Abstract

This study aimed to analyze the factors that influence the demand for rubber, as well as to analyze demand response for rubber in Jambi Province. This research is using simultaneous equations through 3 Stage Least Square (3 SLS) estimation method. The result showed that factors influence the demand for rubber in Jambi is bokar prices, demand for rubber in South Sumatra, Indonesia rubber consumption, the price of synthetic rubber and rubber demand in Jambi at the prior period. While the response of demand for rubber in Jambi is inelastic as changing all the explanatory variables in the short term and long term.

Abstract

The study on the solubility of calcium kidney stone in the ethyl acetate and water fraction of Duduk leaves was intended to investigate the efectiveness of the kidney stone solubility. The kidney stone was obtained after surgery, and analyzed applaying the infrared spectrophotometer to identify qualitatively the type of kidney stone. The study was performed by dissolving the calcium kidney stone 100 mg in 10 ml fraction of ethyl acetate and water Duduk leaves respectively. The mixtures were shaken and incubated at 370C for 4 hours in a waterbath and were then filtered. The solubility of calcium was determined by the rapid neutron activation tehnique. The result indicated that calcium solubilitty in the water fraction was better than that in the ethyl acetate fraction.
