Abstrak: Pembangunan hutan kota harus memperhatikan beberapa hal demi tercapainya tujuan dan keberhasilan pembangunan hutan kota, salah satunya adalah pemilihan tanaman yang sesuai dengan kondisi ekologis lokasi pembangunan hutan kota. Karakter tumbuhan juga harus sesuai dengan tujuan pembangunan hutan kota tersebut. Penelitian ini bertujuan untuk membuat sistem informasi mengenai tumbuhan. Dengan adanya sistem informasi dalam bentuk digital ini, diharapkan dapat memberikan kemudahan bagi siapa saja yang membutuhkan informasi untuk mengakses dan mencari informasi mengenai tumbuhan, terutama untuk pembangunan hutan kota.

Judul: Piranti lunak Sistem Informasi Hutan Kota Plant And Tree Information System (PLATIS).
Abstrak: The development of urban forest must consider the purpose for the successful development of urban forestry, one of which is those plant selected suitable with the ecological conditions where the urban forest will be estabilished. The characters of the plants that will be planted must also suit the purpose of the development of urban forest. The objective of this study was to create an information system of plants. Such information system will be developed in digital form, and would provide ease of access of the information on the selected plants. Information of plants that were be collected include scientific name, local name, rainfall, light inensity, altitude, soil type, soil texture, sollup, pH, Transpiration, CO2 absorption, salt endurance, pool endurance, canopy shape, canopy class, and the picture of plant. This study produce a system information software that named PLATIS (Plant and Tree Information System). PLATIS consist of three form, plant form, family form, and tutorial form. This software made using MS Visual Studios 2005 with database that made using MS Access XP, and using >NetFx (dotNetFramework) as a component to run this software.

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.
