Takeaways

• 😀 Cengkeh (clove) is an important Indonesian plant with global recognition and various health benefits.
• 😀 Clove can be used for cooking, strengthening bones, treating stomach ulcers, and even enhancing eyebrow color.
• 😀 Clove oil, extracted from clove, has benefits like relieving headaches, treating skin problems, and reducing acne.
• 😀 The goal of this practical experiment is to isolate clove oil through Stahl distillation, increasing its economic value.
• 😀 Stahl distillation is a method for separating compounds based on boiling points, ensuring higher purity by keeping the distillate free from air contact.
• 😀 Fresh cloves are priced at 35,000 IDR per kg, while dried cloves are worth 95,000 IDR per kg. Clove oil can be sold for 30,000 IDR per ml.
• 😀 The purity of the extracted clove oil directly affects its market price, with higher purity leading to higher prices.
• 😀 The experiment involves using 20 grams of dried clove buds, which are ground to increase surface area for efficient extraction.
• 😀 After extracting the clove oil using Stahl distillation, the product is analyzed for its purity using a refractometer to measure the refractive index.
• 😀 The final result from the experiment produced 1.2 mL of clove oil with a yellow color and a refractive index of 1.5345, indicating its purity.

Q & A

What is the main objective of the experiment demonstrated in the video?

The main objective of the experiment is to isolate clove oil using steam distillation (Destilasi Stahl) to increase its economic value and learn about the separation of compounds based on differences in boiling points.

What is the significance of using steam distillation in this experiment?

Steam distillation is used because it ensures that the extracted oil does not come into direct contact with air, maintaining higher purity, which increases the value of the final product.

How does the purity of the clove oil affect its market value?

The purity of clove oil directly affects its price. Higher purity results in a higher price, with pure clove oil potentially selling for up to 30,000 IDR per milliliter.

What are the price differences between fresh, dried, and oil forms of cloves?

Fresh cloves are priced at 35,000 IDR per kilogram, dried cloves at 95,000 IDR per kilogram, and clove oil can be sold for 30,000 IDR per milliliter.

What materials and equipment are needed for this steam distillation experiment?

The materials and equipment needed include dried clove buds, a mortar, a round-bottom flask, distilled water, boiling stones, a distillation apparatus, an Erlenmeyer flask, sodium sulfate, and a refractometer.

What is the purpose of using boiling stones in the distillation process?

Boiling stones are added to the distillation flask to ensure even heating and prevent the sudden boiling of the liquid, which can cause the contents to splatter.

How is the separation of clove oil from water achieved after distillation?

The clove oil and water are separated by using a pipette to remove the water from the oil, leaving only the clove oil in the distillation flask.

What is the role of sodium sulfate in the experiment?

Sodium sulfate is added to the distilled oil to absorb any remaining water, ensuring that the oil is completely dry before being measured.

How is the purity of the clove oil measured in the experiment?

The purity of the clove oil is measured using a refractometer, which checks the index of refraction of the oil. A higher index of refraction indicates greater purity.

What was the final amount and characteristics of the clove oil produced in the experiment?

The experiment produced 1.2 mL of clove oil, which was clear and yellow in color with a distinct clove aroma.
