Speed and simplicity in the process of finding documents and information have become a necessity in the campus library. The speed in finding a skripsi document that is currently still very long to find the data and more simple in displaying what you are looking for then we aim to search and find skripsi documents in a digital library at a private university in Jakarta more quickly and display what which is searched precisely. An approach is needed using the VSM method that encourages without complete keywords, and to see the effectiveness of research searches. The results of the VSM method can be applied for the development of prototype applications. The prototype used to facilitate the process of searching or finding the documents and information needed is fast and simple.

<p><strong>Objective</strong>. The longevity of vaccine effectiveness and antibody titer after the Moderna mRNA COVID-19 vaccination booster in healthcare workers in Indonesia is not known.</p><p><strong>Materials and Methods</strong>. We performed a prospective observational study of healthcare workers at the Universitas Indonesia Hospital after Moderna mRNA COVID-19 booster vaccination. An Immunology Analyzer with Chemiluminescence Immunoassay (CLIA) test was used to examine Anti SARS-CoV-2 S-RBD levels. Antibody levels were classified into two systems (3 categories, and 2 categories).</p><p><strong>Results</strong>. There were 31 male subjects (75.6%), 33 subjects (80.5%) aged 25-39 years, 17 subjects (41.5%) with overweight BMI, 35 subjects (85.4%) without comorbidities, and 29 subjects without previous history of COVID-19 infection (70.7%) who had antibody titer &gt;1000 AU/ml. There were 27 subjects (65.9%) who had a booster shot ≥6 months after the second vaccination with antibody titer &gt;1000 AU/ml. In this study, there was no significant correlation between antibody titer with factors such as gender, age, BMI, comorbidities, history of COVID-19 infection and time between the 2nd vaccination and booster vaccination.</p><p><strong>Conclusion</strong>. There is no significant correlation between antibody titer with factors such as gender, age, BMI, comorbidities, history of COVID-19 infection and time between the 2nd vaccination and booster vaccination</p>

Penggunaan jaringan internet dan telepon yang telah menyebar ke daerah terpencil membuat masyarakat menjadi lebih konsumtif dalam melakukan pembelian pulsa mereka sendiri. Dengan meningkatnya frekuensi penggunaan komunikasi dan data internet, Indonesia menjadi negara yang menguntungkan bagi operator seluler. Pada pertengahan 2015, Indosat memiliki 68,5 juta pelanggan, naik 24,7% dibanding periode yang sama tahun lalu 54,9 juta pengguna. Tujuan dari penelitian ini adalah untuk mengetahui faktor-faktor penentu loyalitas pelanggan khususnya kualitas dan harga produk. Metode penelitian yang digunakan adalah deskriptif kuantitatif, dengan menggunakan sampel 100 mahasiswa pengguna IM3 Ooredoo dari tiga perguruan tinggi di Jabodetabek. Hasil peneltian menunjukkan nilai R square sebesar 62,9% , yang mengindikasikan loyalitas pelanggan ditentuka oleh kualitas produk dan harga secara posistif dan signifikan dengan persamaan regresi Y = 2, 942 + 0, 683 X1 +0, 346 X2. Terjadi hubungan atau pengaruh dalam menciptakan loyalitas pelanggan baik secara simultan atau parsial.
