Judul: Studi Literatur: Pengaruh Laktoferin Susu Sapi terhadap Sistem Imun Pengidap COVID-19
Abstrak: Infeksi virus SARS-CoV-2 (Severe acute respiratory syndrome Corona Virus 2) menyebabkan masalah kesehatan serius di seluruh dunia. Virus tersebut telah menginfeksi jutaan orang melalui beberapa jalur umum, termasuk transmisi langsung, yang menyebabkan penyakit COVID-19 (Coronavirus Disease 2019) serta memicu terjadinya imunopatologi. Vaksin yang efektif dan bahan antiviral dibutuhkan untuk mencegah mortalitas. Salah satu bahan antiviral yang potensial melawan virus tersebut adalah laktoferin susu sapi (bLf). Penelitian ini bertujuan mengkaji potensi bLf terhadap sistem imun pengidap COVID-19. Data yang digunakan pada penelitian ini merupakan data sekunder yang berasal dari berbagai literatur atau sumber yang valid dan diterbitkan pada kurun waktu 10 tahun terakhir (2013-2023). Data tersebut dianalisis menggunakan metode tinjauan pustaka. Hasil penelitian ini menunjukkan adanya pengaruh laktoferin susu sapi pada pengidap COVID-19, terutama pada pengidap yang memasuki fase awal infeksi. Pemberian laktoferin susu sapi terhadap pengidap COVID-19 pada fase menengah hingga akhir infeksi tidak berpengaruh terhadap percepatan kesembuhan pengidap.

Judul: Literature Review: The Effect of Lactoferrin Fortified Formula Supplementation on Infants Under Twelve Months
Abstrak: Salah satu komponen fungsional dalam susu adalah laktoferin yang merupakan protein pengikat besi multifungsi yang memainkan peranan penting dalam regulasi imun. Studi ini bertujuan membahas pengaruh suplementasi susu formula yang difortifikasi laktoferin pada bayi di bawah dua belas bulan. Studi dilakukan menggunakan metode studi literatur berdasarkan artikel ilmiah menurut kata kunci (Lactoferrin, infant, infant formula, dan bovine lactoferrin). Data kemudian dianalisis menggunakan analisis deskriptif. Berdasarkan hasil studi pustaka, dapat disimpulkan bahwa bLf aman dan mampu mengatasi beberapa penyakit baik melalui pemberian oral maupun fortifikasi makanan serta terkait dengan pertumbuhan bayi normal di bawah usia dua belas bulan. Konsumsi susu formula yang difortifikasi laktoferin sapi memberikan efek yang signifikan pada total kandungan zat besi tubuh dan perbaikan jumlah hemoglobin bayi. Fortifikasi bLf ke dalam susu formula meningkatkan nilai fungsional susu formula, namun tidak signifikan menurunkan angka mortalitas bayi., One of the functional components in milk is lactoferrin which is a multifunctional iron-binding protein that plays an important role in immune regulation. This study was aimed to examine the effect of lactoferrin-fortified formula supplementation on infants under twelve months of age. The study was conducted by using a literature study method based on scientific articles according to keywords (Lactoferrin, infant, infant formula, and bovine lactoferrin). The data were analyzed using descriptive analysis. Based on the results of the literature study, it can be concluded that bLf is safe and able to overcome several diseases either through oral or food fortification, and is associated with normal growth of infants under the age of twelve months. Consumption of formula milk fortified with bovine lactoferrin has a significant effect on the total body iron content and improvement in the hemoglobin count of infants. Fortification of bLf into infant formula increased the functional value of formula milk, but did not significantly reduce infant mortality.

Judul: Separation of Neodymium from U3Si2/Al Fuel Plate for Burn-Up Determination
Abstrak: Neodymium is a common fission product produced in nuclear fission reactions. Neodymium in this study was chosen as a burn-up indicator for U3Si2/Al fuel element plates because the neodymium isotope is a stable fission product with a fairly high yield. Some procedures were carried out to separate neodymium, starting with the separation of cesium isotopes (137Cs, 134Cs) through the precipitation method, then separation of uranium isotopes (235U, 238U) and plutonium isotopes (239Pu, 238Pu) with Dowex 1x8 ion exchange resin, and separation of neodymium (Nd), samarium (Sm), as well as cerium (Ce) with Dowex 1x4 ion exchange resin. The Cs recovery reached 99.95%. The U and Pu isotopes resulting from the separation are subjected to an electrodeposition process and the weight of each isotope can be measured with an alpha spectrometer. The separation results of Nd from Sm and Ce have been proven using an XRF spectrometer. The neodymium isotopes separation was corrected using the standard addition method, and an average total Nd content of 2.4 ppm was obtained in the PEB U3Si2/Al bottom solution. It is hoped that this separation method can be applied in determining burn-up of nuclear fuel.
