Judul: Kajian Kawasan Sapi Potong di Kabupaten Raja Ampat  Provinsi Papua Barat
Abstrak: Penelitian ini bertujuan untuk mengkaji dan merumuskan model kawasan sapi potong berbasis sumberdaya ternak di Kabupaten Raja Ampat. Pelaksanaan penelitian dilakukan di Kampung Sakabu, Kalobo dan Waijan Distrik Salawati Utara, selama Agustus 2008 – Mei 2009. Pengumpulan data menggunakan metode survei terhadap 218 orang peternak responden dan 314 ekor sampel ternak. Data yang diperoleh terdiri atas : (1) data primer, yaitu data hasil pengamatan dan wawancara dengan responden, meliputi ; karakteristik produksi ternak sapi potong, karakteristik peternak, dan pola manajemen produksi sapi potong yang ada; (2) data sekunder, meliputi; karakteristik wilayah yang terdiri dari iklim dan topografi, sistem penggunaan lahan, karakteristik kelembagaan yang ada dan kebijakan pemerintah daerah dalam pengembangan peternakan. Data karakteristik peternak dan pola managemen dianalisis secara deskriptif, produktivitas sapi potong dievaluasi dan diukur berdasarkan estimasi bobot badan. Perbandingan skor nilai pengetahuan, motivasi dan partisipasi peternak dalam pengembangan sapi potong menggunakan metode uji Mann-Whitney. Pengelompokan kesamaan potensi wilayah untuk kawasan sapi potong menggunakan analisis gerombol (Cluster Analisis). Penentuan model kawasan sapi potong menggunakan kriteria dan indikator komponen kawasan meliputi; (1) lahan; (2) kapasitas peningkatan populasi ternak ruminansia (KPPTR) efektif dalam satuan ternak (ST); (3) ternak; (4) teknis budidaya ; (5) peternak; (6) tenaga pendamping; (7) fasilitas dan (8) kelembagaan. Keseluruhan hasil analisis digunakan untuk menyusun strategi pengembangan kawasan, menggunakan analisis SWOT dengan metode tabel IFAS dan EFAS.

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.
