Based on Acceptable Daily Intake (ADI) on kalakai that grow on unburned peat soil and burned several times 81,76 µg/kg BB/hari dan 57,97 µg/kg BB/hari for Co and 112,56 µg/kg BB/hari dan 119,763 µg/kg BB/hari for Ni.

Communities play an important role in communal wastewater treatment plants (IPAL) because they are the users and owners of the wastewater sources that must be treated. This research aims to analyze the factors that influence Community Participation in the management of Communal Waste Water Treatment Plants (IPAL) in Kampar Regency. This research is quantitative with an analytical cross-sectional study design (Analytical Cross Sectional Study). The data in this research is primary data obtained by distributing questionnaires. The variables studied were the dependent variable (community participation in managing the Communal IPAL) and the independent variable (knowledge, education, economy and government support). The research results show that there is a significant relationship between economic knowledge (Pvalue 0.002) and government support (Pvalue 0.02) with community participation in the management of Communal IPAL in Kampar Regency. and there is no relationship between education and community participation in the management of Communal IPAL in Kampar Regency (Pvalue 0.069). It is hoped that the community can actively participate in the operation and maintenance of the communal IPAL and that the government will always accompany the community using the communal IPAL in operational and maintenance activities.
