Manual activities of workers in palm oil factories cause pain complaints that can be resolved with an ergonomic program. However, the uncertainty of the success of the ergonomic program requires active involvement from workers. This study aims to discuss the role of workers’ perceptions towards the success of the ergonomic program intervention in palm oil mills. By referring to the theory of reasoned action and technology acceptance model, acceptance of workers to ergonomics programs are influenced by perceived usefulness, perceived ease of use, and perceived trust. All these research variables were analyzed simultaneously using Partial Least Squares Structural Equation Modeling (PLS-SEM) software, in which data were obtained from questionnaires given to 280 people working in 20 palm oil mills in North Sumatra Province. The sampling method used is simple random sampling and model estimation is performed using PLS regression algorithm and resampling bootstrapping method. The result shows that perceived usefulness has the biggest effect on the success of the ergonomic program, followed by perceived trust and perceived ease of use, which has a smaller effect. This study focuses on workers’ perception that needs to be considered for facing uncertain results in implementing an ergonomic program.

Prior studies suggest that differentiating strategy (DS) has an intervening impact on the relationship between entrepreneurial orientation (EO) and performance. However, they only examine the impacts based on each dimension of EO, provide a lack of theory underpinning why this strategy is the mediator, and focus on the manufacturing industry of an emerging market. Addressing these gaps, the purpose of this study draws from the contingency theory in strategic management to examine whether this strategy is the mediator in the context of Vietnam. Partial least square structural equation modeling used to assess the research model with data collected from 142 SMEs operating in Vietnam. The result indicates that DS fully has an intervening effect on the association between EO and SMEs' performance.

The advancement of sustainable competitiveness and its contribution to the sustainability of sustainable development are becoming increasingly important research topics in sustainability science. The main purpose of this study is to disseminate knowledge in the practice of entrepreneurship and to strengthen the theoretical foundation to support sound and appropriate decision making as well as to improve the performance of the business competitiveness. The main source of data material in this paper is the primary micro fundamental survey with path analysis model. The result of this study shows that technological innovation not only produces new products but can also be the best way to achieve advancement. New Product Development (NPD) is the output of technological innovation, and the best way that must be developed as a strong foundation for decision makers to achieve sustainable competitiveness progress is the new product development and institutional integration. If productivity and economic growth are the main keys to success in achieving sustainable competitiveness, the NPD and institutional integration is the main determinant of the progress of sustainable competitiveness. The conclusion of this study is that productivity and economic growth is not enough to be the main key of the strength of competitiveness, but it also requires collaboration from various fundamental factors and the NPD and institutional integration as a driving force, the best way, and the main determinant of the achievement of the performance progress of sustainable development competitiveness.

The culinary business sector is the choice of the COVID-19 pandemic; Women entrepreneurs and the informal sector are looking for a foothold in the COVID-19 pandemic, which will lead women to develop creative businesses. This study examines the role of supply chain management in mediating the role of social capital and marketing performance, innovation on marketing performance, and the mediating role of sharing knowledge on marketing performance among women entrepreneurs in Bali. Purposive sampling is used in the sampling technique, with 229 samples used, the Structural Equation Modeling (SEM-PLS) analysis technique with SmartPLS for application processing. The results showed that in order to increase sales, retain customers and reach a high market, good quality products and services owned by the supply chain, from social networking relationships and knowledge sharing, are needed. However, the increase in marketing performance cannot increase even though women entrepreneurs have strong relationships.

This research was conducted to examine the extent to which market uncertainty can encourage market players, especially SMEs, to exploit innovation and environmentally friendly orientation to improve their performance. From a supply chain perspective, market uncertainty, which in this study is proxied by the Covid-19 pandemic, has great potential to reduce performance and disrupt production and distribution lines as well as consumer demand. This encourages affected SMEs, such as SMEs that focus on providing tourism products, such as fashion and merchandise, to maintain their performance with product innovation, and minimize the use of non-environmentally friendly products. The object of research is Small and Medium Enterprise (SME) producing tourism souvenirs in Yogyakarta, Indonesia. Using the analysis technique of Structural Equation Modeling (SEM) with 150 respondents, the findings indicate that market uncertainty serves as a catalyst for SMEs to maintain performance through marketing innovation and product reorientation. Specifically, the results show that there is a positive and significant influence between innovation and green orientation on SME performance, and the mediating effect of market uncertainty to increase marketing innovation and environmentally friendly orientation. These findings theoretically contribute to explaining the relationship between supply chain management in the context of market uncertainty. In practical terms, this study confirms the need for support by stakeholders to support limited domestic tourism, according to health protocols, as well as digitalization of marketing for tourism SMEs.

The aim of this study was focused on cooperation in the fisheries supply chain. Specifically, the study of the factors affecting the benefits of cooperation and the relationship between the factors.

Managing water resources is one of the most challenging problems in today’s world. There is an immense change in climate change, population growth, and environment, thereby increasing pressures on water resources. Due to future uncertainty and availability of resources, many priorities should be taken into account in the drinking-water system such as environmental impacts, distribution costs and fixed costs. This paper proposes a deterministic mixed-integer linear programming (MILP) model for planning and designing a water supply chain network in order to optimize multi-objective problems. The model considers costs which include fixed and variable costs, in addition, it considers sustainability in terms of environmental viewpoint. The applicability of the model is appraised through a case study whose data gathered from related articles and water and waste company reports in Iran, which consists of five candidate reservoir nodes and four dam nodes besides eleven candidate locations for treatment plants. Thereafter, the proposed model has been coded in GAMS® optimization software. The model could be an expedient tool in order to manage urban water supply chains in a cost-effective and sustainable manner to satisfy water demand at every time period.
