Effect of chitosan coating and bamboo FSC (fruit storage chamber) to expand banana shelf life

Chitosan has been widely used as fruit preserver and proven to extend the shelf life of many fruits, such as banana. However, banana producers and many industries in Indonesia still facing storage problems which may lead to mechanical damage of the fruits and ripening acceleration. Therefore, we have designed food storage chamber (FSC) based on bamboo material. Bamboo was selected because of material abundance in Indonesia, economically effective, and not causing an autocatalytic reaction to the ethylene gas produced by the banana. In this research, Cavendish banana that has reached the maturity level of mature green were coated with 1% chitosan and placed inside the FSC. As control treatments, uncoated banana was also placed inside the FSC as well as uncoated banana that were placed at open space. All of the treatments were placed at 25°C temperature and observed for 9 days. Water produced by respiration was reduced by the addition of charcoal inside a fabric pouch. The result showed that treatment using...

Digital serious game design “Aksiku.bdg” facilitate young citizen's participatory planning: The case of Bandung city

This paper presents digital serious game “Aksiku.bdg” which facilitate young citizens participatory planning and how it is a suitable solution for current condition of Bandung as the case study. The case study citys development nowadays needs broader participation from all ages including the young citizen. The young citizen involvement is potential to be directed to participate in mapping Bandungs development issues such as environmental problems including: drainage, solid waste, greening, and the river in marginal area near their school.
