Pola asupan kromium dari konsumsi beras pada 3 kelurahan berkisar 0-1909 µg/hari dengan nilai rerata sebesar 971 µg/hari. Nilai rerata pola asupan kromium di 3 kelurahan jauh melewati batas aman yang ditetapkan oleh WHO sebesar 320 µg/hari. Dari perhitungan risiko kesehatan, diperoleh hasil nilai Risk Quotient untuk kelurahan desa Canden, Trimulyo, Sumberagung secara berurutan sebesar 3,00, 2,00, 2,00. Nilai RQ pada 3 kelurahan diatas batas aman yang ditetapkan oleh WHO sebesar RQ > 1. Berdasarkan perhitungan risiko terjadinya kanker, dilihat dari nilai ECR diperoleh hasil berkisar1,E-01 – 2,E-01, nilai ECR ini jauh melewati batas aman yang ditetapkan oleh WHO sebesar 10-4. Konsentrasi kromium, laju asupan harian, pola konsumsi, karakteristik responden berpengaruh terhadap risiko kesehatan. Kata kunci: Kromium Heksavalen, Beras, Analisa Risiko Kesehatan

Abstract

Livistona is one of the genera of palm plants with a wide distribution area, ecologically diverse and of horticultural, economic and ecological importance. The Livistona genus is an important ornamental plant species for landscapes, and generally tolerates it as an indoor (Siregar, 2005). The purpose of this study was to determine the ecology of Serdang (Livistona sp.) in Sekernan District and Mendahara Ulu District. This research was conducted in SeptemberOctober 2021 based on the purposive sampling method. The results obtained are Serdang ecology (Livistona sp.) Sekernan and Mendahara Ulu subdistricts found 16 serdang individuals, the composition of vegetation at the study site for tree stadia population was only slightly in secondary forest cover found 8 species of trees, while for oil palm plantations/rubber plantations there were 5 tree species, for the pole level most were found in oil palm plantations/rubber plantations with a total of 5 species while in secondary forest only 3 species, the sapling level was mostly found in oil palm plantations/rubber plantations because in rubber plantations the community allowed their gardens to be grown other than rubber, the seedling rate was mostly found in oil palm/rubber plantations with a total of 29 species with 129 individuals compared to secondary forests. Ecological factors around the herbaceous plants for humidity range from 250C–310C. The condition of the soil at the research site is sandy soil with a pH of 4.00 – 5.06. The slope of the medium-growing area is between 8% to 21%, which means that the herbaceous plant grows on the slope of the sloping to moderately steep area. Keywords: Livistona, Vegetation, Ecological Factors   Abstrak Livistona adalah salah satu dari marga tumbuhan palma yang wilayah penyebarannya lebar, ekologinya beragam dan bernilai penting secara hortikultura, ekonomi dan ekologi. Livistona adalah jenis tumbuhan hias yang penting untuk landskap, dan umumnya toleransi sebagai tanaman dalam ruang (Siregar, 2005). Tujuan penelitian ini mengetahui ekologi serdang (Livistona sp.) di Kecamatan Sekernan dan Kecamatan Mendahara Ulu. Penelitian dilaksanakan pada bulan September-Oktober 2021 berdasarkan metode purposive sampling. Hasil penelitian ekologi serdang (Livistona sp.) Kecamatan Sekernan dan Kecamatan Mendahara Ulu ditemukan 16 individu serdang, Komposisi vegetasi dilokasi penelitian stadia pohon populasinya hanya sedikit pada tutupan hutan sekunder ditemukan 8 spesies pohon, sedangkan untuk kebun sawit/kebun karet terdapat 5 spesies pohon, tingkat tiang paling banyak ditemukan di tutupan kebun sawit/kebun karet dengan jumlah 5 spesies sedangkan di hutan sekunder hanya 3 spesies, tingkat pancang banyak di temukan pada tutupan kebun sawit/kebun karet karena pada kebun karet masyarakat membiarkan kebunnya ditumbuhan selain karet, tingkat semai banyak ditemukan di kebun sawit/kebun karet dengan jumlah 29 spesies dengan individu 129 dibandingkan hutan sekunder. Faktor ekologi di sekitar tumbuhan serdang kelembaban berkisar 250C–310C. Keadaan tanah di lokasi penelitian yaitu tanah berpasir dengan pH 4.00 – 5.06. Kemiringan tempat tumbuh serdang antara 8% hingga 21% bearti tumbuhan serdang tumbuh di kemiringan tempat landai hingga agam curam. Kata kunci: Livistona, Vegetasi, Faktor Ekologi
