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: Land Use Planning for Paddy Field Development in Pandeglang Regency
Abstrak: Food security is a big issue in Indonesia due to the availability of agricultural land caused by land conversion, especially in Java Island, is continually decreasing. Food security is the condition to meet food demand for the state to individuals, as reflected in the availability of sufficient food, both in quantity and quality, safe, diverse, nutritious, equitable, and affordable, and does not conflict with religion, belief, and culture of the community, to live a healthy life, active life, and productive in a sustainable manner. Therefore, the availability of agricultural land is one of the things that should be considered to ensure future food security, since agricultural land has a comprehensive function covering economic, social, and environmental aspects. However, the trend of agricultural land conversion in Java Island is very concerning. Several policies have been issued to tackle this problem, mainly LP2B (protected agricultural area) and the zoning regulation in spatial planning. However, further directives on these policies must also be formulated to give a further insight and some more comprehensive strategies on agricultural development. Pandeglang Regency is the largest rice production area in Banten Province, with the agricultural sector as the main economic activity in this region. Pandeglang Regency has potential in the agricultural sector, and agricultural land for food agricultural commodities, especially lowland rice, has the potential to be developed. Pandeglang Regency is also experiencing growth due to the enactment of Tanjung Lesung as a Special Economic Zone and various infrastructure development. However, the allocation and strategy for the agricultural area, especially rice/paddy fields, are still lacking and not detailed enough. Therefore, the analysis of the availability and needs of food land can be used to determine the minimum need for food land in Pandeglang Regency. This research aims to give directives on planning and development for the paddy field in Pandeglang Regency by giving an insight on its characteristics, availability, suitability, and potential in each region to be developed based on the spatial analysis result. The dynamics of land use change over the last 13 years in Pandeglang Regency are dominated by the increase of settlement areas, and the decrease of paddy field in contrast. The tradeoff between settlement and paddy field appears to be disproportional, where the rate of increase in settlement area is significantly bigger than the decrease of paddy field, meaning that the settlement area also converts other land uses as well. The other land uses experienced fluctuating change, such as plantation, shrubs, mix garden and bare land. Then this landuse trend are followed with CA-Markov prediction with business as usual (BAU) scenario. The prediction reached a good level of accuracy with kappa index of 0.89, with the end-year for land use prediction are set at 2031 following the year of spatial planning policy. Land use prediction using a CA-Markov method finds out that under BAU condition, settlement areas will continue to increase until the year 2031, with the rate of annual increase stays roughly the same. Meanwhile, the paddy field conversion in 2031 seems to have slowed down, following the 2012-2018 trend. It happened due to

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.
