A comparative analysis between IoT-equipped and non-equipped zones confirmed improved risk mitigation and supervisory responsiveness. These findings highlight the potential applications of IoT-based smart safety helmets as a promising wearable device for improving health and safety management in high-risk construction environments, aligned with the broader goals of Industry 4.0
Assessing Light Pollution from Streetlight Designs along Major Streets in Kota Kinabalu Towards Sustainable Urban Lighting
Get PDFLight pollution from streetlights is becoming an increasingly serious issue, impacting ecosystems, human health, and astronomical visibility. In Kota Kinabalu, efforts to address the effects of street lighting remain limited, resulting in low public awareness of its consequences. This study examined light pollution in two major streets in Kota Kinabalu: Jalan Tun Fuad Stephens and Jalan Pasir by measuring the brightness and visible spectrum of streetlights using a digital lux meter and smartphone camera equipped with 500 lines/mm diffraction gratings. The collected data were analysed to assess how streetlight designs affect the environment, with a focus on comparing theoretical and measured lux and lumen values. The findings revealed that the installed streetlight bulbs contributed to light pollution, particularly through lux levels that exceeded standard limits by 60%, as well as the emission of potentially harmful wavelengths such as blue and violet light. These results offer valuable insights that can help shape better urban lighting designs. Additionally, the findings can assist local governments in balancing public safety, energy efficiency, and environmental protection in street lighting designs. Future studies should expand to other areas, such as Tawau and Semporna, where sea turtle populations are common. This would help protect these creatures from the adverse effects of artificial lighting on marine ecosystems. Finally, wavelength measurements in future research could be refined using a spectral light meter to enhance accuracy
Ergonomic Risk Assessment of Backpack Leaf Blower Operation: A Case Study of Outdoor Cleaning Staff in a Malaysian Polytechnic
Get PDFOutdoor cleaning tasks expose workers to ergonomic risks due to repetitive motions, awkward postures, and prolonged equipment handling. Poor working conditions pose significant detriments, leading to physical strain for employees and negative economic repercussions for employers. Despite these concerns, such risks remain understudied in Malaysia, prompting this study to investigate the ergonomic hazards associated with backpack leaf blower operation among cleaning staff at a Malaysia polytechnic. The research aims to assess musculoskeletal discomfort, identify ergonomic risks, and propose interventions to enhance worker safety and comfort. Five workers participated in the study, with data collected using the Ergonomic tools employed included the Body Map Questionnaire to assess discomfort, an Initial Ergonomics Risk Checklist to evaluate postures, repetitive motions, force exertion, and noise exposure, as well as task observations and noise measurements. Results showed that musculoskeletal discomfort was prevalent, with significant discomfort reported in the lower back, shoulders, and neck. The discomfort was linked to awkward postures, repetitive arm movements, and prolonged force exertion while operating 6 kg backpack blowers for extended periods. Noise exposure also exceeded permissible limits, indicating potential hearing risks. These findings highlight a lack of ergonomic research on Malaysia’s outdoor workforce and the need for targeted interventions. The study recommends advanced ergonomic assessments such as the Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA), along with preventive measures including ergonomically designed equipment, job rotation, and personal protective equipment like ear protection and anti-vibration gloves. The outcomes contribute to improving worker well-being and promoting compliance with occupational safety standards in the outdoor cleaning sector
Characterisation of Polyhydroxyalkanoates (PHA) Extracted from Palm Oil Mill Effluent Using Different Solvents
Get PDFPolyhydroxyalkanoates (PHA) represent a class of biodegradable polymers with immense potential for mitigating environmental issues associated with conventional plastics. Palm Oil Mill Effluent (POME), an abundant byproduct of the palm oil industry, serves as an economically viable source for PHA production. This study focuses on the characterisation of PHA extracted from POME using a variety of solvents and solvent mixtures. The solvents employed in this research include mixtures of acetone (AC) and ethyl acetate (EA) in the ratios of 75:25, 50:50, and 25:75. The choice of solvent during the extraction process significantly influences the yield and properties of the extracted PHA. This research employs a systematic approach to assess the impact of different solvents on PHA yield. The extraction process involves the collection of POME samples from local palm oil mills, followed by the isolation of PHA using solvents of varying polarities. The extracted PHA was characterised using UV-Vis spectroscopy to determine the efficacy and purity of each solvent and solvent mixture in PHA extraction. The UV-Vis spectral analysis revealed distinct absorption peaks corresponding to the presence of PHA. The extraction efficiency and purity of the PHA varied significantly with the choice of solvent and solvent mixture. Acetone exhibited a strong absorption peak, indicating a high efficiency in PHA extraction, while ethyl acetate showed moderate results. Results indicated that the solvent mixture of AC and EA in a 25:75 ratio yielded the highest purity of PHA, 86%, with a loss of 14%. The findings are anticipated to inform the optimisation of solvent selection, furthering the goal of utilising POME as a valuable resource for environmentally friendly PHA production
Development of a Portable LoRa-Based Data Logger System for Enhanced Flash Flood Monitoring in Remote Upstream Catchments of Sarawak
Get PDFIn Sarawak, flash floods are often triggered by intense rainfall over hilly and upland catchments, causing rapid runoff into major rivers and their tributaries. These events pose significant risks to downstream towns, particularly when they coincide with high tides. Although Automatic Weather Stations (AWS) provide essential environmental data for the National Flood Forecasting and Warning System (PRAB), their fixed locations result in limited coverage in remote tributaries. This creates spatial data gaps that reduce the accuracy of flood prediction and early warning. This project aimed to develop a low-cost, portable data logger system to complement existing AWS infrastructure by enabling real-time monitoring in remote upstream areas. The proposed system is equipped with a LoRa communication shield and a micro-SD card to allow efficient data transmission and storage while operating independently of internet access and the power grid. It also includes locally processed alerts, enabling immediate early warning in the surrounding area with the same data forwarded to the nearest AWS or server for further dissemination via PRAB. Sensor modules were calibrated to maintain accuracy within a 1% error margin. The system was validated through flood simulation tests and performance evaluation of the LoRa 915 MHz communication module, which demonstrated a strong linear correlation between transmission distance and received signal strength (RSSI). Preliminary analysis using SRTM-derived Digital Elevation Model (DEM) data and hydrological tools in QGIS supported strategic data logger placement. Long Banga was selected as a representative site due to its location in a flash flood-prone sub-catchment with limited AWS coverage. Overall, the proposed system enhances localised flood detection, supports PRAB data requirements, and cost-effective solution for strengthening early warning capabilities in remote river basins
