4 Main Objectives Planning and establish solutions of community based on natural resources management for
reduction of environmental and resources deterioration
5 Focal Points All activities will be conducted at the laboratories and at sites that focus on three areas of rural,
urban and industry (figure 1): Some main achieved activities:
▪ Interview and survey have been done (rural
area, industrial area, and forests of mangrove
and melaleuca).
▪ Experiments on lab. scale and field study have
been conducted and data is continuously
collected.
▪ First data collection and analysis have been
carried out and some manuscripts have been
submitted.
▪ Some more data collection and related data
analysis are expected to collect for further
manuscripts writing.
▪ Some activities have been delayed by Covid-19
during March to June, especially the
conference participatory

Some main results have been recorded as follow:
To use water lecture
(Pistia stratiotes) for
removing nutrients (N-
NH 4 , + N-NO 3 ) - in
wastewater after biogas
digester, it is important to
know what levels of
nitrate, ammonium that
water lecture can tolerant.
It was found that after 3
days water lecture was
abnormal as [N-NH 4 ] >
