The current study investigates the fundamental issue of basin-type solar and identifies how to improve performance by increasing the efficiency of basin-type solar still. This research aimed at testing the addition of solar collector as preheater and condensate pipe as heat recovery in single-basin solar still to the effectiveness of condensate productivity improvement and efficiency of water distiller. The method used is testing a prototype that uses preheater and condensate pipe and a prototype that does not use the preheater and condensate pipe as a comparison. The data variable tested in this experiment is the temperature under heat absorber, which is tested by using t-test Paired Sample for Means. This experiment reveals a statistically significant difference in the average temperature of both prototypes, which is directly proportional to the increase of efficiency of the prototypes. The prototype’s efficiency calculation using preheater and condensate pipe is 60.675%, while the prototype that does not use the preheater and condensate pipe is 33.268%.
