Abstract

Torch ginger (Etlingera elatior) is a herbaceous plant from Southeast Asia, traditionally used as herbal medicine by local people due to its antibacterial, antiviral, anti-inflammatory, anti-allergic, antioxidant, and anti-cancer properties. Despite its various benefits, this plant has struggled to enter the market because it has not been cultivated on a large scale. Therefore, the opportunity for commercial cultivation of this plant remains wide open. Tuban Regency is a potential agricultural district in Java, strategically positioned on the main road between Central Java Province and East Java Province. Unfortunately, little research has been conducted on land suitability evaluation in Tuban Regency’s agricultural areas. This research aimed to evaluate land suitability for torch ginger cultivation in Tuban Regency. Based on the studies conducted, agricultural land in Tuban Regency is quite fertile, but adequate irrigation is necessary to help the plants survive during the dry season. Torch ginger naturally grows in densely vegetated areas with sufficient water availability. Therefore, cultivating torch ginger in Tuban requires several special treatments, such as maintaining water availability, providing shade and mulch to regulate temperature and humidity, applying phosphorus and organic fertilizers to address phosphorus fixation in limestone soil, and using growth regulators like paclobutrazol to overcome flowering inhibition. From the various literature that has been studied, it was found that the land in the Northern Limestone Mountains of Tuban Regency, is quite fertile and suitable for agricultural land.

Abstract

Laela, F., & Ammurabi, S.D. (2024). Utilization of Ornamental Plants as Phytoremediation Agents to Reduce Lead (Pb) Contamination in Urban Area. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 48–58).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Lead (Pb) is one of common heavy metal pollutant that produced from human activities. Lead pollution produced from fuel, mining activities, fertilizer, pesticides application, and industrial activities that contribute to urban pollution level. Lead concentration in soil cause health problems such as digestive disorders, kidney disease, anemia, and decrease of intelligent quotient (IQ) score. High concentration of blood lead level caused negative health impacts such as increase of cardiovascular diseases, kidney failure, blood anemia, loss of vision, and  bones impair development. Recent science development has given us several alternatives to reduce lead contamination in water and soil, one of which is phytoremediation. Phytoremediation is a process of soil and water decontamination from hazardous substances with plants. Ornamental plants become alternative method of lead phytoremediation because it is unconsumed by human and animals as well as served decorative function. In this paper, various ornamental plant species that show a high capacity to tolerate, accumulate, and improve contaminated soil of lead will be described. Plants with lead phytoremediaton abilities could become solution for urban green space utilization in Indonesia. The purpose of this paper was to determine the types of ornamental plants that can be used as phytoremediators for lead (Pb) contamination in urban areas and to determine the mechanism process.
