Judul: Analisis Kebutuhan Sistem Pemrosesan Transaksi Pengajaran Taman Kanak-kanak Menggunakan Zachman Framework
Abstrak: Early childhood is the most important phase in human life because all aspects of human life grow so fast. Therefore, providing good quality education for childhood has to be the main focus. The core competence of kindergarten teacher is pedagogic. It is related to teacher’s ability to design learning activities and to evaluate student learning outcomes. The existence of computer application can help teacher while making lesson plan, recording student progress in the class, and reporting student final result. Zachman Framework becomes a tool that can used to analyze the requirement of Transaction Processing System for Kindergarten Teaching. This research uses three of six perspectives in Zachman Framework to collect requirements. Each perspective is depicted by several artifacts. The Executive Perspective is identified by 18 entities, vision and mission of the kindergarten, address of kindergarten, 6 important timing and 13 main process. The Bussines Owner Perspective is defined by 6 entities at ERD, activity diagram, master schedule, 5 goals, and organizational chart. The Architect Perspective is represented by 22 entities at ERD, 7 processes using activity diagram, state diagram, and 25 data integrity constraints. This requirement analysis document is useful as a blueprint for the next stage of development

Judul: Analisis Kebutuhan Sistem Informasi Manajemen Produksi CV. NIK’S PROMINDO SEMESTA Menggunakan Framework Zachman
Abstrak: Production is changing input to output through a few of particular process. The cultivated input, resulted output, and also process of production are needed factors for production information system. CV.NIK’S PROMINDO SEMESTA (NPS) is the one of organization which needs the information system to manage its business process. However, the lack of understanding, regarding the information system can obstruct the activities of the company especially in making decisions to increase the quality of the product and the business performance. Production information system is expected to help reduce that problems. In order to develop the production information system, the requirement analysis of the system requires the necessity of the company. Zachman framework provides a framework to develop the formal and structured system architecture. Through the method adopted by Sousa and Pereira, each description of business object relationships can produce consistent analytical results. The flexibility of defining Zachman may facilitate analysts to describe the needs of the organization on the development of management information systems production. The result of this research includes the system architecture such as: the requirement diagrams and naration that will be used by developers to develop the system according to the requirements.

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.
