Abstract

This research on Analysis of the content of Sulphur dioxide (SO2) accumulated in Pitchelobium dulce and Terminalia catappa Leaves had been carried out in PT. KIMA of Makassar. The research is aimed at identifying the alloys of Sulphur diokside (SO2) accumulated in Pitchelobium dulce and Terminalia catappa leaves in PT. KIMA, Makassar. The analysis of SO2 content was carried by using of ash analisys was applied to Spectronic -20.  The results of the research suggested for accumulated Sulphur dioxide (SO2), the highest average concentration occurred in west sector with 2,80% for Pitchelobium dulce and 1,60% for Terminalia catappa leaves, whereas the lowest average concentration occurred in the north sector with 0,85% for Pitchelobium dulce leaves and with 0,63% for Terminalia catappa leaves. The capacity of these tho kinds of plants in absorbsing and accumulating pollutans in substantial number with out inducing any physiological change until tha plants died constituted imperortant information, especially in attempt to solve the problem of air pollution occurred in industrial area.   Keywords : SO2, concentration, plant, Pitchelobium dulce, Terminalia catappa.

Abstract

ABSTRACTThis study aims to evaluate the effect of fertilization and different light intensity on secondary metabolite synthesis of bitter plant (Andrographis paniculata Ness) and the ideal harvest age to obtain the highest levels of secondary metabolites. The study was conducted using Completely Randomized Design (CRD) with factorial 3 x 3. The main factor is fertilization treatment which consist of three levels : NPK (Urea 1.2 grams / plant, TSP 2.4 g / plant and KCl 0.6 g / plant), animal manure (1.2 kg / plant) and without fertilization. The second factor is the different light intensity which consist of three levels: full light intensity, half-shade and full shade. For Each treatment combination 3 replicates were used. Measurement of levels of secondary me tabolites by HPTLC method based on the dry weight of 50 mg / plant for each treatment combination. Data were analyzed using the Analysis Of Variance (ANOVA).The results obtained showed that bitter plant response differently to fertilization and different light intensity on secondary metabolite synthesis. Light intensity effected the synthesis of secondary metabolite of bitter plant, if the harvest was conducted at of 1 month after planting, the highest levels found on NPK fertilizer or without fertilizer with light intensity 100%. When the plants were harvested at 2 months after planting There was no effect of light intensity in all treatment combinations.Keywords : Secondary metabolites, fertilizers, light intensity
