Abstract

The Total Productive Maintenance (TPM) approach is one of the main operational strategies to improve production efficiency and reduce maintenance costs. This article reviews the important role of TPM components, especially the Planned Maintenance System (PMS) and Computerized Maintenance Management System (CMMS), in supporting operational performance. The implementation of these systems involves structured data collection and systematic analysis to improve predictive and preventive maintenance. This article also highlights the success factors and obstacles to implementing TPM, PMS, and CMMS, including management commitment, employee training, technology integration, and challenges such as resistance to change and system complexity. The review results show that cross-functional collaboration, a continuous improvement mindset, and the use of advanced technology are the keys to success in optimizing equipment maintenance, reducing downtime, and increasing operational efficiency and cost effectiveness. Across reviewed studies, operational efficiency increased by 12–35% and maintenance costs decreased by 10–30% after adopting TPM, PMS, or CMMS. These findings emphasize the critical role of digital integration and proactive culture in maintenance optimization.

Abstract

This research evaluates the energy efficiency of the Aloe vera drying process using a Freeze Vacuum Drying (FVD) system, focusing on the thermal performance and the role of a Thermal Energy Storage (TES) unit with paraffin wax as the storage medium. Experiments were conducted with Aloe vera samples of 2 kg, 3 kg, and 4 kg to assess their effects on energy usage, Coefficient of Performance (COP), and moisture removal efficiency. The highest Specific Moisture Extraction Rate (SMER) was 0.132 kg.water/kWh for the 4 kg sample, with a Specific Energy Consumption (SEC) of 7.223 kWh/kg.water and a COP of 5.4. The energy efficiency peaked at 10.80%, achieved by incorporating TES. The results demonstrate that TES improves COP and reduces the specific energy demand, leading to a more energy-efficient drying process.
