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: Penetapan Umur Simpan Telur Asin Rendah Kolesterol pada Penyimpanan Suhu Ruang
Abstrak: Pemanfaatan telur bebek sebagai bahan pangan salah satunya yaitu telur asin. Namun, muncul kesadaran masyarakat akan tingginya kandungan kolesterol pada telur asin sehingga dikembangkan inovasi telur asin rendah kolesterol. Produk telur asin di pasaran memiliki umur simpan pendek tetapi belum diidentifikasi parameter penentu kerusakan produk. Penelitian ini bertujuan untuk mengetahui perubahan mutu dan menetapkan umur simpan telur asin selama penyimpanan suhu ruang. Penelitian ini dilakukan dengan membuat telur asin kemudian dilakukan pengemasan vakum, lalu disimpan hingga terjadi kerusakan pada suhu ruang. Penentuan umur simpan dilakukan dengan metode extended storage studies berdasarkan parameter kadar air, pH, kadar kolesterol, kecerahan, organoleptik, serta uji total plate count. Hasil karakteristik penyimpanan hari ke-10 telur asin diperoleh nilai tingkat kecerahan putih telur sebesar 25,96, kecerahan kuning telur 25,98, pH 7,19, kadar air putih telur 84,64%, kadar air kuning telur 38,72%, dan total mikroba 4,1 × 105 cfu/mL. Kadar kolesterol sebesar 233,39 mg/100 g pada hari pertama dan mengalami penurunan menjadi 131,61 mg/100 g pada hari kesepuluh. Mutu telur asin mengalami perubahan yang mengarah pada kerusakan selama penyimpanan suhu ruang. Telur asin tanpa kemasan memiliki umur simpan hingga 9 hari dengan total mikroba sebesar 1,0 x 105 cfu/mL., The utilization of duck eggs as a food ingredient includes salted eggs. However, public awareness of the high cholesterol content in salted eggs has led to the development of low-cholesterol salted egg innovations. Salted egg products in the market have a short shelf life, but the determining parameters for product spoilage have not been identified. This research aims to understand the quality changes and establish the shelf life of salted eggs during room temperature storage. The study involves producing salted eggs, vacuum packaging them, and then storing them at room temperature until spoilage occurs. The determination of the shelf life is based on extended storage studies, considering parameters such as moisture content, pH, cholesterol content, brightness, organoleptic, as well as a total plate count test. The characteristic results after 10 days of storage show that the brightness of the egg whites is 25.96, the brightness of the egg yolks is 25.98, pH is 7.19, the moisture content of egg whites is 84.64%, the moisture content of egg yolks is 38.72%, and the total microbial count is 4.1 × 105 cfu/mL. The cholesterol content decreases from 233.39 mg/100 g on the first day to 131.61 mg/100 g on the tenth day. The quality of salted eggs undergoes changes that lead to spoilage during room temperature storage. Unpackaged salted eggs have a shelf life of up to 9 days with a total microbial count of 1.0 x 105 cfu/mL.
