Abstract

The purpose of the PDTI program's community service activities is to achieve economic independence through the processing of OPEFB into geotextiles and creative industries. The implementation method uses training and assistance in processing OPEFB into fiber using fibrillation milling tools and arranging them into non-woven textile sheets to be applied in diversifying products with high economic value. Participants in PDTI activities are farmer groups from Wirajaya Village, Bogor Regency, which is <100 m from the IPB Dramaga. The evaluation instrument uses pretest and posttest on the quantitative value of knowledge, skills, and motivation in absorbing the technology provided through training. The results of the evaluation showed a significant improvement in people's knowledge, skills, and motivation. This program not only opens up new business opportunities but also contributes to environmental conservation through organic waste reduction and the promotion of a circular economy. In addition, this program has also increased to have a positive impact on the community in terms of knowledge, motivation, and skills. Meanwhile, the results of intensive training and assistance to the community are also able to convert waste into value-added products such as nonwoven geotextiles.

Abstract

Information on metal adaptation in plants is essential to understand the mechanism of heavy metal remediation, including lead (Pb), mediated by forest plants in contaminated land. This study aimed to identify the adaptation mechanism of jabon (Anthocephalus cadamba Roxb.) seedlings to excessive lead levels based on the tolerance index of growth performance and lead transport to plant tissue. The seedlings were exposed to lead Pb(NO₃)₂​ at concentrations of 0, 0.5, 1, 1.5, 5, and 10 mM in nutrient culture for 15 days. The results showed that the tolerance index (TI) of the seedlings significantly decreased with Pb exposure up to 1.5 mM, although the TI values remained above 75%. All seedlings died at Pb concentrations of 5 mM and above. Lead accumulated in all parts of the seedlings, with the highest concentration found in the leaves (735.9 ppm) under 0.5 mM Pb exposure. Pb was transported to the upper portion of the seedlings, as indicated by a transport factor (TF) greater than 1. The results suggest that jabon can tolerate excessive Pb exposure up to 1.5 mM and has potential as a phytoremediator plant.
