Abstract

Agro-industry is a sector that has quite diverse development potential, especially in the field of processing. One of them is processing fruit into fruit juice drinks. Nozy Juice is classified as an advanced MSME, but its competitive level is still lower than other agro-industry. This is because almost all of Nozy Juice's production activities are still done manually, giving rise to various risks that have an impact on decreasing the company's productivity level. To reduce this risk, a fuzzy-based House of Risk (HOR) approach is used which aims to identify the most critical risk agents. Then the risk mitigation design is carried out as an action plan. The essential risk of the 15 risk agents was a human error with an Aggregate Risk Potential (ARP) percentage of 24.275%. Furthermore, a risk mitigation design is carried out for 10 risk events. This is expected to minimize risks in the production process of packaged fruit juice drinks at Nozy Juice.

Abstract

Prevention of Covid-19 is important for research in order to reduce positive cases that occur in Indonesia. One of the popular research is using analytical method. The purpose of this study was to determine the relationship between work activity behavior, government and community regulations and social distancing as a mediator in preventing an increase in Covid-19 cases in West Java. This research method uses path analysis model. Social distancing variables directly have a positive and significant impact on preventing positive cases of Covid-19, meaning that with social distancing the spread of the Covid-19 virus can be reduced. The effect of social distancing on the prevention of positive cases of Covid-19 is 87% and the remaining 13% is due to the influence of other factors. Based on the four variables used as predictors of the prevention of Covid-19 cases, the social distance variable is the strongest variable that affects the prevention of positive cases of Covid-19 compared to the other three variables. Social distancing is very important to reduce the spread of Covid-19 cases. The implication of this research shows that awareness of people's behavior by keeping a distance is very important to prevent the Covid-19 virus.

Abstract

Horseshoe is used to avoid the failures of horse's hooves due to extreme impact and wear loads. The horse's hooves are repeatedly subjected to loadings during walking, trotting, running and jumping. In this research, we introduce a newly developed horseshoes made of polymeric composite materials. The horseshoes are placed inside the leather boot; it is a specially designed for horse. The process of making horseshoes and horse boots were discussed and the responses of the horse shoes as well as horses were analyzed. The horses were subjected to a series of testing, e.g., walking, trotting, and running. The result of the tests indicate that horseshoes and horse boots are quite strong, light, and safe to be used on horses. The response of horses shows that the horseshoe and boots are quite comfortable for them. This can be seen because there are no significant behavioral changes of the horse before and after wearing the boot. After being used to, it was shown that there is no damage or crack of the horseshoe. Therefore, it can be concluded that the composite horseshoe is safe and good to be used as horseshoe material.

Abstract

The COVID-19 pandemic has occurred throughout the world, and also in Indonesia. The government try to reduce the spread of COVID-19 by implementing various policies such as the large-scale social restriction (PSBB) policy, as well as other related policies. However, this policy has not been effective in view of the level of the spread of COVID-19 which has not decreased. Lack of public awareness is the cause of the spread of COVID-19 in Indonesia. For this reason, this study examines the effect of social support and social trust on the efficacy response to COVID-19 using the structural equation modeling (SEM) method. This factor was chosen because social support is an important aspect of the life of Indonesian society. This research was conducted on formal and informal workers, because workers are still required to have activities outside the home. The results show that social support and social trust are more influential on formal workers than informal workers. Strategy recommendations are compiled based on literature studies. After that, the weighting was done by using a relationship matrix. The results of the relationship matrix are seven prioritized strategies for formal workers, and three prioritized strategies for informal workers.

Abstract

Various companies want to improve product quality and process speed for customer satisfaction in the current era, including PT. X. Problems at PT. X is the number of defects that exceed the company's tolerance limit. The methodology used is a structured DMAIC method to identify the root causes of defects and resolve them. This study aimed to reduce defects in sportswear products caused by problems in the sewing process. The results showed that the problem in the sewing process was due to the process performance that still did not meet the standard process requirements, so the resulting output did not match the company's specifications. Therefore, it is necessary to design an alarm timer integrated with the sewing machine to minimize the frequency of defects in the sewing process. The design of the alarm timer uses the Reverse Engineering design method, which can minimize defects in the sewing process and increase the capability of the PT. X process.

Abstract

The purpose of this literature is to understand the application of macroergonomics in various fields. Macroergonomics is the study of work systems which include organizational structures (complexity, formalization, centralization, policies, and processes) with a socio-technical approach used to improve work systems. The method used is a thematic analysis of articles on the application of macroergonomics in various industries. Based on the results of the article review, the process of implementing macroergonomics is analysis, design, implementation, control, and evaluation. All review articles carry out macro ergonomics analysis and design within the scope of the work system as a whole but do not intervene in all factors/problems. The reviewed articles show that the intervention is carried out only on a few factors, where human and organizational factors are always involved. The application of macroergonomics can achieve many goals at once that are beneficial to organizations, workers, and even consumers. The highest frequency of macro ergonomics objectives in consecutive review articles was: quality, occupational health, safety, work existence, productivity, efficiency, and effectiveness.
