Abstract

Penelitian ini merupakan penelitian yang memiliki tujuan untuk mengetahui Pengaruh Air Kelapa terhadap pertumbuhan tanaman bayam cabut (Amarutus Tricolor L) . Metode yang digunakan dalam penelitian ini adalah eksperimen . penelitian ini menggunakan desain Rancangan Acak Kelompo k (RAK) faktorial yang terdiri dari 5 perlakuan 4 ulangan yaitu, A0 = kontrol (tampa pemberian air kelapa), A1 = Pemberian 25 ml, A2 = pemberian 50 ml, A3 = pemberian75 ml, A4= pemberian 100 ml. data yang diamati adalah tinggi tanaman bayam minggu pertama dan minggu kedua. Berdasarkan hasil ananlisis di simpulkan bahwa Hasil analisis Univareate menunjukan pemberian air kelapa meberikan pengaruh yang sangat nyata terhadap pertumbuhan tinggi tanaman dan jumlah daun. Hal ini dilihat pada tinggi tanaman bayam (Amaruthus tricolor L) pada minggu I dengan nilai F hitung(70,919) lebih besar dari F tabel (3,06 dan sig (0,000) pada ɑ=0,05 (95%). Tinggi tanaman bayam (Amarathus Tricolor L) .pada minggu ke dua dengan nilai F hitung (23,449) lebi besar dari F tabel (3,06) dan sig (0,000) pada ɑ= 0,05 (95%). Dan jumlah daun tanaman bayam (Amaruthus Tricolor L) minggu I dengan nilai F hitung (9,563) lebih besar dari F tabel (0,02) Dan sig (0,000) pada ɑ=0,05 (95%), selanjutnya jumlah daun tanaman bayam (Amaruthus Trricolor L) minggu II dengan nilai F hitung (18,741) lebih besar dari F tabel (0,00) dan sig (0,000) pada ɑ=0,05(95%) .dari Hasil uji LSD (0,05) pada tinggi tanaman dan jumlah daun tanaman bayam menunjukan bahwa pemberian air kelapa dengan perlakuan A4 ( 100 ml ) memberikan dampak yang sangat nyata

Abstract

This study aims to analyze the water quality of the Anahoni river due to gold mining by covering chemical parameters (pH, DO, BOD, COD, heavy metal mercury (Hg), iron (Fe), copper (Cu), Cadmium (Cd), Arsenic (As) ) and cyanide (CN).Metal mercury, iron, copper, cadmium, arsenic, and cyanide were tested at the Proling Bogor Agricultural Institute (IPB) laboratory. Meanwhile, DO, BOD parameters were analyzed at the Maluku Provincial Health Office Laboratory. pH and temperature parameters were carried out measured in situ. The pH value of the waters was obtained in the range of 7.1-10.5.The measured DO concentration has a value that varies in the range of 4.6-10.4 mg/L.The concentration of BOD has a value in the range of 0.5-10 .25 mg/L. COD concentrations have values ​​in the range of 1.7-12.11 mg/L. Hg, Fe, Cu, As, and CN metals were detected in water and sediments.

Abstract

Kayeli Bay is a water in Buru Regency which has very important value in terms of ecological and economic functions. During its development, the ecosystem in Kayeli Bay bears the burden of pollution, especially heavy metal mercury as a result of the people's gold mining on Buru Island which uses Hg to get pure gold. Hg can accumulate in the environment, especially deposited in the sediments in Kayeli Bay waters. Mangrove plants that generally grow in estuary and coastal environments are a place for sediment accumulation. This plant has the ability to absorb and accumulate heavy metals, one of which is R. mucronata. This study aims to analyze the concentration of heavy metal Hg in mangroves of R. mucronata and sediments, and to analyze the bioaccumulation of heavy metal Hg in R. mucronata in Kayeli Bay, Buru Regency. Samples were taken from 3 stations, namely the Anahoni River Estuary (Station I), the Wailata River Estuary (II Station) and the Waeapo River Estuary (III Station). Each station has 2 sampling points (replicates). Determination of the concentration of Hg metal in the sample using the CV AAS method. The average value of Hg concentration in the roots was higher than the bark and leaves of the mangrove R. mucronata, but the concentration was lower than the sediment and was still below the critical value of Hg for plants. The average value of sediment Hg concentration is still below the sediment quality standard. In this study, R. mucronata mangroves were excluder and phytostabilized, where there was a limitation on the absorption of heavy metal Hg from water and sediment and the most Hg accumulation was found in the roots.
