Pemanfaatan Ekstrak Daun Jambu Biji (Psidium juajava) sebagai Inhibitor Korosi Pada Baja
Authors: Prameswari Apriska , Dahlan Dahyunir 
Published: March 2022

Penelitian ini membahas tentang sintesis lapisan antikorosi menggunakan ekstrak daun jambu biji (Psidium guajava) Â sebagai inhibitor korosi pada baja. PelapisanÂ dilakukan dengan metode elektrodeposisi yang bertujuan untuk mendapatkan lapisan tipis untuk melindungi permukaan baja. Pembuatan lapisan diawali dengan mencampurkan CuSO4Â 1 M, asam borat (H3BO3) 0,24 M, dan aquades yang kemudian diaduk dan ditambahkan inhibitor ekstrak daun jambu biji dengan variasi konsentrasi 0%, 0,1%, 0,2%, 0,3%, 0,4%, 0,5%, 3%, 5%, 7%, dan 9% volume inhibitor. Media korosif dibuat dengan melarutkan 3,65 g HCl ke dalam 100 mL aquades dan perlakuan korosif diberikan selama 10 jam pada suhu ruang. Pengukuran laju korosi baja dilakukan menggunakan metode weight lossÂ yang juga akan menghasilkan nilai efisiensi inhibisi baja. Nilai laju korosi dan efisiensi inhibisi paling optimal adalah pada konsentrasi 5% yaitu sebesar 0,00085 g/cm2.jam, dan efisiensi inhibisinya sebesar 74,6269%. Konsentrasi yang semakin meningkat akan menghasilkan laju korosi yang semakin kecil jika konsentrasi inhibitor yang diberikan tepat. Pelapisan dengan metode elektrodeposisi menghasilkan permukaan baja yang tebal, halus dan terlapisi dengan baik.

Published: March 2022

Проблема качества дорожных битумов в России была и остается актуальной. Решение данной проблемы видится в применении качественных адгезионных добавок. Применение импортных присадок к битумам существенно повышает их качество, но в то же время весьма существенная разница в ценах по сравнению с аналогами российских производителей. Однако, если анализировать по качеству дорожных покрытий и долговечности, то использование адгезионных добавок зарубежных производителей может быть выгоднее применительно к битумам, планируемых получать из нефтей месторождений Чеченской республики.
The problem of the quality of road bitumen in Russia has been and remains relevant. The solution to this problem is seen in the application of highquality adhesive additives. The use of imported additives to bitumen signifi cantly improves their quality, but at the same time, a very signifi cant difference in prices compared to analogues of Russian manufacturers. However, if we analyze the quality of pavements and durability, then the use of adhesive additives from foreign manufacturers may be more advantageous for bitumens that are planned to be obtained from the oil fi elds of the Chechen Republic.

Authors: Prakash Gnana 
Published: March 2022

In the current study, ketoprofen emulgels were prepared using Sodium CMC, Sodium alginate and Hibiscus as gelling agents in order to overcome gastric side effects and to achieve pharmacological response. Pre formulation parameters were performed to know the compatibility of pure drug ketoprofen with polymers CMC, Na alginate, hibiscus prior to the preparation of Emulgel. It indicates that no change was observed in the peak values of the drug in the physical mixture thus providing that both the drug and polymer were said to be compatible with each other. Emulgel of ketoprofen 2.5% w/w was prepared in 3 steps i.e., Preparation of gel, emulsion phases separately and incorporate both phases in homogenizer for a period of 45 min and stabilized it for 2 hrs. The prepared emulgels were evaluated for physical characteristics, drug content, pH, spreadability and in-vitro permeation studies. The physical appearance of all the formulations was creamy white, consistent, homogenous and stable. The pH of the prepared emulgels was found well within the range of 6-7. Release rate kinetics of the drug was studied with in vitro drug permeation data for all the formulations F1 to F9 and results were stated the best fit model for selected formulation F6 were found to be Zero order model with non-fickian diffusion. The formulations were compared with the reference product. The in-vitro dissolution of F6 was nearest to the reference product F10 (f2 = 85.17).
