In order to manufacture a workpiece fulfilling specified requirements with the lowest possible weight, it is crucial to be able to work with a variety of materials and to combine them accordingly.
The production of profiles based on hybrid materials demonstrates such an approach.
Therefore, the material flow plays an important role.

INTRODUCTION Activated charcoal is a fine black odourless and tasteless powder made from wood or other materials such as palm shell, coconut shell, etc.
MATERIALS AND METHODS Paraquat was purchased from local company which was the standard for testing agricultural chemical residues.
The palm shell particles were soaked with 5% acid solution to loosen the fiber and other trace materials.
Treatment of the raw material of adsorbent loosen the fiber and other trace materials, therefore it reduces interference during the carbonization process.

The contamination hazard from ambient air mainly appears in the human health, agriculture, forestry and materials.
Based on the relations between concentration and sources and the loss calculation for pollution hazards, a model for regional atmospheric environmental capacity can be established with largest allowed emission(least abatement cost) and least loss by contamination (herewith only concerning the losses to human health, agriculture and forestry by the air pollution without the loss to materials).

In this research, the development of three (3) low-cost adsorbent materials from abundant waste rice husk was achieved via thermal treatment.
Consequently, there has been a growing interest in developing and implementing various potential adsorbents for the removal of phenol from water, and researchers are always in a hunt for developing more suitable, efficient, cheap and easily accessible types of adsorbents, particularly from the waste materials.
Material and Methods Development and characterization of Adsorbents.
The raw material, rice husk (RH), was obtained from a nearby rice mill.

Analysis research was done by observing trends in journals, authors, and keywords.
Materials and Method The literature review is one of the most important elements in research to map and review relevant literature and identify research gaps that will help strengthen further research that researchers can carry out.
Several articles published in the same journal, namely the Journal of Automation in Construction Automation in Construction, contained 3 articles, in the IEEE Transactions on Biomedical Engineering, there were 3 articles and 2 articles in the Journal of Mechanics in Medicine and Biology.
Fig. 3 presents the articles in journals published from 2012 to 2022.
The creation of high-frequency keywords enables academics to identify the main developments in cognitive science.
