Blue methylene is a cationic dye. It is usually as in various industries. The waste of blue methylene can reduce the environmental balance, especially for aquatic biota, by inhibiting the penetration of sunlight into the water. The experiment used the mos... see more

In the article “Kinetic Study & Statistical Modelling of Sarawak Peat Water Electrocoagulation System using Copper and Aluminium Electrodes” by Nazeri Abdul Rahman, Nurhidayah Kumar Muhammad Firdaus Kumar, Umang Jata Gilan, Elisa Elizebeth Jihed, Adar... see more

The kinetics study of NCA leaching in the HCl system was proposed. Various kinetic models such as shrinking core, logarithmic rate law, and Avrami equation were used to find out the most appropriate kinetic models for this process. The effect of HCl conce... see more

Amine-Modified Silica (AMS) and Quaternary Amine-Modified Silica (QAMS) has been synthesized through the sol-gel process for adsorption Au(III) in aqueous solution. The aim of this work was to compare the effect of addition three methyl group of AMS to fo... see more

From the analysis of zircon tailings using X-Ray Fluorescence (XRF), Yttrium is a rare earth element (REE) with the highest concentration compared to other REEs. The purpose of this study is to determine the best kinetic model for describing how sulfuric ... see more

The clay used taken from Lontor Village, Central Maluku Regency, Banda Besar Island. The clay was activated at 350 °C for 3 hours using a furnace. This study aims to determine the effectiveness of physically activated Lontor natural clay in reducing level... see more

Leaching of nickel laterite ore at atmospheric pressure is a leaching method that can be operated at >100°C temperatures in an atmospheric pressure, which is applicable to a low-grade laterite ore. This research aimed to study the effect... see more

The liquid extract of antihypertensive herbs could reduce blood pressure equivalent to Hydrochlorothiazide 25 mg based on research conducted in “Hortus Medicus” clinic, Tawangmangu, Central Java, but parameters of herbal medicine taste, design, and packag... see more

Quantitative analysis of bioactive peptide mostly conducted by measuring the activity. While the determination of peptide content in natural sources has been conducted using various instruments, vibrational spectroscopy remains underutilized. Here, we att... see more
