| dc.description.abstract | The shortage of fresh water is increasing with the rapid growth of human
population, industry and environmental pollution. This water scarcity can be
overcome by using a solar still to convert sea water into fresh water. Solar
still has a simple construction and is easy to manufacture, but has the
disadvantage of low fresh water production. In this study, the productivity of
fresh water was increased by increasing the heat energy absorbed by the solar
still using oil palm shells as a heat storage material. The oil palm shells are
placed in the basin. There were 4 solar stills built, namely a conventional
solar still (SS1), a solar still with 5 kg of palm shells (SS2), a solar still with 3
kg of palm shells (SS3) and a solar still with 1 kg of palm shells (SS4). Four
solar stills were analyzed with regard to temperature, fresh water productivity,
energy, exergy, and economic analysis. The results showed that the use of
palm shells increased fresh water productivity by 10-39%, energy efficiency
by 13.6%, and exergy by 25.38%. Solar still using oil palm shells has a lower
fresh water productivity cost than conventional solar still, which is 0.043
