Abstract

In mushroom cultivation of white oyster mushroom (P. ostreatus), problems in the contamination during the production are typically found. This contamination is due to the issue in controlling temperature during the media sterilization for growing the fungus (bag-log). This suboptimal sterilization causes unwanted bacteria and spores to grow. To reduce the amount of contamination, the purpose of this study was to demonstrate and evaluate the temperature distribution using one convection pipe with diameter of 6 and 8 cm. The fuel used for this sterilization process is rice husk. Sterilization itself aims to kill other unwanted bacteria and spores on the bag-log. Sterilization was done by traditional steaming bag-log drums arranged in four rows upwards for 6 hours. Convection pipes were built in drums. The steamer was done by performing two retrievals of data. From the experiment results, the use of convection pipe of 8 cm was better than the convection pipe of 6 cm. This is shown from the amount of fungal contamination in convection pipes were less in 8. The result of temperature measurement using dual laser infrared thermometer was also completed and interpreted using Matrix Laboratory with interpolation method to get heat distribution result.

Abstract

The purpose of this study was to demonstrate an alternative solution as an insecticide from Indonesian natural ingredients. We investigated the potential use of Artocarpus altilis park (known as kluwih plants in Indonesia) for an anti-mosquito repellent because it contains flavonoids and saponins. The use of this type of insecticide is harmless, inexpensive, and largely available in Indonesia. In the experiment, we extracted bark and leaves of kluwih to obtain insecticidal material to repel Anopheles sp. To ensure the precise extraction and insecticidial effect, the experiments were conducted four times with three repetitions. For each experiment, we used 8.4 mL with the concentrations of 20, 30, and 40% of flavonoid. The results showed that the higher the concentrations of bark and leaf extracts of Artocarpus altilis park the higher the mortality rate of Anopheles sp is.
