Abstract

Banana peel consists of nitrogen atoms, sulfur and organic materials such as carboxylic acids that can function to bind pollutant molecules. The purpose of this research is to make King Banana (Musa acuminate) peel as filtration media to improve the physical quality of water including water clarity, pH value, TDS and Dissolved Oxygen (DO). There are three stages carried out, including preparation of banana peel waste, adjusting the media and filtration time and data analysis. The preparation process of banana peel waste is done by cleaning the banana peel then dried and mashed, then alkalized using 0.5 N NaOH. Then a variation in the amount of filtration media is made, namely: 60 g, 80 g and 100 g of plantain peels formulated using an additional 30 grams of zeolite with variations in filtration time, namely: 3 hours, 6 hours and 9 hours. The filtration results obtained using a variation of 100 grams of filtration media with a filtration time of 9 hours is the best media combination where the results obtained show an increase in water clarity, pH 5.41 and an increase in DO (Dissolve oxygen) of 20.

Abstract

The sublethal effect of Blatella germanica infected with Metarhizium anisopliae, Beauvaria bassianna, and Spicaria on its offspring has been carried out. It is known that the LC50 value of each fungus is 106. This study aims to determine the extent of the sublethal effect on the duration of ootheca formation, the number of ootheca, and the number of ootheca produced. The ‘Dipping method’ was used with three treatments and five replications. The results showed that the sub-lethal effect influenced the duration of ootheca formation. Metarhizium anisopliae and Beauveria bassiana affected the start of ootheca formation when compared to the control (25.95 days), the length of time needed for ootheca that produced nymphs in Metarhizium anisopliae and Beauveria bassiana exposure compared to the control (6 days) and the number of nymphs caused by Metarhizium anisopliae and Beauveria bassiana produced fewer nymphs than the control (29.25 days).
