Abstract

This study aimed to develop and validate a service quality measurement instrument specifically for brick-and-mortar cosmetic retail stores in Lampung Province, Indonesia. An initial pool of 40 items—reflecting six dimensions (store aesthetics, ambience, lighting, product display, store layout, and staff service quality)—was generated based on the literature and refined through expert review and pilot testing. Data were collected from 126 customers of three major cosmetic retailers in Lampung. Exploratory factor analysis (EFA) on 33 retained items revealed a stable three-factor structure (“Store Aesthetics,” “Ambience & Lighting,” and “Product Display, Layout & Staff Service”), explaining 70.6% of the total variance. Confirmatory factor analysis (CFA) confirmed model fit (CFI = 0.96; TLI = 0.95; RMSEA = 0.045; SRMR = 0.042). Each factor demonstrated high internal consistency (? ? 0.878; CR ? 0.90) and acceptable convergent validity (AVE ? 0.56) and discriminant validity. The final 26-item scale offers a psychometrically sound tool for assessing service quality in Indonesian cosmetic retail environments. Practically, managers can use this instrument to identify areas for improvement—in interior design, sensory ambience, merchandise presentation, store layout, and staff training—to enhance customer satisfaction and loyalty.

Abstract

This study assesses whether a multidimensional psychographic base that joins values, life visions, aesthetic styles, and media preferences can explain skincare consumer behavior in Indonesia and translate directly into brand decisions. A cross sectional online survey of two hundred seventy consumers employed seven-point scales for twelve value items, ten life vision items, nine aesthetic style items, and nine media preference items. The instrument showed satisfactory internal consistency with Cronbach’s alpha of 0.81 for values, 0.78 for life visions, 0.85 for aesthetic styles, and 0.78 for media preferences. Dimensionality was examined with principal components at the block level and audience segments were identified with Gaussian mixture models, with the number of classes selected by the Bayesian Information Criterion. The analysis yielded six interpretable segments. Values place holistic health, emotional balance, and environmental or ethical responsibility at the center of decision making. Aesthetic attraction is strongest for modern minimalism followed by classic and sporty codes, while luxury and futuristic codes are less salient. Media use concentrates on Instagram and TikTok with e-commerce and YouTube as important complements. These findings establish a direct bridge from latent motives to actionable levers by pairing claims and design languages with the media habitats in which persuasion occurs. Brand teams can emphasize health and calm narratives with credible testing, employ transparent and minimalist clinical visual systems, and activate creator led short video content with seamless handoff to e-commerce, while using longer instructional content for audiences that prefer YouTube and Facebook. Limitations include a youthful and digital first sample, self-report measures, and a cross sectional design. The study offers an empirically grounded baseline for psychographic profiling in skincare and a practical roadmap for audience in culture strategy that is both differentiated and repeatable.

Abstract

This research presents a comparative analysis of four popular sentiment classification models: Naive Bayes, Support Vector Machine (SVM), Long Short-Term Memory (LSTM) networks, and Bidirectional Encoder Representations from Transformers (BERT). The models are evaluated using the Amazon Product Reviews dataset based on their ability to classify sentiments into positive or negative categories. The results show that BERT outperforms the other models in accuracy, precision, recall, and F1-score, demonstrating its superior ability to capture complex contextual relationships in text. LSTM performed well, particularly in recalling positive sentiments, but was outperformed by BERT overall. Conversely, Naive Bayes and SVM exhibited lower accuracy and higher false positive rates, highlighting their limitations in handling nuanced, context-dependent text. This study emphasizes the trade-offs between traditional machine learning models and advanced deep learning techniques.

