The object of research is the process of oxide reduction in a reaction system of mass m due to the reaction on a contact surface with an area of S.An adaptive technology is proposed that allows one to construct the kinetic equation of the process in which... see more

Pyrolysis at the temperature range of 170 °C-237 °C against polystyrene (Styrofoam) type plastic waste is carried out without a catalyst and added a catalyst. The purpose of this research was to study the reaction kinetics of Styrofoam pyrolysis to liquid... see more

The effect of varying Ag+ ion concentration on the green chemical reaction with a fixed tea aliquot concentration has been studied in detail with the help of UV-visible absorption spectra. With increase in the concentration of Ag+ solution the position of... see more

X-ray diffraction (XRD) is a powerful technique for the study of polymorphism and polymorphic phase transformations. Monitoring of phase transformation directly has been very limited to-date. The XRD system used in this study was used to determine the rat... see more

Furfural adalah salah satu bahan kimia penting yang dapat diubah menjadi berbagai bahan kimia seperti furfuryl alkohol dan asam levulinat. Furfural dapat diproduksi dari biomassa lignoselulosa dalam kondisi asam dengan mengkonversikan fraksi hemiselulosa ... see more

In the present study, a kinetic model of nitration between glycerol and nitric acid was developed. The presented model describes three controlling reactions model used elementary reactions consisting of three reversible reactions. The model utilizes first... see more

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

In the ozonation process, the phenol degradation in wastewater undergoes a low mass transfer mechanism. In this study, ozonized packed bubble column reactor was designed and constructed to remove phenol. The reactor’s inner diameter and height were 150 an... see more

The color of food is an important attribute for consumer choice. Browning is desirable in some foods due to the color and flavor it produces (such as in bread and roasted meat), but is undesirable for others (such as heat-treated milk). The Maillard react... see more
