Abstract

Detecting bearing defects at low rotational speeds remains a major challenge due to weak impulsive responses and dominant low-frequency components. This study evaluated the feasibility of using a standard industrial accelerometer (1 µA/ms², equivalent to 100 mV/g) for detecting outer race defects in bearings operating at 100–300 RPM. Experiments were conducted under both baseline and defected conditions using two mounting configurations: stud and magnetic. Vibration responses were analysed through overall values (velocity, acceleration, and shock pulse), spectral analysis, enveloped signals, and time waveform comparisons. Results show that standard accelerometers can effectively detect bearing defect signatures in low-speed machines (100–300 RPM), with diagnostic performance strongly influenced by the sensor mounting method. At 100 RPM, magnetic mounting occasionally recorded higher acceleration readings (?30%) due to uneven impulsive energy distribution and low-speed dynamic instability. At higher speeds (200–300 RPM), stud mounting produced stronger and more stable responses, with amplitudes about 2–8% higher than magnetic mounting, confirming its superior coupling rigidity. Spectral analysis alone was limited by broadband noise, while time waveform and envelope analyses revealed clearer defect-related impacts, particularly at 1× RPM and 2× BPFO. Overall, stud-mounted sensors demonstrated more consistent and reliable performance, validating their suitability for accurate and practical low-speed vibration monitoring.

Abstract

Overall Equipment Effectiveness (OEE) is a comprehensive measure to identify the level of productivity and performance of machines/equipments. Conventional approaches to OEE data processing, such as using Microsoft Excel, have limitations. Consequently, the data processing process becomes less efficient and prone to human error. This study aims to examine the application of OEE in the Manufacturing Industry, measurable performance gaps between conventional and real-time approaches. The methodology used in this study was based on a synthetic literature review to evaluate the effectiveness of both OEE approaches based on existing studies. The transition of OEE from mere calculations to dynamic, real-time, and integrated systems is a direct response to the increasing complexity and competitiveness of the modern manufacturing environment. This study can be used to identify areas for future development and as a reference for further research to provide a guide to OEE practitioners in implementing improvements.

Abstract

This study investigates the mechanical and macro structural performance of welded joints produced by Flux-Cored Arc Welding (FCAW) and Gas Tungsten Arc Welding (GTAW) on API 5L Grade B low-carbon steel pipes used in marine CO2 fire suppression systems. The experimental work involved tensile, bending, hardness, and macro structural tests to evaluate the influence of each welding process on joint integrity. Both FCAW and GTAW joints exhibited high mechanical strength, with ultimate tensile strengths of 506MPa and 516MPa, respectively, exceeding the minimum requirement for API 5L Grade B steel. Fracture occurred in the base metal rather than the weld zone, confirming the superior strength and sound fusion quality of the joints. GTAW demonstrated slightly higher tensile performance and cleaner weld morphology due to the controlled heat input and stable arc achieved with 100% argon shielding, whereas FCAW produced marginally higher hardness in the heat-affected zone due to CO?-induced cooling effects. Macro structural analysis revealed complete penetration and the absence of porosity, slag inclusions, or cracks in both processes. The results comply with AWS D1.1 and ASME Section IX standards, confirming that both welding methods or their hybrid application are suitable for producing safe, reliable, and regulation-compliant marine fire suppression pipelines.

Abstract

Every ship that sails must be repaired to maintain seaworthiness and the safety of its users. Ship repairs that are carried out will take a considerable amount of time, so planning and scheduling must be completed before the repair process begins. The scheduling process at the shipyard is generally still done manually, involving the creation of a list of repairs. It has the potential to cause delays and increase the costs incurred. The use of the Critical Path Method (CPM) is an option to improve the effectiveness and efficiency of the repair process in terms of time and labor, and of course, minimize costs. This study aims to determine the effect of using the critical path method in the ship repair process, utilizing a literature review of several scientific articles. Of the 15 articles used in this study, 14 reported that the use of the critical path method enhances the effectiveness and efficiency of the ship repair process.

Abstract

Industrial growth and the increasing number of transportations cause the need for oil to increase. The increasing need for oil is directly proportional to the waste produced, namely used oil. Used oil waste can be a replacement fuel, which is produced quite large every year. This research used a mixture of used oil and Pertamina Dex used as a modified diesel engine fuel. The purpose of this study was to analyze the exhaust emissions produced by modified diesel engines. The research was conducted by varying the percentage of the mixture of used oil and Pertamina Dex, namely the percentage of a mixture of P10 (90% used oil and 10% Pertamina Dex), P20 (80% used oil and 20% Pertamina Dex) and P30 (70% used oil and 30% Pertamina Dex). Tests on the calorific value of fuel and exhaust emissions, which are varied based on the power load at idle (0 W), 1,000 W and 2,000 W. The test results showed that the calorific values of fuel P10, P20 and P30 were 44,191 kJ/Kg, 48,648 kJ/Kg and 50,074 kJ/Kg respectively. From this research it is known that the best fuel mixture of P30 with a loading power of 0 W, which emits a value of CO of 0.03%, CO2 of 2.32%, and HC of 34.86%. The results showed that the P10, P20 and P30 fuels met the exhaust emission quality standards according to the applicable regulations where the resulting opacity emissions did not exceed 40%.

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 aims to enhance the performance of Palm Sugar Fiber (PSF) or Ijuk roofing by combining it with recycled High Density Polyethylene (HDPE) plastic as a binder and outer protective layer. The method was used an experimental study with several variations in fiber form and mass, followed by performance testing on temperature, noise, and mechanical properties (tensile, compressive, and impact strength). The results showed that the 40-gram long fiber variation provided the most optimal performance. The indoor temperature beneath the PSF roof was recorded at 38.2°C. The absolute thermal conductivity value was calculated at 0.23 W/m·K. In noise reduction tests, the PSF roof recorded 39.6 dB compared to 74.2 dB for zinc roofing. In terms of strength, the palm fiber roof achieved a tensile strength of 13.24 MPa and the impact strength of 3.16 Joules. Thus, the fiber (fiber) composite roof with HDPE binder demonstrates superior thermal and sound insulation capabilities, as well as sufficient mechanical strength, making it a promising environmentally friendly alternative for modern roofing materials.

Abstract

Hand tractors are crucial for small-scale farming in Indonesia, but prolonged manual operation leads to operator fatigue, reduced productivity, and safety risks. This study develops a wireless steering control system for a hand tractor using an Arduino microcontroller and NRF24L01 transceiver. The system features a handheld transmitter with joystick input and a tractor-mounted receiver that controls the throttle via a servo motor and steering/clutch mechanisms through solenoids. The design process included system architecture, hardware and power circuit development, software programming, prototype assembly, and testing. Results show that the system operates optimally within 1–2 meters and remains functional up to 8 meters, though with communication degradation (increased delay, packet loss, and reduced actuator accuracy). Key constraints identified include unstable power supply, NRF24L01 limitations, and inadequate solenoid drivers. Recommendations for improvement include using NRF24L01+ PA/LNA modules, separating power rails, and adopting MOSFET-based drivers to enhance reliability and safety.

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.
