Kinetics Of Silica Precipitation In Geothermal Brine With Seeds Addition: Minimizing Silica Scaling In A Cold Re‑injection System
SETIAWAN, Felix Arie; RAHAYUNINGSIH, Edia; PETRUS, Himawan Tri Bayu Murti; NURPRATAMA, Muhammad Istiawan; PERDANA, Indra (Geotherm Energy, 2019-12-01)The utilization of geothermal energy remains underdeveloped, mainly due to the technical problem of silica scaling. The scaling can eventually disrupt the electricity production process due to frequent pipe maintenance. ... -

Microencapsulation of betacyanin from red dragon fruit (Hylocereus polyrhizus) peels using pectin by simple coacervation to enhance stability
RAHAYUNINGSIH, Edia; SETIAWAN, Felix Arie; RAHMAN, Ahmad Badawi Kasyfur; SIAHAAN, Tomimoto; PETRUS, Himawan Tri Bayu Murti (J Food Sci Technol, 2020-11-01)Betacyanin is a red natural dye pigment widely used in food products. However, the pigment is also unstable and easily degraded by temperature during storage and food processing. This research aims to increase the stability ... -
Optimization Model on the Effect of Clove Oil, Formaldehyde, and Chitosan Added to Batik Fabric Colored with Gambier (Uncaria gambir Roxb): Antifungal Properties and Stability
RAHAYUNINGSIH, Edia; SETIAWAN, Felix Arie; AYANIE, Conny Julanda; ANTOKO, Ambrosius Aditya; AYUNINGTYAS, Yosephine Intan; PETRUS, Himawan Bayu (Indonesian Journal Of Chemistry, 2019-06-02)Triggered by the concept of sustainability, the use of natural dyes in batik fabric processing has increased recently. To inhibit fungus growth on batik fabric colored with natural dyes, either clove oil or formaldehyde ... -
A Study On The Effectiveness Of Antifungal Agents On Cotton Fabrics Colored By Gambir Natural Dyes (Uncaria Gambir)
RAHAYUNINGSIH, Edia; SETIAWAN, Felix Arie; AYANIE, Conny Julanda; ADITYA, Ambrosius; AYUNINGTYAS, Yosephine Intan (KONVERSI, 2019-04-01)The increasing interest in the use of natural dyes is not accompanied by sufficient information and method for the application due to broad natural dyes resources existence. Gambir (Uncaria gambir), one of promising ...
