Abstract

Patchouli plant is one of main agricultural commodities in Indonesia with an area of 64.67 ha. The solid waste produced from the distillation industry is around 98% of total feedstock. The aim of this research is to disclose the characteristics of solid waste biomass from patchouli essential oil industry harvested from Lhokseumawe, Indonesia. The properties of patchouli biomass before and after distillation was analyzed by using a number of techniques including proximate, bomb calorimeter, TGA-DTG, DSC and lignocellulosic analyses. Five kilograms of biomass was collected after patchouli harvesting then sorted into four categories i.e. leaves, branches and trunk. and mixture of all. Another set of biomass residue was collected after distillation process and grouped similar to those collected before distillation. All samples were then dried, ground and sieved to 50 mesh size. The analysis results showed that the highest heating value was observed from the sample of patchouli leaves collected before distillation process with a value of 15.65 MJ/kg where its volatile matter content was 81.26%. Compositional analysis of lignocellulosic suggested that 27% in pre-distilled branches. Mixture of all parts was found to contain 35% cellulose that was the highest. Lignin content with 42% value was found in after distilled trunk.

Abstract

Because free fatty acid content impacts crude palm oil's physical and chemical characteristics, it is a good indicator of the oil's quality. Investigated effective operating parameters include contact time on adsorption and initial free fatty acid concentration. This system was studied using Langmuir and Freundlich isotherms, and the kinetic data was examined using pseudo-first-order and pseudo-second-order models. The findings indicated that increasing FFA concentrations increased the adsorption capacity of free fatty acids using Ujong Pacu bentonite, and it was discovered that CPO weighing 30 g was the ideal weight for FFA adsorption capacity. At equilibrium, the ideal value of adsorption capacity is 502.17 mg/g. While the pseudo-second order model is the model that best describes the adsorption kinetics of the free fatty acid content in Crude, the Freundlich isotherm model best describes the equilibrium data, which indicates the heterogeneous surface of the adsorbent pores and shows that the adsorbate layer formed on the surface of the adsorbent is multilayer. Correlation coefficient (R2) for palm oil (CPO) in the range of 0.946 to 0.9975.
