Abstract

Papaya fruit is one source of vegetable protein. This fruit is often cultivated because of its considerable benefits for health. In addition to cultivating papaya plants, farmers also often ripening papaya fruit that has been harvested using ethrel solution. This study aims to describe the effect of The Addition of ethrel solution on the quality of papaya fruit. This research is an experimental study consisting of 5 treatments and 3 replications with a test model that is an organoleptic test to measure the quality of papaya fruit. Research data presented descriptively. The results showed that administration of Ethrel solution affected the quality of papaya fruit with optimal concentration in the treatment of P3 or 0.6% Ethrel per liter of water. Papaya fruit has the best color, texture, and taste in the P3 treatment when compared with the P0, P1, P2, P4, and P5 treatments. The best length of days in the ripening process is five days.

Abstract

Jackfruit skin often considered as by product immediately after the fruit being used or consumed. However, if processed further this jackfruit skin can actually be fermented and has the potential to be a biofuel. Traditionally wastewater from fermented jackfruit skin can produce bioethanol. Bioethanol is ethanol (ethyl alcohol) whose production process uses natural raw materials and biological processes. Considering the current condition, namely fossil fuels in Indonesia are getting scarce, especially motor vehicle fuel, so naturally this bioethanol from fermented jackfruit skin has the opportunity to become a substitute energy. This study aimed to determine the ethanol content of jackfruit skin fermentation. Anaerobic fermentation was done with the addition of 600 ofater and one month incubation. The resulting bioethanol levels were measured with an alcohol meter. The results showed that different levels of salt produced an amount of ethanol which was also different from the fermentation of jackfruit skin. The difference in the amount of ethanol produced is thought to be due to the influence of the growth of lactic acid bacteria.
