| dc.description.abstract | Polybags are a seed planting medium that is generally made of plastic. The use of
plastic-based polybags is considered less environmentally friendly because of the
presence of plastic packaging, which will be thrown away when the seeds are
transferred from the polybag to the ground. Therefore, it is necessary to look for
alternative plastics in the form of organic materials that are more
environmentally friendly when making polybags. This research aims to produce
polybag based on a mixture of empty fruit bunch compost (EFBC) and wet
decanter solid (WDS) with chitosan adhesive, as well as analyzing the properties
of the resulting polybags including density, moisture content, water absorption
capacity, pH, biodegradation, and rate growth. The production of media tanams
wass carried out with EFBC:WDS ratio of 90:10, 80:20, 70:30, 60:40, and 50:50.
The results showed that increasing the amount of EFBC will increase the density,
moisture content, and pH of polybag, but reduced the absorption capacity and
biodegradation of polybag. The best polybag composition was obtained with an
EFBC:WDS ratio of 70:30, with a density of 0.70 g/cm3, moisture content of
10.62%, absorption capacity of 8.30%, pH of 6.6, and biodegradation of 43.41%.
The use of polybag resulted in wheatgrass growth of up to 11.4 cm on the 14th
day. The success of this research can make polybag an alternative to ordinary
polybags because they can practically be planted directly into the ground without
having to open the container. Apart from that, it is hoped that polybag can
decompose quickly and not cause environmental. | en_US |
