Abstract

This study aims to analyze the effects of service failure and service recovery on customer satisfaction and repurchase intention among Shopee Xpress users in the Greater Bandung area. Using a quantitative approach with PLS-SEM via SmartPLS, data were collected from 150 active users. Results show that both service failure and service recovery significantly affect customer satisfaction but do not directly influence repurchase intention. Customer satisfaction has a strong and significant effect on repurchase intention and mediates the relationship between service failure and recovery toward repurchase behavior. These findings highlight the importance of service quality improvement and responsive recovery strategies to build customer loyalty in Indonesia’s competitive e-commerce logistics sector.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) play a vital role in Indonesia’s economy, yet they continue to face challenges in inventory management. One of the main challenges is the inaccuracy of stock recording due to the use of manual stock-taking methods, which are time-consuming, prone to errors, and result in inconsistent data. This condition affects business operations, such as overstocking or stockouts, leading to inefficient management and potential financial losses. This study aims to design and develop a Web-Based Stock Opname Information System to improve the accuracy and efficiency of inventory recording in MSMEs. The system development adopts the waterfall method, which consists of several stages: requirements analysis, system design, implementation, testing, and maintenance. Each stage plays a crucial role in ensuring the system aligns with user needs. The web-based system enables real-time stock monitoring, minimizes recording errors, and enhances operational efficiency. Through the implementation of this system, MSMEs are expected to optimize inventory management, reduce human error, and improve competitiveness in facing increasingly complex business challenges.

Abstract

Continuous Professional Development (CPD) for TVET teachers improves the quality of vocational education and ensures relevance to industry advances. This study presents a systematic literature review (SLR) of CPD research trends for TVET teachers over the last ten years (2013-2023), with particular attention to how different CPD models impact classroom effectiveness. Using the PRISMA procedure, article searches were performed in the Scopus database, yielding 48 publications suitable for further study. Despite a large increase in CPD publications, research in developing countries remains scarce, with significant disparities in implementation approaches between developed and developing educational systems. Qualitative approaches dominate methodologically, with apprenticeships, education, and training emerging as primary topics. However, the review reveals limited research on measuring the direct impact of CPD on teacher performance and student outcomes across different educational contexts. These findings point to the need for more integrated, locally based CPD strategies with stronger industry partnerships to enhance the effectiveness and relevance of professional development for TVET teachers. The study provides a foundation for policymakers and researchers seeking to develop context-specific CPD frameworks that balance theoretical knowledge with practical teaching improvements in technical and vocational education.

Abstract

Work-Integrated Learning (WIL) has become essential in vocational education for bridging academic learning with workplace experience. This systematic review analyzes 61 articles on WIL frameworks published between 2019-2024 using the PRISMA protocol. The analysis identifies five main types of WIL frameworks: Competency-Based Framework (focusing on industry-relevant competencies), Integrated Evaluation Framework (emphasizing comprehensive assessment), Industry-Academic Collaborative Framework (developing effective institutional-industry partnerships), Technology-Enhanced WIL Framework (utilizing technology to expand learning experiences), and Field-Specific Pedagogical Framework (tailoring approaches to specific disciplines). Publication trends show significant growth in WIL framework research, with a peak of 17 articles in 2024, reflecting increasing recognition of work-based learning's importance. The review reveals several research gaps, including limited investigation of technology integration's long-term impact, need for multi-stakeholder evaluation approaches, frameworks that effectively combine various WIL modalities, limited understanding of cross-disciplinary framework transferability, and frameworks that systematically incorporate evolving workforce demands. These findings provide direction for future WIL framework development and implementation, Contributing to more effective integration of academic learning with practical work experience in vocational education, these findings provide valuable direction for the future development and implementation of Work-Integrated Learning frameworks.

Abstract

This study aims to obtain digital competency data for vocational school teachers, digital training that has been attended by vocational teachers, the use of digital infrastructure, and the readiness of schools to face digitalization. The research method used is ex-post facto through a survey with a quantitative descriptive approach. The survey was conducted on 39 teachers at SMKN 8 Bandung. Data is collected through a questionnaire using the Google form. The results of the study showed that the digital competency of vocational school teachers was quite good. On average, 67% of vocational teachers already have digital competence. Teachers who have attended training related to digital competence obtained data of 32%. All teachers have utilized digital infrastructure in schools, but this has not been done optimally. A small number of teachers still experience difficulties in utilizing digital learning infrastructure. School readiness in preparing for digitalization of learning obtained data of 76%. These results show that the digital competency of vocational school teachers and school readiness in facing digitalization must be improved.

Abstract

Permintaan produk fashion yang bersifat musiman dan dipengaruhi oleh tren sering menimbulkan ketidaksesuaian antara jumlah produksi dan penjualan. Kondisi tersebut terjadi di PT XYZ khususnya pada produk casual jeans, di mana volume produksi secara konsisten melebihi penjualan dan terus meningkat setiap tahun. Ketidakseimbangan tersebut menunjukkan perlunya sistem peramalan yang mampu menggambarkan pola permintaan secara lebih akurat untuk mendukung perencanaan produksi dan pengendalian persediaan. Penelitian ini menggunakan metode kuantitatif dengan pendekatan komparatif untuk membandingkan performa metode Holt-Winters dan Seasonal Autoregressive Integrated Moving Average (SARIMA) dalam memprediksi permintaan produk casual jeans. Penelitian ini menggunakan data sekunder penjualan bulanan dari Januari 2022 hingga Desember 2024 yang dianalisis menggunakan perangkat lunak RStudio. Akurasi kedua model diukur menggunakan Mean Absolute Scaled Error (MASE) dan Mean Absolute Percentage Error (MAPE). Hasil penelitian menunjukkan bahwa metode Holt-Winters Additive menghasilkan nilai MASE sebesar 0,399 dan MAPE 2,97%, sedangkan metode Holt-Winters Multiplicative memiliki nilai MASE 0,228 dan MAPE 1,55%. Sementara itu, model SARIMA (0,1,1) (1,1,0) [12] menunjukkan kinerja terbaik dengan nilai MASE 0,216 dan MAPE 1,43%, yang merupakan tingkat kesalahan terendah dibandingkan metode lainnya. Dengan demikian, metode SARIMA lebih sesuai digunakan untuk memprediksi permintaan produk casual jeans dengan pola musiman, serta dapat menjadi dasar dalam pengambilan keputusan produksi yang lebih efisien di PT XYZ.

Abstract

Computational Thinking (CT) is the foundational discipline of informatics. Meanwhile, the Computational Thinking Scale (CTS) is a widely recognized instrument for measuring CT. However, despite its widespread recognition, only a limited number of studies have examined the reliability and construct validity of CTS among Indonesian students. Furthermore, linguistic equivalence across all CTS items is essential to avoid misinterpretation. Therefore, this study aims to adapt the CTS instrument into Bahasa Indonesia and conduct both reliability and validity testing. A total of 551 undergraduate students participated in this research. The statistical methods employed include Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). The results revealed that 9 out of 29 CTS items failed to meet the required criteria. The final model showed strong fit indices (CFI = 0.95, TLI = 0.96, RMSEA = 0.047, SRMR = 0.049), along with acceptable validity and reliability across all dimensions. These findings affirm that the Indonesian version of CTS is a robust and valid tool for assessing students' CT Skills.
