Abstract

Peat water is identical with low acidity (pH), iron (Fe2+), manganese (Mn2+) and has a high color, making it difficult to treat it by filtering. From the results of batch and continuous processing using quicklime (CaO) and aluminum sulfate (Al2 (SO4)318 H2O) it was found that the levels of iron and manganese decreased significantly. For the batch process, iron decreased from 3.5 ppm to 0.1 ppm (97%), manganese from 0.59 ppm to 0 ppm (100%), color from 130 tcu to 1.7 tcu, while for turbidity there was a decrease from 33.8 ntu to 1.9 ntu, pH increased from 3.19 to 6.8. While in the continuous process with the same dose, iron decreased from 3.35 ppm to 0.05 ppm (98.6%), manganese from 0.5 ppm to 0 ppm (100%), pH increased from 3.19 to 7.16 while the turbidity of water decreased from 31.8 ntu to 1.14 ntu. The results of this peat water treatment meet the quality standard of the Minister of Health No. 32 of 2017. Based on the results of the research conducted, it is necessary to apply the results of the research that has been done to peat water in the Talang Sacred area and how processing technology and innovative products are processing peat water into drinkable water for peoples at Talang Keramat, Banyuasin Regency, South Sumatra

Abstract

This study aimed to analyze several secondary metabolite compounds that are antioxidants in the leaves of gaharu plants based on the position of the leaves on the branches. The experimental design used was a non-factorial randomized block design. The research treatment consisted of three factors, namely (A1) young leaves (position of 1-4 leaves from the shoot), (A2) medium leaves (position of 5-8 leaves from the shoot), and (A3) old leaves (position of 9-12 leaves from the shoots). The results showed that the position of the leaves on the branch of the gaharu plant significantly affected the number of secondary metabolites produced. Gaharu plant leaves contain secondary metabolites, namely alkaloids 1.65-4.20%, saponins 2.47-4.00%, tannins 0.69-2.70%, total phenol 29.70-54.68 mg/L, and total chlorophyll 9.21-20.03 mg/L. Tannins and total phenols are functional compounds in gaharu leaves which are antioxidants. The antioxidant properties of this leaf are included in the strong category with an IC50 value of 49.30-68.30 mg/L wherein young leaves have higher antioxidant properties than old leaves.
