Abstract

Many MSMEs in Indonesia have used e-business including, websites, social media, e-commerce, and Enterprise Requirement Planning (ERP). The aspects that need to be considered include resource management, finance, procurement, logistics, to operational activities. In addition, the challenges that must be faced by MSMEs, in external conditions, must reduce the physical distance to cope with the spread of Covid-19. Due to the outbreak, MSMEs have been compelled to employ alternative methods that must be created and implemented to keep business processes functioning. Therefore, what factors can affect the acceptance of technology that is perceived by MSME owners to adjust their business needs. This research aims to modify TAM for e-business users, especially in MSMEs, to analyze the factors affecting the technology adoption process. The research method used is to build models and indicators from previous studies. However, as discussed in model development, three external variables were added: perceived cost, perceived risk, and facilitating conditions. The next stage is to conduct empirical research using a google form for MSME owners. Based on this framework, we propose a model for research propositions and contributions to scientific studies.

Abstract

There is a concern to use masks during physical activities when exercising and working. Wearing masks during physical activity will pose a risk to physiological changes in the body and human heat strain by the principle of a mask can block the respiratory tract. This study aims to determine how much the human physiological changes quantitatively and qualitatively when using different types of medical masks, cloths and N95. There were 10 respondents as a sample of this study. The results obtained show that the different types of masks to the physiological response of the human body, cloth masks can affect the physiological changes the highest compared to medical masks and N95. The subjective response in the form of thermal comfort, mask sensation, and thermal sensation shows that of the 3 types of masks, the N95 mask is the mask that is the most uncomfortable when worn. The recommendations of the 3 types of masks are medical masks because they affect the slightest increase in the risk of heat stress while the cloth masks have the highest increase in tympanic temperature and Physiological Strain Index.

Abstract

The Sri Tanjung Cracker Company is an MSME that produces fish crackers. Currently, the Sri Tanjung cracker company lacks structured risk management, particularly in supply chain activities One of the known risks is that companies run out of raw materials, suppliers who ship late, and defective products. The goal of this study was to identify risks and develop appropriate preventive measures to reduce risks in the fish cracker production supply chain. This study maps supply chain operations using the SCOR model then uses the HOR method to classify risks and related mitigation strategies using Pareto diagrams and a probability impact matrix model. The results showed that the HOR phase 1 model comprises 60 risk events, 35 risk agents, and 7 priority risk agents for HOR phase 2 computation. HOR phase 2 shows 4 mitigation strategies that need to be addressed first. To conduct further research, if the suggested action is in the form of preventive action, it is required to quantify the impact of risk reduction and can add variables in the review of risk events, risk agents, and preventive measures to identify supply chain activities at the Sri Tanjung Fish Cracker Company.
