| Summary: | <p align="justify">Pramuka island is one of the small islands which located in Kepulauan Seribu, DKI Jakarta. Pramuka island is one of the islands that encounter water scarcity when dry season. The objective of the research are to determine the amount of freshwater lens surplus/deficit on Pramuka island based on natural water balance, to determine amount of freshwater deficit based on water consumption and to determine amount of freshwater that has to be provided by new reverse osmosis installation. The research was held in June - December 2017 period. Water balance measurement is counted per year from 2012 to 2016 based on rainfall and temperature data from the nearest station, which is Tanjung Priok station, Jakarta Utara. The calculation of water balance measured by using the Thornthwaite Mather method. Based on water balance measurement, in 2016 Pramuka Island has 369 mm surplus and 669 mm deficit. Later, it discovered from the calculation that the value of sustainable yields is lower than total water need each year. In 2016 Pramuka island experienced water deficit that equal to 169 m3 per day. The rate of freshwater production that needed from new reverse osmosis instalation is 226 m3 per day.<p align="justify"> |