Abstract

The cosmetics industry has been experiencing rapid growth, driven by increasing consumer awareness of personal hygiene and self-care. Among personal care products, shower gels have gained significant market traction due to their convenience and perceived hygiene benefits compared to conventional bar soaps. This study evaluates the feasibility of establishing a shower gel manufacturing facility in Ketapang, South Lampung, by assessing key factors such as market potential, technical viability, financial sustainability, and regulatory compliance. The global shower gel market is projected to expand at a Compound Annual Growth Rate (CAGR) of 5.47%, reaching an estimated value of USD 70.88 billion by 2031. This trend is reflected in Indonesia, where demand for liquid personal care products has been steadily rising due to shifts in consumer lifestyles and increased disposable incomes. Despite the promising market outlook, the domestic cosmetics manufacturing sector faces challenges such as dependence on imported raw materials, supply chain inefficiencies, and limited local production capacity. This study examines whether localizing production in Ketapang, a region with access to natural resources and supportive industrial policies, can offer a competitive advantage. The research employs a feasibility study framework incorporating market analysis, technical assessment, financial modeling, and non-technical considerations. The financial analysis reveals that with an estimated production of 5,000 units per month, the facility is projected to generate IDR 523.2 million in revenue. The calculated cost of goods sold (HPP) per unit is IDR 87,204.86, with a selling price set at IDR 104,645.83 to maintain a 20% profit margin. Break-even analysis indicates that the facility must achieve a monthly sales volume of at least 7,500 units to cover all costs. The return on investment (ROI) is projected at 10.12%, with an estimated payback period of 9.88 years. The study also highlights regulatory requirements, including compliance with BPOM (Indonesian Food and Drug Authority) standards, Good Manufacturing Practices (GMP), and environmental sustainability protocols. Findings suggest that while the venture is financially and operationally viable, achieving profitability requires strategic interventions. These include securing local raw materials to reduce cost dependencies, optimizing production processes, implementing marketing strategies to increase brand competitiveness, and engaging policymakers for potential fiscal incentives. Overall, the establishment of a shower gel manufacturing facility in Ketapang presents a strong opportunity to tap into Indonesia's growing cosmetics sector while contributing to regional economic development.

Abstract

This study examines how an Indonesian organic-skincare SME integrates science-based storytelling, calibrated fear appeals, and micro-influencer collaboration on Instagram to build brand engagement and consumer trust. It addresses the research gap on balancing educational and threat-based messaging in emerging Muslim-majority markets. A 16-week single-case study combined (i) five semi-structured interviews, (ii) document analysis of a four-month content calendar (71 posts), and (iii) post-level Instagram analytics. Thematic coding (κ = 0.82) was integrated with non-parametric tests (Mann–Whitney) in a mixed-methods joint display. Scientific storytelling embedded in a five-stage content workflow lifted saves-to-view ratios and underpinned a 70 % repeat-purchase rate. Fear-appeal posts generated 1.2× more comments but provoked backlash unless paired with coping advice, supporting the Extended Parallel Process Model. Posts co-created with niche influencers achieved six-fold higher views (3,189 vs 524) and engagement rates (2.46 % vs 0.41 %) than stand-alone brand content. Resource-constrained beauty brands should (i) codify a science-first scripting routine, (ii) sequence “threat-then-solution” messages, and (iii) prioritize credibility-matched micro-influencers over costly macro endorsements. This study is the first to integrate live social-media analytics, internal workflow documents, and stakeholder interviews to test how scientific storytelling and fear appeals interact under influencer mediation in an emerging-market cosmetics context, extending content-marketing and fear-appeal theory.

Abstract

Skinimalism has gained visibility as a beauty trend promoting fewer products, fewer routine steps, and deliberate essentials. This study maps how skinimalism is narrated in Instagram hashtag posts using qualitative netnographic observation and descriptive content analysis. Forty caption entries were purposively sampled from the #skinimalism feed; after removing near-duplicates, 36 unique captions were analyzed. Captions were predominantly in English (63.9%), followed by Indonesian (25.0%) and other languages (11.1%), with #skinimalism appearing explicitly in 80.6% of captions. Dominant narrative categories comprised trend definition or education (30.6%), product promotion (27.8%), and routine guidance (22.2%). Nonexclusive thematic coding revealed routine simplification as the most prevalent element (66.7%), followed by natural look aesthetics (33.3%), while multifunctionality or hybrid product framing was relatively limited (11.1%). Actor cues were identifiable in many posts, including brands or commercial accounts (22.2%), creators or educators (19.4%), clinics or experts (11.1%), and individual users (8.3%), although 38.9% could not be clearly classified. Engagement assessed from visible comment excerpts (n = 40) indicated limited discourse, with half of the posts showing no comments and the remainder dominated by emotive or transactional responses. This limited engagement does not necessarily signal weak consumer interest but reflects Instagram’s role in stabilizing trend narratives through curated, authored content. Overall, the hashtag feed functions as a structured narrative field that reinforces skinimalism through procedural templates and marketing-aligned messaging rather than extended peer deliberation.
