Abstract

The COVID-19 pandemic encouraged efforts to find it’s prevention and treatment. The Indonesian state has a diversity of plants, many of which have anti-microbial effects. Singawalang plant (Petiveria aleaceae) has been used as an alternative treatment for tuberculosis, malaria, and other diseases in Indonesia and other countries. Active ingredients of this plant are flavonoids and several types of amino acids, which are contained in the leaves and roots. In addition to its use as a medicinal plant, Singawalang is also useful as an insecticide and akarisida for plant pests and ticks in livestock. The main problem of the sustainable use of natural / international scale medicinal plants is its raw material, while Singawalang has not been cultivated in Indonesia. The purpose of this study is to investigate the role of dolomite, zeolite, and NPK fertilizers in increasing nutrient absorption and growth Singawalang.in entisol soils. P. alleaceae were planted in polybags using entisol soils medium by Completely Random Design (CRD). Zeolite, Dolomite (2.5 tons / ha) and NPK Fertilizer 15:15:15 at a dose of (0; 1.5; 3; 4.5) g / plant were applied. The results showed that the amendment application had a significant effect on the number of leaves but it did not significantly affect other growth parameters and nutrient absorption of NPK. In general, Zeolites can increase growth and absorption of nutrients higher than Dolomite.
