The phytoremediation potential of H. salsugineum was evaluated. In addition, the benefit cost (B/C) analysis was performed for its potential use in phytoremediation. The plant and soil samples were collected from Eskil and Cihanbeyli between May and September in 2016. A total of 300 soil and plant samples were analysed for heavy metal content. Statistical and standard benefit/cost analyses were performed for assessment. The capacity of accumulating the aforementioned heavy metals was found to be high in H. salsugineum. It was found that Ni and Pb ratio exceeded optimum values in its habitat, and H. salsugineum accumulated available Ni and Pb. When the plant was evaluated in terms of benefit/cost, B/C ratio was greater than 1 during the useful life of the study. This conclusion increases the ecological and economical values of H. Salsugineum, effecting its potential use in phytoremediation.Dalam kajian ini, Hypericum salsugineum, sejenis tumbuhan halofit endemik yang tumbuh di sekitar Tasik Garam telah dianalisis untuk menentukan kandungan logam berat (kromium, plumbum, kuprum, zink dan nikel) padanya dan pada tanah tempat ia tumbuh. Potensi fitopemulihan H. salsugineum juga telah dinilai. Selain itu, analisis nisbah faedah/kos (F/K) telah dilakukan untuk potensi kegunaan dalam fitopemulihan. Sampel tumbuhan dan tanah telah dikumpul daripada Eskil dan Cihanbeyli antara Mei dan September 2016. Sejumlah 300 sampel-sampel tanah dan tumbuhan telah dianalisis untuk kandungan logam berat. Analisis statistik dan analisis Piawai Faedah/Kos telah dilakukan sebagai penaksiran. Kapasiti pengumpulan logam berat tersebut telah diperoleh dalam jumlah yang tinggi di dalam H. salsugineum. Nisbah Ni dan Pb didapati telah melebihi nilai optimum dalam habitat dan kandungan yang dikumpul daripada H. salsugineum. Apabila tumbuhan ini dinilai berdasarkan faedah/kos, nisbah (F/K) telah menunjukkan nilai yang lebih besar daripada 1 sepanjang kajian dijalankan. Rumusan ini menambah nilai ekologi dan ekonomi H. salsugineum, yang seterusnya memberi kesan kepada potensinya untuk digunakan dalam fitopemulihan.eninfo:eu-repo/semantics/openAccessEconomic Value AnalysisHalophyteHypericum SalsugineumPhytoremediationSalt LakeKata KunciAnalisis Nilai EkonomiFitopemulihanHalofitHypericum SalsugineumArticle50123493350310.17576/jsm-2021-5012-03Q2
