Judul: Perencanaan Lanskap Percontohan untuk Kawasan Rumah Pangan L􀀺stari (KRPL) di Pangalengan Jawa Barat
Abstrak: The increasing of population is the point of food security. This factor has caused decreasing in agricultural production land and farmer economic level. As long as food is a basic requirement for human life, people have to use their land for food production. KRPL is a sustainable food housing area program that propose by Badan Litbang Kementrian Pertanian (Balitbangtan) became one of potential way to utilize farmyard and land surround house area for food production. Rural area have a good potential for food subsistence, especially for integrated farming. Landscpae planning of KRPL will be functional space for food production in rural area. This study was aimed to make landscape planning of sustainable food housing area at Pangalengan. This study will use the survei method of qualitative descriptive and quantitative descriptive with planning process following Gold (1980) they are preparation, inventory, analysis, synthesis, and landscape planning stages. The descriptive and space analysis were used to determine the suitability of the spaceaccording to Balitbangtan. The planning products are; the main area with 13.55%, the supporting area with 4.14%, and the conservation area with 82.31% from total area.

Judul: Identifikasi lahan potensial untuk mendukung usulan perencanaan lahan pertanian pangan berkelanjutan
Abstrak: The passing of Law 41, 2009 on the Protection of Sustainable Food Farming Land (PSFFL) is expected to control the pace of agricultural land use change in particular fields. This law is still new so that many of its implementation have not been done, including the planning and establishment of regions, prime land and reserve land. West Java Province is the province's second-largest contributor to the national rice with the support of a potential wetland. Spatial analysis can be used to determine the potential of component sustainable food farming in province based on data and supporting information. The purposes of this study are (1) To analyze the projection needs of wetland at the provincial and district levels, (2) To identify potential land for prime sustainable food farming land and reserve sustainable food farming land at the provincial and district levels, (3) To define potential locations for the proposed as the sustainable food farming region at the provincial and district levels. The results show that the availability of land is the main deciding factor, otherwise suitability of land has not influence in deciding of sustainable food farming area. At the provincial level, the result shows that more general planning area proposed, including assemblage of some small regions, and indication of prime and reserve land. The proposed planning at the provincial level is a reference in the preparation of the proposed planning district, with more a detail data for regions, prime and reserve land along with prediction size of area.

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.
