Abstract

Sampling methods are crucial for large-scale assessments. International surveys like PISA, TIMSS, and PIRLS use stratified random sampling (StRS) to enhance estimation accuracy, ensure representation of all subpopulations, and provide efficient administration. Similarly, Indonesia's National Assessment (AN) applies StRS, dividing populations by school size, class size, and gender. However, the accuracy of the AN sampling method, including its reliability and validity, has not been tested since its 2021 implementation. This study compares the reliability and validity of the AN sampling method to simple random sampling (SRS). Reliability is assessed by the consistency of estimates across repeated sampling, indicated by small standard error (SE) and confidence intervals (CI). Validity measures how accurately sample estimates reflect population parameters, evaluated through Mean Square Error (MSE). Using AN data from 1.9 million junior high school students out of 4.2 million, the analysis shows no significant differences in national population parameters between StRS and SRS. Both methods produce similar mean estimates (55) and standard deviations (10.7). However, StRS demonstrates greater variability in weights, reflecting its ability to account for sampling structure. At the school level, StRS outperforms SRS, yielding narrower CI and MSE ranges, highlighting its superior reliability. While MSE differences are statistically significant, their practical impact is minor due to the small effect size and large dataset. These results suggest StRS is more reliable for school-level reporting.

Abstract

This study aims to determine the most effective digital promotion strategy for increasing customer retention at Beauty Clinics. Five main criteria are set as the basis for assessment, namely engagement rate, content relevance, platform reach, customer feedback responsiveness, and conversion rate. This study involved five alternative digital promotion strategies: (1) interactive social media campaign, (2) digital loyalty program, (3) collaboration with influencers, (4) segmented paid advertising, and (5) SEO and website optimization. The assessment was conducted by five experts in the fields of digital marketing and beauty clinic management, utilizing a 4-point Likert scale. TOPSIS analysis was conducted through the stages of decision matrix normalization, weighting, determining positive and negative ideal solutions, and calculating Euclidean distance and preference values (Closeness Coefficient). The results showed that the interactive social media campaign strategy obtained the highest Closeness Coefficient value of 0.812, followed by the digital loyalty program (0.748) and collaboration with influencers (0.691). Meanwhile, the SEO website optimization strategy obtained the lowest value (0.581). These results indicate that a direct social interaction-based promotional approach is more effective in increasing customer loyalty in the service sector.

Abstract

The increasing adoption of digital beauty technology through Virtual Try-On (VTO) platforms powered by artificial intelligence (AI), augmented reality (AR), and virtual reality (VR) necessitates a precise understanding of user preferences. This study aims to model user responses to VTO features using Item Response Theory (IRT), specifically the Graded Response Model (GRM) for ordinal-scale items and the Nominal Response Model (NRM) for non-ordinal categorical items. A total of 15 items were analyzed using GRM to assess users’ perceptions of AI accuracy, feature convenience, and visual satisfaction. Additionally, five non-ordinal items were modeled using NRM to capture explicit preferences for specific VTO functionalities, such as digital interaction and visual simulation. The results show that the average user preference score was 3.02 out of 5 (SD = 1.03), while the total preference score averaged 60 out of 100 (SD = 10.7), with response distributions approximately normal (skewness = 0.12; kurtosis = -0.24). The item information curves from the GRM indicated that several items contributed high information (above 2.0), effectively differentiating users within the −1 to +1 ability range. In the NRM analysis, the “real-time color visualization feature” exhibited the highest utility parameter (c = 1.98), indicating a strong user preference for this feature. The integration of GRM and NRM enables a more nuanced and flexible mapping of user preferences. This study presents a novel psychometric approach by combining GRM and NRM within a single VTO context to simultaneously capture both ordinal and nominal dimensions of user experience, which has not been extensively explored in prior research. These findings provide meaningful insights for the development of adaptive, personalized, and intelligent AI-based VTO systems to enhance the quality of user experience in digital beauty applications.

Abstract

Era digital telah membawa perubahan mendasar dalam strategi pemasaran, di mana data analytics menjadi fondasi utama untuk mendukung pengambilan keputusan yang lebih efektif. Penelitian ini bertujuan untuk menganalisis pengaruh data analytics terhadap pengembangan pemasaran, khususnya dalam konteks usaha mikro, kecil, dan menengah (UMKM) di Indonesia. Metode yang digunakan adalah studi literatur dengan membandingkan fenomena empiris dan pendekatan teoretis dari berbagai penelitian terdahulu. Hasil kajian menunjukkan bahwa data analytics berperan signifikan dalam meningkatkan efektivitas segmentasi, targeting, dan positioning (STP), sekaligus memperkuat customer engagement dan brand awareness melalui personalisasi serta interaksi digital yang lebih relevan.Selain memberikan peluang strategis, penelitian ini juga menemukan adanya tantangan besar dalam penerapan data analytics di sektor UMKM. Hambatan yang dihadapi meliputi rendahnya literasi digital, keterbatasan infrastruktur, biaya implementasi, serta resistensi budaya organisasi. Faktor-faktor ini memperlihatkan adanya kesenjangan antara teori yang menekankan pentingnya data analytics dengan realitas implementasi di lapangan. Meskipun demikian, dengan dukungan regulasi pemerintah, penguatan literasi digital, serta pendampingan teknis dari berbagai pihak, tantangan ini dapat diatasi sehingga UMKM dapat memaksimalkan manfaat data analytics.Implikasi teoretis dari penelitian ini adalah memperkaya literatur pemasaran digital dengan menegaskan peran data analytics sebagai sumber daya strategis yang mendorong agility dan integrasi omnichannel. Sementara itu, implikasi praktisnya adalah memberikan rekomendasi bagi UMKM untuk menjadikan data analytics sebagai bagian inti dari strategi bisnis dalam menghadapi persaingan global. Penelitian ini menyimpulkan bahwa data analytics bukan sekadar alat analisis, tetapi pilar penting dalam membangun keberlanjutan bisnis dan keunggulan kompetitif di era digital. Keywords: Data analytics, pemasaran digital, customer engagement, UMKM.
