Judul: Analisis Dan Desain Sistem Informasi Bisnis  Pada Koperasi Susu Menggunakan Uml  (Unified Modelling Language)
Abstrak: This work proposes an application for business information system in a cooperation of diary enterprise. UML (Unified Modelling Language) diagrams were deployed to analyze and design all requirements in the development by using a CASE (Computer-Aided Software Engineering) tool called Sybase Power Designer 15.3. The object oriented analysis was conducted by creating use case diagram, activity diagram, and sequence diagram. The designing process was conducted by creating a class diagram from the diagrams which are already created in the analysis. The main diagram in this research was the class diagram from which the PDM (Physical Data Model) would be generated. From this PDM, a database was generated as the inputs to this application. This system was developed by using NetBeans with MVC method, which separates the system into three components, which are the model, the view, and the controller. This system could produce reports which were generated by plug-in iReport 4.0.1. These reports are sales report, farmers report, customers report, loans report, purchasing report, remuneration report, and products report. System testing was conducted by black-box method by inputting some samples of data to the system by the user. This system should be able to manage sales data, loans data, products data, farmers data, and other transactions data

Judul: Sistem informasi bisnis berbasis UML(Unified Modeling Language) untuk agroindustri biopelet limbah pelepah sawit
Abstrak: Development of palm oil midrib biopellet business needed complete, integrated and up to date information. The objectives of this work is to identify critical factors in biopellet midrib palm oil business, to design an UML-based business information systems for biopellet agro-industry, and to evaluate the results of business information systems. The modeling is based on the object-oriented system development using UML (Unified Modeling Language) which consisted of use case diagrams, activity diagrams, collaboration diagrams, sequence diagrams, class diagrams, and physical data model. Critical factors in biopellet midrib palm oil business were the availability of raw materials or oil palm plantations, the balance of energy produced versus the energy required, the determination of industrial location, and scheduling the location of raw materials and investment feasibility. The developed business information system, more efficient in program code usage and easy to develop. Keyword: UML, biopellet, business information system, object oriented system, petiole, midrib palm oil.

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.
