Judul: Object relational mapping pada pengembangan enterprise resource planning
Abstrak: Enterprise Resource Planning (ERP) merupakan suatu aplikasi terintegrasi yang difokuskan untuk mengotomasi seluruh aktivitas infrastruktur pada suatu perusahaan. Sistem ERP menggabungkan proses bisnis antara perusahaan dan pelanggan, perusahaan dengan supplier, dan proses perhitungan keuangan perusahaan. Semua proses bisnis yang tergabung mengakses pada sebuah basis data yang terpusat. Sistem manajemen basis data yang banyak digunakan pada aplikasi ERP adalah basis data relasional, sedangkan pengembangan aplikasi skala enterprise sebagian besar menerapkan konsep berorientasi objek. Dengan demikian terdapat ketidaksesuaian antara basisdata relasional yang digunakan dengan aplikasi yang dikembangkan dan pendekatan berorientasi objek. Ketidaksesuaian tersebut antara lain terkait dengan aspek granularity, subtypes, identitas, asosiasi, dan navigasi data.

Judul: Penerapan Object Relational Mapping pada Studi Kasus E-commerce
Abstrak: Application development with object-oriented approach has many advantages, such as: easy to maintain, scalable, and flexible. Those advantages will become irrelevant if the developed application needs relational database and is not handled well. Application development with an object-oriented and relational database approach potentially create problems, therefore a technique to link both concepts is needed. one of the popular techniques to overcome existing problems between the object-oriented and relational database approach is Object Relational Mapping (ORM). In this research, an object-oriented e-commerce application and relational database approach was developed. To solve a concept difference between object-oriented and database approach, a Hibernate framework is used. Hibernate is one of the tools that utilize ORM's ability to link those two different concepts. Research shows that an e-commerce application development by using ORM technique can make a database organizing process easier so that the applications that are being developed can be managed better.

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.
