| Summary: | Coal mining causes damage to the environment, especially the degradation of soil
quality, resulting in the lack of nutrients and organic matter in the soil. Reclamation
of disturbed land due to mining activities must be carried out and the selection of
commodities must be appropriate given the non-ideal conditions of the planting
area. Citronella (Cymbopogon nardus) is an adaptive plant in the post-mining
environment and can be utilized as a commodity that not only helps reclamation
activities but can be utilized as an economic product. The oil palm plantation
industry (Elaeis guineensis Jacq.) produces two types of waste that can be used as
organic fertilizer, namely waste of Empty Palm Oil Bunches commonly called
tangkos/jangkos and Wet Decanter Solid (WDS) waste commonly called solid.
Tangkos fertilizer, solid fertilizer and manure can be used to meet the nutritional
needs of citronella grass plants in order to produce optimal production. This study
aims to analyze the effect of a combination of manure, jangkos, and solid organic
fertilizers on the growth and biomass yield of citronella grass. The growth of
citronella grass was measured by variables of plant height, leaf length, number of
tillers, and canopy widht while biomass yield was measured by variables of leaf
fresh weight, shoot-root ratio, leaf moisture content, and citronella oil yield. This
study used manure derived from cow manure waste as well as jangkos fertilizer and
decomposed solid obtained from oil palm plantation areas. Based on the
quantification results of citronella (Cymbopogon nardus) Sitrona 2 Agribun plants,
it was found that the treatment of the composition of manure, jangkos, and solid
had no effect on plant growth variables such as leaf length, number of tillers, and
canopy width as well as on plant biomass results in the form of leaf wet weight,
shoot-root ratio, and leaf moisture content. The P1 treatment is the best treatment
on plant height variables. In the oil yield variable, the three treatments produced
different yield values, namely P2 (1.7%), P3 (1.42%), and P1 (1.08%). |
