Judul: Analisis Beban Kerja Stakeholders Dalam Aktivitas Rantai Pasok Komoditas Kentang Di Berastagi, Sumatera Utara
Abstrak: Kecamatan Berastagi merupakan salah satu daerah penghasil kentang (Solanum tuberosum L) tipe Granola. Tujuan dari penelitian ini adalah : (1) Menganalisis waktu kerja dalam rantai pasok stakeholders pada komoditas kentang berdasarkan analisis beban kerja melalui perhitungan Full Time Equivalent (FTE), (2) Menganalisis peluang efektivitas dan efisiensi aktivitas rantai pasok stakeholders melalui business process mapping berdasarkan kondisi eksisting dalam rangka meningkatkan daya saing petani dari segi harga dan kualitas, (3) Menganalisis distribusi nilai tambah yang didapat oleh masing-masing stakeholders berdasarkan aktifitas yang dilakukan melalui analisis nilai tambah Hayami. Penelitian dilakukan di Desa Gurusinga, Kecamatan Berastagi, Sumatera Utara. Pengumpulan data diperoleh melalui wawancara, observasi, studi literatur beserta internet. Hasil FTE menunjukkan bahwa waktu kerja yang digunakan masih belum optimal dikarenakan metode pertanian yang konvensional. Berdasarkan business process mapping, kondisi eksisting aktivitas rantai pasok kentang di Kecamatan Berastagi masih belum efektif dan efisien dikarenakan penggunaan bibit yang belum terstandarisasi dan kurangnya pemahaman petani tentang pentingnya kontrak bisnis. Dari perhitungan distribusi nilai tambah didapat nilai tambah stakeholders yang tidak sesuai dengan banyaknya aktifitas yang dilakukan. Hal ini dapat diatasi dengan business process reengineering melalui training dan penyuluhan trust building, improvement, budidaya organik dan relationship building.

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.
