Abstract

The issue of environmental pollution has become a concern, especially for the government, since the establishment of Law No. 4 of 1982. This is because the effects of pollution can be toxic and even fatal for living beings, particularly humans. One of the pollutants in the environment generated from mining industry waste is heavy metal Fe. In light of these problems, a study was conducted to investigate the effectiveness of sawdust and Moringa twigs as by-products in adsorbing heavy metal iron (Fe) in the liquid waste of the gold mining industry. This research is classified as pure experimental research. The research reveals that the mean percentage reduction in the heavy metal iron (Fe) content in the gold mining industry wastewater, after treatment with the addition of Moringa leaf powder, is 9.6%. On the other hand, treatment with the addition of Moringa stem powder achieves a reduction of 92%. This significant difference is attributed to the bioactive compound rhamnosyloxy-benzyl isothiocyanate present in Moringa. This compound has the ability to adsorb and neutralize sludge and metal particles found in the waste suspension, along with dirt particles in the water. Consequently, Moringa shows potential as a natural coagulant for water purification purposes.

Abstract

The skin is the largest organ on the human body that plays a vital role in protecting the body from environmental aggressions and maintaining internal balance, however, the natural aging process and exposure to external factors can cause various skin problems, including loss of elasticity, fine lines, and hyperpigmentation. To address these issues, the development of skincare products such as anti-aging gels is important. The aim of this study was to optimise the base of the anti-aging gel formulation by considering the selection of gelling agents with appropriate variations.The research method was conducted by obtaining five different formulas using a combination of gelling agents Carbopol and CMC Na with variations of Formula 1 which is 1% b/v carbopol with 2% b/v CMC Na, Formula 2 which is 1.25% b/v carbopol with 1.75% b/v CMC Na, Formula 3 which is 1.5% b/v carbopol with 1.5% b/v CMC Na, Formula 4 which is 1.75% b/v carbopol with 1.25% b/v CMC Na and Formula 5 which is 2% b/v carbopol with 1% b/v CMC Na . Physical testing was conducted to evaluate the formulation characteristics, including colourimetry, pH, viscosity, adhesion, and spreadability, comparisons between different formulas were conducted to determine the best base formula. The results showed that formula 5 with the ratio of gelling agent carbomer 2% b/v and CMC Na 1% b/v, is the optimal formula supported by physical testing, namely the metric choleretic test is good, homogeneous, pH 6.237 in accordance with the pH range of the skin, the Viscosity test has the highest viscosity of 148.34 d.Pas, the longest adhesion test with an adhesion time of 9.535 seconds, allowing the active substance to more easily penetrate the skin and be absorbed.
