This research aims to study the first-order kinetics of biodiesel production from used frying oil (UFO) through transesterification with methanol. Used frying oil was collected from fried peddlers around the campus of the University of Lampung. Technical ... 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

In this study, dragon fruit was dried by a microwave-assisted foam drying method and the effect of different microwave powers (350, 460 and 700W) on the drying kinetics and powder product properties were investigated. The properties (foam stability, expan... 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

In this paper, the modelling, numerical lumping and simulation of the dynamics of one-dimensional, isothermal axial dispersion tubular reactors for single, irreversible reactions with Power Law (PL) and Langmuir-Hinshelwood-Hougen-Watson (LHHW)-type kinet... see more

The main bottleneck in fermentation technology is scaling up procedure of industrial enzymes according to the biological characteristics of the organism. The current study describes the production kinetics of cellulases in stirred tank reactor by using mu... see more

In the work, the kinetics of the release of vitamin E and polyphyte oil from capsules was studied using synthetic and natural systems. The release of active ingredients was monitored on a Cary 50 Cons UV spectrophotometer equipped with CaryWinUV software.... see more

The curing kinetics of the epoxy resin crosslinked by an anhydride hardener with and without plant fibers was investigated. The epoxy composites containing modified pineapple leaf fiber (EASF), banana fiber (EBSF), and bamboo chopsticks fibers (ECSF) were... 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
