Abstract

Breast cancer is the second largest number of cancer cases in Indonesia, after cervical cancer. The growth of these cancer cells can be prevented with compounds Pentagamavunon-0 (PGV-0) and Pentagamavunon-1 (PGV-1). This compound is an analog of curcumin compounds that have anti breast cancer activity. Modeling the structure of compound PGV-0 and PGV-1 through computational chemistry methods Ab-initio HF/4-31G could be used to predict the geometry and structure elucidation spectra associated with pharmacological activity such as anticancer compounds theoretically.This research involves modeling the structures and spectra prediction calculation compounds PGV-0 and PGV-1 by computational chemistry methods Ab-initio HF/4-31G, using Gaussian03W. The result using Ab-initio HF/4-31G method then compared with data from experimental geometry and the results of calculations with AM1.The results showed that computational chemistry methods Ab-initio HF/4-31G calculations give better results for modeling the structure compared semiempirik method AM1.

Abstract

Lignin was a component of wood and always eliminated by chemical processing in many industries. On the other hand, oil palm bunches were the waste of palm oil industry, where that also containing high lignin.This study used lignin from residual waste of palm oil industry as biomass to adsorb silver (Ag) and copper (Cu) metal that is contained in electroplating waste by looking at lignin mass ratio, temperature and time in order to obtain optimal adsorption condition. The mass variations used were 100 mg, 200 mg, 300 mg, 400 mg, and 500 mg. While for the variation of contact time were 2 hours, 3 hours, 4 hours, 5 hours, 6 hours. For temperature variations were 30 °C, 40 °C, 50 °C,   and  60 °C.The results showed that the most optimal lignin mass ratio in adsorbing silver and copper metals was 200 mg/ 50 mL. While the most optimal contact time were 4 hours for Ag and 2 hours for Cu. For the most optimum temperature in adsorbing Ag metal at 50 °C and for Cu metal at 30 °C.
