“…Based on the analysis and type of data, this study was included in the combined study because this study used quantitative and qualitative data. While the observed objects of research are machine and equipment, physical work environment conditions, layouts, work methods, organization policy, and workers within the scope of rubber processing plants [5,6,7,8]. There were 25 samples in total sampling technique used in this research and data collected through observation, open and closed questionnaire to the respondent and measuring heat felt by the worker using Heat Stress Index.…”

“…According to Henrik and Kleiner, Macro-Ergonomics is an approach that studies how to optimize the organization and design of the work system by considering human, technological, and environmental variables, as well as interactions between these variables and ensuring the work system in harmony. [2,5,6,7,8] Moist work environment, heat, dust, and the lack of air circulation in the production section make the operator uncomfortable for work. Mudji state that the physical work environment affects health and indirectly influences productivity and occupational safety [9,10].…”

Abstract. This study was conducted at an RSS (Ribbed Smoked Sheets) manufacturer in North Sumatra. In the preliminary observation, manufacturer encountered some problems such as machine breakdown (43 times in 2016 with 98 hours of downtime), scattered equipment, high temperature at all workstations, odor, disobedience against company regulations, and delay in product delivery. The aim of this research is to improve work design with variables such as machinery and equipment, physical environment condition, layout, working method, and organizational regulation, and worker with macro-ergonomic technique. There were 25 samples in total sampling technique used in this research and data collected through observation, open and closed questionnaire distribution to the respondent and measuring heat stress index felt by the worker. The results of the analysis showed two work design variables that had the highest severity, they are improvements to machinery and equipment variables by doing preventive maintenance while improving working environment conditions by installing turbine ventilator.

“…In the modeling of supply chain resilience, simulation [4,26,36,42,82,94] and mathematical models [95] are developed to manage or mitigate disruptions through optimization. Simulation allows one to represent the behavior of the system in the event of a disruption in real-time.…”

“…Researchers for supply chain resilience optimization have also deployed mathematical models. For instance, [95] used a mathematical model to represent the operation, transportation, environmental and delay costs reduction caused by disruptions in the natural gas supply chain. In a more recent work [28], optimization was introduced to an interdependent power-water network to achieve a resilient supply chain using a mathematical modeling approach.…”

The concept of supply chain resilience continues to attract both industry and research experts in the field of energy. These stakeholders continue to tackle disruptions to supply chain systems through the introduction of strategy options for resilience. A better understanding of broader dimensions of potential disruptions to supply chains caused by uncertainties has become eminent, especially as currently experienced during the global COVID-19 pandemic. The effects of the outbreak in disrupting supply chains in the energy sector will, in the next decade, continue to be a likely concern for industry and research stakeholders. Balancing the increasing need for energy security to meet the continuous growth in energy demand through shortage reduction and increased uptime using optimization is the core of this research. This review paper provides an insight into recent studies in the field of natural gas supply chain resilience as a major player in the energy mix, and the continued disruption and subsequent shutdowns of plant nodes, which results in emission loss to the environment. This paper is motivated by the disparity between demand and supply triggered by the disruption of supply chain networks. This paper referenced scientific work on supply chain resilience of biomass, water, power systems, and natural gas. Findings show that existing studies favor fewer system-based strategies in optimizing for resilience. This review concludes that optimization is a useful tool to continuously achieve resilience in supply chain production, storage, and transportation activities.

“…Direct activities are defined by discipline or scope, whereas indirect activities are determined by the construction phase's planning and execution stages (Suppramaniam & Ismail, 2019). According to Aldhaheri et al, fabricators manage the way they acquire materials and manpower to optimise project value while profiting from Engineering, Procurement, and Construction (EPC) project activities (Azadeh et al, 2016). Lack of project management and cost monitoring of resource allocation currently during fabrication operations which contractor site management and financial management are considered separately.…”

Every project involved in oil and gas fabrication erected onshore usually experiences cost overruns. This cost overrun is closely related to the use of machines, manpower, methods, money, and materials (5M) in order in a project where all these resources require a good financial cycle. However, these cost overruns often occur due to improper management planned resource allocation. Therefore, this study was aimed to examine the issue on mismanaged resource allocation affected cost overruns specifically in oil and gas fabrication projects as a preliminary study. Semi structured interviews with ten (10) qualified specialists in the Engineering Procurement Construction (EPC) projects from the Oil and Gas industry were conducted for strengthening the assistance of the cost overruns issues. In accordance with the results of the expert's interview, there are several factors that contribute to project cost overruns, including inconsistent resource allocation to project activities, financial constraints, a lack of suitable resources, and difficulties obtaining resources that are compatible with project objectives. By using the ATLAS-ti to study the networks, it was revealed that money had a greater impact on the allocated resources and the issue of budget or money allocation that does not meet project requirements is a major issue which led to cost overruns. In conclusion, safety, time, quality, and cost are the key considerations for determining the success of the project performance for all projects that are managed by project management in conjunction with numerous phases that are involved from the project's beginning until it is successfully completed in accordance with contractual agreement. Cost or money is one of the most important aspects to pay attention on.
