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

The development of a portable ladder for pepper harvesting in Sanatap Village, Sajingan Besar Sub-district aims to improve farmers' ergonomics, safety, and productivity. Using the Quality Function Rapid Entire Body Assessment (REBA) dan Deployment (QFD) methods, this study identified farmers' key needs such as ease of operation, lightweight materials, and ease of storage. The designed ladder is foldable, has wheels, and is made of strong yet lightweight galvanised iron, and has additional safety features. The results of the analysis showed a significant improvement in the farmers' working posture and a reduction in the risk of injury, from moderate risk (REBA score 4-7) to low risk (REBA score 2-3). This shows that the ladder can reduce the risk of injury to pepper farmers. In addition, this portable ladder is expected to not only improve the efficiency and safety of pepper farmers, but also open new business opportunities that contribute positively to the local economy. The implementation of this tool is expected to improve the welfare of farmers in Sajingan Besar Sub-district and provide practical solutions that are profitable and sustainable.
