Title

EFISIENSI PENYERAPAN LOGAM Pb2+ DENGAN MENGGUNAKAN CAMPURAN BENTONIT DAN ENCENG GONDOK M Faisal

Adsorption of Pb2+by using a mix of bentonite and water hyacinth has been carried out in a bacth system. The purpose of the research is to investigate the abilty of the mix bentonite and water hyacinth to adsorp Pb2+. Prior to adsorption process, the mix of bentonite and water hyacnth was activated physcally by H2SO4. The adsorption ability between activated-adsorbend and without activated-adsorbend was then compared. In the activaved process, the mix of bentonite and water hyacinth used was 4 gram in weight and 120 ml of H2SO4 1,2 M. In this research, adsorption time of 30, 60, 120 menit, the speed of 50, 100, 150 rpm and the Pb2+concentration of 30, 35 and 40 mg/l were used. The result showed that the adsorption efficiency of activated-adsorbend is higher than that of without activaved. The maximum adsorption of 0,987 mg/g were obtained at Pb2+concentration of 40 mg/l with a contact time and speed of 120 min and 150 rpm, respetively.

This research is a preliminary study of the utilization of chitosan modified with liquid smoke to produce edible coating material that can be used as a preservative of beef. Chitosan compounds obtained from shrimp shell waste, while liquid smoke produced from pyrolysis of palm shells at a temperature of 340oC. Edible coating solution with various concentrations was made by dissolving chitosan (1-1.5%) into 3% liquid smoke, which was then applied as a meat preservative. Meat samples that have been dipped edible coating for 15 minutes, then stored in the refrigerator and observed decreased endurance every 24 hours for 8 days. Analysis results of Gas Chromatography-Mass Spectrometry (GC-MS) showed that liquid smoke contains phenol and acetic acid compounds that have antimocrobial properties. Meat endurance test was done by analyzing the aroma, texture and color of meat. The results showed that the beef that has been coated liquid chitosan solution can last up to 7 days. Chitosan concentration affects the endurance of meat, the greater the chitosan concentration, the better the meat endurance. The optimum concentration was obtained at 1% of chitosan, the meat still has an acceptable aroma, texture and color for up to 6 days. This suggests that chitosan-liquid smoke can be used as an edible coating material.
