G-LOG #BK3.3 Praktikum Biokimia 'Pengamatan Ekoenzim Kulit Nanas'

Summary

This video demonstrates the process of making ekoenzim, a natural fermentation product made from organic waste like pineapple peels and sugar. The video compares two types of sugar—brown sugar and white sugar—to see how they affect the ekoenzim. The process involves mixing sugar, water, and pineapple peel, followed by fermentation for three months. Various tests are conducted to analyze the ekoenzim’s pH, dissolved solids, color, and aroma. Ekoenzim serves as a versatile, eco-friendly cleaner and agricultural enhancer, improving soil health and pest control.

Takeaways

• 😀 The introduction highlights the concept of ekoenzym, a fermentation product made from organic waste, sugar, and water.
• 😀 Ekoenzym was conceived by Dr. Sutan Pun Wong, a founder of an organic farming association in Thailand.
• 😀 The primary use of ekoenzym is as an eco-friendly floor cleaner and detergent replacement, beneficial for agriculture, animal husbandry, and the environment.
• 😀 In agriculture, ekoenzym is used to improve soil fertility, eliminate pests, and enhance the quality of crops.
• 😀 To create ekoenzym, a mix of sugar (either brown or white) and pineapple skin (150 grams) is fermented for three months.
• 😀 The ingredients used include 50 grams of sugar (both brown and white) and 500 ml of water, which are combined and mixed before adding the pineapple skin.
• 😀 Two experiments are conducted: one with white sugar and one with brown sugar, to compare their effects.
• 😀 The mixture is shaken to ensure homogeneity, and the process continues with fermentation in bottles.
• 😀 During fermentation, the bottles need to be opened daily to release gas produced by the fermentation process.
• 😀 The key observations in the experiment include measuring pH, total dissolved solids (TDS), color, aroma, and the appearance of the final ekoenzym product.
• 😀 The appearance of the ekoenzym is noted to have a slight turbidity, with the brown sugar variant appearing more brown and murky compared to the white sugar variant.

Q & A

What is the primary purpose of making ecoenzymes in this experiment?

The primary purpose is to create an eco-friendly cleaning product that can be used in agriculture, livestock care, and general cleaning. It is made by fermenting organic waste, such as pineapple peels, with sugar and water.

What are the two types of sugar used in the experiment?

The two types of sugar used are brown sugar and white sugar.

Why is it important to shake the mixture after adding the ingredients?

Shaking the mixture ensures that all the ingredients, including the sugar and pineapple peel, are evenly distributed and properly dissolved, helping the fermentation process.

How long should the ecoenzyme mixture be left to ferment?

The ecoenzyme mixture should be left to ferment for three months.

What regular maintenance is required during the fermentation process?

The bottles should be opened once a day to release the gas produced during fermentation, which helps prevent the bottle from exploding due to built-up pressure.

What measurements and tests are conducted on the ecoenzyme?

The ecoenzyme is tested for pH, total dissolved solids (TDS), color, aroma, and appearance.

What tools are used to measure the pH and TDS of the ecoenzyme?

A pH meter is used to measure the pH, and a refractometer is used to measure the total dissolved solids (TDS).

What was observed about the color of the ecoenzyme mixtures?

The ecoenzyme made with brown sugar has a murkier, brown color, while the one made with white sugar has a slightly lighter, also brownish, but less murky appearance.

What does the ecoenzyme smell like during the observation?

The ecoenzyme has a fermented smell with a hint of pineapple fragrance.

Was there any foam observed in the ecoenzyme mixtures during the experiment?

No foam was observed on the surface or at the bottom of the ecoenzyme mixtures made from both brown and white sugar.
