The Importance of Ecological and Spiritual Approaches in Chemical Engineering towards Practical Conception of Sustainable Development
The issues in sustainable development are of two kinds; the interdependent of three principle pillars of sustainable development-environment, social, and economy development and human spiritual development. The main objective of this paper is to discuss on the importance of spiritual enhancement and ecological approach in chemical engineering to develop a notion of conception for sustainability. We elaborate and discuss contemporary Islamic principle named “Jurisprudence of Priorities” ( Fiqh Al-Aulawiyyat) and what it suggests for sustainability and concurrently delineate the need for ecological approach in chemical engineering. The study was conducted based on available published articles from books, handbooks, journals, and other online reliable sources related to environment and sustainability. The study concentrates on both Islamic jurisprudence principle in conserving the nature and ecological approach in chemical engineering. The examples presented in this article provide new information on the importance of spiritual development and ecological considerate in chemical engineering towards successful sustainable development. This study is perhaps one of the first to address the incorporation of spiritual enhancement (Islamic principle) and ecological approach in chemical engineering to create environmental awareness among world community
Design and Calibration of Pinch Force Measurement Using Strain Gauge for Post-Stroke Patients
Two fingers strength is an indicative measurement of pinch impairment. Conventionally, Fugl Meyer Upper Extremity Assessment (FMA-UE) is the primary standard to measure pinch strength of post-stroke survivors. In literature, the evaluation method performed by the therapist is subjective and exposed to inter-rater and intra-rater reliabilities. Recently, force-sensing resistors were implemented to measure two fingers force, but these sensors are subjected to nonlinearity, high hysteresis, and voltage drift. This paper presents a design of pinch force measurement based on the strain gauge. The pinch sensor was calibrated within a range of between 0 N to 50 N over a pinching length of 20 mm with a linearity error of 0.0123% and hysteresis of 0.513% during the loading and unloading process. The voltage drift has an average of 0.24% over 20 minutes. The pinch force measurement system reveals an objective pinch force measurements in evaluating the rehabilitation progress of post-stroke patients
Safety culture awareness and practices in the malaysian mining industry : A preliminary study
Presently, safety culture is receiving attention for the prevention of mining disaster or accidents. The mining industry in Malaysia has been around for 200 years and fortunately, to date, there is no large-scale mining disaster that has occurred in Malaysia. However, that led to a lack of study on the safety culture in Malaysian mining industry. The study aims at exploring the current status of safety culture awareness and practices in Malaysian mining industry. A qualitative, open-ended interview session was conducted in April 2021 via the online Google Meet platform. Six mining experts had agreed and volunteered to be involved in the interview session. Three themes were created: (1) Significance of safety culture in mining; (2) Factors that make up the safety culture in mining industry; and (3) Adopting safety culture in mining industry. Three themes and eight sub- themes were validated by the mining expert interviewers. In conclusion, the current status of safety culture awareness and practices in mining industry is very low. It was observed that there was a huge gap between small-scale and large-scale mining operation in Malaysia. For small-scale mining operation, it was below 50%, where one of expert claimed it to be approximately 30%. It is recommended that the top management of mining companies have their mindset changed, not only focusing on the profit but to strengthen the safety aspects as well. A good safety culture will increase the workers and operational productivities and prevent mining accident or disaster in Malaysia in the near future
Investigate the factors affecting safety culture in the Malaysian mining industry
Nowadays, safety culture is critical in preventing near-misses, accidents, and disasters. It has three dimensions: psychological, situational, and behavioural. To the best of the author’s knowledge, lack of research has been done on psychological and behaviour safety culture in the Malaysian mining industry. The objective of the study is to investigate the factors affecting psychological and behaviour safety culture in the Malaysian mining in- dustry. A two-round online Delphi method was performed among mining experts. The Delphi Experts (n = 21) with extensive experience in mining operations volunteered in this study. The Delphi I (open ended interview) and Delphi II (questionnaire survey) were completed by 100% (n = 21/21) and 87.5% (n = 18/21) of the experts, respectively. Thematic analysis was used to analyse the Delphi I and generate five and nine themes for psychological, situational and behaviour factors. For psychological safety culture, the Delphi II resulted median, IQD and percentage distribution analysis with 83.3%, 83.3% with the IQD cut-off (IQD ≤1) and 64.81% respectively. For situational, safety culture, the consensus was achieved with median, IQD and total percentage distribution analysis with 94.4%, 61.1% and 73.15%, respectively For behavioural safety culture, the consensus was achieved with median, IQD and total percentage distribution analysis with 94.4%, 66.7% and 73.6%, respectively. To conclude, the Delphi analysis revealed that experts agreed and consensuses were achieved on five, ten and nine factors that have major impacts on psychological, situational and behavioural safety culture in the Malaysian mining industry
