Production quantity planning is a crucial component in the bottled water industry (AMDK) to ensure that consumer demand is met efficiently. Inaccuracies in determining the amount of production can lead to overproduction and supply shortages, which ultimately leads to increased operational costs and decreased customer satisfaction. This study applies the Sugeno fuzzy logic method to predict the amount of production based on two main variables, namely weekly demand and raw material stock. The analysis stages include the fuzzification process, the preparation of the rule base, inference using the zero-order Sugeno method, and defuzzification using the Weighted Average (WA) method. The data used is synthetic data that represents the operational conditions of the medium-scale bottled water industry. The results show that the Sugeno fuzzy system is able to produce production predictions that are adaptive and responsive to fluctuations in demand and stock availability. This model provides consistent and stable output, so it can help companies in determining the optimal production amount. These findings confirm that Sugino's fuzzy approach can be an effective decision support tool in bottled water production management, especially in the face of uncertainty and variability in market demand.

This study conducts a Systematic Literature Review (SLR) to examine how key dimensions of digital service quality—namely system quality, ease of use, perceived value, and payment availability—shape customer loyalty among Generation Z culinary consumers, with customer satisfaction functioning as the mediating variable. Bibliometric mapping reveals that previous studies have predominantly focused on Millennials and Gen Y and have emphasized traditional service quality rather than digital service performance, indicating a significant research gap in Gen Z–specific digital consumption behavior. The SLR findings show that fast, secure, stable, and user-friendly digital systems strongly influence perceived value and user satisfaction, while the availability of digital payments such as QRIS and e-wallets enhances seamless transactional experiences. Customer satisfaction emerges as the primary psychological mechanism mediating the relationship between digital service quality and Gen Z loyalty, reflected in repeat purchases, positive word of mouth, and emotional attachment to digital culinary platforms. This study contributes theoretically by addressing existing research gaps and proposing a conceptual model of Gen Z loyalty grounded in digital experience.

This study investigates the structural relationships among Product Quality (PQ), Brand Image (BI), Word of Mouth (WOM), and Repurchase Intention (RI) to empirically understand the sequential mechanisms driving consumer loyalty in a highly competitive market. Grounded conceptually in the Stimulus-Organism-Response (S-O-R) paradigm, the research posits that PQ acts as an external antecedent influencing RI through the mediating cognitive and behavioural constructs of BI and WOM. Data were collected from a sample of 187 Weber product consumers in Surabaya and analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM). The empirical results confirm all hypothesized direct and indirect relationships. Specifically, PQ significantly and positively influences both BI (β=0.337, p<0.000) and WOM (β=0.351, p<0.000). Furthermore, both BI and WOM significantly predict RI, with WOM (β=0.498, p<0.000) demonstrating a markedly stronger effect compared to BI (β=0.414, p<0.000). The model successfully explains a moderate 57% of the variance in Repurchase Intention. These findings underscore the strategic imperative for management to prioritize superior product quality, which organically fosters a positive brand perception and stimulates potent word-of-mouth promotion identified as the most critical driver of repeated purchases. Future research is encouraged to integrate additional affective factors, such as customer satisfaction or perceived price fairness, to enhance the explanatory power of the consumer loyalty model.

This study aims to analyze the influence of price, service quality, and product quality on consumer satisfaction at Herbal Medicine MSMEs in Pare, Kediri.

Service quality and product quality have a positive and dominant impact, while price shows a negative relationship, indicating that consumers remain sensitive to pricing changes. The model explains 76.4% of the variation in consumer satisfaction, confirming that maintaining service excellence and consistent product quality are key to improving satisfaction and loyalty among herbal medicine consumers.

Initial survey results show that consumers in the Makale region have specific preferences for tempeh packaging and quality, but business actors have not incorporated these preferences into their production and marketing strategies. This gap calls for an intervention to develop a strategy based on a systematic, contextual mapping of consumer preferences. Using a mixed methods approach with an explanatory sequential design, the study was conducted in two stages: first, quantitative data collection and analysis, followed by qualitative data collection and analysis to clarify and deepen the results. The study found that consumer preferences for Jeslyn tempeh are primarily influenced by sensory qualities (taste, texture, aroma), cleanliness, affordability, hygienic packaging, distribution ease, and promotion. The Likert scale analysis showed that most indicators had an average value above 4.20 (percentage index > 84%), indicating high to very high consumer satisfaction. Taste (mean 4.52; index 90.4%) and texture (mean 4.44; index 88.8%) were the most influential factors, followed by price and cleanliness. Consumer loyalty is built through consistent quality and emotional attachment to local products. Producers should maintain product quality, improve hygiene, introduce simple innovations, and use social media for cost-effective promotion.

The rapid growth of online transportation services has significantly transformed urban mobility patterns, including in Abepura District, Jayapura City. This study is grounded in the concept of smart mobility, which emphasizes technological integration, efficiency, and accessibility within the smart city framework. The theoretical foundation draws on consumer preference theory and the Customer Satisfaction Index (CSI) model. A quantitative approach was applied through questionnaires distributed to 100 respondents, supported by secondary data on digital infrastructure and local transport regulations. The analytical methods included conjoint analysis to identify user preferences, CSI analysis to assess smart mobility readiness, and spatial analysis to map infrastructure support. The findings indicate that fare and safety are the most influential attributes shaping user preferences, followed by application usability, transport mode, and travel time. Maxim emerged as the most widely used application, followed by Grab and Gojek. The CSI score reached 77.60%, categorized as “highly ready,” though gaps remain in intermodal integration and waiting time efficiency. Spatial analysis confirmed that the coverage of 16 BTS towers in Abepura adequately supports online transportation operations. In conclusion, online transportation services in Abepura District demonstrate strong readiness to support the implementation of smart mobility, yet further improvements are needed in modal integration and operational efficiency to ensure sustainable and inclusive urban mobility.

This study investigates the influence of coffee brewing device branding on the sensory perception of coffee flavor at TEFA Javanica, Politeknik Negeri Banyuwangi. Focusing on three V60 dripper brands—Hario (Japanese brand), Indotara (local generic brand), and One Two Cup (local brand with English naming)—the research employs an experimental quantitative approach combining blind and branded taste tests. The blind test eliminates brand influence, allowing assessment of the inherent coffee taste, while the branded test examines how brand expectations affect flavor experience and consumer perception. Sensory evaluation follows the Specialty Coffee Association's standardized cupping protocol, assessing aroma, taste, aftertaste, balance, and overall impression. Data from 45 purposively selected experienced coffee tasters were analyzed using the McNemar test to statistically compare preferences between blind and branded conditions. Results show significant brand effects on consumer perception for two of the three brands tested, highlighting branding’s role in shaping sensory experience. These findings offer valuable insights for coffee producers and marketers to optimize brewing device selection and branding strategies, enhancing customer satisfaction and competitive positioning. Academically, the study enriches literature on sensory branding in coffee, emphasizing the importance of equipment branding in specialty coffee markets. This research also lays groundwork for future studies exploring marketing and consumer psychology aspects within the specialty coffee industry.
