Abstrak: The objective of the research were to examine the workload for several age levels of workers, to observe the tools and equipments utilization effect to fatigue, and also to recommend an optimal work system that related with tools/equipment utilization and work scheduling through ergonomic approach of sweet potato processing. The subjects employed in this research were 12 employees that divided based on age level into young, middle, and old age. The results of this research showed that the highest energy consumption when doing a work is on subject in old age group. Therefore, the morning shift is preferable to be taken by the old age workers with assistance from young and middle age workers, whereas afternoon and night shift were preferable for middle and young age. The highest productivity was coming from the middle age group that was constant in every work shift. The questionnaire results indicated that the workload of subjects on medium workload category, but in case of working equipment, subjects were situated in very uncomfortable category for using working tools and equipment, so the repairments based on anthropometric dimensions are required in order to fit the workers to the task.

Judul: Durability of Specific Immunoglobulin (Ig) Y Againts Influenza and Covid-19 in Sunscreen
Abstrak: The benefit of specific immunoglobulin Y (Ig Y) as an active ingredient in personal care products such as sunscreen has not been properly studied. Our study aims to evaluate the reliability of specific IgY against influenza and the COVID-19 virus in a sample sunscreen product. Specific IgY influenza and COVID-19 viruses were inserted in the sample sunscreen at two concentrations of 0.1% and 0.25%. Three treatments were observed: control (C) sunscreen without IgY, treatment 1 (T1) sunscreen with 0.1% IgY, and treatment 2 (T2) sunscreen with 0.25% IgY. Organoleptic observations were carried out to monitor changes in aroma, color, and texture, and sunscreen sampling was done every week for 6 weeks. The durability of IgY was evaluated using an enzyme-linked immunosorbent assay (ELISA) and a neutralization assay. Organoleptic observation from weeks 1 to 6 showed consistency in its aroma, color, and texture. Enzyme-linked immunosorbent assay and neutralization assay (NA) results of the T1 and T2 groups showed negative results except for sample T1 at week 5, which showed a positive result in the Influenza A ELISA. Based on the results, it seems that IgY concentrations of 0.1% or 0.25% were not optimal. However, this negative result might be due to low concentration of the IgY and the presence of beeswax, which inhibits IgY and causes it to dissolve in distilled water, thus preventing it from being detected in the assay.
