, and personal approach. This phenomenon has not been fully accommodated in classic conversion models such as Aida (Attention, Interest, Desire, Action) and model 5A (Aware, Appeal, Ask, Act, Advocate). This shows that there are gaps in marketing communication strategies, especially in managing potential customers who initially respond positively but stop before conversion. Therefore, this study recommends the development of a more empathetic, structured and sustainable approach to communication. Suggested strategies include improving customer service systems based on quick response and personalization, implementing polite but consistent follow-up strategies, and composing marketing content that is able to build trust and emotional connection with potential customers. With these measures, it is expected that silent leads can be minimized and conversion rates increased significantly.

This way, long-term relationships with customers can be maintained and customer loyalty can be enhanced.

Customer loyalty is a crucial pillar in the banking industry, especially amidst increasingly fierce competition and rapid digital transformation. Loyalty not only reflects brand attachment but also reflects the level of customer trust and satisfaction with the services provided. This study aims to analyze the role of customer value and service quality in building customer loyalty, with customer satisfaction as an intervening variable. The study was conducted at the BRI Tabanan Branch using a quantitative approach. The research sample consisted of 383 respondents selected using the Krejcie and Morgan formula. Data were collected through questionnaires, interviews, and documentation, then analyzed using path analysis to examine the direct and indirect relationships between variables. The results show that customer value and service quality significantly influence customer satisfaction. Both variables also have a direct effect on customer loyalty, while also exerting an indirect effect through customer satisfaction as a mediating variable. In other words, increasing perceived value and service quality not only drives satisfaction but also strengthens loyalty, both directly and through the effects of satisfaction. These findings emphasize the importance of strategies to increase value and service quality as an effort to maintain loyalty amid changing customer preferences and digital disruption. For banking practitioners, the implications of this research can serve as a reference in designing more personalized, value-oriented, and technology-based service programs to increase long-term customer retention and strengthen competitiveness in an increasingly competitive market.

This study aims to comprehensively examine the effect of service quality and customer value on customer satisfaction, while also exploring the role of trust as a moderating variable. The focus of the research is on participants of the Digital Marketing Independent Internship at PT Satukelas Adhyapana Nusantara, Jakarta. An explanatory quantitative approach was employed, involving 87 respondents selected through purposive sampling. The collected data were analyzed using the Partial Least Squares Structural Equation Modeling (PLS-SEM) method with the assistance of SmartPLS 4 software. The results indicate that both service quality and customer value have a significant positive effect on customer satisfaction. Trust was also found to have a direct effect on satisfaction. However, the moderating role of trust was significant only in the relationship between service quality and customer satisfaction. In contrast, its moderating effect on the relationship between customer value and satisfaction was found to be statistically insignificant. These findings provide empirical support for the SERVQUAL theory, the concept of customer value, and the performance-expectations model, while also reinforcing literature that highlights the importance of trust in sustaining customer relationships. From a practical standpoint, this research emphasizes the need for strategies that integrate service quality enhancement with the delivery of perceived value, accompanied by efforts to build and maintain trust as a reinforcing factor for satisfaction. This combination of strategies is expected to enhance positive customer experiences, foster loyalty, and sustain long-term relationships. Furthermore, this study offers valuable contributions for developing marketing strategies and managing customer relationships in the digital education sector, which faces increasingly intense competition and challenges in the era of technological transformation and globalization.

Technological developments have penetrated various sectors of life, including in the transportation and communication lines in Indonesia. KAI Access is a digital service issued by PT Kereta Api Indonesia in the form of an application. This application is present as a strategic innovation to improve the convenience and comfort of customers in accessing various train services, from ticket bookings, schedule information, to cancellations and refunds. However, from the complaint data submitted by customers, there are two biggest problems that are often experienced, namely related to responsiveness and action from KAI Access which is considered slow in handling user complaints and technical problems.

Using a quantitative approach, with data collection techniques in the form of questionnaires, interviews, and literature studies, the respondents in this study were KAI Access users from the Edan Sepur train loving community. The results showed that the action variable had a positive and significant influence on customer loyalty, while the responsiveness variable did not have a significant influence directly. An important conclusion from this study is that in the context of digital applications such as KAI Access, customers prioritize concrete problem solving rather than just quick response. Therefore, PT KAI needs to strengthen concrete actions in handling complaints to increase long-term loyalty. Therefore, PT KAI needs to strengthen concrete actions in handling complaints to increase long-term loyalty, especially in the era of digitalization of public services that continues to grow rapidly.

The study aims to examine the influence of word of mouth (WOM) and customer relationship management (CRM) on customer loyalty at PT Garuda Sertifikasi Indonesia, with customer delight serving as a mediating variable.

This study aims to analyze the influence of Online Advertising on purchasing decisions for Skintific products by considering the mediating role of Trust and Social Media Engagement. Skintific, as a digital-native skincare brand, actively utilizes digital marketing strategies through various social media platforms such as Instagram, Tiktok, or e-commerce like Shopee to increase consumer appeal, especially in Malang City. This study uses a quantitative approach with the Partial Least Squares Structual Equation Modeling (PLS-SEM) method to test the relationship between variables. The sample was obtained through a purposive sampling technique with 114 respondents who are active consumers of Skintific. The results of this study indicate that Online Advertising has a significant effect on purchasing decisions, both directly and through the mediation of Trust and Social Media Engagement. Theoretically, this study extends the application of the Theory of Reasoned Action (TRA) in explaining the formation of attitudes and subjective norms of consumers towards digital advertising, as well as the Technology Acceptance Model (TAM) which shows how perceived ease and usefulness of digital advertising content affect user engagement. Customer Trust Theory in E-Commerce is used to explain how trust is formed in online transactions, while Relationship Marketing Theory emphasizes the importance of long-term interactions between brands and consumers. The Theory of Planned Behavior (TPB) expands this framework by adding the construct of behavioral control, which explains how consumers' perceptions of ease and barriers contribute to purchasing decisions. Social Influence Theory is used to understand the influence of social norms and online community opinions on purchase intentions, and Uses and Gratifications Theory (UGT) to examine consumer motivations in accessing and interacting with digital content based on information needs, affection, and self-identity. This research provides theoretical contributions in strengthening the relevance of integrating several consumer behavior theories in a digital context.
