Abstract

Nyamplung oil originated from Ujong Pancu, Aceh Besar is one of the vegetable oil sources which is not fully utilized yet. The extraction of nyamplung oil is done using soxhletation with n-hexane solvent; during this process, the oils produced is at the 55.55% levels. The product is in the form of yellowish green liquid with the density of 0.88gr/ml. The nyamplung oil extract has the iodine number of iod 83.53 mg iod/g and hydroxyl number of  64.292 mg KOH/gram which can be utilized as the raw material in making polyurethane membrane. Polyurethane membrane is synthesized by reacting fatty acids from nyamplung seed oil with hexamethylene-1.6-diisocyanate (HDMI). The ration of the oil towards HDMI is variated as, 5:1;5:3;5:5;5:7;5:9 v/w. The membrane has a composition of  5:7 v/w  with 90-100 oC polymerization temperatures and  160oC curring temperature for 8 hours is hard, homogenous and quite elastic with a transparent brown colour.

Abstract

Kecombrang plant (Etlingera eliator (Jack) R.M. Smith), has bioactive compounds of polyphenols, alkaloids, flavonoids, steroids, saponins and essential oils. The purpose of this study, to make a cream scrub formulation from ethanol extract of kecombrang flowers that meets the standards and benefits on the skin. The method of this study, by varying the concentration of ethanol extract of kecombrang flowers 5% and 10% with modified formulations adding amylum oryzae as a scrub and without the addition of amyulum oryzae. The results of the 28-day study based on the parameters, in the organoleptical test had a stable shape, odor, and color, in the homogeneity test showed a homogeneous preparation, the pH test had a stable value of 7, the spreadability test had an average value of 5 cm, stable results in room or low temperature storage (2-8oC). Hedonic test results with parameters, aroma, texture, color, and effectiveness, namely formulation I 10% with an average scale value of 5, which means very like is a formulation with the addition of amylum oryzae as a scrub. Formulation results with the addition of amylum oryzae affect the preparation of abrasive formulations. The results of the skin effectiveness test, in the moisture test using a skin analyzer with an average value of moist volunteer skin at week 4, and the volunteer's skin color is slightly brighter. In conclusion, the cream scrub formulation has a good formulation, kecombrang flower extract has the effect of brightening the skin and moisturizing the skin.

Abstract

Heavy metal contamination of traditional herbal medicine (jamu) is a threat to humans, especially at levels above known threshold concentrations. Traditional herbal medicine found in Banda Aceh City – Indonesia, polluted by heavy metals cadmium (Cd), lead (Pb), and mercury (Hg) was performed. Heavy metal analysis used Flame - Atomic Absorption Spectrometry (FAAS) and Chemical Vapor Generation - Atomic Absorption Spectrometry (CVG - AAS) methods. The validation of the method was performed to obtain more accurate heavy metal analysis results for the samples. Heavy metal contamination, especially Pb metal, with concentrations of 4.32 ± 0.14 mg/Kg to 29.25 ± 0.24 mg/Kg. The Cd metal contamination was only found in herbal medicine sample E with a concentration of 0.80 ± 0.02 mg/Kg, above the threshold. The Hg metal contamination was also found with concentrations of 0.20 ± 0.01 to 2.14 ± 0.06 mg/Kg, and some were not detected. The government should be very concerned about stopping the distribution of herbal medicine that can be harmful to health and should inspect drug stores that still sell herbs that do not have established standards.
