Judul: Arahan dan strategi pengembangan kawasan perdesaan dengan pendekatan agropolitan di Kabupaten Blitar
Abstrak: Kabupaten Blitar merupakan salah satu kabupaten yang terletak di Provinsi Jawa Timur dengan wilayah administrasi meliputi 22 kecamatan, 220 desa, dan 28 kelurahan. Melihat kondisi tersebut maka dapat diartikan bahwa mayoritas kawasan di wilayah Kabupaten Blitar adalah kawasan perdesaan. Belum optimalnya pembangunan di tingkat perdesaan menjadikan sebagian besar masyarakat lebih memilih untuk bermigrasi ke kota yang lebih besar atau bahkan ke luar negeri. Menurut Rustiardi, et al. (2005), fenomena migrasi adalah bentuk respon dari masyarakat karena adanya perbedaan ekspektasi dalam meningkatkan kesejahteraan dirinya. Dengan kata lain, migrasi desa-kota akan terus berlangsung sepanjang ada kesenjangan antara desa-kota. Menurut data podes 2008, jumlah penduduk Kabupaten Blitar yang berprofesi sebagai Tenaga Kerja Indonesia (TKI) ke luar negeri mencapai 28 430 jiwa. Salah satu cara dalam menanggulangi permasalahan kesenjangan antara desa-kota adalah dengan dilakukan kajian model pengembangan wilayah dengan pendekatan agropolitan. Agropolitan menjadi relevan dengan wilayah perdesaan karena pada umumnya sektor pertanian dan pengelolaan sumberdaya alam memang menjadi mata pencaharian utama dari sebagian besar masyarakat perdesaan. Untuk mengembangkan agropolitan diperlukan kajian terkait aspek ekonomi, aspek sosial, aspek wilayah, serta aspek kebijakan daerah. Selanjutnya dari semua kajian tersebut disusun strategi pengembangannya. Harapannya dengan memperhatikan kajian tersebut dapat memberikan hasil pembangunan yang berimbang serta memperhatikan karakteristik wilayah. Tujuan penelitian ini adalah: (1) mengidentifikasi hierarki wilayah dalam mendukung pengembangan agropolitan di Kabupaten Blitar; (2) mengidentifikasi tipologi wilayah masing-masing kecamatan beserta komoditas unggulan yang dapat dikembangkan dalam mendukung pengembangan agropolitan Kabupaten Blitar; (3) mengkaji arahan lokasi pusat pengembangan masing-masing cluster; (4) merumuskan arahan dan strategi pengembangan kawasan perdesaan dengan pendekatan agropolitan di Kabupaten Blitar.

Judul: Direction and strategy of rural area development using agropolitan approach in Blitar regency
Abstrak: One of the ways to solve the problem between the urban and rural gaps was applying the assessment model of regional development by using agropolitan approach. This approach became relevant to rural areas because agriculture sector and natural resource management had become the main livelihood of most rural communities. The aims of this study were: 1). to identify the typology of subdistricts in Blitar regency; 2). to analyze the prime agriculture commodities; 3). to determine the regional development center; 4). to formulate the direction and regional development strategy. The data analysis used in this study were Cluster Analysis, LQ and Shift Share, P-Median and A’WOT. The results showed that the typology of sub-districts in Blitar regency could be divided in three clusters e.g.: Cluster 1 with the development centre in Sanankulon sub-district was the paddy rice producing areas, Cluster 2 with the development centre in Wlingi sub-district was the plantation commodities areas and Cluster 3 with the development centre in Panggungrejo sub-district was the dry land farming areas. The direction and strategy development of those three clusters were increasing the productivity, cooperating with private sectors, training and disseminating, and supporting the farmers.

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.