Does Human Factor Contribute to Mining Accidents? A Systematic Literature Review Approach
Human factor always has been debated as the key factor contributes to industrial accidents such as manufacturing, construction and many more. However, there are lack of studies globally within this research to review and prove the human factor is a primary cause of accidents at mining industry. The objective of this systematic literature review (SLR) study is to investigate the dominant factor contributes to mining accidents by applying a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. Three main themes and fifteen subthemes have been developed based on 25 selected articles from Scopus database. The findings showed the organizational factor is the most dominant contributor to mining accidents (53%) followed by human factor (27%) and situational factor (20%). In conclusion, this finding hopefully could facilitate mine owners to improve organizational safety concern and provide a healthy safety culture in reducing mining accidents in future
The effect of storage conditions on ethanol content of kombucha tea
Ethanol is one of the alcohol compounds commonly found in food and beverages. Some of the food and beverage products sold in the market contain ethanol. In accordance with that, the objective of this research was to analyse the ethanol content of kombucha tea which is stored at a certain duration and temperature. The research experiment used commercial and homemade kombucha teas. The test was performed at 2 contact temperatures, 8°C (chiller) and 28°C (room temperature) for a duration of 4 weeks. Each sample was analysed for ethanol content, every 1 week using a gas chromatograph coupled with a single quadrupole mass spectrometer (GC-FID). The results demonstrate that storage temperature significantly influences ethanol production, with higher temperatures yielding elevated ethanol content. The ethanol content of commercial kombucha tea stored for 28 days at 28°C was the highest ethanol content (3.43±0.06% ABV). The lowest ethanol content was found in kombucha green tea (1.55±0.11% ABV) which was kept in the chiller (8°C) for the duration of 28 days. It was found that storage temperature and duration play important roles in the concentration of ethanol content. These findings provide producers and regulators with valuable insights for optimising storage practises, promoting halal compliance, and ensuring food safety while preserving fermented beverage’s quality and flavour
Does expert judgement is important in mining industry?: A systematic literature review
The Delphi technique is used to achieve consensus from a panel of experts on particular issues by several series or rounds. Previous scholars widely used Delphi in social science studies, business, healthcare, education and many more. However, there is a lack of systematic review on the contribution of Delphi in the engineering and technology field of research. Thus, the aims of this systematic literature review (SLR) are to investigate the contribution of Delphi in solving problems for the past 11 years in the mining industry and to understand the future outlook of Delphi in the Malaysian mining industry. By applying the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), 37 selected papers were identified with three main themes and 24 subthemes created using thematic analysis. Based on the findings, the most highlighted contribution of Delphi came from Theme 3: Delphi’s derivatives (50.0%), followed by Theme 1: Mine lifecycle (12.5%), and Theme 2: Analysis of Delphi (37.5 %). In conclusion, an SLR could hopefully increase awareness among mining players to use Delphi in solving their problems which cannot be solved by machinery or tools in achieving a consensus among experts
Aqueous phase reforming of sorbitol over sonosynthesized ca-doped ni supported on al2o3 and tio2 for production of value added chemicals
Production of value added chemicals derived from renewable carbohydrate such as sorbitol through the aqueous phase reforming is a promising technology. Aqueous phase reforming for industrial without highly effective and efficient catalyst in term of its operational lifetime and catalytic activity. Supported nickel catalyst has been identified have good selectivity of alcohols for aqueous phase reforming of sorbitol, and support such as Al2O3 and TiO2 has been identified as support which has good surface area and active sites. In this work, the effect of introducing the varying percentage of Ca (0%, 0.5%, 3% and 5%) as promoter onto 10% Ni supported on two potential catalyst support, TiO2 and Al2O3 have been investigated. The catalysts are prepared via the sonochemical method, where the catalysts are synthesized under ultrasonic irradiation for 45 minutes using ultrasonic probe at 90W using methods by Abdollahifar, et al. [1], where sonochemical method has discovered to enhance the dispersion of particles, improve surface area and increase the performance. The sonosynthesized catalysts were then subjected for characterization by using Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), Xray Powder Diffractometer (XRD
