Abstract

The digital transformation of Total Quality Management (TQM) represents a paradigm shift from traditional manual practices to data-driven, intelligent quality systems. This systematic literature review (SLR) examines the trajectory of TQM digitalization by analyzing 52 peer-reviewed articles published between 2011 and 2023. The review explores three main themes: (1) the transition from traditional to digital and intelligent quality tools; (2) the enablers and barriers to implementing digital TQM, including technological readiness, organizational culture, and data infrastructure; and (3) the evolving role of quality professionals in the era of Industry 4.0. Findings show that while automation and digital tools improve efficiency and decision-making, successful integration requires strategic alignment of human, technological, and managerial capabilities. The study also highlights gaps in empirical evidence regarding the long-term impact of smart quality systems on organizational performance. This review contributes to the understanding of digital quality transformation, and provides a conceptual framework to guide future research and practical implementation in quality management.

Abstract

Peningkatan efektivitas peralatan produksi merupakan tantangan utama dalam industri manufaktur, khususnya pada sektor Non-Metallic Mineral Product seperti paving block yang menuntut konsistensi kualitas dan ketepatan waktu. Mesin press sebagai inti proses pembentukan produk kerap menjadi titik kritis yang menentukan keberhasilan output. Penelitian ini bertujuan mengevaluasi kinerja mesin press paving block di PT XYZ melalui pendekatan terintegrasi Total Productive Maintenance (TPM), pengukuran Overall Equipment Effectiveness (OEE), identifikasi Six Big Losses, serta analisis potensi kegagalan menggunakan Failure Mode and Effect Analysis (FMEA). Hasil analisis menunjukkan bahwa nilai OEE masih berada di bawah standar industri, dengan kerugian terbesar berasal dari Reduced Speed Losses dan Setup and Adjustment Losses. FMEA mengidentifikasi komponen-komponen kunci yang memengaruhi keandalan sistem, terutama pada unit penggerak dan sistem hidrolik yang memiliki nilai RPN tertinggi. Rendahnya efektivitas disertai gangguan operasional yang berulang mengindikasikan kelemahan sistem pemeliharaan yang masih reaktif serta kurangnya integrasi prosedur standar. Oleh karena itu, implementasi TPM secara menyeluruh dengan fokus pada penjadwalan perawatan, penyusunan standar setup, serta pelibatan aktif operator dalam pemeliharaan mandiri sangat disarankan. Pendekatan ini diharapkan mampu meningkatkan keandalan mesin, mengurangi pemborosan produksi, dan mendorong pencapaian efektivitas sistem secara berkelanjutan.

Abstract

Spent coffee grounds are organic waste that have the potential to be developed as raw material for biomass briquettes. This study aims to examine the effect of binder type, mixture ratio, and particle size on the characteristics of spent coffee grounds briquettes. Testing included calorific value using the Bomb Calorimeter method based on ASTM D 240-02, as well as moisture and ash content using the Gravimetric method. Results show that binder type was the most dominant factor. Briquettes with guar gum binder produced the highest average calorific value of 17,043.5 J/g (specimen 1) and the lowest ash content of 1.27 %wt, far superior to combustion residue briquettes, which yielded only 10,352.5 J/g with 28.78 %wt ash content. Fine particle size (<200 mesh) was shown to improve calorific value, while increasing the proportion of spent coffee grounds in residue-based briquettes effectively reduced ash content. All specimens exhibited moisture content below 15 %wt.
