Abstrak: The increase of import volume and the decrease of export volume of vegetables require the efforts to improve the competitiveness of local vegetable products. Potato is the core of highland vegetable commodities in national and regional areas that potential to be developed. One of the potatoes production centers in Central Java is Banjarnegara regency. The purpose of this study are to formulate strategy and Key Performance Indicators (KPIs) that will improve the competitiveness of potato in Banjarnegara. The source of primary data obtained from interviews and secondary data obtained from study of literature. Data have been analyzed by descriptive analysis, TOWS analysis, The House Model, and Pairwise Comparison. The results of this study indicate that the strategies that become the priorities to improve the competitiveness of potato in Banjarnegara are the provision of cooperation in indicator of the number of farmers who distribute their products in cooperative, quality improvement of potatoes production in indicator of increasing the number of certified seed potatoes that meet farmers needs, and increased protection against farmers in indicator of regulation and government policy.

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.
