FORMULASI SEDIAAN KRIM TABIR SURYA DARI EKSTRAK ETANOL BIJI BUAH ALPUKAT (Persea americana Mill.)

Summary

This research proposal explores the formulation of sunscreen cream using ethanol extract from avocado seeds (Persea Americana Mill). The study aims to investigate whether avocado seed extract can be used as an effective sunscreen due to its antioxidant properties, which help combat UV-induced skin damage. The researcher evaluates various concentrations of avocado seed ethanol extract (0.5%, 1%, and 1.5%) and their impact on the sunscreen's physical quality, SPF value, and antioxidant activity. The proposal also outlines the formulation process, testing methods, and evaluation criteria, including organoleptic tests, viscosity, stability, and safety measures.

Takeaways

• 😀 The research proposal aims to formulate a sunscreen cream using ethanol extract from avocado seeds (Persea americana Mill).
• 😀 Skin is the outermost organ exposed to UV radiation, leading to potential problems like wrinkles, skin aging, burns, and skin cancer.
• 😀 Sunscreens with an SPF of at least 30 are recommended to protect the skin from harmful UV radiation.
• 😀 Avocado seeds, typically discarded, contain flavonoids with antioxidant properties that can help counteract free radicals from UV radiation.
• 😀 The study explores whether avocado seed extract can be formulated into a sunscreen and the effect of varying concentrations on the product's efficacy.

Q & A

What is the main goal of this research proposal?

The main goal of the research proposal is to formulate a sunscreen cream from ethanol extract of avocado seeds (Persea Americana), utilizing its antioxidant properties to protect the skin from UV radiation.

What are the skin-related issues caused by excessive UV radiation, as mentioned in the script?

Excessive UV radiation can cause wrinkles, black spots, premature aging, skin cracking, burns, and in severe cases, it can lead to skin cancer and eye damage.

Why is sunscreen considered important for skin health?

Sunscreen is important because it protects the skin from harmful UV radiation, which can cause skin damage, premature aging, and increase the risk of skin cancer.

What is the significance of the SPF value in sunscreen?

The SPF (Sun Protection Factor) indicates how well a sunscreen can protect the skin from UV radiation. A higher SPF means longer protection, with values above 30 providing more effective defense.

How does avocado seed extract contribute to the formulation of sunscreen?

Avocado seed extract contains flavonoids, which have antioxidant activity. These antioxidants help neutralize free radicals caused by UV radiation, making avocado seed extract useful in sunscreen formulations.

What are the two research hypotheses proposed in the study?

The first hypothesis is that avocado seed extract can be formulated into sunscreen preparations. The second hypothesis is that sunscreen creams containing avocado seed extract will have effective antioxidant activity and can protect the skin from UV radiation.

What are the independent and dependent variables in this research design?

The independent variable is the concentration of avocado seed ethanol extract (0.5%, 1%, and 1.5%). The dependent variables include the physical quality of the cream, safety, and SPF value.

What methods are used for extracting avocado seed ethanol in this study?

The extraction method used is maceration, where dried avocado seeds are submerged in ethanol (96%) for 24-hour intervals, repeated three times. The resulting extract is combined and evaporated to yield a thick extract.

How will the SPF value of the sunscreen be measured?

The SPF value will be determined using a UV-Vis spectrophotometer. The extract will be diluted and the absorbance measured at wavelengths between 290 and 326 nm, which will be used to calculate the SPF value.

What physical properties of the sunscreen cream will be evaluated?

The sunscreen cream will be evaluated for its organoleptic properties (color, aroma, texture), homogeneity, pH, adhesion, viscosity, stability (under different temperatures), spreadability, and centrifuge test to assess the overall quality.
