Background: Workers in utility industries are exposed to occupational accidents due to inadequate safety management systems. Accordingly, it is necessary to characterize and compare the available literature on indicators used in safety management practices in the utility industries. Methods: The systematic literature review was based on the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement. This study considered 25 related studies from Web of Science and Scopus databases. Results: Further review of these articles resulted in three mains performance indicators; namely, driven leading indicators, observant leading indicators, and lagging indicators consisting of 15 sub-indicators. Conclusions: Future studies should consider researching a more comprehensive range of utility industries, measuring subjective and objective indicators, integrating risk management into safety management practices, and validating the influence of leading indicators on safety outcomes. Further, researchers recommend including accidents, fatalities, lost time injuries, and near misses in safety outcomes.
The zero-accident vision has sparked debate in the fields of occupational safety and health. While many organizations and policymakers have successfully implemented the zero-accident vision, numerous notable occupational safety and health scholars from various backgrounds argue against its use and success in theory and practice. This article aimed to analyze the existing literature on the variables impacting an organization’s zero-accident vision. A systematic review of the Scopus and Web of Science databases revealed 25 related studies using the PRISMA statement (preferred reporting items for systematic reviews and meta-analyses) review method. Following a thorough review of these articles, seven main themes emerged: the occupational safety and health management system, organizational leadership, safety culture, training, communication, risk, and legislation. These seven themes resulted in a total of 28 sub-themes. Several recommendations are emphasized, including the use of a specific and standard systematic review method to guide research synthesis in the frame of reference of variables impacting the organization’s zero-accident vision and to practice complementary searching techniques, such as citation tracking, reference searching, snowballing, and contacting experts.
Title: Safety competencies: A systematic literature review. Background: Safety competency is believed to be a pillar of an organization’s safety culture and one of the safety climate dimensions. Safety competencies can be a vital point to controlling and maintaining the sustainability of safety and health in a society and organization. The sustainability of the industries’ and society’s safety relationship can be driven by the controlled hierarchy in the society and the competencies of its members. Failure to identify social sustainability indicators such as a leading competency in safety will cause a failure in the safety development program. Hence, a systematic literature review of published studies is essential for easing the dissemination of useful research findings and gaining access to future trends in safety competencies research. The review aimed to identify studies about safety competency and identified the basic safety competencies for the workforce to maintain a sustainable safety climate. Methods: This review provided a five-step approach guided by The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 statement and published systematic review framework. The studies from the past 20 years were retrieved from electronic databases such as Scopus, Science Direct, and Web of Science. The review only involved article papers, research papers, and review papers which are written in English. The quality of the review was assessed using a standard PRISMA 2020 checklist. This review is registered on the International Platform of Registered Systematic Review and Meta-Analysis Protocols (INPLASY) with registration number INPLASY202230246 and DOI number 10.37766/inplasy2022.3.0146. Findings: The unbiased and wide review produces a new, feasible alternative to a social sustainability safety index. The number of studies on safety competencies study has expanded in recent years which shows the importance of the item to sustain the safety climate. This review suggests teamwork, communication skills, and a foundation of safety knowledge as the basic safety competencies for workers based on the competencies being most discussed. The review process suggests the possibility of future research regarding safety competencies after a catastrophic event such as the COVID-19 pandemic and sustainability of industrial safety regarding human-machine integration through 4.0 Industrial Revolution era.
Analyze the decrease of the concentration of heavy metals Hg2+on entisols polluted by mercury due to the provision of humic acid and fulvic acid of Tithonia diversifolia. There are nine levels: With no humic acid and fulvic acid treatments (FVA0); 50 ml of fulvic acid per kg-1soil (FA50), 75 ml (FA75),100 ml (FA100), 125 ml (FA125), 50 ml of humic acid per kg- 1soil (HA50), 75 ml (HA75), 100 ml (HA100), and 125 ml (HA125). The concentration of Hg2+in entisol was measured by means of Mercury Analyzer (AAS). The results revealed that regarding mercury content in the soil, fulvic acid had a better effect on the change of Hg- chelate compared with humic acid. Fulvic acid was able to increase Hg-chelate up to 96.58%, whereas humic acid by 83.06% at a dose of 125 ml kg-1entisols for 40 days of incubation.
This research aims to assess the rate of agricultural land conversion, analyze factors affectagricultural land conversion, and analyze the impact of land conversion on rice production in Sigi District. Data analysis used is analysis of conversion rate, logistic regression analysis, and analysis of impact production. Result obtained Conversion of paddy field that happened in Sigi District from year 2009 until year 2016 which is about 20,75% or 4,499 Ha. with average value of depreciation every year equal to 2,96% or equal to 645,57 Ha.Based on the results of logistic regression analysis obtained from 7 independent variables, only 3 variables that significantly affect the land conversion that occurred. The influential variables are land area, land selling price, and number of family dependents with Prob value. <α (10%). Variables that have no effect on land conversion are length of stay, duration of farming, yield, and selling price of paddy. Based on the results of production impact analysis, obtained the lost production capacity of 39,719.81 tons of dry milled grain or about 4,467.97 tons of dry milled grain per year.
